如何使音池静音？

Question

我想允许用户使用按钮将应用静音，有人建议我“'stick a boolean on your MediaPlayerPool that you set to false when the mute button is pressed. Then in your playSound method, do nothing if the value is false.'”，但我不知道该怎么做。有人可以 post 示例代码吗？池代码：

public class MediaPlayerPool {

    private static MediaPlayerPool instance = null;
    private Context context;
    private List<MediaPlayer> pool;

    public static MediaPlayerPool getInstance(Context context) {
        if(instance == null) {
            instance = new MediaPlayerPool(context);
        }
        return instance;
    }

    private MediaPlayerPool(Context context) {
        this.context = context;
        pool = new ArrayList<>();
    }

    public void playSound(int soundId) {
        MediaPlayer mediaPlayer = MediaPlayer.create(context, soundId);

        mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
            @Override
            public void onCompletion(MediaPlayer mediaPlayer) {
                mediaPlayer.release();

                pool.remove(mediaPlayer);
                mediaPlayer = null;

            }
        });

        pool.add(mediaPlayer);
        mediaPlayer.start();
    }

}

为您的 MediaPlayerPool 添加一个变量 class，我们称它为 mute

public boolean mute = false;

有一个 mute/unmute 按钮及其 onClick 方法（将切换）：

MediaPlayerPool.getInstance().mute = !MediaPlayerPool.getInstance().mute

并且您的 playSound 方法变为

public void playSound(int soundId) {
    if(!mute) {
        // stick your current code here
    }
}
