Description

一种主题切换方法以及主题切换装置
本申请要求于2019年9月2日提交中国专利局、申请号为201910825379.2、申请名称为“一种主题切换方法以及主题切换装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及终端技术领域，尤其涉及一种主题切换方法及主题切换装置。
背景技术
随着终端的普及，以及通信技术的不断发展，人们对终端的功能提出了更高的要求。多变的主题可以让终端呈现的元素更加丰富，也能提高终端的趣味性。
但是，当前终端在同一时间下只有一种主题生效。如果需要切换到其他主题，需要用户手动在主题界面中选择待切换的主题，然后在该终端加载完该待切换的主题之后，才能完成主题切换。采用现有主题切换方法进行主题切换，需要一段时间加载待切换的主题，这样会导致切换效率较低。
发明内容
本申请实施例提供一种主题切换方法及主题切换装置，有利于提高主题切换效率。
第一方面，本申请实施例提供了一种主题切换方法，该方法应用于终端设备，该方法包括：在检测到主题切换操作时，获取切换参数；并根据该切换参数确定待启用主题对象，该待启用主题对象处于已加载状态；将该待启用主题对象切换为终端设备的主题对象。
在该技术方案中，由于在将待启用主题对象切换为终端设备的主题对象之前，该待启用主题对象处于已加载状态，可以避免在将待启用主题对象切换为终端设备的主题对象之前需要花费时间去加载该待启用主题对象，从而有利于提高终端设备的主题切换效率。
在一种实现方式中，该终端设备中存储有多个主题对象，该多个主题对象中的每个主题对象包括类加载器和路径信息，该主题对象由该类加载器加载该路径信息指示的主题包得到；其中，每个主题包包括资源标识和资源取值，不同主题包中的资源标识相同且资源取值不同，不同主题对象包括的类加载器不同。
在该技术方案中，相较于现有技术中不同主题包中的资源标识不同且资源取值不同，在本申请实施例中，不同主题包中的资源标识相同且资源取值不同，这样可以避免根据主题对象的个数选择资源标识，有利于减少代码量，并有利于提高主题切换效率。另外，在安卓操作系统中，不能定义两个相同的资源标识，但是由于本申请实施例中的不同主题对象是通过不同的类加载器加载得到的。因此，即使不同主题包中的资源标识相同，也可以在终端设备中同时加载该不同主题包。这样使得终端设备中可以存在多个处于已加载状态的主题对象，这样可以避免终端设备在检测到主题切换操作时，需要花费一段时间加载待启用主题对象，并在加载完毕之后才能实现主题切换，从而有利于提高主题切换效率和用户体验。
在一种实现方式中，该终端设备包括折叠屏，该折叠屏包括第一屏幕和第二屏幕；前 述主题切换操作包括如下操作中的一种或多种：对该折叠屏的折叠操作；使该第一屏幕和该第二屏幕之间的折叠角度变化为第一预设角度的折叠操作；使该第一屏幕和该第二屏幕之间的折叠角度的变化量达到第二预设角度的折叠操作。
在该技术方案中，当主题切换操作为使该第一屏幕和该第二屏幕之间的折叠角度的变化量达到第二预设角度的折叠操作时，可以避免终端设备发生碰撞或因其他原因使折叠屏发生抖动时(此时用户并不希望切换终端设备的主题对象)，导致第一屏幕和第二屏幕之间的折叠角度发生变化，进而使终端设备的主题发生切换的情况，有利于避免误操作。
在一种实现方式中，该切换参数包括折叠操作的折叠角度；根据该切换参数确定待启用主题对象的具体实施方式可以为：根据折叠角度和主题对象之间的对应关系，将该折叠操作的折叠角度对应的主题对象作为待启用主题对象。
在一种实现方式中，该切换参数包括折叠操作的折叠角度和辅助信息，该辅助信息包括：时间信息、日期信息和天气信息中的一种或多种；根据该切换参数确定待启用主题对象的具体实施方式可以为：根据折叠角度和主题对象集合之间的对应关系，确定与该折叠操作的折叠角度对应的目标主题对象集合；并根据该辅助信息，从该目标主题对象集合中确定待启用主题对象。
在该技术方案中，根据辅助信息，从该目标主题对象集合中确定待启用主题对象，有利于提高终端的趣味性。
在一种实现方式中，该终端设备包括折叠屏，该折叠屏包括第一屏幕和第二屏幕；将前述待启用主题对象切换为该终端设备的主题对象的具体实施方式可以为：将前述待启用主题对象切换为前述主题切换操作所操作的屏幕的主题对象。
在该技术方案中，可以在用户仅翻转终端设备包括的多个屏幕中的部分屏幕时，仅切换被用户翻转的屏幕的主题对象。
在一种实现方式中，该终端设备包括折叠屏，该折叠屏包括第一屏幕和第二屏幕；前述待启用主题对象包括第一主题对象和第二主题对象，该第一主题对象和该第二主题对象之间存在关联关系；将前述待启用主题对象切换为该终端设备的主题对象的具体实施方式可以为：将该第一主题对象切换为该第一屏幕的主题对象，并将该第二主题对象切换为该第二屏幕的主题对象。
在该技术方案中，第一主题对象和第二主题对象之间存在关联关系时，将该第一主题对象切换为该第一屏幕的主题对象，并将该第二主题对象切换为该第二屏幕的主题对象，有利于增强终端设备的趣味性。
第二方面，本申请实施例提供了一种主题切换装置，该装置为终端设备或具有终端设备功能的装置(例如芯片)。该装置具有实现第一方面所提供的主题切换方法的功能。该功能可以通过硬件实现，也可以通过硬件执行相应的软件实现。该硬件或软件包括一个或多个与上述功能相对应的模块。
第三方面，本申请实施例提供一种计算机可读存储介质，用于储存为第二方面所述的主题切换装置所用的计算机程序指令，其包含用于执行上述第一方面所涉及的程序。
第四方面，本申请实施例提供一种主题切换装置，该装置为终端设备或具有终端设备功能的装置(例如芯片)。该装置包括存储器和处理器，存储器中存储有程序指令，处理 器通过总线与存储器连接，处理器调用存储器中存储的程序指令以使该装置执行第一方面所述的方法。
