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：
