在一些实施例中，本申请所指的是否存在flag可以理解为对flag的值进行判断。例如，若flag为1，判断存在，若flag为0，判断不存在。又例如，若flag为0，判断存在，若flag为1，判断不存在。本申请对此不做限定。
基于前述实施例的描述，窗口界面可以对应多个Activity。窗口界面的Activity被调用过程中，相应APP的Window state被更新，一些实施例中，在更新Window state的实施过程中，可以更新为前述的至少一个flag。基于此，WMS可以通过遍历窗口界面的Window state是否包含flag，确定窗口界面是否包含安全标志位。若相应Activity对应的Window state包含前述任一flag，则指示该APP当前窗口界面包含安全标志位，第一设备100则向第二设备200发送安全保护指令。

或者其它操作系统的设备。
图2C示出了第二设备200的示例性架构示意图。第二设备200可以包括处理器210，存储器220，无线通信模块230，显示屏240以及电源250等。
可以理解的是，本申请示意的结构并不构成对第二设备200的具体限定。在本申请另一些实施例中，第二设备200可以包括比图示更多或更少的部件，或者组合某些部件，或者拆分某些部件，或者不同的部件布置。图示的部件可以以硬件，软件或软件和硬件的组合实现。
本实施例中，处理器210所包含的硬件和软件以及各硬件和软件的功能，与处理器110类似。本申请此处不再详述。处理器210可以用于调用显示屏240显示来自于第一设备100的投屏界面和安全界面等。一些实施例中，处理器210还可以用于生成操作指令，该操作指令用于指示用户在第一设备100端对APP进行操作。
无线通信模块230提供的通信的解决方案与无线通信模块160类似，此处不再详述。无线通信模块230提供的通信的解决方案可使得第二设备200与第一设备100通信，以使第二设备200与第一设备100之间实现视频流以及指令的交互功能。例如，无线通信模块230实现第二设备200接收来自于第一设备100的待投屏的视频流的功能。

电源240可以用于为处理器210，存储器220，显示屏240等供电。
本申请实施例涉及的用于实现显示功能的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受形式之间的转换。应用程序的用户界面是通过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，界面源代码在终端设备上经过解析，渲染，最终呈现为 用户可以识别的内容，比如视频、图片、文字、按钮等控件。控件(control)也称为部件(widget)，是用户界面的基本元素，典型的控件有工具栏(toolbar)、菜单栏(menu bar)、文本框(text box)、按钮(button)、滚动条(scrollbar)、图片和文本。界面中的控件的属性和内容是通过标签或者节点来定义的，比如XML通过<Textview>、<ImgView>、<VideoView>等节点来规定界面所包含的控件。一个节点对应界面中一个控件或属性，节点经过解析和渲染之后呈现为用户可视的内容。此外，很多应用程序，比如混合应用(hybrid application)的界面中通常还包含有网页。网页，也称为页面，可以理解为内嵌在应用程序界面中的一个特殊的控件，网页是通过特定计算机语言编写的源代码，例如超文本标记语言(hyper text markup language，HTML)，层叠样式表(cascading style sheets，CSS)，java脚本(JavaScript，JS)等，网页源代码可以由浏览器或与浏览器功能类似的网页显示组件加载和显示为用户可识别的内容。网页所包含的具体内容也是通过网页源代码中的标签或者节点来定义的，比如HTML通过<p>、<img>、<video>、<canvas>来定义网页的元素和属性。
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一个图标、窗口、控件等界面元素，其中控件可以包括图标、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。
需要指出的是，一种典型的基于投屏场景的安全保护机制中，第一设备100向第二设备200投屏，通常以display为单位进行投屏，第二设备200以窗口界面为单位显示安全界面。基于此，若第一设备100投屏的display中包含至少两个窗口界面，第二设备200可以对应显示至少两个投屏界面。当该至少两个窗口界面中任一窗口界面需要安全保护，第二设备200均以窗口界面为单位显示安全界面，从而使得该至少两个投屏界面均显示安全界面或黑屏(此时第一设备的display数据不会被传递到第二设备)。这样，导致用户对无安全需求的投屏界面也无法正常操作，用户体验较差。
