Scroll to a specific view in scroll view

Question

I have added a scrollview and the subchilds inside the scrollview. At some point i need to scroll to a specific view.

Answer 1

I think I have found more elegant and error prone solution using

ScrollView.requestChildRectangleOnScreen

No math involved, and contrary to other proposed solutions, it will handle correctly scrolling both ways up and down.

void scrollToRow(ScrollView scrollView, LinearLayout linearLayout, TextView textViewToShow) {
    Rect textRect = new Rect(); //coordinates to scroll to
    textViewToShow.getHitRect(textRect); //fills textRect with coordinates of TextView relative to its parent (LinearLayout) 
    scrollView.requestChildRectangleOnScreen(linearLayout, textRect, false); //ScrollView will make sure, the given textRect is visible
}

It is a good idea to wrap it into postDelayed to make it more reliable, in case the ScrollView is being changed at the moment

private void scrollToRow(final ScrollView scrollView, final LinearLayout linearLayout, final TextView textViewToShow) {
    long delay = 100; //delay to let finish with possible modifications to ScrollView
    scrollView.postDelayed(new Runnable() {
        public void run() {
            Rect textRect = new Rect(); //coordinates to scroll to
            textViewToShow.getHitRect(textRect); //fills textRect with coordinates of TextView relative to its parent (LinearLayout) 
            scrollView.requestChildRectangleOnScreen(linearLayout, textRect, false); //ScrollView will make sure, the given textRect is visible
        }
    }, delay);
}

Just nice isn`t?
