如何洗牌两个不同的数组列表值有两个的ArrayList出切换顺序

Question

喜的朋友我感到有两个的ArrayList一个是图像的ArrayList，另外一个声音ArrayList中，我不得不放弃背景imageviews随机使用图像arrylist，当我点击那个图像，我需要播放该图像相关的声音，这两个arraylists我现在正在shuffling，我可以随机设置图像背景，但我的问题是在声音，洗牌后声音播放错误，如果'a'图像意味着它播放'c'听起来有些时候开始播放b听起来etc..how解决这个任何一个建议我

创建图片和音乐的Pair（或更好的自己的类），把它们放到列表和洗牌了。

List<Pair<Integer, Integer>> pics = new ArrayList<Pair<Integer, Integer>>(); 
pics.add(new Pair<Integer, Integer>(R.drawable.a_white, R.raw.a)); 
... 
Collections.shuffle(pics); 

image1.setBackgroundResource(pics.get(0).first) 

P.S.你有很多重复的代码。例如，将Pair添加到imageView作为标记。

pict = pics.get(0); 
image1.setBackgroundResource(pict.first); 
image1.setTag(pict); 

然后在clickListener：

Pair<Integer, Integer> pict = (Pair<Integer, Integer>)v.getTag(); 
... 
filpsound = MediaPlayer.create(getApplicationContext(), pict.second) 

所以你不要需要复制粘贴代码相同的代码为每个ImageView的。

您可以同时持有字符串，公允价值这样创建一个内部类：私人

class Holder{ 
    int stringVal; 
    int soundVal; 

    public Holder(int stringVal,int soundVal) { 
     this.stringVal=stringVal; 
     this.soundVal=soundVal; 
    } 

} 

然后声明持有人的矢量如下：

Vector<Holder> stringsAndSounds=new Vector<Holder>(); 

然后做拷贝stringvalues和soundvalues stringsAndSounds arraylist如下：

for(int i=0;i<sltdalphabet.size() && i<sounds.size();i++){ 
    stringsAndSounds.add(new Holder(sltdalphabet.get(i), sounds.get(i))); 
} 

然后洗牌串AndSounds列表：

Collections.shuffle(stringsAndSounds); 

现在，你可以在任何地方访问stringsAndSounds在for循环如下，这已经是洗牌：

for(int i=0;i<stringsAndSounds.size();i++){ 

int stringVal = stringsAndSounds.elementAt(0).stringVal; 

int soundVal = stringsAndSounds.elementAt(0).soundVal; 
// do your code 

}
