具体实施方式
下面将结合附图对本申请的实施例作进一步地详细描述。
为了解决上述投屏过程中两个电子设备显示风格不一致的问题，本申请提供了一种投屏方案。在本申请实施例的投屏方案中，电子设备会根据被投屏设备的显示风格修改将要投屏的显示内容的显示风格， 然后再进行投屏。电子设备的显示风格可以用显示参数来表示，显示参数包括字体样式、字体大小、字体颜色、图标颜色、图标大小、背景颜色、背景图案、控件属性中的至少一个。本申请中描述的显示界面具有显示参数，可以是指显示界面上的显示内容按照一定的参数进行显示。
图2根据本申请的一些实施例示出了一种屏幕协同系统。
具体地，如图2所示，该屏幕协同系统包括第一电子设备100、第二电子设备200以及服务器300。其中，第一电子设备100能够分别与第二电子设备200和服务器300进行无线通信。当第一电子设备100向第二电子设备200进行投屏时，第一电子设备100可以从第二电子设备200获取第二电子设备200当前的显示界面202的显示参数。然后第一电子设备100生成一个投屏界面104，投屏界面104的显示内容与第一电子设备100屏幕上当前显示的显示界面103的显示内容相同，但是第一电子设备100根据获取到的第二电子设备200的显示参数，调整投屏界面104的显示参数与第二电子设备200发送的相同，以使得投屏界面104的显示风格与第二电子设备200的显示界面202的显示风格协调一致，然后第一电子设备将显示风格调整后的投屏界面104投屏至第二电子设备200，并且在此过程中，可以不改变第一电子设备100的当前显示界面103的原有显示风格。
可以理解，在本申请的一些实施例中，显示参数可以包括第二电子设备200显示界面202中正在使用的字符的字体样式、字体大小、字体颜色、图标颜色、图标大小、背景颜色、背景图案、控件属性等参数，下文将进行详细描述。可以理解，对于一些电子设备，如手机、平板电脑等，字体样式、字体大小、字体颜色、图标颜色、图标大小、背景颜色、背景图案、控件属性等也可以统一地包括在一种主题模式中，例如，老人模式(简易模式)，深色模式等。这里的控件可以包括第一电子设备100的显示界面103中的图标、按钮、菜单、选项卡、文本框、对话框、状态栏、导航栏等。控件属性可以包括上述控件的大小，位置，排列顺序以及是否显示等属性。
在第一电子设备100上不具备第二电子设备200的显示参数所代表的显示功能时，例如，第一电子设备100不具备显示参数中的字体大小、字体样式、背景图案，背景颜色等参数所对应的显示功能的情况下，第一电子设备100还可以服务器300获取上述缺失的显示功能。其中，服务器300可以用于存储和更新显示功能，并应第一电子设备100的请求或者主动将存储或者更新后的显示功能发送给第一电子设备100。
如图2所示，服务器300可以自行收集和更新的显示功能。例如，服务器300可以从各个电子设备(如各第二电子设备200)或从各个字体大小、字体样式、背景图案、背景颜色以及控件属性，或者主题模式的开发者处收集不同显示风格所包括的各种显示功能(例如，开发者在服务器300的应用商店中注册或上架字体大小、字体样式、背景图案，背景颜色以及控件属性，主题模式；再如，服务器300请求各个电子设备上报自身存储的字体大小、字体样式、背景图案，背景颜色以及控件属性，主题模式)。服务器300还可以基于第一电子设备100的请求或者通过定期推送的方式，将最新收集到的字体大小、字体样式、背景图案，背景颜色以及控件属性，主题模式等显示风格参数发送给第一电子设备100。
此外，可以理解，在本申请的实施例中，第一电子设备100在第二电子设备200的局部投屏区域，可以是第二电子设备200的屏幕中与第一电子设备100的显示界面103或者屏幕的尺寸相同的局部投屏区域，例如，将手机上的显示界面投屏到屏幕尺寸大于手机的平板电脑上的局部投屏区域内。也可以是将电子设备的显示界面缩小后投屏到第二电子设备200中，例如，在第二电子设备200接受投屏的区域或者第二电子设备200的屏幕尺寸可以小于第一电子设备100的显示界面103的尺寸的应用场景中。此外，第一电子设备100还可以将屏幕上的显示界面103同时投屏到多个第二电子设备200，并分别适应每个被投屏的第二电子设备200的显示风格。
