Description

显示方法与装置、电子设备
本发明要求2022年11月30日递交的发明名称为“显示方法与装置、电子设备”的申请号202211521939.3的在先申请优先权，上述在先申请的内容以引入的方式并入本文本中。
技术领域
本申请涉及显示领域，具体涉及一种显示方法与装置、电子设备。
背景技术
目前，随着柔性屏技术的发展，各类折叠屏幕已应用于电子设备中，以便尽可能增大电子设备上用于显示的区域，而用户也可以对折叠屏幕做出展开或者各种折叠角度的操作，以便满足在各类场景下的屏幕显示需求，获得更好的视觉体验感。
通常，用户会根据自身的需求将折叠屏幕沿着可折叠的部位进行向内或向外折叠，使得折叠屏幕从未折叠状态进入悬停状态，并将折叠屏幕的整个显示区域分成两个显示区域。其中，非折叠状态，可以理解为，折叠屏幕未被折叠而呈现完全展开的状态；悬停状态，可以理解为，折叠屏幕未被完全折叠(如半折叠)而呈现一定折叠角度的状态。
然而，当具有折叠屏幕的电子设备从未折叠状态进入悬停状态时，如何在电子设备进入悬停状态下进行相关显示，还需要进一步研究。
发明内容
本申请实施例提供了一种显示方法与装置、电子设备，以期望解决如何在电子设备进入悬停状态下进行相关显示的问题。
第一方面，为本申请的一种显示方法，包括：
响应于电子设备进入悬停状态，将目标应用的第一界面内容显示在所述电子设备的第一显示区域上，以及将所述目标应用的第二界面内容显示在所述电子设备的第二显示区域上；
其中，所述第一界面内容具有不向用户提供操作所述目标应用的功能，所述第二界面内容具有向用户提供操作所述目标应用的功能；或者，
所述第一界面内容具有不响应于用户对所述第一显示区域的触控事件的功能，所述第二界面内容具有响应于用户对所述第二显示区域的触控事件以操作所述目标应用的功能。
可见，在电子设备进入悬停状态时，本申请实施例可以将目标应用的界面内容分成两类，即第一界面内容和第二界面内容，并将第一界面内容和第二界面内容分别显示在电子设备(折叠屏幕)的两个显示区域上，即第一显示区域显示第一界面内容，而第二显示区域显示第二界面内容，从而实现将目标应用的界面内容进行视觉上的UI分离。
这样，当用户想要去操作该目标应用时，通过将该目标应用的界面内容进行分类以分别显示在不同显示区域上，如此可以将用于操作该目标应用的界面内容显示在用户更容易操作的显示区域上，以便有利于避免因用户的触控而导致显示区域发生摆动以改变折叠角度等情况，提升用户的使用体验。
第二方面，为本申请的一种显示装置，包括：
显示单元，用于响应于电子设备进入悬停状态，将目标应用的第一界面内容显示在所述电子设备的第一显示区域上，以及将所述目标应用的第二界面内容显示在所述电子设备的第二显示区域上；
其中，所述第一界面内容具有不向用户提供操作所述目标应用的功能，所述第二界面内容具有向用户提供操作所述目标应用的功能；或者，
所述第一界面内容具有不响应于用户对所述第一显示区域的触控事件的功能，所述第二具有响应于用户对所述第二显示区域的触控事件以操作所述目标应用的功能。
第三方面，为本申请的一种电子设备，包括处理器、存储器及存储在所述存储器上的计算机程序或指令，所述处理器执行所述计算机程序或指令以实现上述第一方面中所述方法的步骤。
第四方面，为本申请的一种计算机可读存储介质，其中，所述计算机可读存储介质上存储有计算机程序或指令，所述计算机程序或指令被处理器执行时以实现上述第一方面中所述方法的步骤。
第五方面，为本申请的一种计算机程序产品，包括计算机程序或指令，其中，所述计算机程序或指令被处理器执行时实现上述第一方面中所述方法的步骤。
第二方面至第五方面的技术方案所带来的有益效果可以参见第一方面的技术方案所带来的技术效果，此处不再赘述。

3、电子设备的软件架构
本申请实施例中，电子设备的软件架构可以采用分层架构、事件驱动架构、微核架构、微服务架构或云架构。下面本申请实施例以分层架构的Android系统为例，示例性说明电子设备的软件架构。
在一些可能的实现中，电子设备可以包括内核层、系统运行库层、应用框架层和应用层等中的至少一项。
其中，层与层之间通过软件接口通信，并且内核层、系统运行库层和应用框架层属于操作系统空间。
1)应用层
在一些可能的实现中，应用层属于用户空间，应用层上运行有至少一个应用程序(或简称为“应用”)，这些应用程序可以是操作系统自带的原生应用程序，也可以是第三方开发者所开发的第三方应用程序。
例如，应用层可以包括相机、图库、日历、通话、地图、导航、WLAN、蓝牙、音乐、消息通知、视频和短信息等应用程序。
2)应用框架层
在一些可能的实现中，应用框架层可以提供构建应用层的应用程序可能用到的各种应用编程接口(application programming interface，API)和编程框架，从而开发者也可以通过使用这些API来构建自己的应用程序。
例如，窗口管理器(window manager)、内容提供器(content providers)、视图系统(view system)、电话管理器(telephony manager)、资源管理器、通知管理器(notification manager)、消息管理器、活动管理器(activity manager)、包管理器(package manager)、位置管理(location manager)和NFC服务等。
具体的，窗口管理器可以用于管理窗口程序。窗口管理器可以获取显示屏大小，判断是否有状态栏、锁定屏幕、截取屏幕等。
具体的，内容提供器可以用于存放和获取数据，并使该数据可以被应用程序访问。其中，该数据可以包括视频、图像、音频、拨打和接听的电话、浏览历史和书签、电话簿等。另外，内容提供器可以使得应用程序可以访问另一个应用程序的数据，如联系人数据库，或者共享它们自己的数据。
具体的，视图系统包括可视控件。例如，显示文字的控件和显示图片的控件等。视图系统可以用于构建应用程序。显示界面可以由一个或多个视图组成的。例如，包括短信通知图标的显示界面，可以包括显示文字的视图以及显示图片的视图。

具体的，消息管理器可以用于存储各个应用程序上报的消息的数据，并对各个应用程序上报的数据进行处理。
具体的，活动管理器可以用于管理应用程序生命周期并提供常用的导航回退功能。在一种可能的示例中，消息管理器可以是通知管理器的一部分。
3)系统运行库层
在一些可能的实现中，系统运行库层可以通过一些C/C++库来为Android系统提供了主要的特性支持。如SQLite库提供了数据库的支持，OpenGL/ES库提供了3D绘图的支持，Webkit库提供了浏览器内核的支持等。在系统运行库层340中还提供有安卓运行时库(Android Runtime)，其主要提供了一些核心库，能够允许开发者使用Java语言来编写Android应用。
4)内核层
在一些可能的实现中，内核层可以为电子设备的各种硬件提供了底层的驱动，如显示驱动、音频驱动、摄像头驱动、蓝牙驱动、Wi-Fi驱动、电源管理、NFC驱动、UWB驱动等。
二、一种显示方法
1、描述
目前，当具体折叠屏幕的电子设备从未折叠状态进入悬停状态时，通常是将折叠屏幕的整个显示区域上的应用窗口中所显示的界面内容，通过调整该应用窗口的大小以置于上部分显示区域，且该应用的 界面内容会整个显示在上部分显示区域，而下部分显示区域上只显示一个触控面板(Touch Panel)窗口，该触控面板窗口可以是设备厂商自定义的窗口，用于映射用户的应用触控事件以操作该应用，如映射左/右滑动快进、上下滑调节亮度/音量等应用触控事件。
