HTC Carousel Activity/Fragment (Swipeable tabs) - Sense 3.6 up to Sense 6 Samples
HTC Carousel with Tabs for Sense 3.6 up to Sense 4 (Using Activities)
Create classes and Carousel (HTC Sense Tabs)
Create simple activities
Create two classes Tab1.java; Tab2.java
Create two layout xml files - tab_1.xml; tab_2.xml;
Place any two different png icons for Tab1 and Tab2 reference
tab_1.xml
Code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="This is Tab1" />
</RelativeLayout>
tab_2.xml
Code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="This is Tab2" />
</RelativeLayout>
Tab1.java
Code:
package com.yourpackage.name;
import android.app.Activity;
import android.os.Bundle;
public class Tab1 extends Activity {
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.tab_1);
}
}
Tab2.java
Code:
package com.yourpackage.name;
import android.app.Activity;
import android.os.Bundle;
public class Tab2 extends Activity {
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.tab_2);
}
}
Create carousel (HTC Sense Tabs) and put tabs together
Create class: TabProvider.java; Remove everything inside class and place this code:
com.yourpackage.name - it is your name of package.
TabProvider.java
Code:
package com.yourpackage.name;
import com.htc.content.CarouselProvider;
[user=1299008]@supp[/user]ressWarnings("deprecation")
public class TabProvider extends CarouselProvider {
final static String AUTHORITY =
"com.yourpackage.name.TabProvider";
public TabProvider() {
super();
setupCarousel(AUTHORITY);
}
}
Open MainActivity, remove everything from class and paste this code:
MainActivity.java
Code:
package com.yourpackage.name;
import android.content.Intent;
import android.os.Bundle;
import com.htc.widget.CarouselActivity;
import com.htc.widget.CarouselHost;
public class MainActivity extends CarouselActivity {
final static String AUTHORITY =
"com.yourpackage.name.TabProvider";
public MainActivity() {
super(AUTHORITY);
}
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setGId(1);
super.onCreate(savedInstanceState);
final CarouselHost mPanelHost = getCarouselHost();
mPanelHost.addTab("Tab1", this, R.string.tab_1,
R.drawable.ic_tab1,
R.drawable.ic_tab1,
R.drawable.ic_tab1,
(new Intent("com.yourpackage.name.Tab1")));
mPanelHost.addTab("Tab2", this, R.string.tab_2,
R.drawable.ic_tab2,
R.drawable.ic_tab2,
R.drawable.ic_tab2,
(new Intent("com.yourpackage.name.Tab2")));
}
}
Configuring manifest
Dont forget, all classes have to be in Manifest.
Code:
<activity
android:name=".Tab1"
android:screenOrientation="portrait"
android:configChanges="orientation"
android:label="Tab1" >
<intent-filter>
<action android:name="com.yourpackage.name.Tab1" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity
android:name=".Tab2"
android:screenOrientation="portrait"
android:configChanges="orientation"
android:label="Tab2" >
<intent-filter>
<action android:name="com.yourpackage.name.Tab2" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
Also for HTC SDK you have to state Provider: Create provider at the end of Manifest before </application> tag
Code:
<provider
android:name="com.yourpackage.name.TabProvider"
android:authorities="com.yourpackage.name.TabProvider" />
Create ActionBar in HTC Sense Style
For all tabs in your main activity you dont need to create actionbar for each of them, you need only one Actionbar for all Tabs.
That means all Activities which will be part of TabCarousel it will use the same action bar from MainActivity.
Make Changes in your mainactivity as follow:
MainActivity.java with ActionBar
Code:
package com.yourpackage.name;
import android.content.Intent;
import android.os.Bundle;
import com.htc.widget.CarouselActivity;
import com.htc.widget.CarouselHost;
[COLOR="Red"]import com.htc.widget.ActionBarExt;
import com.htc.widget.ActionBarText;[/COLOR]
public class MainActivity extends CarouselActivity {
final static String AUTHORITY =
"com.yourpackage.name.TabProvider";
[COLOR="red"]public static ActionBarText mActionText;[/COLOR]
public MainActivity() {
super(AUTHORITY);
}
[COLOR="red"] private void SetupActionBar()
{
Object obj = new ActionBarExt(this, getActionBar());
