How to know if this thread is a UI Thread

Question

Is there any way on Android to know, if the thread running my code, is the UI Thread or not ? In swing there was SwingUtilities.isEventDispatchThread() to tell me

Answer 1

Yes, there is a way. Check the current thread object against main lopper's thread object. Main looper is always in the UI thread.

boolean isOnUiThread = Thread.currentThread() == Looper.getMainLooper().getThread();
