Hi all,
I'm trying to have transparent PNGs on my screen.
What is the best way to doing this ? I'm in C#, I tried DirectX, but it doesn't work.
What am I doing wrong ?
My code :
Code:
using System;
using System.Drawing;
using System.Windows.Forms;
using Microsoft.WindowsMobile.DirectX;
using Microsoft.WindowsMobile.DirectX.Direct3D;
using System.Runtime.InteropServices;
namespace Microsoft.Samples.MD3DM
{
// The main class for this sample
public class SimpleSMS : Form
{
// Our global variables for this project
Device device = null;
Texture texture = null;
Sprite sprite = null;
Rectangle rect;
public SimpleSMS()
{
// Set the caption
this.Text = "SimpleSMS";
this.MinimizeBox = false;
}
// Prepare the rendering device
public bool InitializeGraphics()
{
try
{
// Now let's setup our D3D parameters
PresentParameters presentParams = new PresentParameters();
presentParams.Windowed = true;
presentParams.SwapEffect = SwapEffect.Discard;
device = new Device(0, DeviceType.Default, this, CreateFlags.None, presentParams);
this.OnCreateDevice(device, null);
}
catch (DirectXException)
{
return false;
}
return true;
}
void OnCreateDevice(object sender, EventArgs e)
{
texture = TextureLoader.FromFile(device, @"badge.png");
sprite = new Sprite(device);
rect = new Rectangle(0, 0, 48, 48);
}
// All rendering for each frame occurs here
private void Render()
{
if (device != null)
{
device.Clear(ClearFlags.Target, System.Drawing.Color.Black, 1.0f, 0);
//Begin the scene
device.BeginScene();
device.RenderState.SourceBlend = Blend.SourceAlpha;
device.RenderState.DestinationBlend = Blend.InvSourceAlpha;
device.RenderState.AlphaBlendEnable = true;
sprite.Begin(SpriteFlags.AlphaBlend);
sprite.Draw(texture, rect, new Vector3(0.0f, 0.0f, 0.0f), new Vector3(100.0f, 100.0f, 0.0f), Color.White.ToArgb());
sprite.End();
//End the scene
device.EndScene();
device.Present();
}
}
// Called to repaint the window
protected override void OnPaint(System.Windows.Forms.PaintEventArgs e)
{
// Render on painting
this.Render();
// Render again
this.Invalidate();
}
// Called to repaint the window background
protected override void OnPaintBackground(
System.Windows.Forms.PaintEventArgs e)
{
// Do nothing to ensure that the rendering area is not overdrawn
}
// Close the window when Esc is pressed
protected override void OnKeyPress(
System.Windows.Forms.KeyPressEventArgs e)
{
// Esc was pressed
if ((int)(byte)e.KeyChar == (int)System.Windows.Forms.Keys.Escape)
this.Close();
}
/// <summary>
/// The main entry point for the application.
/// </summary>
static void Main()
{
SimpleSMS frm = new SimpleSMS();
// Initialize Direct3D
if (!frm.InitializeGraphics())
{
MessageBox.Show("Could not initialize Direct3D. " +
"This tutorial will exit.");
return;
}
Application.Run(frm);
}
}
}
Thanks for answers,
Scuse my bad english :-/
Not sure this helps, but RLTODAY works very well with transparent pngs in any WM version, and recently he released the source code:
http://rotlaus-software.de/forum/index.php?topic=1847.0
You can use ImagingFactory in OpenNETCF or other wrapper over the internet. PNGs with alpha work work for me.
AlphaControls
There is a project on Codeplex that can help you with transparency called AlphaControls. Also have a look on codeproject at the iPhone app clone

Click to expand...
Click to collapse
Thank you all for answers ...
I tried OpenNetCF, without any result.
Do you have a piece of code in example ?
Try this:

Hi,
since the compability package does not ship PreferenceListFragment, I built my own one, which I am using in my gtalk widget app.
I was asked for the source, so here it is. It's quite a hacky workaround..
Edit: Someone asked about the license: Use it however you like

