[android-developers] Re: Scrolling text (marquee) in an AppWidget

Just thought I would post my solution, if anyone else wants to know.

I had to add android:focusableInTouchMode="true" in order to get it to
work. I also might have added android:duplicateParentState="true" to
get it to work, but I'm not sure if that's necessary.

Now that I got it working, though, I would not recommend trying this.
It will not work reliably, as your widget will have to be focused in
order for it to scroll. As soon as the user clicks somewhere to make
it lose focus, or uses the trackball, the text no longer scrolls. We
decided on a different approach, and I would recommend anyone else
thinking that they have to have scrolling text in a widget to do the
same.
