Comment(by erikos):

 Thanks for the new patch Carlos. I did test with my modified HelloWorld
 activity, which has a scrolled window, textview inside. When I tap on text
 at the bottom the text to edit is moved up, right above the OSK. The
 cursor does as well update the position accordingly (it is over the OSK
 though).

 If I hit enter, the current text gets under the OSK. Another issue is that
 if I scroll in that situation everything gets messed up in regards to the
 position. A regression for the scrolled window, is that when overshooting
 the widget does not take up the space again. A border is left.

 The terminal and Browse use case both do not work with your patch. Is that
 expected. Anything we have to change here? Which use case do you test
 with?