How to use:
Code:
public class Settings extends FragmentActivity implements OnPreferenceAttachedListener, OnPreferenceChangeListener, OnPreferenceClickListener{
private Preference filterPref;
private ViewPager viewPager;
public void onCreate(Bundle b){
super.onCreate(b);
setContentView(R.layout.settings);
viewPager = (ViewPager) findViewById(R.id.pager);
PagerAdapter adapter = new PagerAdapter(getSupportFragmentManager(), this);
viewPager.setAdapter(adapter);
TitlePageIndicator titleIndicator = (TitlePageIndicator) findViewById(R.id.titles);
titleIndicator.setViewPager(viewPager);
titleIndicator.setFooterIndicatorStyle(IndicatorStyle.Underline);
viewPager.setCurrentItem(1);
}
//setup your onPreferenceClickListener/onPreferenceChangeListener here
[user=439709]@override[/user]
public void onPreferenceAttached(PreferenceScreen root, int xmlId){
if(root == null)
return; //for whatever reason in very rare cases this is null
if(xmlId == R.xml.widget_settings){ //example id
root.findPreference("somePreference").setOnPreferenceClickListener(this);
}
}
//handle your preferenceChanged events here (if needed)
[user=439709]@override[/user]
public boolean onPreferenceChange(Preference preference, Object newValue) {
return true;
}
//handle your preferenceClick events here (if needed)
[user=439709]@override[/user]
public boolean onPreferenceClick(Preference pref){
return true;
}
}
and the adapter I am using:
Code:
public class PagerAdapter extends FragmentPagerAdapter implements TitleProvider{
PreferenceListFragment[] fragments;
String[] titles;
public PagerAdapter(FragmentManager fm, Context context) {
super(fm);
fragments = new PreferenceListFragment[4];
fragments[0] = new PreferenceListFragment(R.xml.settings);
fragments[1] = new PreferenceListFragment(R.xml.widget_settings);
fragments[2] = new PreferenceListFragment(R.xml.s_widget_settings);
fragments[3] = new PreferenceListFragment(R.xml.color_settings);
titles = new String[4];
titles[0] = context.getString(R.string.main_settings);
titles[1] = context.getString(R.string.widget_settings);
titles[2] = context.getString(R.string.s_widget_settings);
titles[3] = context.getString(R.string.color_settings_main);
}
[user=439709]@override[/user]
public Fragment getItem(int position){
return fragments[position];
}
[user=439709]@override[/user]
public int getCount() {
return fragments.length;
}
[user=439709]@override[/user]
public String getTitle(int position) {
return titles[position];
}
}
Lastly you will need this xml file: preference_list_content.xml (belongs into /res/layout/) (pulled from aosp)
Code:
<?xml version="1.0" encoding="utf-8"?>

