Specifically, some applications need to maintain interface consistency and functionality across devices of different sizes. However, some devices (such as foldable devices) have different screen sizes and aspect ratios than traditional devices. Therefore, display compatibility issues arise when the application's interface design is only for traditional standard-sized screens. To solve this problem, LetterBox can fill a portion of the screen (such as a second section) to ensure that the application interface is not distorted or stretched due to differences in device screens.
  • LetterBox registers a listener service with the Task management module to indicate when the first window is drawn.
  • LetterBox after receiving the notification from WMS to refresh the background color of the second partition, LetterBox needs to wait for the first window to be displayed in the first partition to be drawn before it can complete the refresh task of the second partition based on the object of the first window. Therefore, LetterBox also needs to register a listener service for the completion of the drawing of the focus window with the Task management module.

Description

屏幕分区显示方法、图形界面及电子设备 技术领域
本申请涉及终端领域，尤其涉及一种屏幕分区显示方法、图形界面及电子设备。
背景技术
目前，越来越多的电子设备具备屏幕和各种传感模器，若将屏幕和传感器设计在电子设备的同一面，则屏幕与传感器的设计区域存在冲突。
那么，在电子设备的同一面设置有传感器和屏幕的情况下，如何在设计空间受限的情况下，既提供一种空间利用率较大的屏幕，又能够提升屏幕的显示效果。
发明内容
本申请提供了一种屏幕分区显示方法、图形界面及电子设备。该方法应用于包括传感器和屏幕的电子设备，该屏幕包括设置在同一面的第一分区和第二分区，第一分区不包括打孔区域，第二分区包括用于设置传感器的打孔区域。电子设备运行应用时，在第一分区显示应用的窗口，在第二分区显示与第一分区中应用的窗口相适配的背景色。其中，第二分区显示的背景色为以下任意一种：由第一分区中应用的开发者自配置，由电子设备为该应用预配置，由电子设备从第一分区中应用的窗口实时提取的背景基础色结合预配置的背景叠加色得到的，或者由电子设备从第一分区中应用的窗口实时提取的背景基础色等。
第一方面，一种屏幕分区显示方法，该方法应用于包括第一屏幕的电子设备，该第一屏幕包括第一分区和第二分区，该第一分区不包括打孔区域，该第二分区包括打孔区域，该方法包括：运行第一应用时，在该第一分区显示该第一应用提供的第一窗口，在该第二分区显示第一背景，该第一背景的色彩值和该第一窗口中第一视图的色彩值相同或相近；其中，该第一视图满足以下一个或多个条件：该第一视图在该第一窗口中的图层数为第N层以上，该第一视图处于可见状态，该第一视图的面积大于第一值，或者，该第一视图的背景非空；接收到第一操作，运行第二应用；运行该第二应用时，在该第一分区中显示该第二应用的第二窗口，在该第二分区中显示第二背景，该第二背景的色彩值和该第二窗口中第二视图的色彩值相同或相近。
实施第一方面描述的方法，通过充分利用电子设备的设计区域，提供几近全屏显示的能力。弱化屏幕中用于设置传感器的打孔区域对显示效果的影响。具体的，将屏幕划分为包含打孔区域的第二分区和不含打孔区域的第一分区，然后分区显示不同内容，并且使得第二分区的背景色与第一分区中应用窗口相适配，既弱化屏幕分区间的割裂感以营造全屏联合显示效果。
结合第一方面描述的方法，该第一背景仅包含色彩元素，不包含图案元素。
这样，可以避免第二分区的显示元素过于复杂，分散用户的注意力，帮助用户聚焦关键的第一分区的内容，不影响用户的主任务交互。
结合第一方面描述的方法，该第一窗口用于显示以下一项：社交类应用的主页、社交 类应用的聊天页面、社交类应用的设置页面、音乐类应用的主页、音乐类应用的播放界面、音乐类应用的设置界面、视频类应用的主页、视频类应用的播放界面、视频类应用的设置界面、购物类应用的主页、购物类应用的播放界面或者购物类应用的设置界面。
这样，电子设备在第一分区显示任意的应用界面时，第二分区的背景色均可以与第一分区的应用相适配，扩展了本方案的应用场景。
结合第一方面描述的方法，该第一背景的色彩值为该第一应用配置的第一预设值。
这样，电子设备可以为第三方应用提供自配置第二分区背景色的接口，支持第三方应用开发者自定义第二分区中的背景色，从而带来全屏联合显示应用窗口的效果，提升用户的视觉体验。
结合第一方面描述的方法，在该第一应用配置有第一预设值的情况下，该第一背景的色彩值为该第一预设值。在该第一分区显示该第一应用提供的第一窗口之前，通过绘制该第一窗口获取该第一窗口的对象；在该第二分区显示第一背景之前，基于该第一窗口的对象中包含的第一属性值确定该第一背景的色彩值为该第一应用配置的第一预设值。
这样，第一应用的开发人员可以为应用的窗口配置对应的第二分区的背景色。
结合第一方面描述的方法，该第一背景的色彩值为该电子设备配置的第二预设值。
这样，电子设备的开发人员可以预配置应用对应的第二分区的背景色，保证在第一应用的开发人员没有自配置第二分区的背景色的情况下，仍然可以在第二分区显示与第一分区中第一应用相适配的背景色，提升用户的视觉体验。
结合第一方面描述的方法，在该第一应用未配置第一预设值并且该电子设备配置有第二预设值的情况下，该第一背景的色彩值为该第二预设值。该电子设备预置第一白名单，并且，预置该第一白名单中的应用对应的该第二预设值，该方法还包括：在该第一分区显示该第一应用提供的第一窗口之前，通过绘制该第一窗口获取该第一窗口的对象；在该第二分区显示第一背景之前，确定该第一窗口的对象中未包含第一属性值，该第一属性值对应该第一背景的色彩值，并且，确定该第一应用属于该第一白名单，则确定该第一背景的色彩值为该第二预设值。
这样，可以优先采用第一应用自配置的第二分区的背景色，从而优先保证第一应用提供的联合整套的显示效果，但当第一应用没有自配置时，则可以采用电子设备预配置的第二分区的背景色，从而全方位保证第二分区的背景色与第一分区中的第一应用的显示效果相适配。
结合第一方面描述的方法，该第二预设值是，在第三色彩值之上叠加第四色彩值后得到的，该第三色彩值为纯色，该第四色彩值为亮度渐变的白色。
这样，通过在纯色的基础上叠加亮度渐变的白色，将第一分区和第二分区的显示效果做出轻微区别，既不会带给用户视觉割裂感，又能保证一定的视觉融合体验。
结合第一方面描述的方法，该第一背景的色彩值为，根据该电子设备配置的第三预设值和根据该第一窗口中第一视图的色彩值确定。
这样，可以避免从第一窗口的第一视图中智能提取的色彩过于单调，进而叠加电子设备预置的第三预设值，可以带给用户丰富的视觉体验。
结合第一方面描述的方法，在该第一应用未配置第一预设值、该电子设备未配置第二 预设值并且该电子设备配置有第三预设值的情况下，该第一背景的色彩值为，根据该电子设备配置的第三预设值和根据该第一窗口的色彩值确定。该电子设备预置第一白名单和第二白名单，并且，预置该第一白名单中的应用对应的该第二预设值，预置该第二白名单中的应用对应的该第三预设值，该方法还包括：在该第一分区显示该第一应用提供的第一窗口之前，通过绘制该第一窗口获取该第一窗口的对象；在该第二分区显示第一背景之前，确定该第一窗口的对象中未包含第一属性值，该第一属性值对应该第一背景的色彩值，并且，确定该第一应用不属于该第一白名单且属于该第二白名单，则确定该第一背景的色彩值为，根据该第三预设值和根据该第一窗口中第一视图的色彩值确定。
这样，优先采用第一应用自配置的第二分区的背景色，第一应用未自配置则采用电子设备预配置的第二分区的背景色，若电子设备仅预配置的第二分区的背景叠加色(即第三预设值)，则还需要从第一应用的第一窗口中智能提取背景基础色，如此可以全方位的保证第二分区的背景色能够随着第一分区中的应用动态适配。
结合第一方面描述的方法，该第一背景的色彩值为在第三色彩值之上叠加该第三预设值后得到的，该第三色彩值为根据该第一窗口中第一视图的色彩值确定的纯色，该第三预设值为亮度渐变的白色。
这样，通过在纯色的基础上叠加亮度渐变的白色，将第一分区和第二分区的显示效果做出轻微区别，既不会带给用户视觉割裂感，又能保证一定的视觉融合体验。
结合第一方面描述的方法，该第一窗口中的第一视图为第四色彩值；该第三色彩值为通过调整该第四色彩值的亮度确定，当该第四色彩值的亮度大于第二值(例如0％)并且小于第三值(例如50％)时，则该第三色彩值的亮度为该第三值，当该第四色彩值的亮度属于大于或等于该第三值，并且小于第四值(例如100％)时，则该第三色彩值的亮度为该第四值。
这样，在从第一窗口的第一视图中提取背景基础色时，可以选取与第一视图的色彩值相近似的色彩值作为背景基础色，这样可以使得第二分区的背景色与第一分区相近但有轻微区别，从而不会过于干扰用户关注第一分区中的关键信息。
结合第一方面描述的方法，该第一背景的色彩值为根据该第一窗口中第一视图的色彩值确定。
结合第一方面描述的方法，在该第一应用未配置第一预设值、该电子设备未配置第二预设值并且该电子设备未配置第三预设值的情况下，该第一背景的色彩值根据该第一窗口中第一视图的色彩值确定。该电子设备预置第一白名单和第二白名单，并且，预置该第一白名单中的应用对应的该第二预设值，预置该第二白名单中的应用对应的该第三预设值，该方法还包括：在该第一分区显示该第一应用提供的第一窗口之前，通过绘制该第一窗口获取该第一窗口的对象；在该第二分区显示第一背景之前，确定该第一窗口的对象中未包含第一属性值，该第一属性值对应该第一背景的色彩值，并且，确定该第一应用不属于该第一白名单且不属于该第二白名单，则根据该第一窗口中第一视图的色彩值确定该第一背景的色彩值。
这样，可以全方位的保证第二分区的背景色能够随着第一分区中的应用动态适配。
结合第一方面描述的方法，该第一窗口中的第一视图为第四色彩值；该第一背景的色 彩值为通过调整该第四色彩值的亮度确定，当该第四色彩值的亮度大于第二值并且小于第三值时，则该第一背景的色彩值的亮度为该第三值，当该第四色彩值的亮度属于大于或等于该第三值，并且小于第四值时，则该第一背景的色彩值的亮度为该第四值。
这样，在从第一窗口的第一视图中提取背景基础色时，可以选取与第一视图的色彩值相近似的色彩值作为背景基础色，这样可以使得第二分区的背景色与第一分区相近但有轻微区别，从而不会过于干扰用户关注第一分区中的关键信息。
结合第一方面描述的方法，在该第二分区中显示该第一背景之前，该方法还包括：确定该第一应用的显示模式被设置为浅色模式。
由于深色模式下，第一分区中第一应用的界面的显示模式均为深色，无需对第二分区的背景色做额外的处理，随第一分区显示深色即可，只有在第一应用的显示模式为浅色模式时，才采用前述显示方法控制第二分区的背景色。
结合第一方面描述的方法，在该第二分区显示第一背景时，该方法还包括：在该第二分区中还显示该电子设备的状态信息。
这样，采用第二分区显示对屏幕的规则度完整度要求不高的内容，如电子设备的状态信息，可以避免打孔区域对显示内容的影响。
结合第一方面描述的方法，在运行第一应用之前，该方法还包括：在该第一分区和该第二分区中显示桌面的背景，在该第一分区中还显示该桌面的应用图标，在该第二分区中还显示该电子设备的状态信息。
这样，在电子设备显示桌面是，可以通过第一分区和第二分区联合显示桌面背景。
结合第一方面描述的方法，在获取第一应用对应的该第二分区中的第一色彩值之前，该方法还包括：检测到该第一窗口切换为焦点窗口。
这样，可以及时检测到第一分区中将要切换应用的窗口，从而及时调整第二分区的背景色，保证屏幕分区显示效果的实时性和有效性。
结合第一方面描述的方法，该第一屏为该电子设备的外屏。
第二方面，本申请提供了一种电子设备，包括一个或多个存储器，一个或多个处理器，以及存储在该存储器上的计算机程序，显示屏，该处理器执行该计算机程序以实现第一方面中任一项所描述的步骤。
第三方面，本申请提供了一种计算机可读存储介质，其上存储有计算机程序，该计算机程序被处理器执行时以实现第一方面中任一项所描述的步骤。
第四方面，本申请提供了一种计算机程序产品，包括计算机程序/指令，该计算机程序被处理器执行时以实现第一方面中任一项所描述的步骤。

具体实施方式
下面将结合附图对本申请实施例中的技术方案进行清楚、详尽地描述。其中，在本申请实施例的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B；文本中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为暗示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征，在本申请实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在本申请中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本申请所描述的实施例可以与其它实施例相结合。
本申请以下实施例中的术语“用户界面(user interface，UI)”，是应用程序或操作系统与用户之间进行交互和信息交换的介质接口，它实现信息的内部形式与用户可以接收形式之间的转换。用户界面是通过java、可扩展标记语言(extensible markup language，XML)等特定计算机语言编写的源代码，界面源代码在电子设备上经过解析，渲染，最终呈现为用户可以识别的内容。用户界面常用的表现形式是图形用户界面(graphic user interface，GUI)，是指采用图形方式显示的与计算机操作相关的用户界面。它可以是在电子设备的显示屏中显示的文本、图标、按钮、菜单、选项卡、文本框、对话框、状态栏、导航栏、Widget等可视的界面元素。
目前，用户对电子设备中传感器的功能、数量等的需求较高，为此，传感器在电子设备中的设计区域越来越大，相应的，导致屏幕在电子设备中的设计区域受到了限制。以传感器为电子设备的摄像头，屏幕为电子设备的外屏为例，该外屏的设计区域受到摄像头的限制，具体可参考图1。
图1示例性示出一种屏幕结构。
图1所示的电子设备为可折叠的电子设备，该电子设备的屏幕包括内屏和外屏，内屏是指电子设备处于展开状态时所运行的屏幕，外屏是指电子设备处于折叠状态时所运行的屏幕。在外屏和摄像头均设置在电子设备的同一面(即外壳所在的一面)的情况下，为了既保证摄像功能的正常实现，又保证摄像头不影响外屏的显示效果，则采用摄像头所在区域以外的，规则且完整的区域作为外屏的设计区域。其中，规则区域特指例如矩形、圆形等的区域，完整的区域是指无孔洞的单联通区域，这样才可以保证显示效果的完整性和规则性。
图1仅以一个示例性的场景来介绍该种屏幕设计方法，类似的，在电子设置其他类型的传感器、屏幕的场景下，若传感器和屏幕需要设计在电子设备的同一面，均可能采用如图1所示的屏幕设计方法，在此暂不一一举例。
基于图1所示的屏幕设计可知，在电子设备的传感器与屏幕的设计区域存在冲突的情况下，虽然图1所示的屏幕设计可以提供规则的显示区域，但是该屏幕设计没能充分利用电子设备的设计区域，即，没有充分利用摄像头的周边区域，这样设计出的屏幕较小，带给用户的交互体验不佳。
为了解决图1所示的屏幕结构所存在的问题，本申请提供了另一种改进后的屏幕结构。接下来，结合图2来介绍本申请提供的屏幕分区显示方法所涉及的屏幕结构。
图2示例性示出另一种屏幕结构。
如图2所示，本申请提供的显示方法应用于电子设备100。该电子设备100的屏幕包括内屏和外屏(又称第一屏幕)，内屏是指电子设备100处于展开状态时所运行的屏幕，外屏是指电子设备100处于折叠状态时所运行的屏幕。对比图1和图2中的屏幕设计可知，图2中的屏幕设计充分利用了可设计空间，将外屏的设计面积延展至传感器的四周。在提供较大外屏的基础上，也带来了外屏的显示效果上的挑战。即，虽然外屏的面积更大，但是外屏并非一个完整的区域，其中包含孔/洞，外屏被挖孔/洞则会影响屏幕中内容被完整、规则的显示。
基于此，在扩展外屏面积的基础上，为了进一步避免外屏中用于设置传感器的孔/洞影响显示内容的完整性，本申请进一步将外屏划分为多个区域，然后分区显示不同类型的内容，从而尽可能的减少屏外屏中的孔/洞对显示内容完整性的影响。可选的，可将外屏划分为第一分区和第二分区，第一分区为单联通区域(即无孔区域)，第二分区为多联通区域(即有孔/洞区域)，第二分区中的孔/洞用于设置传感器，在电子设备运行应用时，采用第一分区显示对屏幕的规则度完整度要求较高的内容，如应用界面，采用第二分区显示对屏幕的规则度完整度要求不高的内容，如电子设备的状态信息(具体可参见后文对图3A-图3D的描述)，这样的屏幕分区显示方法可以避免打孔区域处的传感器对屏幕显示内容的影响。关于具体的屏幕分区显示方法可以参考下文对图5-图6的介绍，关于屏幕分区显示的用户界面可以参考后文图3A-图4D的UI实施例。
图2仅示例性示出本申请提供的一种屏幕设计，不应构成对本申请的限制，本申请提供的屏幕分区显示方法还可以应用在其他屏幕设计中，具体如下：
在本申请提供的其他屏幕设计中，第二分区和第一分区的划分方向除了纵向划分外还可以横向划分，屏幕的分区划分方向具体取决于传感器的打孔区域的排布方向，若打孔区域为纵向排布，则第二分区和第一分区可以纵向划分；若打孔区域为横向排布的，则第二分区和第一分区可以横向划分。
在本申请提供的其他屏幕设计中，屏幕中的打孔区域的数量还可以是一个或更多个，打孔区域的数量具体取决于对传感器的设计，若打孔区域为一个，则该一个打孔区域可用于设置一个传感器或者可用于设置集成为一体的多个传感器；若打孔区域为多个，则每个打孔区域均可用于设置一个或多个传感器。
在本申请提供的其他屏幕设计中，采用分区设计的屏幕除了外屏以外还可以是内屏，也可以是没有内外屏之分的电子设备100的屏幕(如非折叠式电子设备100的屏幕)。虽然，通常情况下，电子设备100的内屏所在面中所设置的传感器的数量较少、区域较小，即电子设备100内屏所在面的传感器几乎不影响内屏的显示效果，故无需对内屏采用本申请提供的屏幕分区显示方法。但是，在特殊情况下，若电子设备100的内屏所在面中设置的传感器的数量较多、区域较大，则可以采用本申请提供的屏幕分区显示方法。总之，对于传感器和屏幕的设计区域存在冲突的情况，均可以采用本申请提供的屏幕分区设计和屏幕分区显示方法。
基于前述对图2中屏幕分区结构的介绍可知，仅将屏幕进行分区显示不同类型内容时，虽然可以避免打孔区域的传感器影响屏幕显示内容的完整性，但是，分区可能因为显示不同类型的内容而出现视觉割裂感，或者出现混淆用户关注的内容的问题等。在此基础上，为了进一步提高屏幕分区显示效果，还需进一步改进第二分区的显示效果(例如背景色)，旨在既能够带给用户全屏联合显示的视觉体验，增强视觉美感，弱化第二分区与第一分区的割裂感；又可以让用户聚焦第一分区中显示的主任务，弱化第二分区对第一分区的影响。
综上所述，为了解决前述问题，本申请提供了一种屏幕分区显示方法、图形界面及电子设备。该方法应用于包括传感器和屏幕的电子设备，该屏幕包括设置在同一面的第一分区和第二分区，第一分区不包括打孔区域，第二分区包括用于设置传感器的打孔区域。电子设备运行应用时，在第一分区显示应用的窗口，在第二分区显示与第一分区中应用的窗口相适配的背景色。其中，第二分区显示的背景色为以下任意一种：由第一分区中应用的开发者自配置，由电子设备为该应用预配置，由电子设备从第一分区中应用的窗口实时提取的背景基础色结合预配置的背景叠加色得到的，或者由电子设备从第一分区中应用的窗口实时提取的背景基础色等。
接下来，先介绍本申请涉及的一些相关概念。
传感器：可以包括一个或多个图像传感器(即摄像头)，环境光传感器，或者接近光传感器等等。
屏幕：电子设备可以仅配置一个屏幕；或者，当电子设备为折叠式设备时，可以配置两个屏幕，例如，以上下折叠式的电子设备为例，则可以配置内外两个屏幕；或者，当电子设备为折叠式设备时，还可以配置三个屏幕，例如，以左右折叠的电子设备为例，可以配置外屏和内屏，内屏又包括左右两个屏幕。总之，本申请实施例对电子设备的屏幕数量，屏幕是否折叠，以及折叠形式等均不作限制。
第一分区和第一分区：是指一个屏幕中包含的相互连接且互不重叠的两个子区域，关于该两个区域的结构，具体可以参考下文对图2示例性示出的外屏分区结构的描述，在此暂不赘述。
打孔区域是指屏幕中第二分区中的孔/洞，第二分区相当于数理概念中多联通区域，第二分区中的打孔区域相当于数理概念中多联通区域中的孔/洞。
应用的窗口：是指电子设备在运行应用时，构成第一分区中应用界面的窗口，该窗口通过在第一分区中显示以形成用户可视的应用界面。应用界面包括但不限于：主界面(又称一级界面)、二级界面、三级界面等等，每当用户切换应用界面时，电子设备均需通过切换焦点窗口(即，包括将旧的应用界面对应的窗口设置为不可见状态，将新的应用的界面对应的窗口设置为可见状态)来实现切换显示新的用户界面。
背景色：是指在第一分区中显示的界面元素中作为底层的颜色，其可以是单一色彩(即本申请实施例中所述的背景基础色)，也可以是由多种色彩组合而成的色彩(即本申请实施例中所述的背景基础色结合背景叠加色得到色彩)。
电子设备的状态信息：是指在第二分区中显示的时间、日期等信息。
实施本申请提供的显示方法、图形界面及电子设备后，可以带来以下有益效果：
(1)充分利用电子设备的设计区域，兼容设计屏幕和传感器，既保证传感功能的正常实现，又提供几近全屏显示的能力。具体的，在屏幕中进行打孔，将传感器设置在打孔区域处，便可以将传感器周围的区域拓展为屏幕的设计区域。
(2)弱化屏幕中传感器对显示效果的影响。具体的，将屏幕划分为包含打孔区域的第二分区和不含打孔区域的第一分区，然后分区显示不同内容，包括采用第一分区显示对屏幕的规则度完整度要求较高的内容(如应用界面)，采用第二分区显示对屏幕的规则度完整度要求不高的内容(如电子设备的状态信息)。
(3)为第三方应用提供自配置第二分区背景色的接口，支持第三方应用开发者自定义第二分区中的背景色，从而带来全屏联合显示应用窗口的效果，提升用户的视觉体验。
(4)为第二分区预配置与第一分区中应用相匹配的背景色，或者从第一分区中应用智能提取相似色作为第二分区的背景色，从而使得第二分区可以适配第一分区中应用窗口的显示效果，既弱化屏幕分区间的割裂感以营造全屏联合显示效果，又可以聚焦关键分区的内容不影响用户的主任务交互。
接下来，结合图3A-图3D示例性示出几种显示策略对应的屏幕分区显示效果。
图3A示例性示出一组应用自配置第二分区中背景色的用户界面。
图3A的a示出用户界面31，该用户界面31为电子设备100外屏显示的主界面。该主界面包括第一分区和第二分区，第一分区和第二分区联合显示系统主题的背景，并且第一分区显示有应用图标，第二分区显示有电子设备的状态信息(暂时仅以时间为例示出)。
若电子设备100接收到作用于图3A的a中所示的应用A的图标上的操作，响应于该操作，电子设备则在第一分区中显示应用A的界面。若该应用A还自配置了第二分区的背景色，则电子设备100还会在第二分区中显示应用A自配置的背景色，具体如下文描述的图3A的b所示的用户界面32。
其中，应用A自配置第二分区的背景色是指，由应用A的开发商/开发人员，在开发应用A或者更新应用A时，在该应用的安装包中配置了对应的第二分区背景色，当电子设备100安装并运行该应用A后，则在第二分区中显示应用A对应的背景色。该应用A可以是第三方应用或者系统应用，本申请实施对此不作限制。
图3A的b示出用户界面32，该用户界面32为电子设备100外屏显示的界面。该界面包括第二分区和第一分区，第一分区显示应用A的界面，且该应用A的界面中大多数控件的背景为白色，第二分区则按照应用A自配置的白色作为背景色(又称第一背景色)显示。可选的，电子设备为了匹配第二分区中的背景色，会显示与该背景色存在一定对比度的电子设备的状态信息，例如显示黑色(相应的色彩值又称第一预设值，可以是饱和度为42亮度为26％色相为FFFFFF)的时间等，从而保证用户可以准确读取到电子设备的状态信息。
图3A所示的应用自配置第二分区的背景色的显示效果仅为示例，不同应用自配置的第二分区的背景色可能不同，但是，第二分区的背景与第一分区的风格相似，这里仅以应用A显示的白色为例来介绍，不应构成对本申请的限制。可选的，应用A除了自配置二分区背景色以外，还可以配置第二分区中文本的格式等，本申请实施例对此不作限制，在此暂不一一赘述。
图3B示例性示出一组电子设备预配置第二分区中背景色的用户界面。
图3B的a示出用户界面33，该用户界面33为电子设备100外屏显示的界面，该界面与前述图3A中b示出的用户界面32相同，关于对该界面的介绍可参考前文的描述，在此暂不赘述。
若电子设备100接收到用于从应用A切换至应用B的操作(又称第一操作)，响应于该操作，电子设备在第一分区中切换至显示应用B的界面，若该应用B未自配置了第二分区的背景色，且电子设备100预配置了应用B对应的第二分区的背景色，则电子设备100还会在第二分区中显示电子设备100预配置的应用B对应的背景色，具体如下文描述的图3B的b所示的用户界面34。
其中，电子设备预配置应用B对应的第二分区的背景色是指，由电子设备100的开发人员，在开发电子设备/更新电子设备系统时，为应用B配置的对应的第二分区的背景色。可选的，可以使用可扩展标示语言(Extensive Markup Language，XML)为应用B配置XML文件，在该XML文件中存储应用B对应的第二分区的背景色，后续电子设备100的开发人员可以远程更新应用B的XML文件，以实现更新应用B对应的第二分区的背景色。
图3B的b示出用户界面34，该用户界面34为电子设备100外屏显示的界面。该界面包括第二分区和第一分区，第一分区显示应用B的界面，且该界面中较大控件的背景的色彩值为A，第二分区中显示的背景色(又称第二背景色)变为在色彩值A之上叠加色彩值a后形成的色彩值。其中，应用B的界面中的各个控件可通过绘制相应的视图(View)来实现。可选的，电子设备为了匹配第二分区中的背景色，会显示与该背景色存在一定对比度的电子设备的状态信息，例如显示黑色的时间等，从而保证用户可以准确读取到电子设备的状态信息。
其中，电子设备100预配置的背景色可以包括：背景基础色即色彩值A(又称第三色彩值)，和背景叠加色即色彩值a(又称第四色彩值)；或者，电子设备100预置的背景色，为色彩值A之上叠加色彩值a后形成的最终色彩值(又称第二预设值)。其中，色彩值A可以是单一的纯色，图3B中以填充间隔均匀的斜线图案来表征色彩值A，该色彩值A与对应的应用B的界面中的色彩值相同。色彩值a可以是具有亮度渐变效果的色彩值，图3B 中以填充间隔由密到疏的横线图案来表征色彩值a，色彩值a例如是亮度渐变的白色。这样，色彩值A之上叠加色彩值a后，不仅可以保留基础的色彩值A的信息，还能够通过覆盖的亮度渐变效果，将第二分区与第一分区进行轻微的区别显示，既可以避免两个分区的割裂感，又可以帮助用户聚焦第一分区中的关键任务。可以理解的，电子设备预先配置的背景色中所包含的背景基础色可能与应用B中的色彩A完全一致，也可能与应用B中的色彩A相近似，本申请实施例对此不作限制。

基于前文介绍的UI实施例，接下来结合图5所示的屏幕分区显示方法流程，来详细介绍本申请提供的四种屏幕分区显示策略。
图5示例性示出一种屏幕分区显示方法流程。该屏幕分区显示的方法流程包括以下步骤：
S51～S52：触发第二分区中背景色板切换为与第一分区中的应用窗口相适配的背景色。
S51，检测到待在屏幕中第一分区显示的焦点窗口发生切换。
具体的，电子设备100运行屏幕时，可以在屏幕的第一分区显示应用窗口，其中，显示在最顶层的，用户可见的，且用户能够直接与之交互的窗口即为焦点窗口。以前述图3A所示的场景为例，在当屏幕的第一分区显示桌面时，则焦点窗口为桌面应用提供的窗口，当电子设备打开应用A并在屏幕的第一分区显示应用A的界面时，则焦点窗口切换为应用A的窗口。以前述图3B所示的场景为例，在当电子设备打开应用B并在屏幕的第一分区 显示应用B的界面时，则焦点窗口切换为应用B的窗口。以前述图3C所示的场景为例，在当电子设备打开应用C并在屏幕的第一分区显示应用C的界面时，则焦点窗口切换为应用C的窗口。以前述图3D所示的场景为例，在当电子设备打开应用D并在屏幕的第一分区显示应用D的界面时，则焦点窗口切换为应用D的窗口。
可选的，响应于用户切换应用界面的操作，可以触发切换焦点窗口以实现在屏幕的第一分区中显示切换后的应用界面。具体的，响应于用户切换应用界面的操作，电子设备的活动管理服务(Activity manager service，AMS)会启动新界面对应的新Activity，AMS则开始管理新Activity的运行状态和旧Activity的运行状态，当AMS通知窗口管理服务(Window manager service，WMS)新Activity切换为继续(Resumed)状态，旧Activity切换为暂停(Paused)状态，则触发WMS切换焦点窗口，包括将旧Activity对应的旧窗口设置为不可见状态，将新Activity对应的新窗口设置为可见状态，从而触发后续绘制、渲染、合成送显该新窗口，进而实现显示切换后的新界面。
可选的，这里的屏幕可以是前述图2中所示的外屏，关于该屏幕的介绍可以参考前文的描述，在此暂不赘述。
可选的，在检测待在屏幕中第一分区显示的焦点窗口发生切换前，还可以先确定是否进行屏幕分区显示，若确定屏幕分区显示，则采用图5所介绍的分区显示策略进行显示。若确定全屏显示，则按照对应的全屏显示策略进行显示，本申请实施例对全屏显示的内容不作具体限制，具体可以由待显示的桌面或其他应用而决定。例如，全屏显示的场景包括但不限于：显示桌面、天气或者其他应用程序的场景，本申请可以预置全屏显示的场景，或者也可以预置分区显示的场景等。
S52，在切换后的焦点窗口绘制完成后，获取焦点窗口对象。
具体的，在检测到焦点窗口发生切换后，电子设备会执行绘制该焦点窗口的任务，当电子设备绘制完焦点窗口后，则电子设备可以获取到绘制完成后的焦点窗口对象。
焦点窗口对象包括但不限于：应用包名、窗口标识，或者还包括：关系属性、屏幕信息属性等。其中，应用包名为该焦点窗口所属的应用的包名，窗口标识可以唯一标识该窗口，关系属性可包括如parent和top属性，分别用于返回父窗口和最顶层先辈窗口的引用，屏幕信息属性可包括screenLeft和screenTop属性，其声明了窗口相对于屏幕的位置。
可选的，当窗口所属应用自配置有该窗口对应的第二分区的背景色，则窗口对象中还额外携带相应的属性值，该属性值用于指示第二分区的背景色，本申请实施例对第二分区的属性值的具体设置形式不作限制。
S53～S54-2：策略1，采用应用自配置的色彩值作为第二分区的背景色。
S53，基于焦点窗口对象确定对应的第一应用是否配置第二分区的背景色。
具体的，电子设备100支持应用的开发者自配置该应用对应在第二分区的背景色，若开发者已经对该应用自配置第二分区的背景色，则电子设备100可以从前述S52中获取的焦点窗口对象中携带的属性值中获取到背景色。因此，电子设备可以基于焦点窗口对象确定对应的第一应用是否自配置第二分区的背景色，当确定焦点窗口对象中携带相应的属性值，则确定第一应用自配置了第二分区的背景色，进而按照对应第一应用的自配置结果来 控制第二分区的背景色(即执行后续S54-1～S54-2)；当确定焦点窗口对象中未携带相应的属性值，则确定第一应用没有自配置了第二分区的背景色，进而按照电子设备提供的预配置/智能适配的策略来控制第二分区的背景色(即执行后续S55等)。
S54-1，若确定第一应用自配置第二分区的背景色，则基于焦点窗口对象中的属性值，获取第二分区的背景色。
具体的，电子设备可以从焦点窗口对象的属性值中获取到第一应用自配置的第二分区的背景色。通常，第一应用自配置的第二分区的背景色可以与第一分区中的焦点窗口的色彩值相似或者相同，从而带给用户全屏联合显示第一应用的视觉体验。
S54-2，在屏幕的第一分区显示第一应用的焦点窗口，在屏幕的第二分区显示第一应用配置的背景色。
具体的，在电子设备切换焦点窗口后，可以在第一分区中显示切换后的焦点窗口，从而形成第一应用的用户界面，以及在电子设备获取到第一应用自配置的第二分区的背景色后，还可以在第二分区中显示相应的背景色。
可选的，电子设备可以同时在第一分区中显示焦点窗口，以及在第二分区显示与之对应的背景色，或者，电子设备还可以先在第一分区中显示焦点窗口，后再第二分区中显示与之对应的背景色，但是用户视觉上感知不到两者之间的时延，相当于同时看到两个分区中的内容切换。本申请实施例对此不作限制，具体取决于电子设备控制屏幕送显的策略，屏幕可以仅支持同时刷新第一分区和第二分区，也可以支持分别刷新第一分区和第二分区。
关于S54-2中涉及的分区显示效果还可以参考前文UI实施例中对图3A的描述，在此暂不赘述。
S55～S56-2：策略2，采用电子设备预配置的色彩值作为第二分区的背景色。
S55，若确定第一应用未自配置第二分区的背景色，则确定第一应用是否属于电子设备的第一白名单中。
具体的，电子设备可以预先为第一白名单中的应用配置默认的第二分区的背景色，因此，电子设备可以检测该第一应用是否属于第一白名单中，若属于，则采用电子设备预置的色彩值作为第二分区的背景色来显示(即执行后续的S56-1～S56-2)；若不属于，则采用智能提取的色彩值最为第二分区的背景色来显示(即执行后续的S57等)。
其中，第一白名单中不同应用对应的第二分区的背景色可以相同或者不同，同一应用可以对应一个背景色，或者同一应用可以根据不同窗口等级分别对应不同的背景色，例如应用的一级界面的窗口、二级界面的窗口等等可分别配置不同的背景色本申请实施例对此不作限制。
S56-1，若第一应用属于第一白名单，则从第一应用的配置文件中获取对应的第二分区的背景色。
具体的，在确定第一应用属于第一白名单后，则从第一应用的配置文件中获取电子设备预先配置的第二分区的背景色。当电子设备仅对第一应用配置一个背景色时，无论焦点窗口为第一应用的哪一个窗口均可以使用该一个背景色，当电子设备对第一应用配置有多个背景色时，则还以基于当前焦点窗口对应的第一应用的界面等级来获取相应的背景色。 后者主要考虑到，同一个应用不同等级的界面的颜色不同，因此电子设备可以预先根据不同等级界面来配置与之相同或者相近的背景色。
可选的，第一应用的配置文件中存储的第二分区的背景色可以是单一色彩(即本申请实施例中所述的背景基础色)，也可以是由多种色彩组合而成的色彩(即本申请实施例中所述的背景基础色结合背景叠加色得到色彩)，其中，背景基础色可以是色调-饱和度-亮度(Hue-Saturation-Brightness，HSB)色彩空间下的单一色彩，例如粉色、黄色、绿色或者红色等，背景叠加色可以是HSB色彩空间下亮度渐变的白色，该亮度渐变的白色叠加在背景基础色之上，既不会完全覆盖原始的背景基础色，又可以通过亮度渐变的效果区分第一分区和第二分区，使得用户聚焦第一分区中的主要任务，本申请实施例对此不作限制。
S56-2，在屏幕的第一分区显示第一应用的焦点窗口，在屏幕的第二分区显示电子设备配置的背景色。
具体的，在电子设备切换焦点窗口后，可以在第一分区中显示切换后的焦点窗口，从而形成第一应用的用户界面，以及在电子设备获取到电子设备预配置的第一应用对应的第二分区的背景色后，还可以在第二分区中显示相应的背景色。
可选的，电子设备可以同时在第一分区中显示焦点窗口，以及在第二分区显示与之对应的背景色，或者，电子设备还可以先在第一分区中显示焦点窗口，后再第二分区中显示与之对应的背景色，但是用户视觉上感知不到两者之间的时延，相当于同时看到两个分区中的内容切换。本申请实施例对此不作限制，具体取决于电子设备控制屏幕送显的策略，屏幕可以仅支持同时刷新第一分区和第二分区，也可以支持分别刷新第一分区和第二分区。
关于S56-2中涉及的分区显示效果还可以参考前文UI实施例中对图3B的描述，在此暂不赘述。
S57～S58-4：策略3，采用电子设备智能提取的背景基础色结合电子设备预置的背景叠加色作为第二分区的背景色。
S57，若第一应用不属于第一白名单，则确定第一应用是否属于电子设备的第二白名单中。
具体的，电子设备可以预先为第二白名单中的应用配置第二分区的背景叠加色，该背景叠加色用于叠加在从焦点窗口中提取的背景基础色，作为第二分区最终的背景色。因此，电子设备可以检测该第一应用是否属于第二白名单中，若属于，则采用电子设备预置的背景叠加色作为第二分区的背景色的叠加层来显示(即执行后续的S58-1～S58-4)；若不属于，则采用智能提取的背景基础色最为第二分区的背景色来显示(即执行后续的S59-1～S59-2)。
其中，第二白名单中不同应用对应的第二分区的背景叠加色可以相同或者不同，同一应用可以对应一个背景叠加色，或者同一应用可以根据不同窗口等级分别对应不同的背景叠加色，例如应用的一级界面的窗口、二级界面的窗口等等可分别配置不同的背景叠加色本申请实施例对此不作限制。
S58-1，若第一应用属于第二白名单，则从第一应用的配置文件中获取对应的第二分区的背景叠加色。
具体的，在确定第一应用属于第二白名单后，则从第一应用的配置文件中获取电子设 备预先配置的第二分区的背景叠加色。当电子设备仅对第一应用配置一个背景叠加色时，无论焦点窗口为第一应用的哪一个窗口均可以使用该一个背景叠加色，当电子设备对第一应用配置有多个背景叠加色时，则还以基于当前焦点窗口对应的第一应用的界面等级来获取相应的背景叠加色。
可选的，电子设备预配置的每个应用对应的第二分区的背景叠加色均为亮度渐变的白色或者亮度渐变的其他色彩值等，该亮度渐变色叠加在背景基础色之上，既不会完全覆盖背景基础色，又可以通过亮度渐变的效果区分第一分区和第二分区，使得用户聚焦第一分区中的主要任务，本申请实施例对此不作限制。
S58-2，基于焦点窗口对象从对应焦点窗口的View中提取对应的第二分区的背景基础色。
具体的，在确定第一应用属于第二白名单后，除了从第一应用的配置文件中获取背景叠加色外，还会基于焦点窗口对象从对应焦点窗口中的View中提取背景基础色，本申请实施例对该两个步骤的先后顺序不作限制。
其中，焦点窗口对象中携带窗口标识，绘制而成的焦点窗口由各个View组成，View可以是各类控件、文本等等，电子设备可以基于该窗口标识来提取焦点窗口的View的颜色，以作为第二分区的背景基础色。
可选的，焦点窗口的View可能包括很多，不同View的颜色可能不完全一致，因此，电子设备可以选取焦点窗口中View满足以下条件：层数为顶部10层以内，用户可见的，所占面积大于根视图(DecorView)面积的80％，背景色不为空，最后将与View的背景色相同或者相近的色彩值作为最终的背景基础色。
可选的，一种选取与View的背景色相近的色彩值作为最终的背景基础色的方法包括：先将View的背景色的实际色彩值转化为HSB色彩空间，然后对该色HSB色彩空间中亮度B通道的数值做调，例如：亮度B通道的数值由范围0％～100％亮度B划分为多个数值，以划分为50％和100％，然后将实际亮度B属于0％～50％的设置为50％，将实际亮度B属于50％～100％的设置为100％。可选的，还可以将亮度B划分为更多段来调整，本申请实施例对此不作限制。或者，还可以对该HSB色彩空间中饱和度S通道的数值做调整，例如将实际饱和度S大于40的数值均设置为上限值40。又或者，还可以对该HSB色彩空间中色相H通道的数值做调整等，本申请实施例对选取与View实际背景色相近的色彩值作为背景基础色的方法不作具体限制。
S58-3，将背景基础色和背景叠加色叠加后得到第二分区的背景色。
前述在S58-2中获取到背景基础色后和在S58-1中获取到背景叠加色后，可以将背景叠加色覆盖在背景基础色后获得的最终色彩作为第二分区的背景色。通过该方式获取的背景色既保证与第一分区中色彩值相近似，提升用户的视觉体验，又可以保证第二分区中背景色亮度和饱和度适中，减少对第一分区中关键内容的影响。
可选的，电子设备还会基于最终获取的第二分区的背景色来确定第二分区中显示的电子设备状态信息的色彩值，保证两者之间存在一定的对比度，这样可以保证第二分区中显示内容的可读性。
S58-4，在屏幕的第一分区显示第一应用的焦点窗口，在屏幕的第二分区显示电子设备 配置的背景色。
具体的，在电子设备切换焦点窗口后，可以在第一分区中显示切换后的焦点窗口，从而形成第一应用的用户界面，以及在电子设备获取到电子设备预配置的第一应用对应的第二分区的背景色后，还可以在第二分区中显示相应的背景色。
可选的，电子设备可以同时在第一分区中显示焦点窗口，以及在第二分区显示与之对应的背景色，或者，电子设备还可以先在第一分区中显示焦点窗口，后再第二分区中显示与之对应的背景色，但是用户视觉上感知不到两者之间的时延，相当于同时看到两个分区中的内容切换。本申请实施例对此不作限制，具体取决于电子设备控制屏幕送显的策略，屏幕可以仅支持同时刷新第一分区和第二分区，也可以支持分别刷新第一分区和第二分区。
关于S58-4中涉及的分区显示效果还可以参考前文UI实施例中对图3C的描述，在此暂不赘述。
S59-1～S59-2：策略4，采用电子设备智能提取的背景基础色作为第二分区的背景色。
S59-1，若第一应用不属于第二白名单，则基于焦点窗口对象从对应焦点窗口中的View，获取对应的第二分区的背景基础色。

S59-2，在屏幕的第一分区显示第一应用的焦点窗口,在屏幕的第二分区显示电子设备配置的背景色。
S59-2与前述S58-4相似，其区域别在于，S59-2中第二分区的背景色仅为电子设备提取的背景基础色，而S58-4中第二分区的背景色为电子设备提取的背景基础色结合电子设备预置的背景叠加色得到的色彩值，关于对S59-2的描述，可以参考前文对S58-4的描述，在此暂不赘述。
关于S59-2中涉及的分区显示效果还可以参考前文UI实施例中对图3D的描述，在此暂不赘述。
可以理解的是，在前述介绍的图5中所述的屏幕分区显示方法中，将四种屏幕分区显示的策略按照优先级从高到低依次为：应用自配置、电子设备预配置、电子设备预配置叠加智能提起和仅智能提起的先后顺序来依次判断满足何种条件，进而采取相应的策略来控制屏幕分区显示效果。可选的，还可以采用除图5所示的优先级顺序以外的其他优先级顺序来依次判断采用何种策略来控制屏幕分区显示效果，本申请实施例对此不作限制。
基于前述对图5所示的屏幕分区显示方法流程的介绍，接下来结合图6进一步介绍本申请涉及的屏幕分区显示方法的OS交互流程。
图6示例性示出一种屏幕分区显示方法的OS交互流程示意图。具体包括以下步骤：
该OS交互涉及的电子设备100的软件模块包括但不限于：第一应用、WMS、LetterBox、Task任务管理模块、ViewRootImpl、文件解析、View管理框架等模块，关于这些模块的详细介绍还可以参考后文对电子设备100的软件架构的介绍，在此暂不赘述。
阶段1(S61-S68)：触发获取第二分区的背景色。
S61，第一应用获取到第一操作事件。
具体的，在用户输入用于切换至第一应用的界面的第一操作后，电子设备的第一应用可以获取到第一操作事件。
可选的，本申请所述的第一应用可以是前述应用A、应用B、应用C或者应用D中的任意一个，相应的，第一操作也可以是前述图3A所示的作用于桌面中的应用A的图标上的操作，或者还可以是前述图3B所涉及的用于切换至应用B的界面的操作，或者还可以是前述图3C所涉及的用于切换至应用C的界面的操作，或者还可以是前述图3D所涉及的用于切换至应用D的界面的操作等等，本申请实施例对此不作限制。
S62，第一应用通过AMS通知WMS第一应用的第一活动被设置为Resumed状态。
具体的，在第一应用获取到前述第一操作事件后，第一应用可以通过执行onStart()方法，以启动第一应用的第一活动(Activity)，该第一活动可以是第一应用的主活动(Main Activity)或者是上次前台运行时开启的非主活动等。启动第一活动后，AMS可以管理该第一活动的生命周期，当第一活动进入Resumed状态后，AMS则会协同其他模块依次执行绘制、渲染、送显该第一活动对应的第一窗口的任务，进而实现后续显示第一窗口以形成用户可见的第一界面。其中，当第一活动进入Resumed状态时，切换至第一应用之前的其他活动会进入Paused状态，AMS还会将第一活动被设置Resumed状态的消息通知至WMS，使得WMS基于此来切换焦点窗口。
可选的，当第一应用为应用A时，AMS启动的第一应用的第一活动可以是前文介绍的图3A中用户界面32所对应的活动；当第一应用为应用B时，AMS启动的第一应用的第一活动可以是前文介绍的图3B中的用户界面34所对应的活动；当第一应用为应用C时，AMS启动的第一应用的第一活动可以是前文介绍的图3C中的用户界面36所对应的活动；当第一应用为应用D时，AMS启动的第一应用的第一活动可以是前文介绍的图3D中的用户界面38所对应的活动。
S63，WMS将第一活动的第一窗口设置为焦点窗口。
具体的，WMS在获知第一活动被设置为Resumed状态后，则表征用户想要聚焦第一活动对应的界面，因此需要将第一活动的第一窗口设置为焦点窗口，即将该第一窗口设置为可见转态，从而保证后续在顶部显示该第一窗口，进而保证后续用户可以看见送显后的该第一窗口形成的第一界面。
S64，WMS通知LetterBox刷新第二分区的背景色。
具体的，在WMS将第一窗口设置为焦点窗口之后，由于第一窗口后续被送至第一分区中显示，因此WMS还需要随着第一分区的窗口变化来调整第二分区的背景色，具体的，WMS可以通知LetterBox来刷新第二分区的背景色。
其中，LetterBox提供了一种应用显示模式的刷新机制。具体的，一些应用程序需要在不同尺寸的设备上保持界面的一致性和功能性，但是一些设备(例如可折叠设备)具有与传统设备不同的屏幕尺寸和宽高比，因此当应用的界面设计仅针对传统的标准尺寸的屏幕时，就会出现显示兼容性问题。为了解决这一问题，LetterBox可以通过填充屏幕中部分区域(例如第二分区)来确保应用界面不会因设备屏幕的差异而变形或被拉伸。
S65，LetterBox向Task任务管理模块注册第一窗口的绘制完成的监听服务。
