android导航抽屉app强制关闭

Question

您好我正在使用android我创建了一个导航抽屉应用程序。我编辑了其中一个视图，并且我还将Extends片段更改为片段活动。现在问题出在抽屉菜单中。我编辑的页面没有显示，点击它强行关闭。我是android新手，所以请帮我找错。感谢

这是我的代码

      public class PagesFragment extends FragmentActivity {

       private ListView listView1;
       public PagesFragment(){}

       public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

          View rootView = inflater.inflate(R.layout.fragment_pages, container, false);
         Weather weather_data[] = new Weather[]
               {
                    new Weather(R.drawable.ic_launcher, "Task1","this is a task",R.drawable.green),
                    new Weather(R.drawable.ic_launcher, "Task2","this is a task",R.drawable.red),
                    new Weather(R.drawable.ic_launcher, "Task3","this is a task",R.drawable.red),
                    new Weather(R.drawable.ic_launcher, "Task4","this is a task",R.drawable.green),
                    new Weather(R.drawable.ic_launcher, "Task5","this is a task",R.drawable.red)
            };
             WeatherAdapter adapter = new WeatherAdapter(this, 
                 R.layout.listview_item_row, weather_data);


           listView1 = (ListView)findViewById(R.id.listView1);

           View header = (View)getLayoutInflater().inflate(R.layout.listview_header_row, null);
           listView1.addHeaderView(header);

           listView1.setAdapter(adapter);
           return rootView;


       }
      }
