推荐答案

有基本上在渲染过程中3个步骤。首先，你的观点得到测量，这是刚刚的宽度和高度。然后，控制是通过布局，这基本上只是告诉他们所在的测量里面的所有意见。最后，一​​切都绘制。这是其中的控制实际上是在画布上绘制。因此，这些可能是你在看什么

There are basically 3 steps during the render process. First, your view gets measured, this is the just the width and height. Then the controls are go through layout, this basically just tells all the views where they are located inside the measurements. And finally, everything is drawn. This is where the controls are actually drawn on the canvas. So those are probably the what you are looking at.
