SoundPool

一个声音播放的辅助类，从名字可以看出，它具有 “池”的能力，它先加载声音文件到内存，以支持多次播放声音文件。

特点

SoundPool适合 短小的 声音文件SoundPool适合播放 “需要多次播放的提示音”，比如在 一些常用的 请登录，请点击什么的相比mediaPlayer，耗用资源更少　支持 同时 播放多个声音　

 

使用方法

　　创建实例

mSoundPool = new SoundPool(1, AudioManager.STREAM_ALARM, 0); soundPoolMap = new HashMap<Integer, Integer>(); //这里我创建一个 hash 表，用于记录加载过的声音的ID，一般我们会定义一个常量作为检索该声音的KEY

　　加载声音文件

soundPoolMap.put(KEY_SOUND_A1, mSoundPool.load(this, R.raw.a1, 1)); soundPoolMap.put(KEY_SOUND_A2, mSoundPool.load(this, R.raw.a2, 1));//注意，这里 hash表里 记录

　　播放声音文件

mSoundPool.play(soundPoolMap.get(KEY_SOUND_A1), 1, 1, 0, 0, 1); //注意，这里从hash表里取出了具体的ID

　　注册一个监听器，在加载声音完毕的时候获得消息

mSoundPool.setOnLoadCompleteListener(new SoundPool.OnLoadCompleteListener() { @Override public void onLoadComplete(SoundPool soundPool, int sampleId, int status) { alert(" " + sampleId); } });
