listView.setSelection(position); send selected row to top of the ListView. listView.setSelectionFromTop(position, 20); this method also send selected row top of the ListView. But second argument (in this method 20) distance of the ListView`s top edge. (include padding) If you neccessary to finish the first Activity you need to save the position of item and when back button clicked send saved position to your Activity. (Bundle, static class etc...)

IDEA

Simply you need to do is to create second activity without calling finish(). When user clicks on the back button in second activity just call onBackPressed(); to resume first activity.

So do not use finish() method in first activity and use onBackPressed() in secound activity.

What you should do:

In first activity:

 @Override
            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {
           //your logic gose here
           // start new activity without finishing current activity
}

In new activity:

just call onBackPressed(); in second activity.It will finish the second activity and automatically resume the first activity.

BackButton.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
           //call onBackPressed(); to resume privious activity.
            onBackPressed();

        }
    });
