Android：ImageView.setImageResource在gridviewadapter中顯示不正確

我定義了一個gridview和gridviewadapter來選擇圖像。選擇2張或更多圖像時，一切正常。但是，當我選擇1時，位置= 1被positon = 0中的圖像覆蓋，並且這僅在第一次選擇1個圖像時發生。流動是getView（）在適配器：Android：ImageView.setImageResource在gridviewadapter中顯示不正確

@Override 
    public View getView(final int position, View convertView, final ViewGroup parent) { 
     L.d("mytest position ="+position+ "converView ="+convertView); 
     Holder holder; 
     if (convertView == null) { 
      holder = new Holder(); 
      convertView = mInflater.inflate(R.layout.grid_view_item, null); 
      holder.mSelectImage = (NGImageView) convertView.findViewById(R.id.iv_icon); 
      convertView.setTag(holder); 
     } else { 

      holder = (Holder) convertView.getTag(); 
     } 
     if (getData().size() > 0 && position != getData().size()) { 
      holder.mSelectImage.setVisibility(View.VISIBLE); 
      ImageItem imageItem = getData().get(position); 
      if (imageItem != null) { 
       if (imageItem.getImageUri().toString().startsWith("http")) { 
        loadNGImageView.LoadOptionsView(imageItem.getImageUri().toString(),holder.mSelectImage); 

       } else { 
        String imgUrl = BitmapUtil.IMAGE_URI_SUFFIX_SDCARD + imageItem.getImageUri().getPath(); 
        L.d("mytest LoadOptionsView"); 
        loadNGImageView.LoadOptionsView(imgUrl,holder.mSelectImage); 
       } 
      } 
     } else { 
      if (position == TopicPostFragment.DEFAULT_PHOTO_COUNT) { 
       holder.mSelectImage.setVisibility(View.GONE); 
      } else { 
       holder.mSelectImage.setVisibility(View.VISIBLE); 
       L.d("mytest setImageResource"); 
       holder.mSelectImage.setImageResource(R.drawable.guild_icon_img); 
      } 

     } 

     return convertView; 
    } 

error logs:

錯誤顯示： enter image description here

正確顯示： enter image description here

xml文件：

<?xml version="1.0" encoding="utf-8"?>

請顯示xml查看數據。 – Alexander

我替換了線holder.mSelectImage.setImageResource（R.drawable.guild_icon_img）;用代碼loadNGImageView.LoadOptionsView（「http://pic3.nipic.com/20090527/2488154_225452038_2.jpg」，holder.mSelectImage）;一切順利。這顯示setImageResource不能真正將圖像添加到imageview，爲什麼？ – judyzha

@Alexander我已經添加了xml查看數據〜 – judyzha

setImageResource不能與setImageURL在使用同時，有時setImageURL可能會覆蓋setImageResource和進行錯誤的顯示。如果你同時使用它們，你應該先setImageURL（null），然後使用setImageResource。
