Android Question how to implement a text log-type scrolling view

Hi Guys,
I need a quick tip. I would like to create a view that shows text lines as they get logged (something similar to the B4x editor log window). basically some text gets in and it is shown as last line and all the previous lines are auto scrolled up, then a new text gets in and again it is added as last line and auto scroll again.
thanks for your help!
