android - 如何测量高达毫秒之间的点击时间？

Question

我想以毫秒为单位测量连续点击之间的时间。我怎样才能做到这一点？

Answer 1

View myView;
long previousClickTime;

...

myView.setOnTouchListener(new View.OnTouchListener(){
    @Override
    public boolean onTouch(View v, MotionEvent ev)
    {
        long temp = System.currentTimeMillis();
        if (previousClickTime != 0)
        {
            Log.i("MyView", "Time Between Clicks=" + (temp - previousClickTime));
        }
        else
        {
            Log.i("MyView", "First Click");
        }
        previousClickTime = temp;

        return true;//Note that you can return false, and any underlying Views will then receive this touch event.
    }
}

附带说明，如果您尝试检测双击，请尝试GuestureDetector.setOnDoubleTapListener。

覆盖onCLick()事件。

活动内部onClick()。让您的应用获得第一次点击并存储时间。然后存储第二次，得到两次抽头的差值。并且只是显示差异。

下面的代码非常简单，可能不是您要找的，但我把它放在那里作为一个非常微不足道的例子。

long initialTime = 0;
long endTime = 0;

onClick() {

    if(initialTime == 0){
        initialTime = System.currentTimeMillis();
    } else {
        endTime = System.currentTimeMillis();
        long diff = endTime - initialTime;
        initialTime = endTime;
        Log.i("your app", "time between click: " + diff);
    }

}