图3a至图3e分别示出了多种投屏场景。其中，在图3a所示的场景中，第一电子设备100以手机100为例，第二电子设备200以平板电脑200为例，手机100与平板电脑200进行上述多屏协同显示，即手机100将显示界面103显示在平板电脑200上的显示界面202的局部投屏区域中。该局部投屏区域的大小与手机100当前显示界面103的大小相同。在进行投屏时，手机100可以获取平板电脑200的显示界面202的显示参数，并根据获取的平板电脑200的显示参数调整显示界面103的显示参数，从而调整显示界面103的显示风格，例如，在图3a，手机100可以生成一个处于非显示模式(即对于用户不可见)的投屏界面104，该投屏界面104的显示内容与显示界面103相同，而将该投屏界面104内的字体样式从楷体修改为宋体，背景颜色从粉色修改为白色，背景图案从有涟漪图案修改为无涟漪图案，并保持手机100的屏幕中当前的显示界面103不改变，最后将显示风格修改后的投屏界面104投屏至平板电脑200的局部投屏区域内。从图3a可以看出，在平板电脑200的显示界面202上显示的手机100的投屏界面104的显示风格与平板电脑200的显示界面202的显示风格保持了一致。
在图3b所示的场景中，第一电子设备100和第二电子设备200还是分别以手机100和平板电脑200为例，并且手机100与平板电脑200进行多屏协同显示，其中手机当前的显示界面103中显示有即时通信应用(Application，APP)，平板电脑200当前的显示界面202的显示风格为老人模式(简易模式)。手机100从平板电脑200获取到的显示参数表示老人模式后，手机100可以创建一个显示内容与手机100的当前的显示界面103相同的投屏界面104(非显示模式，对用户不可见)，并对应于老人模式，手机100将投屏界面104中字符的字体调大、字体样式从楷体修改为宋体、背景颜色从粉色修改为白色，背景图案从有涟漪图案修改为无涟漪图案、并简化当前显示的即时通信APP的显示内容，例如，将投屏界面104中即时通信APP中的搜索栏1002设置为不显示，同时，将通信栏目1003中“工作群”的内容预览设置为不显示(可以理解，在其他实施例中，也可以是减少工作群中的文字内容)，最后将显示风格修改后的投屏界面104投屏至平板电脑200的局部投屏区域内。从图3b可以看出，在平板电脑200的显示界面202上显示的手机100的投屏界面104的显示风格与平板电脑200的显示界面202的显示风格保持了一致。
图3c与图3b所示的场景类似，不同之处在于平板电脑200的显示风格为深色模式。手机100从平板电脑200获取到显示参数表示深色模式或者获取到的显示参数包括背景颜色、图标颜色、字体颜色等参数时，手机100同样可以创建一个显示内容与手机100的当前的显示界面103相同的投屏界面104(非显示模式，对用户不可见)，并对应于深色模式，手机100将投屏界面104中即时通信APP的文字内容以及通信栏目1003内的图标设置为浅色，如白色，并将背景颜色改为颜色与平板电脑200的显示界面202相同的深色。最后将显示风格修改后的投屏界面104投屏至平板电脑200的局部投屏区域内。从图3c可以看出，在平板电脑200的显示界面202上显示的手机100的投屏界面104的显示风格与平板电脑200的显示界面202的显示风格保持了一致。
在图3d所示的场景中，第一电子设备100以手机为例，第二电子设备200以智能手表为例，智能手表200的屏幕小于手机100的屏幕或者手机100上显示界面103的大小，在手机100将显示界面103投屏到智能手表200的显示界面202的局部投屏区域时，可以将显示界面103通过等比例缩放的方式缩小后发送给智能手表200进行显示。具体地，在进行投屏时，手机100获取智能手表200的显示参数和智能手表200用于投屏的局部投屏区域的尺寸信息，并且手机100根据手表200的显示参数调整显示界面103的显示参数，从而调整显示界面103的显示风格，例如，如图3d所示，智能手表200的显示界面202中的字体为宋体，而手机100的显示界面103中的字体为楷体。