어댑터 목록보기 항목 클릭 이벤트

Question

는 할이 됐나요?

@Override 
protected void onPostExecute(final ChannelPair p) { 
    HiddenChannelsListAdapter adapter = new HiddenChannelsListAdapter(p.ctx, p.channelList); 
    p.lv.setAdapter(adapter); 
    p.lv.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() { 

     @Override 
     public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) { 
      Log.i("CLICKED ON LV ITEM", "YEA"); 

     } 

     @Override 
     public void onNothingSelected(AdapterView<?> arg0) { 
      // TODO Auto-generated method stub 

     } 
    }); 
} 

실제로 이벤트가 발생하지 않는다고 생각합니다. 적어도 항목이 선택되지 않았습니까?

UPDATE는 그래서 모두 같은 파일에 이제 그는 AsyncTask를에서 물건을 제거하고 새로운 스레드에 추가. 하지만 여전히, 나는 클릭이 연결되어이 제품은 항목

에서 클릭을 얻을 수 없습니다

((Activity)ctx).runOnUiThread(new Runnable() { 
          public void run() { 
           HiddenChannelsListAdapter adapter = new HiddenChannelsListAdapter(ctx, channelList); 
            ListView lv = (ListView) vw.findViewById(R.id.list); 
            lv.setAdapter(adapter); 
            lv.setOnItemClickListener(new android.widget.AdapterView.OnItemClickListener() 
            { 
             @Override 
             public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) 
             { 
              Log.i("CLICKED ON LV ITEM", "YEA"); 
             } 
            }); 
          } 
         });
