Android音板不会播放声音

我创建了一个音板，每次我点击一个按钮播放某种声音都不会发生。这里是声音管理器代码：Android音板不会播放声音

package com.androidbook.ufgsoundboard; 

import java.util.HashMap; 

import android.app.Activity; 
import android.content.Context; 
import android.media.AudioManager; 
import android.media.SoundPool; 



public class SoundManager extends Activity { 

    private SoundPool mSoundPool; 
    private HashMap<Integer, Integer> mSoundPoolMap; 
    private AudioManager mAudioManager; 
    private Context mContext; 


    public SoundManager() 
    { 

    } 

    public void initSounds(Context theContext) { 
     mContext = theContext; 
     mSoundPool = new SoundPool(4, AudioManager.STREAM_MUSIC, 0); 
     mSoundPoolMap = new HashMap<Integer, Integer>(); 
     mAudioManager = (AudioManager)mContext.getSystemService(Context.AUDIO_SERVICE);   
    } 

    public void addSound(int Index,int SoundID) 
    { 
     mSoundPoolMap.put(Index, mSoundPool.load(mContext, SoundID, 1)); 

    } 

    public void playSound(int index) { 

     int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC); 
     mSoundPool.play(mSoundPoolMap.get(index), streamVolume, streamVolume, 1, 0, 1f); 
    } 

}

这里是音板代码：

       SoundButton16.setOnClickListener(new OnClickListener() { 

      public void onClick(View v) { 
       mSoundManager.playSound(23); 

      } 
     });  
       Button SoundButton17 = (Button)findViewById(R.id.button19); 
       SoundButton17.setOnClickListener(new OnClickListener() { 

      public void onClick(View v) { 
       mSoundManager.playSound(22); 

      } 
     });  
       Button SoundButton18 = (Button)findViewById(R.id.button20); 
       SoundButton18.setOnClickListener(new OnClickListener() { 

      public void onClick(View v) { 
       mSoundManager.playSound(24); 

      } 

       }); 
     }};

我不能工作了，为什么它不会加载。按下按钮时突出显示，但没有声音。我错过了明显的东西吗？

您是否收到任何日志消息？ – nhaarman

Niek - 哪里可以找到日志消息？ logcat除了几个更新错误之外什么都没有真正出现，但是当我单击按钮时它们不会出现。 – Paul

为什么SoundManager类扩展Activity？它看起来更像一个包装类，不应该这样做，从我可以告诉。 –

你的代码是如此复杂，使用此相反，它为我工作！这是播放声音的单个按钮的示例

package com.example.soundtest; 

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

public class MainActivity extends Activity { 
/** Called when the activity is first created. */ 

Button white; 
SoundPool spool; 
int soundID; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    this.setVolumeControlStream(AudioManager.STREAM_MUSIC); 
    spool = new SoundPool(1, AudioManager.STREAM_MUSIC, 0); 
    soundID = spool.load(this, R.raw.anysoundfile, 1); 

    white = (Button)findViewById(R.id.button1); 
    white.setOnClickListener(new View.OnClickListener() { 
     public void onClick(View v) { 
      Sound(); 
     } 
    }); 
} 

public void Sound(){ 
    AudioManager audioManager = (AudioManager) getSystemService(AUDIO_SERVICE); 
    float volume = (float) audioManager.getStreamVolume(AudioManager.STREAM_MUSIC); 
    spool.play(soundID, volume, volume, 1, 0, 1f); 

}; 
}
