解决android 单击事件和移动事件的冲突

最近点项目中，做到一个悬浮框，类似360的，但是碰到一个问题。单击和移动出现了冲突，两个点击事件出现了重合，即，移动的时候也会响应单击的事件，研究了一会后，可以通过取得按下的时间和手指地抬起时间计算

view.setOnTouchListener(new OnTouchListener() {
long downTime;
public boolean onTouch(View v, MotionEvent event) {
x = event.getRawX();
y = event.getRawY() - 25;
Log.i("currP", "currX" + x + "====currY" + y);
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
state = MotionEvent.ACTION_DOWN;
downTime=System.currentTimeMillis();
StartX = x;
StartY = y;
mTouchStartX = event.getX();
mTouchStartY = event.getY();
Log.i("startP", "startX" + mTouchStartX + "====startY"
+ mTouchStartY);

break;
case MotionEvent.ACTION_MOVE:
state = MotionEvent.ACTION_MOVE;
updateViewPosition();
break;

case MotionEvent.ACTION_UP:
state = MotionEvent.ACTION_UP;
if(System.currentTimeMillis()-downTime<100){
Toast.makeText(getApplicationContext(),"打开",Toast.LENGTH_SHORT).show();
}
updateViewPosition();

mTouchStartX = mTouchStartY = 0;
break;

}
return false;
}
});