然而，由于该应用的界面内容整个显示在上部分显示区域上，因此上部分显示区域上会向用户提供整个操作应用的功能，而下部分显示区域上只会向用户提供部分操作应用的功能，且功能相对单一，但是用户想要完整操作该应用，只能去触控上部分显示区域。此时，由于折叠屏处于半合状态，因此用户去触控上部分显示区域时会存在操作困难，容易因用户操作而退出悬停模式，导致用户体验不佳等。
例如，在图3的(a)中，折叠屏幕310处于未折叠状态，且折叠屏幕310的整个显示区域上的应用窗口320中显示有音乐播放应用的界面内容。其中，该界面内容可以包括，评论图标3301、分享图标3302、暂停/播放图标3303、上一曲图标3304、进度条3305等视图内容，以及文字3306、动态图像3307等视图内容，而用户可以操作/触控评论图标3301等视图内容来操作该音乐播放应用，但用户无法操作/触控文字3306等视图内容来操作该音乐播放应用。比如，用户可以点击评论图标3301来对该音乐播放应用所播放的音乐进行评论等。
在图3的(b)中，折叠屏幕310从未折叠状态进入悬停状态以使得折叠屏幕310的整个显示区域沿着折叠部位340分成显示区域3501和显示区域3502。其中，该音乐播放应用的界面内容整个显示在显示区域3501上的应用窗口3601中，而显示区域3502上的应用窗口3602中只显示一个触控面板窗口，而用户可以在该触控面板窗口上进行左/右滑动以对该音乐播放应用所播放的音乐进行快进，可以在该触控面板窗口上进行上下滑动来调节该音乐播放应用所播放的音乐的音量等，但该触控面板窗口所能提供的功能还是相对简单且少量，如该触控面板窗口无法提供评论、分享等功能。
此时，当用户需要对该音乐播放应用所播放的音乐进行评论、分享时，用户仍然需要去触控显示区域3501。由于折叠屏幕310处于半合状态，使得显示区域3501处于倾斜状态，因此用户去触控显示区域3501时可能存在操作不便，容易因用户的触控而导致显示区域3501和显示区域3502发生摆动以改变折叠角度等情况，从而影响用户使用折叠屏幕310的体验感。
基于此，本申请实施例提出了一种显示方法，以便解决用户操作不便，避免因用户的触控而导致显示区域发生摆动以改变折叠角度等情况，提升用户的该折叠屏幕的体验感。
下面对本申请实施例的一种显示方法进行说明。
如图4所示，图4是本申请实施例的一种显示方法的流程示意图，该方法可以应用于电子设备，可以包括如下步骤：
S410、响应于电子设备进入悬停状态，将目标应用的第一界面内容显示在第一显示区域上，以及将目标应用的第二界面内容显示在第二显示区域上，其中，第一界面内容具有不向用户提供操作目标应用的功能，第二界面内容具有向用户提供操作所述目标应用的功能；或者，第一界面内容具有不响应于用户对第一显示区域的触控事件的功能，第二界面内容具有响应于用户对第二显示区域的触控事件以操作目标应用的功能。
可见，在电子设备进入悬停状态时，本申请实施例可以将目标应用的界面内容分成两类，即第一界面内容和第二界面内容，并将第一界面内容和第二界面内容分别显示在两个显示区域上，即第一显示区域显示第一界面内容，而第二显示区域显示第二界面内容，从而实现将目标应用的界面内容进行视觉上的用户界面(user interface，UI)分离。
这样，当用户想要去操作该目标应用时，通过将该目标应用的界面内容进行分类以分别显示在不同显示区域上，如此可以将用于操作该目标应用的界面内容显示在用户更容易操作的显示区域上，以便有利于避免因用户的触控而导致显示区域发生摆动以改变折叠角度等情况，提升用户的使用体验。
例如，在图3的(c)中，折叠屏幕310从未折叠状态进入悬停状态以使得折叠屏幕310的整个显示区域沿着折叠部位340分成显示区域3501和显示区域3502。
然后，将该音乐播放应用的界面内容进行分类，如评论图标3301、分享图标3302、暂停/播放图标3303、上一曲图标3304等视图内容为一类视图内容，而文字3306、动态图像3307等视图内容为另一类视图内容。其中，用户可以操作/触控评论图标3301、分享图标3302等这类视图内容来操作该音乐播放应用，但用户无法操作/触控文字3306等这类视图内容来操作该音乐播放应用。
最后，将评论图标3301、分享图标3302等这类视图内容显示在显示区域3502上的应用窗口3602中，而将文字3306、动态图像3307等这类视图内容显示在显示区域3501上的应用窗口3601中。
这样，当用户需要对该音乐播放应用所播放的音乐进行评论、分享时，用户只需去触控显示区域3502。相对于图3的(b)中需要去触控显示区域3501，用户触控显示区域3502会更加便捷和容易，能够避免折叠屏幕310发生折叠角度改变等情况，提升用户的使用体验。
2、具体实现说明
下面对上述图4所涉及的一些实现方式进行具体说明。
(1)电子设备处于非折叠状态的整个显示区域、第一显示区域和第二显示区域
1)描述
需要说明的是，在电子设备的折叠屏幕未被折叠时，折叠屏幕处于完全平铺的非折叠状态。此时，电子设备处于非折叠状态，并且折叠屏幕可以在整个显示区域上进行显示，如图1所示。
当用户根据自身的需求将折叠屏幕沿着可折叠的部位进行向内或向外折叠时，折叠屏幕的整个显示区域分成两个显示区域。为了便于区分，该两个显示区域分别称为“第一显示区域”和“第二显示区域”。
在一些可能的实现中，电子设备(折叠屏幕)从未折叠状态进入悬停状态以使得折叠屏幕的整个显示区域分成第一显示区域和第二显示区域。
在一些可能的实现中，电子设备(折叠屏幕)从未折叠状态进入悬停状态以使得折叠屏幕的整个显示区域沿着折叠部位分成第一显示区域和第二显示区域。
具体的，当第一显示区域为折叠屏幕的左边显示区域(上边显示区域)时，第二显示区域为折叠屏幕的右边显示区域(下边显示区域)，对此不作具体限制。
具体的，当第一显示区域为折叠屏幕的右边显示区域(下边显示区域)时，第二显示区域为折叠屏幕的左边显示区域(上边显示区域)，对此不作具体限制。
具体的，第一显示区域与第二显示区域可以具有相同的面积。也就是说，折叠屏幕的整个显示区域被分成相同面积的两半。这样，第一显示区域与第二显示区域可以完全重叠。
具体的，第一显示区域与第二显示区域也可以不具有相同的面积。也就是说，折叠屏幕的整个显示区域被分成不相同面积的两个显示区域，对此不作具体限制。
(2)目标应用的界面内容
需要说明的是，具有折叠屏幕的电子设备可以运行应用，使得折叠屏幕可以对该应用的界面内容进行显示。下面进行具体说明。
1)目标应用
应用，可以称为应用程序(application)。其中，应用程序，可以是指为完成某项/多项特定工作或具有某种功能的程序，而程序是运行于操作系统上的，可以运行在应用层上与用户进行交互，具有可视的用户界面或应用窗口。
例如，应用可以运行在上述“3、电子设备的软件架构”中的应用层上。
需要说明的是，本申请实施例的目标应用只是特指电子设备(折叠屏幕)进入悬停状态所运行的应用，主要是用于区分，本质上就是应用。
在一些可能的实现中，目标应用可以具有不同的类型，如视频类应用、音乐类应用、直播类应用等。
在一些可能的实现中，折叠屏幕处于非折叠状态下所显示的应用的类型，可能与折叠屏幕处于悬停状态下所显示的目标应用的类型不同。
例如，折叠屏幕处于非折叠状态下所显示的应用为视频类应用，而折叠屏幕从非折叠状态进入悬停状态下所显示的应用为音乐类应用。
在一些可能的实现中，折叠屏幕处于非折叠状态下所显示的应用的类型，可能与折叠屏幕处于悬停状态下所显示的目标应用的类型相同。也就是说，折叠屏幕处于非折叠状态下所显示的应用与折叠屏幕处于悬停状态下所显示的目标应用为同一个应用。
2)应用窗口
需要说明的是，当具有折叠屏幕的电子设备运行应用时，通常会在显示区域上显示该应用对应的应用窗口，而该应用的界面内容可以在该应用窗口中显示。
具体的，该应用窗口的大小可以占用折叠屏幕的整个显示区域。
例如，应用窗口的大小可以占用图1所示的折叠屏幕110的整个显示区域。
