Description

显示方法及电子设备
本申请要求于2021年05月29日提交国家知识产权局、申请号为202110595998.4、发明名称为“显示方法及电子设备”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
本申请实施例涉及终端技术领域，尤其涉及一种显示方法及电子设备。
背景技术
应用程序启动过程中，电子设备会按照预先设定的动画效果，显示应用程序图标以及应用程序窗口，从而为用户提供更好的启动应用程序的视觉效果。
比如，电子设备检测到用户点击应用程序图标的操作后，桌面应用进程显示应用程序图标的动效，窗口管理服务绘制应用程序窗口并调用系统服务进程在应用程序图标动效之后显示应用程序窗口动效，完成应用程序启动动效的显示过程。
基于此，若桌面应用进程显示的动效与系统服务进程显示的动效衔接异常，则会导致应用程序启动动效的显示过程中出现卡顿异常，影响用户使用体验。
发明内容
为了解决上述的技术问题，本申请提供了一种显示方法及电子设备。本申请提供的技术方案，窗口管理服务创建用于显示应用图标动效的图层，通过窗口管理服务控制应用图标动效以及窗口动效，从而保证应用启动动效的显示效果，避免出现卡顿异常，提升用户使用体验。
为了实现上述的技术目的，本申请实施例提供了如下技术方案：
第一方面，提供一种显示方法，应用于电子设备。该方法包括：接收来自用户的应用启动指令。响应于应用启动指令，创建应用的图标对应的第一图层；根据第一图层和应用的第一图标数据，显示应用的图标启动动效；获取应用对应的第一窗口信息，显示应用的窗口启动动效。其中，第一图层是应用的窗口对应的图层；或者，第一窗口信息包括应用的窗口对应的第二图层，第一图层位于第二图层之下。
其中，用户的启动指令用于指示电子设备启动对应的应用，例如可以包括在显示屏上点击该应用图标的操作。
在一些实施例中，窗口管理服务创建专门用于显示应用图标动效的图层，从而实现电子设备通过窗口管理服务控制应用图标动效。而现有技术中，桌面控制应用图标动效，窗口管理服务不会创建应用图标对应的图层。基于此，若在应用启动动效过程中，对应用图标图层内的数据进行获取，则可以在该应用图标对应的图层内，获取到应用图标数据。
此外，应用启动动效应为先显示应用图标动效，再显示应用窗口动效，因此可以创建应用图标对应的图层，置于应用窗口对应的图层之下，从而在显示应用窗口对应的图层时能够将应用图标对应的图层覆盖，实现应用启动动效的切换衔接。
在另一些实施例中，窗口管理服务没有为应用图标建立对应的图层，而是复用应 用窗口对应的图层。但是，窗口管理服务同样能够获取到应用图标对应的位图，将该位图填入应用窗口对应的图层，此时窗口管理服务还未获取到应用窗口内容数据(即还未开始显示应用窗口动效)，因此，在应用窗口图层内仅包含填入的应用图标对应的位图，实现由窗口管理服务控制应用图标动效。相比于现有技术，桌面控制应用图标动效，窗口管理服务创建的应用窗口图层内不会包含应用图标数据。基于此，若对应用图标动效显示过程中的应用窗口图层内的数据进行获取，则可以获取到应用图标数据。
这样，电子设备在接收到用户的应用启动指令后，能够通过窗口管理服务(WMS)创建用于显示应用图标动效的图层，通过窗口管理服务生成应用图标对应的图层数据以及通过窗口管理服务生成应用窗口对应的图层数据，进而实现利用窗口管理服务创建应用图标动效以及应用窗口动效，实现包含应用图标动效和应用窗口动效的应用启动动效的显示。进而由窗口管理服务创建应用启动动效，能够避免出现由于桌面创建应用图标动效以及窗口管理服务创建应用窗口动效导致的动效衔接异常，造成的闪现、错位等异常卡顿问题，提升用户使用体验。
根据第一方面，或者以上第一方面的任意一种实现方式，第一窗口信息还包括应用的窗口对应的第一窗口内容，第一窗口内容包括如下任一项或几项：应用对应的主界面内容、应用对应的后台缓存界面内容、应用对应的启动窗口内容。
在一些实施例中，电子设备中的窗口管理服务接收应用发送的第一窗口内容，该第一窗口内容可以为应用主界面显示内容数据、或者后台应用界面显示内容数据、或者启动窗口图片数据，对应于启动不同类型的应用，应用窗口内容数据类型不同。
这样，对于在接收到应用启动指令之前未启动的应用，后台应用，配置有启动窗口机制的应用，未配置启动窗口机制的应用，均能够利用窗口管理服务实现创建应用图标动效以及应用窗口动效，提升应用启动动效的流畅性。
根据第一方面，或者以上第一方面的任意一种实现方式，当第一图层在第二图层之下时，获取应用对应的第一窗口信息，显示应用的窗口启动动效，包括：获取应用对应的第一窗口信息；根据第一窗口信息和第一图标数据，显示应用的窗口启动动效。
在一些实施中，当第一图层为应用图标对应的图层，位于应用窗口对应的图层之下时，窗口管理服务在接收到应用图标数据(如应用图标对应的位图)后，根据应用图标对应的位图确定应用图标对应的图标信息，利用图标信息对应用窗口内容数据进行裁剪。比如，裁剪应用图标透明区域，确定应用窗口对应的图层数据，从而使得在显示应用图标动效和应用窗口动效衔接过程中，实现应用图标的淡出显示效果。进而能够为用户提供更好的显示效果，提升用户使用体验。
根据第一方面，或者以上第一方面的任意一种实现方式，当第一图层在第二图层之下时，方法还包括：确定显示屏分辨率变化，删除第一图层。
在一些实施例中，窗口管理服务在确定电子设备满足预设条件时，删除创建的应用图标对应的图层。其中，预设条件例如包括电子设备分辨率变化，从而避免由于分辨率变化导致仍利用原应用图标图层创建应用图标动效导致的应用图标动效显示异常。