为了解决上述问题，本申请实施例提供了一种显示方法及电子设备。如图4A所示，本申请实施例涉及的显示方法包括：第一设备接收用户输入的投屏指令。响应于该投屏指令，第一设备将第一窗口界面投屏到第二设备，相应的，第二设备显示第一窗口界面的投屏界面。进而，第一设备响应指令运行第二窗口界面之后，将第二窗口界面投屏至第二设备(此指令来源于第二设备，例如，当第一窗口界面为主界面时，该指令为双击运行应用的操作)。第一设备遍历Window state后确认第二窗口界面包含安全标志位，发送第二窗口的任务号和安全保护指令。第二设备显示第一窗口界面的投屏界面和安全界面(安全界面用于替代原第二窗口界面显示)。
其中，第一设备遍历Window state的触发可以是周期性触发，还有可能是Activity在栈中的位置发生变化触发，还有可能是栈顶的Activity发生变化触发。
基于此，图4A示意的实施场景中，第一设备启动第二窗口界面之后，第二窗口界面响应启动指令呈现的第二窗口界面的Activity对应的flag即为1。例如，第二窗口界面是银行APP的登录界面，第二窗口启动之后，即触发安全键盘。这样，第一设备在投屏之前，即刻确定第二窗口包含安全标志，进而，第一设备将第二窗口的任务号和安全保护指令发送到第二设备，以使第二设备显示第一窗口界面的投屏界面和安全界面。
另一些实施例中，本申请实施例还提供了另一种示例性的显示方法。如图4A所示，本实施例中，第一设备接收用户输入的投屏指令。响应于该投屏指令，第一设备将第一窗口界面投屏到第二设备。第一设备响应指令运行第二窗口界面之后，在第一个遍历周期内确定第二窗口界面中不包含安全标志位，进而，将第二窗口界面投屏至第二设备。进而，第一设备在之后的遍历周期中，检测到第二窗口界面包含安全标志位，然后，第一设备向第二设备发送第二窗口界面的任务号和安全保护指令。相应的。第二设备显示第一窗口界面的投屏界面和安全界面。
图4B示意的实施场景中，第一设备启动第二窗口界面之后，当前启动的第二窗口界面的内容无安全需求，相应的，第二窗口界面当前的Window state的flag置0。那么，第一设备可以将该第二窗口界面的内容投屏到第二设备，以使第二设备显示第一窗口界面的投屏界面和第二窗口界面的投屏界面。而响应于用户的触发，第二窗口界面的变更，从而触发变更后界面的Activity变化，使得变更后的第二窗口界面存在安全需求，相应Window state的flag置1。进而，第一设备能够确定此时的第二窗口界面包含安全标志位，第一设备触发第二设备将第二窗口界面显示为安全界面，以使第二设备显示第一窗口界面的投屏界面和安全界面。
例如，第二窗口界面启动后，显示的是钱包APP的主界面。钱包APP的主界面例如无安全需求的照片，那么，第一设备将钱包APP投屏到第二设备。第二设备可以显示钱包APP主界面的投屏界面。进而，响应于用户的触发，第二窗口界面进入钱包APP的支付界面。此时，第二窗口界面包含支付密码输入控件，为有安全需求的界面。第一设备在检测到安全标志位之后，向第二设备发送第二窗口界面(钱包APP的界面)任务号及安全保护指令，以使第二设备将第二窗口界面的投屏界面显示为安全界面。
进一步的，上述图4A或图4B示意的实施例中，若第二窗口界面进一步响应用户的操作指令更新了所显示的内容，且相应的内容无安全需求，相应Window state的flag置0。那么，第一设备在周期性遍历Window state的过程中，能够基于该Window state确定第二窗口界面无安全标识位，进而，第一设备可以将更新后的第二窗口界面投屏到第二设备。相对应的，第二设备隐藏安全界面，以及显示第二窗口界面更新后的投屏界面。
根据前述对投屏的描述可知，第一设备向第二设备投屏的内容是第一设备display内包含的窗口界面，即，第一窗口界面和第二窗口界面是第一设备display内包含的窗口桌面。应理解，若第一设备display内还包含第三窗口界面和第四窗口界面等，第一设备还应当检测第三窗口界面和第四窗口界面是否包含安全标志位，之后，第一设备按照检测结果向第二设备发送第三窗口界面和第四窗口界面的投屏信息。此处不赘述。此外，本申请实施例中，第一设备的display每更新一次，第一设备执行一次投屏。其中，display内的窗口界面增加、减少、以及任意窗口界面的更改，均认为是display更新。
需要说明的是，第一设备向第二设备投屏，可以实现为第一设备与第二设备建立网络连接后，第一设备将待显示的界面以视频流的方式发送到第二设备。之后，第二设备可以基于第一设备发送的参数信息(例如窗口界面的大小、窗口界面的位置、窗口界面间的相对位置)对视频流进行切割，进而，以窗口的形式分别显示第一设备投屏的各个界面。基于此，在投屏的实施场景中，WMS配置用于平铺显示待投屏窗口界面的display，以及AMS为每个待投屏窗口界面添加taskID，以便于第一设备对应各个待投屏窗口界面生成视频 流，并标识各个待投屏窗口界面。
需要说明的是，display中包含第一设备正在运行的全部APP的窗口界面，而其中的待投屏窗口界面可以是display中的全部窗口界面，也可以是display中的部分窗口界面。
