Hello guys,
I want to use scrollview in my app. I tried to add a text view into
the scrollview, but I can't see anything rendered, except the
background color of the scroll view.
here is how I did it:
public class MyView extends ViewGroup

ScrollView myScrollview;
Textview tv;
Hello,
I want to write some transparent view, but there is no setAlpha
defined with View, although the document claims that there is. I am
wondering if setAlpha is deprecated? And how am I suppose to set
alpha?
Thank you very much,

that other
folks with Xooms are having that same problem.
