Android中SoundPool的使用
大家知道MediaPlayer占用的资源比较多，且不可以同时支持播放多个音频，所以我们有一种叫做SoundPool，比如我们常见的按键音或者是手机提示音，还比如我们在游戏的开发中会有大量的音效效果等，下边介绍一下她的用法：
步骤如下：
1.创建SoundPool对象
*SoundPool源码中的构造方法方法体
* @param maxStreams 最多可以容纳多少个音频
* @param streamType 指定的声音类型，通过AudioManager类提供的常量进行指定
* @param srcQuality 指定音频的质量，默认为0
* @return a SoundPool object, or null if creation failed
public SoundPool(int maxStreams, int streamType, int srcQuality)
2.加载所需要播放的音频：
* @param context the application context
* @param resId the resource ID
* @param priority the priority of the sound. Currently has no effect. Use
a value of 1 for future compatibility.
* @return a sound ID. This value can be used to play or unload the sound.
public int load(Context context, int resId, int priority);
3.播放音频
* Play a sound from a sound ID.
* @param soundID
通过load方法返回的音频
* @param leftVolume
左声道的音量
* @param rightVolume 右声道的音量
* @param priority
优先级，值越大，优先级越高
* @param loop
循环的次数：0为不循环，-1为循环
* @param rate
指定速率，正常位1，为地位0.5，最高位2
* @return non-zero streamID if successful, zero if failed
public final int play(int soundID, float leftVolume, float rightVolume,
int priority, int loop, float rate)；
4.案例如下：
（1）布局文件：
（2）MainActivity.java文件
package com.
import java.util.HashM
import android.app.A
import android.media.AudioM
import android.media.SoundP
import android.os.B
import android.view.KeyE
import android.view.V
import android.view.View.OnClickL
import android.widget.B
public class MainActivity extends Activity {
private SoundP
//声明一个SoundPool对象
//使用HashMap管理各种音频
private HashMap soundmap = new HashMap();
//创建一个HashMap对象
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button chimes = (Button) findViewById(R.id.button1);
//获取&风铃声&按钮
Button enter = (Button) findViewById(R.id.button2);
//获取&布谷鸟叫声&按钮
Button notify = (Button) findViewById(R.id.button3);
//获取&门铃声&按钮
Button ringout = (Button) findViewById(R.id.button4);
//获取&电话声&按钮
soundpool = new SoundPool(5,
AudioManager.STREAM_SYSTEM, 0); //创建一个SoundPool对象，该对象可以容纳5个音频流
//将要播放的音频流保存到HashMap对象中
soundmap.put(1, soundpool.load(this, R.raw.chimes, 1));
soundmap.put(2, soundpool.load(this, R.raw.enter, 1));
soundmap.put(3, soundpool.load(this, R.raw.notify, 1));
soundmap.put(4, soundpool.load(this, R.raw.ringout, 1));
soundmap.put(5, soundpool.load(this, R.raw.ding, 1));
//为各按钮添加单击事件监听器
chimes.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
soundpool.play(soundmap.get(1), 1, 1, 0, 0, 1); //播放指定的音频
enter.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
soundpool.play(soundmap.get(2), 1, 1, 0, 0, 1);//播放指定的音频
notify.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
soundpool.play(soundmap.get(3), 1, 1, 0, 0, 1);//播放指定的音频
ringout.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
soundpool.play(soundmap.get(4), 1, 1, 0, 0, 1);//播放指定的音频
soundpool.play(soundpool.load(MainActivity.this, R.raw.notify, 1), 1, 1, 0, 0, 1);
//重写键被按下的事件
public boolean onKeyDown(int keyCode, KeyEvent event) {
soundpool.play(soundmap.get(5), 1, 1, 0, 0, 1);
//播放按键音
另外在资源文件中的raw文件中有几个小的铃声，这里不再显示。

今天做一个小Demo用到了SoundPool，总结一下。
MediaPlayer缺点：不能重叠播放音乐，封装程度比较高，所以加载起来会比较慢。
SoundPool简介
提供了另一种播放音效的类。用来加载多个音效，短促音效和多个短促音效，可自行设置声音品质，音量，重复和优先级。在一定场合还是很好用的。
属于android.media包下，继承自Object。
public SoundPool(int maxStreams, int streamType, int srcQuality) {...} 参数一 maxStreams：支持多少个声音（也就是池的大小） 参数二 streamType：指定声音类型通过AudioManager获取对应的常量值。 参数三 srcQuality：采样率变换质量，没用到。默认是0，没查到资料。。
SoundPool pool = new SoundPool(3, AudioManager.STREAM_MUSIC, 0);
指定了该池最多指定三个音频，使用用于系统声音的音频流。于AudioManager参数有很多，可以戳---& AudioManager。
有四个构造方法：
public int load(String path, int priority) 从完整文件路径名载入
path：文件路径
priority：优先级，0的优先级最低 返回值：这个声音的ID，用于打开和关闭音乐。 public int load(AssetFileDescriptor afd, int priority)
从Asset对象载入 afd：一个assets文件中的描述器，可以获得assets下文件的信息； priority： 返回值： public int load(Context context, int resId, int priority) 从APK资源获取
context： resId：文件的ID（res文件夹里的文件才有id） priority： public int load(FileDescriptor fd, long offset, long length, int priority) 从FileDescriptor对象载入
fd：文件描述类的实例 offset：从声音文件开始的偏移量（从什么地方播放） length：声音长度 priority：
构造方法： public final int play(int soundID, float leftVolume, float rightVolume,int priority, int loop, float rate) 参数一 soundID：所播放的声音ID，是load方法返回的 参数二 leftVolume：左音量，值从（0.0-1.0） 参数三 rightVolume：右音量，值从（0.0-1.0） 参数四 priority：优先级，0的优先级最低。 参数五 loop：是否循环，0不循环，-1一直循环。 参数六 rate：播放速率，1为正常速率。范围从0.5-2。
如果需要播放多首：需要一个集合来存储音频的ID，就是上面load方法返回的int。 如果指定播放一首：就不用建集合了，假设音频位于
//获取资源
AssetFileDescriptor fd = getResources().openRawResourceFd(R.raw.music)
//加载音频
int soundID = pool.load(fd, 1);
//播放音频，soundID是上面的返回值
pool.play(soundID, 1, 1, 0, 0, 1);
这样完成了一首音频的播放。 最后一个问题：播放多首音频。
声明一个集合存放音频 HashMap soundMap = new HashMap();
soundMap.put(1, pool.load(this, R.raw.music1, 1));
soundMap.put(2, pool.load(this, R.raw.music2, 1));
soundMap.put(3, pool.load(this, R.raw.music3, 1));
存放三个音频； pool.play(soundMap.get(1), 1, 1, 0, 0, 1);
pool.play(soundMap.get(2), 1, 1, 0, 0, 1);
pool.play(soundMap.get(3), 1, 1, 0, 0, 1);
这样就完成多首音频的播放
释放资源及其他
release()方法释放所有SoundPool对象占据的内存和资源。
pause(soundID)暂停播放
stop(soundID)停止播放