又例如，在图2中，应用窗口2401的大小可以占用整个显示区域2201；应用窗口2402的大小可以占用整个显示区域2202，对此不作具体限制。
具体的，该应用窗口以悬浮的方式显示在折叠屏幕的显示区域上。
3)界面内容
需要说明的是，目标应用的界面内容，可以理解为，在运行该目标应用之后，用于组成该目标应用的视图/界面的所有元素或内容，用户可以直观进行查看，也可以对相应界面内容进行触控以操作该应用。
具体的，界面内容，可以由多种视图内容组成，且不同的视图内容可以提供不同的功能，或者不同 的视图内容可以呈现出不同的视觉效果。
4)界面内容的分类
①按照是否能操作目标应用来分类
需要说明的是，本申请实施例可以按照是否能操作目标应用来将该目标应用的界面内容进行分类。对此，界面内容的类型可以包括非操作类界面内容(或者称为“不可操作类界面内容”)和操作类界面内容(或者称为“可操作类界面内容”)。
具体的，非操作类界面内容，可以具有不向用户提供操作该目标应用的功能，或者不具有操作该目标应用的功能。因此，用户不能操作/触控这类视图内容来操作该目标应用。
例如，在图3中，该非操作类界面内容可以包括文字3306、动态图像3307等，而用户无法操作/触控这类视图内容来操作音乐播放应用。
具体的，操作类界面内容，可以具有向用户提供操作该目标应用的功能，或者具有操作该目标应用的功能。因此，用户可以操作/触控这类视图内容来操作该目标应用。
例如，在图3中，该操作类界面内容可以包括评论图标3301、分享图标3302、暂停/播放图标3303、上一曲图标3304、进度条3305等，而用户可以操作/触控这类界面内容来对该音乐播放应用所播放的音乐进行评论、分享、暂停/播放、切换、快进等操作。
②按照是否能响应对折叠屏幕的触控事件来分类
需要说明的是，本申请实施例的折叠屏幕可以是被触控(点击/触摸等)的。因此，用户可以触控(点击/触摸等)该折叠屏幕来执行相应的事件。比如，用户可以在该折叠屏幕的显示区域中的特定位置进行滑动来调节该折叠屏幕的显示亮度。
基于此，本申请实施例可以按照是否能响应对折叠屏幕的触控事件来将目标应用的界面内容进行分类。对此，界面内容的类型可以包括非响应类界面内容(或者称为“不可响应类界面内容”)和响应类界面内容(或者称为“可响应类界面内容”)。
具体的，非响应类界面内容，可以具有不响应于用户对的触控事件的功能。因此，当用户触控折叠屏幕以生成相应的触控事件时，这类界面内容不会响应于该触控事件，从而无法对目标应用进行相应的操作。
例如，在图3中，该非响应类界面内容可以包括文字3306、动态图像3307等，而这类界面内容无法响应于用户对折叠屏幕310的触控。
具体的，响应类界面内容，可以具有响应于用户对的触控事件的功能。因此，当用户触控折叠屏幕以生成相应的触控事件时，这类界面内容会响应于该触控事件，从而对应用进行相应的操作。
例如，在图3中，该响应类界面内容可以包括评论图标3301、分享图标3302、暂停/播放图标3303、上一曲图标3304、进度条3305等，而这类界面内容会响应于用户对折叠屏幕310的触控，以便对该音乐播放应用所播放的音乐进行评论、分享、暂停/播放、切换、快进等操作。
5)第一界面内容、第二界面内容
①描述
结合上述“4)界面内容的分类”中的内容，为了便于区分和描述，本申请实施例引入第一界面内容和第二界面内容。
具体的，第一界面内容可以为非操作类界面内容，第二界面内容可以为操作类界面内容。对此，第一界面内容可以具有不向用户提供操作目标应用的功能；第二界面内容可以具有向用户提供操作目标应用的功能。
具体的，第一界面内容可以为非响应类界面内容，第二界面内容可以为响应类界面内容。对此，第一界面内容可以具有不响应于用户对折叠屏幕的触控事件的功能；第二界面内容可以具有响应于用户对折叠屏幕的触控事件以操作应用的功能。
在一些可能的实现中，第一界面内容不包含可触摸控件，第二界面内容包含可触摸控件。其中，该可触摸控件可以具有向用户提供操作目标应用的功能。
②组成
需要说明的是，无论是第一界面内容，还是第二界面内容，都有可能是由一个或多个类型的视图内容组成的。
下面以Android系统为例，对第一界面内容和第二界面内容的组成进行具体说明。
◆活动(Activity)、画布(Surface)、画布视图(SurfaceView)、纹理视图(TextureView)
在Android系统中，Activity可以是Android定义的应用组件，可以用于显示用户界面的组件，可以用于提供一个能让用户操作并与只交互的应用界面，该应用界面可以包含多个Activity。
具体的，Activity中的视图可以包括TextureView、按钮(Button)、图像视图(ImageView)、视图(View)等。其中，TextureView可以是把内容流作为外部纹理输出在上面的图层，其自身需要一个硬件加速层。
具体的，Surface，可以是“表面”/“画布”的意思，可以是将图形缓冲区(graphic buffer)绘制到其中的对象，可以为内存中的图形缓冲区，可以由屏幕显示内容合成器(screen compositor)所管理的原生缓冲器的句柄。因此，通过Surface(因为Surface是句柄)就可以获得原生缓冲器(rawbuffer)中的内容，而原生缓冲器可以用于保存绘制应用窗口所显示的界面内容的相关数据等。
由于目标应用的界面内容都是通过Surface呈现出来的，而目标应用的界面内容可以是由各类的视图内容组成的，因此该界面内容中的各类视图均需要通过Surface呈现。
具体的，目标应用的界面内容的类型可以包括SurfaceView的视图内容、Activity中的各类视图的视图内容等，如TextureView的视图内容、Button的视图内容、ImageView的视图内容、View的视图内容。
其中，SurfaceView自带有独立的Surface和图层(Layer)，而SurfaceView可以控制该Surface的格式、尺寸以及绘制位置等。对此，SurfaceView的视图内容可以由其自带的Surface呈现。另外，SurfaceView的视图内容的渲染可以放在单独的线程而不是应用的主线程中。
其中，Activity中的各类视图共享同一个Surface。对此，Activity中的各类视图的视图内容可以由同一个Surface呈现。另外，Activity中的各类视图的视图内容的渲染可以放在应用的主线程中。
例如，如图5所示，应用可以包含多个Activity，如Activity 5101、Activity 5102和Activity 5103，而每个Activity中的各类视图共享同一个Surface，SurfaceView自带一个Surface。
◆第一界面内容的组成、第二界面内容的组成
需要说明的是，第一界面内容与第二界面内容可以由互不相同的一个或多个视图内容组成。
例如，结合上述内容，第一界面内容可以包括以下至少一项：SurfaceView的视图内容、Activity中的TextureView的视图内容等；而第二界面内容可以包括以下至少一项：Activity中的Button的视图内容、Activity中的ImageView的视图内容、Activity中的View的视图内容等。
当然，第一界面内容和第二界面内容还可以包括其他视图内容，主要还是按照是否能操作应用，或者是否能响应对折叠屏幕的触控事件来进行划分，对此不作具体限制。
(3)如何将第一界面内容和第二界面内容进行分屏显示
需要说明的是，当用户根据自身的需求将折叠屏幕沿着可折叠的部位进行向内或向外折叠时，折叠屏幕从未折叠状态进入悬停状态以使得折叠屏幕分成第一显示区域和第二显示区域，而如何将第一界面内容显示在第一显示区域，以及将第二界面内容显示在第二显示区域上，如图6所示，可以采用如下步骤：
