如果條件在自定義適配器中不起作用（getView（））

Question

我正在嘗試使用equalignorecase（）比較兩個字符串，但是它不起作用，如果我將圖像資源設置為imageView而不使用if條件，則它可以工作。我也使用過string ==“” ..但仍然存在相同的錯誤

Java代碼：

 public View getView(int position, View convertView, ViewGroup parent) {
          ViewHolder holder;
          if(convertView==null)
          {
               convertView = mInflater.inflate(R.layout.androidnewxml,parent,false);
               holder = new ViewHolder();
               holder.name = (TextView)convertView.findViewById(R.id.textView_adapter);
               holder.status= (ImageView)convertView.findViewById(R.id.showStatus);  
               holder.description= (TextView)convertView.findViewById(R.id.ShowDescription);  


               convertView.setTag(holder); 
          }else{
                holder = (ViewHolder)convertView.getTag();
          } 
                //String checkStatus="Yes";
                holder.name.setText(list1.get(position).getKITTYDATE());
                String  checkStatus= list1.get(position).getPARTICULAR();
              Log.d("status", checkStatus);
               if(checkStatus.equalsIgnoreCase("Yes"))
               {
                   holder.status.setImageResource(R.drawable.acceptbuttons);
               }

               else if(checkStatus.equalsIgnoreCase("No"))
               {
                    holder.status.setImageResource(R.drawable.declinebuttons);
               }
               else
               {

               }

                holder.description.setText(list1.get(position).getINSTALLMENT());


                Log.d("hhhhhhhhhhh","jjjjjjjj"+convertView);

          return convertView;

    }
