Android-简单音频池

//下面为写的是一个类似于斗地主之类的抢地主之类的话语同时放出的效果，效果如下图所示，每个音效可以同时播放

代码如下 activity
import android.media.AudioManager;
import android.media.SoundPool;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
public class MainActivity extends AppCompatActivity {
    private SoundPool soundPool;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_palyallmusic);
       //设置音频的播放量
        soundPool = new SoundPool(3, AudioManager.STREAM_MUSIC,0);
        //给音频池设置加载完的监听
        soundPool.setOnLoadCompleteListener(new SoundPool.OnLoadCompleteListener() {
            @Override
            public void onLoadComplete(SoundPool soundPool, int sampleId, int status) {
               soundPool.play(sampleId,1,1,1,-1,1);
            }
        });
        public void music1(View view){soundPool.load(this,R.raw.chimp,1);}
        public void music2(View view){soundPool.load(this,R.raw.crickets,1);}
        public void music3(View view){soundPool.load(this,R.raw.dogbark,1); }
        public void music4(View view){soundPool.load(this,R.raw.roar,1); }
        public void music5(View view){soundPool.load(this,R.raw.rooster,1);}

     //退出程序时关闭音乐
        @Override
        protected void onDestroy() {
        super.onDestroy();
        if (soundPool==null){
            soundPool.release();
            soundPool=null;
          }
      }
      }
