finding a view's width - onSizeChanged called AFTER I need it

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 t开发者_运维技巧he scroll view in the constructor? Thanks!

Couldn't you postpone the call of addRow using a handler and its postDelayed method?
