Change Boolean programmatically - Java for Android App Development

Hello.
i have been trying to work on my android app and enable / disable some activities in my app through a Broadcast
what i have added is
android:enable="@bool/activitiychange"
activitychange is in bools.xml set as true
but how do i add an option in the settingsprefernceactivity to set the boolean to False ?

This should work I think:
First define the boolean in like so:
Code:
private boolean test;
Now in your onCreate you can assign the test variable to the activitychange boolean like below (Note: you should also switch it to activityChange instead of activitychange, its proper naming of variables):
Code:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
...
test = getResources().getBoolean(R.bool.activityChange);
Then you can use the onSharedPreferenceChanged method to set the boolean to either true or false on a checkbox tick or untick event.

thanks but did it now in whole different way
Code:
public void togglePowerSaver(boolean status) {
PackageManager pm = getPackageManager();
if (status == true ) {
pm.setComponentEnabledSetting(new ComponentName(this, MainActivity.class),
PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);
Intent startMain = new Intent(Intent.ACTION_MAIN);
startMain.addCategory(Intent.CATEGORY_HOME);
startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startMain.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
startMain.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(startMain);
} else if (status == false ) {
pm.setComponentEnabledSetting(new ComponentName(this, MainActivity.class),
PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
Intent startMain = new Intent(Intent.ACTION_MAIN);
startMain.addCategory(Intent.CATEGORY_HOME);
startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startMain.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
startMain.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(startMain);
}
}
and for checkbox i used this
Code:
final CheckBoxPreference checkboxPref = (CheckBoxPreference) getPreferenceManager().findPreference("poweronoffPref");
checkboxPref.setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {
public boolean onPreferenceChange(Preference preference, Object newValue) {
if (newValue.toString().equals("true")) {
togglePowerSaver(true);
} else {
togglePowerSaver(false);
}
return true;
}
});
and worked
different way but worked
found this 20 minutes after post
only issue i currently have is that
its launcher
Code:
android:label="@string/app_name"
android:stateNotNeeded="true"
android:excludeFromRecents="true"
android:launchMode="singleTask"
android:theme="@style/SpaceTheme" >
and when i enter the launcher settings and disable the mainactivity ( launcher part )
and press back button it fcs. this is obvious because well the mainactivity is now gone.
is there a fix for this or bypass?

[Q][SOLVED] PreferenceActivity as AppWidget Config

I have been using a hand built ListActivity as my AppWidget config Activity but to be honest it looks ****ty and doesnt fit in with the rest of the app. So i wanted to transition over to a PreferenceActivity. i made a stub of a PreferenceActivity that launches the layout just fine when it is the main activity. but when i try to change from my ListActivity to my PreferenceAcitivity i get no launching of PreferenceActivity when i launch my widget. all i get is my widget.
i did a refactoring of my xml files to change the instances of my ListActivity (GITextConfig) to my PreferenceActivity (GITextPreferences).
how can i use a PreferenceActivity as my config?
do i need to have a dummy Activity be the config with a button to launch the PreferenceActivity? cause that works just fine. its lame and shouldnt be that way... nvm that does not work... i just cant get a prefs activity to run from an appwidget
anyone? this is quite annoying... i know it can be done as other widgets like gmail unread count does this. at least it appears to have a preferenceactivity as the configuration
got it to work. i dont know what i was doing before but i think i had a little too much of a stub for it to work. after i implemented the appwidget id verification and created my PreferenceManger and overode the onBackPressed() method it seems to work.... happy and confused.
Code:
public class GITextPreferences extends PreferenceActivity {
private int mAppWidgetId = AppWidgetManager.INVALID_APPWIDGET_ID;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
PreferenceManager localPrefs = getPreferenceManager();
localPrefs.setSharedPreferencesName("GITC_Prefs");
addPreferencesFromResource(R.xml.gitc_preferences);
// Find the widget id from the intent.
Intent intent = getIntent();
Bundle extras = intent.getExtras();
if (extras != null) {
mAppWidgetId = extras.getInt(AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID);
}
// If they gave us an intent without the widget id, just bail.
if (mAppWidgetId == AppWidgetManager.INVALID_APPWIDGET_ID) {
finish();
}
}
@Override
public void onBackPressed() {
// Make sure we pass back the original appWidgetId
Intent resultValue = new Intent();
resultValue.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, mAppWidgetId);
setResult(RESULT_OK, resultValue);
finish();
}
}

