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's my version of the accepted answer. It is very similar, but doesn't try to store Views in a Map which I don't think is such a good idea. It also adds a wrap method that could be useful in many situations.

/**
 * Implementation of {@link OnClickListener} that ignores subsequent clicks that happen too quickly after the first one.

 * To use this class, implement {@link #onSingleClick(View)} instead of {@link OnClickListener#onClick(View)}.
 */
public abstract class OnSingleClickListener implements OnClickListener {
    private static final String TAG = OnSingleClickListener.class.getSimpleName();

    private static final long MIN_DELAY_MS = 500;

    private long mLastClickTime;

    @Override
    public final void onClick(View v) {
        long lastClickTime = mLastClickTime;
        long now = System.currentTimeMillis();
        mLastClickTime = now;
        if (now - lastClickTime < MIN_DELAY_MS) {
            // Too fast: ignore
            if (Config.LOGD) Log.d(TAG, "onClick Clicked too quickly: ignored");
        } else {
            // Register the click
            onSingleClick(v);
        }
    }

    /**
     * Called when a view has been clicked.
     * 
     * @param v The view that was clicked.
     */
    public abstract void onSingleClick(View v);

    /**
     * Wraps an {@link OnClickListener} into an {@link OnSingleClickListener}.

     * The argument's {@link OnClickListener#onClick(View)} method will be called when a single click is registered.
     * 
     * @param onClickListener The listener to wrap.
     * @return the wrapped listener.
     */
    public static OnClickListener wrap(final OnClickListener onClickListener) {
        return new OnSingleClickListener() {
            @Override
            public void onSingleClick(View v) {
                onClickListener.onClick(v);
            }
        };
    }
}