((ActionBarExt)obj).setFullScreenEnabled(true);
((ActionBarExt)obj).enableHTCLandscape(false);
mActionText = new ActionBarText(this);
mActionText.setPrimaryText(R.string.app_name);
obj = ((ActionBarExt)obj).getCustomContainer();
((ActionBarContainer)obj).setRightDividerEnabled(true);
((ActionBarContainer)obj).addCenterView(mActionText);
}[/COLOR]
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setGId(1);
super.onCreate(savedInstanceState);
final CarouselHost mPanelHost = getCarouselHost();
[COLOR="red"]SetupActionBar();[/COLOR]
mPanelHost.addTab("Tab1", this, R.string.tab_1,
R.drawable.ic_tab1,
R.drawable.ic_tab1,
R.drawable.ic_tab1,
(new Intent("com.yourpackage.name.Tab1")));
mPanelHost.addTab("Tab2", this, R.string.tab_2,
R.drawable.ic_tab2,
R.drawable.ic_tab2,
R.drawable.ic_tab2,
(new Intent("com.yourpackage.name.Tab2")));
}
}
HTC Carousel with Tabs for Sense 4.1 up to Sense 5.5 (Using Fragments)
Create Carousel Fragment, Tabs, MainActivity
Create Tab Fragments
Now instead of Activities we will use Fragments, and it is difficult for some users. And I will try to explain how to build Carousel and not how to build Fragment Activity. But as example you can refer to my Open Source project myStore (which now converted to Fragments)
Create two classes Tab1Fragment and Tab2Fragment
Tab1Fragment.java
Code:
package your.package.name;
[COLOR="Lime"]#2[/COLOR] import android.app.Fragment;
[COLOR="lime"]#1[/COLOR] public class Tab1Fragment [B][COLOR="red"]extends Fragment[/COLOR][/B] {
Button button;
[COLOR="lime"]#3[/COLOR] public Tab1Fragment () {
}
[COLOR="lime"]#4[/COLOR] [user=439709]@override[/user]
public [B][COLOR="Red"]View onCreateView[/COLOR][/B](LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.tab1, container, false);
[COLOR="Lime"]#7[/COLOR] button = (Button) [B][COLOR="Red"]view.[/COLOR][/B]findViewById(R.id.button);
[COLOR="RoyalBlue"][I]//All your code that you need when application is first time created (see onCreate method example)[/I][/COLOR]
[COLOR="lime"]#5[/COLOR] [B][COLOR="red"]return view;[/COLOR][/B]
}
[COLOR="lime"]#6[/COLOR]
}
As you can see the Class structure is different from what you might get used.
Now you need to extend class as Fragment (#1) and import android.app.Fragment; (#2)
Then you need to have public method which represent the entire Class with the name of the Class (#3)
And Fragment uses onCreateView method instead of onCreate in Activity (#4)
And you also need return statement for the view (#5) which will be at the end after all your code inside onCreateView method
Outside onCreateView you will have all your methods for the purpose of application and those methods you will call from onCreateView method.
Example of (#7) is that how you need to use findViewById method. you need to add view. before the method. Other than tha is the same
Now create Tab2Fragment and use the same method but different layout resources.
Create Tab Provider
Code:
package your.package.name;
import com.htc.fragment.content.CarouselProvider;
public class TabProvider extends CarouselProvider {
public TabProvider(){
super();
setupCarousel(MainActivity.AUTHORITY);
}
}
Create CarouselFragment
Now to store tabs in your application we will use separate Carousel class where you will identify each tab, name, Class, icons , etc
For each tab create method for it for example
Code:
private void addTab1(CarouselHost host, String tag, int icon, int str) {
host.addTab(getActivity(), new CarouselTabSpec(tag,
str, icon, icon, icon, Tab1Fragment.class.getName()));
}
private void addAnotherTab(CarouselHost host, String tag, int icon, int str) {
host.addTab(getActivity(), new CarouselTabSpec(tag,
str, icon, icon, icon, AnotherTabFragment.class.getName()));
}
and in onActivityCreated method add your tab as in example
Code:
addAnotherTab(host, "AnotherTab", R.drawable.another_icon,
R.string.another_tab);
Carousel.java
Code:
package your.package.name;
import android.os.Bundle;
import com.htc.fragment.widget.CarouselFragment;
import com.htc.fragment.widget.CarouselHost;
import com.htc.fragment.widget.CarouselTabSpec;
public class Carousel extends CarouselFragment {
