我正在使用共享首选项编辑器来存储数字以保存并在我的项目中的另一个类中使用，这是我保存数据的来源：

public void overallEditor(){
        SharedPreferences.Editor editor = someData.edit();
        editor.putInt("winsOverall", winsOverall);
        editor.putInt("losesOverall", losesOverall);
        editor.putInt("tiesOverall", tiesOverall);
        editor.commit();
    }

这是我检索数据的来源：

private void getStats() {
        // TODO Auto-generated method stub
        SharedPreferences someData = getSharedPreferences(filename, 0);
        bestStreakStatsi = someData.getInt("newBestStreak", 0);
        winsOverall = someData.getInt("winsOverall", 0);
        tiesOverall = someData.getInt("tiesOverall", 0);
        losesOverall = someData.getInt("losesOverall", 0);
    }

怎么了

在此处输入图像描述

这是我第一堂课的资料，如果你需要我的资料，我可以提供，但我删掉了不相关的内容：

int wins, ties, loses, choice, streak, bestStreak, z, winsOverall, losesOverall, tiesOverall;

    private void refresh(){
            winrep.setText(w + wins);
            loserep.setText(l + loses);
            tierep.setText(t + ties);
            SharedPreferences.Editor editor = someData.edit();
            editor.putInt("winsp", wins);
            editor.putInt("losesp", loses);
            editor.putInt("tiesp", ties);
            editor.putInt("streakp", streak);
            editor.commit();
            overallEditor();
        }
        public void overallEditor(){
            SharedPreferences.Editor editor = someData.edit();
            editor.putInt("winsOverall", winsOverall);
            editor.putInt("losesOverall", losesOverall);
            editor.putInt("tiesOverall", tiesOverall);
            editor.commit();
        }

这是它应该检索整数的地方：

public class stats extends Activity{
    public static String filename = "stats";
    TextView bestStreakStats, overallWins, overallLoses, overallTies;
    int bestStreakStatsi, winsOverall, losesOverall, tiesOverall;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.stats);
        initizialize();
        getStats();
        displayStats();
    }
    private void displayStats() {
        // TODO Auto-generated method stub
        bestStreakStats.setText("You best winning streak: \t" + bestStreakStatsi);
        overallWins.setText("Your overall wins: \t" + overallWins);
        overallLoses.setText("Your overall loses: \t" + overallLoses);
        overallTies.setText("Your overall ties: \t" + overallTies);
    }
    private void getStats() {
        // TODO Auto-generated method stub
        SharedPreferences someData = getSharedPreferences(filename, 0);
        bestStreakStatsi = someData.getInt("newBestStreak", 0);
        winsOverall = someData.getInt("winsOverall", 0);
        tiesOverall = someData.getInt("tiesOverall", 0);
        losesOverall = someData.getInt("losesOverall", 0);
    }
    private void initizialize() {
        // TODO Auto-generated method stub
        bestStreakStats = (TextView) findViewById(R.id.tvBestStreakStats);
        overallWins = (TextView) findViewById(R.id.tvOverallWins);
        overallLoses = (TextView) findViewById(R.id.tvOverallLoses);
        overallTies = (TextView) findViewById(R.id.tvOverallTies);
    }
}

发生这种情况的原因很可能是因为您正在这样做

[TextView Object].getText();

这是不正确的，应该是：

[TextView Object].getText().toString();

更新

你真的需要修正你的命名约定。发生这种情况的原因是您在 displayStats() 方法中显示了错误的对象。

对于一些建议，我会为您的 TextViews 推荐这种命名约定

TextView tx_[somename];

和你的价值观

int value_[somename]

我认为您的问题是您引用了错误的变量。你是说。

overallWins.setText("Your overall wins: \t" + overallWins);

但我认为应该是：

overallWins.setText("Your overall wins: \t" + winsOverall);

其余部分也是如此.setText。看看是否有帮助。
