[android-developers] Re: Extremely frustrating = TextView in ScrollView - Scroll to bottom?
Oh dear...
I should have tried that first. It works beautifully!
Thanks very much skink. I wasn't able to get the Selection.SetSelection
to work even if I posted it later. There's obviously something I don't
quite understand about how all of this works. - Like why I need to put a
TextView that supports scrolling inside a scrollview to do this
anyway... :S
After experimenting a bit more I was only able to get the following 2
commands to work:
sv.post(new Runnable() {
public void run() {
sv.scrollTo(0, tv.getHeight());
}
});
And
sv.post(new Runnable() {
public void run() {
sv.fullScroll(ScrollView.FOCUS_DOWN);
}
});
Thanks skink Raphael

[android-developers] Re: Extremely frustrating = TextView in ScrollView - Scroll to bottom?
I often use a TextView withing a ScrollView as a quick log in early prototype of apps, for debugging. Typically I just set the selection to the end of the text, which moves the caret and thus makes sure it's visible: mLogTextView.append(msg); mLogTextView.setSelected(true); Spannable text = (Spannable) mLogTextView.getText(); Selection.setSelection(text, text.length()); R/ On Wed, May 27, 2009 at 7:28 PM, Peter Carpenter peter.carpen...@skytechnologies.com wrote: Hi guys, I can’t for the life of me work out how to get a text view to be displayed scrolled to the bottom. It appears that plenty of people have asked about this in newsgroups, but no solution offered. textView.setText(s); scrollView.fullScroll(ScrollView.FOCUS_UP); The above code is called, and whilst the text is updated correctly, the view is not scrolled. (I’ve tried ScrollView.FOCUS_DOWN) and that doesn’t work either Do I need to force the scrollView to measure itself before calling the scroll function? If so what would be the best way to go about doing this and then calling the scroll. I’ve also tried setting the text as spannable and setting the cursor position to the end.
