Android 使用共享首选项在活动之间传递整数

我正在尝试将这个

分数

整数从一个活动传递到另一个活动。我在分享偏好方面遇到了困难。在MainActivity中，我没有收到任何警告或错误，但在ScoreActivity中，我收到一个错误，表示类型共享首选项中的方法getInt（String，int）不适用于参数（long，int）。我该如何解决这个问题

main活动

private int SCORE = 0;


@Override
protected void onCreate (Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    SharedPreferences sharedPref = getPreferences(Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = sharedPref.edit();
    editor.putInt("SCORE", SCORE);
    editor.commit();

评分活动

private int SCORE = 0;

@Override
protected void onCreate (Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_score);


    SharedPreferences sharedPref = getPreferences(Context.MODE_PRIVATE);
    int defaultValue = getResources().getInteger(SCORE);
    long SCORE = sharedPref.getInt(SCORE, defaultValue);

这个

应该是

int SCORE = sharedPref.getInt("SCORE", defaultValue); 
//"SCORE" is the key
// return's a int value not long

请尝试从设备卸载应用程序，然后重试…@Lal由于上述错误，它将无法编译。
