How can avoid firing multiple times an onClick event when the user presses the button more than once really quick?

Question

In Android, if the user presses a button multiple times really quick the onClick event is fired multiple times.. which kind of makes sense.

If the onClick method starts a new Activity, the user can open the same Activity multiple times and each instance of the Activity will be piled on top of the stack.

I usually disable the button inside the onClick method (associated to the button) and enable it again a couple of seconds after with the use of a Handler and postDelay.

I don't really like doing it in this way so is there another way of approaching this problem in a more clean way?

Answer 1

In the Activities case you could also pass an extra for your Intent:

intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

or

intent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);

to avoid multiple starts.

Other way is to have a dummy boolean while you're managing the click that prevents multiple clicks.

UPDATE with example:

boolean processingClick = false;
Button b = new Button();
b.setOnClickListener(new View.OnClickListener() {
    @Override public void onClick(View v) {
        if (!processingClick) {
            processingClick = true;

            //your code here

            processingClick = false;
        }
    }
});