第五方面，本申请实施例提供一种计算机程序产品，该程序产品包括程序，所述程序被执行时实现上述第一方面所述的方法。

具体实施方式
为了更好的理解本申请实施例公开的一种主题切换方法，下面首先对本申请实施例适用的应用场景进行描述。
请参见图1a，为本申请实施例提供的一种终端设备100的主屏幕的示意图。如图1a所示， 终端设备100的主屏幕包括多个应用图标(如视频、文件、照相机、音乐、商店、图库、设置、应用、电话和短信)以及时间图标、通信信号图标、无线局域网(wireless local area networks，WLAN)(如无线保真(wireless fidelity，Wi-Fi)网络连接状态图标、电池图标等。
当用户翻转图1a所示的终端设备100时，该终端设备100可以检测到主题切换操作，并获取切换参数，进而根据该切换参数确定待启用主题对象，该待启用主题对象处于已加载状态，然后将该待启用主题对象切换为终端设备100的主题对象。
其中，终端通过设置主题对象可以同时设置该终端的背景颜色、待机图片、屏幕保护程序、铃声、操作界面、图标、文字和屏幕布局等内容，使用户可以更便捷地为终端实现个性化。其中，屏幕布局可以确定屏幕中显示的元素在该屏幕中的显示位置。终端设备100中可以存储有多个主题对象，该多个主题对象至少包括终端设备100在被翻转之前所采用的主题对象(如主题对象1)以及终端设备100在被翻转之后所采用的主题对象(即前述待启用主题对象)。
图1b是用户翻转图1a所示的终端设备100的场景示意图。本申请实施例以待启用主题对象为主题对象2为例进行介绍，并以终端设备100采用主题对象1时，该终端设备100的主屏幕的背景颜色为白色，终端设备100采用主题对象2时，该终端设备100的主屏幕的背景颜色为灰色为例进行介绍。如图2b可见，用户翻转图1a所示的终端设备100之前，终端设备100的主屏幕的背景颜色为白色，用户翻转图1a所示的终端设备100之后，终端设备100的主屏幕的背景颜色变为灰色。换言之，用户翻转图1a所示的终端设备100(即终端设备100检测到主题切换操作)，可以将主题对象2切换为终端设备100的主题对象，即终端设备100的主题对象由主题对象1变为主题对象2。
切换参数可以包括图1b中的翻转角度，终端设备100可以存储有翻转角度和主题对象之间的对应关系，并根据该对应关系，将图1b中的翻转角度对应的主题对象作为待启用主题对象。需要说明的是，待启用主题对象处于已加载状态，待启用主题对象处于已加载状态表示：待启用主题对象已加载到终端设备100的内存空间中。本申请实施例在将待启用主题对象切换为终端设备100的主题对象之前，该待启用主题对象处于已加载状态，可以避免在将待启用主题对象切换为终端设备100的主题对象之前需要花费时间去加载该待启用主题对象，从而有利于提高终端设备100的主题切换效率。
需要说明的是，上述主题切换操作包括用户翻转图1a所示的终端设备100仅用于举例，并不构成对本申请实施例的限定，在其他可行的实现方式中，只要是用于触发主题切换的操作均为本申请实施例中所述的主题切换操作。换言之，本申请实施例提出的主题切换方法适用于任何主题切换场景。
其中，终端设备100也可以称为终端(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等。终端设备可以是手机(mobile phone)、智能电视、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self-driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家 庭(smart home)中的无线终端等等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
可以理解的是，本申请实施例描述的网络架构是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。

下面结合附图对本申请提供的主题切换方法及主题切换装置进行详细地介绍。
请参见图2a，图2a是本申请实施例提供的一种主题切换方法的流程示意图，该主题切换方法的执行主体为终端设备，或者为终端设备中的芯片，以下以终端设备为主题切换方法的执行主体为例进行说明。如图2a所示，该方法可以包括但不限于如下步骤：
步骤S201：在检测到主题切换操作时，终端设备获取切换参数。
在本申请实施例中，终端设备可以实时、周期或不定期检测预设的主题切换操作，并在检测到该主题切换操作时获取切换参数。具体的，主题切换操作可以是针对终端设备中的预设切换按钮的触发操作(如点击、长按或滑动操作)，该预设切换按钮可以是终端设备的显示屏中的虚拟按钮，也可以是终端设备中的硬件按键，本申请实施例对此不做限定。在一种实现方式中，主题切换操作可以是对终端设备的翻转操作，对终端设备的翻转操作会使得终端设备的翻转角度发生变化。对终端设备的翻转操作可以指使终端设备围绕第一方向旋转，该第一方向可以包括与终端设备的竖向边框(如图1a中终端设备100的边框中的长度方向，图1a未示出)平行的方向、与终端设备的横向边框(如图1a中终端设备100的边框中的宽度方向，图1a未示出)平行的方向或与终端设备的屏幕垂直的方向中的任意一种。在一种实现方式中，终端设备可以默认设置主题切换操作，也可以由用户自定义或者更改设置的主题切换操作。
终端设备检测到主题切换操作时，表明需要切换终端设备的主题对象。需要说明的是，终端设备的主题对象可以包括终端设备的操作系统所采用的主题对象和/或终端设备当前运行的应用程序所采用的主题对象。需要说明的是，在本申请实施例中提及终端设备的主题对象时，具体可以指终端设备的操作系统的主题对象和/或终端设备当前运行的应用程序的主题对象。针对终端设备的操作系统所采用的主题对象的主题切换操作，和终端设备当前运行的应用程序所采用的主题对象的主题切换操作可以相同，换言之，终端设备在检测到主题切换操作时，表明需要切换终端设备的操作系统所采用的主题对象和终端设备当前运行的应用程序所采用的主题对象。其中，操作系统(operating system，OS)是管理计算机硬件和软件资源的系统软件，为计算机程序提供公共服务。本申请实施例中提及的操作系统可以为安卓操作系统或基于安卓二次开发的操作系统。
在一种实现方式中，针对终端设备的操作系统所采用的主题对象的主题切换操作，和终端设备当前运行的应用程序所采用的主题对象的主题切换操作可以完全不同或不完全相同。例如，假设检测到操作1、操作2和操作3中的任意一种操作表示需要切换终端设备的操作系统的主题对象，检测到操作3和操作4中的任意一种操作表示需要切换终端设备当前运行的应用程序的主题对象时。若终端设备检测到操作1或操作2，则终端设备可以 切换该终端设备的操作系统的主题对象；若终端设备检测到操作4，则终端设备可以切换该终端设备当前运行的应用程序的主题对象；若终端设备检测到操作3，则终端设备可以切换该终端设备的操作系统的主题对象，并切换该终端设备当前运行的应用程序的主题对象。其中，终端设备当前运行的应用程序的数量可以为一个或多个。
需要说明的是，终端设备当前运行应用程序1表示应用程序1在终端设备中处于运行状态，应用程序1在终端设备中处于运行状态可以包括如下3种状态中的任意一种：应用程序1在终端设备中处于前台运行状态；应用程序1在终端设备中处于待激活状态；应用程序1在终端设备中处于后台运行状态。其中，导致应用程序1在终端设备中处于待激活状态的情况可以包括但不限于：终端设备在应用程序1处于前台运行状态时，下拉状态栏看通知消息、双击起始键(也称home键)并弹出任务运行栏，锁屏。导致应用程序1在终端设备中处于后台运行状态的情况可以包括但不限于：终端设备在应用程序1处于前台运行状态时，按home键或启动其它应用(导致把应用程序1挤入后台)。
在一种实现方式中，终端设备中安装的所有应用程序对应的主题切换操作相同。在另一种实现方式中，终端设备中安装的各个应用程序对应的主题切换操作完全不同或者不完全相同。例如，若应用程序1和应用程序2在终端设备中均处于运行状态，且应用程序1对应的主题切换操作为操作1、操作2和操作3中的任意一种操作，应用程序2对应的主题切换操作为操作3。终端设备在检测到操作1和操作2中的任意一种操作时，表示需要切换应用程序1的主题对象；终端设备在检测到操作3时，表示需要切换应用程序1和应用程序2的主题对象。
终端设备通过设置操作系统的主题对象可以同时设置该终端设备的主屏幕的背景颜色、待机图片、屏幕保护程序、铃声、操作界面、图标、文字和屏幕布局等内容。终端设备通过设置应用程序的主题对象可以同时设置该应用程序的窗口的背景颜色、背景图片、消息铃声、操作界面、图标、文字和屏幕布局等内容。通过设置操作系统的主题对象或者应用程序的主题对象，使用户可以更便捷地为终端实现个性化。
在一种实现方式中，终端设备可以设置操作系统默认的主题对象，并设置各个应用程序默认的主题对象。在启动终端设备时，可以将操作系统默认的主题对象作为终端设备的操作系统的主题对象。相应的，在启动终端设备中安装的某应用程序时，可以将该应用程序默认的主题对象作为该应用程序的主题对象。
在本申请实施例中，终端设备处于开机状态时，该终端设备的操作系统已启用了主题对象，在检测到主题切换操作时，终端设备可以获取切换参数，并根据切换参数确定待启用主题对象，进而用该待启用主题对象替换检测到主题切换操作之前，操作系统所启用的主题对象。
需要说明的是，在本申请实施例中，提及的主题切换操作包括针对操作系统的主题切换操作和针对终端设备中运行的应用程序的主题切换操作，在检测到对操作系统的主题切换操作之后执行的一系列操作，与检测到对应用程序的主题切换操作之后执行的一系列操作类似。为避免描述冗余，在本申请实施例中部分内容仅描述检测到对操作系统的主题切换操作之后执行的一系列操作，据此可以推理得到检测到对应用程序的主题切换操作之后执行的一系列操作，并不构成对于本申请实施例提供的技术方案的限定。
步骤S202：终端设备根据该切换参数确定待启用主题对象，该待启用主题对象处于已加载状态。
在本申请实施例中，切换参数可以根据终端设备检测到的主题切换操作确定。例如，主题切换操作是针对终端设备中显示的主题设置页面中的确定设置按钮的触发操作时，切换参数可以是用户在主题设置页面中选择的主题参数。以图2b所示的用户在主题设置页面中设置主题参数的场景示意图为例，如图2b可见，主题设置页面20中可以对背景颜色和图标形状进行设置，即主题参数包括背景颜色和图标形状，背景颜色可以为白色或者灰色，图标形状可以为方形或者圆形。在检测到针对终端设备100中显示的主题设置页面中的确定设置按钮22的触发操作之前，该终端设备的主屏幕如图1a所示。由图2b也可以看到，在改变主题参数之前，该终端设备100的主屏幕的背景颜色为白色，图标形状为方形。由图2b可知，在主题设置页面20中，用户可以通过点击背景颜色对应的下拉框21，以使主题设置页面20显示背景颜色的所有选项(即白色和灰色)，并在显示的颜色选项中选择灰色。同理，在主题设置页面20中，用户可以通过点击图标形状对应的下拉框21，以使主题设置页面20显示图标形状的所有选项(即方形和圆形)，并在显示的形状选项中选择圆形。在完成背景颜色和图标形状的选择之后，用户可以点击确定设置按钮22，以使选择的主题参数生效。用户也可以点击取消设置按钮，以取消对主题参数的设置，这样选择的主题参数不会生效。用户点击主题设置页面中的确定设置按钮22之后，终端设备100的主屏幕的示意图如图2c所示。由图2c所示，终端设备100的主屏幕中的图标23的形状为圆形，背景颜色为灰色，即用户选择的主题参数生效。
需要说明的是，上述例子中，主题参数包括背景颜色和图标形状仅用于举例，并不构成对本申请实施例的限定，在其他可行的实现方式中，主题参数还可以包括其他参数。还需要说明的是，用户同时改变了背景颜色和图标形状仅用于举例，并不构成本申请实施例的限定，在其他可行的实现方式中，用户可以仅改变背景颜色和图标形状中的一个参数。
在一种实现方式中，切换参数根据终端设备检测到的主题切换操作确定，且主题切换操作是对终端设备的翻转操作时，切换参数可以是终端设备执行翻转操作之后该终端设备的翻转角度。以图1b为例，翻转角度可以是终端设备100的屏幕平面与地平面之间的夹角。在一种实现方式中，切换参数可以是终端设备执行翻转操作之前该终端设备的翻转角度，与执行翻转操作之后该终端设备的翻转角度之间的角度差。
在本申请实施例中，终端设备中可以存储有多个主题对象，该多个主题对象至少包括终端设备在检测到主题切换操作之前所采用的主题对象以及终端设备检测到主题切换操作之后所采用的主题对象。操作系统包括的主题参数与应用程序包括的主题参数可以相同也可以不同。例如，操作系统的主题参数可以包括主屏幕的背景颜色和图标形状，应用程序的主题参数也可以包括该应用程序的界面的背景颜色和该界面中的图标的形状，或者，应用程序的主题参数可以包括该应用程序的界面的背景颜色、该界面中的图标的形状和该界面的背景图像。不同应用程序包括的主题参数可以相同也可以不同。换言之，操作系统对应的主题对象与应用程序对应的主题对象可以相同也可以不同，不同应用程序对应的主题对象可以相同也可以不同。
在本申请实施例中，终端设备可以预先设置切换参数和主题对象之间的对应关系，并 将获取的主题参数对应的主题对象作为待启用主题对象。在一种实现方式中，切换参数和主题对象之间一一对应。
在一种实现方式中，终端设备中可以存储有多个主题对象，该多个主题对象中的每个主题对象可以包括类加载器和路径信息，该主题对象由该类加载器加载该路径信息指示的主题包得到；其中，每个主题包可以包括资源标识(资源ID)和资源取值，不同主题包中的资源ID相同且资源取值不同，不同主题对象包括的类加载器不同。
其中，类加载器可以用于将路径信息指示的主题包加载到终端设备的内存空间中，需要说明的是，类加载器将路径信息指示的主题包加载到终端设备的内存空间中之后，该终端设备可以得到一个主题对象。终端设备在检测到主题切换操作时，直接切换启用的主题对象，即可实现主题切换。具体的，该类加载器可以是Java类加载器，Java类加载器是Java运行时环境(java runtime environment)的一部分，负责动态加载Java类到Java虚拟机的内存空间中。路径信息用于唯一指示一个主题包在终端设备中的存储位置，不同路径信息指示的主题包不同。其中，当终端设备的操作系统为安卓时，主题包可以为安卓应用程序包(android application package，APK)；当终端设备的操作系统为其他操作系统时候，主题包可以为该操作系统中的应用程序包。
主题包包括构成一个主题所需要的所有资源，具体的，主题包可以包括资源ID和资源取值。其中，资源ID可以用于标识一个资源项，资源项可以为主题参数。例如，资源ID可以是背景颜色的标识，或者图标形状的标识。资源取值可以为资源ID指示的主题参数的具体取值，例如，主题参数为背景颜色时，该主题参数的具体取值(即资源取值)可以为白色(或者用于表示白色的字符)或者灰色(或者用于表示灰色的字符)。
相较于现有技术中不同主题包中的资源标识不同且资源取值不同，在本申请实施例中，不同主题包中的资源标识相同且资源取值不同，这样可以避免根据主题对象的个数选择资源ID，有利于减少代码量，并有利于提高主题切换效率。例如，若针对终端设备的主屏幕存在2个主题对象，终端设备采用这2个主题对象时，主屏幕的背景颜色不同，即这2个主题对象中的路径信息指示的主题包中的资源标识(即背景颜色的标识)的资源取值不同。在现有技术中，虽然这2个主题对象中路径信息指示的主题包中均有背景颜色对应的资源标识，但是其资源标识不能相同。如表1所示，其中一个主题对象中路径信息指示的主题包(如主题包1)中背景颜色对应的资源标识的取值为白色，该资源标识表示为“white_bg”；另一个主题对象中路径信息指示的主题包(如主题包2)中背景颜色对应的资源标识的取值为灰色，该资源标识表示为“gray_bg”。这样在确定或改变主屏幕的背景颜色时，终端设备中存储的代码会针对前述2个主题对象出现不同的代码分支。其中一个分支用于确定资源标识为“white_bg”时，该资源标识对应的取值(即白色)，另一个分支用于确定资源标识为“gray_bg”时，该资源标识对应的取值(即灰色)。
表1
主题包 资源标识 资源取值
主题包1 white_bg 白色
主题包2 gray_bg 灰色
但是在本申请实施例中，前述2个主题对象中路径信息指示的主题包中的资源标识可 以相同且资源取值不同，如表2所示，主题包1和主题包2中的资源标识均为“bg”。这样可以避免根据主题对象的个数选择资源ID，有利于减少代码量，并有利于提高主题切换效率。在安卓操作系统中，不能定义两个相同的资源ID，但是由于本申请实施例中的不同主题对象是通过不同的类加载器加载得到的。因此，即使不同主题包中的资源ID相同，也可以在终端设备中同时加载该不同主题包。这样使得终端设备中可以存在多个处于已加载状态的主题对象，这样可以避免终端设备在检测到主题切换操作时，需要花费一段时间加载待启用主题对象，并在加载完毕之后才能实现主题切换，从而有利于提高主题切换效率和用户体验。
表2
主题包 资源标识 资源取值
主题包1 bg 白色
主题包2 bg 灰色
在一种实现方式中，若在终端设备中添加新的主题包，则该新的主题包中的资源标识与终端设备中已有的主题包中的资源标识相同，该新的主题包中的资源取值与已有的主题包中的资源取值不同。在终端设备的开机过程中，该终端设备可以确定当前存储的主题包的个数(如m)，并对应创建m个类加载器，然后调用该m个类加载器加载主题包(一个类加载器加载一个主题包，不同类加载器加载不同主题包)到内存中，并得到m个主题对象。然后将m个主题对象中的一个主题对象作为当前主题对象。此时，该m个主题对象在终端设备中均处于已加载状态，因此在检测到主题切换操作时，可以立即切换主题对象，有利于提高主题切换效率。其中，m为大于1的正整数。
步骤S203：终端设备将该待启用主题对象切换为终端设备的主题对象。
具体的，终端设备确定待启用主题对象之后，可以将该待启用主题对象切换为终端设备的主题对象。由于在将该待启用主题对象切换为终端设备的主题对象之前，该待启用主题对象处于已加载状态，可以避免在将待启用主题对象切换为终端设备的主题对象之前需要花费一段时间去加载该待启用主题对象，从而有利于提高终端设备的主题切换效率。
需要说明的是，本申请实施例对该待启用主题对象的加载时间不做限定。当该待启用主题对象为操作系统的主题对象时，终端设备可以在开机过程中加载该待启用主题对象，或者，也可以在终端设备的运行负载较低(或者该终端设备较为空闲)时加载该待启用主题对象。当该待启用主题对象为应用程序的主题对象时，终端设备可以在启动该应用程序的过程中加载该待启用主题对象，或者，也可以在该应用程序的运行负载较低(或者该应用程序较为空闲)时加载该待启用主题对象。
在一种实现方式中，终端设备可以存储有多个主题对象，终端设备可以同时加载该多个主题对象，也可以根据终端设备的运行状态加载该多个主题对象。具体的，可以根据终端设备的负载量确定可以同时加载的主题对象数量。例如，当终端设备中存储有10个主题对象，且该终端设备的负载量较高时，终端设备可以先加载1个主题对象，然后在终端设备的负载量降低到较低值时，加载剩余的9个主题对象或者该9个主题对象中的部分主题对象。
通过实施本申请实施例，在检测到主题切换操作时，通过获取切换参数，并根据该切 换参数确定待启用主题对象，该待启用主题对象处于已加载状态，然后将该待启用主题对象切换为终端设备的主题对象。由于在将待启用主题对象切换为终端设备的主题对象之前，该待启用主题对象处于已加载状态，可以避免在将待启用主题对象切换为终端设备的主题对象之前需要花费时间去加载该待启用主题对象，从而有利于提高终端设备的主题切换效率。
请参见图3a，图3a是本申请实施例提供的另一种主题切换方法的流程示意图，该方法详细描述了主题切换操作包括哪些操作，以及切换参数包括折叠操作的折叠角度时，如何根据该折叠操作的折叠角度确定待启用主题对象。其中，该主题切换方法的执行主体为终端设备，或者为终端设备中的芯片，以下以终端设备为主题切换方法的执行主体为例进行说明。如图3a所示，该方法可以包括但不限于如下步骤：
步骤S301：在检测到主题切换操作时，终端设备获取切换参数，其中，该终端设备包括折叠屏，该折叠屏包括第一屏幕和第二屏幕；该主题切换操作包括如下操作中的一种或多种：对该折叠屏的折叠操作；使前述第一屏幕和前述第二屏幕之间的折叠角度变化为第一预设角度的折叠操作；使该第一屏幕和该第二屏幕之间的折叠角度的变化量达到第二预设角度的折叠操作；该切换参数包括折叠操作的折叠角度。
在本申请实施例中，终端设备中的折叠屏可以包括一个或多个屏幕，该折叠屏经过折叠之后可以呈现为两个或两个以上屏幕，本申请实施例以该折叠屏经过折叠之后呈现为两个屏幕(如第一屏幕和第二屏幕)为例进行介绍。该主题切换操作可以包括如下操作中的一种或多种：针对终端设备中的预设切换按钮的触发操作(如点击、长按或滑动操作)；对终端设备的翻转操作(对终端设备的翻转操作会使得终端设备的翻转角度发生变化)；对该折叠屏的折叠操作，即使前述第一屏幕和前述第二屏幕之间的折叠角度变化的折叠操作；使该第一屏幕和该第二屏幕之间的折叠角度变化为第一预设角度的折叠操作；使该第一屏幕和该第二屏幕之间的折叠角度的变化量达到(即大于或等于)第二预设角度的折叠操作。终端设备在检测到上述操作中的至少一种时，表示需要切换终端设备的主题对象。
其中，当主题切换操作为对该折叠屏的折叠操作时，只要第一屏幕和第二屏幕之间的折叠角度发生变化，即可以切换终端设备的主题对象，这样可以增加终端设备的趣味性。当主题切换操作为使第一屏幕和第二屏幕之间的折叠角度变化为第一预设角度的折叠操作时，仅当第一屏幕和第二屏幕之间的折叠角度变化为某些特定的角度(即第一预设角度)时，才切换终端设备的主题对象。当主题切换操作为使该第一屏幕和该第二屏幕之间的折叠角度的变化量达到第二预设角度的折叠操作时，可以避免终端设备发生碰撞或因其他原因使折叠屏发生抖动时(此时用户并不希望切换终端设备的主题对象)，导致第一屏幕和第二屏幕之间的折叠角度发生变化，进而使终端设备的主题发生切换的情况，有利于避免误操作。
以图3b为例，图3b是对图1a所示的终端设备100进行折叠操作的场景示意图。由图3b可知，通过转动终端设备100中的转轴31，可以使第一屏幕32和第二屏幕33之间的折叠角度发生变化。当第一屏幕和第二屏幕合成为一个完整的屏幕时，折叠角度为0。往屏幕的后方旋转可以使折叠角度增大。需要说明的是，图3b中所示终端设备包括一个转轴， 且该转轴31在终端设备的中间位置仅用于举例说明，在其他可行的实现方式中，终端设备可以包括多个转轴，该多个转轴可以按需设置在终端设备中的任意位置。可选的，终端设备可以包括无限个转轴，即可以在任意位置处折叠终端设备的屏幕。还需要说明的是，图3b所示第一屏幕和第二屏幕的尺寸相同仅用于举例，并不构成对本申请实施例的限定，在其他可行的实现方式中，第一屏幕和第二屏幕的尺寸可以不同。其中，屏幕的尺寸可以指屏幕的长度、宽度和长宽比中的一种或多种。
其中，第一预设角度和第二预设角度均可以由终端设备默认设置，也可以根据用户操作确定，且可以根据用户操作更改第一预设角度。第一预设角度和第二预设角度均可以是[0°，360°]中的任意角度，在图3b所示的终端设备中，第一预设角度和第二预设角度均可以为[0°，180°]中的任意角度。第一预设角度的数量可以为一个或多个，例如，第一预设角度可以包括90°和180°。第二预设角度可以为1°、2°或者其他较小的角度值。
在本申请实施例中，当终端设备检测到主题切换操作，且主题切换操作为上述3种折叠操作(对该折叠屏的折叠操作，即使第一屏幕和第二屏幕之间的折叠角度变化的折叠操作；使该第一屏幕和该第二屏幕之间的折叠角度变化为第一预设角度的折叠操作；使该第一屏幕和该第二屏幕之间的折叠角度的变化量达到第二预设角度的折叠操作)中的任意一种时，终端设备可以将折叠操作的折叠角度作为切换参数，或者，将折叠操作的折叠角度差作为切换参数。其中，折叠操作的折叠角度可以为执行该折叠操作之后，第一屏幕和第二屏幕之间的折叠角度。折叠操作的折叠角度差为执行该折叠操作之前第一屏幕和第二屏幕之间的折叠角度，与执行该折叠操作之后第一屏幕和第二屏幕之间的折叠角度之间的差值。在一种实现方式中，切换参数可以为终端设备检测到主题切换操作时，生成的随机数。
需要说明的是，步骤S301的其余执行过程可参见图2a中步骤S201的具体描述，此处不再赘述。
步骤S302：终端设备根据折叠角度和主题对象之间的对应关系，将该折叠操作的折叠角度对应的主题对象作为待启用主题对象。
具体的，终端设备获取折叠操作的折叠角度之后，可以根据终端设备预设的折叠角度和主题对象之间的对应关系，将该折叠操作的折叠角度对应的主题对象作为待启用主题对象。
在一种实现方式中，一个主题对象可以与一个或多个折叠角度对应。例如，当主题切换操作为使该第一屏幕和该第二屏幕之间的折叠角度的变化量达到第二预设角度的折叠操作，且第二预设角度为5°时，折叠角度和主题对象之间的对应关系可以如表3所示。
表3
折叠角度 主题对象
[0°，4°] 主题对象1
[5°，9°] 主题对象2
… …
在一种实现方式中，当切换参数包括折叠操作的折叠角度差时，终端设备可以根据预设的折叠角度差和主题对象之间的对应关系，将该折叠操作的折叠角度差对应的主题对象作为待启用主题对象。在一种实现方式中，当切换参数包括终端设备检测到主题切换操作 时生成的随机数时，终端设备可以根据预设的随机数和主题对象之间的对应关系，将终端设备检测到主题切换操作时生成的随机数对应的主题对象作为待启用主题对象。
步骤S303：终端设备将该待启用主题对象切换为终端设备的主题对象。
具体的，终端设备确定待启用主题对象之后，可以将该待启用主题对象切换为终端设备的主题对象。在一种实现方式中，终端设备包括第一屏幕和第二屏幕时，将该待启用主题对象切换为终端设备的主题对象的具体实施方式可以为：将该待启用主题对象切换为第一屏幕和第二屏幕的主题对象。通过这种方式，可以同时切换第一屏幕和第二屏幕的主题对象。
在本申请实施例中，终端设备包括第一屏幕和第二屏幕，该第一屏幕和第二屏幕可以共同显示一个界面，也可以显示不同的界面。例如，当第一屏幕和第二屏幕之间的折叠角度较小时，该第一屏幕和第二屏幕可以共同显示一个界面(如主屏幕界面或者某应用的界面)，如图3b中在折叠第二屏幕33之前，第一屏幕32和第二屏幕33可以共同显示主屏幕界面。又如，当第一屏幕和第二屏幕之间的折叠角度较大，或者，终端设备需要同时显示多个界面(如两个界面)时，第一屏幕和第二屏幕可以显示不同的界面。例如，第一屏幕可以显示终端设备中运行的应用程序a的界面，第二屏幕可以显示终端设备中运行的应用程序b的界面，其中，应用程序a的界面和应用程序b的界面不同。
在一种实现方式中，终端设备包括第一屏幕和第二屏幕，且检测到主题切换操作时，第一屏幕和第二屏幕显示不同的界面时，终端设备需要分别确定第一屏幕对应的待启用主题对象和第二屏幕对应的待启用主题对象，进而将第一屏幕对应的待启用主题对象切换为第一屏幕的主题对象，并将第二屏幕对应的待启用主题对象切换为第二屏幕的主题对象。
其中，若在检测到主题切换操作时，该第一屏幕中显示的界面为操作系统的界面，则将第一屏幕对应的待启用主题对象切换为第一屏幕的主题对象表示：将第一屏幕对应的待启用主题对象切换为该操作系统的主题对象。若在检测到主题切换操作时，该第一屏幕中显示的界面为某应用程序的界面，则将第一屏幕对应的待启用主题对象切换为第一屏幕的主题对象表示：将第一屏幕对应的待启用主题对象切换为该应用程序的主题对象。
需要说明的是，终端设备需要分别确定第一屏幕对应的待启用主题对象和第二屏幕对应的待启用主题对象时，若切换参数包括折叠操作的折叠角度，终端设备可以根据折叠角度和主题对象之间的对应关系确定第一屏幕对应的待启用主题对象和第二屏幕对应的待启用主题对象；或者，根据不同的(折叠角度和主题对象之间的)对应关系分别确定第一屏幕对应的待启用主题对象和第二屏幕对应的待启用主题对象。同理，若切换参数包括折叠操作的折叠角度差，终端设备可以根据折叠角度差和主题对象之间的对应关系确定第一屏幕对应的待启用主题对象和第二屏幕对应的待启用主题对象；或者，根据不同的(折叠角度差和主题对象之间的)对应关系分别确定第一屏幕对应的待启用主题对象和第二屏幕对应的待启用主题对象。
在一种实现方式中，随着用户旋转第一屏幕和/或第二屏幕，以使得第一屏幕和第二屏幕之间的折叠角度变化时，终端设备根据折叠角度和主题对象之间的对应关系，确定出待启用主题对象。在折叠角度不同时，确定出的待启用主题对象不同。当终端设备将该不同的待启用主题对象切换为该终端设备的主题对象时，该终端设备的屏幕中显示的背景颜色 可以不同。例如，随着折叠角度越来越大，终端设备的屏幕中显示的背景颜色可以越来越深，或者越来越浅。这样可以在用户旋转屏幕的过程中，给用户更多的屏幕反馈，有利于提高用户体验并增强终端设备的趣味性。
在一种实现方式中，当终端设备包括折叠屏，且该折叠屏包括第一屏幕和第二屏幕时，终端设备将待启用主题对象切换为该终端设备的主题对象的具体实施方式可以为：将该待启用主题对象切换为前述主题切换操作所操作的屏幕的主题对象。通过这种方式，可以在用户仅翻转终端设备包括的多个屏幕中的部分屏幕时，仅切换被用户翻转的屏幕的主题对象。
其中，主题切换操作所操作的屏幕可以为第一屏幕和/或第二屏幕。当主题切换操作为针对终端设备中的预设切换按钮的触发操作(如点击、长按或滑动操作)时，该主题切换操作所操作的屏幕可以为该预设切换按钮所在的屏幕。当主题切换操作为对终端设备的翻转操作时，该主题切换操作所操作的屏幕为第一屏幕和第二屏幕。以图3b为例，当用户将第二屏幕33往后翻转，且主题切换操作为对该折叠屏的折叠操作时，该主题切换操作所操作的屏幕为第二屏幕。当用户将第二屏幕33往后翻转使第一屏幕32和第二屏幕33之间的折叠角度变化为第一预设角度，且主题切换操作为使该第一屏幕和该第二屏幕之间的折叠角度变化为第一预设角度的折叠操作时，该主题切换操作所操作的屏幕为第二屏幕。当用户将第二屏幕33往后翻转使第一屏幕32和第二屏幕33之间的折叠角度的变化量大于或等于第二预设角度，且主题切换操作为使该第一屏幕和该第二屏幕之间的折叠角度的变化量达到第二预设角度的折叠操作时，该主题切换操作所操作的屏幕为第二屏幕。
在一种实现方式中，当终端设备可以包括折叠屏，且该折叠屏可以包括第一屏幕和第二屏幕，待启用主题对象可以包括第一主题对象和第二主题对象，该第一主题对象和该第二主题对象之间存在关联关系时，终端设备将待启用主题对象切换为该终端设备的主题对象的具体实施方式可以为：将该第一主题对象切换为第一屏幕的主题对象，并将该第二主题对象切换为第二屏幕的主题对象。
其中，当该折叠屏包括N个屏幕时，待启用主题对象可以包括N个主题对象，该N个主题对象可以为一组主题对象，同一组主题对象中的各个主题对象之间存在关联关系。通过采用一组具有关联关系的主题对象，有利于增强终端设备的趣味性。其中，N可以为任意正整数。
当待启用主题对象包括第一主题对象和第二主题对象，且该第一主题对象作为第一屏幕的主题对象，该第二主题对象作为第二屏幕的主题对象，第一屏幕和第二屏幕之间的折叠角度为30°时，以图3c所示的第一屏幕和第二屏幕中显示的背景图像的示意图为例。由图3c可知，该第一屏幕32的背景图像为一个小男孩，该第二屏幕33的背景图像为一个小女孩，该小男孩和小女孩之间的距离较远。
当用户旋转第一屏幕和/或第二屏幕，以使得第一屏幕和第二屏幕之间的折叠角度为0°时，该第一屏幕和第二屏幕中显示的背景图像的示意图如图3d所示。由图3d可知，第一屏幕和第二屏幕之间的折叠角度由30°减小为0°时，该小男孩和小女孩之间的距离变小。需要说明的是，终端设备可以根据第一屏幕和第二屏幕之间的折叠角度确定第一主题对象和第二主题对象。在图3c和图3d所示例子中，随着第一屏幕和第二屏幕之间的折叠角度 变小，确定出第一主题对象和第二主题对象，且该第一主题对象作为第一屏幕的主题对象，该第二主题对象作为第二屏幕的主题对象时，随着第一屏幕和第二屏幕之间的折叠角度变小，小男孩和小女孩之间的距离也变近。这样可以在旋转第一屏幕和/或第二屏幕，以使得第一屏幕和第二屏幕之间的折叠角度越来越小时，使用户看到小男孩和小女孩之间的距离越来越近的动态效果，有利于提高终端设备的趣味性。
在一种实现方式中，当该折叠屏包括N个屏幕，且待启用主题对象包括N个主题对象时，该N个主题对象中的各个主题对象之间可以相互独立，即各个主题对象之间不存在关联关系。
通过实施本申请实施例，在检测到折叠操作时，通过获取折叠操作的折叠角度，并根据折叠角度和主题对象之间的对应关系，将该折叠操作的折叠角度对应的主题对象作为待启用主题对象，该待启用主题对象处于已加载状态，然后将该待启用主题对象切换为终端设备的主题对象。由于在将待启用主题对象切换为终端设备的主题对象之前，该待启用主题对象处于已加载状态，可以避免在将待启用主题对象切换为终端设备的主题对象之前需要花费时间去加载该待启用主题对象，从而有利于提高终端设备的主题切换效率。
请参见图4，图4是本申请实施例提供的又一种主题切换方法的流程示意图，该方法详细描述了切换参数包括折叠操作的折叠角度和辅助信息时，如何根据该折叠操作的折叠角度和辅助信息确定待启用主题对象。其中，该主题切换方法的执行主体为终端设备，或者为终端设备中的芯片，以下以终端设备为主题切换方法的执行主体为例进行说明。如图4所示，该方法可以包括但不限于如下步骤：