[Q] Using Split Action in android

Hi!
My self Raj, i have a problem when using the split action in my application.
i am doing an E-Menu for an restaurant. i list out all available category in major listview if the user click on the item of major list it should display all available minor items of its in behind of the Major listview.
I found one solution in Google it is possible by using split action.
Can anyone guide me / give some sample i may know about it..,
I am waiting for your guide.,
Have A Happy Day..,
Thanks to all..,
Simply add the following line to your <activity> or <application> tag in your AndroidManifest :
Code:
uiOptions="splitActionBarWhenNarrow"
EDIT : As a side note, it seems you want the split actionbar to be displayed only after the user clicked something, in that use case, the Contextual ActionBar seems more suited.
To use it, simply define your actionbar items in a menu.xml just like the normal actionbar, then in your java code use something like :
Code:
private ActionMode.Callback mActionModeCallback = new ActionMode.Callback() {
@Override
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
MenuInflater inflater = mode.getMenuInflater();
inflater.inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
return false;
}
@Override
public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
switch (item.getItemId()) {
case R.id.menu_item1:
//do something
mode.finish();
return true;
case R.id.menu_item2:
// do something else
mode.finish();
return true;
case R.id.menu_item3:
// etc....
mode.finish();
return true;
default:
return false;
}
}
@Override
public void onDestroyActionMode(ActionMode mode) {
mActionMode = null;
}
And in the onClickListener() of the component that triggers the contextual ActionBar, call it like that :
Code:
if (mActionMode != null)
// Do nothing
else
mActionMode = startActionMode(mActionModeCallback);
You might want to use the ActionBarSherlock Library in order to keep compatibility with gingerbread/froyo

Enabling selection in textview

I am using this android:textIsSelectable and still gets the error:
Code:
TextView does not support text selection. Action mode cancelled.
Can any one please tell me what I might be doing wrong?

Please post the code and also the AP version you are testing the app cant say anything without that
I believe testIsSelectable for TextViews was introduced in Honeycomb, if you want to be able to mimic that feature with lower versions of Android, here's a little workaround :
Use an EditText instead of your TextView and set android:textIsSelectable to false
In your activity's java code, override onLongClickListener and set the EditText to selectable in this method, something like this :
Code:
public class yourClass extends Activity implements onLongClickListener {
EditText yourFakeTextView;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.whatever);
yourFakeTextView = (EditText) findViewById(R.id.editText1);
yourFakeTextView.setOnLongClickListener(this);
}
@Override
public boolean onLongClick(View v) {
switch (v.getId()) {
case R.id.editText1:
yourFakeTextView.setTextIsSelectable(true);
break;
default:
return;
}
return false;
}
}
This will make the EditText look like a regular TextView, and when the user long-clicks it, it will allow him to select the text (just like if it was a normal, selectable TextView).
Hope this helps.
I want to enable this feature on ICS and upper version of android. I am testing this on an ics device. There is something which is messed up. I will post the code as soon as I reach home!

[Q] Dialog out of Activity

Hello app developers!
I have got serious problem. Every time I call alertdialogs or other dialogs I see them only in activity. But my app needs to show this dialog when user works on phone, that's why it must be shown out of activity. Any ideas?

You cannot do this. There is simply no feature for that. I have had that problem, too.
Use a Notification or a Toast message.
There is a work-around for this. If you run a service, you can technically launch an activity that can resemble this.
I have an app that uses a broadcast receiver to listen for the events I want to alert my user to. I created a custom layout for my alert dialog and then when the event happens, my broadcast receiver calls the activity.

Yes, great idea. Launch a transparent Activity and start a dialog. Set an onDismissListener and close the app when the dialog is closed.

