我有一个要求，我有 5 ImageButtons。我想在这 5 个上ImageButtons随机加载一些 60 - 80 个图像。我怎样才能做到这一点？
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;
}
同样onclick对于相应的加载图像，我想播放一些声音，因为我可以使用处理程序。
我想知道的是如何将相应的侦听器随机引用到选定的图像。
IE，
如果我选择一个图像，我将播放声音，然后在其位置加载不同的图像，并重复上述所有过程。
我知道这很混乱，但是任何了解我的要求的人都会建议/帮助我。
