具体实施方式
本申请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”旨在也包括复数表达形式，除非其上下文中明确地有相反指示。还应当理解，本申请中使用的术语“和/或”是指并包含一个或多个所列出项目的任何或所有可能组合。
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。
在一些实施例中，电子设备可以同时启动多个应用程序，并且可以打开多个窗口，在多个窗口中的每个窗口中显示一个应用程序的用户界面。在电子设备打开多个窗口的情况下，电子设备可以设置其中一个窗口为焦点窗口，并设置该焦点窗口对应的应用程序为焦点应用程序(例如，焦点窗口中显示了应用程序F1的用户界面，则焦点窗口对应的应用程序为应用程序F1。)；当电子设备检测到针对电子设备的操作时(例如电子设备与键盘和鼠标通信连接，用户可以按压键盘上的翻页键实现翻页功能，或者可以转动鼠标的滑轮实现翻页功能)；电子设备根据操作针对焦点应用程序的数据进行处理，进而满足用户的使用需求。具有多任务处理能力的操作***(例如微软视窗(Microsoft TM Windows)操作***，安卓(Android TM操作***等)，在开启多个窗口/多个应用程序的情况下，均具有设置焦点窗口/焦点应用程序的功能特性。
下面是焦点应用程序和焦点窗口的解释：焦点应用程序在不同的操作***中可以有不同的定义。例如在安卓操作***中可以是焦点应用程序(Focused application)。举例来说，焦点应用程序可以有如下作用：当电子设备运行多个应用程序的情况下，电子设备可以设置其中一个应用程序为焦点应用程序，进而在电子设备检测到满足条件的操作(可以是用户触控显示屏上的可触控区域，用户通过键盘、鼠标输入的操作指令等)时，根据满足条件的操作针对焦点应用程序的数据进行处理。可见，在电子设备运行多个应用程序的情况下，设置焦点应用程序的方法可以使电子设备准确的确定出需要执行数据处理的应用程序，进而避免数据处理对象的错误。
焦点窗口在不同***中可以有不同的定义，例如在微软视窗(Microsoft Windows)***中焦点窗口为活动窗口(Active window)，活动窗口拥有焦点。焦点窗口可以有如下作用：电子设备可以根据满足预设条件的操作和焦点窗口显示的内容确定出待处理的数据，进而针对待处理的数据执行数据处理操作。本申请实施例中，电子设备设置的焦点窗口和非焦点窗口呈现的显示效果不同，使得用户可以辨别出焦点窗口和非焦点窗口；例如电子设备可以改变焦点窗口的透明度，以区别于非焦点窗口；或者，电子设备可以设置焦点窗口的标题栏为高亮状态，或者，电子设备改变焦点窗口的标题栏中字体的大小，粗细，颜色值等；使得用户在浏览电子设备上的多个窗口时可以从多个窗口中确定出焦点窗口。
在一些实施例，电子设备100与电子设备200通信连接；电子设备200的显示界面大于电子设备100的显示界面。显示界面指的是显示屏上全部可显示区域。电子设备100在同一时刻可以运行至少一个应用程序；电子设备100在与电子设备200通信连接的情况下向电子设备200发送显示数据；电子设备200根据显示数据在电子设备200的显示屏上显示至少一个应用程序的窗口，使得用户可以在电子设备200上查看和操作至少一个应用程序，实现电子设备之间的联动。用户可以同时使用电子设备100和电子设备200查看和操作至少一个应用程序，因此提升了用户查看和操作至少一个应用程序时的效率，提升了用户体验。
用户在电子设备200上针对至少一个应用程序中的目标应用程序执行操作时，电子设备200根据用户的操作生成响应数据，之后向电子设备100发送响应数据，电子设备100根据响应数据针对目标应用程序执行对应的操作。
