Android一次播放1个声音

Question

很抱歉再次问这个问题。我以为我找到了我想要的信息，但 public void stop() 似乎不起作用。我正在使用 Soundpool 和 SoundManger。我只想一次只播放 1 个声音。一旦按下另一个按钮，我希望所有以前的声音停止并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：

        super.onCreate(savedInstanceState);
        setContentView(R.layout.petera);

        mSoundManager = new SoundManager();
        mSoundManager.initSounds(getBaseContext());
        mSoundManager.addSound(1, R.raw.sound1);
        mSoundManager.addSound(2, R.raw.sound2);

            } 


        });}

        };    

我希望这是一个我似乎无法找到或解决的简单更改。

谢谢大家的期待。

Answer 1

在 SoundManager 的 initSounds() 方法中，将 4 更改为 1：

mSoundPool = new SoundPool(1, AudioManager.STREAM_MUSIC, 0); 

我曾经遇到过同样的问题:)

祝你好运

Answer 2

对于简单的应用程序，我使用这个静态声音类。

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;
    }
}
}