Thank you for sharing!
THANK YOU, much appropriated
Working fine on my devices (Nexus S and GNex), but received logs with crashes here:
Code:
((OnPreferenceAttachedListener)getActivity()).onPreferenceAttached(getPreferenceScreen(), xmlId);
NullPointerException here:
Code:
@Override
public void onPreferenceAttached(PreferenceScreen root, int xmlId) {
List<PreferenceScreen> rootPref=new ArrayList<PreferenceScreen>() ;
rootPref.add(root);
root.getSharedPreferences().registerOnSharedPreferenceChangeListener(
this);
hm, I received logs, that the listview is null when bindPreferences() is called. =/
thank you, i will use this on my application NSTools
Hello, i ma new at this and i am trying to understand the code, what exactly are "R.array.display_filter_array" and "R.layout.preference_list_content", these are the only things i have left to try this code, hope you can help me
Thank you
I added the missing layout file in the first post.
I also added a check for nullpointer in onPreferenceAttached().
R.array.display_filter_array correspondends to a string array I defined.
getResources().getStringArray(int stringId) will return an array of localized strings defined in res/values/strings.xml.
Thank you so much for this! I've been wracking my brain for a long time to come up with a way to use a PreferenceFragment on pre-Honeycomb devices, and this fits my needs exactly. So much love.
I'll let you know if I run across any issues.
Hi.
First I'd like to thank you for sharing this.
I have an issue with this : each preference row is only taking the width it's really nead, instead of using all width available like any Preference view. The result is kinda ugly (widgets of preferences not aligned in the right and click area way too little).
But if I start a new Activity and come back, they are well displayed. The only difference between the code I use and yours is I don't use a ViewPage, I directly use the ListFragment as Fragment.
Can someone help me please ?
Thanks in advance.
Hey guys, I just wanted to share a different initialization scheme. I couldn't get the activity to survive orientation change without fc. So i came up with this...
Extended PreferenceFragment
Code:
package org.teameos.settings.device;
import android.os.Bundle;
public class DiagPreferences extends PreferenceListFragment {
public static DiagPreferences newInstance(int xml) {
DiagPreferences f = new DiagPreferences(xml);
Bundle b = new Bundle();
b.putInt("xml", xml);
f.setArguments(b);
return f;
}
public DiagPreferences(int xmlId) {
// TODO Auto-generated constructor stub
super(xmlId);
}
public DiagPreferences() {
super();
}
The adapter
Code:
public ViewPagerAdapter(Context context, FragmentManager fm) {
super(fm);
mContext = context;
mFragments = new ArrayList<Pair<Fragment, String>>();
mFragments.add(Pair.create(
(Fragment) UpdatesPreferences.newInstance(R.xml.updates_and_menus),
mContext.getString(R.string.eos_ota_menus)));
mFragments.add(Pair.create((Fragment) DiagPreferences.newInstance(R.xml.diagnostics),
mContext.getString(R.string.eos_diag)));
mFragments.add(Pair.create((Fragment) PrlPreferences.newInstance(R.xml.prl_management),
mContext.getString(R.string.prl_management)));
}
using the above code (you cant use constructors) and using newInstance its not working
you need modify this in Oncreate
Code:
super.onCreate(b);
if(b != null){
xmlId = b.getInt("xml");
}else
{
xmlId = getArguments().getInt("xml");
}
This code gave me a warning about memory leak we shouls use WeakReference or use as static
Code:
private Handler mHandler = new Handler() {
[user=439709]@override[/user]
public void handleMessage(Message msg) {
switch (msg.what) {
case MSG_BIND_PREFERENCES:
bindPreferences();
break;
}
}
};
like this:
Code:
private [B][COLOR="Red"]static[/COLOR] [/B]Handler mHandler = new Handler() {
[user=439709]@override[/user]
public void handleMessage(Message msg) {
switch (msg.what) {
case MSG_BIND_PREFERENCES:
bindPreferences();
break;
}
}
};
and in all "dependencies" of that function like bindPreferences and so on.
Ps AMAZING Work BTW thanks a lot
Great code, but I can't find TitleProvider anywhere... I believe it used to be part of PagerViewer? How to remove this?
A user can select an item from my view to get a dialog showing different strings. Below that is a button. I would like the button, when pressed, to run a shell command. I have no idea how I would go about doing this.
Basically, how can I make the button have a command set to it, which when a user selects something in the dialog popup, runs the command + the string in the chosen view?
The class:
Code:
public static class DataSyncPreferenceFragment extends PreferenceFragment {
[user=439709]@override[/user]
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.pref_data_sync);
// Bind the summaries of EditText/List/Dialog/Ringtone preferences
// to their values. When their values change, their summaries are
// updated to reflect the new value, per the Android Design
// guidelines.
bindPreferenceSummaryToValue(findPreference("sync_frequency"));
}
}
The button
Code:
public void button1(View v) {
switch (v.getId()) {
case R.id.button1:
try {
Runtime.getRuntime().exec(new String[] { "su", "-c","HOW_DO_I_ADD_THINGS_HERE" });
} catch (IOException e) {
e.printStackTrace();
}
break;
}
}
My arrays look like this:
Code:
<string-array name="pref_sync_frequency_titles">
<item>Normal</item>
<item>Smaller</item>
<item>Smallest</item>
</string-array>
<string-array name="pref_sync_frequency_values">
<item>320</item>
<item>280</item>
<item>220</item>
</string-array>
Any help would be appreciated. I'm too new to know these things, sadly. :crying:
Here's a possible solution to what you're trying to achieve. I've had to implement something like this in my apps before, and I've made use of this helpful StackOverflow question.
Code:
new AlertDialog.Builder(this.getActivity())
//Add your titles array to the dialog (in single choice mode)
.setSingleChoiceItems(R.array.pref_sync_frequency_titles, 0, null)
.setPositiveButton(R.string.ok_button_label, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
dialog.dismiss();
int selectedPosition = ((AlertDialog)dialog).getListView().getCheckedItemPosition();
//Get the corresponding values Array
String[] strValues = getActivity().getResources().getStringArray(R.array.pref_sync_frequency_values);
//Get the corresponding value that was clicked
String yourValue = strValues[selectedPosition];
try {
Runtime.getRuntime().exec(new String[] { "su", "-c","HOW_DO_I_ADD_THINGS_HERE" + yourValue });
} catch (IOException e) {
e.printStackTrace();
}
}
})
.show();
Let me know how that works!
Hi guys, could anyone help me with this?
I am trying to develop an application that could automatic change the ringtone for incoming calls, because all the existed applications which has this feature could not works well on my Galaxy S7 Edge,
but then I found out is't not that easy to change ringtone on Galaxy S7 Edge.
I am tried with these code:
File sdFile = new File("/mnt/storage/26D9-150C/test.mp3");
ContentValues values = new ContentValues();
values.put(MediaStore.MediaColumns.DATA, sdFile.getAbsolutePath());
values.put(MediaStore.MediaColumns.TITLE, sdFile.getName());
values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/*");
values.put(MediaStore.Audio.Media.IS_RINGTONE, true);
values.put(MediaStore.Audio.Media.IS_NOTIFICATION, false);
values.put(MediaStore.Audio.Media.IS_ALARM, false);
values.put(MediaStore.Audio.Media.IS_MUSIC, false);
Uri uri = MediaStore.Audio.Media.getContentUriForPath(sdFile.getAbsolutePath());
getContentResolver().delete(uri ,null ,null);//if not delete, maybe it will cause some error.
Uri newUri = this.getContentResolver().insert(uri, values);
RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_RINGTONE, newUri);
These code works fine on other devices, also on the Galaxy S7 Edge, you can see the new ringtone with code below, the ringtone changed into the target file, but when you received a phone call it's not the the ringtone that I set ! It's still the old ringtone before I run that code above. What's the problem ????? And I checked the ringtone from "Setting-Sound and vibrate-ringtone-incoming ringtone" it's never changed!!!
And I have granted the WRITE_SETTINGS permission already.
private Uri getSystemDefaultRingtoneUri() {
return RingtoneManager.getActualDefaultRingtoneUri(this, RingtoneManager.TYPE_RINGTONE);//RingtoneManager.TYPE_ALL
}
private String getRealPath(Uri fileUrl) {
String fileName = null;
Uri filePathUri = fileUrl;
if (fileUrl != null) {
if (fileUrl.getScheme().toString().compareTo("content") == 0) {
Cursor cursor = mContext.getContentResolver().query(fileUrl, null, null, null, null);
if (cursor != null && cursor.moveToFirst()) {
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
fileName = cursor.getString(column_index);
if (!fileName.startsWith("/mnt")) {
fileName = "/mnt" + fileName;
}
cursor.close();
}
} else if (fileUrl.getScheme().compareTo("file") == 0) {
fileName = filePathUri.toString().replace("file://", "");
if (!fileName.startsWith("/mnt")) {
fileName += "/mnt";
}
}
}
return fileName;
}
Then I searched everywhere, and find out that it seems samsung changed the system, the TYPE_RINGTONE will not effect on samsung anymore, is it true ? How could fix this problem ?
Why samsung change it like this ? It's really ****ty for developers!
Could anyone help me ? Thank you!