public Carousel() {
super(MainActivity.AUTHORITY);
requestCarouselFeature(CarouselFragment.FEATURE_CUSTOM_TITLE);
}
private void addTab1(CarouselHost host, String tag, int icon, int str) {
host.addTab(getActivity(), new CarouselTabSpec(tag,
str, icon, icon, icon, Tab1Fragment.class.getName()));
}
private void addTab2(CarouselHost host, String tag, int icon, int str) {
host.addTab(getActivity(), new CarouselTabSpec(tag,
str, icon, icon, icon, Tab2Fragment.class.getName()));
}
[user=439709]@override[/user]
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
final CarouselHost host = getCarouselHost();
addTab1(host, "Tab1", R.drawable.ic_tab1,
R.string.tab1);
addTab2(host, "Tab2", R.drawable.ic_tab2,
R.string.tab2);
}
}
Create MainActivity
Now MainActivity will be simple Activity with reference to Carousel class.
Code:
package your.package.name;
public class MainActivity extends Activity {
final static String AUTHORITY = "your.package.name.MainActivity";
private Carousel mCarousel = null;
public void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_ACTION_BAR_OVERLAY);
final int rootId = 1;
FrameLayout viewRoot = new FrameLayout(this);
viewRoot.setId(rootId);
setContentView(viewRoot);
mCarousel = new Carousel();
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.add(rootId, mCarousel);
ft.commit();
registerForContextMenu(viewRoot);
}
}
Configuration of Manifest
For Fragments you dont need anymore to add permission for them in Manifest (Only for Activities)
So basically with One mainactivity and two Tabs your manifest should look like
Code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="your.package.name"
android:versionCode="10"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="15"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
allowSkinChange="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="your.package.name.MainActivity"
android:screenOrientation="portrait"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<provider
android:name="your.package.name.TabProvider"
android:authorities="your.package.name.MainActivity" />
</application>
</manifest>
Make sure your provider is exaclty as follow.​
HTC Carousel with Tabs for Sense 6 (Using Fragments)
Create CarouselFragment, MainActivity, Tabs
CarouselFragment:
Code:
package com.your.pkg;
[COLOR="red"]import com.htc.fragment.widget.CarouselFragment; <!-- Make sure the imports from com.htc.fragment.*-->
import com.htc.fragment.widget.CarouselHost;
import com.htc.fragment.widget.CarouselTabSpec;[/COLOR]
importcom.your.pkg.MainActivity;
import com.your.pkg.R;
import android.os.Bundle;
public class Carousel extends [COLOR="Red"]CarouselFragment[/COLOR] {
public Carousel() {
super(MainActivity.AUTHORITY);
requestCarouselFeature(CarouselFragment.FEATURE_CUSTOM_TITLE);
}
private void addTab(CarouselHost host, String tag, int icon, int str, String tag5) {
host.addTab(getActivity(), new CarouselTabSpec(tag,
str, tag5));
}
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
final CarouselHost host = getCarouselHost();
addTab(host, [COLOR="Blue"]"FirstTab"[/COLOR], R.drawable.ic_launcher,
R.string.[COLOR="Blue"]first[/COLOR], First.class.getName());
addTab(host, [COLOR="Blue"]"SecondTab"[/COLOR], R.drawable.ic_launcher,
R.string.[COLOR="Blue"]second[/COLOR], Second.class.getName());
[COLOR="Red"]<!-- Add as many addTab(); methods as you need Tabs. The addTab() is universal-->[/COLOR]
}
}
MainActivity
Code:
public class MainActivity extends MfMainActivity {
public final static String AUTHORITY = "mikrosmile.kontrol.MainActivity";
private Carousel mCarousel = null;
static Window window;
@Override
protected void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_ACTION_BAR_OVERLAY);
super.onCreate(savedInstanceState);
final int rootId = 1;
FrameLayout viewRoot = new FrameLayout(this);
viewRoot.setId(rootId);
setContentView(viewRoot);
mCarousel = new Carousel();
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.add(rootId, mCarousel);
ft.commit();
registerForContextMenu(viewRoot);
getWindow().setFormat(1);
}
}
Tabs
Code:
Any Activity or Fragment
HTC's Release to Refresh method (Swipe2Refresh)
