RecyclerView通过GridLayoutManager实现多样式布局的示例

  GridLayoutManager layoutManage = new GridLayoutManager(getContext(), 2);
  recycerView.setLayoutManager(layoutManage);

   layoutManage.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() {
         @Override
         public int getSpanSize(int position) {
           return 0;
         }
       });

    /**
     * 如果单个item显示的字数大于指定某个值就显示一列 默认2列
     */

     //设置item数据大于多少字只显示一行 默认 超过九个字的程度只显示一列

     private static final int MAX = 9;

    private int setSpanSize(int position, List<TagBean> listEntities) {
      int count;
      if (listEntities.get(position).getTag_name().length() > MAX) {
        count = 2;
      } else {
        count = 1;
      }

      return count;
    }

    layoutManage.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() {
               @Override
               public int getSpanSize(int position) {
                 return setSpanSize(position,list);
               }
             });
