android中使用textView展示富文本中的图片异常

android中使用textView展示富文本信息，其中有图片信息，展示后发现图片img标签中的宽高样式失效，请问需要怎么处理？代码如下：

         @Override
        public View getView(int position, View convertView, ViewGroup parent) {
          ViewHolder holder = new ViewHolder(mContext, parent, R.layout.item_list_ai_error_question_collect_add_eq, position);
          holder.setText(R.id.itemNo, "错题" + (position + 1));
          //holder.setText(R.id.questionStem, Html.fromHtml(mDatas.get(position).getQuestionStem()));
          TextView questionStem = (TextView) holder.getView(R.id.questionStem);
          imgGetter = new AiErrorQuestionCollectAddEqAdapter.NetworkImageGetter(context);
          questionStem.setText(Html.fromHtml(mDatas.get(position).getQuestionStemMathML(),Html.FROM_HTML_MODE_COMPACT,imgGetter,null));
          //添加或删除按钮
          View addOrDelete = holder.getView(R.id.addOrDelete);
          addOrDelete.setOnClickListener(new myOnClickListener(holder,mDatas.get(position),"0001"));
          return holder.getConvertView();
      }
