Handle three buttons click event in custom notification in android

问题

I have a custom notification with three buttons ("ok", "cancel", "later") I can catch click event only when there is one button, but with the three buttons i can't know which button of them is clicked. My question is "How to know which button is clicked?"

// I use this code in My "createNotification" function to add event to buttons
Intent intent = new Intent(Context.NOTIFICATION_SERVICE);
PendingIntent pendinghomeIntent = 
            PendingIntent.getBroadcast(getBaseContext(), 0, intent, 0);
notificationView.setOnClickPendingIntent(R.id.okButt, pendingrecentAppIntent);
notificationView.setOnClickPendingIntent(R.id.cancelButt, pendingrecentAppIntent);
notificationView.setOnClickPendingIntent(R.id.laterButt, pendingrecentAppIntent);

I craeted a service to register and unregister the broadcast receiver and this is done perfectly in case of one button. With the three buttons, when i click on each of them the same result (which is implemeneted in onReceive function) is happened, but i want for each of them a different result.

Please help me, thanks in advance

You need to use separate PendingIntents(made from Intents with differecnt actions) for every button. Later in onReceive() you just check action of incoming Intent & execute different code depending on that.

As Sam said, "You need to use separate PendingIntents(made from Intents with different actions) for every button." I found that i must use separate PendingIntents for every button but the concept of "different actions" not worked for me. I used the second parameter of setOnClickPendingIntent to distinguish between the three PendingIntents with use FLAG_UPDATE_CURRENT for the fourth parameter. My code is

Intent homeIntent = new Intent(Context.NOTIFICATION_SERVICE);
    Bundle yesBundle = new Bundle();            
    yesBundle.putInt("userAnswer", 1);
    homeIntent.putExtras(yesBundle);
    PendingIntent pendinghomeIntent = 
            PendingIntent.getBroadcast(getBaseContext(), 0, homeIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    notificationView.setOnClickPendingIntent(R.id.homeButt, pendinghomeIntent);

    Intent recentAppIntent = new Intent(Context.NOTIFICATION_SERVICE);
    Bundle recentAppBundle = new Bundle();   
    recentAppBundle.putInt("userAnswer", 2);
    recentAppIntent.putExtras(recentAppBundle);
    PendingIntent pendingrecentAppIntent = 
            PendingIntent.getBroadcast(getBaseContext(), 1, recentAppIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    notificationView.setOnClickPendingIntent(R.id.recentAppButt, pendingrecentAppIntent);

    Intent settingsIntent = new Intent(Context.NOTIFICATION_SERVICE);
    Bundle settingsBundle = new Bundle();            
    settingsBundle.putInt("userAnswer", 3);
    settingsIntent.putExtras(settingsBundle);
    PendingIntent pendingsettingsIntent = 
            PendingIntent.getBroadcast(getBaseContext(), 2, settingsIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    notificationView.setOnClickPendingIntent(R.id.settingsButt, pendingsettingsIntent);
    notificationManager.notify(1, notification);

and onReceive() code is

public void onReceive(Context context, Intent intent) {
        Bundle answerBundle = intent.getExtras();
        int userAnswer = answerBundle.getInt("userAnswer");
        if(userAnswer == 1) {
            Log.v("shuffTest","Pressed Home");
        }else if(userAnswer == 2) {
            Log.v("shuffTest","Pressed Recent App");
        }else if(userAnswer == 3) {
            Log.v("shuffTest","Pressed Settings");
        }
    }

before two days i was stuck on same problem,i found that i was not specifiying seperate action for every pending intent, like

  Intent recentApIntent = new Intent(Context.NOTIFICATION_SERVICE);
   recentApIntent.setAction("Action 1"); 
    Bundle recentAppBundle = new Bundle();   
    recentAppBundle.putInt("userAnswer", 2);
    recentAppIntent.putExtras(recentAppBundle);
    PendingIntent pendingrecentAppIntent = 
            PendingIntent.getBroadcast(getBaseContext(), 1, recentAppIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    notificationView.setOnClickPendingIntent(R.id.recentAppButt, pendingrecentAppIntent);

Similarly separate each intent with action and when receive broadcast identify intent.getAction() and perform task
