public final boolean getGlobalVisibleRect(Rect r) public boolean getGlobalVisibleRect(Rect r, Point globalOffset) public final boolean getLocalVisibleRect(Rect r) public void getLocationInWindow(int[] location) public void getLocationOnScreen(int[] location) public void getWindowVisibleDisplayFrame(Rect outRect) getLeft()、getTop()、getRight()、getBottom() getX()、getY() getTranslationX()、getTranslationY() getScrollX()、getScrollY()首先明白Android 全局坐标系和相对坐标系
全局坐标系是整个手机屏幕，相对坐标系是某个View自己的小坐标系
先看结论：
getGlobalVisibleRect(Rect r)
Global表示全局，Visible表示可见，意思就是，计算一个View在全局 坐标系里的可见区域的矩形位置
getGlobalVisibleRect(Rect r, Point globalOffset)
和getGlobalVisibleRect(Rect r)是一样的但是有一个Point 参数，记录的是View的左上顶点在全局坐标系的里点位置
getLocalVisibleRect(Rect r)
以View自己为坐标系计算自己的可见矩形区域坐标
getLocationInWindow(int[] location)和getLocationOnScreen(int[] location)
这两个及其相似，Android里的顶层View是PhoneWindow,里面有个DecorView，InWindow的含义就是以这个PhoneWindow为坐标系，location的数组长度为2，表示View的左上顶点的x、y坐标。OnScreen表示整个屏幕（全局坐标）当我们在Activity中使用时，它们两个的值是一样的，但是当我们在Dialog里使用时，就不一样了，Dialog有自己的DecorView与Activity的DecorView不是一个对象。
getWindowVisibleDisplayFrame(Rect outRect)
得到窗口的可视区域，不包含状态栏。就是内容区+标题栏
getLeft()、getTop()、getRight()、getBottom()
以当前view的父View为坐标系，getLeft()、getTop()左上顶点的坐标，getRight()、getBottom()右下顶点的坐标。
getX()、getY()
相对父容器，左上角的坐标，如果父容器发生滚动ScrollX、ScrollY，对getX( )与getY( )没有影响。
如果view没有移动，getX()、getY()可能会与getLeft()、getTop()相同。
但是但我们直接调用setX( )、setY( )时，getLeft()、getTop()系列的值并没有改变。
getTranslationX()、getTranslationY()
在父容器里的位移，负值是向左或向上。正值向右或向下
getScrollX()、getScrollY()
发生滚动表示view里的内容发生滚动，正值表示内容向左或向上滚动
，负值表示内容向右或向下滚动。滚动的值没有影响子view的坐标位置
实例
Dialog的布局和上面的一样，只是没有按钮