步骤1：判断是否向第一界面内容创建新的Surface
需要说明的是，当需要将第一界面内容显示在第一显示区域时，通常需要保证第一界面内容具有Surface，再通过该Surface来实现在该在第一显示区域上呈现第一界面内容。
然而，结合上述“5)第一界面内容、第二界面内容”中的内容，由于第一界面内容可以由各类视图内容组成，而第一界面内容中可能存在自带独立的Surface的视图内容(如SurfaceView的视图内容)，也可能不存在自带独立的Surface的视图内容，因此，本申请实施例需要先判断是否向第一界面内容创建新的Surface。
若第一界面内容仅不具有自带的Surface，则说明需要向第一界面内容创建新的Surface，并执行步骤2。
若第一界面内容具有自带的Surface以及不具有自带的Surface，则说明需要向第一界面内容创建新的Surface，并执行步骤3。
若第一界面内容仅具有自带的Surface，则说明不需要向第一界面内容创建新的Surface。
步骤2：向第一界面内容创建新的Surface
需要说明的是，若第一界面内容仅不具有自带的Surface，则本申请实施例可以向第一界面内容创建新的Surface。这样，本申请实施例可以得到第一显示区域上用于呈现第一界面内容的Surface，以便第一界面内容可以呈现在新创建的Surface上。
例如，以目标应用的界面内容包括Activity中的各类视图的视图内容，且第一界面内容包括Activity中的TextureView的视图内容为例，如图7所示，由于Activity中的各类视图的视图内容共享同一个Surface，使得TextureView的视图内容不具有自带的Surface，因此需要先创建新的Surface，再将TextureView的视图内容呈现在新的Surface上。
另外，在创建新的Surface的过程中，本申请实施例需要先创建一个新的画布控制视图持有 (SurfaceControlViewHost)，该SurfaceControlViewHost会持有独立的图层，并且会有一个子节点，该子节点可以命名为容器视图(ContainerView)，然后将TextureView的视图内容绘制到ContainerView上，从而实现将TextureView的视图内容呈现在新的Surface上。
例如，如图8所示，先向Activity SurfaceControl下的TextureView创建一个新的SurfaceControlViewHost。其中，该SurfaceControlViewHost分别具有根画布控制(RootSurfaceControl)和ContainerView两个子(son)节点，即该ContainerView的父级(parent)为该RootSurfaceControl，该RootSurfaceControl的父级为该SurfaceControlViewHos。然后，将TextureView的视图内容绘制到ContainerView上，使得TextureView的SurfaceControl称为该RootSurfaceControl，从而实现将TextureView的视图内容呈现在新的Surface上。
步骤3：将第一界面内容自带的Surface与向第一界面内容不具有自带的Surface的视图内容所新创建的Surface进行链接
需要说明的是，若第一界面内容中既存在不具有自带的Surface的视图内容，也存在具有自带的Surface的视图内容，则本申请实施例需要先向第一界面内容中不具有自带的Surface的视图内容创建新的Surface，再将不具有自带的Surface的视图内容呈现在新创建的Surface上，最后将第一界面内容自带的Surface与向第一界面内容不具有自带的Surface的视图内容所新创建的Surface进行链接。这样，本申请实施例可以得到第一显示区域上用于呈现第一界面内容的Surface。
例如，以应用的界面内容包括Activity中的各类视图的视图内容和SurfaceView的视图内容，且第一界面内容包括Activity中的TextureView的视图内容和SurfaceView的视图内容为例，如图9所示，由于Activity中的各类视图的视图内容共享同一个Surface，使得TextureView的视图内容不具有自带的Surface，因此需要先创建新的Surface，再将TextureView的视图内容呈现在新的Surface上，最后将SurfaceView自带的Surface与新的Surface进行链接。
另外，在创建新的Surface的过程中，本申请实施例需要先创建一个新的SurfaceControlViewHost，该SurfaceControlViewHost会持有独立的图层，并且会有一个子节点，即ContainerView，然后将TextureView的视图内容绘制到ContainerView上，从而实现将TextureView的视图内容呈现在新的Surface上。
在一些可能的实现中，将SurfaceView自带的Surface与新的Surface进行链接，可以包括将SurfaceView自带的Surface的SurfaceControl重定父级(reparent)到新的Surface的SurfaceControl。
例如，如图10所示，SurfaceView的自带的Surface的SurfaceControl的父级为Activity SurfaceControl。其中，Activity SurfaceControl为界面内容的SurfaceControl。因此，将SurfaceView自带的Surface的SurfaceControl重定父级到新的Surface的SurfaceControl，从而实现将SurfaceView自带的Surface与新的Surface进行链接。
综合上述步骤1至3可知，第一显示区域上用于呈现第一界面内容的Surface，可以为如下之一项：
第一界面内容自带的Surface、向第一界面内容新创建的Surface、第一界面内容自带的Surface与向第一界面内容中不具有自带的Surface的视图内容所新创建的Surface进行链接所得到的。
例如，若第一界面内容包括SurfaceView的视图内容，则第一显示区域上用于呈现SurfaceView的视图内容的Surface，可以为SurfaceView自带的Surface。
又例如，若第一界面内容包括Activity中的TextureView的视图内容，则第一显示区域上用于呈现TextureView的视图内容的Surface，可以为向SurfaceView新创建的Surface。
又例如，若第一界面内容包括SurfaceView的视图内容、Activity中的TextureView的视图内容，则第一显示区域上用于呈现第一界面内容的Surface，可以是SurfaceView的Surface与TextureView的Surface进行链接所得到的。
另外，综合上述步骤1-3可知，第一显示区域上用于呈现第一界面内容的Surface的SurfaceControl，可以是电子设备(折叠屏幕)处于非折叠状态下的整个显示区域上用于呈现界面内容的SurfaceControl下的子节点，也可以是新创建的。
例如，若第一界面内容包括SurfaceView的视图内容，则第一显示区域上用于呈现SurfaceView的视图内容的Surface的SurfaceControl，可以是界面内容的SurfaceControl下的子节点，如图10所示。
又例如，若第一界面内容包括Activity中的TextureView的视图内容，则第一显示区域上用于呈现SurfaceView的视图内容的Surface的SurfaceControl，可以是新创建的，如图8所示。
步骤4：创建新的第一显示区域上用于显示第一界面内容的应用窗口
需要说明的是，结合上述“2)应用窗口”中的内容，本申请实施例需要在第一显示区域上创建新的应用对应的应用窗口，再在该新创建的应用窗口中显示第一界面内容。此时，该新创建的应用窗口，可以称为第一显示区域上用于显示第一界面内容的应用窗口。
也就是说，第一显示区域上用于显示第一界面内容的应用窗口可以是新创建的。
另外，在新创建完成该应用窗口时，本申请实施例需要创建了该新创建的应用窗口的SurfaceControl。
步骤5：将第一显示区域上用于呈现第一界面内容的Surface，链接于该新创建的应用窗口
需要说明的是，为了保证在该新创建的应用窗口中显示第一界面内容，本申请实施例需要将上述所得到的第一显示区域上用于呈现第一界面内容的Surface，链接于该新创建的应用窗口。
具体的，该链接可以是采用如下步骤实现的：
将第一显示区域上用于呈现第一界面内容的Surface的SurfaceControl，重定父级到该创建的应用窗口的SurfaceControl，即第一显示区域上用于显示第一界面内容的应用窗口的SurfaceControl。
此时，第一显示区域上用于呈现第一界面内容的Surface的SurfaceControl的父级为该创建的应用窗口的SurfaceControl。
这样，本申请实施例可以通过重定父级来实现将第一显示区域上用于呈现第一界面内容的Surface链接于该新创建的应用窗口。
步骤6：对折叠屏幕的整个显示区域上用于显示界面内容的应用窗口进行窗口大小调整，得到第二显示区域上用于显示第二界面内容的应用窗口
需要说明的是，结合上述“2)应用窗口”中的内容，在第二显示区域上需要有应用窗口，以便在该应用窗口中显示第二界面内容，而本申请实施例可以对折叠屏幕的整个显示区域上用于显示界面内容的应用窗口进行窗口大小调整，以便得到第二显示区域上用于显示第二界面内容的应用窗口。
也就是说，第二显示区域上用于显示第二界面内容的应用窗口，可以是对电子设备(折叠屏幕)处于非折叠状态下的整个显示区域上用于显示界面内容的应用窗口进行窗口大小调整所得到的。
这样，只需通过应用窗口进行窗口大小调整，便能快速得到第二显示区域上用于显示第二界面内容的应用窗口，提高显示效率。
例如，在上述图9的基础上，如图11所示。其中，在折叠屏幕1110处于未折叠状态时，折叠屏幕1110的整个显示区域上的应用窗口1120显示应用的界面内容。其中，该界面内容包括Activity中的各类视图的视图内容和SurfaceView的视图内容，且第一界面内容包括Activity中的TextureView的视图内容和SurfaceView的视图内容。
在折叠屏幕1110从未折叠状态进入悬停状态以使得折叠屏幕1110的整个显示区域沿着折叠部位分成第一显示区域1130和第二显示区域1140时，第一显示区域1130上显示新创建的应用窗口1150，而第二显示区域1140上显示经过应用窗口1120的窗口大小调整所得到的应用窗口1160。
然后，将SurfaceView自带的Surface与新的Surface进行链接所得到的Surface链接于应用窗口1150中，以及将Activity中的各类视图的视图内容所共享的Surface保持于应用窗口1160中。最终，SurfaceView的视图内容和TextureView的视图内容可以显示在应用窗口1150上，而Activity中除TextureView外的其余视图的视图内容可以显示在应用窗口1160上。
综上所述，第一显示区域上用于呈现第一界面内容的Surface，不同于第二显示区域上用于呈现第二界面内容的Surface，如图11所示。
具体的，第二显示区域上用于呈现第二界面内容的Surface，可以是在折叠屏幕的整个显示区域上用于呈现界面内容的Surface中，如图11所示。

需要说明的是，处理单元可以是处理器或控制器，例如可以是中央处理器(central processing unit，CPU)、通用处理器、数字信号处理器(digital signal processor，DSP)、专用集成电路(application-specific integrated circuit，ASIC)、现场可编程门阵列(field programmable gate array，FPGA)或者其他可编程逻辑器件、晶体管逻辑器件、硬件部件或者其任意组合。其可以实现或执行结合本申请公开内容所描述的各种示例性的逻辑方框、模块和电路。处理单元也可以是实现计算功能的组合，例如包含一个或多个微处理器组合、DSP和微处理器的组合等。
在一些可能的实现中，显示装置1200还可以包括存储单元，用于存储显示装置1200所执行的计算机程序或者指令。
例如，该存储单元可以是存储器。
在一些可能的实现中，显示装置1200可以是芯片/芯片模组/处理器/硬件等。
具体实现时，显示装置1200用于执行如上述方法实施例中所描述的步骤。下面进行详细说明。
显示单元1210，用于响应于电子设备进入悬停状态，将目标应用的第一界面内容显示在电子设备的第一显示区域上，以及将目标应用的第二界面内容显示在电子设备的第二显示区域上；
其中，第一界面内容具有不向用户提供操作目标应用的功能，第二界面内容具有向用户提供操作目标应用的功能；或者，
第一界面内容具有不响应于用户对第一显示区域的触控事件的功能，第二界面内容具有响应于用户对第二显示区域的触控事件以操作目标应用的功能。
需要说明的是，结合上述“4)界面内容的分类”和“5)第一界面内容、第二界面内容”中的内容。第一界面内容可以为非操作类界面内容，第二界面内容可以为操作类界面内容。
其中，非操作类界面内容，可以具有不向用户提供操作目标应用的功能，或者不具有操作目标应用的功能。因此，用户不能操作/触控这类界面内容来操作目标应用。
例如，在图3中，该非操作类界面内容可以包括文字3306、动态图像3307等，而用户无法操作/触控这类界面内容来操作音乐播放应用。
其中，操作类界面内容，可以具有向用户提供操作目标应用的功能，或者具有操作目标应用的功能。因此，用户可以操作/触控这类界面内容来操作应用。
例如，在图3中，该操作类界面内容可以包括评论图标3301、分享图标3302、暂停/播放图标3303、上一曲图标3304、进度条3305等，而用户可以操作/触控这类界面内容来对该音乐播放应用所播放的音乐进行评论、分享、暂停/播放、切换、快进等操作。
另外，第一界面内容可以为非响应类界面内容，第二界面内容可以为响应类界面内容。
其中，非响应类界面内容，可以具有不响应于用户对的触控事件的功能。因此，当用户触控折叠屏幕以生成相应的触控事件时，这类界面内容不会响应于该触控事件，从而无法对目标应用进行相应的操作。
例如，在图3中，该非响应类界面内容可以包括文字3306、动态图像3307等，而这类视图内容无法响应于用户对折叠屏幕310的触控。
其中，响应类界面内容，可以具有响应于用户对的触控事件的功能。因此，当用户触控折叠屏幕以生成相应的触控事件时，这类界面内容会响应于该触控事件，从而对目标应用进行相应的操作。
例如，在图3中，该响应类界面内容可以包括评论图标3301、分享图标3302、暂停/播放图标3303、上一曲图标3304、进度条3305等，而这类界面内容会响应于用户对折叠屏幕310的触控，以便对该音乐播放应用所播放的音乐进行评论、分享、暂停/播放、切换、快进等操作。
