Further to my problem, I have successfully used " myListView.setSelection(0); " to position the place in the array list correctly. That is part of my problem solved. The remaining part of the problem is that I have been unable to turn on the highlight at this position. When I press the down key on the dpad the highlight turns on at the position I have set as outlined above. But when I try to use " myListView.getSelectedItemPosition() " without manually highlighting the position first, the app crashes. That is why I want to highlight an item by program control, to prevent such a crash. Thanks for your help so far. Is there any way to turn on the selection highlight?
