Java MediaPlayer赢得'；不要停止播放，即使已编程为

我制作了一个简单的类，它处理与声音相关的一切。具有添加、播放、停止、释放和释放全部功能。它的工作原理是，您必须添加一首歌曲，然后通过您添加的歌曲名称调用play。任何时候需要停止，只需调用stop函数并将歌曲名称作为参数传递，它就会停止。我的问题是，即使它通过

stop（）

，它也不会停止

声音等级：

public class Sound
{
    private Map<String, MediaPlayer> songs = new HashMap<String, MediaPlayer>();

    private MediaPlayer currentlyPlayingSong;

    public Sound() {}

    public void Add(int songId, String songName, Context context)
    {
        MediaPlayer song = MediaPlayer.create(context, songId);

        songs.put(songName, song);
    }

    public void Play(String name, boolean shouldLoop)
    {
        MediaPlayer songToPlay = songs.get(name);

        if ( songToPlay != currentlyPlayingSong && songToPlay != null) 
    {
        currentlyPlayingSong = songToPlay;

        currentlyPlayingSong.start();

        currentlyPlayingSong.setLooping(shouldLoop);
    }
    }

    public void Stop(String name)
    {
        MediaPlayer songToStop = songs.get(name);
        if (songToStop != null)
        {
            songToStop.setLooping(false);

            songToStop.stop();
        }
    }

    public void Release(String name)
    {
        songs.get(name).release();
    }

    public void ReleaseAll()
    {
       LinkedList<MediaPlayer> _songs;

        _songs = (LinkedList)songs.values();

        for (int i = 0; i < _songs.size(); i++)
        {
            _songs.get(i).release();
        }
    }
}

片段：

public class MainMenuFragment extends Fragment {

    private ImageButton soundImgBtn;

    private FragmentConfig fragmentConfig;

    public MainMenuFragment()
    {
        fragmentConfig = new FragmentConfig();
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState)
    {
        //region Initiators
        View  view = inflater.inflate(R.layout.fragment_main_menu, container, false);

        soundImgBtn = (ImageButton)view.findViewById(R.id.soundImgBtn);
        //endregion

        //region Listeners

        soundImgBtn.setOnClickListener(
                new View.OnClickListener()
                {
                    @Override
                    public void onClick(View v)
                    {
                        SoundImgBtnClick(v);
                    }
                }
        );
        //endregion

        //Changes audio img
        if (((Main)getActivity()).GetIsSoundOn())
            soundImgBtn.setImageResource(android.R.drawable.ic_lock_silent_mode_off);

        else
            soundImgBtn.setImageResource(android.R.drawable.ic_lock_silent_mode);

        // Inflate the layout for this fragment
        return view;
    }

    private void SoundImgBtnClick(View v)
    {
        //if sound is on and clicked, turn off
        if (((Main)getActivity()).GetIsSoundOn())
        {
            ((Main)getActivity()).SetIsSoundOn(false);

            ((Main)getActivity()).GetSoundObj().Stop("mainMenuSong");

            soundImgBtn.setImageResource(android.R.drawable.ic_lock_silent_mode);
        }

        else
        {
            ((Main)getActivity()).SetIsSoundOn(true);

            ((Main)getActivity()).GetSoundObj().Play("mainMenuSong", true);

            soundImgBtn.setImageResource(android.R.drawable.ic_lock_silent_mode_off);
        }
    }

}

我想做的是模拟一个静音按钮。单击后，所有声音都应静音

到目前为止，这几乎是我编写的全部代码

干杯。

请尝试使用songToStop.release（）

我怀疑您使用的是不同的MediaPlayer实例。您可以这样做，但必须在同一实例中停止歌曲。 关于Add（）中的代码：

在Stop（）中：

注意：

• 上面的代码告诉我，您正在为同一首歌曲使用不同的MediaPlayer实例。需要在更高的范围内声明对象

  歌曲

  ，以便您访问它并停止歌曲
• 需要在stop（）之后调用release（）方法以释放资源

让它停下来。我的班级必须能够处理一首歌在同一时间和许多外汇。这就是我想到的
声音：

public class Sound
{
    private static MediaPlayer currentlyPlayingSong,
    currentlyPlayingFX;