可见，在电子设备进入悬停状态时，本申请实施例可以将目标应用的界面内容分成两类，即第一界面内容和第二界面内容，并将第一界面内容和第二界面内容分别显示在电子设备的两个显示区域上，即第一显示区域显示第一界面内容，而第二显示区域显示第二界面内容，从而实现将目标应用的界面内容进行视觉上的UI分离。
这样，当用户想要去操作该目标应用时，通过将该目标应用的界面内容进行分类以分别显示在不同显示区域上，如此可以将用于操作该目标应用的界面内容在用户更容易操作的显示区域上，以便有利于 避免因用户的触控而导致显示区域发生摆动以改变折叠角度等情况，提升用户的使用体验。
例如，在图3的(c)中，折叠屏幕310从未折叠状态进入悬停状态以使得折叠屏幕310的整个显示区域沿着折叠部位340分成显示区域3501和显示区域3502。
然后，将该音乐播放应用的界面内容进行分类，如评论图标3301、分享图标3302、暂停/播放图标3303、上一曲图标3304等视图内容为一类视图内容，而文字3306、动态图像3307等视图内容为另一类视图内容。其中，用户可以操作/触控评论图标3301、分享图标3302等这类视图内容来操作该音乐播放应用，但用户无法操作/触控文字3306等这类视图内容来操作该音乐播放应用。
最后，将评论图标3301、分享图标3302等这类视图内容显示在显示区域3502上的应用窗口3602中，而将文字3306、动态图像3307等这类视图内容显示在显示区域3501上的应用窗口3601中。
这样，当用户需要对该音乐播放应用所播放的音乐进行评论、分享时，用户只需去触控显示区域3502。相对于图3的(b)中需要去触控显示区域3501，用户触控显示区域3502会更加便捷和容易，能够避免折叠屏幕310发生折叠角度改变等情况，提升用户的使用体验。
需要说明的是，显示装置1200执行的各个操作的具体实现可以参见上述所示的方法实施例的相应描述，在此不再赘述。
2、其他一些实现方式
下面对所涉及的一些实现方式再进行说明，而其他未涉及的内容可以具体详见上述描述，对此不再赘述。
在一些可能的实现中，第一界面内容，包括以下至少一项：画布视图SurfaceView的视图内容、Activity中的纹理视图TextureView的视图内容；
第二界面内容，包括以下至少一项：Activity中的按钮Button的视图内容、Activity中的图像视图ImageView的视图内容、Activity中的视图View的视图内容。
需要说明的是，结合上述“5)第一界面内容、第二界面内容”的“②组成”中的内容，本申请实施例以Android系统为例，对第一界面内容和第二界面内容的组成进行说明时，第一界面内容可以包括以下至少一项：SurfaceView的视图内容、Activity中的TextureView的视图内容等；而第二界面内容可以包括以下至少一项：Activity中的Button的视图内容、Activity中的ImageView的视图内容、Activity中的View的视图内容等。
当然，第一界面内容和第二界面内容还可以包括其他视图内容，主要还是按照是否能操作应用，或者是否能响应对折叠屏幕的触控事件来进行划分，对此不作具体限制。
在一些可能的实现中，第一显示区域上用于呈现第一界面内容的画布Surface，不同于第二显示区域上用于呈现第二界面内容的Surface。
需要说明的是，结合上述“3、如何将第一界面内容和第二界面内容进行分屏显示”中的内容，当需要将第一界面内容显示在第一显示区域时，通常需要保证第一界面内容具有Surface，再通过该Surface来实现在该在第一显示区域上呈现第一界面内容。同理，当需要将第二界面内容显示在第二显示区域时，通常需要保证第二界面内容具有Surface，再通过该Surface来实现在该在第二显示区域上呈现第二界面内容。
然而，结合上述图11可知，由于本申请实施例第一显示区域上用于呈现第一界面内容的Surface可以是新创建的，也可以是链接得到的，因此最终第一显示区域上用于呈现第一界面内容的Surface，会不同于第二显示区域上用于呈现第二界面内容的Surface。
在一些可能的实现中，第一显示区域上用于呈现第一界面内容的Surface，为如下之一项：
第一界面内容自带的Surface、向第一界面内容新创建的Surface、第一界面内容自带的Surface与向第一界面内容中不具有自带的Surface的视图内容所新创建的Surface进行链接所得到的。
需要说明的是，结合上述“3、如何将第一界面内容和第二界面内容进行分屏显示”中的内容，由于第一界面内容可以由各类视图内容组成，而第一界面内容中可能存在自带独立的Surface的视图内容(如SurfaceView的视图内容)，也可能不存在自带独立的Surface的视图内容，因此，本申请实施例需要先判断是否向第一界面内容创建新的Surface。
若第一界面内容仅不具有自带的Surface，则本申请实施例可以向第一界面内容创建新的Surface。这样，本申请实施例可以得到第一显示区域上用于呈现第一界面内容的Surface，以便第一界面内容可以呈现在新创建的Surface上。
若第一界面内容具有自带的Surface以及不具有自带的Surface，则本申请实施例需要先向第一界面内容中不具有自带的Surface的视图内容创建新的Surface，再将不具有自带的Surface的视图内容呈现在新创建的Surface上，最后将第一界面内容自带的Surface与向第一界面内容不具有自带的Surface的视图 内容所新创建的Surface进行链接。这样，本申请实施例可以得到第一显示区域上用于呈现第一界面内容的Surface。
在一些可能的实现中，若第一界面内容包括SurfaceView的视图内容，则第一显示区域上用于呈现SurfaceView的视图内容的Surface，为SurfaceView自带的Surface；或者，
若第一界面内容包括Activity中的TextureView的视图内容，则第一显示区域上用于呈现TextureView的视图内容的Surface，为向SurfaceView新创建的Surface；或者，
若第一界面内容包括SurfaceView的视图内容、Activity中的TextureView的视图内容，则第一显示区域上用于呈现第一界面内容的Surface，是SurfaceView的Surface与TextureView的Surface进行链接所得到的。
需要说明的是，结合上述“3、如何将第一界面内容和第二界面内容进行分屏显示”中的内容，由于第一界面内容可以包括Activity中的TextureView的视图内容，可以SurfaceView的视图内容，可以SurfaceView的视图内容、Activity中的TextureView的视图内容，因此本申请实施例需要分情况来具体说明，以便实现确定第一显示区域上用于呈现第一界面内容的Surface。
在一些可能的实现中，第二显示区域上用于呈现第二界面内容的Surface，是在折叠屏幕的整个显示区域上用于呈现界面内容的Surface中。
需要说明的是，结合上述“3、如何将第一界面内容和第二界面内容进行分屏显示”中的内容，在图11中，由于第一界面内容的Surface与第二界面内容的Surface可以是共享界面内容的Surface，因此第二显示区域上用于呈现第二界面内容的Surface，可以是在界面内容的Surface中。这样，可以节省再去为第二显示区域上用于呈现第二界面内容的Surface进行创建，提供显示效率。
在一些可能的实现中，第一显示区域上用于显示第一界面内容的应用窗口是新创建的；
第二显示区域上用于显示第二界面内容的应用窗口，是对电子设备(折叠屏幕)处于非折叠状态下的整个显示区域上用于显示界面内容的应用窗口进行窗口大小调整所得到的。
