How to remove Handler from adapter

Question

I am using a function into an adapter and I added a Handler to do the refresh every 2s like below:

 final Handler refreshHandler = new Handler();
 Runnable runnable = new Runnable() {
     @Override
     public void run() {
         refreshHandler.postDelayed(this, 2000);
         myfunction();
     }
 };
 refreshHandler.postDelayed(runnable, 2000);

When I'm not into the fragment where I deploy the adapter the handler is always reloading.

So my question is, how to stop the handler every time I quit the fragment?

I think you should use the removeCallbacks(Runnable r) method.

That's how you put it in your code:

      final Handler refreshHandler = new Handler();
 Runnable runnable = new Runnable() {
     @Override
     public void run() {
         refreshHandler.postDelayed(this, 2000);
         myfunction();
     }
 };
 refreshHandler.postDelayed(runnable, 2000);


@Override
public void onDestroy () {

    refreshHandler.removeCallback(runnable);
    super.onDestroy ();

}

Something like that wherever you want. Hope you understand