例如，电子设备应用的分辨率为分辨率1时，窗口管理服务创建应用图标对应的图层A并保存该图层A，用于显示应用图标动效。后续，若电子设备应用的分辨率为 分辨率1的过程中，检测到其他启动应用的操作，窗口管理服务仍利用图层A生成对应的应用图标的图层数据。并且，在确定电子设备应用的分辨率变化后，如分辨率由分辨率1变化为分辨率2，窗口管理服务删除图层A。在检测到启动应用的操作后，窗口管理服务创建新图层如图层B，利用图层B生成对应的应用图标的图层数据。
根据第一方面，或者以上第一方面的任意一种实现方式，当第一图层在第二图层之下时，方法还包括：接收来自用户的应用关闭指令。响应于应用关闭指令，获取应用对应的第二窗口信息以及应用对应的第二图标数据；根据第二窗口信息和第二图标数据，显示应用的窗口退出动效；确定是否存在第一图层；若存在，则根据第一图层和第二图标数据，显示应用的图标退出动效；若不存在，则创建第一图层，根据第一图层和第二图标数据，显示应用的图标退出动效。
在一些实施例中，在应用启动过程中，窗口管理服务会建立应用图标对应的图层，并且在电子设备未满足预设条件的情况下，不会删除该图层。因此，窗口管理服务在接收到应用图标对应的位图(即第二图标数据)后，需要确定是否存在应用图标对应的图层。若存在，则直接利用该图层生成应用图标对应的图层数据；若不存在，则需要先创建应用图标对应的图层，再生成应用图标对应的图层数据。
如此，响应于用户关闭应用的操作，电子设备能够通过窗口管理服务创建应用窗口动效，并且通过窗口管理服务基于获得的应用图标对应的位图创建应用图标动效，实现包含应用窗口动效和应用图标动效的用于关闭动效的显示。进而由窗口管理服务创建应用关闭动效，能够避免出现由于窗口管理服务创建应用窗口动效以及桌面创建应用图标动效导致的动效衔接异常，造成的闪现、错位等异常卡顿问题，提升用户使用体验。
根据第一方面，或者以上第一方面的任意一种实现方式，第二窗口信息包括第二图层和应用对应的第二窗口内容，第二窗口内容包括电子设备在接收到应用关闭指令时应用的显示界面内容；第二图标数据包括第一图标数据和/或应用的图标对应的文件夹数据。
在一些实施例中，部分应用程序图标在电子设备桌面文件夹内显示，那么对于这部分应用的应用关闭动效中的应用图标动效还应包括应用图标对应的文件夹的文件夹动效。
这样，电子设备在显示应用关闭动效的过程中，能够根据应用类型，为用户提供适应的应用关闭动效，提升用户使用体验。
根据第一方面，或者以上第一方面的任意一种实现方式，当第一图层是所述应用的窗口对应的图层时，在获取应用对应的第一窗口信息，显示应用的窗口启动动效之前，方法还包括：删除第一图层内的第一图标数据。
根据第一方面，或者以上第一方面的任意一种实现方式，获取应用对应的第一窗口信息，显示应用的窗口启动动效，包括：获取应用对应的第一窗口信息；根据第一窗口信息，显示应用的窗口启动动效。
在一些实施例中，窗口管理服务获得的应用窗口信息例如包括接收到的应用程序发送的应用窗口内容数据，窗口管理服务在接收到应用窗口内容数据后，确定需要显示应用窗口动效，但当前应用窗口图层被应用图标对应的位图(即第一图标数据)占 用，因此需要删除应用图标对应的位图。之后，将应用窗口内容数据填入已删除应用图标对应的位图的应用窗口图层中，获得应用窗口对应的图层数据。
根据第一方面，或者以上第一方面的任意一种实现方式，当第一图层是所述应用的窗口对应的图层时，方法还包括：接收来自用户的应用关闭指令。响应于应用关闭指令，获取应用对应的第二窗口信息以及应用对应的第二图标数据；根据第二窗口信息，显示应用的窗口退出动效；根据第一图层和第二图标数据，显示应用的图标退出动效。
这样，响应于用户关闭应用的操作，电子设备能够通过窗口管理服务创建应用窗口动效，并且通过窗口管理服务基于获得的应用图标对应的位图创建应用图标动效，实现包含应用窗口动效和应用图标动效的用于关闭动效的显示。进而由窗口管理服务创建应用关闭动效，能够避免出现由于窗口管理服务创建应用窗口动效以及桌面创建应用图标动效导致的动效衔接异常，造成的闪现、错位等异常卡顿问题，提升用户使用体验。
第二方面，提供一种显示方法，应用于电子设备。该方法包括：接收来自用户的应用启动指令。响应于应用启动指令，电子设备通过窗口管理服务创建应用的图标对应的第一图层。电子设备通过窗口管理服务根据第一图层和应用的第一图标数据确定应用的图标对应的图层数据，显示应用的图标启动动效。电子设备通过窗口管理服务获取应用对应的第一窗口信息，根据第一窗口信息确定应用的窗口对应的图层数据，显示应用的窗口启动动效。其中，第一图层是应用的窗口对应的图层；或者第一窗口信息包括应用的窗口对应的第二图层，第一图层位于第二图层之下。
根据第二方面，当第一图层在第二图层之下时，该方法还包括：接收来自用户的应用关闭指令。响应于应用关闭指令，电子设备通过窗口管理服务获取应用对应的第二窗口信息以及应用对应的第二图标数据。电子设备通过窗口管理服务根据第二窗口信息和第二图标数据确定应用的窗口对应的图层数据，显示应用的窗口退出动效。电子设备通过窗口管理服务根据第一图层和第二图标数据确定应用的图标对应的图层数据，显示应用的图标退出动效。
根据第二方面，或者以上第二方面的任意一种实现方式，当第一图层是应用的窗口对应的图层时，该方法还包括：接收来自用户的应用关闭指令。响应于应用关闭指令，电子设备通过窗口管理服务获取应用对应的第二窗口信息以及应用对应的第二图标数据。电子设备通过窗口管理服务根据第二窗口信息确定应用的窗口对应的图层数据，显示应用的窗口退出动效。电子设备通过窗口管理服务根据第一图层和第二图标数据确定应用的图标对应的图层数据，显示应用的图标退出动效。
第二方面以及第二方面中任意一种实现方式所对应的技术效果，可参见上述第一方面及第一方面中任意一种实现方式所对应的技术效果，此处不再赘述。

具体实施方式
