类名称：ViewTarget
方法名：getSize

ViewTarget.getSize介绍

[英]Determines the size of the view by first checking android.view.View#getWidth() and android.view.View#getHeight(). If one or both are zero, it then checks the view's LayoutParams. If one or both of the params width and height are less than or equal to zero, it then adds an android.view.ViewTreeObserver.OnPreDrawListener which waits until the view has been measured before calling the callback with the view's drawn width and height.
[中]通过首先检查android来确定视图的大小。看法查看#getWidth（）和android。看法查看#getHeight（）。如果其中一个或两个都为零，则会检查视图的LayoutParams。如果一个或两个参数的宽度和高度都小于或等于零，则会添加一个android。看法ViewTreeObserver。OnPreDrawListener，它在使用视图绘制的宽度和高度调用回调之前等待视图被测量。
