Answer 1

The up solution cannot work for multi click, i test it but failed.

So i suggest to use RxBinding with ProgressDialog.

You may want to consider not using a DoubleTap. It is not a normal Android behavior.

When I first started programming on the Android, I kept running into things that were really "hard" to do on the android. Over time, I've found that many of them were difficult because they were a pretty bad idea.

If you are porting an iOS app, or emulating an iOS app's behavior, you may want to consider converting the UI over to Android style behaviors and use a longPress or other 'androidy' gestures.

Well it is simple just override.

onClick method of OnClickListener

public abstract class DoubleClickListener implements View.OnClickListener {
private static final long DEFAULT_QUALIFICATION_SPAN = 200;
private boolean isSingleEvent;
private long doubleClickQualificationSpanInMillis;
private long timestampLastClick;
private Handler handler;
private Runnable runnable;

public DoubleClickListener() {
    doubleClickQualificationSpanInMillis = DEFAULT_QUALIFICATION_SPAN;
    timestampLastClick = 0;
    handler = new Handler();
    runnable = new Runnable() {
        @Override
        public void run() {
            if (isSingleEvent) {
                onSingleClick();
            }
        }
    };
}

@Override
public void onClick(View v) {
    if((SystemClock.elapsedRealtime() - timestampLastClick) < doubleClickQualificationSpanInMillis) {
        isSingleEvent = false;
        handler.removeCallbacks(runnable);
        onDoubleClick();
        return;
    }

    isSingleEvent = true;
    handler.postDelayed(runnable, DEFAULT_QUALIFICATION_SPAN);
    timestampLastClick = SystemClock.elapsedRealtime();
}

public abstract void onDoubleClick();
public abstract void onSingleClick();
}

Usage

 button.setOnClickListener(new DoubleClickListener() {
        @Override
        public void onDoubleClick() {
            Log.i("onClick", "double");
        }

        @Override
        public void onSingleClick() {
            Log.i("onClick", "single");
        }
    });
