根据后台数据，动态添加Recycleview+headview

外部布局LinearLayout videoreLayout
titles， Recycleview headview 标题名称

videoreLayout.removeAllViews();
for(int i =0 ;i<titles.size();i++){
       RecyclerView recyclerView = new RecyclerView(getContext());
       RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
       layoutParams.leftMargin = DensityUtil.dip2px(getContext(), 15);
       layoutParams.rightMargin = DensityUtil.dip2px(getContext(), 15);
       recyclerView.setLayoutParams(layoutParams);


List<XxxBean> typeList = new ArrayList<>();
JSONArray jsonArray = jinshanyunData.getJSONArray(titles.get(i)/*根据标题拿当前recycleview数据源,根据后台返回的json结构自由修改*/);
for (int j = 0; j < jsonArray.length(); j++) {
    JSONObject jsonObject1 = (JSONObject) jsonArray.get(j);
    String name = jsonObject1 .getString("name");
    ...//后续自己根据数据结构添加
typeList.add(new XxxBean(name,...))
}
 XXXAdapter xxxAdapter= new XXXAdapter (getActivity(), typeList);
xxxAdapter.setOnItemClickListener(new XXXAdapter .OnItemClickListener() {
                                    @Override
                                    public void onItemClick(int position) {
                                        Log.e("info", "点击第" + position + "个");
                                        
                                    }
                                });
 recyclerView.setAdapter(xxxAdapter);

                                recyclerView.addItemDecoration(twodecoration/*分割距离**/);
                                recyclerView.setLayoutManager(/*recycleview 布局manager 
 上面自己new就行**/);
                                View view = View.inflate(getContext(), R.layout.head_item, null);
                                ImageView xxxtagImageView = view.findViewById(R.id.videorecommend_newtag);//recycleview标题布局的图案
                                xxxtagImageView .setTag(i);
xxxtagImageView .setOnClickListener(new View.OnClickListener() {
                                    @Override
                                    public void onClick(View v) {
                                        int i1 = (int) v.getTag();
                                        //标题的点击事件
                                    }
                                });

 videoreLayout.addView(view);
videoreLayout.addView(recyclerView);
}

只是一次动态添加recycleview+headview，然后添加到布局，如果有性能问题或者有其他优化方式，感谢提醒
