Java 如何从弹出窗口接受用户输入？

我是android新手，刚刚处于学习阶段，有一个问题，如果你能回答，那就太好了

我尝试制作的第一个应用程序是关于计算分数的，它还有一个记分板页面，显示哪个球员得分多少。我想做的是在运行时接受玩家的名字，可能使用弹出窗口，一旦玩家1退出，再次弹出窗口以获取第二个玩家的名字

代码如下：

活动记分牌：

<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/list_of_players"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.android.cricketcounter.Scoreboard">

</ListView>

PlayerAdapter.java：

package com.example.android.cricketcounter;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;

import java.util.ArrayList;

public class PlayerAdapter extends ArrayAdapter<Players> {

    public PlayerAdapter(Context context, ArrayList<Players> players){
        super(context, 0, players);
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View listItemView = convertView;
        if (listItemView == null) {
            listItemView = LayoutInflater.from(getContext()).inflate(
                    R.layout.list_item, parent, false);
        }

        Players currentPlayer = getItem(position);

        TextView playerName = (TextView) listItemView.findViewById(R.id.name);
        playerName.setText(currentPlayer.getPlayerName());

        TextView runsScored = (TextView) listItemView.findViewById(R.id.runsA);
        runsScored.setText(String.valueOf(currentPlayer.getRuns()));

        TextView ballsTaken = (TextView) listItemView.findViewById(R.id.ballsA);
        ballsTaken.setText(String.valueOf(currentPlayer.getBalls()));

        return listItemView;
    }
}

公共类PlayerAdapter扩展了ArrayAdapter{
公共玩家适配器（上下文、ArrayList玩家）{
超级（上下文，0，玩家）；
}
@凌驾
公共视图getView（int位置、视图转换视图、视图组父视图）{
View listItemView=convertView；
如果（listItemView==null）{
listItemView=LayoutFlater.from（getContext（））.inflate(
R.layout.list_项，父项，false）；
}
玩家currentPlayer=getItem（位置）；
TextView playerName=（TextView）listItemView.findViewById（R.id.name）；
playerName.setText（currentPlayer.getPlayerName（））；
TextView runsCord=（TextView）listItemView.findViewById（R.id.runsA）；
runsScored.setText（String.valueOf（currentPlayer.getRuns（））；
TextView-ballsTaken=（TextView）listItemView.findViewById（R.id.ballsA）；
setText（String.valueOf（currentPlayer.getBalls（））；
返回listItemView；
}
}

取决于您如何使用Popuscure，这是一种方法，->当玩家离开时，dialogbox获取玩家姓名->根据需要将该姓名存储在数据库列表中，然后

notifyDataSetChanged（）