手机100根据显示参数中的字体参数，可以将生成的投屏界面104内的字体样式从楷体修改为宋体，然后根据获取到的局部投屏区域的 尺寸信息，将投屏界面104按照等比例缩放后投屏至智能手表200的显示界面202的局部投屏区域内。从图3d可以看出，在智能手表200的显示界面202上显示的手机100的投屏界面104的显示风格与智能手表200的显示界面202的显示风格保持了一致。此外，可以理解，手机100在生成投屏界面104后，也可以直接发送给智能手表200，由智能手表200根据自身用于投屏的局部投屏区域的大小，对其进行缩放后显示在智能手表200的显示界面202上。
在图3e所示的场景中，公开了将第一电子设备100的显示界面同时投屏到多个第二电子设备200的场景。其中，以将手机100的显示界面103同时投屏到智能手表200-1和车机200-2上为例进行说明。如图3e所示，在投屏时，手机100可以从智能手表200-1和车机200-2分别接收各自对应的显示参数，然后根据两者的显示参数创建分别对应智能手表200-1和车机200-2的第一投屏界面105和第二投屏界面106，并将创建的第一投屏界面105和第二投屏界面106分别投屏至智能手表200-1和车机200-2。具体地，如图3e所示，手机100的显示界面103中字符的字体为楷体，背景颜色为粉色；智能手表200-1的显示界面202中字符的字体为华文彩云，且背景颜色为白色；车机200-2的显示界面204中字符的字体为宋体，且背景颜色为白色。故在生成第一投屏界面105时，手机将第一投屏界面105内字体样式从楷体修改为华文彩云，将背景颜色修改为白色，然后将显示风格修改后的第一投屏界面105按照等比例缩放的方式投屏至智能手表200-1的显示界面202的局部投屏区域内。同时，手机100可以将第二投屏界面106内的字体样式从楷体修改为宋体，然后将显示风格修改后的第二投屏界面106投屏至车机200-2的显示界面204的局部投屏区域内。从图3e可以看出，投屏后，两个电子设备分别显示的第一投屏界面105和第二投屏界面106的显示风格分别与智能手表200-1和车机200-2的显示界面202和显示界面204的显示风格保持了一致。
本申请中的第一电子设备100和第二电子设备200可以是能够互相通信的各种计算设备，例如，第一电子设备100和第二电子设备200可以包括但不限于，膝上型计算机、台式计算机、平板计算机、手机、服务器、可穿戴设备、头戴式显示器、移动电子邮件设备、车机设备、便携式游戏机、便携式音乐播放器、阅读器设备、其中嵌入或耦接有一个或多个处理器的电视机、或能够访问网络的其他电子设备。
在下文的描述中，为了简化说明，以第一电子设备100为手机100，第二电子设备200为平板电脑200为例说明本申请的技术方案。为了便于说明，下文以手机100与平板电脑200之间进行多屏协同显示为例进行说明。但是，可以理解，本申请的投屏方案适用于任何电子设备间投屏功能。

在手机100与平板电脑200建立通信连接前或者建立通信连接后，用户可以开启手机100的多屏协同功能，如图1(a)和1(b)所示。在用户开启手机100的多屏协同显示功能后，用户可以选择向与手机100通信连接的平板200发出多屏协同显示请求。
S602：手机100确认是否开启一致性显示模式，如果开启则进入S604；如果没有开启则进入S603。
手机100可以对一致性显示模式的开启/关闭配置相对应的参数。例如，手机100通过显示系统服务101将一致性显示模式配置为参数名consistenceDisplayMode，将一致性显示模式的开启对应的参数值配置为1，将一致性显示模式的关闭对应的参数值配置为0，上述参数以及参数值保存在手机100的存储器中。在手机100向平板电脑发出多屏协同显示请求的同时，手机100查询参数consistenceDisplayMode以及该参数对应的参数值，如果查询到consistenceDisplayMode对应的参数值为1，则手机100确认开启一致性显示模式。如果查询到consistenceDisplayMode对应的参数值为0，手机100确认未开启一致性显示模式。
