Android: Listview onClick ne fonctionne pas correctement?

Question

J'ai Listview dont les données proviennent de website.data. Il s'affiche correctement dans une Listview, mais son onListItemClick ne se déclenche pas correctement.

public class OutKrys extends ListActivity { 
private ProgressDialog progress; 
ListView listView1; 
private ArrayList<Post> listItems = new ArrayList<Post>(); 
private PostAdapter post_Adapter; 
public static DefaultHttpClient httpclient = new DefaultHttpClient(); 
private class PostAdapter extends ArrayAdapter<Post> { 

    private ArrayList<Post> items = new ArrayList<Post>(); 

    public PostAdapter(Context context, int textViewResourceId, 
      ArrayList<Post> items) { 
     super(context, textViewResourceId, items); 
     this.items = items; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     try { 
      View v = convertView; 
      if (v == null) { 
       LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
       v = vi.inflate(R.layout.outkrys, null); 
      } 
      Post o = items.get(position); 
      if (o != null) { 
       TextView tt = (TextView) v.findViewById(R.id.Story); 
       TextView bt = (TextView) v.findViewById(R.id.userName); 
       TextView tm = (TextView) v.findViewById(R.id.Time); 
       ImageView iv=(ImageView)v.findViewById(R.id.OutKryImageView01); 
       if (tt != null) { 
        tt.setText(o.getStory()); 
       } 
       if (bt != null) { 
        bt.setText(o.getUserName()); 
       } 
       if (tm != null) { 
        tm.setText(o.getTime()); 
        if(iv!=null) 
        { 
          Drawable drawable = LoadImageFromWebOperations("abc.com/"+o.getImagePath()); 
          iv.setImageDrawable(drawable); 

        } 

       } 
      } 
      return v; 
     } catch (Exception e) { 
      progress.dismiss(); 
      return null; 
     } 
    } 
} 
private Drawable LoadImageFromWebOperations(String url) 

{ 
    try 
    { 

     InputStream is = (InputStream) new URL(url).getContent(); 
     Drawable d = Drawable.createFromStream(is, "src name"); 
     return d; 
    }catch (Exception e) { 
     System.out.println("Exc="+e); 
     return null; 
    } 
} 
@Override 
protected void onListItemClick(ListView l, View v, int position, long id) { 
    super.onListItemClick(l, v, position, id); 
    // Get the item that was clicked 
    Object o = this.getListAdapter().getItem(position); 
    String keyword = o.toString(); 
    Toast.makeText(this, "You selected: " + position, Toast.LENGTH_LONG) 
      .show(); 

}

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState);

    } catch (Exception e) {

      line = KryAbout.ReadInputStream(resContent).toString().trim(); 
     } else { 
     } 
     listItems.removeAll(listItems); 
     JSONArray ja = new JSONArray(line); 
     for (int i = 0; i < ja.length(); i++) { 
      p = new Post(); 
      JSONObject jo = (JSONObject) ja.get(i); 
      p.setStory(jo.getString("story")); 
      p.setFavorite(false); 
      p.setTime(jo.getString("time")); 
      p.setPid(Integer.parseInt(jo.getString("pid"))); 
      p.setUserName(jo.getString("username")); 
      p.setImagePath(jo.getString("profilepicture")); 
      listItems.add(p); 
     } 
    } catch (Exception e) {

    }

Je pense que vous devriez utiliser

@Override 
protected void onListItemClick(ListView l, View v, int position, long id) 
{ 
    ..... 
} 

au lieu de

@Override 
public void onItemClick(AdapterView<?> a, View v, int position, long id) 
{ 
    ..... 
}
