Android下模拟点击事件

要实现在WebView上模拟点击效果，效果一直不好，函数是搜索得到的，有几点需要注意：

1、按下和松开之间的时间要相同

2、用dispatchTouchEvent分发事件

3、调用recycle()回收事件

    private void setSimulateClick(View view, float x, float y) {        long downTime = SystemClock.uptimeMillis();        final MotionEvent downEvent = MotionEvent.obtain(downTime, downTime,            MotionEvent.ACTION_DOWN, x, y, 0);        //downTime += 2500;        final MotionEvent upEvent = MotionEvent.obtain(downTime, downTime,            MotionEvent.ACTION_UP, x, y, 0);//        view.onTouchEvent(downEvent);//        view.onTouchEvent(upEvent);        view.dispatchTouchEvent(downEvent);        view.dispatchTouchEvent(upEvent);        downEvent.recycle();        upEvent.recycle();    }