You need the
<uses-permission android:name="android.permission.WRITE_SETTINGS"/>
Permission. Only grantable for System apps.

As I said, your app must be a system app (or a privileged app). Or else, adding this manifest to a normal app will not function at all and is useless.

Actually I think it's not the metter about the permission, the permission has been authorized, and the ringtone really changed into my ringtone on my device,
use these code you can see the default ringtone has changed after set.
private Uri getSystemDefaultRingtoneUri() {
return RingtoneManager.getActualDefaultRingtoneUri(this, RingtoneManager.TYPE_RINGTONE);//RingtoneManager.TYPE_ALL
}
Also use a different application to check the default ringtone, it's changed into the one that I choosen.
But in fact the the ring of incoming call from the speaker never changed.
So I think samsung use a different ringtone database or whatever.
Oh, and all kinds of random ringtong tools not work on S7edge.
I will try to figure it out when I rooted my s7edge.
And before this, I found some information about samsung ring of alarm, so I think the call maybe the same reason, http://bbs.anzhuo.cn/thread-938419-1-1.html
anyway, thanks for reply.

And here is the way for android 6.0.1 to ask the WRITE_SETTINGS permission
private boolean checkMyPermission(boolean isSecondTimeCheck) {
String dialogTitle = "need WRITE_SETTINGS permission";
if (isSecondTimeCheck) dialogTitle = "you deny the permission";
String btnTitle = "ok", if (isSecondTimeCheck) btnTitle = "try again";
if (Build.VERSION.SDK_INT >= 23) {
if (!Settings.System.canWrite(this)) {
new AlertDialog.Builder(mContext).setMessage(dialogTit le).setPositiveButton(btnTitle, new DialogInterface.OnClickListener() {
@override
public void onClick(DialogInterface dialog, int which) {
Intent intent = new Intent(Settings.ACTION_MANAGE_WRITE_SETTINGS, Uri.parse("package:" + getPackageName()));
startActivityForResult(intent, REQUEST_CODE_PERMISSION);
}
}).setNegativeButton("cancel", null).create().show();
return false;
}
return true;
} else {
int hasWriteContactsPermission = ContextCompat.checkSelfPermission(mContext, Manifest.permission.WRITE_SETTINGS);
if (hasWriteContactsPermission != PackageManager.PERMISSION_GRANTED) {
new AlertDialog.Builder(mContext).setMessage(dialogTit le).setPositiveButton(btnTitle, new DialogInterface.OnClickListener() {
@override
public void onClick(DialogInterface dialog, int which) {
Intent intent = new Intent(Settings.ACTION_MANAGE_WRITE_SETTINGS, Uri.parse("package:" + getPackageName()));
startActivityForResult(intent, REQUEST_CODE_PERMISSION);
}
}).setNegativeButton("cancel", null).create().show();
return false;
} else {
return true;
}

