Android: ImageView.setImageResource is not displaying correct in gridviewadapter

Question

I define a gridview and gridviewadapter to choose images. When select 2 or more images, all work well. But, when I select 1, the position =1 is covered by images in positon = 0, and this only happen the first time to choose 1 image. Flowing is getView() in adapter:

 @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;
    }

Answer 1

setImageResource cannot be used with setImageURL at the same time, sometimes setImageURL may cover setImageResource and make the wrong display. if you use them at the same time ,you should first setImageURL(null) ,then use setImageResource.