The Release to Refresh is like this:
View attachment 2711413
It can be added to any View. I will show example how to add it to ListView
Code:
[COLOR="red"]import com.htc.widget.OnPullDownListener;[/COLOR]
public static ActionBarRefresh aRefresh;
@Override
protected void onCreate(Bundle bundle) {
//Adding inside onCreate method of you listActivity
list.[COLOR="Red"]setOnPullDownListener(new PullDown());[/COLOR]
}
public class PullDown implements OnPullDownListener{
//just a class inside your listActivity
@Override
public void onGapChanged(int top, int bottom) {
if(top != 0){
actionbarext.getCustomContainer().setRotationMax(top);
actionbarext.getCustomContainer().setRotationProgress(bottom);
//actionbarext.getCustomContainer is your ActionBar container
}
}
@Override
public void onPullDownCancel() {
actionbarext.getCustomContainer().setUpdatingState(0);
}
@Override
public void onPullDownRelease() {
actionbarext.getCustomContainer().setUpdatingState(0);
//do whatever you need to update the list here, you can call a method or AsyncTask from here
}
@Override
public void onPullDownToBoundary() {
actionbarext.getCustomContainer().setRotationProgress(actionbarext.getCustomContainer().getRotationMax());
}
}
Code:
On your method to update list add this to onPreExecute
aRefresh.setVisibility(View.VISIBLE);
aRefresh.setPrimaryText("Updating...");
actionbartext.setPrimaryVisibility(View.GONE);
actionbartext.setSecondaryVisibility(View.GONE);
When you finish your task to update list, inside onPostExecute add this
actionbarext.getCustomContainer().setUpdatingState(0);
Code:
Inside your method to SetupActionBar add this
aRefresh = new ActionBarRefresh(c);
aRefresh.setVisibility(View.GONE);
actionbarext.getCustomContainer().addCenterView(aRefresh);
​
Add HTC Sense 6 Theme support to your app
Inside your MainActivity add this method
Code:
public static int getHtcThemeID(Context context, int i)
{
return HtcWrapConfiguration.getHtcThemeId(context, i);
}
And in onCreate method add this
Code:
setTheme(getHtcThemeID(context, 0));
This method is returning current Choosen theme ID by Variable from 0 to 3.
So, when you open Personalization - Theme. You see 4 Themes. First 3 has different Color boxes at the top. The first 3 is the actual variable integer from 0 - 3.
So, if you want to get , let's say Red color from Theme 2. You have to Choose Theme 2 in the Theme Settings, and in the app use this:
Code:
setTheme(getHtcThemeID(context, 3));
Once you change Theme, it will also use The Orange color from Theme 1, and the Purple Color from Theme 3
​
Add SlidingMenu to your Sense application
To make the sliding menu in your application like Mail app or File manager app, follow this:
View attachment 2876504
Code:
public class MainActivity extends [COLOR="Red"]SlidingActivity [/COLOR]{
[COLOR="red"]private SlidingMenu mSlidingMenu;[/COLOR]
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
window = getWindow();
setContentView(R.layout.activity_main);
[COLOR="red"]setBehindContentView(R.layout.activity_behind);
initSlidingMenu();[/COLOR]
SetupActionBar(this);
}
private void initSlidingMenu()
{
mSlidingMenu = getSlidingMenu();
[COLOR="red"]mSlidingMenu.setBehindWidth(500);[/COLOR] [COLOR="Lime"]//any width as you want[/COLOR]
mSlidingMenu.setFadeDegree(0.5F);
mSlidingMenu.setFadeEnabled(true);
mSlidingMenu.setMode(0);
mSlidingMenu.setTouchModeAbove(0);
mSlidingMenu.setOnOpenedListener(new com.htc.widget.SlidingMenu.OnOpenedListener() {
public void onOpened()
{
initSlidingMenuContent();
}
});
}
private void initSlidingMenuContent(){
[COLOR="red"] mSlidingMenu.setShadowWidth(50);
mSlidingMenu.setShadowDrawable(ICservices.getShadowDrawable());[/COLOR][COLOR="Lime"]//any shadow drawable you want
//here is all your code that represent the behind layout. it can be listview or any other View you need[/COLOR]
}
[COLOR="SeaGreen"]//if you want to have a toggle at the actionbar, also add OnClickListener to ActionbarTextView and add IconView to Actionbar[/COLOR]
}
add this permission to Manifest:
[COLOR="red"]<uses-permission android:name="com.htc.permission.APP_DEFAULT" />[/COLOR]

