프로그램이 onclick 수신 대기하지 않는 것 같습니다.

Question

안녕하세요 아래 코드는 일부 코드입니다.하지만 디버깅 할 때 결코 onitemclicklisten 루틴에 도달 할 수 없습니까? 당신이

listContent.setOnItemClickListener(new OnItemClickListener() { 

에 중단 점을 설정하면 클릭하면

       int position, long id) {  

      String neil = "test"; 

      neil = neil + "test"; 

     } 
     }); 


    } 




} 

Answer 1

클릭 수신기를 확인하는 가장 쉬운 방법은 일부 logcat 인쇄를 추가하는 것입니다 (예 :

listContent.setOnItemClickListener(new OnItemClickListener() { 
    public void onItemClick(AdapterView<?> parent, View view, 
      int position, long id) {  

     Log.d(TAG, "Click!"); 
    } 
    }); 

Answer 2

이 중단되지 않을 수도 있습니다.

는

String neil = "test"; 

및 디버깅에 중단 점을 설정하십시오.