The permission has NOT been authorized. Please try to wrap your head around this. Your code is really messy.
https://github.com/android/platform_frameworks_base/blob/master/core/res/AndroidManifest.xml#L1597
Line 1600 states that you must have built the system through same firmware signature, "preinstalled" (priv-app), appop and pre-23 API
1595 states that it has a protection level of signature meaning that if the app isn't signed with the same signature as the ROM it won't be authorized to use that permission.
You can also try "pm grant YOUR_APP_NAME android.permission.WRITE_SETTINGS" in adb shell - and you will get an error saying it isn't a grantable permission.
Finally, if your app is a downloadable app from Play Store, this is the only caveat. Unless you request root to priv-app, THIS PERMISSION ISN'T GRANTED.
Java:
private boolean checkWriteSettingsPermissions() {
String permission = "android.permission.WRITE_SETTINGS";
int res = getContext().checkCallingOrSelfPermission(permission);
return (res == PackageManager.PERMISSION_GRANTED);
}
This is simple code that allows you to check whether your app is granted the permission.

Thank you for your patient.
1. I tried your code, and I was wrong about the permission, it says PERMISSION_DENIED. but I think this is not the problem for this question.
2. Did you tried my code ? The way that I asked for "WRITE_SETTINGS" is really work for ringtone, altho
Java:
private boolean checkWriteSettingsPermissions() {
String permission = "android.permission.WRITE_SETTINGS";
int res = getContext().checkCallingOrSelfPermission(permission);
return (res == PackageManager.PERMISSION_GRANTED);
}
said "PERMISSION_DENIED" , but it's really changed the ringtone ! If you not believe this, please try by yourself, and you can see from the setting - ring and vibrate - ringtone , you can see the result.
3. After several times try, I figure it out now... both way(manual and auto set by code "setMyRingtone()") of set the ringtone will work on the phone if have the permission of "Settings.System.canWrite(this)", but only work for the Ringtone of SIM 1, not work for SIM2. you can see the result form the setting page(only the ringtone for sim1 will change). if the ringtone still play the default ring of system, the problem probably is the metter of URI .
4. Before I post this thread, both way won't change the result of ringtone from the setting page of the phone, but as I said , you can see the result form another third part application.(this problem most probably is that I only use one SIM card at that time, did I put it into sim2? I don't know, already forget... but now if I put it into sim2 the ringtone form the setting page of the phone never change, but from the log of the code you can see the result is correct actually.)
5. Now the problem change into "How to create a standard URI and how to change the ringtone for SIM2". I will try to work on it.
6. Sorry for my pool English, and sorry for the "messy" code, I will improve it.
Anyway , thank you. you r the only one who helped me... Wish u luck.

I had the ringtone added on my MediaProvider but not set as the current one, I believe AOSP and TW deving is different.
When I mentioned "messy" I meant just copying and pasting the code into the forum, use
Code:
tags next time so it formats perfectly! :good::highfive:

Hey Have you found the solution..?
Hi,
i develop a map-app and want to implement google maps search
i get following build error
"error: package com.google.android.maps does not exist"
i develop under "android studio 3.1.3"
Hint for solution were appreciated
thanks
You need to add a reference to the maps package in build.gradle

i tested this https://stackoverflow.com/questions...le-android-maps-does-not-exist-android-studio
but without success
Can you post the content of your build.gradle file?

Apologies for the late reply, didn't get a notification from the thread.
Try removing the lines:
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.google.android.gmslay-services-maps:15.0.1
And add
implementation 'com.google.android.gmslay-services-maps:16.0.0'
If that doesn't work I'll draw up a demo app - this is a bit odd as I'm actually using maps in an app for my uni coursework and it's working fine
Edit: Also check that you have added the Google maven repo in the top level build.gradle file
hi,
i have still same error. i explained abov my purpose. i try this suggestion
https://stackoverflow.com/questions...ment-google-maps-search-by-address-in-android
and get this error.
and here is next purpose
https://stackoverflow.com/questions...-name-on-google-map-android?noredirect=1&lq=1
i don't know which one is better. i mean which one i can build without error.
hi jonny,
i have now a version it can work for me. but any thing is missed. can you pls add the missing parts.
thanks
