Problems forcing a ScrollView to move to the top

I have a ScrollView that I want to move programatically to the top.

I do the following:

scrollll5.fullS开发者_开发问答croll(View.FOCUS_UP); scrollll5.postInvalidate();

and it works, but only if the ScrollView is NOT at the bottom already...

has anybody found a similar problem (and its solution)?

scrollTo(0,0) or smoothScrollTo(0,0) should work.
