title: Android: Keep notifications open on button press
body: <p>I have a <code>NotificationCompat.Builder</code> which has a custom <code>RemoteView</code> set via its <code>setContent</code> method. This <code>RemoteView</code> contains, among other things, a couple of buttons.</p>
  
  <p>I attach a <code>PendingIntent</code> to the button via
  <code>notificationView.setOnClickPendingIntent(R.id.notification_button_plusone, pIntentPlusOne);</code></p>
  
  <p>The problem is that I don't want the Notification Drawer to dissapear after a button is pressed, but keep it open, so that I can press the <code>R.id.notification_button_plusone</code>-Button multiple times without needing to pull down the Notification Drawer for each button press.</p>
  
  <p>Also, I might want to press the +1 button (unrelated to Google Plus, just to add weight to something) multiple times, then press a star-button and finally a share button in the same notification. The button press on the share button should close the notification drawer, all other buttons should keep it open.</p>
  
  <p>How can I do that? I see that the App "Power Toggles" is able to do that, that's the behaviour I want.</p>
