Java如何获取JsonObject中包含JSONArray的特定值的集合(列表)

Question

我是 Java 新手，我有一个 javabeans conatins

class Players{
@SerializedName("status")
@Expose
private String status;

@SerializedName("teamOne")
@Expose
private List<TeamOne> teamOne;

@SerializedName("teamTwo")
@Expose
private List<TeamTwo> teamTwo;

public String getStatus() {return status);}
public void setStatus(String status) {this.status = status;}

public List<TeamOne> getTeamOne(){ return teamOne:}
public setTeamOne(List<TeamOne> teamOne){ this.teamOne= teamOne:}

public List<TeamTwo> getTeamTwo(){ return teamTwo:}
public setTeamTwo(List<TeamTwo> teamTwo){ this.teamTwo= teamTwo;}

}

class TeamOne {
 @SerializedName("winningScore")
@Expose
private String winningScore;

@SerializedName("playerName")
@Expose
private String PlayerName;
}

class TeamTwo {
 @SerializedName("winningScore")
@Expose
private String winningScore;

@SerializedName("playerName")
@Expose
private String PlayerName;
}

我的 json 返回看起来像

{
"status":"BestPlayers",
"teamOne":[
   {
   "winningScore":"11",
   "playerName":"John"
   },
   {
   "winningScore":"11",
   "playerName":"David"
   }
],
"teamTwo":[
  {
   "winningScore":"15",
   "playerName":"Victor"
  },
 {
  "winningScore":"15",
  "playerName":"Thomas"
  }
]
}

现在我正在尝试获取两支球队的球员姓名列表。看起来应该是 [John, David, Victor,Thomas]

我尝试了一个 while 循环，它可以循环数组上的数字，但无法做到这一点，但我只得到第一个玩家的名字，仅此而已，我什至无法到达第二个团队数组。我非常感谢您的帮助。

需要有关此代码的帮助

问题在于您的 POJO 模型类，它应该是 TeamDetails 或 Team

    class Players{
    @SerializedName("status")
    @Expose
    private String status;
    @SerializedName("teamOne")
    @Expose
    private List<Team> teamOne;

    @SerializedName("teamTwo")
    @Expose
    private List<Team> teamTwo;
}


  class Team {
     @SerializedName("winningScore")
    @Expose
    private String winningScore;

    @SerializedName("playerName")
    @Expose
    private String PlayerName;
    }

现在创建一个最终的玩家列表，例如

private getTotalList(){
    List<Team> finalTeams=new ArrayList()
if(null!=teamOne && teamOne.size()>0){ // thats how your requirment will work
    finalTeams.add(teamOne)
}
//same goes for all teams add null check and add them.
 if(null!=teamTwo && teamTwo .size()>0){ // thats how your requirment will work
    finalTeams.add(teamTwo)
}



if(null!=funLovers && funLovers .size()>0){ 
        finalTeams.add(funLovers)
    }

        return finalTeams:
     }

然后使用foreach循环

for(Team  team: finalTeams){
Log.d("playerName: ", team.PlayerName)
}
