如何测量抽头之间的时间可达毫秒？

问题描述

我要测量连续抽头以毫秒为单位的时间。我怎样才能做到这一点？

解决方案

 查看MyView的;
长previousClickTime;

...

myView.setOnTouchListener（新View.OnTouchListener（）{
    @覆盖
    公共布尔onTouch（视图V，MotionEvent EV）
    {
        长临时= System.currentTimeMillis的（）;
        如果（previousClickTime！= 0）
        {
            Log.i（MyView的+（TEMP之间点击=时间 -  previousClickTime））;
        }
        其他
        {
            Log.i（MyView的，首次点击）;
        }
        previousClickTime =温度;

        返回true; //注意，您可以返回false，以及任何潜在的意见，然后将接收该触摸事件。
    }
}
 

作为一个侧面说明，如果你想检测双击，尝试 GuestureDetector.setOnDoubleTapListener 。

I want to measure time between consecutive taps in milliseconds. How can I do this?

解决方案

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.
    }
}

As a side note, if you are trying to detect a double click, try GuestureDetector.setOnDoubleTapListener.