Add 3 Dot menu to actionbar
For the Menu in actionbar you just implement simple menu method, but you dont need to use menu.xml for it.
Also you dont need to create string values for Menu, it will generate automatically for you, the icon, and the name.
This is method to create Menu in ActionBar. Add it in MainActivity before SetupActionBar() method
Code:
public void onCreateContextMenu (ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
menu.add("ContextMenu");
}
[user=439709]@override[/user]
public boolean onCreateOptionsMenu (Menu menu) {
menu.add(1, 1, 1, R.string.settings);
return true;
}
public boolean onOptionsItemSelected(MenuItem menuitem)
{
boolean flag = true;
switch (menuitem.getItemId())
{
case 1:
startActivity(new Intent(this, Settings.class));
break;
}
return flag;
}
This is your new MainActivity with Menu
Code:
package com.yourpackage.name;
import android.content.Intent;
import android.os.Bundle;
import com.htc.widget.CarouselActivity;
import com.htc.widget.CarouselHost;
import com.htc.widget.ActionBarExt;
import com.htc.widget.ActionBarText;
[COLOR="Red"]import android.view.ContextMenu;
import android.view.Menu;
import android.view.MenuItem;[/COLOR]
public class MainActivity extends CarouselActivity {
final static String AUTHORITY =
"com.yourpackage.name.TabProvider";
public static ActionBarText mActionText;
public MainActivity() {
super(AUTHORITY);
}
[COLOR="red"]public void onCreateContextMenu (ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
menu.add("ContextMenu");
}
[user=439709]@override[/user]
public boolean onCreateOptionsMenu (Menu menu) {
menu.add(1, 1, 1, R.string.settings);
return true;
}
public boolean onOptionsItemSelected(MenuItem menuitem)
{
boolean flag = true;
switch (menuitem.getItemId())
{
case 1:
startActivity(new Intent(this, Settings.class));
break;
}
return flag;
}[/COLOR]
private void SetupActionBar()
{
Object obj = new ActionBarExt(this, getActionBar());
((ActionBarExt)obj).setFullScreenEnabled(true);
((ActionBarExt)obj).enableHTCLandscape(false);
mActionText = new ActionBarText(this);
mActionText.setPrimaryText(R.string.app_name);
obj = ((ActionBarExt)obj).getCustomContainer();
((ActionBarContainer)obj).setRightDividerEnabled(true);
((ActionBarContainer)obj).addCenterView(mActionText);
}
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setGId(1);
super.onCreate(savedInstanceState);
final CarouselHost mPanelHost = getCarouselHost();
SetupActionBar();
mPanelHost.addTab("Tab1", this, R.string.tab_1,
R.drawable.ic_tab1,
R.drawable.ic_tab1,
R.drawable.ic_tab1,
(new Intent("com.yourpackage.name.Tab1")));
mPanelHost.addTab("Tab2", this, R.string.tab_2,
R.drawable.ic_tab2,
R.drawable.ic_tab2,
R.drawable.ic_tab2,
(new Intent("com.yourpackage.name.Tab2")));
}
}
HTC AlertDialog​
In order to have alertdialog you need to have OnClickListener and inside OnClickListener you paste alertDialog.
Code:
public void onItemClick(HtcAdapterView<?> parent, View view, int position, long id) {
[COLOR="red"]HtcAlertDialog.Builder[/COLOR] alertDialog = new [COLOR="red"]HtcAlertDialog.Builder[/COLOR]([B]YourActivity.this[/B]);
alertDialog.setTitle(R.string.title_txt);
alertDialog.setMessage(R.string.message_txt);
alertDialog.setIcon(R.drawable.icon);
alertDialog.setPositiveButton(R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int which) {
//Do your actions here when user click Yes
}
});
alertDialog.setNegativeButton(R.string.no, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
//Do your action here when user click No.. or just cancel dialog using follow..
dialog.cancel();
}
});
alertDialog.show();
}
As you can see Dialog is not so difficult, but need to identify exaclty which Builder you are gonna use.
YourActivity.this - means the activity where you create the dialog
You can also see available options of what you can implement inside dialog.. like 3 buttons.
Start typing alertDialog. finish with the dot and in Eclipse there will be new pop-up window and you can add some more
Also dont forget alertDialog.show(); at the end, otherwise Dialog wont shows​
HTC ListView and HtcListActivity. ​
There are two ways of implementing Htc List view. You can use Simple Activity, Fragment or just easy use HtcListActivity extension.
For full htc style you need to use Main List layout, and Details layout + List adapter.
Example using Activity
Code:
public class AboutActivity extends Activity {
[COLOR="Red"]HtcListView lv1;[/COLOR]
[user=439709]@override[/user]
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.about_activity);
ArrayList<AboutDetails> image_details = GetSearchResults();
[COLOR="red"]final HtcListView lv1 = (HtcListView) findViewById(R.id.about_list);[/COLOR]
[user=1299008]@supp[/user]ressWarnings("unused")
lv1.setAdapter(new AboutListBaseAdapter(this, image_details));
lv1.setOnItemClickListener(new HtcAdapterView.OnItemClickListener() {
Vibrator vibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
[user=439709]@override[/user]
public void onItemClick(HtcAdapterView<?> a, View v, int position, long id) {
vibrator.vibrate(50);
Object o = lv1.getItemAtPosition(position);
final AboutDetails obj_itemDetails = (AboutDetails)o;
}
});
}
private ArrayList<AboutDetails> GetSearchResults(){
ArrayList<AboutDetails> results = new ArrayList<AboutDetails>();
AboutDetails item_details = new AboutDetails();
item_details.setName(R.string.mikrosmile);
item_details.setItemDescription(R.string.mikrosmile_info);
item_details.setImageNumber(1);
results.add(item_details);
return results;
}
}
AboutDetails
Code:
public class AboutDetails {
public int getName() {
return name;
}
public void setName(int name) {
this.name = name;
}
public int getItemDescription() {
return itemDescription;
}
public void setItemDescription(int itemDescription) {
this.itemDescription = itemDescription;
}
public int getImageNumber() {
return imageNumber;
}
public void setImageNumber(int imageNumber) {
this.imageNumber = imageNumber;
}
private int name ;
private int itemDescription;
private int imageNumber;
}
AboutListBaseAdapter
public class AboutListBaseAdapter extends BaseAdapter {
private static ArrayList<AboutDetails> aboutDetailsrrayList;
private Integer[] imgid = {
R.drawable.mikrosmile,
};
private LayoutInflater l_Inflater;
public AboutListBaseAdapter(Context context, ArrayList<AboutDetails> results) {
aboutDetailsrrayList = results;
l_Inflater = LayoutInflater.from(context);
}
public int getCount() {
return aboutDetailsrrayList.size();
}
public Object getItem(int position) {
return aboutDetailsrrayList.get(position);
}
public long getItemId(int position) {
return position;
}

