notifyDataSetChanged example

Question

I\'m trying to use in my Android Application the notifyDataSetChanged() method for an ArrayAdapter but it doesn\'t work for me.

Answer 1

You can use the runOnUiThread() method as follows. If you're not using a ListActivity, just adapt the code to get a reference to your ArrayAdapter.

final ArrayAdapter adapter = ((ArrayAdapter)getListAdapter());
runOnUiThread(new Runnable() {
    public void run() {
        adapter.notifyDataSetChanged();
    }
});
