[RESOLVIDO] Atualizar listView sem perder o foco

Praticamente nunca use listActivity, mas creio que tenha mesmo comportamento que uma listView, então pode ser que dê certo :)

private int index= 0;
private int top = 0;

@Override
protected void onPause(){
index = getListView().getFirstVisiblePosition();
View v = getListView().getChildAt(0);
top = (v == null) ? 0 : v.getTop();
}

@Override
protected void onResume(){
getListView().setSelectionFromTop(index, top);
}

So ListView.getFirstVisiblePosition() returns the top visible list item. But this item may be partially scrolled out of view, and if you want to restore the exact scroll position of the list you need to get this offset. So ListView.getChildAt(0) returns the View for the top list item, and then View.getTop() returns its relative offset from the top of the ListView. Then, to restore the ListView's scroll position, we call ListView.setSelectionFromTop() with the index of the item we want and an offset to position its top edge from the top of the ListView.