在一些实施方式中，第一设备在投屏之前确定各个窗口界面是否具备安全需求，进而，第一设备根据检测结果，将每个窗口界面的taskID以及该窗口界面的投屏信息发送到第二设备。第二设备基于taskID显示安全界面和包含窗口界面内容的投屏界面，其中，安全界面是有安全需求的窗口界面的投屏界面。这样，第二设备既能够安全显示有安全要求的界面，也能够确保用户对无安全要求的界面正常操作。
为了便于理解，本申请以下实施例将以具有图2A和图2B所示结构的手机为例，以具有图2C所示结构的笔记本电脑为例，结合附图对本申请实施例提供的投屏场景下的显示方法进行具体阐述。
本申请实施例可以将实际实施过程划分为以下三个阶段：启动投屏功能的阶段、安全需求场景中的显示阶段、以及对安全界面操作之后的显示阶段，以下结合该三个阶段对显示方法的实施例进行介绍。
启动投屏功能的阶段：
本申请实施例中，手机与笔记本电脑可以通过各自的无线通信模块建立通信连接。在接收到用户输入的开启投屏功能的指令之后，手机例如可以基于无线直连(WiFi Direct)技术，向笔记本电脑发送需要投屏的视频流，以实现投屏功能。一些实施例中，手机与笔记本电脑例如可以通过各自的NFC模块或者蓝牙模块建立通信连接。在接收到用户点击开启“多设备协同”的指令之后，手机的投屏功能开启。在手机与笔记本电脑的距离小于或者等于通信传输距离的场景下，手机向笔记本电脑投屏第一组窗口界面。满足前述投屏的场景需求，则认为手机接收到投屏指令。此处不详述。手机向笔记本电脑投屏第一组窗口界面相关的显示界面如图5A至5C-2所示。
可以理解的是，前述手机与笔记本电脑建立通信连接的模块，以及开启手机投屏功能的接口，均是示意性描述，不构成对本申请实施例的限制。在另一些实施例中，手机与笔记本电脑还可以基于其他通信模块建立连接。另外，开启手机投屏功能的接口，可以根据手机的型号以及手机操作系统版本的不同而不同，此处不限制。
如图5A所示，图5A示意的GUI51是手机投屏到笔记本电脑之后，笔记本电脑的第一种示例性显示界面。其中，GUI51包括投屏界面510，投屏界面510是手机桌面的投屏界面，包括手机桌面中各个界面元素的图像，例如，图库、邮箱、钱包等。
图5A对应的实施例中，在接收到投屏指令期间，无论手机的显示屏正在显示的是什么界面，以及无论手机前台运行什么APP，手机调用无线通信模块，将手机桌面的视频流发送到笔记本电脑。进而，笔记本电脑解码相应视频流，以及显示该视频流对应的投屏界面510。此时，手机运行的APP可选地均以自由悬浮窗的形式运行。
一些实施例中，投屏界面的宽高比可以与窗口界面的宽高比相同。投屏界面的尺寸取决于第二设备屏幕的尺寸。例如，第二设备屏幕的尺寸是宽285.7毫米(mm)*高214.3mm，投屏界面的尺寸可以是宽110mm*高210mm。第二设备屏幕的尺寸是宽1456.4mm*高850.9mm，投屏界面的尺寸可以是宽450mm*高800mm。
如图5B所示，图5B示意的GUI52是手机执行投屏过程中，手机的一种示例性显示界 面，图5B示意的GUI53是手机投屏到笔记本电脑之后，笔记本电脑的第二种示例性显示界面。其中，GUI52例如是手机正在运行的图库APP的显示界面，GUI52中包括图像521和图像522。GUI53包括投屏界面530，投屏界面530是GUI52的投屏界面，投屏界面530包括图像521的投屏图像531，和图像532的投屏图像532。
图5B对应的实施例中，在接收到投屏指令期间，手机正在显示窗口界面。进而，WMS遍历该窗口界面对应的Activity是否包含flag。若该窗口界面对应的Activity不包含flag，手机的GPU可以渲染手机当前正在显示的界面视频流。之后，手机调用无线通信模块，将手机正在显示的界面的视频流发送到笔记本电脑。进而，笔记本电脑解码相应视频流，以及显示该视频流对应的投屏界面530。
另一些实施例中，若该窗口界面对应的Activity包含flag，手机可以向笔记本电脑投屏手机的桌面。相应的，笔记本电脑的GUI可以如GUI51所示。在手机接收到用户的操作，且手机更新窗口界面之后，手机可以将更新后窗口界面投屏到笔记本电脑。详见下述相关实施例的描述，此处不详述。
另一些实施例中，若手机未显示任何APP的界面，手机向笔记本电脑投屏手机的桌面。相应的，笔记本电脑的GUI可以如GUI51所示。
如图5C所示，图5C示意的GUI54是手机执行投屏过程中，手机的另一种示例性显示界面，图5C示意的GUI55是手机投屏到笔记本电脑之后，笔记本电脑的第三种示例性显示界面。其中，GUI54例如是手机正在运行且有安全需求的窗口界面的显示界面。GUI54的一种示例性显示界面详见图5C-2所示，此处不详述。GUI55包括投屏界面551和投屏界面552。其中，投屏界面551是手机正在运行且无安全需求的窗口界面的投屏界面，投屏界面552是手机桌面的投屏界面。
图5C对应的实施例中，在接收到投屏指令期间，手机例如正在运行若干个APP。本实施例中，手机可以分别检测该若干个APP正在运行的窗口界面是否包含安全标志位，之后，手机可以将其中不包含安全标志位的窗口界面以及手机的桌面投屏到笔记本电脑，且在手机的显示屏堆叠显示其中包含安全标志位的窗口界面(如图5C中的GUI54所示)，以便于用户执行下一步操作。而笔记本电脑显示无安全需求的窗口界面的投屏界面(如图5C中的GUI55所示)。
