android - sharedpreferences 保存但在 if 语句上崩溃

Question

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。这是通过一个数字完成的，它会保存这个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);
    }

这会返回错误，但我真的找不到我哪里做错了

Answer 1

改变

button1.setText(taal);

原来如此

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

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