     public Object getItem(int position) { 
      return null; 
     } 

     @Override 
     public long getItemId(int position) { 
      return 0; 
     } 

     @Override 
     public View getView(int position, View convertView, ViewGroup parent) { 
      convertView=getActivity().getLayoutInflater().inflate(R.layout.fragment_my_auto_adap,parent,false); 
      return convertView; 
     }