    public Sound() {}

    public void PlayFX(int fxId, Context context, boolean shouldLoop)
    {
        MediaPlayer fx = MediaPlayer.create(context, fxId);

        if (currentlyPlayingFX != fx)
        {
            StopFX();

            currentlyPlayingFX = fx;

            currentlyPlayingFX.start();

            currentlyPlayingFX.setLooping(shouldLoop);
        }
    }

    public void PlaySong(int songId, boolean shouldLoop, Context context)
    {
        MediaPlayer song = MediaPlayer.create(context, songId);

        if (currentlyPlayingSong != song)
        {
            StopSong();

            currentlyPlayingSong = song;

            currentlyPlayingSong.start();

            currentlyPlayingSong.setLooping(shouldLoop);
        }
    }

    public void StopFX()
    {
        if (currentlyPlayingFX != null)
        {
            currentlyPlayingFX.stop();

            currentlyPlayingFX.release();

            currentlyPlayingFX = null;
        }
    }

    public void StopSong()
    {
        if (currentlyPlayingSong != null)
        {
            currentlyPlayingSong.stop();

            currentlyPlayingSong.release();

            currentlyPlayingSong = null;
        }
    }
}

这是基于@原安卓的回答。将其保留在单个实例上

谢谢你的帮助
如果我想再次调用同一首歌，这难道不会给我一个例外吗？我需要制作一个静音按钮，这就是停止的目的。它在模仿哑巴。如果我释放，那么我将不得不创建另一个对象。我不明白，你说的静音是什么意思？您要停止歌曲还是将歌曲静音。如果你想“停止”这首歌，有一个.pause（）函数。我想停止这首歌和静音是一样的。我需要它在调用

Play

时从头开始。“暂停”将暂停，当再次播放时，我假设它将从暂停处继续播放。我希望音频完全停止，但我不想发布歌曲它必须是同一个实例？该死的。我认为通过将

song

添加到

songs

中，然后将

songs.get（name）

分配给一个局部变量，它将继承它的所有值。出于同样的原因，歌曲是全局性的，因为我需要在任何地方访问歌曲地图。正如您所看到的，我没有使用

isplay（）

，因为大多数时间在实际播放时返回false。可能是像@Original Android Suggestions这样的实例问题的原因。在片段上，我在需要的地方调用了

PlaySong

。

currentlyPlaying

变量是为了避免使用

isPlaying

。我已经习惯了不正确，我只是想不惜一切代价避免它lol

MediaPlayer song = MediaPlayer.create(context, songId);

MediaPlayer songToStop = songs.get(name)

public class Sound
{
    private static MediaPlayer currentlyPlayingSong,
    currentlyPlayingFX;

    public Sound() {}

    public void PlayFX(int fxId, Context context, boolean shouldLoop)
    {
        MediaPlayer fx = MediaPlayer.create(context, fxId);

        if (currentlyPlayingFX != fx)
        {
            StopFX();

            currentlyPlayingFX = fx;

            currentlyPlayingFX.start();

            currentlyPlayingFX.setLooping(shouldLoop);
        }
    }

    public void PlaySong(int songId, boolean shouldLoop, Context context)
    {
        MediaPlayer song = MediaPlayer.create(context, songId);

        if (currentlyPlayingSong != song)
        {
            StopSong();

            currentlyPlayingSong = song;

            currentlyPlayingSong.start();

            currentlyPlayingSong.setLooping(shouldLoop);
        }
    }

    public void StopFX()
    {
        if (currentlyPlayingFX != null)
        {
            currentlyPlayingFX.stop();

            currentlyPlayingFX.release();

            currentlyPlayingFX = null;
        }
    }

    public void StopSong()
    {
        if (currentlyPlayingSong != null)
        {
            currentlyPlayingSong.stop();

            currentlyPlayingSong.release();

            currentlyPlayingSong = null;
        }
    }
