Research direction

Start with the AndroidNote section titled “安卓自定义View进阶-分类与流程” and review its guidance on onMeasure, super.onMeasure, and setMeasuredDimension. Compare the two behaviors in Android custom View measurement, then update the section with a clear explanation answering why the latter is used when dimensions are changed; no file or test is named.

如果对View的宽高进行修改了，不要调用 super.onMeasure( widthMeasureSpec, heightMeasureSpec); 要调用 setMeasuredDimension( widthsize, heightsize); 这个函数。

这是为什么？
