其实就是适配器的写法~ （附：copy loader的~剪刀手~）

初始化部分：

//TODOmAdapter = new DemoDifferentRecycleViewAdapter(this);LinearLayoutManager mLinearLayoutManager1 = new LinearLayoutManager(this);mLinearLayoutManager1.setOrientation(OrientationHelper.HORIZONTAL);recyclerView1.setLayoutManager(mLinearLayoutManager1);recyclerView1.setAdapter(mAdapter);

设置数据部分：

mAdapter.setContacts(listResult);mAdapter.notifyDataSetChanged();

总结：项目中会出现很多种情况，一种是这样的：

图1：（附：布局可以复用类型，这样赋值的时候不需要判断布局的子布局，统一id）

另一种就是完全不同的布局：举个例子：

图2：（附其实这个也是相同的，大家假装不同~么么哒~）

好累~遇到问题的时候自己看着写吧~我只是记录自己的需求，以后留着用~大家自己参考~睡觉去了~
