总结一个recyclerview使用模版

rvRecommend = (RecyclerView) findViewById(R.id.activity_academy_video_rv_recommend);
rvRecommend.setLayoutManager(new LinearLayoutManager(this));//纵向
//rvPhoto.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false));横向
//rvAnswerSheet.setLayoutManager(new GridLayoutManager(this, 5));宫格     //academyVideoDetailAdapter.setOnRecommendItemClickListener(this);点击事件
rvRecommend.setAdapter(academyVideoDetailAdapter);
//记得new一个adapter