示例性的，在接收到投屏指令期间，手机例如正在运行邮箱、钱包和图库三个APP，其中，邮箱当前的窗口界面例如是登陆界面，钱包当前的窗口界面例如是管理银行卡的界面。进而，WMS遍历该三个窗口界面对应的Activity，以确定每个Activity中是否包含flag。例如，WMS确定邮箱当前窗口界面对应的Activity中包含第一flag，钱包当前窗口界面对应的Activity中包含第二flag，图库当前窗口界面对应的Activity中不包含flag。之后，WMS可以将遍历的结果上报DMS。DMS基于遍历结果配置手机的display以及各个窗口界面的显示策略。所述display的显示界面如图5C-1所示。
如图5C-1所示，图5C-1示意的display50包括display501和display502。其中，display501部署在手机的显示屏，是用户可见的display。display502是display501的扩展display，是用户不可见的虚拟display。本实施例中，手机的桌面和图库的窗口界面无安全需求，所以，手机可以将桌面和图库的窗口界面投屏到笔记本电脑。基于此，AMS可以为手机的桌面和图库的窗口界面分别配置taskID。例如，AMS为手机的桌面配置task  0，AMS为图库的窗口界面配置task 1。且，DMS可以配置手机的桌面在display501呈现，以及配置图库的窗口界面在display502呈现。进而，手机的GPU可以渲染手机的桌面和图库的窗口界面的视频流。之后，手机调用无线通信模块，将task 0和手机桌面的视频流，以及task 1和图库的窗口界面的视频流发送到笔记本电脑。进而，笔记本电脑解码相应视频流，以及分割解码得到的图像，然后显示图5C中的GUI55。GUI55中投屏界面551例如是手机桌面的投屏界面，投屏界面551对应task 0，投屏界面552例如是图库的窗口界面的投屏界面，投屏界面552对应task 1。
进一步的，邮箱的窗口界面和钱包的窗口界面是具备安全需求的界面，即使投屏到笔记本电脑，笔记本电脑也不被允许显示该两窗口界面的内容。基于此，手机可以不将该两个窗口界面投屏到笔记本电脑，而是在手机的显示屏显示该两个窗口界面。其中，DMS可以基于WMS的遍历结果，配置该两窗口界面在手机显示屏的显示策略，之后，DMS可以通过显示驱动和表面管理器该两个窗口界面在手机的显示屏显示。该两个窗口界面的显示界面如图5C-2所示。
图5C-2示意的GUI56是GUI54的一种示例性显示界面。GUI56是窗口界面561的图像和窗口界面562的图像的显示界面，窗口界面561的图像和窗口界面562的图像堆叠显示，且，GUI56的底端还包括删除图标563等。窗口界面561例如是邮箱的登录界面，窗口界面561例如是钱包的管理银行卡界面。在接收到用户点击删除图标563的指令后，AMS结束邮箱的进程和钱包的进程。在接收到用户点击窗口界面561的图像的指令后，DMS控制邮箱的登录界面在手机显示屏的最前端显示，以便于用户基于输入邮箱的账号和密码。同理，在接收到用户点击窗口界面562的图像的指令后，DMS控制钱包的管理银行卡界面在手机显示屏的最前端显示，以便于用户执行下一步操作，例如支付操作等。此处不再详述。
一些实施例中，手机可以在将图5C-1示意的display50投屏到笔记本电脑之后，显示GUI56。
进一步的，手机将display50投屏到笔记本电脑之后，手机显示GUI56以及其他后续显示，均已经触发窗口界面的更新，相应的，触发display50更新为其他display。之后，WMS遍历更新后的display中的窗口界面是否包含安全标志位，进而，手机可以根据检测结果，对更新后的display进行投屏。
采用本实现方式，手机在接收到投屏指令之后，无论当前运行APP的窗口界面是否有安全需求，手机均选择一组无安全需求的界面，作为第一组窗口界面投屏到笔记本电脑。这样，既能向笔记本电脑投屏至少一个可操作界面，使得用户能够继续操作，又能够确保有安全需求的窗口界面的安全性，并且能够节省传输资源。
需要说明的是，在一些可能的实施方案中，手机可以在本阶段将安全界面发送到笔记本电脑。相应的，笔记本电脑可以将安全界面存储在本地，以及在接收到来自于手机的安全保护指令之后，将安全保护指令指示投屏界面显示为该安全界面。
图6示意了一种安全界面60。安全界面60包含图标61和图标62。图标61例如显示以下信息：“需要在手机端操作，以保护您的隐私”。图标62例如显示以下信息：“在手机上显示该应用”，图标62可选的接收用户在电脑上的点击，通过例如Miracst UIBC(user input back control，用户输入反向控制)协议发送至手机侧。安全界面60的背景颜色可以纯色，例如黑色。另一些实施例中，为了优化用户的观感，安全界面60的背景可以是高斯模糊 化的手机壁纸。