当电子设备100同时运行多个应用程序时，电子设备200根据电子设备100的显示数据显示多个应用程序对应的多个窗口；电子设备100在本端显示界面上显示的窗口为窗口W1，窗口W1显示应用程序F1的用户界面，应用程序F1为电子设备100设置的焦点应用程序。电子设备200设置用户最近一次操作过的窗口W2为焦点窗口，窗口W2显示应用程序F2的用户界面。若应用程序F1和应用程序F2为同一应用程序，用户可以在电子设备100和电子 设备200之间实现无缝的操作切换，电子设备100根据用户在电子设备100和电子设备200上的操作针对焦点应用程序进行处理，进而满足用户的需求。但在应用程序F1和应用程序F2不是同一应用程序的情况下，则可能存在用户在电子设备200上执行了操作，且该操作为针对窗口W2中的应用程序F2的操作；电子设备200根据该操作生成响应数据，之后向电子设备100发送响应数据；由于电子设备100设置的焦点应用程序为应用程序F1，因此，可能会出现电子设备100根据响应数据针对应用程序F1执行了数据处理的操作；导致处理目标错误的情况。
在一些实施例中，多个应用程序可以始终运行在电子设备100上，电子设备200仅用于显示多个应用程序的窗口。
举例来说，请参阅图1A，图1A包括电子设备100和电子设备200。如图所示，电子设备100与电子设备200通信连接。电子设备100的显示屏上包括窗口101。电子设备100向电子设备200实时发送显示数据；电子设备200根据显示数据显示了3个窗口；3个窗口分别是窗口201，窗口202和窗口203；窗口201显示计算器应用程序的用户界面；窗口202显示图库应用程序的用户界面；窗口203为主窗口，与窗口101的显示内容相同，即窗口203显示的用户界面和窗口101显示的用户界面具有相同的用户界面元素；例如图1A中窗口203和窗口101中均包括：日历，时钟，华为视频等应用程序的图标。需要说明的是，主窗口指的是电子设备200根据电子设备100发送的显示数据显示的多个窗口中的一个窗口；主窗口203的部分/全部显示内容与电子设备100的窗口101的部分/全部显示内容相同。需要说明的是，电子设备200显示的多个窗口的标题栏中可以包括应用程序的名称。
图1A中窗口202的标题栏2021为高亮状态，即电子设备200设置的焦点窗口为窗口202；表明用户在电子设备200上最近一次的操作为针对图库对应的窗口202的操作。在如图1A所示的情况下，请参阅图1B，电子设备100检测到用户针对窗口101中的信息应用程序的图标1011的触控操作(需要说明的是，用户可以通过语音，手势等交互方式实现与触控操作同样的效果)，电子设备100响应于针对信息应用程序的图标1011触控操作，打开信息应用程序，并更新窗口101的用户界面为信息应用程序的用户界面；同时由于电子设备200可以实时接收电子设备100发送的显示数据，电子设备200根据显示数据更新窗口203的用户界面为信息应用程序的用户界面。具体的，请参阅图1C，图1C为更新窗口101和窗口203的用户界面为信息应用程序的用户界面后的示意图。需要说明的是，图1B中在电子设备100检测到针对窗口101中的信息应用程序的图标1011的触控操作之前，信息应用程序已经处于后台运行状态，且后台记录信息应用程序的用户界面为与联系人“Lisa”的会话界面(具体可以是：在图1A所示的情况之前，电子设备100已经启动了信息应用程序，且从与联系人“Lisa”的会话界面直接返回了图1A中窗口101所示的主窗口的用户界面。)，因此，在电子设备100检测到针对信息应用程序的图标1011触控操作之后，在窗口101中显示了与联系人“Lisa”的会话界面。
图1C所示的情况下，由于用户最近一次操作是在电子设备100上执行的针对信息应用程序的操作，因此电子设备100设置焦点应用程序为信息应用程序。此时，电子设备200的焦点窗口仍为窗口202，即为图库应用程序对应的窗口。
如图1D所示，电子设备200还可以与键盘204和鼠标205通信连接，用户可以通过键盘204和鼠标205实现对电子设备200的操控；窗口201，窗口202和窗口203是电子设备200根据电子设备100的显示数据生成的窗口，在焦点窗口为窗口201，窗口202和窗口203中的一个窗口的情况下，电子设备200可以定义键盘204中的ESC键2041的功能为“返回 上一级”；即在电子设备200上的ESC键2041被触发的情况下，电子设备200显示用户界面a1的上一级用户界面a2；其中用户界面a1为ESC键2041被触发前焦点窗口显示的用户界面。
