Android: TextView in ScrollView continous scrolling

Sometimes when continuously outputting text to TextView, you would like it to scroll down:



textView.addTextChangedListener(new TextWatcher() {
@Override public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}

@Override public void onTextChanged(CharSequence s, int start, int before, int count) {
// scroll down whenever log text updated to display latest info on the screen  
        
        scrollView.post(new Runnable() {
@Override public void run() {
scrollView.fullScroll(ScrollView.FOCUS_DOWN);
}
});
}

@Override public void afterTextChanged(Editable s) {
}
});
