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/图标集并且可以随机化主菜单按钮的菜单，我让一切正常，然后我开始开发介绍屏幕，该屏幕在用户首次使用 Dialog 启动应用程序时启动框，现在当用户选择不同的方案时，我的颜色会动态变化，效果很好，当用户来到框时，它会询问他们是否每次都要随机化菜单按钮的颜色：

如果我点击 Randomize 它确实会动态变化，但如果我勾选顺序然后它根本不会改变，我不明白。

我有 3 个主要文件：ConversePrefs.java，我不会发布它，因为我 100% 确定它是正确的，因为它只是一组用于获取共享首选项的快捷功能。

MainMenu.java - 主要活动/主菜单：

ColorCollections.java - 包含颜色信息/和一些检索功能的文件。

package com.arl.conversion;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.Collections;
import java.util.List;

import android.app.Application;
import android.content.Context;
import android.content.SharedPreferences;
import android.util.Log;

public class ColorCollections{
     Context context;
     public ColorCollections(Context context){
            this.context = context;
        }
    //Color Palettes.
    public static String[] Win8 = new String[]{"#008299","#00A0B1","#2672EC","#2E8DEF","#8C0095","#A700AE","#5133AB","#643EBF","#AC193D","#BF1E4B","#D24726","#DC572E","#008A00","#00A600","#094AB2","#0A5BC4"};
    public static String[] ModernUrban = new String[]{"#47B6BE","#73CC3E","#FF7149","#FF5063","#FF6999","#233977","#4B9364","#8A8F1D","#A63B52","#B23265","#883E57","#888788","#87A087"};

    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:
            themeID = R.layout.activity_main_menu_light;
            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;
    }

}

有人可以找出问题吗？在过去的 2 个小时里，我一直坚持这个问题，并且尝试了所有方法，甚至最终获得了效率更高的代码（我知道这对你来说可能看起来很糟糕，但更糟糕的是，相信我）。

另外我有4组图标，每组12个图标，每组都有图标前缀，它是一个实际导入的可绘制.png。有没有比手动输入更好的方法来创建它们的 XML 列表？

谢谢你。

我无法找到问题的确切位置，但如果您还没有找到问题的具体位置，那么进行调试会有所帮助，然后开始使用 setSingleChoiceItems(...) 函数。您可以使用 ListView 来显示 XML 列表。这是从 strings.xml 文件生成的示例：http ://www.androidhive.info/2011/10/android-listview-tutorial/ 。更复杂的 ListView 将需要您创建自定义适配器类。