在用户执行完成图1B所示的触控操作之后，得到图1C所示的情况；若此时用户使用的电子设备由电子设备100切换回电子设备200；由于当前窗口202的标题栏2021为高亮状态，即当前窗口202为电子设备200的焦点窗口。从键盘204上输入的针对电子设备200上单个窗口的操作(如输入信息，删除信息，返回窗口的用户界面的上一级)，用户可视为是针对焦点窗口的操作。当前图库应用程序的用户界面如图1C中窗口202所示，若用户想要将图库应用程序的用户界面返回上一级，则如图1E所示，用户可能直接点击键盘204中的ESC键2041；当用户点击ESC键2041后，请参阅图1F，电子设备将窗口101和窗口203显示的信息应用程序的用户界面返回了上一级，即窗口101和窗口203显示了信息应用程序的信息列表的用户界面；而并未将图库应用程序的用户界面返回上一级。
可见，上述过程中，在电子设备100的焦点应用程序和电子设备200的焦点窗口不不属于同一应用程序的情况下，电子设备100可能针对错误的应用程序执行数据处理操作，影响用户体验。
下面实施例介绍本申请实施例提供的一种焦点同步方法。该方法应用于通信***，通信***包括电子设备100(本申请实施例中也可以被称为第一电子设备)和电子设备200(本申请实施例中也可以被称为第二电子设备)；电子设备100和电子设备200通信连接。电子设备100与电子设备200通信连接的情况下，电子设备100向电子设备200发送显示数据，电子设备200根据显示数据显示多个窗口。多个窗口中的每个窗口显示一个应用程序的用户界面；应用程序是安装并运行于电子设备100上的；多个窗口中窗口203(本申请实施例中也可以被称为第一窗口)显示第一应用程序的第一用户界面，第一应用程序的第二用户界面显示于电子设备100上，第一用户界面和第二用户界面具有相同的用户界面元素。如图2所示，该方法可以包括：
S101，电子设备100检测到焦点切换事件I1(本申请实施例中也可以被称为第一焦点切换事件)，响应于焦点切换事件I1，设置焦点应用程序为应用程序F2(本申请实施例中也可以被称为第三应用程序)。
其中，电子设备100在检测到焦点切换事件I1之前，电子设备的焦点应用程序为应用程序F1(本申请实施例中也可以被称为第二应用程序)。
其中，焦点切换事件I1为启动/切换到应用程序F2的操作；电子设备100可以设置最近一次启动/切换的应用程序为焦点应用程序，本示例中，由于最近一次的焦点切换事件I1用于启动/切换到应用程序F2，因此电子设备100将焦点应用程序由应用程序F1切换至应用程序F2。其中，焦点切换事件I1的表现形式可以是触控操作，语音指令，外设设备输入(例如通过键盘和鼠标执行的操作)。
S102，电子设备100根据应用程序F2的身份标识生成焦点切换数据。
具体的，身份标识可以是安卓操作***中的任务标识(Task ID)。
可选的，在执行步骤S102之前，还可以包括：
S1021：判断应用程序F2的数据是否满足合法性，在应用程序的数据的满足合法性的情况下执行步骤S102。
其中，执行合法性的判断条件可以是预设置的，具体可以根据本申请实施例应用的具体 场景设置合法性的判断条件；例如，电子设备100可以预设置数据类型和数据格式；则在应用程序F2的数据格式和数据类型为预设置的数据类型和数据格式的情况下，确定应用程序F2的数据满足合法性；否则，确定应用程序F2的数据不满足合法性。
其中，在应用程序的数据和不满足合法性的情况下不执行后续步骤。
其中，电子设备100运行的***可以是安卓(Android TM)操作***。安卓操作***中包括应用程序框架层和应用程序层。电子设备100可以调用应用程序框架层和应用程序层生成焦点切换数据。
电子设备100中的应用程序框架层可以执行焦点应用程序的切换操作。应用程序框架层可以监听焦点应用程序的切换操作，并在监听到焦点应用程序的切换操作后执行步骤s11至s14的操作。如图3所示，应用程序框架层包括：任务管理模块，显示内容模块，第一通信模块。应用程序层包括：第二通信模块和数据处理模块。第一电子设备中存储有参考状态标识和参考身份标识；其中，参考身份标识可以是根据应用程序的身份标识设置的；如图3所示，步骤S101，步骤S1021和步骤S102可以具体包括步骤s11～s13。
s11：响应于焦点切换事件I1，任务管理模块设置焦点应用程序为应用程序F2。
s12：任务管理模块调用显示内容模块，显示内容模块获取焦点应用程序的身份标识。