HTC ListView Example by xcesco89

Add HTC Sense Skin support.
In AndroidManifest add this line inside <application tag and before first <activity tag where you have your MainActivity
Code:
<application
[COLOR="Red"]allowSkinChange="true"[/COLOR]
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.yourpackage.name.MainActivity"
There will be Error in Manifest, says "Attribute is missing the Android namespace prefix"
It is fine, to fix it go to - Project -> Clean; Choose your Application and click Ok​
Add reference library to use full HTC app experience
Sense 6
Download this package - View attachment addon-htc_opensense_apis-htc-19.zip
Place the extracted folder to <location of android SDK>\android\sdk\add-ons\
Choose HTC OpenSense SDK 19 when you start building your application. Profit
Sense 5 and below
Refer to this, thanks to Jonny
Make sure HTCExtension lib is appear in your Eclipse project​
Use HTCPreference Activity
Htc Preference is the same as normal Preference but you need to follow some rules when you want to have this.
First in your Preference activity (for example you already have one) change PreferenceActivity to HtcPreferenceActivity.
import com.htc.preference.*;
In prefs.xml (or any other xml file you have your preferences in) make sure everything is using this way
This is original android way.
<PreferenceScreen> </PreferenceScreen>
This is Htc way
<com.htc.preference.HtcPreferenceScreen> </com.htc.preference.HtcPreferenceScreen>
So basically to every single item in preferences you need to add com.htc.preference.Htc****
Here is prefs.xml example
Code:
<?xml version="1.0" encoding="utf-8"?>
<[COLOR="Red"]com.htc.preference.Htc[/COLOR]PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" >
<[COLOR="red"]com.htc.preference.Htc[/COLOR]CheckBoxPreference
android:title="@string/load_icons"
android:summary="@string/load_icons_summary"
android:defaultValue="true"
android:key="show_dialog">
</[COLOR="red"]com.htc.preference.Htc[/COLOR]CheckBoxPreference>
<[COLOR="red"]com.htc.preference.Htc[/COLOR]SwitchPreference
android:title="@string/load_skins"
android:summary="@string/load_skins_summary"
android:switchTextOn="@string/on"
android:switchTextOff="@string/off"
android:defaultValue="true"
android:key="skins_on_start">
</[COLOR="red"]com.htc.preference.Htc[/COLOR]SwitchPreference>
</[COLOR="red"]com.htc.preference.Htc[/COLOR]PreferenceScreen>
This is how Pref activity should be
Code:
package com.yourpackage.name;
import android.os.Bundle;
import android.view.View;
import com.htc.widget.ActionBarContainer;
import com.htc.widget.ActionBarExt;
import com.htc.widget.ActionBarText;
[COLOR="red"]import com.htc.preference.*;[/COLOR]
public class Settings extends [COLOR="red"]Htc[/COLOR]PreferenceActivity {
private ActionBarExt actionBarExt=null;
private ActionBarText actionBarText=null;
private ActionBarContainer actionBarContainer=null;
private void SetupActionBar() {
actionBarExt=new ActionBarExt(this,getActionBar());
actionBarExt.enableHTCLandscape(false);
actionBarContainer=actionBarExt.getCustomContainer();
actionBarText=new ActionBarText(this);
actionBarText.setPrimaryText(R.string.settings);
actionBarContainer.addCenterView(actionBarText);
actionBarContainer.setRightDividerEnabled(true);
}
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.prefs);
}
SetupActionBar();
}
}
If you cannot import com.htc.preference.*; (Eclipse will give you error) it means you dont have HtcExtension lib. Make sure you added it before doing this.

