Aug 17, 2011 11:34PM

I get a 'java.lang.ArithmeticException: divide by zero' exception when programmatically building a table layout with setStretchAllColumns(true). If I comment out the line with setStretchAllColumns(true), I don't get the exception, but nothing renders on the screen. Also, I'm new to android development, so please let me know if it's just something I'm doing wrong.

Here's the stack trace:
