Description

一种音量调节方法、智能电视及存储介质 技术领域
所述PCT专利申请要求申请日为2019年03月11日，申请号为201910179450.4的中国专利优先权，本专利申请结合了上述专利的技术方案。本公开涉及音量调节技术领域，尤其涉及一种音量调节方法、智能电视及存储介质。
背景技术
现有Android智能电视设备一般是通过遥控器来调节电视的音量，在使用遥控器调节音量时每次按键可以将音量增大或减小一级，长按按键调节(大幅度调节音量)则是每次重复调节一级。由于电视机上的音量级数通常较多(通常都是100级)，所以当用户希望调节的音量值跨度比较大时，这个过程的耗时就会比较长，某些场合下这个耗时过长的操作会给用户的使用带来不便。
也就是说，往往用户在长按音量键调节操作时是希望做快速的大幅度调节的，然而现有电视设备上对长按按键时的音量调节操作未作特别的处理，用户的操作耗时是随需要调节的音量值跨度线性增加的，所以现有技术在做此类操作时存在耗时过长，用户调节不方便的问题。
因此，现有技术还有待于改进和发展。
发明内容
本公开的主要目的在于提供一种音量调节方法、智能电视及存储介质，旨在解决现有的电视声音调整时无法快速调节声音、用户操作时间长、不方便的问题。

可选地，当直接调解音量事件时根据用当前的重复次数选择不同的音量调节步长，重复次数越大，音量调节步长越大。

具体实施方式
为使本公开的目的、技术方案及优点更加清楚、明确，以下参照附图并举实施例对本公开进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本公开，并不用于限定本公开。
本公开较佳实施例所述的音量调节方法，如图1所示，所述音量调节方法包 括以下步骤：
步骤S10、接收音量键长按事件后，开始对重复次数进行计数。
具体的过程请参阅图2，其为本公开提供的音量调节方法中步骤S10的流程图。
如图2所示，所述步骤S10包括：
S11、调用系统服务接收音量键长按事件；
S12、接收音量键长按事件后，开启计数器对重复次数进行计数；
S13、根据所述重复次数得到按键时长，且所述按键时长与所述重复次数呈线性关系。
具体地，在所述步骤S10之前还包括:预先设置不同重复次数对应不同音量调节步长的关系,例如重复次数5次对应音量调节步长为5级、重复次数10次对应音量调节步长为10级等，此处不进行限定，预先设置对应关系即可。
例如，由Android Phone Window Manager Service中收到音量键长按事件时，开始做repeat Count(重复次数)的计数，repeat Count的数字越大，说明按键的时间越长。
其中，Window Manager Service(简称WMS)是Android Framework (Framework即架构，它是一个语言开发软件，提供了软件开发的框架，使开发更具工程性、简便性和稳定性)中一个重要的系统服务，用来管理系统中窗口(Window)的行为。Window是一个抽象的概念，它是一个矩形区域，用来绘制UI界面，响应用户的输入事件。Android系统的界面，从Framework层的角度来看，就是由一个一个窗口组合而成的。
也就是说，本公开在Android TV上利用Framework层音量键长按按键操作时的repeat Count计数，对长按音量键的音量调节操作进行了分段逻辑优化，实现对音量调节速度的非线性加速效果。
步骤S20、当所述重复次数大于预设值时，根据所述重复次数选择对应的音量调节步长。
具体的过程请参阅图3，其为本公开提供的音量调节方法中步骤S20的流程图。
如图3所示，所述步骤S20包括：
S21、预先设置一用于判断是否需要加速调节音量的预设值；
S22、当判断出所述重复次数大于所述预设值时，调取预先设置的不同重复次数对应不同音量调节步长的关系信息；
S23、根据当前重复次数，在对应关系中选择当前重复次数对应的音量调节步长。
例如，每次dispatch Direct Audio Event(直接调解音量事件)时利用当前的repeat Count选择不同的音量调节步长，repeat Count越大，音量调节步长也越大，也就更加能缩短音量的调节时间。
另外，当所述重复次数小于等于预设值(即repeat Count小于10次)时，相当于长按按键的初始阶段，则控制音量调节步长维持初始值不变，以保证用户的精准操作不受影响。
步骤S30、根据所述音量具体地，需要预先设置一用于判断是否需要加速调节音量的预设值，所述预设值优先为10次，因为电视机上的音量级数通常都是100级，选取级数较低的10次作为预设值较为合理，当然也可以是其他的值。
调节步长修改设置音量，并控制界面上音量条的显示和刷新。
具体过程请参阅图4，其为本公开提供的音量调节方法中步骤S30的流程图。
如图4所示，所述步骤S30包括：
S31、根据所述音量调节步长非线性加速调节音量，并根据按键时长的增加逐步增大音量调节步长；
S32、在音量调节的过程中，在显示界面上显示当前变化的音量条并在音量变化后实时进行刷新。
其中，所述非线性加速调节音量包括调大音量和调小音量，也就是说，无论是长按按键(遥控器上音量调节按键)调大音量还是调小音量都可以通过这种方式来实现，也就是不管是调大音量还是调小音量都可以通过选择合适的音量调节步长来缩短音量调节时间。
例如，通过dispatch Direct Audio Event依据repeat Count在不同阶段使用不同的adjust Step(调整步骤)调用Audio Service(音频服务)中的set Stream Volume(设置音量)方法修改设置音量，同时Audio Service通知System UI(系统用户界面)进行音量条的显示和刷新。
进一步地，在音量调节过程中判断音量调节是否越界，当大于最大音量值时，则直接将音量设置为最大音量值；当小于最小音量值时，则直接将音量设置为最小音量值。例如，音量调节过程中需要判断是否会越界，当oldIndex+adjustStep(调节后的音量)大于最大音量值100(假设最大音量值为100)时，直接设置为100，反之当oldIndex+adjustStep(调节后的音量)小于最小音量值0(假设最小音量值为0)时，直接设置为0。
本公开实现了长按音量键调节音量时的非线性加速效果，按键时间短时维持原有的音量调节逻辑，随着按键时间的增加逐步增大音量调节的步长，从而实现缩短操作时间，改善用户操作的效果。
例如，如图5所示，假设遥控器按键的repeat(重复)间隙时为100ms，则不使用本音量调节加速方法的情况下将音量从0调节到100需要10s；反之使用本公开的音量加速后，音量会按照图5中的曲线增大，从0到100只需要4s即可完成，大幅缩减了操作耗时，使得用户可以快速调节音量。
本公开通过在Android TV上利用Framework层音量键长按按键操作时的repeat Count计数，对长按音量键的音量调节操作进行了分段逻辑优化，实现对音量调节速度的非线性加速效果，从而在不影响用户操作精准性的同时达到优化操作时间，提高了用户体验的效果。
进一步地，如图6所示，基于上述音量调节方法，本公开还相应提供了一种智能电视，所述智能电视包括处理器10、存储器20及显示器30。图6仅示出了智能电视的部分组件，但是应理解的是，并不要求实施所有示出的组件，可以替代的实施更多或者更少的组件。
所述存储器20在一些实施例中可以是所述智能电视的内部存储单元，例如智能电视的硬盘或内存。所述存储器20在另一些实施例中也可以是所述智能电视的外部存储设备，例如所述智能电视上配备的插接式硬盘，智能存储卡(Smart Media Card,SMC)，安全数字(Secure Digital,SD)卡，闪存卡(Flash Card)等。进一步地，所述存储器20还可以既包括所述智能电视的内部存储单元也包括外部存储设备。所述存储器20用于存储安装于所述智能电视的应用软件及各类数据，例如所述安装智能电视的程序代码等。所述存储器20还可以用于暂时地存储已经输出或者将要输出的数据。在一实施例中，存储器20上存储有音量调节 程序40，该音量调节程序40可被处理器10所执行，从而实现本申请中音量调节方法。

