android中使用soundpool播放音频

package com.baorant.soundpooltest;

import java.util.HashMap;

import android.app.Activity;
import android.media.AudioManager;
import android.media.SoundPool;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity implements OnClickListener {
    Button bomb, shot, arrow;
    SoundPool soundPool;
    HashMap<Integer, Integer> soundMap = new HashMap<Integer, Integer>();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        bomb = (Button) findViewById(R.id.bomb);
        shot = (Button) findViewById(R.id.shot);
        arrow = (Button) findViewById(R.id.arrow);
        /**
         * 
         * soundPool对象的构造和sdk版本有关
         *  if(Build.VERSION.SDK_INT>=21){
         * SoundPool.Builder builder = new SoundPool.Builder();
         * builder.setMaxStreams(2);//传入音频数量 //AudioAttributes是一个封装音频各种属性的方法
         * AudioAttributes.Builder attrBuilder = new AudioAttributes.Builder();
         * attrBuilder.setLegacyStreamType(AudioManager
         * .STREAM_MUSIC);//设置音频流的合适的属性
         * builder.setAudioAttributes(attrBuilder.build());//加载一个AudioAttributes
         * mPool = builder.build(); }else{ mPool = new
         * SoundPool(2,AudioManager.STREAM_MUSIC,0); }
         */
        soundPool = new SoundPool(2, AudioManager.STREAM_MUSIC, 0);
        soundMap.put(1, soundPool.load(this, R.raw.bomb, 1));
        soundMap.put(2, soundPool.load(this, R.raw.shot, 1));
        soundMap.put(3, soundPool.load(this, R.raw.arrow, 1));
        bomb.setOnClickListener(this);
        shot.setOnClickListener(this);
        arrow.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
        case R.id.bomb:
            soundPool.play(soundMap.get(1), 1, 1, 0, 0, 1);
        case R.id.shot:
            soundPool.play(soundMap.get(2), 1, 1, 0, 0, 1);
        case R.id.arrow:
            soundPool.play(soundMap.get(3), 1, 1, 0, 0, 1);
        }

    }

}

使用soundpool播放声音的步骤如下：

1、使用soundpool.builder的构造器创建sound.builder对象

2、调用soundpool的构造器创建soundpool对象，构造器方法和sdk版本有关，具体参照上面代码内容

3、调用soundpool对象的load（）方法加载声音。最好用haspmap来管理加载的声音

4、调用soundpool的play()方法来播放声音
