Question

I have a custom notification with a button. To set the notification and use the event OnClick on my button I\'ve used this code:

//Notification and intent of

You need to create Service to detect on Click event: For example Create NotificationIntentService.class and put below code:

public class NotificationIntentService extends IntentService {

    /**
     * Creates an IntentService.  Invoked by your subclass's constructor.
     */
    public NotificationIntentService() {
        super("notificationIntentService");
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        switch (intent.getAction()) {
            case "left":
                android.os.Handler leftHandler = new android.os.Handler(Looper.getMainLooper());
                leftHandler.post(new Runnable() {
                    @Override
                    public void run() {
                        Toast.makeText(getBaseContext(),
                                "You clicked the left button", Toast.LENGTH_LONG).show();
                    }
                });
                break;
            case "right":
                android.os.Handler rightHandler = new android.os.Handler(Looper.getMainLooper());
                rightHandler.post(new Runnable() {
                    @Override
                    public void run() {
                        Toast.makeText(getBaseContext(), "You clicked the right button", Toast.LENGTH_LONG).show();
                    }
                });
                break;
        }
    }
}

Add this metod to your activity:

private void sendNotification() {

    RemoteViews expandedView = new RemoteViews(getPackageName(), R.layout.view_expanded_notification);
    expandedView.setTextViewText(R.id.timestamp, DateUtils.formatDateTime(this, System.currentTimeMillis(), DateUtils.FORMAT_SHOW_TIME));
    expandedView.setTextViewText(R.id.notification_message, mEditText.getText());
    // adding action to left button
    Intent leftIntent = new Intent(this, NotificationIntentService.class);
    leftIntent.setAction("left");
    expandedView.setOnClickPendingIntent(R.id.left_button, PendingIntent.getService(this, 0, leftIntent, PendingIntent.FLAG_UPDATE_CURRENT));
    // adding action to right button
    Intent rightIntent = new Intent(this, NotificationIntentService.class);
    rightIntent.setAction("right");
    expandedView.setOnClickPendingIntent(R.id.right_button, PendingIntent.getService(this, 1, rightIntent, PendingIntent.FLAG_UPDATE_CURRENT));

    RemoteViews collapsedView = new RemoteViews(getPackageName(), R.layout.view_collapsed_notification);
    collapsedView.setTextViewText(R.id.timestamp, DateUtils.formatDateTime(this, System.currentTimeMillis(), DateUtils.FORMAT_SHOW_TIME));

    NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
            // these are the three things a NotificationCompat.Builder object requires at a minimum
            .setSmallIcon(R.drawable.ic_pawprint)
            .setContentTitle(NOTIFICATION_TITLE)
            .setContentText(CONTENT_TEXT)
            // notification will be dismissed when tapped
            .setAutoCancel(true)
            // tapping notification will open MainActivity
            .setContentIntent(PendingIntent.getActivity(this, 0, new Intent(this, MainActivity.class), 0))
            // setting the custom collapsed and expanded views
            .setCustomContentView(collapsedView)
            .setCustomBigContentView(expandedView)
            // setting style to DecoratedCustomViewStyle() is necessary for custom views to display
            .setStyle(new android.support.v7.app.NotificationCompat.DecoratedCustomViewStyle());

    // retrieves android.app.NotificationManager
    NotificationManager notificationManager = (android.app.NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    notificationManager.notify(0, builder.build());
}
