Use a Handler object to show popup.

Handler hand = new Handler()
{
    @Override
    public void handleMessage(Message msg)
    {
        show_popup();

    }
};

and call handler in onCreate()

protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.question_layout);
    hand.sendEmptyMessage(0);
}
