getLocalVisibleRect ， 返回一个填充的Rect对象， 感觉是这个View的Rect大小，left，top取到的都是0

···

getGlobalVisibleRect ， 获取全局坐标系的一个视图区域， 返回一个填充的Rect对象；该Rect是基于总整个屏幕的

···

getLocationOnScreen ，计算该视图在全局坐标系中的x，y值，(注意这个值是要从屏幕顶端算起，也就是索包括了通知栏的高度)//获取在当前屏幕内的绝对坐标

···

getLocationInWindow ，计算该视图在它所在的widnow的坐标x，y值，//获取在整个窗口内的绝对坐标 (不是很理解= =、)

···

getLeft , getTop, getBottom, getRight,  这一组是获取相对在它父亲里的坐标

···

**注**：如果在Activity的OnCreate()事件输出那些参数，是全为0，要等UI控件都加载完了才能获取到这些(个人感觉好像是得有焦点，不是很清楚，待查查)