s131：参考状态标识表示第一状态标识，且焦点应用程序的身份标识与参考身份标识相同时，显示内容模块更新参考状态标识为第二状态标识；参考身份标识为最近一次第二电子设备向第一电子设备发送的焦点切换数据中包括的身份标识；即：第一电子设备最近一次根据第二电子设备发送的焦点切换数据设置的焦点应用程序的身份标识与参考身份标识相同。
其中，显示内容模块可以读写状态信息。当参考状态标识表示第一状态标识时，表示当前焦点应用程序为根据电子设备200传输的数据设置的；当参考状态标识表示第二状态标识时，表示当前焦点应用程序为电子设备100根据本端检测到的、用于启动/切换应用程序的操作设置的。
举例来说，如图8A所示，电子设备100检测到用户通过鼠标205控制光标208对于窗口203的点击操作，之后，如图8B所示，电子设备200设置窗口203为焦点窗口，此时，窗口203和窗口101均显示信息应用程序的用户界面；电子设备100设置的焦点应用程序为信息应用程序；由于电子设备100是根据电子设备200发送的焦点切换数据(即是根据电子设备200检测到光标208对于窗口203的点击操作)将信息应用程序设置为焦点应用程序的，因此，电子设备100设置参考状态标识为第一状态标识；同时，电子设备更新参考身份标识为信息应用程序的身份标识。
之后，请参阅图8C，电子设备100检测到针对信息应用程序的用户界面的触控操作(相当于步骤S101中的焦点切换事件I1)；由于此时参考状态标识为第一状态标识且参考身份标识已经是信息应用程序的身份标识，则电子设备100更新参考状态标识为第二状态标识。可见，焦点切换事件I1为针对信息应用程序的操作，且信息应用程序对应的窗口203已经是焦点窗口；此时电子设备100不执行s14以及后续步骤，即电子设备100不向电子设备200发送焦点切换数据，避免电子设备100和电子设备200之间对焦点进行重复设置，避免了资源的浪费。
s132：参考状态标识表示第一状态标识，且焦点应用程序的身份标识与参考身份标识不同时，显示内容模块更新参考状态标识为第二状态标识，并执行步骤s14。
举例来说，请参阅图1C，电子设备200设置的焦点窗口为窗口202，窗口202显示的是 图库应用程序的用户界面；因此，电子设备100设置的焦点应用程序为图库应用程序。同时，图1C中窗口101和窗口203显示的是信息应用程序的用户界面。此时，参考状态标识为第一状态标识，参考身份标识为图库应用程序的身份标识。
请参阅图4A，电子设备100检测到针对信息应用程序的用户界面的触控操作(相当于步骤S101中的焦点切换事件I1)；由于此时参考状态标识为第一状态标识，且参考身份标识为图库应用程序的身份标识，与信息应用程序的身份标识不同；因此，表明最近一次焦点应用程序为根据电子设备200发送的焦点切换数据设置的，且图库应用程序与信息应用程序不同，因此，执行步骤s14以及后续步骤，使得电子设备200将焦点窗口更新为信息应用程序对应的窗口203。
s133：参考状态标识表示第二状态标识时；执行步骤s14。
由于参考状态标识为第二状态标识时，表示电子设备100的焦点应用程序为根据本端检测到的、用于启动/切换应用程序的操作设置的，且电子设备200上的焦点窗口也是根据电子设备100发送的焦点切换数据设置的；因此，当电子设备100的焦点应用程序切换时，执行s14以及后续步骤，使得电子设备200更新焦点窗口为当前电子设备100上的焦点应用程序对应的窗口。
可见步骤s31～s133在有效的同步焦点窗口和焦点应用程序的同时，避免了电子设备100和电子设备200在焦点窗口和焦点应用程序已经同步的情况下进行循环设置，避免了资源的浪费。
s14：显示内容模块调用第一通信模块，第一通信模块向第二通信模块发送信息数据d1，信息数据d1中包括焦点应用程序的身份标识。可选的，信息数据d1中还可以包括参考状态标识。
s15：第二通信模块向数据处理模块发送信息数据d1，数据处理模块对信息数据d1进行处理，得到信息数据d2。
其中，数据处理模块对信息数据d1进行处理得到信息数据d2的过程可以包括：针对信息数据d1的数据格式进行转换，得到信息数据d2；其中，信息数据d1的数据格式为电子设备100中可以读写的数据格式，信息数据d2的数据格式为电子设备200可以读写的数据格式。
S16：数据处理模块对信息数据d2进行封装，得到焦点切换数据。
