我正在Android Studio上使用Firebase数据库。代码Java。我使用实时数据库。 我正在做一个聊天应用。我想向用户显示收件箱中的最后一封邮件。

我有这个数据库：

message: {
       User uıd: {
                Uid of the person he is talking to: {  
                   random key: {
                        -date
                        -from
                        -message
                        -time
                        -type
                       }
                    }
                }

我引用了数据库als：

mAuth = FirebaseAuth.getInstance();
currentUserID = mAuth.getcurrentUser().getUid();
Chatsref=FirebaseDatabase.getInstance().getReference().child("message").child(currentUserID);

我正在使用它来获取：

  public void messageegetir(){
        FirebaseRecyclerOptions<Messages> options =
                new FirebaseRecyclerOptions.Builder<Messages>()
                        .setQuery(Chatsref,Messages.class)
                        .build();

        FirebaseRecyclerAdapter<Messages,ChatsViewHolder> adapter =
                new FirebaseRecyclerAdapter<Messages,ChatsViewHolder>(options) {
                    @Override
                    protected void onBindViewHolder(@NonNull final ChatsViewHolder holder,final int position,@NonNull final Messages model) {
                        final String usersIDs = getRef(position).getKey();
                        final String[] retImage = {"default_image"};

                    }

                    @NonNull
                    @Override
                    public ChatsViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup,int i) {
                        View view = LayoutInflater.from(viewGroup.getcontext()).inflate(R.layout.message_list_model,viewGroup,false);
                        return new ChatsViewHolder(view);
                    }
                };

        chatlist.setadapter(adapter);
        adapter.startListening();
        updateUserStatus("online");
    }

我的公共统计类：

public static class ChatsViewHolder extends RecyclerView.ViewHolder{

        CircleImageView profileImage ;
        ImageView onlinestatus;
        TextView lastmessage,username ;

        public ChatsViewHolder(@NonNull View itemView) {
            super(itemView);

            profileImage =itemView.findViewById(R.id.messageprofileimageee);
            username =itemView.findViewById(R.id.messagenameee);
            lastmessage =itemView.findViewById(R.id.messageinfooo);
            onlinestatus =itemView.findViewById(R.id.onlinestatus);
        }
    }

消息类：

public class Messages {
    public String data,time,type,message,from  ;

    public Messages(){

    }

    public Messages(String data,String time,String type,String message,String from) {
        this.data = data;
        this.time = time;
        this.type = type;
        this.message = message;
        this.from = from;
    }

    public String getData() {
        return data;
    }

    public void setData(String data) {
        this.data = data;
    }

    public String getTime() {
        return time;
    }

    public void setTime(String time) {
        this.time = time;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public String getFrom() {
        return from;
    }

    public void setfrom(String from) {
        this.from = from;
    }
}

如何获取这些数据并将其写入textview？
