android - RecyclerView 展开/折叠

Question

1. 当我单击 RecyclerView 的一项时，我想展开/折叠如下图所示的内容。
2. 这与新的 Android 最近通话记录列表的效果相同。选项“CALL”和“DETAILS”或“SEND MESSAGE”仅在选择项目时可见。
3. 图片： 图片

4. 这是我的RecyclerViewAdapter类，非常感谢：

   公共类 RecyclerViewAdapter 扩展 RecyclerView.Adapter { Context mContext; 列出 mData；

   public RecyclerViewAdapter(Context mContext, List<Contact> mData) {
       this.mContext = mContext;
       this.mData = mData;
   }
   
   @NonNull
   @Override
   public MyViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
       View v;
       v = LayoutInflater.from(mContext).inflate(R.layout.item_contact, viewGroup, false);
       MyViewHolder viewHolder = new MyViewHolder(v);
   
       return viewHolder;
   }
   
   @Override
   public void onBindViewHolder(@NonNull MyViewHolder myViewHolder, final int position) {
       myViewHolder.tvName.setText(mData.get(position).getName());
       myViewHolder.tvFname.setText(mData.get(position).getFname());
       myViewHolder.img.setImageResource(mData.get(position).getPhoto());
   }
   
   @Override
   public int getItemCount() {
       return mData.size();
   }
   
   public static class MyViewHolder extends RecyclerView.ViewHolder{
   
       private TextView tvName;
       private TextView tvFname;
       private ImageView img;
   
       public MyViewHolder(@NonNull View itemView) {
   
           super(itemView);
           tvName = (TextView)itemView.findViewById(R.id.tvName);
           tvFname = (TextView)itemView.findViewById(R.id.tvFname);
           img = (ImageView)itemView.findViewById(R.id.img_contact);
       }
   }
   

   }