Great guide! HTC Dialog isn't hard, just the same as the normal dialog, but putting Htc before the dialog stuff, right?
Looking forward to the ListView guide!

This is not image actually, it is skin support..
I was planning to write about it later ))
OK in manifest after <application tag add this line
allowSkinChange="true"
You will have error. Go to Project and perform a Clean . try and report back

Weird.. Cannot edit ..
So this line should be in the same pack where you have android icon and theme info before the first activity tag

add an HtcListView it's quite simple!
this works exactly as the android ListView
a simple example:
(as base i've used TabPlus4Demo a sample project in OpenSense SDK samples )
main.xml
HTML:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<com.htc.widget.HtcListView
android:id="@+id/listView1"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
(Note that you need to use com.htc.widget.HtcListView instead of ListView )
the code:
Code:
public class SimpleTab extends Fragment {
public HtcListView lv;
[user=439709]@override[/user]
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
if(getArguments() != null) {
int resId = getArguments().getInt("LAYOUT");
if(resId != 0)
return inflater.inflate(resId, null);
}
ViewGroup rootView = (ViewGroup) inflater.inflate(
R.layout.main, container, false);
[B]//Find the view[/B]
lv = (HtcListView) rootView.findViewById(R.id.listView1);
[B]//create the list[/B]
List<String> list = new ArrayList<String>();
[B]//add some list Items ( if you want a custom text , just use list.add("blahblah")[/B]
for (int i =0; i<40; i++) {
list.add("Test"+i);
}
[B]//create the adapter[/B]
ArrayAdapter<?> adapter = new ArrayAdapter<String>(this.getActivity(),
android.R.layout.simple_list_item_1, list);
[B]//Set the adapter[/B]
lv.setAdapter(adapter);
[B]/*
create and set the Listener
you can also implement this in your activity with
"public class youractivity extends Activity implements OnItemClickListener"
then use lv.setOnItemClickListener(this)
*/[/B]
lv.setOnItemClickListener(new OnItemClickListener() {
[user=439709]@override[/user]
public void onItemClick(HtcAdapterView<?> arg0, View v,
int pos, long id) {
[B]//make a Toast Message that displays the Selected item NAME[/B]
Toast.makeText(v.getContext(),"pressed: "+ lv.getItemAtPosition(pos), Toast.LENGTH_SHORT).show();
[B]/*
if you want t perform something different for each item you can use the case statement
switch(pos){
case 0:
Toast.makeText(v.getContext(), "HI!", Toast.LENGTH_SHORT).show();
break;
case 1:
Toast.makeText(v.getContext(), "HELLO!", Toast.LENGTH_SHORT).show();
break;
[...]
case 39:
//do something
break;
*/[/B]
}
});
return rootView;
}
}

this is not part of OpenSense SDK.. they wont open it. You need to create own framework..
this is actually part of HtcPreferenceActivity which you cant create in Eclipse without proper libs..

