因此，对于我正在开发的应用程序，我想使用 sharedpreferences 来保存数据，在这种情况下，我想保存用户选择的语言。这是由 A 号完成的，它会保存它，但是当我尝试在我的菜单页面上使用这个值时，它总是崩溃

super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main_menu);
    Button button1 = (Button) findViewById(R.id.button1);
    Button button2 = (Button) findViewById(R.id.button2);
    Button button3 = (Button) findViewById(R.id.button3);
    Button button4 = (Button) findViewById(R.id.button4);
    Button button5 = (Button) findViewById(R.id.button5);
    SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(this);
    int taal=sp.getInt("taal", 4);
    if(taal==1){
        String tekst="Nieuw Spel";
        button1.setText(tekst);
        //button1.setText("Nieuw Spel");
        //button2.setText("Statestieken");
        //button3.setText("Opties");
        //Languege.MenuText(button1, button2, button3, taal);
        button1.setText(taal);
        button4.setVisibility(Button.GONE);
        button5.setVisibility(Button.GONE);
    }

这又回到了错误的屁股上，我真的找不到我做错了什么

改变

button1.setText(taal);

所以它是

button1.setText(String.valueOf(taal));

通过传递一个整数 ( taal)，Android 会尝试查找资源 id 并失败。
