Avoid button multiple rapid clicks

Question

I have a problem with my app that if the user clicks the button multiple times quickly, then multiple events are generated before even my dialog holding the button disappear

Answer 1

Here is a pretty simple solution, which can be used with lambdas:

view.setOnClickListener(new DebounceClickListener(v -> this::doSomething));

Here is the copy/paste ready snippet:

public class DebounceClickListener implements View.OnClickListener {

    private static final long DEBOUNCE_INTERVAL_DEFAULT = 500;
    private long debounceInterval;
    private long lastClickTime;
    private View.OnClickListener clickListener;

    public DebounceClickListener(final View.OnClickListener clickListener) {
        this(clickListener, DEBOUNCE_INTERVAL_DEFAULT);
    }

    public DebounceClickListener(final View.OnClickListener clickListener, final long debounceInterval) {
        this.clickListener = clickListener;
        this.debounceInterval = debounceInterval;
    }

    @Override
    public void onClick(final View v) {
        if ((SystemClock.elapsedRealtime() - lastClickTime) < debounceInterval) {
            return;
        }
        lastClickTime = SystemClock.elapsedRealtime();
        clickListener.onClick(v);
    }
}

Enjoy!
