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

// ...

// restore index and position
listview.setSelectionFromTop(index, top);

Public void reset(Arralist<string> itemsList) { 

this.adapterList.clear();
this.adapterList = itemList;

notifydatasetchanged();

}

Create this method in adapter class

and call like this after setadapter().

yourAdapterRef.reset(itemList);

Try this way it will work.
