Android ListView setSelection() does not seem to work

Question

I have a ListActivity that implements onListItemClick() and calls a doSomething() function of the class. The latter contains l.s

Answer 1

For me it helped to set
ListView.setChoiceMode(ListView.CHOICE_MODE_SINGLE); or ListView.CHOICE_MODE_MULTIPLE
then
ListView.setSelection(position) or ListView.setItemChecked(position, true);
works fine
