android - How to cancel handler.postDelayed?

Question

What if I have handler.postDelayed thread already under execution and I need to cancel it?

Answer 1

I do this to cancel postDelays, per the Android: removeCallbacks removes any pending posts of Runnable r that are in the message queue.

handler.removeCallbacks(runnableRunner);

or use to remove all messages and callbacks

handler.removeCallbacksAndMessages(null);
