Android ArrayList复制条目？

在我的应用程序中，我有一个包含JSONArray到JSONObject的JSON。我用JSONArray获取了这些JSONObject，生成了一个对象Batalha，还获取了JSONArraybadges并添加到对象BadgesGanha中。在对象Batalha中，我有一个添加对象BadgeGanha的列表

现在我尝试在对象Batalha中打印列表的大小，问题是打印一个重复的值，例如，如果在logcat print 6中列表的大小为3。我不明白为什么会有这个问题

JSON

豆子

创建列表并显示列表的大小

我解决了这个问题

我换了块徽章，现在可以工作了

//badges
JSONArray arrayBadges = jsObj.getJSONArray("badges");
List<BadgesGanha> lista = new ArrayList<BadgesGanha>();
for(int i = 0; i < arrayBadges.length(); i++){
    JSONObject jsBadges = arrayBadges.getJSONObject(i);
    BadgesGanha badge = gson.fromJson(jsBadges.toString(), BadgesGanha.class);
    lista.add(badge);
    batalha.setBadges(lista);
}

public class Batalha implements Serializable{
    private static final long serialVersionUID = 1L;

    @SerializedName("ID")
    private Long id;

    private String player1;
    private String player2;
    private String data_inicio;
    private String data_fim;
    private int status;
    private int ID_arena;
    private String vez_player;
    private String player_vencedor;

    private List<BadgesGanha> badges = new ArrayList<BadgesGanha>();


    public Batalha() {    
    }


    /** add badges ganha */
    public void addBadgesGanha(BadgesGanha badge){
        badges.add(badge);
    }



public class BadgesGanha implements Serializable{
    private static final long serialVersionUID = 1L;

    @SerializedName("ID")
    private Integer id;

    private String email;
    private Integer ID_batalha;
    private Integer ID_arena;
    private Integer status;

Gson gson = new Gson();
JSONObject objRetorno = obj.getJSONObject("retorno");

/** abertas */
JSONObject objBatalhas = objRetorno.getJSONObject("batalhas");
JSONArray arrayAberto = objBatalhas.getJSONArray("aberto");
List<Batalha> listBatalhaAberta = new ArrayList<Batalha>();

//batalha aberta
for(int x = 0; x < arrayAberto.length(); x++){
    //pega batalha
    JSONObject jsObj = arrayAberto.getJSONObject(x);
    Batalha batalha = gson.fromJson(jsObj.toString(), Batalha.class);

    //pega badges
    JSONArray arrayBadges = jsObj.getJSONArray("badges");
    for(int i = 0; i < arrayBadges.length(); i++){
        JSONObject jsBadge = arrayBadges.getJSONObject(i);
        BadgesGanha badge = gson.fromJson(jsBadge.toString(), BadgesGanha.class);
        //add badge batalha
        batalha.addBadgesGanha(badge);
    }
    //create list of Batalha
    listBatalhaAberta.add(batalha);
}

//print size list List<BadgesGanha>
for(Batalha x : listBatalhaAberta){
   //should print 3 badges but print 6 badges
   Log.i("BADGES LISTBATALHAABERTA-> ", x.getBadges().size() + "");
}

//badges
