播放拍照声音

1、使用MediaPlayer播放

/**
	 * 播放拍照声音
	 */
	private void playShutterSound()  
	{  
	    AudioManager am = (AudioManager)TakePicActivity.this.getSystemService(Context.AUDIO_SERVICE);  
	    int volume = am.getStreamVolume(AudioManager.STREAM_NOTIFICATION);  
	  
	    if (volume != 0)  
	    {  
	        MediaPlayer mp = MediaPlayer.create(TakePicActivity.this, Uri.parse("file:///system/media/audio/ui/camera_click.ogg"));  
	        if (mp != null) {
	        	mp.start();  
	        }
	    }  
	}  

2、使用SoundPool播放

rivate SoundPool mSoundPool = null;
	private final int MAX_SOUND_POOL = 2;	// 同时播放的音效个数
	private final int SOUND_POOL_ALERT = 0;
	private final int SOUND_POOL_TAKEPIC = 1;
	private final int SOUND_POOL_FILESAVE = 2;
	private boolean mSoundPoolLoadComplete = false;
	private HashMap<Integer, Integer> mSoundPoolMap;
	/**
	 * 
	 */
	private void initSoundPool() {
		// TODO Auto-generated method stub
		mSoundPool = new SoundPool(MAX_SOUND_POOL, AudioManager.STREAM_MUSIC, 0);
		mSoundPoolMap = new HashMap<Integer, Integer>();  
		mSoundPoolMap.put(SOUND_POOL_ALERT, mSoundPool.load(this, R.raw.mm, 1));  
		mSoundPoolMap.put(SOUND_POOL_TAKEPIC, mSoundPool.load(this, R.raw.takepic, 1)); 
		mSoundPoolMap.put(SOUND_POOL_FILESAVE, mSoundPool.load(this, R.raw.takepic, 1)); 
		
		mSoundPool.setOnLoadCompleteListener(new SoundPool.OnLoadCompleteListener() {
			@Override
			public void onLoadComplete(SoundPool arg0, int arg1, int arg2) {
				// TODO Auto-generated method stub
				handler.sendEmptyMessage(SOUND_POOL_LOAD_COMPLETE);
			}
		});
	}

Handler handler = new Handler() {
		public void handleMessage(Message msg) {
			switch (msg.what) {
						
			case SOUND_POOL_LOAD_COMPLETE:
				mSoundPoolLoadComplete = true;
				break;
				
			default:
				break;
			}
			super.handleMessage(msg);
		}
	};

if(mSoundPoolLoadComplete){
		mSoundPool.play(mSoundPoolMap.get(SOUND_POOL_ALERT), 1, 1, 0, 1, 1);//播放声音二次
	
mSoundPool.play(mSoundPoolMap.get(SOUND_POOL_ALERT), 1, 1, 0, 2, 1);//播放声音三次

}