需要说明的是，结合上述“3、如何将第一界面内容和第二界面内容进行分屏显示”中的内容，本申请实施例需要在第一显示区域上创建新的应用对应的应用窗口，再在该新创建的应用窗口中显示第一界面内容。此时，该新创建的应用窗口，可以称为第一显示区域上用于显示第一界面内容的应用窗口。
另外，在新创建完成该应用窗口时，本申请实施例需要创建了该新创建的应用窗口的SurfaceControl。
在一些可能的实现中，第一显示区域上用于呈现第一界面内容的Surface，链接于第一显示区域上用于显示第一界面内容的应用窗口。
需要说明的是，结合上述“3、如何将第一界面内容和第二界面内容进行分屏显示”中的内容，为了保证在该新创建的应用窗口中显示第一界面内容，本申请实施例需要将上述所得到的第一显示区域上用于呈现第一界面内容的Surface，链接于该新创建的应用窗口。
在一些可能的实现中，链接是采用如下步骤实现的：
将第一显示区域上用于呈现第一界面内容的Surface的画布控制SurfaceControl，重定父级到第一显示区域上用于显示第一界面内容的应用窗口的SurfaceControl。
需要说明的是，结合上述“3、如何将第一界面内容和第二界面内容进行分屏显示”中的内容，本申请实施例可以通过重定父级来实现将第一显示区域上用于呈现第一界面内容的Surface链接于该新创建的应用窗口。此时，第一显示区域上用于呈现第一界面内容的Surface的SurfaceControl的父级为该创建的应用窗口的SurfaceControl。
在一些可能的实现中，第一显示区域上用于呈现第一界面内容的Surface的SurfaceControl，可以是电子设备(折叠屏幕)处于非折叠状态下的整个显示区域上用于呈现界面内容的SurfaceControl下的子节点，或者新创建的。
需要说明的是，结合上述“3、如何将第一界面内容和第二界面内容进行分屏显示”中的内容，若第一界面内容包括SurfaceView的视图内容，则第一显示区域上用于呈现SurfaceView的视图内容的Surface的SurfaceControl，可以是界面内容的SurfaceControl下的子节点，如图10所示。
若第一界面内容包括Activity中的TextureView的视图内容，则第一显示区域上用于呈现SurfaceView的视图内容的Surface的SurfaceControl，可以是新创建的，如图8所示。
在一些可能的实现中，第一显示区域与第二显示区域具有相同的面积。
需要说明的是，结合上述“1、折叠屏幕的整个显示区域、第一显示区域和第二显示区域”中的内容，本申请实施例可以将折叠屏幕的整个显示区域沿着折叠部位被分成相同面积的两半。这样，第一显示区域与第二显示区域可以完全重叠。
四、一种电子设备的示例性说明
1、描述
下面介绍本申请实施例的一种电子设备的结构示意图，如图13所示。其中，电子设备1300，包括处理器1310、存储器1320和至少一个用于连接处理器1310、存储器1320的通信总线。
在一些可能的实现中，处理器1310可以是一个或多个中央处理器CPU。在处理器1310是一个CPU的情况下，该CPU可以是单核CPU，也可以是多核CPU。存储器1320包括但不限于是随机存储记忆体(random access memory,RAM)、只读存储器(read-only memory,ROM)、可擦除可编程只读存储器(erasable programmable read only memory,EPROM)或便携式只读存储器(compact disc read-only memory,CD-ROM)，并且存储器1320用于存储计算机程序或指令。
在一些可能的实现中，电子设备1300还包括通信接口，该通信接口用于接收和发送数据。
在一些可能的实现中，电子设备1300中的处理器1310用于执行存储器1320中存储的计算机程序或指令1321以实现如下步骤：
响应于电子设备1300进入悬停状态，将目标应用的第一界面内容显示在电子设备1300的第一显示区域上，以及将目标应用的第二界面内容显示在电子设备1300的第二显示区域上；
其中，第一界面内容具有不向用户提供操作目标应用的功能，第二界面内容具有向用户提供操作目标应用的功能；或者，
第一界面内容具有不响应于用户对第一显示区域的触控事件的功能，第二界面内容具有响应于用户对第二显示区域的触控事件以操作目标应用的功能。
需要说明的是，结合上述“4)界面内容的分类”和“5)第一界面内容、第二界面内容”中的内容。第一界面内容可以为非操作类界面内容，第二界面内容可以为操作类界面内容。
其中，非操作类界面内容，可以具有不向用户提供操作目标应用的功能，或者不具有操作目标应用的功能。因此，用户不能操作/触控这类界面内容来操作目标应用。
例如，在图3中，该非操作类界面内容可以包括文字3306、动态图像3307等，而用户无法操作/触控这类界面内容来操作音乐播放应用。
其中，操作类界面内容，可以具有向用户提供操作目标应用的功能，或者具有操作目标应用的功能。因此，用户可以操作/触控这类界面内容来操作应用。
例如，在图3中，该操作类界面内容可以包括评论图标3301、分享图标3302、暂停/播放图标3303、上一曲图标3304、进度条3305等，而用户可以操作/触控这类界面内容来对该音乐播放应用所播放的音乐进行评论、分享、暂停/播放、切换、快进等操作。
另外，第一界面内容可以为非响应类界面内容，第二界面内容可以为响应类界面内容。
其中，非响应类界面内容，可以具有不响应于用户对的触控事件的功能。因此，当用户触控折叠屏幕以生成相应的触控事件时，这类界面内容不会响应于该触控事件，从而无法对目标应用进行相应的操作。
例如，在图3中，该非响应类界面内容可以包括文字3306、动态图像3307等，而这类视图内容无法响应于用户对折叠屏幕310的触控。
其中，响应类界面内容，可以具有响应于用户对的触控事件的功能。因此，当用户触控折叠屏幕以生成相应的触控事件时，这类界面内容会响应于该触控事件，从而对目标应用进行相应的操作。
例如，在图3中，该响应类界面内容可以包括评论图标3301、分享图标3302、暂停/播放图标3303、上一曲图标3304、进度条3305等，而这类界面内容会响应于用户对折叠屏幕310的触控，以便对该音乐播放应用所播放的音乐进行评论、分享、暂停/播放、切换、快进等操作。
可见，在电子设备进入悬停状态时，本申请实施例可以将目标应用的界面内容分成两类，即第一界面内容和第二界面内容，并将该两类视图类型分别显示在电子设备两个显示区域上，即第一显示区域显示第一界面内容，而第二显示区域显示第二界面内容，从而实现将应用的界面内容进行视觉上的UI分离。
这样，当用户想要去操作该目标应用时，通过将该目标应用的界面内容进行分类以分别显示在不同显示区域上，如此可以将用于操作该目标应用的界面内容显示在用户更容易操作的显示区域上，以便有利于避免因用户的触控而导致显示区域发生摆动以改变折叠角度等情况，提升用户的使用体验。
例如，在图3的(c)中，折叠屏幕310从未折叠状态进入悬停状态以使得折叠屏幕310的整个显示区域沿着折叠部位340分成显示区域3501和显示区域3502。
然后，将该音乐播放应用的界面内容进行分类，如评论图标3301、分享图标3302、暂停/播放图标3303、上一曲图标3304等视图内容为一类视图内容，而文字3306、动态图像3307等视图内容为另一类视图内容。其中，用户可以操作/触控评论图标3301、分享图标3302等这类视图内容来操作该音乐播放应 用，但用户无法操作/触控文字3306等这类视图内容来操作该音乐播放应用。
最后，将评论图标3301、分享图标3302等这类视图内容显示在显示区域3502上的应用窗口3602中，而将文字3306、动态图像3307等这类视图内容显示在显示区域3501上的应用窗口3601中。
