问题排查与解决方案

嘿，我一眼就揪出问题所在了——你的player_object.java里的成员变量全都被声明成static了！

问题根源

static变量属于类本身，而非类的实例。这意味着你创建的所有player_object对象都会共享这四个变量的值。当你在循环里逐个创建玩家对象时，每一次赋值都会覆盖掉之前的数值，最后所有对象都会持有最后一个玩家的数据，RecyclerView自然就重复显示同一组信息了。

解决方案

把player_object里的static修饰符全部去掉，让它们成为每个实例独有的成员变量：

public class player_object { 
    private String gamer; 
    private int points; 
    private int photos; 
    private int highscore; 

    public player_object(String gamer, int points, int photos, int highscore) { 
        this.gamer = gamer; 
        this.points = points; 
        this.photos = photos; 
        this.highscore = highscore; 
    } 

    public String getPlayer(){ 
        return gamer; 
    } 

    public int getPoints(){ 
        return points; 
    } 

    public int getPhotos(){ 
        return photos; 
    } 

    public int getHighscore(){ 
        return highscore; 
    } 

    public void setPlayer(String gamer){ 
        this.gamer = gamer; 
    } 

    public void setPoints(int points){ 
        this.points = points; 
    } 

    public void setPhotos(int photos){ 
        this.photos = photos; 
    } 

    public void setHighscore(int highscore){ 
        this.highscore = highscore; 
    } 
}
