Question

所以在我正在制作的游戏中，我正在使用SharedPreferences来保存我的数据，但是它不会保存我的数据或恢复它（一个或两个）。（是的，我知道使用double.valueOf()是低效的，但现在不是问题）

这是我的onCreate（我获取所有已保存的数据）

       public int hasPlayed = 0;
public double $money;
public int $isonmainpage = 1;
Random random = new Random();
public int $cantafford = 0;
public double $employertimer;
public double $employercounter;

public double $employeeupgrade1earnings;
public double $employeeupgrade1cost = 1;
public double $employeeupgrade1level;


public double $employerupgrade1level;
public double $employerupgrade1earnings;
public double $employerupgrade1cost = 1;
public double $allupgrades;
public String version = "0.0.1";
;


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    SharedPreferences sharedpreferences = getSharedPreferences("MyPrefs", Context.MODE_PRIVATE);
    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);
    SharedPreferences.Editor editor = sharedpreferences.edit();
    hasPlayed = sharedpreferences.getInt("hasPlayed", 1);
    sharedpreferences.getAll();

    if (hasPlayed == 1){
        $money = Double.valueOf(sharedpreferences.getString("money", (Double.toString($money))));
        $employercounter = Double.valueOf(sharedpreferences.getString("employercounter", (Double.toString($employercounter))));
        $employerupgrade1earnings = Double.valueOf(sharedpreferences.getString("employerupgrade1earnings", (Double.toString($employerupgrade1earnings))));
        $employerupgrade1level = Double.valueOf(sharedpreferences.getString("employerupgrade1level", (Double.toString($employerupgrade1level))));
        $employerupgrade1cost = Double.valueOf(sharedpreferences.getString("employerupgrade1cost", (Double.toString($employerupgrade1cost))));
        $employeeupgrade1level = Double.valueOf(sharedpreferences.getString("employeeupgrade1level", (Double.toString($employeeupgrade1level))));
        $employeeupgrade1earnings = Double.valueOf(sharedpreferences.getString("employeeupgrade1earnings", (Double.toString($employeeupgrade1earnings))));
        $employeeupgrade1cost = Double.valueOf(sharedpreferences.getString("employeeupgrade1cost", (Double.toString($employeeupgrade1cost))));
    }
    if (hasPlayed == 0) {
        hasPlayed = 1;
        editor.putInt("hasPlayed", 1);
        editor.commit();
    }
    updatemoney();
    timer();

}

这是我的onStop / onPause（当我保存数据时）

@Override
protected void onPause() {
    super.onPause();
    SharedPreferences sharedpreferences = getPreferences(MODE_PRIVATE);
    SharedPreferences.Editor editor = sharedpreferences.edit();
    editor.putString("money", (Double.toString($money)));
    editor.putString("employercounter", (Double.toString($employercounter)));
    editor.putString("employerupgrade1earnings", (Double.toString($employerupgrade1earnings )));
    editor.putString("employerupgrade1level", (Double.toString($employerupgrade1level)));
    editor.putString("employerupgrade1cost", (Double.toString($employerupgrade1cost)));
    editor.putString("employeeupgrade1level", (Double.toString($employeeupgrade1level)));
    editor.putString("employeeupgrade1earnings", (Double.toString($employeeupgrade1earnings)));
    editor.putString("employeeupgrade1cost", (Double.toString($employeeupgrade1cost)));
    editor.commit();
}

@Override
protected void onStop() {
    super.onStop();
    SharedPreferences sharedpreferences = getPreferences(MODE_PRIVATE);
    SharedPreferences.Editor editor = sharedpreferences.edit();
    editor.putString("money", (Double.toString($money)));
    editor.putString("employercounter", (Double.toString($employercounter)));
    editor.putString("employerupgrade1earnings", (Double.toString($employerupgrade1earnings )));
    editor.putString("employerupgrade1level", (Double.toString($employerupgrade1level)));
    editor.putString("employerupgrade1cost", (Double.toString($employerupgrade1cost)));
    editor.putString("employeeupgrade1level", (Double.toString($employeeupgrade1level)));
    editor.putString("employeeupgrade1earnings", (Double.toString($employeeupgrade1earnings)));
    editor.putString("employeeupgrade1cost", (Double.toString($employeeupgrade1cost)));
    editor.commit();
}

编辑：我永远不会去了解为什么我被贬低如果我不被告知为什么我被投票。感谢

Answer 1

替换

SharedPreferences savefile = getPreferences(MODE_PRIVATE);

与

SharedPreferences  sharedpreferences = getSharedPreferences("MyPrefs", Context.MODE_PRIVATE);

并关注this link

Answer 2

我想应该是因为这个 hasplayed和hasPlayed，密钥应区分大小写

savefile.getInt("hasplayed", 0);

editor.putInt("hasPlayed", 1);

SharedPreferences不保存我的数据