步骤S401：在检测到主题切换操作时，终端设备获取切换参数，其中，该终端设备包括折叠屏，该折叠屏包括第一屏幕和第二屏幕；该主题切换操作包括如下操作中的一种或多种：对该折叠屏的折叠操作；使前述第一屏幕和前述第二屏幕之间的折叠角度变化为第一预设角度的折叠操作；使该第一屏幕和该第二屏幕之间的折叠角度的变化量达到第二预设角度的折叠操作；该切换参数包括折叠操作的折叠角度和辅助信息，该辅助信息包括：时间信息、日期信息和天气信息中的一种或多种。
在本申请实施例中，当终端设备检测到主题切换操作，且主题切换操作为上述3种折叠操作(对该折叠屏的折叠操作，即使第一屏幕和第二屏幕之间的折叠角度变化的折叠操作；使该第一屏幕和该第二屏幕之间的折叠角度变化为第一预设角度的折叠操作；使该第一屏幕和该第二屏幕之间的折叠角度的变化量达到第二预设角度的折叠操作)中的任意一种时，切换参数可以包括折叠操作的折叠角度(或者折叠操作的折叠角度差、终端设备检测到主题切换操作时生成的随机数)和辅助信息。
其中，该辅助信息可以包括但不限于：时间信息、日期信息、天气信息和该终端设备中安装的某一个或多个应用程序中的应用信息中的一种或多种。例如，该应用程序可以为记录节假日的应用、记录用户心情的应用等。需要说明的是，步骤S401的其余执行过程可参见图3a中步骤S301的具体描述，此处不再赘述。
步骤S402：终端设备根据折叠角度和主题对象集合之间的对应关系，确定与该折叠操作的折叠角度对应的目标主题对象集合。
具体的，当切换参数包括折叠操作的折叠角度和辅助信息时，终端设备获取该折叠操作的折叠角度和辅助信息之后，可以根据预设的折叠角度和主题对象集合之间的对应关系，确定与该折叠操作的折叠角度对应的目标主题对象集合；进而根据该辅助信息，从该目标主题对象集合中确定待启用主题对象。其中，每个主题对象集合均包括两个或两个以上的主题对象。不同主题对象集合包括的主题对象可以完全不同，也可以不完全相同。例如，主题对象集合a包括主题对象1和主题对象2，主题对象集合b包括主题对象1和主题对象3。
采用不同主题对象集合中的主题对象时，在终端设备的显示屏中至少有一个主题参数不同。例如，当折叠操作的折叠角度大于0°时(即折叠屏处于折叠状态时)，根据该折叠操作的折叠角度确定出的目标主题对象集合为主题对象集合a，终端设备将主题对象集合a中的任意一个主题对象作为该终端设备的主题对象时，该终端设备的主屏幕的背景颜色可以显示为黑色。当折叠操作的折叠角度为0°时(即折叠屏处于展开状态时)，根据该折叠操作的折叠角度确定出的目标主题对象集合为主题对象集合b，终端设备将主题对象集合b中的任意一个主题对象作为该终端设备的主题对象时，该终端设备的主屏幕的背景颜色可以显示为白色。换言之，主题对象集合a包括多个黑夜主题对象，主题对象集合b包括多个白天主题对象。
终端设备将目标主题对象集合中的不同主题对象作为该终端设备的主题对象时，在该终端设备的显示屏中至少有一个主题参数不同。例如，目标主题对象集合包括多个白天主题对象时，终端设备将该多个白天主题对象中的不同白天主题对象作为该终端设备的主题对象时，在该终端设备的显示屏中显示的主屏幕的背景图片和/或图标形状可以不同。
步骤S403：终端设备根据该辅助信息，从该目标主题对象集合中确定待启用主题对象。
具体的，终端设备确定目标主题对象集合之后，可以根据该辅助信息，从该目标主题对象集合中确定待启用主题对象。例如，当该辅助信息包括日期信息，且终端设备中的日期信息为9月10日时，终端设备可以确定当日为教师节。若目标主题对象集合包括多个白天主题对象，则终端设备可以将该多个白天主题对象中与教师节对应的主题对象作为待启用主题对象。进而将该待启用主题对象切换为该终端设备的主题对象，使得该终端设备的屏幕中可以显示教师节相关的背景图片，这样有利于提高终端的趣味性。
又如，当该辅助信息包括天气信息，且该天气信息记录当前的天气为晴朗时，若目标主题对象集合包括多个白天主题对象，则终端设备可以将该多个白天主题对象中与晴朗天气对应的主题对象作为待启用主题对象。进而将该待启用主题对象切换为该终端设备的主题对象，使得该终端设备的屏幕中可以显示与晴朗天气相关的背景图片(如太阳图片)，这样有利于提高终端的趣味性。
又如，当该辅助信息包括记录用户心情的应用中的应用信息，且该应用信息记录用户当前的天气较差时，若目标主题对象集合包括多个白天主题对象，则终端设备可以将该多个白天主题对象中与愉悦心情对应的主题对象作为待启用主题对象。进而将该待启用主题对象切换为该终端设备的主题对象，使得该终端设备的屏幕中可以显示与愉悦心情相关的背景图片，这样可以使用户看到该背景图片时，心情变好，同时也有利于提高终端的趣味性。
需要说明的是，前述教师节相关的背景图片、与晴朗天气相关的背景图片和与愉悦心情相关的背景图片均可以包括一个或多个图像，当包括多个图像时，在终端设备中显示为一个动态图像。
步骤S404：终端设备将该待启用主题对象切换为终端设备的主题对象。
需要说明的是，步骤S404的执行过程可参见图3a中步骤S303的具体描述，此处不再赘述。
通过实施本申请实施例，在检测到折叠操作时，通过获取折叠操作的折叠角度和辅助信息，并根据折叠角度和主题对象之间的对应关系，确定与该折叠操作的折叠角度对应的目标主题对象集合；进而根据该辅助信息，从该目标主题对象集合中确定待启用主题对象，该待启用主题对象处于已加载状态，然后将该待启用主题对象切换为终端设备的主题对象。由于在将待启用主题对象切换为终端设备的主题对象之前，该待启用主题对象处于已加载状态，可以避免在将待启用主题对象切换为终端设备的主题对象之前需要花费时间去加载该待启用主题对象，从而有利于提高终端设备的主题切换效率。另外，根据该辅助信息，从该目标主题对象集合中确定待启用主题对象，有利于提高终端的趣味性。