在一些实施方案中，安全界面的背景可选地由电脑侧产生。在一些实施方案中，为了更好地给用户在手机和电脑上的体验一致性，安全界面可选地由手机侧产生，例如手机对其壁纸进行高斯模糊处理后发送至电脑，电脑存储该处理后的壁纸。电脑在接收到手机发送的显示安全界面的时候从本地读取该壁纸并显示。可以理解的是，当手机侧检测到本机壁纸更换，手机会执行上面的操作以使得电脑侧和安全界面的背景能够和手机侧的壁纸保持一致。
可以理解的是，图6仅是示意性描述，对本申请实施例不构成限制。在另一些实施例中，安全界面还可以包含其他信息。另外，安全界面包含的信息可以灵活设置。此处不再详述。
出现安全需求界面的显示阶段：
在手机向笔记本电脑投屏第一组窗口界面之后，用户在手机端继续操作或者在笔记本电脑端继续操作，均可能触发显示具备安全需求的界面。以下从用户触发手机和用户触发笔记本电脑两种的场景的角度，对显示安全界面的实施例进行描述。
场景一：用户在笔记本电脑端操作
本申请实施例中，笔记本电脑接收到用户点击投屏界面的指令后，该笔记本电脑可以生成第一操作指令，该第一操作指令与第一APP关联。第一APP是用户所点击图像指示的APP。之后，笔记本电脑基于WiFi Direct技术将该第一操作指令发送到手机。手机响应该第一操作指令，对第一APP执行操作，从而触发第一APP所显示窗口界面更改，进而，使得手机的display更新。进而，手机对应更新后的display执行安全标志位检测及再次投屏的操作，从而使得笔记本电脑显示用户触发的APP的投屏界面，实现用户基于投屏界面对手机的APP进行操作的功能。图7中的(a)至(b)示意了场景一中的一种示例性显示方法。图8中的(a)至(b)示意了随图7示意的实施过程，手机端display的示意性变化过程。
如图7中的(a)所示，GUI70是手机将图8中的(a)示意的display80投屏到笔记本电脑之后，笔记本电脑的显示界面。GUI70包括投屏界面701和投屏界面702，投屏界面701例如是手机桌面的投屏界面，包括邮箱和备忘录等APP的图像。投屏界面702例如是备忘录的窗口界面的投屏界面。其中，投屏界面701对应标识task 0，投屏界面702对应标识task 1。在接收到用户点击邮箱的指令后，笔记本电脑生成第一操作指令，该第一操作指令用于触发手机运行邮箱APP(前述第一APP的实例)。之后，笔记本电脑将第一操作指令发送到手机。手机响应第一操作指令运行邮箱APP，从而启动邮箱的登录界面。邮箱的登录界面如图12所示，此处不详述。进而，手机端的display80更新为图8中的(b)示意的display81。之后，手机将display81投屏到笔记本电脑，使得笔记本电脑的GUI70更新为图7中的(b)示意的GUI71。
其中，笔记本电脑接收用户的点击操作之后，可以识别用户点击的图像对应的第一APP标识，第一APP标识用于指示第一APP。之后，笔记本电脑生成第一操作指令，该第一操作指令中包含第一APP标识。进而，手机可以根据第一APP标识确定第一APP。第一APP标识例如可以是第一APP的名称。
图7中的(b)示意的GUI71是手机将图8中的(b)示意的display81投屏到笔记本 电脑之后，笔记本电脑的显示界面。GUI71包括投屏界面711、投屏界面712和投屏界面713。投屏界面711对应标识task 0，投屏界面712对应标识task 1，投屏界面713对应标识task 2。其中，投屏界面711例如是手机桌面的投屏界面，投屏界面711与GUI70中的投屏界面701相同。投屏界面712例如是备忘录的窗口界面的投屏界面，投屏界面712与GUI70中的投屏界面702相同。投屏界面713例如是邮箱的窗口界面的投屏界面，投屏界面713是如图6所示的安全界面。此处不详述。
如图8中的(a)所示，display80中包括窗口界面71和窗口界面72。窗口界面71是手机桌面，投屏得到GUI70中的投屏界面701。窗口界面72是备忘录的窗口界面，投屏得到GUI70中的投屏界面702。由于显示窗口界面71和窗口界面72，WMS以手机显示屏的宽度为单位扩展出一个虚拟display，使得display80包括display801和display802，display801是手机的显示屏对应的显示区域，display802是虚拟display，display802的宽度可以与display801的宽度相同。进而，WMS将窗口界面71部署在display801内显示，将窗口界面72部署在display802内显示。另外，为了便于识别窗口界面71和窗口界面72，AMS为窗口界面71设置标识task 0，以及为窗口界面72设置标识task 1。进而，本实施例中，手机在确定窗口界面71和窗口界面72均无安全需求之后，将task 0、task 1以及窗口界面71和窗口界面72的视频流发送到笔记本电脑，使得笔记本电脑呈现GUI70。
进一步的，手机响应第一操作指令打开显示邮箱的登录界面之后，手机的display在display80的基础上增加了一个窗口界面，进而，display80更新为display81。
