Question

再次提出这个问题的道歉。我以为我找到了我想要的信息，但是公共无效停止（）似乎没有用。我正在使用Soundpool和SoundManger。我想在任何时候只播放一首声音。一旦按下另一个按钮，我希望所有先前的声音停止，并且只播放最近按下的按钮。

这是我的SoundManger：

package com.androidbook.ufgsoundboard;

import java.util.HashMap;

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



public class SoundManager {

    private  SoundPool mSoundPool; 
    private  HashMap<Integer, Integer> mSoundPoolMap; 
    private  AudioManager  mAudioManager;
    private  Context mContext;
    public static final int maxSounds = 1;

    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); 
    }


}

这是我的音板：

        setContentView(R.layout.petera);

        mSoundManager = new SoundManager();
        mSoundManager.initSounds(getBaseContext());
        mSoundManager.addSound(1, R.raw.sound1);

                startActivityForResult(myIntent, 0);

            } 


        });}

        };

我希望这是一个简单的改变，我似乎无法找到或解决这个问题。

感谢所有人的期待。

Answer 1

对于简单的应用程序，我使用此静态声音类。

public class Sound
{
private static MediaPlayer mp = null;

/** Stop old sound and start new one */
public static void play(Context context, int resource)
{
    stop(context);

    mp = MediaPlayer.create(context, resource);
    mp.setLooping(false);
    mp.start();
}

/** Stop the music */
public static void stop(Context context)
{
    if (mp != null)
    {
        mp.stop();
        mp.release();
        mp = null;
    }
}
}

Answer 2

在initSounds()的{{1}}方法中，将4更改为1：

SoundManager

我曾遇到过同样的问题：）
