Thanks, thats a nice solution. Useful diagram too. However, I probably should have explained more about what I'm trying to do, because if I understand you correctly, that solution does not help what I want to do.
In my horizontal LinearLayout, there are actually two TextViews which sit side by side one another (no gap). In the normal (i.e. not too long text) situation the two TextViews are wide enough to fit all the text on one line. However, when the text is too long then the text needs to wrap and so I want to set the maxWidth of the first TextView (or the minWidth of the second TextView). Here is a two-item ListView I have. Each item is a LinearLayout containing the two TextViews: +------------------------------------------------------+ This is short | This is also short +------------------------------------------------------+ This is not at all short | This is not so so I need to wrap | short either +------------------------------------------------------+ If I don't use maxWidth then the second TextView is sometimes too narrow.
