Set Scroll position of a listview

Requirement :

Doesn't change the scroll position even if some list items are added to Listview dynamically.

problem faced : Scroll moving to first after listitems are added.

Solution:

// save index and top position
int index = mList.getFirstVisiblePosition();
View v = mList.getChildAt(0);
int top = (v == null) ? 0 : v.getTop();

// ...

// restore
mList.setSelectionFromTop(index, top);