Other than that you can create similar png.9 image and make it looks like )

i think you can create a custom row layout, create a new custom adapter and set the content with your new adapter

Text input with DialogFragment

I am trying to get a value that user enters into a Dialog, using the recommended DialogFragment class for it, the Dialog constructs and runs fine, but I cannot return the value of the EditText parameter to the parent class, without get a Null pointer exception.
My DialogHost class, this constructs, returns and links the parent to its buttons.
Code:
package jo.app.co;
import android.app.Activity;
import android.app.AlertDialog;
import android.app.Dialog;
import android.app.DialogFragment;
import android.content.DialogInterface;
import android.os.Bundle;
import android.view.LayoutInflater;
public class DialogHost extends DialogFragment {
public interface NoticeDialogListener {
public void onDialogPositiveClick(DialogFragment dialog);
public void onDialogNegativeClick(DialogFragment dialog);
}
NoticeDialogListener mListener;
[user=439709]@override[/user]
public void onAttach(Activity activity) {
super.onAttach(activity);
try {
mListener = (NoticeDialogListener) activity;
} catch (ClassCastException e) {
throw new ClassCastException(activity.toString());
}
}
[user=439709]@override[/user]
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
builder.setView(inflater.inflate(R.layout.dialog_add, null))
.setPositiveButton("Save", new DialogInterface.OnClickListener() {
[user=439709]@override[/user]
public void onClick(DialogInterface dialog, int id) {
mListener.onDialogPositiveClick(DialogHost.this);
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
DialogHost.this.getDialog().cancel();
}
});
return builder.create();
}
}
My MainActivity
Code:
package jo.app.co;
import android.app.DialogFragment;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.util.Log;
import android.widget.EditText;
public class MainActivity extends FragmentActivity implements DialogHost.NoticeDialogListener {
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
showNoticeDialog();
}
public void showNoticeDialog() {
DialogFragment dialog = new DialogHost();
dialog.show(getFragmentManager(), "DialogHost");
}
[user=439709]@override[/user]
public void onDialogPositiveClick(DialogFragment dialog) {
EditText myText = (EditText) findViewById(R.id.item_added);
try {
Log.d ("IN TRY", myText.getText().toString());
}
catch (Exception e) {
Log.e ("IN CATCH", e.toString());
}
}
[user=439709]@override[/user]
public void onDialogNegativeClick(DialogFragment dialog) {
Log.d ("INMAIN", "REACHED NEG");
}
}
This is my layout for the add item dialog.
Code:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<EditText
android:id="@+id/item_added"
android:inputType="text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="16dp"
android:layout_marginLeft="4dp"
android:layout_marginRight="4dp"
android:layout_marginBottom="4dp"
android:hint="@string/hint_add_item" />
</LinearLayout>

It's because in your main activity you are trying to call findViewById:

This is not possible since the layout of the activity is not the one the dialog is using. There are multiple ways of doing this, for instance call findViewById in the dialog's onPositiveButtonListener and pass that value through your interface. It might be that you need to use the LayoutInflator in the onCreateDialog, set
LinearLayout linearl = (LinearLayout) inflater.inflate(...) and get the EditText from there. You then call setView(linearL) instead.

I tried calling findViewById method in the onClick method in the Dialog class, but the function is not defined for a DialogInterface.onClickListner, I modified it to linearl method you told but I cannot get it to work either.
Could you make the changes in the 2 snippets above, it would be very helpful!

You'll have to setup listeners fo this and pass the string or whetever you want to pass to back to the activity which in its turn can handle it (do it by itself or pass this to another fragement).
Although not so much votes (0) the last answer here on stackoverflow has exeactly what you need.

Yeah, have a look at the posts about using the debuggers of Eclipse or AndroidStudio.
They help you to understand what your app does. You can see which commands get executed at which time and the you can see the values of variables.
That might help you finding the problem.
(This doesn't require an Exception.)

return false;
}
}
return true;
}
});
The output of the main activity code is Toasting all children text on screen.
But, what I want to do, is to set "is_selected" in "ImageView" with Drawable image.
After long click on the group item, ALL children of this group get selected.

Dears,
What is wrong with this question?
Is it easy question so it does not worth to answer?
Or it is tough and no body know the answer?
I'm stick with this sine weeks

[Q]Android Bluetooth - mHandler and manageConnectedSocket errors

Hi! I am beginner in Android programming. I would like to learn how to send a string between 2 devices via Bluetooth. I was trying to write a code on the base of page http://developer.android.com/guide/topics/connectivity/bluetooth.html
I got 3 errors. The first one is, that the MainActivity is underlined red in the following row:
Code:
public class MainActivity extends Activity {
It says: 'The blank final field mHandler may not have been initialized'
The other 2 errors are shown in the AcceptThread and ConnectThread classes. The following row is underlined red:
Code:
manageConnectedSocket(socket);
It says: 'The method manageConnectedSocket(BluetoothSocket) is undefined for the type AcceptThread' and 'The method manageConnectedSocket(BluetoothSocket) is undefined for the type ConnectThread'
Could you please tell me, how to fix the problems and explain me, what were the problems? Thanks in advance.
