查找视图的宽度 - onSizeChanged 在我需要它之后调用
基本上我正在构建一个自定义滚动条，其中有一个表格布局。我将表行动态插入到表布局中，然后将文本视图插入到这些行中。我需要知道整个滚动视图的宽度，以便我可以获取该长度并除以每个文本视图的长度。我正在使用 onSizeChanged 方法来获取滚动视图宽度，效果很好。
然而，问题是，我在构造滚动条后立即调用“添加行”方法。这个“添加行”方法显然是在滚动条有机会进入 onSizeChanged 方法之前被调用的，因此在宽度变量仍设置为零时发生“添加行”调用。
有什么办法可以阻止这种交错吗？或者是否有更有效的方法来在构造函数中查找滚动视图的宽度？谢谢！
basically I'm building a custom scroll bar that has a table layout inside it. I'm dynamically inserting table rows into the table layout and then text views into those rows. I need to know how wide the overall scrollview is so I can take that length and divide by each textview's length. i'm using the onSizeChanged method to get the scroll views width, which works fine.
However, the problem is, I call my "add a row" method right after constructing the scroll bar. this "add a row" method is apparently being called before the scroll bar has a chance to enter into the onSizeChanged method, and as such the call to "add a row" happens while the width variable is still set to zero.
Is there a way I can stop this interleaving? Or is there a more efficient way to find the width of the scroll view in the constructor? Thanks!

您不能使用
handler及其postDelayed方法推迟对addRow的调用吗？Couldn't you postpone the call of
