Question

I have a ListView inside an AppWidget. Each row of the ListView has a custom layout, AppWidget specifies a minHeight, as required. The problem is that ListView exceeds the dimensions of the AppWidget, and some rows simply hang below the widget boundaries.

I have tried everything I could think of, fixing the height of ListView, using match_parent and/or wrap_content or rows and ListView, but I have not been able to fix this.

Has someone else faced this problem? How do I make the ListView fit inside the widget boundaries and scroll, instead of rows getting outside the boundary?

Answer 1

Well I have root-caused the issue, and I am to blame here, at least partly.

I am asked to use a custom background for the ListView, and the 9-patch I received had a shadow drawn below the ‘content’ background. Android used the whole png for drawing the background, lending an appearance of ‘one row hanging off the content’ appearance to the widget.

I verified this by using a solid color as background – it extends properly to cover entire ListView.

My learning:
1. The minWidth and minHeight attributes for the widget are exactly what they say; Android WILL give more space to the widget if it can. 🙂
2. You’ve specified “minimum” width, and your actual width is being determined by the width of a child View. Given that such a case could be common, setting the top-level layout width and height to wrap_content in the widget’s main view seems a reasonable thing to do.
