共享参数不能保存的问题

我想保存一个共享参数，然后重新启动应用程序。但是它并不能保存，也没加载正确的值。代码是这样的：

int punkteint = 0;
TextView test1;
String points;
private static String SHARED_PREF_ID = "0";

public void onCreate(Bundle savedInstanceState) {
    test1 = (TextView) findViewById(R.id.test1);
    SharedPreferences load = getSharedPreferences(SHARED_PREF_ID, 0);
    points = load.getString("punkte", "0");
    points = SHARED_PREF_ID;
    test1.setText(points);
    mehrPunkte();
    }


public void mehrPunkte() {

    punkteint++;

    SHARED_PREF_ID = Integer.toString(punkteint);
    SharedPreferences load = getSharedPreferences(SHARED_PREF_ID, MODE_PRIVATE);
    points = load.getString("punkte", "0");
    points = SHARED_PREF_ID;
    test1.setText(points);

    SharedPreferences save = getSharedPreferences(SHARED_PREF_ID, MODE_PRIVATE);
    save.edit().putString("punkte", SHARED_PREF_ID).commit();
}

出现的错误请求指点，谢谢!

SharedPreferences.Editor prefEditor = save.edit();
prefEditor.putString("blah", blah);
PredEditor.commit()

在onPause保存，在onResume上加载.