S103，电子设备100向电子设备200发送焦点切换数据。
S104，电子设备200根据焦点切换数据设置应用程序F2对应的窗口W2为焦点窗口。
本申请实施例中，窗口W2也可以被称为第三窗口。
具体的，电子设备200可以解析焦点切换数据，得到应用程序F2的身份标识，并根据应用程序F2的身份标识确定出应用程序F2对应的窗口W2；之后，设置窗口W2为焦点窗口。其中，电子设备200在设置窗口W2为焦点窗口之后，还可以包括：电子设备200对设置窗口W2为焦点窗口的场景进行判断；本示例中，电子设备200判断出在电子设备200是根据电子设备100发送的焦点切换数据设置窗口W2为焦点窗口的情况下，电子设备200不执行后续操作。电子设备200对设置窗口W2为焦点窗口的场景进行判断的另一种情况：即在电子设备200是根据本端检测到的操作设置焦点窗口W2的情况下时(此时设置窗口W2为焦点窗口相当于步骤S201)，执行图7所示实施例中的步骤S202～S204。
在一些实施例中，电子设备200在将窗口W2设置为焦点窗口，还可以包括：电子设备200针对焦点窗口进行标记，使得用户可以通过窗口W2的标记确定出窗口W2为焦点窗口。 具体的，针对焦点窗口进行标记可以包括：(1)设置焦点窗口的标题栏为高亮状态。(2)调整焦点窗口的透明度。
举例来说，请参阅图1C，图1C为执行步骤S101之前电子设备100和电子设备200的状态，窗口202的标题栏2021为高亮状态，表示此时电子设备200设置的焦点窗口为窗口202；电子设备200中窗口203为主窗口。请参阅图4A，图4A为电子设备100检测到触控操作，该触控操作用于从与联系人“Lisa”的会话界面返回到信息列表(即返回窗口101中的用户界面的上一级)的界面，本示例中的触控操作是步骤S101中焦点切换事件I1的一种具体表现形式；之后，电子设备100和电子设备200执行S101至S104的步骤，电子设备100和电子设备200执行完成S101至S104的步骤之后，具体状态如图4B所示。图4B中窗口203的标题栏2031为高亮状态，表示此时焦点窗口为窗口203；且图4B中窗口203和窗口101中显示的用户界面为图1C中窗口203和窗口101显示的用户界面的上一级，即由与联系人“Lisa”的会话界面返回到了信息列表的界面。
在一些实施例中，电子设备200将窗口W2设置为焦点窗口，还可以包括：电子设备200将焦点窗口置于显示界面中的最顶层，使得显示界面中的其他窗口无法遮盖焦点窗口。
举例来说，请参阅图5A，图5A为执行步骤S101之前电子设备100和电子设备200的状态，可见窗口206的标题栏2061为高亮状态，表示此时电子设备200设置的焦点窗口为窗口206；图5A中还包括显示界面207，显示界面207表示电子设备200的全部可显示区域；由图5A可以看出，窗口206位于显示界面207的顶层，窗口206遮盖了窗口201的部分和窗口203的部分；窗口203为电子设备200的主窗口。请参阅图5B，图5B为电子设备100检测到触控操作，该触控操作用于从与联系人“Lisa”的会话界面返回到信息列表(即返回窗口101中的用户界面的上一级)的界面，本示例中的触控操作是步骤S101中焦点切换事件I1的一种具体表现形式；之后，电子设备100和电子设备200执行S101至S104的步骤，电子设备100和电子设备200执行完成S101至S104的步骤之后，具体状态如图5C所示。可见，图5C中，电子设备200将窗口203的窗口至于显示界面207的顶层，使得电子设备200可以完整的显示窗口203；同时，电子设备200设置窗口203的标题栏2031为高亮状态，表示窗口203为电子设备200的焦点窗口。
需要说明的是，窗口206可以是根据电子设备100发送的显示数据生成的窗口，也可以是电子设备200显示的安装在电子设备200上的应用程序对应的窗口，此处不作限定。
