是否有一个监听器来监听android中的音量变化？

AudioManager audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);

OnAudioFocusChangeListener audioFocusChangeListener = new OnAudioFocusChangeListener() {
    @Override
    public void onAudioFocusChange(int focusChange) {
        // 处理音量变化事件
        switch (focusChange) {
            case AudioManager.AUDIOFOCUS_GAIN:
                // 音量增加
                break;
            case AudioManager.AUDIOFOCUS_LOSS:
                // 音量丢失
                break;
            case AudioManager.AUDIOFOCUS_LOSS_TRANSIENT:
                // 音量临时丢失
                break;
            case AudioManager.AUDIOFOCUS_LOSS_TRANSIENT_CAN_DUCK:
                // 音量临时降低
                break;
        }
    }
};

int volumeType = AudioManager.STREAM_MUSIC; // 监听音乐流的音量变化
int flags = AudioManager.FLAG_SHOW_UI; // 显示音量变化的UI
audioManager.requestAudioFocus(audioFocusChangeListener, volumeType, flags);
