Scrolling a TextView to a specific line

Question

I have a TextView inside a ScrollView. Let\'s say the ScrollView is named s and the TextView is named t.

I have many lines to be displayed

Answer 1

Found the answer here.

Instead of calling scrollTo directly, we must call post instead on the ScrollView. This works.

t.setText(aVeryLongString);
s.post(new Runnable() {
    @Override
    public void run() {
        int y = t.getLayout().getLineTop(40); // e.g. I want to scroll to line 40
        s.scrollTo(0, y);
    }
});