在一些实施例中，如图6A所示，电子设备200还可以与键盘204和鼠标205通信连接。键盘204中包括ESC键2041，ESC键2041的功能为“返回上一级”。在完成步骤S104之后，电子设备100和电子设备200的状态可以如图5C所示；在步骤S104之后，还可以包括：如图6A所示，电子设备200检测到针对ESC键2041的按压操作；之后，电子设备200向电子设备100发送根据该按压操作生成的数据，电子设备100根据接收到的数据针对信息应用程序的数据进行处理，得到显示数据；并向电子设备200发送该显示数据；电子设备100和电子设备200根据该显示数据显示如图6B所示的用户界面，在窗口101和窗口203的用户界面中显示“再按一次退出”的标识；以提示用户再按一次ESC键可以退出信息应用程序；“再按一次退出”的标识具体为窗口101中的1012和窗口203中的2032。本示例中，在步骤S104之后，窗口203和窗口101显示的是信息应用程序中的信息列表；由于信息列表已经是信息应用程序最上一级的用户界面，无法进一步执行返回上一级，因此，本示例中窗口101和窗口203显示“再按一次退出”的标识。电子设备100中的焦点应用程序显示的用户界面为最上一级的用户界面的情况时，连续按两次ESC键2041可以退出焦点应用程序。
在一些实施例中，步骤S101中焦点切换事件I1用于打开应用程序F2，若应用程序F2的用户界面在用户执行焦点切换事件I1之前已经显示在电子设备200中的子窗口b1中，则在步骤S104中，电子设备200在主窗口显示应用程序F2的用户界面，并设置主窗口为焦点窗口；同时电子设备200可以关闭子窗口b1；子窗口表示多个窗口中除主窗口之外的窗口；子窗口b1为电子设备200打开的子窗口中的一个子窗口。举例来说，在步骤S101之前，电子设备100和电子设备200的状态如图1A所示，可见，窗口203为电子设备200的主窗口；电子设备200中的窗口202显示的用户界面为图库应用程序的用户界面；请参阅图6C，步骤S101中的第一操为针对窗口101中的图库应用程序的图标1013的触控操作，即焦点切换事件I1用于打开图库应用程序，由于图库应用程序的用户界面已经在窗口202中进行显示，因此，如图6D所示，电子设备100在窗口101中显示图库应用程序的用户界面，电子设备200在窗口203中显示图库应用程序的用户界面并设置窗口203为焦点窗口；同时，电子设备200关闭窗口202。
下面实施例介绍本申请实施例提供的另一种焦点同步方法。该方法应用于通信***，通信***包括电子设备100和电子设备200；电子设备100和电子设备200通信连接。电子设备100与电子设备200通信连接的情况下，电子设备100向电子设备200发送显示数据，电子设备200根据显示数据显示多个窗口。如图7所示，该方法可以包括：
S201，电子设备200检测到焦点切换事件I2(本申请实施例中也可以被称为第一焦点切换事件)，响应于焦点切换事件I2，设置焦点窗口为窗口W4(本申请实施例中也可以被称为第三窗口)。
其中，电子设备200将窗口W4设置为焦点窗口，可以包括：电子设备200针对焦点窗口进行标记，使得用户可以通过窗口W4的标记确定出窗口W4为焦点窗口。具体的，针对焦点窗口进行标记可以包括：(1)设置焦点窗口的标题栏为高亮状态。(2)调整焦点窗口的透明度。
其中，电子设备200将窗口W4设置为焦点窗口，还可以包括：电子设备200将焦点窗口置于显示界面中的最顶层，使得显示界面中的其他窗口无法遮盖焦点窗口。
其中，电子设备200在检测到焦点切换事件I2之前，电子设备200设置的焦点窗口为窗口W3(本申请实施例中也可以被称为第二窗口)。
其中，焦点切换事件I2是用于开启/切换到应用程序F4(本申请实施例中也可以被称为第三应用程序)对应的窗口W4的操作；电子设备200可以设置最近一次开启/切换到的窗口为焦点窗口，本示例中，由于最近一次的焦点切换事件I2为开启/切换到窗口W4，因此电子设备200将焦点窗口由窗口W3切换至窗口W4。其中，焦点切换事件I2的表现形式可以是触控操作，语音指令，外设设备输入(例如通过键盘和鼠标执行的操作)。
举例来说，在执行步骤S201之前电子设备100和电子设备200的状态可以如图1C所示；之后，如图8A所示，电子设备200检测到通过鼠标205控制光标208对于窗口203的点击操作；之后，如图8B所示，电子设备200设置窗口203为焦点窗口。
S202，电子设备200根据窗口W4的身份标识生成焦点切换数据。
具体的，电子设备200在检测到用于开启/切换到应用程序F4对应的窗口W4的操作之后，电子设备200首先确定窗口W4的身份标识；之后，电子设备200根据窗口W4的身份标识生成焦点切换数据。
