如何使随机声音时，点击链接？

问题描述

所以，我在这里有4个声，我是用的Soundpool

So i have 4 sound here, i was use SoundPool

     sound1 = soundPool.load(this, R.raw.aww, 1);
     sound2 = soundPool.load(this, R.raw.arh, 1);
     sound3 = soundPool.load(this, R.raw.agg, 1);
     sound4 = soundPool.load(this, R.raw.uhh, 1);

所以我不知道如何使按钮选择随机声：

so i wonder how to make button choose random sound :

    click= (Button)findViewById(R.id.bm);
    click.setOnClickListener(new View.OnClickListener() {

          public void onClick(View click){
             //choose one of four sound to play
            }
        });
}

任何人有一些想法？

Anyone have some Idea?

推荐答案

您可以存储soundIDs在一个阵列和Random类的Java选择其中一个随机。

You can store soundIDs in an array and select one of them randomly with Random class of Java.

int[] sound = new int[4];
sound[0] = soundPool.load(this, R.raw.aww, 1);
sound[1] = soundPool.load(this, R.raw.arh, 1);
sound[2] = soundPool.load(this, R.raw.agg, 1);
sound[3] = soundPool.load(this, R.raw.uhh, 1);

Random random = new Random();

click = (Button) findViewById(R.id.bm);
click.setOnClickListener(new View.OnClickListener() {
    public void onClick(View click) {
        //choose one of four sound to play
        soundPool.play(sound[random.nextInt(4)], 1.0f, 1.0f, 0, 0, 1.0f);
    }
});