在本申请的一些实施例中，如图7所示，手机100可以通过在自身的操作系统的系统设置里配置一致性显示模式的开启/关闭的选项1011。用户可以通过点击该开启/关闭的选项1011实现开启/关闭一致性显示模式。
在本申请的另一些实施例中，如图8所示，用户还可以通过设置在手机100上的按键来配置一致性显示模式的开启/关闭。例如，手机100上设置有开启/关闭一致性显示模式的侧键1012，用户可以通 过拨动该侧键1012实现开启/关闭一致性显示模式。
可以理解，在手机100向平板电脑200发出多屏协同显示请求的同时，如果手机100尚未开启一致性显示模式，则手机100可以提示用户是否要开启一致性显示模式，在用户确认开启后，手机100开启一致性显示模式。例如，如图9所示。在手机100与平板电脑200之间进行多屏协同显示时，如果手机100尚未开启一致性显示模式，则在手机100的屏幕中弹出一个提示框1013，提示用户是否开启一致性显示模式，如果用户选择是，则手机100开启一致性显示模式，否则，手机100不开启一致性显示模式。
在手机100与平板电脑200建立多屏协同，第一电子设备100可以从第二电子设备200获取第二电子设备200当前的显示界面202的显示参数，当第一电子设备确定其屏幕上当前显示的显示界面103的显示风格与显示界面202的显示风格不一致时，第一电子设备100可以弹出提示框，提示用户是否要开启一致性显示模式。
S603：手机100将未修改的显示界面103投屏至平板电脑200的显示界面202的局部投屏区域中。
例如，如图1所示，手机100将未修改过显示风格的显示界面103投屏至平板电脑200的显示界面202的局部投屏区域。
S604：手机100向平板电脑200发出获取平板电脑200的显示参数的指令，并确认平板电脑200是否返回显示参数。
如果平板电脑200返回显示参数，则执行S606；否则执行S605。
可以理解，在一些实施例中，平板电脑200向手机100发送的显示参数可以包括字体大小、字体样式、背景图案，背景颜色、控件属性等具体显示风格参数，例如，背景图案：涟漪，字体样式：宋体，字体大小：大，搜索栏：不可见(如在图3b所示的老人模式下，搜索栏1002不可见)等等。
而在另外一些实施例中，平板电脑200向手机100发送的显示参数可以仅包含一个标识，手机100上存储有各标识所对应的显示风格参数，例如，如下表1所示，其中，标识1对应的背景图案是涟漪，字体样式是宋体，背景颜色为白色无底纹；标识2对应的字体样式是楷体，字体大小是14，背景颜色为黑色；标识3对应的字体样式是华文新魏。
如下表1所示，不同的显示参数具有不同的种类、名称、标识，并对应不同的参数。
Figure PCTCN2021122792-appb-000001
表1
S605：手机100提示是否在无法完成一致性显示功能的情况下继续进行投屏。
例如，如图10所示，在手机100向平板电脑200发出获取平板电脑200的显示参数的指令后，如果手机100并未收到平板电脑200返回的显示参数。这时，手机100的屏幕中可以弹出一个提示框1014，提示用户无法完成一致性显示功能，是否继续进行多屏协同显示。如果用户选是，则执行S603，手机100将未修改显示风格的显示界面103投屏至平板电脑200，如果用户选择否，则手机100结束投屏，即终止将显示界面103投屏至平板电脑200的操作，并提示用户多屏协同显示结束，即执行S610，结束多屏协同显示。
可以理解，在另一些实施例中，如果用户选择否，手机100还可以重复执行S604，手机100可以再次向平板电脑200发出获取平板电脑200的显示参数的指令。
此外，可以理解，在另外一些实施例中，手机100可以在与平板电脑200建立通信连接之后，向平板电脑200发送获取显示参数的指令，手机100无需等到开启一致性显示模式后，才发送该获取指令。
此外，还可以理解的是，在另外一些实施例中，在手机100与平板电脑200通信连接之后，平板电脑200也可以主动向手机100发送显示参数，手机100无需向平板电脑200发送获取显示参数的指令。
