Adding button action in custom notification

问题

I have made custom notification and there is a button in that, I want to perform two different functionalities on notification and button click. I look at many links but couldn\'t find the way to add button listener.

Can anyone help. Here is my code. Thanks a lot.

 private void startNotification() {
    Intent intent;
    PendingIntent pIntent;
    RemoteViews remoteViews = new RemoteViews(getPackageName(),
            R.layout.mynotification);

    Context context = getApplicationContext();
    NotificationCompat.Builder builder = new NotificationCompat.Builder(
            this).setSmallIcon(R.drawable.ic_launcher).setContent(
            remoteViews);

    if (hasFlash) {
        intent = new Intent(context, FlashLight.class);
        pIntent = PendingIntent.getActivity(context, 1, intent, 0);
    } else {
        intent = new Intent(context, BlankWhiteActivity.class);
        pIntent = PendingIntent.getActivity(context, 1, intent, 0);
    }
    builder.setContentIntent(pIntent);
    NotificationManager mNotificationManager = (NotificationManager)      getSystemService(Context.NOTIFICATION_SERVICE);

    Notification notif = builder.setContentTitle(\"Flashlight\")
            .setContentText(\"Lighten your world!!!\").build();
    mNotificationManager.notify(1, notif);

    remoteViews.setOnClickPendingIntent(R.id.closeOnFlash, pIntent);

}

I have passed the button id (closeOnFlash) in setOnClickPendingIntent don\'t know why its not working.

And here is my xml:

<?xml version=\"1.0\" encoding=\"UTF-8\"?>
 <LinearLayout xmlns:android=\"http://schemas.android.com/apk/res/android\"
 android:layout_width=\"fill_parent\"
 android:layout_height=\"fill_parent\"
 android:gravity=\"center\"
 android:orientation=\"horizontal\"
 android:weightSum=\"100\" >

<ImageView
    android:id=\"@+id/notifiation_image\"
    android:layout_width=\"0dp\"
    android:layout_height=\"wrap_content\"
    android:layout_weight=\"30\"
    android:contentDescription=\"@string/appImage\"
    android:src=\"@drawable/ic_launcher\" />

<TextView
    android:id=\"@+id/appName\"
    android:layout_width=\"wrap_content\"
    android:layout_height=\"wrap_content\"
    android:layout_weight=\"50\"
    android:gravity=\"center\"
    android:text=\"@string/flashLightOn\"
    android:textAppearance=\"?android:attr/textAppearanceMedium\" />

<Button
    android:id=\"@+id/closeOnFlash\"
    android:layout_width=\"wrap_content\"
    android:layout_height=\"wrap_content\"
    android:layout_weight=\"20\"
    android:text=\"@string/close\" />

Start notification as:

private void startNotification(){
    String ns = Context.NOTIFICATION_SERVICE;
    NotificationManager notificationManager = 
            (NotificationManager) getSystemService(ns);

    Notification notification = new Notification(R.drawable.ic_launcher, null, 
            System.currentTimeMillis());

    RemoteViews notificationView = new RemoteViews(getPackageName(),
            R.layout.mynotification);

    //the intent that is started when the notification is clicked (works)
    Intent notificationIntent = new Intent(this, FlashLight.class);
    PendingIntent pendingNotificationIntent = PendingIntent.getActivity(this, 0, 
            notificationIntent, 0);

    notification.contentView = notificationView;
    notification.contentIntent = pendingNotificationIntent;
    notification.flags |= Notification.FLAG_NO_CLEAR;

    //this is the intent that is supposed to be called when the 
    //button is clicked
    Intent switchIntent = new Intent(this, switchButtonListener.class);
    PendingIntent pendingSwitchIntent = PendingIntent.getBroadcast(this, 0, 
            switchIntent, 0);

    notificationView.setOnClickPendingIntent(R.id.closeOnFlash, 
            pendingSwitchIntent);

    notificationManager.notify(1, notification);
}


public static class switchButtonListener extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d("Here", "I am here");
        FlashOnOff flashLight;
        flashLight = new FlashOnOff();
        flashLight.flashLightOff();
        flashLight.releaseCamera();         
    }
}
