嗯，这很简单，只需覆盖即可。

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();
}

用法

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

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