嘗試在FragmentTabHost中實現ListView時的ClassCastException

Question

我在我的應用程序中使用了ActionBarSherlock，它適用於2.3.3及更高版本。在我的應用程序片段選項卡主機中，我試圖在其中一項活動中實施ListView，但我得到ClassCastException。請找到必要的代碼。

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


      // Create FragmentTabHost 
      mTabHost = new FragmentTabHost(getSherlockActivity()); 
      // Locate fragment1.xml to create FragmentTabHostx 
      mTabHost.setup(getSherlockActivity(), getChildFragmentManager(), R.layout.fragment1); 
      // Create Tab 1 

      mTabHost.addTab(
        mTabHost.newTabSpec("tab1").setIndicator("ALL", 
          getResources().getDrawable(R.drawable.all)), 
        CreateEvent.class, null); 
      //mTabHost.addTab(mTabHost.newTabSpec("tab1").setContent(R.drawable.fb).setIndicator("Tab 1"), CreateEvent.class, null); 
       // Create Tab 2 
      mTabHost.addTab(mTabHost.newTabSpec("tab2").setIndicator("NEARBY",getResources().getDrawable(R.drawable.near_by)), CreateEvent.class, null); 

      mTabHost.getTabWidget().setBackgroundColor(Color.GRAY); 
      return mTabHost; 
     } 

CreateEvent.class有一個listView在裏面。 public class CreateEvent extends SherlockListActivity implements OnItemClickListener{ }

logcat的
