Determine addAction click for Android notifications

问题:

I'm trying to use the new notifications interface. I've added 3 buttons to the notifications, and I want to save something to my database once each of them is clicked.

The notification itself works well and is shown when called, I just don't know how to capture each of the three different button clicks.

I'm using a BroadcastReceiver to catch the clicks, but I don't know how to tell which button was clicked.

This is the code of AddAction(I've excluded the rest of the notification, as its working well) -

    //Yes intent     Intent yesReceive = new Intent();       yesReceive.setAction(CUSTOM_INTENT);     Bundle yesBundle = new Bundle();                 yesBundle.putInt("userAnswer", 1);//This is the value I want to pass     yesReceive.putExtras(yesBundle);     PendingIntent pendingIntentYes = PendingIntent.getBroadcast(this, 12345, yesReceive, PendingIntent.FLAG_UPDATE_CURRENT);     mBuilder.addAction(R.drawable.calendar_v, "Yes", pendingIntentYes);      //Maybe intent     Intent maybeReceive = new Intent();       maybeReceive.setAction(CUSTOM_INTENT);     Bundle maybeBundle = new Bundle();                 maybeBundle.putInt("userAnswer", 3);//This is the value I want to pass     maybeReceive.putExtras(maybeBundle);     PendingIntent pendingIntentMaybe = PendingIntent.getBroadcast(this, 12345, maybeReceive, PendingIntent.FLAG_UPDATE_CURRENT);     mBuilder.addAction(R.drawable.calendar_question, "Partly", pendingIntentMaybe);      //No intent     Intent noReceive = new Intent();       noReceive.setAction(CUSTOM_INTENT);     Bundle noBundle = new Bundle();                 noBundle.putInt("userAnswer", 2);//This is the value I want to pass     noReceive.putExtras(noBundle);     PendingIntent pendingIntentNo = PendingIntent.getBroadcast(this, 12345, noReceive, PendingIntent.FLAG_UPDATE_CURRENT);     mBuilder.addAction(R.drawable.calendar_x, "No", pendingIntentNo); 

This is the code of the BroadcastReceiver-

 public class AlarmReceiver extends BroadcastReceiver {  @Override public void onReceive(Context context, Intent intent) {     Log.v("shuffTest","I Arrived!!!!");      //Toast.makeText(context, "Alarm worked!!", Toast.LENGTH_LONG).show();      Bundle answerBundle = intent.getExtras();     int userAnswer = answerBundle.getInt("userAnswer");     if(userAnswer == 1)     {         Log.v("shuffTest","Pressed YES");     }     else if(userAnswer == 2)     {         Log.v("shuffTest","Pressed NO");     }     else if(userAnswer == 3)     {         Log.v("shuffTest","Pressed MAYBE");     }  }            } 

I've registered the BroadcastReceiver in the Manifest. Also, I want to mention that the BroadcastReceiver is called when I click one of the buttons in the notification, but the intent always includes an extra of '2'.

This is the notifcation iteslf -

It's because you're using FLAG_UPDATE_CURRENT with Intents that have the same action

From the docs:

if the described PendingIntent already exists, then keep it but its replace its extra data with what is in this new Intent.

When you specify pendingIntentMaybe and pendingIntentNo, the system uses the PendingIntent created for pendingIntentYes, but it overwrites the extras. Thus, all three variables refer to the same object, and the last extras specified were for pendingIntentNo.

You should specify an alternative action for each Intent. You can still have one BroadcastReceiver, and just have it intercept all three actions. This would be less confusing semantically as well :)

Your Notification poster:

