Question

我有一个名为Score的对象，我在ArrayAdapter中使用它。如何调用其中定义的函数？以下是我的主要活动，包括我试图解决的问题。

public class ScoreList extends Activity {

    private ListView listViewScore;
    private Context ctx;

    ArrayList<Integer> allScoreChange = new ArrayList<Integer>();
    ArrayList<Integer> allScore = new ArrayList<Integer>(); 

    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.score_list);
        ctx = this;
        final List<Score> listScore = new ArrayList<Score>();
        listScore.add(new Score("Player A", "0", "0"));
        listScore.add(new Score("Player B", "0", "0"));
        listScore.add(new Score("Player C", "0", "0"));

        for(int i = 0; i < listScore.size(); i++)
        {
            allScoreChange.set(i,0);
            allScore.set(i,listScore.getScoreTotal(i)); // this is the line I'm working on
        }
    }

}

以下是带有该功能的Score对象本身。

public class Score {

    private String name;
    private String scoreChange;
    private String scoreTotal;

    public Score(String name, String scoreChange, String scoreTotal) {
        super();
        this.name = name;
        this.scoreChange = scoreChange;
        this.scoreTotal = scoreTotal;
    }

    public String getScoreTotal() {
        return scoreTotal;
    }

}

Answer 1

allScore.set(i,listScore.getScoreTotal(i)); // this is the line I'm working on

使用列表的get()方法：

allScore.set(i, listScore.get(i).getScoreTotal());

（技术上，listScore是List而不是ArrayAdapter。）

如何从主活动中调用ArrayAdapter对象的函数？
