从原始文件夹播放随机声音

Question

我目前有一个SoundPool加载并在屏幕抖动时播放单个声音，如何在每次屏幕抖动时播放不同的声音？

编辑---

private SensorManager mSensorManager; 
private ShakeEventListener mSensorListener; 
SoundPool sp; 
int soundOne; 
int soundTwo; 
int soundThree; 

protected void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.test); 
    //Shake sound 
    sp = new SoundPool(5, AudioManager.STREAM_MUSIC, 0); 
    soundOne = sp.load(this, R.raw.one, 1); 
    soundTwo = sp.load(this, R.raw.two, 1); 
    soundThree = sp.load(this, R.raw.three, 1);  

    //Shake 
    mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE); 
    mSensorListener = new ShakeEventListener(); 
    mSensorListener.setOnShakeListener(new ShakeEventListener.OnShakeListener() { 

     public void onShake() { 
      if (acceptCheck == 1) 
      { 
       sp.play(soundOne, 1, 1, 0, 0, 1); 
      } 
     } 
     }); 




}

只需使用整数，而不是将它们存储所有单独的列表：

private SensorManager mSensorManager; 
private ShakeEventListener mSensorListener; 
SoundPool sp; 
List<Integer> mSounds = new ArrayList<Integer>(); 
private Random mRandom = new Random(); 

protected void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.test); 
    //Shake sound 
    sp = new SoundPool(5, AudioManager.STREAM_MUSIC, 0); 
    mSounds.add(sp.load(this, R.raw.one, 1)); 
    mSounds.add(sp.load(this, R.raw.two, 1)); 
    mSounds.add(sp.load(this, R.raw.three, 1);  

    //Shake 
    mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE); 
    mSensorListener = new ShakeEventListener(); 
    mSensorListener.setOnShakeListener(new ShakeEventListener.OnShakeListener() { 

     public void onShake() { 
      if (acceptCheck == 1) 
      { 
       sp.play(mSounds.get(mRandom.nextInt(mSounds.size())), 1, 1, 0, 0, 1); 
      } 
     } 
     }); 
}

首先，你可以创建你所有的原材料的引用数组：

private int[] rawRef = {R.raw.1,R.raw.2,R.raw.3,R.raw.4,R.raw.5}; 

然后，你需要一种方法来播放音频：

 
private Random random = new Random(); 

private void play() { 
    MediaPlayer mp; 
    try { 
     mp = MediaPlayer.create(this, rawRef[random.nextInt(rawRef.length)]); 
     mp.start(); 
    } catch (Exception e) { 
     Log.e("ERROR", "Media Player", e); 
     mp = null; 
    } 
} 

For SoundPool

 
    private List pool = new ArrayList(); 
    private SoundPool sp; 

    private void loadSounds(){ 
     sp = new SoundPool(5, AudioManager.STREAM_MUSIC, 0); 
     pool.add(sp.load(context, R.raw.1, 1)); 
     pool.add(sp.load(context, R.raw.2, 1)); 
     pool.add(sp.load(context, R.raw.3, 1)); 
     pool.add(sp.load(context, R.raw.4, 1)); 
    } 

    private void play(){ 
     sp.play(pool.get(random.nextInt(pool.size()), 1, 1, 0, 0, 1); 
    }
