ListFragment setOnItemClickListener не работает

Question

Работа с фрагментами и необходимость открытия нового действия при нажатии на ListActvity в Fragment. Но его отображение списка и кликабельное, но не открытие. Я пошел все методы, пожалуйста, взгляните на код.

Под нижеследующим строковым кодом он не открывает новую активность. listview.setOnItemClickListener (новый OnItemClickListener() не работает в намерения новой деятельности

public class FragmentOne extends ListFragment { 
    public boolean net; 
    ImageView ivIcon; 
    TextView tvItemName; 
    final static String LOG_TAG = "rnc"; 
    ListView listview; 

public FragmentOne() { 

} 

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

    View view = inflater.inflate(R.layout.twit_list, container, 
      false); 

    //View view = inflater.inflate(R.layout.twit_list, container,false); 
listview = (ListView) view.findViewById(android.R.id.list); 



    downloadTweets(); 


     listview.setOnItemClickListener(new OnItemClickListener() { 
      @Override 
      public void onItemClick(AdapterView<?> parent, View view, 
         int position, long id) { 
      // selected item 
      String lst_txt = parent.getItemAtPosition(position).toString().trim(); 

      System.out.println("Display text"+lst_txt); 
      // Launching new Activity on selecting single List Item 
      Intent i = new Intent(getActivity().getBaseContext(), SingleListItem.class);

Определи outsi de onCreate метод

@Override 
    public void onListItemClick(ListView l, View v, int position, long id) { 
     Log.i("FragmentList2", "Item clicked: " + id); 
    //  item = ((String)getListAdapter().getItem(position)); 

     Object selectedValue = this.getListAdapter().getItem(position); 
     product = selectedValue.toString(); 


     System.out.println("lota "+product); 

     Intent intent = new Intent(FragmentOne.this.getActivity(), SingleListItem.class); 
     intent.putExtra("product", product); 
    // Toast.makeText(getActivity(), item, Toast.LENGTH_LONG).show(); 
     startActivity(intent); 
    }
