ImageView를 어댑터에 넣으려고 할 때 null null

Question

어댑터에 이미지보기를 넣으려고합니다. 나는이 같은 ArrayAdapter와의 텍스트 뷰퍼팅의 예를 보았 기 때문에 나는이 작업을 수행하기 위해 노력하고있어

: 그래서 예에서 파생

adapter = new ArrayAdapter<String>(this.getActivity(), android.R.layout.simple_list_item_1, transmit_noktp_list) { 
     @Override 
     public View getView(int position, View convertView, ViewGroup parent) { 
      View view = super.getView(position, convertView, parent);   
      TextView text = (TextView) view.findViewById(android.R.id.text1);  
      return view; 
     } 
     }; 

은, 그때에도 이미지 뷰을 넣어 시도 그래서 시도

:

adapter = new ArrayAdapter<String>(this.getActivity(), android.R.layout.simple_list_item_1, transmit_noktp_list) { 
     @Override 
     public View getView(int position, View convertView, ViewGroup parent) { 
      View view = super.getView(position, convertView, parent); 
      ImageView img = (ImageView) view.findViewById(android.R.id.icon1); 
      TextView text = (TextView) view.findViewById(android.R.id.text1); 

      Resources resources = getResources(); 
      img.setImageDrawable(resources.getDrawable(R.drawable.inbox)); 

      return view; 
     } 
     }; 

아이콘 각 목록 항목에 & 텍스트를 달성

는 놀랍게도이 img.setImageDrawable(resources.getDrawable(R.drawable.inbox)); 선이 나에게 예외를 throwed (나는 '받은 편지함'아이콘이 res/drawable에 있음을 확신 할 수 있습니다, 내 IDE에서 보여도있어) :
