onItemClickListener（）的ListFragment startActivity崩溃应用程序

Question

我有从ListFragment onItemClickListener（）调用startActivity（intent）的问题。当我从列表视图中点击一个项目时，应用程序崩溃。

代码是在这里：

public class AndroidFragment extends SherlockListFragment{ 

    static{ 
     StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); 
     StrictMode.setThreadPolicy(policy); 
    } 
    static final String URL = "***"; 
    // XML node keys 
    static final String KEY_ITEM = "novost"; // parent node 
    //static final String KEY_ID = "id"; 
    static final String KEY_NAME = "naslov"; 
    static final String KEY_COST = "datum"; 
    static final String KEY_DESC = "text"; 
    static final String KEY_LINK = "link"; 
    static final String KEY_LINK1 = "doc"; 
    ArrayList<HashMap<String, String>> menuItems; 
    String[] from = { KEY_NAME, KEY_DESC, KEY_COST,KEY_LINK,KEY_LINK1}; 

    /** Ids of views in listview_layout */ 
    int[] to = { R.id.naslov, R.id.novost, R.id.datum,R.id.link,R.id.link1}; 
    ListView list; 

    @Override 
    public void onActivityCreated(Bundle savedInstanceState) { 
     super.onActivityCreated(savedInstanceState); 
     new loadListView().execute(); 
     ListView lv = getListView(); 

     lv.setOnItemClickListener(new OnItemClickListener() { 

      @Override 
      public void onItemClick(AdapterView<?> parent, View view, 
        int position, long id) {

       String link1 = ((TextView) view.findViewById(R.id.link1)).getText().toString();

       } 
       //in.putExtra("link1", link_asd); 
       startActivity(in); 

      } 
     }); 


    }