所述当所述重复次数大于预设值时，根据所述重复次数选择对应的音量调节步长包括：
预先设置一用于判断是否需要加速调节音量的预设值；
当判断出所述重复次数大于所述预设值时，调取预先设置的不同重复次数对应不同音量调节步长的关系信息；
根据当前重复次数，在对应关系中选择当前重复次数对应的音量调节步长。
当直接调解音量事件时根据用当前的重复次数选择不同的音量调节步长，重复次数越大，音量调节步长越大。
所述根据所述音量调节步长修改设置音量，并控制界面上音量条的显示和刷新包括：
根据所述音量调节步长非线性加速调节音量，并根据按键时长的增加逐步增大音量调节步长；
在音量调节的过程中，在显示界面上显示当前变化的音量条并在音量变化后实时进行刷新；
所述非线性加速调节音量包括调大音量和调小音量。
通过直接调解音量事件依据重复次数在不同阶段使用不同的调整步骤调用音频服务中的设置音量方法修改设置音量，同时音频服务通知系统用户界面进行音量条的显示和刷新。
所述音量调节方法还包括：
在音量调节过程中判断音量调节是否越界，当大于最大音量值时，则直接将音量设置为最大音量值；当小于最小音量值时，则直接将音量设置为最小音量值。
其中，所述预设值为10次。
本公开还提供一种存储介质，其中，所述存储介质存储有音量调节程序，所述音量调节程序被处理器执行时实现如上所述的音量调节方法的步骤。
综上所述，本公开提供一种音量调节方法、智能电视及存储介质，所述方法包括：接收音量键长按事件后，开始对重复次数进行计数；当所述重复次数大于预设值时，根据所述重复次数选择对应的音量调节步长；根据所述音量调节步长修改设置音量，并控制界面上音量条的显示和刷新。本公开在通过按键长按来调节音量事，选择合适的音量调节步长来加速调节音量，实现了对音量调节速度的非线性加速效果，从而在不影响用户操作精准性的同时缩短音量调节的操作时间，方便用户对音量的快速调节。
当然，本领域普通技术人员可以理解实现上述实施例方法中的全部或部分流 程，是可以通过计算机程序来指令相关硬件(如处理器，控制器等)来完成，所述的程序可存储于一计算机可读取的存储介质中，所述程序在执行时可包括如上述各方法实施例的流程。其中所述的存储介质可为存储器、磁碟、光盘等。
应当理解的是，本公开的应用不限于上述的举例，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，所有这些改进和变换都应属于本公开所附权利要求的保护范围。
