Use a Fragment to wrap your Listview. set setRetainInstance(true) so all Attributes are restored atomatically after restoring the instance. You don't need to use Bundles again. Then save the position of the first visible item and the offset to restore the exact position. (if you are not using Fragments you need to store top and index in the bundle)

private int top;
private int index; 

@Override onPause(){
  int index = mList.getFirstVisiblePosition();
  View v = mList.getChildAt(0);
  int top = (v == null) ? 0 : v.getTop();
  super.onPause();
}

@Override onResume(){
  super.onResume();
  mList.setSelectionFromTop(index, top);
}

have a look here

Thanks for the advise. Works great! – toom Dec 18 '15 at 13:04 — toom, Dec 18 '15 at 13:04

store the position and set it on back key pressed

@Override

public boolean onKeyDown (int keyCode, KeyEvent event) {

if (keyCode == KeyEvent.KEYCODE_BACK) {
    listview.setSelection(position);
    return true;
}

return super.onKeyDown(keyCode, event);
}

you can store last click position somewhere and on back press ....in onresume() ...do this..

For a direct scroll:

getListView().setSelection(21);

For a smooth scroll:

getListView().smoothScrollToPosition(21);

When traversed from a listview onPause() method of the source activity is called.You can maintain the state of the listview by adding following line to the end:

index = list.getFirstVisiblePosition();

in the on resume(onResume()) of your source activity , add this line at the end:

list.setSelectionFromTop(index, 0);

That should do the trick.

Use the ListView.setSelection(int position) method. It will select the list item at the specified position, but only if not in touch mode. If in touch mode, it will just scroll to the specified position so that the item at position is the first on the screen.

In onPause() method:

index = listView.getFirstVisiblePosition();

In onResume() method:

listView.setSelection(index);

Besides this, you must confirm that: setSelection(int position) method is invoked after setAdapter() of listView, or listView will be reset.