//Yes intent Intent yesReceive = new Intent();   yesReceive.setAction(YES_ACTION); PendingIntent pendingIntentYes = PendingIntent.getBroadcast(this, 12345, yesReceive, PendingIntent.FLAG_UPDATE_CURRENT); mBuilder.addAction(R.drawable.calendar_v, "Yes", pendingIntentYes);  //Maybe intent Intent maybeReceive = new Intent();   maybeReceive.setAction(MAYBE_ACTION); PendingIntent pendingIntentMaybe = PendingIntent.getBroadcast(this, 12345, maybeReceive, PendingIntent.FLAG_UPDATE_CURRENT); mBuilder.addAction(R.drawable.calendar_question, "Partly", pendingIntentMaybe);  //No intent Intent noReceive = new Intent();   noReceive.setAction(NO_ACTION); PendingIntent pendingIntentNo = PendingIntent.getBroadcast(this, 12345, noReceive, PendingIntent.FLAG_UPDATE_CURRENT); mBuilder.addAction(R.drawable.calendar_x, "No", pendingIntentNo); 

Your receiver:

@Override public void onReceive(Context context, Intent intent) {     String action = intent.getAction();      if(YES_ACTION.equals(action)) {         Log.v("shuffTest","Pressed YES");     } else if(MAYBE_ACTION.equals(action)) {         Log.v("shuffTest","Pressed NO");     } else if(NO_ACTION.equals(action)) {         Log.v("shuffTest","Pressed MAYBE");     } }

in My case it worked for me after adding the intent-filter

 <receiver android:name=".AlarmReceiver">       <intent-filter>            <action android:name="YES_ACTION"/>            <action android:name="NO_ACTION"/>            <action android:name="MAYBE_ACTION"/>       </intent-filter>   </receiver>

STEP_BY_STEP

Step 1

public void noto2() // paste in activity {     Notification.Builder notif;     NotificationManager nm;     notif = new Notification.Builder(getApplicationContext());     notif.setSmallIcon(R.drawable.back_dialog);     notif.setContentTitle("");     Uri path = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);     notif.setSound(path);     nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);      Intent yesReceive = new Intent();     yesReceive.setAction(AppConstant.YES_ACTION);     PendingIntent pendingIntentYes = PendingIntent.getBroadcast(this, 12345, yesReceive, PendingIntent.FLAG_UPDATE_CURRENT);     notif.addAction(R.drawable.back_dialog, "Yes", pendingIntentYes);       Intent yesReceive2 = new Intent();     yesReceive2.setAction(AppConstant.STOP_ACTION);     PendingIntent pendingIntentYes2 = PendingIntent.getBroadcast(this, 12345, yesReceive2, PendingIntent.FLAG_UPDATE_CURRENT);     notif.addAction(R.drawable.back_dialog, "No", pendingIntentYes2);        nm.notify(10, notif.getNotification()); } 

Step 1.5

I created a global class AppConstant

 public class AppConstant     {   public static final String YES_ACTION = "YES_ACTION";   public static final String STOP_ACTION = "STOP_ACTION";   }  

Step 2:

 public class NotificationReceiver extends BroadcastReceiver {  @Override public void onReceive(Context context, Intent intent) {     // TODO Auto-generated method stub     String action = intent.getAction();     if (AppConstant.YES_ACTION.equals(action)) {         Toast.makeText(context, "YES CALLED", Toast.LENGTH_SHORT).show();     }     else  if (AppConstant.STOP_ACTION.equals(action)) {         Toast.makeText(context, "STOP CALLED", Toast.LENGTH_SHORT).show();     } } 

}

Step 3

 <receiver android:name=".NotificationReceiver">         <intent-filter>             <action android:name="YES_ACTION"/>             <action android:name="STOP_ACTION"/>          </intent-filter>     </receiver> 

回答4:

here YES_ACTION must be yourfullpackagename.YES

like

private static final String YES_ACTION = "com.example.packagename.YES"; 

likewise you can use NO_ACTION or MAYBE_ACTION

In BroadcastReceiver you have to use same YES_ACTION as declared above,

means in BroadcastReceiver class you can check for custom Broadcast by following

public class NotificationReceiver extends BroadcastReceiver {  private static final String YES_ACTION = "com.example.packagename.YES"; @Override public void onReceive(Context context, Intent intent) {     // TODO Auto-generated method stub     String action = intent.getAction();     if(YES_ACTION.equals(action)) {         Toast.makeText(context, "CALLED", Toast.LENGTH_SHORT).show();     } } 

}

note : instead of YES in YES_ACTION string you can use other word also.
