Try this, call adapter.notifyDataSetChanged() inside runOnUiThread.

YourActivity.this.runOnUiThread(new Runnable() {
 @Override
 public void run() {
 adapter.notifyDataSetChanged();
}
});

You have to call .invalidate(); on the ListView to tell the framework the the view is outdated and should be redrawen!

UI is update outside the main thread. Put all the logic inside an asynctask and in postexecute, call the adapter.notifyDataSetChanged();
