}初始化部分：
//TODO mAdapter = 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~
