            public void onItemClick(AdapterView<?> arg0, View arg1, int postion,long arg3) {
            Intent intent = null;
            switch (postion)
    {
        case 0:intent = new Intent(arg0.getContext(), Activity01.class);break;
        case 1:intent = new Intent(arg0.getContext(), Activity01.class);break;
 
    }
        startActivity(it);
            }
