New to IntelliJ, check kb but unable to find answer. Using 12.1.3
I have tried to use the designer for assistance with an Android layout. While the end result seems ok, I have question about what this designer is showing and why. Specifically, I have a tablelayout, the first tablerow of which has three cells. I've set the layout:width to 0dp and have used layout:weight to apportion the column sizes. However, in the design window there are two unexplained (or at least confusing to me) boxes drawn when selecting the first cell of the table row. One is red, the other is blue. Both are much narrower than that cell and in the case of the blue box, the height of the entire layout.
However, when selecting the second or third cell, the red box appears to be the correct (or at least expected) dimension around that layout element. The same can be said of other portions of the layout (not visible in attachment) except again, first cell in a table row.is wrong size.
I've included image. What is going on? Is it a problem with my layout or the designer? I've run on a physical device and the layout seems to work ok.
Thanks for your help.