这样，当用户需要对该音乐播放应用所播放的音乐进行评论、分享时，用户只需去触控显示区域3502。相对于图3的(b)中需要去触控显示区域3501，用户触控显示区域3502会更加便捷和容易，能够避免折叠屏幕310发生折叠角度改变等情况，提升用户的使用体验。
需要说明的是，电子设备1300执行的各个操作的具体实现可以参见上述所示的方法实施例的相应描述，在此不再赘述。
2、其他一些可能的实现方式

在一些可能的实现中，第一界面内容，包括以下至少一项：画布视图SurfaceView的视图内容、Activity中的纹理视图TextureView的视图内容；
第二界面内容，包括以下至少一项：Activity中的按钮Button的视图内容、Activity中的图像视图ImageView的视图内容、Activity中的视图View的视图内容。
需要说明的是，结合上述“5)第一界面内容、第二界面内容”的“②组成”中的内容，本申请实施例以Android系统为例，对第一界面内容和第二界面内容的组成进行说明时，第一界面内容可以包括以下至少一项：SurfaceView的视图内容、Activity中的TextureView的视图内容等；而第二界面内容可以包括以下至少一项：Activity中的Button的视图内容、Activity中的ImageView的视图内容、Activity中的View的视图内容等。
当然，第一界面内容和第二界面内容还可以包括其他视图内容，主要还是按照是否能操作应用，或者是否能响应对折叠屏幕的触控事件来进行划分，对此不作具体限制。
在一些可能的实现中，第一显示区域上用于呈现第一界面内容的画布Surface，不同于第二显示区域上用于呈现第二界面内容的Surface。

然而，结合上述图11可知，由于本申请实施例第一显示区域上用于呈现第一界面内容的Surface可以是新创建的，也可以是链接得到的，因此最终第一显示区域上用于呈现第一界面内容的Surface，会不同于第二显示区域上用于呈现第二界面内容的Surface。
在一些可能的实现中，第一显示区域上用于呈现第一界面内容的Surface，为如下之一项：
第一界面内容自带的Surface、向第一界面内容新创建的Surface、第一界面内容自带的Surface与向第一界面内容中不具有自带的Surface的视图内容所新创建的Surface进行链接所得到的。
需要说明的是，结合上述“3、如何将第一界面内容和第二界面内容进行分屏显示”中的内容，由于第一界面内容可以由各类视图内容组成，而第一界面内容中可能存在自带独立的Surface的视图内容(如SurfaceView的视图内容)，也可能不存在自带独立的Surface的视图内容，因此，本申请实施例需要先判断是否向第一界面内容创建新的Surface。

若第一界面内容具有自带的Surface以及不具有自带的Surface，则本申请实施例需要先向第一界面内容中不具有自带的Surface的视图内容创建新的Surface，再将不具有自带的Surface的视图内容呈现在新创建的Surface上，最后将第一界面内容自带的Surface与向第一界面内容不具有自带的Surface的视图内容所新创建的Surface进行链接。这样，本申请实施例可以得到第一显示区域上用于呈现第一界面内容的Surface。
在一些可能的实现中，若第一界面内容包括SurfaceView的视图内容，则第一显示区域上用于呈现SurfaceView的视图内容的Surface，为SurfaceView自带的Surface；或者，
若第一界面内容包括Activity中的TextureView的视图内容，则第一显示区域上用于呈现TextureView的视图内容的Surface，为向SurfaceView新创建的Surface；或者，
若第一界面内容包括SurfaceView的视图内容、Activity中的TextureView的视图内容，则第一显示区域上用于呈现第一界面内容的Surface，是SurfaceView的Surface与TextureView的Surface进行链接所得到的。
需要说明的是，结合上述“3、如何将第一界面内容和第二界面内容进行分屏显示”中的内容，由于第一界面内容可以包括Activity中的TextureView的视图内容，可以SurfaceView的视图内容，可以SurfaceView的视图内容、Activity中的TextureView的视图内容，因此本申请实施例需要分情况来具体说明，以便实现确定第一显示区域上用于呈现第一界面内容的Surface。
在一些可能的实现中，第二显示区域上用于呈现第二界面内容的Surface，是在折叠屏幕的整个显示区域上用于呈现界面内容的Surface中。
需要说明的是，结合上述“3、如何将第一界面内容和第二界面内容进行分屏显示”中的内容，在图11中，由于第一界面内容的Surface与第二界面内容的Surface可以是共享界面内容的Surface，因此第二显示区域上用于呈现第二界面内容的Surface，可以是在界面内容的Surface中。这样，可以节省再去为第二显示区域上用于呈现第二界面内容的Surface进行创建，提供显示效率。
在一些可能的实现中，第一显示区域上用于显示第一界面内容的应用窗口是新创建的；
第二显示区域上用于显示第二界面内容的应用窗口，是对电子设备(折叠屏幕)处于非折叠状态下的整个显示区域上用于显示界面内容的应用窗口进行窗口大小调整所得到的。
需要说明的是，结合上述“3、如何将第一界面内容和第二界面内容进行分屏显示”中的内容，本申请实施例需要在第一显示区域上创建新的应用对应的应用窗口，再在该新创建的应用窗口中显示第一界面内容。此时，该新创建的应用窗口，可以称为第一显示区域上用于显示第一界面内容的应用窗口。
另外，在新创建完成该应用窗口时，本申请实施例需要创建了该新创建的应用窗口的SurfaceControl。
在一些可能的实现中，第一显示区域上用于呈现第一界面内容的Surface，链接于第一显示区域上用于显示第一界面内容的应用窗口。
需要说明的是，结合上述“3、如何将第一界面内容和第二界面内容进行分屏显示”中的内容，为了保证在该新创建的应用窗口中显示第一界面内容，本申请实施例需要将上述所得到的第一显示区域上用于呈现第一界面内容的Surface，链接于该新创建的应用窗口。
在一些可能的实现中，链接是采用如下步骤实现的：
将第一显示区域上用于呈现第一界面内容的Surface的画布控制SurfaceControl，重定父级到第一显示区域上用于显示第一界面内容的应用窗口的SurfaceControl。
需要说明的是，结合上述“3、如何将第一界面内容和第二界面内容进行分屏显示”中的内容，本申请实施例可以通过重定父级来实现将第一显示区域上用于呈现第一界面内容的Surface链接于该新创建的应用窗口。此时，第一显示区域上用于呈现第一界面内容的Surface的SurfaceControl的父级为该创建的应用窗口的SurfaceControl。
在一些可能的实现中，第一显示区域上用于呈现第一界面内容的Surface的SurfaceControl，可以是电子设备(折叠屏幕)处于非折叠状态下的整个显示区域上用于呈现界面内容的SurfaceControl下的子节点，或者新创建的。
需要说明的是，结合上述“3、如何将第一界面内容和第二界面内容进行分屏显示”中的内容，若第一界面内容包括SurfaceView的视图内容，则第一显示区域上用于呈现SurfaceView的视图内容的Surface的SurfaceControl，可以是界面内容的SurfaceControl下的子节点，如图10所示。
