Android Dev：我的函数有问题，但我被卡了两个小时

Question

所以我正在制作我的第二个应用程序，我决定构建一个具有多个皮肤/图标集并可以随机化主菜单按钮的菜单，我完成了所有工作，然后我开始开发简介屏幕，该屏幕在用户第一次使用对话框启动应用程序时启动，现在当用户选择不同的方案时，颜色会动态变化，效果很好，当用户来到询问是否每次都要随机化菜单按钮颜色的框时：

如果我点击随机化，它确实会动态变化，但如果我按顺序勾选，它根本不会改变，我就不明白

我有三个主要文件：ConversePrefs.java，我不会发布它，因为我100%确信它是正确的，因为它只是一组用于获取共享偏好的快捷函数。

MainMenu.java-主活动/主菜单：

ColorCollections.java-包含有关颜色的信息的文件，并且很少有可供检索的函数。

     public ColorCollections(Context context){
            this.context = context;
        }
    //Color Palettes.

    public List<String> GetColorList(int colorindex, boolean randomizer){
        List<String> colorList = Arrays.asList(Win8);
        switch(colorindex){
        case 0:
            colorList = Arrays.asList(Win8);
            break;
        case 1:
            colorList = Arrays.asList(ModernUrban);
            break;
        }
        if(randomizer == true){
            Collections.shuffle(colorList);
            Collections.shuffle(colorList);
            Collections.shuffle(colorList);
            Collections.shuffle(colorList);
        }
        return colorList;
    }
    public int GetTheme(int theme){
        int themeID = 0;
        switch(theme){
        case 0:

            break;
        case 1:
            themeID = R.layout.activity_main_menu_light_bg;
            break;
        case 2:
            themeID = R.layout.activity_main_menu_dark;
            break;
        case 3:
            themeID = R.layout.activity_main_menu_dark_bg;
            break;
        }       
        return themeID;
    }
}

有人能找出问题吗？在过去的两个小时里，我一直被这个问题困扰着，并尝试了所有的东西，甚至最终得到了效率更高的代码（我知道这对你来说可能很糟糕，但更糟糕，相信我）。

此外，我有4组图标，每组12个图标，每组都有图标前缀，这是一个实际导入的drawable.png。有没有比手动键入更好的方法来创建它们的XML列表？

谢谢。

我找不到问题的确切位置，但如果你还没有找到，那么进行调试对你来说是有益的，首先进入setSingleChoiceItems（…）函数。您可以使用ListView来显示XML列表。下面是一个从strings.xml文件生成的示例：http://www.androidhive.info/2011/10/android-listview-tutorial/。更复杂的ListViews将需要您创建一个自定义适配器类。