If I start a transparent activity user can't see that it was started as I understand. Can you give code for broadcast receiver maybe I misunderstand something
The broadcast receiver is just the mechanism I use to launch the activity. It is a mere intent that I start from it. Below is the class I use for my alertdialog. You won't be able to cut and paste because I also created my own class to dismiss the activity.
Code:
public class SilentDialog extends TimedActivity implements OnTouchListener{

this.requestWindowFeature(Window.FEATURE_NO_TITLE);

this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
super.onCreate(savedInstanceState);
showAlert();
}

//reset idle timer
// put this here so that the touching of empty space is captured too
// it seems that LinearLayout doesn't trigger a MotionEvent.ACTION_UP or MotionEvent.ACTION_MOVE
if (actionPerformed == MotionEvent.ACTION_DOWN)
{

spin.setVisibility(8);

rate.setVisibility(8);

text.setText("ButlerSMS has detected the ringer mode has changed to silent. " +
"\n\n Would you like ButlerSMS to turn on?");

}

I understood everything except the way how app switch between position before signal came and required activity with alert dialog in it. As I see this code initialize activity and alert dialog but don't contain switching that I need
Are you asking how I call the dialog? If so, a simple intent from a broadcast receiver.
Code:
Intent i = new Intent(context, SilentDialog.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
I would use the AlertDialog.Builder class for compatibility.
Why not use a notification, I think that is more elegant.
Code:
public class InstalledReceiver extends BroadcastReceiver {
private NotificationManager mNotificationManager ;
[user=439709]@override[/user]
public void onReceive(Context context, Intent intent) {
if (BaseActivity.DEBUG) System.out.println("Received Broadcast");
Boolean update = intent.getBooleanExtra(Intent.EXTRA_REPLACING, false);
mNotificationManager = (NotificationManager) context.getSystemService("notification");
SharedPreferences getPrefs = PreferenceManager.getDefaultSharedPreferences(context);
Boolean disabledNotifications = getPrefs.getBoolean("disableNotifications", false);
if (!disabledNotifications && !update) makeNotification(context);
}
private void makeNotification(Context context) {
CharSequence label = context.getString(R.string.labelNotify);
CharSequence text = context.getString(R.string.textNotify);
CharSequence full = context.getString(R.string.fullNotify);
final Notification notification = new Notification(R.drawable.ic_launcher,text,System.currentTimeMillis());
notification.setLatestEventInfo(context,label,full,null);
notification.defaults = Notification.DEFAULT_ALL;
mNotificationManager.notify( 0, notification);
}
}

I agree, but if he wants to use a dialog, we help him to make one.
The bad thing about the dialog is that it will interrupt whatever the user is doing. This could be very annoying. And who wants to use an app which has annoying popups?

When I use this code activity don't shows when I am out of application. For example Handcent SMS when SMS comes to user shows up a great dialog over all windows. My aim is the same thing

If you use another layout, is the Activity opened?
Is the "Here" written to the log? Is there any Error message?
And I recommend configuring the AlertDialog within the AlertDialog.Builder: http://www.mkyong.com/android/android-alert-dialog-example/
(However, I guess that it will not solve your problem.)

[Q] onSaveInstanceState

I'm new to android app development
Facing an issue:
Data (String values) lost while changing screen orientation
I googled about it and found it can be handled by onSaveInstanceState()
But didn't get how to use that in the java file
Can someone clear it to me?
static final String STATE_SCORE = "playerScore";
static final String STATE_LEVEL = "playerLevel";
...
@override
public void onSaveInstanceState(Bundle savedInstanceState) {
// Save the user's current game state
savedInstanceState.putInt(STATE_SCORE, mCurrentScore);
savedInstanceState.putInt(STATE_LEVEL, mCurrentLevel);
// Always call the superclass so it can save the view hierarchy state
super.onSaveInstanceState(savedInstanceState);
}
 @override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); // Always call the superclass first
// Check whether we're recreating a previously destroyed instance
if (savedInstanceState != null) {
// Restore value of members from saved state
mCurrentScore = savedInstanceState.getInt(STATE_SCORE);
mCurrentLevel = savedInstanceState.getInt(STATE_LEVEL);
} else {
// Probably initialize members with default values for a new instance
}

If It s so important then save it as file
Or save it as temporary data to Bundle
Code:
Bundle.putExtra("name", Data);