下面结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。其中，在本申请实施例的描述中，以下实施例中所使用的术语只是为了描述特定实施例的目的，而并非旨在作为对本申请的限制。如在本申请的说明书和所附权利要求书中所使用的那样，单数表达形式“一个”、“一种”、“所述”、“上述”、“该”和“这一”旨在包括例如“一个或多个”这种表达形式，除非其上下文中明确地有相反指示。还应当理解，在本申请以下各实施例中，“至少一个”、“一个或多个”是指一个或两个以上(包含两个)。
在本说明书中描述的参考“一个实施例”或“一些实施例”等意味着在本申请的一个或多个实施例中包括结合该实施例描述的特定特征、结构或特点。由此，在本说明书中的不同之处出现的语句“在一个实施例中”、“在一些实施例中”、“在其他一些实施例中”、“在另外一些实施例中”等不是必然都参考相同的实施例，而是意味着“一个或多 个但不是所有的实施例”，除非是以其他方式另外特别强调。术语“包括”、“包含”、“具有”及它们的变形都意味着“包括但不限于”，除非是以其他方式另外特别强调。术语“连接”包括直接连接和间接连接，除非另外说明。“第一”、“第二”仅用于描述目的，而不能理解为指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。
在本申请实施例中，“示例性地”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性地”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性地”或者“例如”等词旨在以具体方式呈现相关概念。
在一些场景中，电子设备中预置的应用启动动效包含两部分动效元素，一部分为应用图标(Icon)动效，另一部分为应用窗口(window)动效。电子设备在检测到用户启动应用程序的操作后，调用桌面进程执行显示应用图标动效，之后调用系统服务(SystemServer)进程执行显示应用窗口动效，由于桌面进程和系统服务进程之间的衔接问题，可能导致应用图标动效和应用窗口动效之间出现衔接问题，造成应用启动过程中应用启动动效卡顿导致的图像闪现、图像错位等异常，影响用户使用体验。
示例性的，如图1中(a)所示界面101，电子设备检测到用户点击图库图标11的操作后，桌面调用桌面进程显示应用图标动效，如将图标放大显示。如图1中(b)所示界面102，附图标记12指示的图标为图标放大动效过程中的某一时刻的图标显示效果。之后，窗口管理服务(window manager service，WMS)调用系统服务进程显示应用窗口(即待显示的第一个界面的窗口)动效，如将应用窗口放大显示。如图1中(c)所示界面103，附图标记13指示的应用窗口为应用窗口动效过程中某一时刻的应用窗口显示效果。电子设备完成应用窗口动效的显示后，显示如图1中(d)所示界面104，即全屏显示图库窗口，完成显示应用启动动效，完成图库应用的启动。
可以看出，在上述图1所示场景中，界面102和界面103对应的动效分别由桌面和WMS控制，导致两个阶段的动效衔接效果较差。在界面102和界面103切换显示过程中，易出现闪现、错位异常。
基于此，本申请实施例提供一种显示方法，在检测到应用启动操作后，WMS能够获得应用图标数据，控制应用图标动效以及应用窗口动效，由单一模块执行显示应用启动动效，保证应用启动动效显示的流畅性，提升用户使用体验。
在一些实施例中，电子设备中的部分或全部应用配置有启动窗口(Starting Window)机制。其中，Starting Window机制例如包括在电子设备中为应用程序预置一张图片，在待显示的应用程序第一个显示界面绘制完成之前，显示该预置图片动效。那么，应用启动动效中的窗口动效可以为待显示的应用的第一显示界面的动效，也可以为Starting Window动效。
示例性的，假设智慧生活应用采用Starting Window机制，配置有启动动效对应的Starting Window图片，如图2中(a)所示界面201，电子设备检测到用户点击智慧生活图标21的操作后，确定启动智慧生活应用，则绘制对应的第一个显示界面(即显示智慧生活主界面)的窗口内容，并开始显示启动动效。启动动效包含如图2中(b)所示界面202中附图标记22指示的图标放大过程中某一时刻的图标动效，以及如图2中(c)所示界面203中附图标记23指示的预置图片放大过程中某一时刻的预置图片 对应的应用窗口动效。之后，如图2中(d)所示界面204，电子设备显示预置图片直至第一个显示界面的窗口内容绘制完成，显示如图2中(e)所示界面205，即显示智慧生活主界面，完成智慧生活应用的启动。那么在本申请实施例提供的显示方法中，WMS应控制界面202所示的应用图标动效显示、界面203所示的Starting Window动效显示以及界面204所示的Starting Window动效显示。
在一些实施例中，待启动的应用程序还可以为后台应用。假设在上述图1所示场景中，电子设备在检测到点击图库图标11的操作之前未启动图库应用，则在检测到点击图库图标11的操作后，电子设备打开图库应用，图库应用成为前台应用。假设在上述图1所示场景中，电子设备在检测到点击图库图标11的操作之前已启动图库应用，则在检测到点击图库图标11的操作后，电子设备打开图库应用，将图库应用由后台应用转变为前台应用。
可选的，根据应用程序是否可以直接与用户交互，可以将应用程序分为包括：前台应用、后台应用。前台应用和后台应用为对应用程序运行状态的描述，其中，前台应用为用户放置在前台的、可以直接交互的应用程序，后台应用为用户放置在后台的、不可以直接交互的应用程序。在本申请的实施例中，可以根据应用程序是否直接可见，可以确定该应用是前台应用或后台应用。具体的，当应用程序可见时为前台应用，当应用程序不可见时为后台应用。例如，当电子设备的屏幕上显示应用的界面时，该应用为前台应用；当电子设备的屏幕上没有显示应用的界面时，该应用为后台应用。其中，应用的界面不包括操作系统的顶部状态栏、通知栏。
也就是说，电子设备检测到的用户启动应用的操作可以为启动未启动过的应用的操作，也可以为启动后台应用的操作，WMS确定绘制对应的应用窗口数据以及控制对应的应用窗口动效。
在一些实施例中，电子设备在检测到关闭应用程序的操作后，显示应用关闭动效。同样的，在应用关闭动效过程中，WMS能够获得桌面发送的图标数据，从而由WMS控制显示应用窗口动效以及应用图标动效，避免出现由于桌面控制应用图标动效导致的应用关闭动效卡顿异常，影响用户使用体验。

示例性地，图5为本申请实施例提供的一种显示方法示意图。该方法可以应用于电子设备，如图5所示，该方法可以包括S501-S503：
S501、检测到应用启动操作或应用关闭操作。若检测到应用启动操作，则执行S502；若检测到应用关闭操作，则执行S503。
其中，应用启动操作例如包括用户对电子设备显示屏上显示的应用图标的点击操作、语音启动应用程序的操作等。应用关闭操作例如包括点击应用界面显示的预设控件(如关闭控件、返回控件等)的操作、在显示屏上的预设手势操作(如上滑返回桌面的操作)等。可选的，电子设备检测到应用关闭操作后，可以将前台应用转换为后台应用。
在一些实施例中，电子设备检测到应用启动操作后，则通过桌面进程向系统服务进程发送活动启动(StartActivity)消息，以触发系统服务进程创建相应的应用启动动效对应的图层，用于显示相应的动效。或者，电子设备检测到应用关闭操作后，则通过桌面进程向系统服务进程发送活动关闭(StopActivity)消息或活动暂停(PauseActivity)消息，以触发系统服务进程创建相应的应用关闭动效对应的图层，用于显示相应的动效。可选的，应用启动动效或应用关闭动效例如包含两部分动效元素。比如，应用启动动效例如包括应用图标放大淡出动效，之后衔接应用窗口放大淡入动效；应用关闭动效例如包括应用窗口的缩小淡出动效，之后衔接应用图标的缩小淡入动效。
如下通过S502详细介绍应用启动动效的实现方式，以及通过S503详细介绍应用关闭动效的实现方式。
S502、显示应用启动动效。
在一些实施例中，电子设备检测到应用启动操作后，则通过桌面创建该应用对应的活动(activity)，并调用WMS创建应用图标动效以及应用窗口动效，实现显示应用启动动效。其中，活动(activity)是Android操作系统的基本组件之一，可以用于在应用程序中为用户提供可交互的界面或视图。其中，一个应用程序可以有多个活动，应用通过任务栈装载活动，其中任务栈顶端的活动为用户可以直接交互的活动。活动本身具有生命周期，可以通过操作系统提供的活动管理服务(activity manager service，AMS)去监控当前正在运行的应用程序的活动的生命周期，例如电子设备通过AMS确定活动的开始状态和暂停状态等。例如，桌面建立应用对应的活动后，由AMS监控该应用对应的活动，在应用退出后，暂停或停止该应用对应的活动。
可选的，图6为本申请实施例提供的显示方法中，显示应用启动动效步骤的第一种实施方式的具体流程图，S502可以具体实现为如图6所示的S601-S608中任意一个或多个步骤的组合。
S601、响应于应用启动操作，桌面确定应用图标对应的位图(bitmap)。
在一些实施例中，如上述S501所述，桌面检测到应用启动操作，如检测到用户点击应用图标的操作后，获取应用图标信息，例如包括应用图标的位置、大小、形状、图标中包含的透明区域尺寸等信息，确定应用图标对应的bitmap。其中，应用图标可以为单层图标，也可以为双层图标或多层图标。bitmap也可以描述为栅格图(raster graphics)或点阵图，是使用像素阵列(Pixel-array/Dot-matrix点阵)来表示的图像。
S602、桌面向WMS发送应用图标对应的位图。
在一些实施例中，桌面在确定应用图标对应的bitmap后，将该应用图标对应的bitmap发送至WMS，用于指示WMS生成bitmap对应的图层。可选的，桌面通过调用桌面进程与WMS调用的系统服务进程通过进程间通信(inter-process communication，IPC)的方式实现信息的交互。例如，桌面进程通过binder IPC方式向系统服务进程发送应用图标对应的位图。相应的，WMS接收桌面发送的应用图标对应的bitmap。
S603、WMS创建应用图标对应的图层，根据应用图标对应的位图和应用图标对应的图层，确定应用图标对应的图层数据。
在一些实施例中，如上所述应用启动动效应为先显示应用图标动效，再显示应用窗口动效，因此可以创建应用图标对应的图层，置于应用窗口对应的图层之下，从而在显示应用窗口对应的图层时能够将应用图标对应的图层覆盖，实现应用启动动效的切换衔接。
示例性的，WMS创建缓冲图层(buffer layer)1(即应用图标对应的图层)，将buffer layer 1挂载到当前绘制的用于动效显示的多个图层中的最底层。其中，用于动效显示的多个图层包括应用窗口图层。之后，将接收到的应用图标对应的bitmap填充进buffer layer 1，生成应用图标对应的图层数据，用于显示应用图标动效。
如此，WMS创建专门用于显示应用图标动效的图层，从而实现电子设备通过WMS控制应用图标动效。而现有技术中，桌面控制应用图标动效，WMS不会创建应用图标 对应的图层。基于此，若在应用启动动效过程中，对应用图标图层内的数据进行获取，则可以在该应用图标对应的图层内，获取到应用图标数据。
需要说明的是，用于动效显示的多个图层包含在动效显示过程中其他控件数据和/或布局数据对应的图层，将多个图层合成后电子设备才能够显示用户可见的动效。其中，对于用于动效显示的多个图层可以参考现有技术，本申请实施例对此不做限制。
在一些实施例中，WMS在确定电子设备满足预设条件时，删除创建的应用图标对应的图层。其中，预设条件例如包括电子设备分辨率变化，从而避免由于分辨率变化导致仍利用原应用图标图层创建应用图标动效导致的应用图标动效显示异常。
例如，电子设备应用的分辨率为分辨率1时，WMS创建应用图标对应的图层A并保存该图层A，用于显示应用图标动效。后续，若电子设备应用的分辨率为分辨率1的过程中，检测到其他启动应用的操作，WMS仍利用图层A生成对应的应用图标的图层数据。并且，在确定电子设备应用的分辨率变化后，如分辨率由分辨率1变化为分辨率2，WMS删除图层A。在检测到启动应用的操作后，WMS创建新图层如图层B，利用图层B生成对应的应用图标的图层数据。
S604、WMS向SurfaceFlinger发送应用图标对应的图层数据。
在一些实施例中，WMS在确定应用图标对应的图层数据后，将确定的图层数据发送至SurfaceFlinger进行合成，以获得用户可见的图像帧。相应的，SurfaceFlinger接收应用图标对应的图层数据。
S605、SurfaceFlinger合成应用图标对应的图层数据，以显示应用图标动效。
在一些实施例中，SurfaceFlinger接收到应用图标对应的图层数据后，调用合成线程对接收的应用图标对应的图层数据进行图层合成得到对应的图像帧，电子设备利用液晶显示面板(liquid crystal display，LCD)驱动可接收合成的图像帧，由LCD显示合成的图像帧。LCD显示图像帧后，LCD显示的图像可被人眼感知，以实现显示应用图标动效。
示例性的，如图7中(a)所示界面701，电子设备检测到用户点击图库应用图标71的操作后，WMS获取图库应用图标对应的bitmap，创建对应的图层数据，合成图层数据后显示图库应用图标对应的动效。如图7中(b)所示界面702中附图标记72指示的放大后的图标为应用图标动效中某一时刻的应用图标的显示效果。
需要说明的是，在上述步骤中以非后台应用状态且未配置Starting Window机制的应用为例对本申请实施例的应用启动效果进行说明。可以理解的是，本申请实施例提供的方法可以应用于未启动的应用启动过程、后台应用点击应用图标的应用启动过程、配置Starting Window机制的应用的启动过程、未配置Starting Window机制的应用的启动过程等多种类型的应用的启动过程，应不局限于上述示例场景，对此下文不再进行说明。
S606、WMS获取应用窗口信息，根据应用窗口信息和应用图标对应的位图，确定应用窗口对应的图层数据。
在一些实施例中，应用窗口信息例如包括应用窗口对应的图层以及接收到的应用程序发送的应用窗口内容数据。WMS根据应用图标对应的bitmap确定应用图标对应的图标信息，利用图标信息对应用窗口内容数据进行裁剪。比如，裁剪应用图标透明 区域，确定应用窗口对应的图层数据，从而使得在显示应用图标动效和应用窗口动效衔接过程中，实现应用图标的淡出显示效果。
示例性的，如图7中(c)所示界面703，界面705用于显示的应用窗口动效。其中，如S603所述，应用图标对应的buffer layer 1位于应用窗口对应的图层(如buffer layer 2)之下，因此在WMS根据应用图标对应的位图对窗口内容数据进行裁剪后，能获得过渡的显示效果，如用户透过附图标记73指示的应用窗口内容能够看到附图标记74指示的应用图标内容。并且由于buffer layer 2覆盖buffer layer 1，因此在应用窗口动效显示过程中，应用窗口内容能够完全覆盖应用图标内容，实现应用图标的淡出显示效果以及应用窗口的淡入显示效果。并且，由于界面702上显示的动效过渡到界面703上显示的动效过程均为WMS创建，因此不会出现卡顿异常，提升用户使用体验。
需要说明的是，应用程序发送的应用窗口内容数据可以为应用主界面显示内容数据、或者后台应用界面显示内容数据、或者Starting Window图片数据，对应于启动不同类型的应用，应用窗口内容数据类型不同。
S607、WMS向SurfaceFlinger发送应用窗口对应的图层数据。
在一些实施例中，WMS在确定应用窗口对应的图层数据后，向SurfaceFlinger发送应用窗口对应的图层数据。相应的，SurfaceFlinger接收应用窗口对应的图层数据。
S608、SurfaceFlinger合成应用窗口对应的图层数据，以显示应用窗口动效。
在一些实施例中，SurfaceFlinger接收到应用窗口对应的图层数据后，调用合成线程对接收的应用窗口对应的图层数据进行图层合成得到对应的图像帧，电子设备利用LCD驱动可接收合成的图像帧，由LCD显示合成的图像帧，以实现显示应用窗口动效。
示例性的，如图7中(c)所示界面703，电子设备在获取窗口信息后，能够显示应用窗口动效。并且，如图7中(d)所示界面704，显示图库应用主界面，结束应用启动动效的显示，完成图库应用的启动。
如此，响应于用户启动应用的操作，电子设备能够通过WMS基于获得的应用图标对应的bitmap创建应用图标动效，并且通过WMS创建应用窗口动效，实现包含应用图标动效和应用窗口动效的应用启动动效的显示。进而由WMS创建应用启动动效，能够避免出现由于桌面创建应用图标动效以及WMS创建应用窗口动效导致的动效衔接异常，造成的闪现、错位等异常卡顿问题，提升用户使用体验。
此外，电子设备将应用图标动效和应用窗口动效全部配置为由WMS创建，则能够避免出现由于桌面绘制应用图标图层的延时异常导致的WMS绘制应用窗口图层异常。比如，WMS在绘制应用窗口图层过程中，由于用户界面(user interface，UI)线程没能及时得到调度导致出现丢帧异常。
在一些场景中，WMS在接收到应用图标对应的bitmap后，可以不创建图层，而是直接利用应用窗口对应的图层生成应用图标对应的图层数据，减少图层创建步骤，提升动效显示效率。
可选的，图8为本申请实施例提供的显示方法中，显示应用启动动效步骤的第二种实施方式的具体流程图，S502还可以具体实现为如图8所示的S801-S809中任意一 个或多个步骤的组合。
S801、响应于应用启动操作，桌面确定应用图标对应的位图(bitmap)。
S802、桌面向WMS发送应用图标对应的位图。
其中，S801-S802可以参考上述S601-S602的相关描述，在此不再赘述。
S803、WMS根据应用图标对应的位图和应用窗口对应的图层，确定应用图标对应的图层数据。
在一些实施例中，WMS在接收到应用图标对应的位图后，获取应用窗口对应的图层，将应用图标对应的位图填入应用窗口对应的图层，获得应用图标对应的图层数据。
需要说明的是，虽然在S803中，WMS没有为应用图标建立对应的图层，但是WMS能够获取到应用图标对应的位图，将该位图填入应用窗口对应的图层，此时WMS还未获取到应用窗口内容数据(即还未开始显示应用窗口动效)，因此，在应用窗口图层内仅包含填入的应用图标对应的位图，实现由WMS控制应用图标动效。相比于现有技术，桌面控制应用图标动效，WMS创建的应用窗口图层内不会包含应用图标数据。基于此，若对应用图标动效显示过程中的应用窗口图层内的数据进行获取，则可以获取到应用图标数据。
S804、WMS向SurfaceFlinger发送应用图标对应的图层数据。
S805、SurfaceFlinger合成应用图标对应的图层数据，以显示应用图标动效。
其中，S804-S805可以参考上述S604-S605的相关描述，在此不再赘述。
S806、WMS获取应用窗口信息，删除应用图标对应的位图。
S807、WMS根据应用窗口信息，确定应用窗口对应的图层数据。
在一些实施例中，在S806和S807中，WMS获得的应用窗口信息例如包括接收到的应用程序发送的应用窗口内容数据，WMS在接收到应用窗口内容数据后，确定需要显示应用窗口动效，但当前应用窗口图层被应用图标对应的位图占用，因此需要删除应用图标对应的位图。之后，将应用窗口内容数据填入已删除应用图标对应的位图的应用窗口图层中，获得应用窗口对应的图层数据。
示例性的，如图7中(b)所示界面702，电子设备在显示应用图标动效后，会显示如图9所示界面901中所示的应用窗口动效。其中，如附图标记91指示的应用窗口为应用窗口动效过程中某一时刻的应用窗口显示效果。可以看出，由于WMS在删除应用图标对应的位图后，生成应用窗口对应的图层数据，因此在应用窗口动效显示过程中，不会覆盖显示应用图标动效。
S808、WMS向SurfaceFlinger发送应用窗口对应的图层数据。
S809、SurfaceFlinger合成应用窗口对应的图层数据，以显示应用窗口动效。
其中，S808-S809可以参考上述S607-S608的相关描述，在此不再赘述。
如此，响应于用户启动应用的操作，电子设备能够通过WMS基于获得的应用图标对应的bitmap创建应用图标动效，并且通过WMS创建应用窗口动效，实现包含应用图标动效和应用窗口动效的启动动效的显示。鸡儿，由WMS创建启动动效，能够避免出现由于桌面创建应用图标动效以及WMS创建应用窗口动效导致的动效衔接异常，导致的闪现、错位等异常卡顿问题，提升用户使用体验。
如上通过S502介绍了应用启动动效，如下通过S503介绍应用关闭动效。
S503、显示应用关闭动效。
在一些实施例中，电子设备检测到应用关闭操作后，则通过桌面关闭或暂停(如转为后台应用)该应用对应的活动(activity)，并调用WMS创建应用窗口动效以及应用图标动效，实现显示应用关闭动效。可以理解的是，应用关闭动效应与应用启动动效相对应且相反。比如，应用关闭动效例如包括应用窗口的缩小淡出动效以及应用图标的缩小淡入动效。
在一些实施例中，部分应用程序图标在电子设备桌面文件夹内显示，那么对于这部分应用的应用关闭动效中的应用图标动效还应包括应用图标对应的文件夹的文件夹动效。
示例性的，如图10中(a)所示界面1001，控件101为实用工具文件夹对应的打开控件，电子设备检测到用户点击控件101的操作后，打开实用工具文件夹，显示如图10中(b)所示界面1002。在界面1002上显示有实用工具卡片102，并在实用工具卡片102上显示有分类为实用工具应用的应用的图标，如计算器应用图标103。电子设备检测到用户点击计算器应用图标103的操作后，打开计算器应用并显示如图10中(c)所示的计算器主界面1003。基于此，如需关闭计算器应用，在显示应用关闭动效的过程中，还应显示实用工具卡片(即应用对应的文件夹)动效。
可选的，图11为本申请实施例提供的显示方法中，显示应用关闭动效步骤的第一种实施方式的具体流程图，S503可以具体实现为如图11所示的S1101-S1110中任意一个或多个步骤的组合。
S1101、响应于应用关闭操作，桌面确定应用图标对应的位图(bitmap)。
在一些实施例中，如上述S501所述，桌面检测到应用关闭操作，如检测到用户在应用显示界面上的上滑返回桌面的操作，获取应用图标对应的信息，例如包括应用图标的位置、大小、形状、图标中包含的透明区域尺寸等信息，确定应用图标对应的bitmap。可选的，应用图标对应的信息还可以包括应用图标对应的文件夹信息(如文件夹位置、大小、形状等信息)，那么WMS确定的bitmap包括文件夹对应的bitmap。应用图标可以为单层图标，也可以为双层图标或多层图标。
S1102、桌面向WMS发送应用图标对应的位图。
在一些实施例中，桌面在确定应用图标对应的bitmap后，将该应用图标对应的bitmap发送至WMS，用于指示WMS生成bitmap对应的图层数据。可选的，桌面通过调用桌面进程通过binder IPC方式向WMS调用的系统服务进程发送应用图标对应的bitmap。相应的，WMS接收桌面发送的应用图标对应的bitmap。
S1103、WMS获取应用窗口信息，根据应用窗口信息和应用图标对应的位图，确定应用窗口对应的图层数据。
在一些实施例中，应用窗口信息例如包括应用窗口对应的图层以及接收到的应用程序发送的应用窗口内容数据。WMS根据应用图标对应的bitmap确定应用图标对应的图标信息，利用图标信息对应用窗口内容数据进行裁剪，比如裁剪应用图标透明区域，确定应用窗口对应的图层数据。从而使得在显示应用图标动效和应用窗口动效衔接过程中，实现应用图标的淡入显示效果。
其中，S1103的其他内容可以参考上述S606的相关描述，在此不再赘述。
S1104、WMS向SurfaceFlinger发送应用窗口对应的图层数据。
在一些实施例中，WMS在确定应用窗口对应的图层数据后，向SurfaceFlinger发送应用窗口对应的图层数据。相应的，SurfaceFlinger接收应用窗口对应的图层数据。
S1105、SurfaceFlinger合成应用窗口对应的图层数据，以显示应用窗口动效。
在一些实施例中，SurfaceFlinger接收到应用窗口对应的图层数据后，调用合成线程对接收的应用窗口对应的图层数据进行图层合成得到对应的图像帧，电子设备利用LCD驱动可接收合成的图像帧，由LCD显示合成的图像帧，以实现显示应用窗口动效。
S1106、WMS确定存在应用图标对应的图层。若否，则执行S1107；若是，则执行S1108。
在一些实施例中，如上述S603所述，在应用启动过程中，WMS会建立应用图标对应的图层，并且在电子设备未满足预设条件的情况下，不会删除该图层。因此，WMS在接收到应用图标对应的bitmap后，需要确定是否存在应用图标对应的图层。若存在，则直接利用该图层生成应用图标对应的图层数据；若不存在，则需要先创建应用图标对应的图层，再生成应用图标对应的图层数据。
S1107、WMS创建应用图标对应的图层。
在一些实施例中，WMS确定电子设备中未存储应用图标对应的图层，则创建图层，并将该图层挂载于当前绘制的用于动效显示的多个图层中的最底层。可选的，WMS存储该创建的应用图标对应的图层，用于后续应用启动动效显示过程或应用关闭动效显示过程。
S1108、WMS根据应用图标对应的位图和应用图标对应的图层，确定应用图标对应的图层数据。
在一些实施例中，WMS确定存在应用图标对应的图层，或者创建应用图标对应的图层后，将在上述S1102中接收到的应用图标对应的bitmap填入应用图标对应的图层中，生成应用图标对应的图层数据，用于显示应用图标动效。
S1109、WMS向SurfaceFlinger发送应用图标对应的图层数据。
在一些实施例中，WMS在确定应用图标对应的图层数据后，将确定的图层数据发送至SurfaceFlinger进行合成，以获得用户可见的图像帧。相应的，SurfaceFlinger接收应用图标对应的图层数据。
S1110、SurfaceFlinger合成应用图标对应的图层数据，以显示应用图标对应的动效。
在一些实施例中，SurfaceFlinger接收到应用图标对应的图层数据后，调用合成线程对接收的应用图标对应的图层数据进行图层合成得到对应的图像帧，电子设备利用LCD驱动可接收合成的图像帧，由LCD显示合成的图像帧，以实现显示应用图标动效。
示例性的，如图12所示，以关闭图库应用为例，对上述图11所示的方法的实现方式进行说明。如图12中(a)所示界面1201，电子设备显示图库应用界面。电子设备检测到用户在界面1201上沿箭头121所示方向的上滑操作，确定关闭图库应用，获取应用窗口内容信息创建对应的图层数据，合成图层数据后，则显示图库应用窗口对 应的动效。如图12中(b)所示界面1202中附图标记122指示的缩小后的应用窗口为应用窗口动效中某一时刻的应用窗口的显示效果，此时应用图标对应的图层数据还未创建，用户不可见应用图标。之后，WMS根据获取到的图库应用图标对应的bitmap，创建对应的图层数据，合成图层数据后显示图库图标对应的动效。如图12中(c)所示界面1203中附图标记123指示的缩小后的应用窗口为应用窗口动效中某一时刻的应用窗口的显示效果，用户可见如附图标记124指示的缩小过程中的应用图标，实现应用窗口的缩小淡出动效以及应用图标的缩小淡入动效。之后，如图12中(d)所示界面1204，此时用户可见附图标记125指示的应用图标动效，直至应用图标缩小至预设大小，显示如图12中(e)所示界面1205，完成图库应用关闭动效的显示，关闭图库应用。
可以看出，在上述图库应用关闭过程中，均由WMS创建应用关闭动效，因此在如图12中(b)至如图12中(d)所示应用关闭动效显示过程中，不会出现卡顿异常，提升用户使用体验。
在一些场景中，如上述S1101所述，应用图标对应的信息可能包括文件夹信息，那么在显示应用关闭动效的过程中，应显示文件夹动效。
