How To Detect Notification Center Is Pulled Down/up In Android

Since onPause and onResume is not called when the notification overlay is pulled down in Android L, is there a way for my Activity to update accordingly after the Notification Cent

Solution 1:

You can utilize your Activity's onWindowFocusChanged callback to detect when notification is pulled down/up while your Activity is running:

@OverridepublicvoidonWindowFocusChanged(boolean hasFocus) {
    if (hasFocus) { 
      // notification is pulled up
    } else { 
      // notification is pulled down 
    }
    super.onWindowFocusChanged(hasFocus);
}

Solution 2:

I'm am afraid there is still no way to detect if the Notification Center is pulled pulled down.

You may want to reconsider if you need to implement a different behaviour when such an event occurs - maybe you'll find out it's not even necessary.

Solution 3:

You can add a receiver for the android.net.conn.CONNECTIVITY_CHANGE action. You'll be notified if the user changed the setting (but also for other types of network changes, so you'll need to handle these).
