I am using handler.postDelayed() to create a waiting period before the next stage of my app takes place. During the wait period I am displaying a dialog with progress bar and cancel button.

My problem is I can't find a way to cancel the postDelayed task before the time elapses.


I do this to post a delayed runnable:

myHandler.postDelayed(myRunnable, SPLASH_DISPLAY_LENGTH); 

And this to remove it: myHandler.removeCallbacks(myRunnable);

How to cancel handler.postDelayed?, I do this to cancel postDelays, per the Android: removeCallbacks removes any pending posts of Runnable r that are in the message queue. If you don't want to keep a reference of the runnable, you could simply call: handler. removeCallbacksAndMessages(null); In case you do have multiple inner/anonymous runnables passed to same handler, and you want to cancel all at same event use. handler.removeCallbacksAndMessages(null); As per documentation, Remove any pending posts of callbacks and sent messages whose obj is token. If token is null, all callbacks and messages will be removed.

Another way is to handle the Runnable itself:

Runnable r = new Runnable {

It worked for me when I called CancelCallBacks(this) inside the post delayed runnable by handing it via a boolean

Runnable runnable = new Runnable(){
    @Override
    public void run() {
        Log.e("HANDLER", "run: Outside Runnable");
        if (IsRecording) {
            Log.e("HANDLER", "run: Runnable");
            handler.postDelayed(this, 2000);
        }else{
            handler.removeCallbacks(this);
        }
    }
};

Here is a class providing a cancel method for a delayed action

public class DelayedAction {

private Handler _handler;
private Runnable _runnable;

/**
 * Constructor
 * @param runnable The runnable
 * @param delay The delay (in milli sec) to wait before running the runnable
 */
public DelayedAction(Runnable runnable, long delay) {

Android Handler, In this video we will learn, how to execute a piece of code by passing a Runnable to a Handler Duration: 5:53 Posted: Jan 4, 2018 The Looper in the Android system manages the message queue and message loop of the thread. Looper.myLooper() method can return current thread’s Looper object, and Looper.getMainLooper() method will return current process’s main thread’s Looper object. 1. Android Child Thread Example. Now let us look at below code first.


Delay and Repeat Code Execution with Handler PostDelayed , postDelayed(this,1000); } }; handler.post(run); // To stop this runnable //handler. way to time","Java utils Timer"); } },5000,1000); //To stop //timer.cancel()  Schedule and process messages; Schedule and execute Runnables; Perform its actions on a different Thread that a Handler was created in; Being reused as many times as needed; Pretty nice stuff to begin with.
