更改圖像隨機按鈕點擊，並觸發相應的監聽

Question

我有，我有5 ImageButtons的要求。我想隨機加載這些5 ImageButtons上的一些60 - 80圖像。我怎樣才能做到這一點？

public void setRandomImages(int n){ 
    Random rand = new Random(); 
    int x = rand.nextInt(5)+1; 

    switch (x) { 
    case 1: 
     bt1.setVisibility(View.VISIBLE); 
     bt1.setBackgroundColor(Color.RED); 
     bt1.setOnClickListener(new listener()); 

     bt2.setVisibility(View.VISIBLE); 
     bt2.setBackgroundColor(Color.BLACK); 
     bt2.setOnClickListener(new listener()); 

     bt3.setVisibility(View.VISIBLE); 
     bt3.setBackgroundColor(Color.BLUE); 
     bt3.setOnClickListener(new listener()); 

     bt4.setVisibility(View.VISIBLE); 
     bt4.setBackgroundColor(Color.GREEN); 
     bt4.setOnClickListener(new listener()); 

     bt5.setVisibility(View.VISIBLE); 
     bt5.setBackgroundColor(Color.YELLOW); 
     bt5.setOnClickListener(new listener()); 
     break; 

    default: 
     break; 
    } 

而且相應的加載圖像的onclick，我要玩一些聲音，對我可以使用處理程序。

所有我想知道的是如何引用相應的監聽器所選擇的圖片隨意。

即

如果我選擇一個圖像，我會播放聲音，然後裝入在它的位置不同的圖像，所有上述過程重複。

我知道這是所有的雜亂，但任何人誰理解我的要求，建議/幫助我。

我創建了一個非常基本的例子展示你如何隨機選擇圖像，這可以通過向對象添加屬性來擴展，就像你的情況一樣。

它只是一個快速的10分鐘原型的東西，點擊這裏。
