Scrollable TextView in Android Widget

Question
I would like to create an android widget with a scrollable textview.
The solutions given to this question Making TextView scrollable on Android cannot be applied because it is a widget:
1. This
findViewById(R.id.textview).setMovementMethod(new MovementMethod());
does not work, since findViewById
is not available in AppWidgetProvider
but only in Activity
.
2.Putting a ScrollView
around the TextView
also does not work, because I get an
InflateException
:
android.view.InflateException: Binary XML file line #23: Error inflating class ScrollView
Can anybody give me a hint, how to make a TextView
in a Widget scrollable?
Solution 2
It looks like this is not possible.
More on this can be found here: http://code.google.com/p/android/issues/detail?id=9580
and here: How to make a scrollable app widget?
So, probably it is possible to do make appwidgets scrollable in the HTC sense environment but not for normal android environments.
A way around this is to add buttons that go up and down in a list.
OTHER TIPS
I solved this problem by putting the text view inside ListView with single node, which is supported in App widget.

I have been working on this with two buttons which increment and decrement through an array. Just having trouble accessing the global variables. Did you make any headway on this?
In mainactivity.java:
after code text view:
TextView txt = (TextView) findViewById(R.id.textView id);
Enter this code:
txt.setMovementMethod(new ScrollingMovementMethod());
and you will be ok.
