主要还是希望开箱即用。所以才有了这篇，也是备忘。

以下代码适合Android5.0版本以后

        private SoundPool soundPool;//特效播放private Map<String,Integer> soundPoolMap;//       Builder builder=new SoundPool.Builder();builder.setMaxStreams(4);///最大4个声音流，播放超出时会根据优先级挤掉其他声音流。AudioAttributes.Builder audiobuilder=new AudioAttributes.Builder();//设置属性，唯一注意就是不能设置为null，不设置也可以，将使用默认设置。audiobuilder.setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION);audiobuilder.setUsage(AudioAttributes.USAGE_MEDIA);AudioAttributes attributes=  audiobuilder.build();builder.setAudioAttributes(attributes);soundPool = builder.build();//存放载入好的声音资源IDsoundPoolMap = new HashMap<String,Integer>();   
//	    soundPoolMap = new SparseIntArray();   final String bgm="bgm";final String sound1="sound1";soundPoolMap.put(bgm, soundPool.load(this, R.raw.sound1, 1));Log.i(TAG,"soundPoolMap.load bgm");//soundPoolMap.put(sound1, soundPool.load(this, R.raw.sound2, 1));Log.i(TAG,"soundPoolMap.load sound1");home = (ImageButton) findViewById(R.id.home);menu = (ImageButton) findViewById(R.id.menu);/*** 这里必须要等资源加载完毕之后才能播放，不然会报错播放失败*/soundPool.setOnLoadCompleteListener(new SoundPool.OnLoadCompleteListener() {@Overridepublic void onLoadComplete(SoundPool soundPool, int sampleId, int status) {playSound(bgm, -1);//0:no-loop,-1:loop-forever}});menu.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {playSound(sound1, 0);//0:no-loop,-1:loop-forever}});public void playSound(String soundName,int loop){AudioManager mgr = (AudioManager)this.getSystemService(Context.AUDIO_SERVICE);   float streamVolumeCurrent = mgr.getStreamVolume(AudioManager.STREAM_MUSIC);   float streamVolumeMax = mgr.getStreamMaxVolume(AudioManager.STREAM_MUSIC);       float volume = streamVolumeCurrent / streamVolumeMax;Log.i(TAG, "streamVolumeCurrent:"+streamVolumeCurrent+" streamVolumeMax:"+streamVolumeMax);int sound_id=soundPoolMap.get(soundName);Log.i(TAG, " soundPool.play:sound_id:"+sound_id);if(0==soundPool.play(sound_id, volume, volume, 0, loop, 1f)){Log.e(TAG, "music play failed!");}}

也没啥需要注意的，就是在记得一定要等资源加载好以后再播放。里面使用了OnLoadCompleteListener来处理。

资源如下：