S606：手机100基于获取的显示参数，通过显示系统服务101确定手机100是否具备显示参数所对应的显示功能。
如果手机具备这些功能，则创建显示风格修改后的投屏界面104，进入S608；如果不具备某些显示功能，则需要从服务器下载显示功能对应的配置文件，进入S607。
例如，手机100在获取了显示参数后，可以通过显示系统服务101在自身的存储器中查找与显示参数对应的显示功能的配置文件。例如，手机100从平板电脑200处获取的显示参数中包含：背景图案“涟漪”，则手机100的显示系统服务101可以在自身的存储器中查找背景图案“涟漪”的配置文件。
S607：手机100从服务器300获取手机100所不具备的显示功能所对应的配置文件。
例如，假如手机100接收到的显示参数包括的显示风格参数包括：背景图案“涟漪”以及字体“华文新魏”，其中，手机100的存储器中没有存储字体“华文新魏”，则手机100可以向服务器300发送获取请求，从服务器300接收字体“华文新魏”的配置文件，从而用于后续处理中。
S608：手机100创建与当前的显示界面103的显示内容相同的投屏界面104，基于获取的显示参数修改投屏界面104的显示风格。
可以理解，手机100可以通过各种方式创建投屏界面104，例如手机100可以通过创建不可见视图(View)、创建虚拟屏、或者以画中画的形式生成投屏界面104。在创建投屏界面104时，使得该即时通信APP在投屏界面中的显示内容与手机100当前的显示界面103中的即时通信APP一致。创建投屏界面104以及修改显示风格的具体技术细节将在下文进行详细介绍。
S609：手机100将投屏界面104投屏至平板电脑200的显示界面202的局部投屏区域内，平板电脑200在局部投屏区域内显示投屏界面104。
上述S601至S608中，手机100与平板电脑200，以及手机100与服务器300之间发送/返回的请求可以是socket请求(套接字请求)。socket请求用于无线网络或者有线网络中不同电子设备之间，不同电子设备的应用程序之间进行双向通信。
下面介绍在S608中，创建投屏界面104的几种方式。
方式一：通过创建不可见视图生成投屏界面
这里的投屏界面104可以是手机100通过显示系统服务101创建的当前显示界面103的不可见视图，手机100将该投屏界面104设置为不可见。在创建后，投屏界面104的显示内容与手机100屏幕上当前的显示界面103中的显示内容一致。之后，手机100通过显示系统服务101基于获取的平板电脑200的显示参数修改投屏界面104的显示风格。例如，手机100通过显示系统服务101修改投屏界面104中的即时通信APP的字体大小、字体样式、背景图案，背景颜色以及控件属性，或者主题模式等显示参数。
图11a至图11c描述了手机100在开启一致性显示模式的情况下，通过创建手机100当前显示界面103的不可见视图得到投屏界面104，并基于平板电脑200的当前的显示风格修改投屏界面104的显示风格的具体技术细节。
如图11a所示，手机100当前的显示界面103中显示的即时通信APP由多个控件组成，例如，包括标题栏1001、搜索栏1002以及通信栏目1003。其中，通信栏目1003中显示两个通信对象，这两个通 信对象分别是“通勤记录”、“工作群”。每个通信对象还包括：对象图标和通信内容。在图11a中，即时通信APP的背景颜色10011设置为浅灰色，通信栏目1003中的每个通信对象的通信内容的背景颜色10012设置为深灰色。
手机100从平板电脑200获取显示参数，该显示参数包括：背景颜色为白色。手机100创建一个与显示界面103相同的投屏界面104，将该投屏界面104中的即时通信APP的背景颜色10011以及通信栏目1003中通信对象的通信内容部分的背景颜色10012都修改为白色。最后，手机100将修改过显示风格的投屏界面104投屏至平板电脑200的显示界面202。
下面参考图11b中，手机100的当前的显示界面103中显示的即时通信APP除了包括标题栏1001、搜索栏1002以及通信栏目1003，其还设置了“涟漪”的背景图案10013。手机100从平板电脑200获取了显示参数，该显示参数包括：背景图案为默认背景图案。手机100通过创建一个与显示界面103相同的投屏界面104，将该投屏界面104中的即时通信APP中的背景图案修改为默认背景图案，即去掉“涟漪”的背景图案10013，再将修改过显示风格的投屏界面104投屏至平板电脑200的显示界面202。
最后参考图11c，与图11a和图11b不同的是，在图11c中，手机100的当前的显示界面103中显示的即时通信APP包括标题栏1001、搜索栏1002以及通信栏目1003，其中字符的字体样式10014为楷体，而平板电脑200的字体样式为宋体。因此，手机100将创建的投屏界面104中字符的字体样式10014修改为宋体后，将修改过显示风格的投屏界面104投屏至平板电脑200的显示界面202。
方式二：通过虚拟屏创建投屏界面
在另一实施例中，手机100可以在虚拟屏上创建与当前的显示界面103显示内容相同的投屏界面104，并将修改过显示风格的投屏界面104投屏至平板电脑200的显示界面202。
例如，手机100可以创建一个虚拟屏，手机100基于从平板电脑200处获取的字体大小、字体样式、字体颜色、图标大小、图标颜色、背景图案，背景颜色以及控件属性等显示参数创建并修改投屏界面104，并将其显示在虚拟屏中。该虚拟屏的屏幕尺寸、分辨率以及像素密度可以与手机100的当前的显示界面103相同。例如，在Android系统中，手机100可以通过将当前的显示界面103的屏幕尺寸、分辨率、像素密度等作为参数，使用Android系统的显示系统服务DisplayManager的createVirtualDisplay(String,int,int,int,Surface,int)的方法来创建虚拟屏。此外，在一些实施例中，为了不影响手机100上的显示界面103，可以设置虚拟屏为对用户不可见。而在另外一些实施例中，为了让用户确定修改后的显示界面的风格是否满足用户的要求，可以将虚拟屏设置为对用户可见，在用户确认该修改后，才向平板电脑200发送投屏界面104。
方式三：通过画中画的方式创建投屏界面
除了可以通过上述创建不可见视图和虚拟屏的形式来创建投屏界面104外，如图12所示，还可以在手机100中以类似画中画的形式，新建一个窗口1021，将修改过显示风格的投屏界面104显示在窗口1021内。该窗口1021与原来的显示界面103同时显示，然后将新建的窗口1021投屏到智能手表200的显示界面202。
上述手机100投屏平板电脑200的实施例中，平板电脑200用于接收投屏的局部投屏区域的大小大于或者等于手机100的屏幕的尺寸，而与之不同的是，如图3d所示，还存在将屏幕尺寸较大的电子设备(如手机100)投屏至屏幕较小的电子设备(如智能手表)的场景。
图13示出了图3d所示的场景下，手机100和智能手表200实现多屏协同显示的功能。具体地，如图13所示，包括：
S1301：手机100与智能手表200建立通信连接，并向智能手表200发出多屏协同请求。
S1302：手机100确认是否开启一致性显示模式，如果开启则进入S1304；如果没有开启则进入S1303。
S1303：手机100将未修改的显示界面103投屏至智能手表200的显示界面202的局部投屏区域中。
S1304：手机100向智能手表200发出获取智能手表200的显示参数的指令，并确认平板电脑200是否返回显示参数。
S1305：手机100提示是否在无法完成一致性显示功能的情况下继续进行投屏。如果用户选择否，则手机100结束投屏，即终止将显示界面103投屏至智能手表200的操作，并提示用户多屏协同显示结束，即执行S1310，结束多屏协同显示。
S1306：手机100基于获取的显示参数，通过显示系统服务101确定手机100是否具备显示参数所对应的显示功能。如果手机具备这些显示功能，则创建显示风格修改后的投屏界面104，进入S1308；如果不具备某些显示功能，则需要从服务器下载显示功能对应的配置文件，进入S1307。
