android listview数组适配器app force关闭

Question

您好我正在使用android。我通过自己的自定义创建了一个导航抽屉应用程序。我将自己的页面添加到每个菜单视图中，这是一个listview数组适配器。但是当单击菜单项时它看起来强制关闭。我使用了片段扩展。但它因某种原因被迫关闭，我找不到错误请帮助我，谢谢。 这是我的代码

  SentTaskFragment.java


public class SentTaskFragment extends Fragment {
     private ListView listView2;
     public SentTaskFragment(){}

     public View onCreateView(LayoutInflater inflater1, ViewGroup container,
                     Bundle savedInstanceState) {
     View rootView1 = inflater1.inflate(R.layout.fragment_photos, container, false);
     SentTask weather_data2[] = new SentTask[]
                    {
                      new SentTask(R.drawable.ic_launcher, "Task1","this is a task",R.drawable.green),
                        new SentTask(R.drawable.ic_launcher, "Task2","this is a task",R.drawable.red),
                        new SentTask(R.drawable.ic_launcher, "Task3","this is a task",R.drawable.red),
                        new SentTask(R.drawable.ic_launcher, "Task4","this is a task",R.drawable.green),
                        new SentTask(R.drawable.ic_launcher, "Task5","this is a task",R.drawable.red)
                    };
           SentTaskAdapter adapter = new SentTaskAdapter(getActivity(), 
                    R.layout.listview_item_row_sent, weather_data2);


               listView2 = (ListView)rootView1.findViewById(R.id.listView2);

              View header = (View)getActivity().getLayoutInflater().inflate(R.layout.listview_header_row_sent, null);
              listView2.addHeaderView(header);

              listView2.setAdapter(adapter);
              return rootView1;

    }
