音效播放：
资源文件： res/raw/filename
声音池类：SoundPool sp = new
SoundPool(同时最大播放个数，AudioManager.STREAM_MUSIC,0);
将加载里音频文件的SoundPool添加到一个HashMap中，提供给以后的调用
HashMap spMap = new
HashMap
Integer>();
spMap.put(1,sp.load(this, R.raw.filename1,1));
spMap.put(2,sp.load(this, R.raw.filename2,1));
音效播放函数：
public void playSounds(int sound, int number){
//实例化AudioManager对象，控制声音
AudioManager
am =
(AudioManager)this.getSystemService(this.AUDIO_SERVICE);
//最大音量
float
audioMaxVolumn =
am.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
//当前音量
float
audioCurrentVolumn =
am.getStreamVolume(AudioManager.STREAM_MUSIC);
float
volumnRatio = audioCurrentVolumn/audioMaxVolumn;
//播放
sp.play(spMap.get(sound),
//声音资源
volumnRatio, //左声道
volumnRatio, //右声道
1, //优先级，0最低
number, //循环次数，0是不循环，-1是永远循环
1); //回放速度，0.5-2.0之间。1为正常速度
}
音效暂停：
sp.pause(spMap.get(1));
