Question

我正在设计一款有效的游戏，直到我在主要活动中添加了保存分数的功能。一旦我做了，分数保存工作，但在每个最后阶段，游戏崩溃与以下错误代码：

这就是我保存的结构：在游戏结束时（由游戏类中的boolean gameOver表示），我的处理程序会收到通知，然后从游戏类中提取得分，然后使用saveScore方法保存SharedPreferences。

我不确定为什么它会崩溃，但保持最新的保存分数。上面提到的代码如下所示：

MainActivity：

Handler timerHandler = new Handler();
Runnable timerRunnable = new Runnable() {public void run() {if (Game.getGameOver())
            saveScore(Game.getScore());
        timerHandler.postDelayed(this, 1);
    } };
 public void saveScore(int score)

{
    if (score>getSharedPreferences("myPrefsKey", 0).getInt("key",0))
    {SharedPreferences prefs = getSharedPreferences("myPrefsKey", 0);
    SharedPreferences.Editor editor = prefs.edit();
    editor.putInt("key", score);
    editor.commit();}
    scoreTextView.setText(getSharedPreferences("myPrefsKey", 0).getInt("key",0));
}
 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Game= (Game)findViewById(R.id.Game_canvas);
        timerTextView = (TextView) findViewById(R.id.text1);
        scoreTextView = (TextView) findViewById(R.id.text2);
        scoreTextView.setText(getSharedPreferences("myPrefsKey", 0).getInt("key", 0)
                    timerHandler.postDelayed(timerRunnable, 0);
    }

GameClass（扩展视图）

private boolean gameOver=false;

public boolean getGameOver()
{


    if (condition) {
        gameOver = true;
    }
    else
    gameOver=false;
    return gameOver;
}
public int getScore()
{

    return score;
}

非常感谢!!!

编辑：我再次运行它，这是以下消息

我怀疑它可能只是没有在strings.xml中为SharedPreferences定义String。我会检查一下。 NVM。它没有用。

编辑：错误是尝试将int传递给字符串。

结束游戏时的Android游戏崩溃（NullPointerException）
