android-code-调整音量

这是不弹出界面的方式：

/**
   * @param value
   *            0 - 15
   */
  public void dealCMDSound(int value) {

    AudioManager mAudioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
    if (value >= 0
        && value <= mAudioManager
            .getStreamMaxVolume(AudioManager.STREAM_MUSIC)) {

      System.out.println("--- sound: " + value);

      mAudioManager.setStreamVolume(AudioManager.STREAM_MUSIC, value, 0);

      return;
    } else {
      Log.e(TAG, "--- illegal sound value: " + value + ",ignored! ---");
    }

  }