如图8中的(b)所示，display81是投屏得到GUI71的示意性显示界面。display81中包括窗口界面71、窗口界面72和窗口界面73。窗口界面71投屏得到GUI71中的投屏界面711。窗口界面72投屏得到GUI71中的投屏界面712。窗口界面73投屏得到GUI71中的投屏界面713。本实施例中，为了容纳窗口界面71、窗口界面72和窗口界面73，DMS基于手机的显示屏扩展出虚拟display，以得到display81。display81包括display811和display812。display811是手机的显示屏，display812是虚拟display，display812的宽度可以是display811宽度的两倍。进而，WMS将窗口界面71部署在display811内显示，并为窗口界面71设置标识task 0，以及将窗口界面72和窗口界面73部署在display812内平铺显示，并为窗口界面72设置标识task 1，为窗口界面73设置标识task 2。
一些实施例中，display81可以是手机对display80继续操作得到的。
进而，手机的WMS遍历窗口界面71的Activity，窗口界面72的Activity，以及窗口界面73的Activity，以确定每个Activity中是否包含flag(可以理解为判断flag是否置位)。示例性的，WMS确定窗口界面71的Activity和窗口界面72的Activity均不包含flag，而窗口界面73的Activity中包含第一flag。之后，手机向笔记本电脑发送task 0、task 1、task 2、窗口界面71和窗口界面72的视频流、以及安全保护指令。其中，窗口界面71的视频流与task 0对应，窗口界面72的视频流与task 1对应，安全保护指令与task 2对应。进而，笔记本电脑分割窗口界面71和窗口界面72的视频流，以及显示投屏界面711、投屏界面712。并且，笔记本电脑响应安全保护指令将窗口界面73的投屏界面显示为安全界面，以得到投屏界面713。
一些实施例中，手机向笔记本电脑投屏第一组窗口界面之后，手机的显示屏可以始终 显示手机桌面。手机响应来自于笔记本电脑的操作指令显示的窗口界面，可以在虚拟display显示。
场景二：用户在手机端操作
本申请实施例中，手机接收用户输入的第二操作指令之后，通常在手机的桌面显示指令触发的第二APP界面。这样，手机的桌面更新，进而手机的display也随之更新。那么，手机可以基于更新后的display向笔记本电脑投屏，使得笔记本电脑的投屏界面随之更新。图9中的(a)至(c)示意了场景二中的一种示例性显示方法。图10中的(a)至(b)示意了随图9示意的实施过程，手机端display的示意性变化过程。
如图9中的(a)所示，GUI90是手机将图10中的(a)示意的display101投屏到笔记本电脑之后，笔记本电脑的显示界面。GUI90包括投屏界面901和投屏界面902，投屏界面901例如是手机桌面的投屏界面。投屏界面902例如是备忘录的窗口界面的投屏界面。其中，投屏界面701对应标识task 0，投屏界面701对应标识task 1。
如图9中的(b)所示，GUI91是手机的桌面，GUI91包含邮箱等界面元素。在将display101投屏到笔记本电脑之后，手机例如接收到用户点击输入的第二操作指令，该第二操作指令例如用于启动第二APP。第二APP例如是邮箱APP。进而，由于用户需要在手机端对邮箱进行操作，所以，本实施例中，手机在显示屏显示邮箱的登录界面。邮箱的登录界面如图12所示，此处不详述。相应的，手机桌面对应的窗口界面更新为邮箱的登录界面，display101更新为图10中的(a)示意的display102。之后，手机将display102投屏到笔记本电脑，使得笔记本电脑的GUI91更新为图9中的(c)示意的GUI92。
图9中的(c)示意的GUI92是手机将图10中的(b)示意的display102投屏到笔记本电脑之后，笔记本电脑的显示界面。GUI92包括投屏界面921和投屏界面922，投屏界面921是邮箱的窗口界面的投屏界面，例如是如图6所示的安全界面。投屏界面922例如是备忘录的窗口界面的投屏界面。其中，投屏界面921对应标识task 0，投屏界面922对应标识task 1。
如图10中的(a)所示，display101中包括窗口界面1011和窗口界面1012。DMS为窗口界面1011设置标识task 0，以及为窗口界面1012设置标识task 1。窗口界面1011投屏得到GUI90中的投屏界面901。窗口界面1012投屏得到GUI90中的投屏界面90。display101与图8中的(a)所示的display80类似，此处不详述。
如图10中的(b)所示，display102中包括窗口界面1021、窗口界面1022和窗口界面1023。其中，窗口界面1021与窗口桌面1011相同，是手机的桌面，窗口界面1022与窗口界面1012相同，是备忘录的界面，窗口界面1023是邮箱的登录界面，对应标识task 2。即，手机响应第二操作指令显示邮箱的登录界面之后，AMS启动邮箱APP，以及进入邮箱登录界面，并为邮箱APP配置标号task 2。DMS在display101基础上执行扩展，得到display102，以能够容纳窗口界面1023。进而，本实施例中，手机可以值将窗口界面1022和窗口界面1023投屏到笔记本电脑。具体实现时，手机通过WMS可以确定窗口界面1023是具备安全需求的界面，而窗口界面1022无安全需求。之后，手机将task 1、task 2、安全保护指令和窗口界面1012的视频流发送到笔记本电脑。其中，task2与安全保护指令对应，task 1与窗口界面1012的视频流对应。进而，笔记本电脑显示GUI92。
基于与图9和图10示意的实施例同样的原理，在图5C-2对应的实施例中，手机接收 到用户触发窗口界面561显示的指令，或者用户触发窗口界面561显示的指令，手机的桌面界面更新为具备安全需求的窗口界面。进而，手机基于更新后的窗口界面再次投屏，使得笔记本电脑端task 0对应的投屏界面是安全界面。
另一些实施例中，若手机响应第二操作指令显示的界面无安全需求，那么，手机的显示屏显示的是无安全要求的窗口界面，进而，手机可以将相应窗口界面的图像投屏到笔记本电脑。相应的，笔记本电脑可以显示相应窗口界面的投屏界面和备忘录窗口界面的投屏界面。
可见，采用本实现方式，手机将待投屏的窗口界面和task ID关联，在窗口界面更新之后，手机可以通过task ID指示笔记本电脑显示每个窗口界面的投屏界面，从而使得笔记本电脑能够以窗口界面为单位显示投屏界面，既能够安全显示有安全要求的界面，也能够确保用户对无安全要求的界面正常操作。
对安全界面操作之后的显示阶段：
对应上述场景一，当笔记本电脑将第一APP的投屏界面显示为安全界面之后，用户可以通过该笔记本电脑触发相应窗口界面在手机的显示屏显示，以在手机端对第一APP继续操作。其中，第一APP的窗口界面在手机的显示屏显示，以及用户继续操作，均会触发手机端display的更新，进而，触发笔记本电脑端所显示的投屏界面的变化。
以下结合图11和图12，对第一APP的窗口界面在手机的显示屏显示的场景中，笔记本电脑的显示方法以及手机端display的变化过程进行描述。
接前述场景一，图11中的(a)中笔记本电脑的GUI例如是GUI71，其中，投屏界面713包括图标1101，图标1101与图6中的图标62相同，此处不赘述。在接收到用户点击图标1101的操作后，笔记本电脑生成第三操作指令，该第三操作指令用于触发手机在显示屏显示图12示意的邮箱的登录界面，以便于用户在手机端对邮箱执行登录操作。进而，手机端的display81中的窗口界面73在手机的显示屏显示，使得手机呈现图12的界面。进而，手机可以基于display81，将窗口界面72和窗口界面73再次投屏到笔记本电脑，使得笔记本电脑的GUI71更新为图11中的(b)示意的GUI111。
其中，笔记本电脑接收用户的点击操作之后，可以获取投屏界面713对应的标识task 2。之后，笔记本电脑生成第三操作指令，该第三操作指令中包含标识task 2。进而，手机可以根据标识task 2确定邮箱的登录界面。
图11中的(b)示意的GUI111是手机将图8中的(b)示意的display81投屏到笔记本电脑之后，笔记本电脑的显示界面。GUI111包括投屏界面1111和投屏界面1112。投屏界面1111对应标识task 0，投屏界面1112对应标识task 1。其中，投屏界面1111是邮箱登录界面的投屏界面，投屏界面1111是如图6所示的安全界面。投屏界面1112是备忘录的窗口界面的投屏界面，投屏界面1112与GUI71中的投屏界面712相同，此处不详述。
结合图8中的(b)示意的display81，本实施例中，手机可以基于窗口界面72左上角的起始坐标获取窗口界面72的视频流并渲染，然后，将task 1、task 2、渲染得到的视频流以及安全保护指令发送到笔记本电脑，其中，task 1对应视频流，task 2对应安全保护指令。进而，笔记本电脑显示task1对应的投屏界面1112，以及task2对应的投屏界面1111。需要指出的是，本实施例中，手机发送的投屏信息中不包含display81内task0以及与task0对应的信息(即手机桌面的界面)，所以，GUI111中不包含task 0对应的投 屏界面。从用户视觉效果上看，GUI71更新为GUI111过程中，笔记本电脑删除了投屏界面713，并将投屏界面711更新为安全界面。
图12示意的GUI120是手机端的邮箱登录界面。GUI120包括输入“邮箱帐号”的控件1201、输入“密码”的控件1202以及“登录”按钮1203等界面元素。其中，控件1202中包括提醒信息“输入密码”，提示信息“输入密码”的字体灰度值较低，以提醒用户在该控件中输入邮箱的登录密码。在接收到用户输入的密码之后，提示信息“输入密码”隐藏。一些实施例中，控件1201中包括提醒信息“输入邮箱帐号”，提示信息“输入邮箱帐号”的字体灰度值较低，以提醒用户在该控件中输入邮箱的登录帐号。在接收到用户输入的帐号之后，提示信息“输入邮箱帐号”隐藏。另一些实施例中，控件1201中包括邮箱的登录账号，控件1202中包括提醒信息“输入密码”。在手机通过显示屏显示GUI120的场景中，手机的display由display81更新为display142。
进一步的，以下结合图13至图14B，对手机接收用户对第一APP执行的操作之后，笔记本电脑的显示方法以及手机端display的变化过程进行描述。
需要指出的是，图11中的(b)对应的实施场景与图9中的(c)对应的实施场景相同。基于此，以下显示方法的实施例对于上述两种实施场景均适用，本申请实施例不再重复描述。
结合图12，手机可以接收用户点击按钮1203输入的登录指令，该登录指令中包含用户输入的邮箱帐号和密码。在确定相应邮箱帐号和密码正确无误之后，AMS调用邮箱主界面的Activity，相应的，手机显示邮箱的主界面。邮箱的主界面如图13中task 2标识的窗口界面所示。
图13示意的display142包括窗口界面1421、窗口界面1422和窗口界面1423，窗口界面1421对应标识task 0，是手机桌面。窗口界面1422对应task 1是备忘录的窗口界面。窗口界面1423对应task 2，是邮箱主界面的窗口界面。本实施例中，在确定邮箱帐号和密码均正确之后，DMS可以控制display81中task 0对应的登录界面关闭或隐藏，并通过新的窗口界面显示邮箱主界面。这样，使得task 0标识的窗口界面更新为手机桌面，且，增加了新的窗口界面。进一步的，AMS为新的窗口界面配置标识task 2，以得到图13示意的display142。
一些实施例中，手机可以将display142中窗口界面1422和窗口界面1423投屏到笔记本电脑端，得到图14A示意的GUI151。另一些实施例中，手机可以将display142中的所有窗口界面均投屏到笔记本电脑端，得到图14B示意的GUI152。
如图14A所示，GUI151包括投屏界面1511和投屏界面1512。其中，投屏界面1511对应task 1，是display142中窗口界面1422的投屏界面。投屏界面1512对应task 2，是display142中窗口界面1423的投屏界面。
如图14B所示，GUI152包括投屏界面1521、投屏界面1522和投屏界面1523。其中，投屏界面1521对应task 0，是display142中窗口界面1421的投屏界面。投屏界面1522对应task 1，是display142中窗口界面1422的投屏界面。投屏界面1523对应task 2，是display142中窗口界面1423的投屏界面。
需要指出的是，上述手机与笔记本电脑之间各项信息和指令的交互，均可以基于WiFi Direct技术。
可以理解的是，图5A至图14B仅是示意性描述，对本申请实施例不构成限制。在另一些实施例中，上述显示方法的实施例，同样适用于手机其他APP的显示，此处不再一一描述。另外，上述各场景下的GUI可以根据手机型号，所搭载的系统的版本等的不同而不同。此处不再详述。
另外，上述实施例仅是以手机和笔记本电脑为例进行的说明，对本申请实施例不构成限制。在另一些实施例中，本申请实施例涉及的第一设备还可以实现为折叠屏设备、平板电脑等，本申请实施例涉及的第二设备还可以实现智慧屏等。此处不限制。
以下以第一设备实现为手机，第二设备实现为PC为例，对本申请实施例涉及的显示方法的整体流程进行描述。
参见图15，图15示意了本申请的第三种示例性显示方法。在一些实施例中，手机侧进行多屏协同。手机侧首先判断是否当前位多屏协同，若不是则采用默认应用锁策略(即手机侧不会将视频流发送至PC侧)，若是手机侧判断是否处于安全输入界面，不是则使用默认窗口显示，是则向PC发送处于安全输入界面的应用对应的task ID和遮盖画面(该遮盖画面也可选地预先存储在PC上)。手机待用户输入完密码后(window state对应的flag复位)，通知PC。PC取消对安全输入界面对应的应用窗口的遮盖。
可以理解的是，相对于传统的解决方案在遇到安全标志位flag时不会将display上的内容投至对端设备。本申请实施例的方案不管有没有安全标志位flag时都会将display上的内容投至对端设备，与此同时传递安全标志位flag，告诉PC对存在安全标志位flag进行安全图层遮盖，实现多屏协同多窗口的安全保障。
综上，本申请实施例的显示方法，第一设备在投屏之前确定各个窗口界面是否具备安全需求，进而，第一设备根据检测结果，将每个窗口界面的taskID以及该窗口界面的投屏信息发送到第二设备。第二设备基于taskID显示安全界面和包含窗口界面内容的投屏界面，其中，安全界面是有安全需求的窗口界面的投屏界面。这样，第二设备既能够安全显示有安全要求的界面，也能够确保用户对无安全要求的界面正常操作。
尽管已描述了本申请的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例作出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本申请范围的所有变更和修改。
显然，本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的精神和范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在内。
