auto-scrolling TextView in android to bring text into view

Question

I have a TextView that I\'m dynamically adding text to.

in my main.xml file I have the properties set to make my max lines 19 and scrollbar

Answer 1

to avoid creating dummy scroolview I did

int top_scr,rec_text_scrollY;
top_scr=(int)rec_text.getTextSize()+rec_text.getHeight();
rec_text_scrollY=rec_text.getLineBounds(rec_text.getLineCount()-1, null)-top_scr;
    //repeat scroll here and in rec_text.post. 
    //If not scroll here text will be "jump up" after new append, and immediately scroll down
    //If not scroll in post, than scroll will not be actually processed
if(rec_text_scrollY>0)rec_text.scrollTo(0, rec_text_scrollY);
rec_text.post(new Runnable(){
    @Override
    public void run() {
        if(rec_text_scrollY>0)rec_text.scrollTo(0, rec_text_scrollY);
    }                   
});