示例性的，对应于图10所示的计算器应用启动场景，如图13所示为计算器应用关闭场景。电子设备显示如图13中(a)所示计算器界面1301，检测到关闭计算器应用的操作后，确定关闭计算器应用。获取窗口内容信息创建对应的图层数据，合成图层数据后，则显示计算器应用窗口对应的动效。如图13中(b)所示界面1302中附图标记131指示的缩小后的应用窗口为应用窗口动效中某一时刻的应用窗口的显示效果。之后，WMS根据获取到的计算器应用图标对应的bitmap(如实用工具文件夹对应的bitmap)，创建对应的图层数据，合成图层数据后显示实用工具文件夹对应的动效。如图13中(c)所示界面1303中附图标记132指示的缩小后的实用工具文件夹卡片为实用工具文件夹动效中某一时刻的实用工具文件夹卡片的显示效果。之后，如图13中(d)所示界面1304，直至实用工具文件夹卡片缩小至预设大小，显示如图13中(d)所示界面1304，完成计算器应用关闭动效的显示，关闭计算器应用。可选的，在界面1303和界面1304之间还可以显示包含计计算器图标动效的界面。
可以看出，在上述计算器应用关闭过程中，均由WMS创建应用关闭动效，因此在如图13中(b)至如图13中(d)所示应用关闭动效显示过程中，不会出现卡顿异常，提升用户使用体验。
在一些场景中，上述S1106-S1110还可以在S1103之前执行，也就是说WMS在接收到应用图标对应的位图后，先确认是否存在应用图标对应的图层，创建应用图标动效，但此时显示的应用图标对应的图像帧用户不可见(例如为淡入显示效果)。在创建应用窗口动效后，应用窗口图层在应用图标图层之上覆盖显示。比如，如12中(b)所示界面1202，在附图标记122指示的应用窗口动效之下可以显示有用户不可见的应用图标动效。
在另一些场景中，上述S1106和S1107还可以在S1103之前执行，也就是说WMS在接收到应用图标对应的位图后，先确认是否存在应用图标对应的图层，确认是否需要创建应用图标对应的图层。之后，WMS再创建应用窗口动效。在当前场景中，WMS 在执行S1107后执行S1103。
如此，响应于用户关闭应用的操作，电子设备能够通过WMS创建应用窗口动效，并且通过WMS基于获得的应用图标对应的bitmap创建应用图标动效，实现包含应用窗口动效和应用图标动效的用于关闭动效的显示。进而由WMS创建应用关闭动效，能够避免出现由于WMS创建应用窗口动效以及桌面创建应用图标动效导致的动效衔接异常，造成的闪现、错位等异常卡顿问题，提升用户使用体验。
在一些场景中，对应于图8所示的应用启动动效显示方法，WMS不创建应用图标对应的图层，而是直接利用应用窗口对应的图层生成应用图标对应的图层数据，那么在WMS创建应用关闭动效过程中，也不必确认是否存在应用图标对应的图层，而是直接利用应用窗口图层创建应用图标动效。
可选的，图14为本申请实施例提供的显示方法中，显示应用关闭动效步骤的第二种实施方式的具体流程图，S502还可以具体实现为如图14所示的S1401-S1408中任意一个或多个步骤的组合。
S1401、WMS响应于活动关闭或暂停消息，获取应用窗口信息，根据应用窗口信息，确定应用窗口对应的图层数据。
在一些实施例中，如上述S501所述，电子设备在检测到应用关闭操作后，则通过桌面进程向系统服务进程发送活动关闭(StopActivity)消息或活动暂停(PauseActivity)消息。相应的，WMS在接收到StopActivity消息或PauseActivity消息后，确定需要开始创建应用关闭动效。在当前场景中，应用图标对应的bitmap与应用窗口内容数据均对应于同一个图层，基于此，WMS在确定需要显示应用窗口动效时，获取应用窗口信息，将应用窗口内容数据填入应用窗口对应的图层，生成应用窗口对应的图层数据。
S1402、WMS向SurfaceFlinger发送应用窗口对应的图层数据。
S1403、SurfaceFlinger合成应用窗口对应的图层数据，以显示应用窗口动效。
其中，S1402-S1403可以参考上述S1104-S1105的相关描述，在此不再赘述。
S1404、响应于应用关闭操作，桌面确定应用图标对应的位图(bitmap)。
S1405、桌面向WMS发送应用图标对应的位图。
其中，S1404-S1405可以参考上述S1101-S1102的相关描述，在此不再赘述。
S1406、WMS根据应用图标对应的位图和窗口对应的图层，确定应用图标对应的图层数据。
在一些实施例中，WMS将应用窗口对应的图层中在上述S1401中填入的应用窗口内容数据删除，将获取到的应用图标对应的bitmap填入应用窗口对应的图层，生成应用图标对应的图层数据。
示例性的，如图12中(a)所示界面1201，电子设备在检测到关闭图库应用的操作后，会显示如图15中(a)所示界面1501中所示的应用窗口动效，在该应用窗口动效之下未覆盖应用图标动效。其中，如附图标记151指示的应用窗口为应用窗口动效过程中某一时刻的应用窗口的显示效果。之后，在WMS创建应用图标动效后，结束显示应用窗口动效，直接显示如图15中(b)所示的界面1502中所示的应用图标动效。其中，如附图标记152指示的应用图标为应用图标动效过程中某一时刻的应用图标的显示效果。
S1407、WMS向SurfaceFlinger发送应用图标对应的图层数据。
S1408、SurfaceFlinger合成应用图标对应的图层数据，以显示应用图标对应的动效。
其中，S1407-S1408可以参考上述S1109-S1110的相关描述，在此不再赘述。
在一些场景中，上述S1404和S1405还可以在S1401之前执行，也就是说WMS可以在接收到应用图标对应的位图后，再创建应用窗口对应的图层数据。
如此，响应于用户关闭应用的操作，电子设备能够通过WMS创建应用窗口动效，并且通过WMS基于获得的应用图标对应的bitmap创建应用图标动效，实现包含应用窗口动效和应用图标动效的关闭动效的显示。进而由WMS创建应用关闭动效，能够避免出现由于WMS创建应用窗口动效以及桌面创建应用图标动效导致的动效衔接异常，造成的闪现、错位等异常卡顿问题，提升用户使用体验。
