The problem is about width and height of the view. As I understood, the view uses some value that is equal to zero while launching to draw the circle. But it really needed to use the other value (that calculates later).
问题是关于视图的宽度和高度。据我所知,视图在启动绘制圆时使用了一些等于零的值。但它确实需要使用其他值(稍后计算)。
This is reather popular problem: onCreate .. onPause methods do not know its own sizes and window sizes.
这是reather流行的问题:onCreate .. onPause方法不知道自己的大小和窗口大小。
Solution: is to create your own observer that execute some code after the activity will know its sizes.
解决方案:创建自己的观察者,在活动知道其大小后执行一些代码。