S1307：手机100从服务器300获取手机100所不具备的显示功能所对应的配置文件。
上述S1301至S1307与图6中描述的S601至S607相同，这里不再详述。
S1308：手机100创建与当前的显示界面103的显示内容相同的投屏界面104，基于获取的显示参数修改投屏界面104的显示风格。
例如，手机100的显示界面103的字体样式是楷体，而智能手表200返回的显示参数包括字体样式是宋体，则手机100将投屏界面104的字体样式修改为楷体。在另一实施例中，显示参数还可以包括：字体大小、字体样式、背景图案，背景颜色以及控件等其他显示风格参数。这里的具体过程可以参考上文进行投屏界面的创建和显示风格的修改。
S1309：手机100将投屏界面104投屏至智能手表200的显示界面202的局部投屏区域内，智能手表200根据局部投屏区域的大小，以缩小的方式显示投屏界面104。
例如，智能手表200的屏幕的宽和高分别为100和200，智能手表200的屏幕内的局部投屏区域的大小为，宽50高100，手机100的宽和高分别为200和400，在手机100将投屏界面104投屏至智能手表200的显示界面202的局部投屏区域内后，投屏界面104的宽和高可以根据智能手表200的显示界面202的局部投屏区域的宽和高等比例地缩放为50和100。
上述S1309中描述的智能手表200根据局部投屏区域的大小通过缩放的方式显示投屏界面104，也可以在手机100处完成，例如，手机100在从智能手表200处获取显示参数的同时，手机100还可以同时获取智能手表200的显示界面202的局部投屏区域的尺寸。之后，手机100可以创建一个与智能手表200的局部投屏区域的尺寸相同的投屏界面104，在对投屏界面104修改了显示风格后，将与智能手表200的局部投屏区域的尺寸相同的投屏界面104投屏至智能手表200。
可以理解，在其他实施例中，手机100除了可以将投屏界面104缩小后投屏至第二电子设备200的屏幕，手机100还可以将投屏界面104放大后进行投屏。
例如，在第二电子设备200是智能电视200的情况下，智能电视200的屏幕的宽和高分别为1500和1000，智能电视200的屏幕内的局部投屏区域的大小为，宽300高600，手机100的宽和高分别为200和400，在手机100将投屏界面104投屏至智能电视200的屏幕后，投屏界面104的宽和高可以根据智能电视200的屏幕内的局部投屏区域的宽和高等比例地缩放为300和600。
此外，手机100还可以将显示界面103投屏至多个第二电子设备200，这时，手机100将为显示界面103创建多个投屏界面，将多个投屏界面分别投屏至多个第二电子设备200，同时为了将多个投屏界面进行区分，在创建投屏界面时，手机100对每个投屏界面配置一个投屏界面ID(Display Id)。从而 便于手机100在对多个第二电子设备200进行投屏时，通过投屏界面的投屏界面ID对投屏界面进行查找和管理。
参考图3e，下面说明手机100将显示界面103投屏至智能手表200-1和车机200-2的过程，与图6描述的过程的不同之处在于，手机100需要同时创建显示界面103的第一投屏界面105和第二投屏界面106。如图14所示，具体包括：
S1401：手机100与智能手表200-1和车机200-2通信连接，并向智能手表200和车机200-2发出多屏协同请求。
S1402：手机100确认是否开启一致性显示模式，如果开启则进入S1404；如果没有开启则进入S1403。
S1403：手机100将未修改的显示界面103投屏至智能手表200-1的显示界面202和车机200-2的显示界面204的局部投屏区域。
S1404：手机100向智能手表200-1和车机200-2分别发出获取显示参数的指令，并确认智能手表200-1和车机200-2是否返回显示参数。
S1405：手机100提示是否在无法完成一致性显示功能的情况下继续进行投屏。如果用户选择否，则手机100结束投屏，即终止将显示界面103投屏至智能手表200-1和车机200-2的操作，并提示用户多屏协同显示结束，即执行S1410，结束多屏协同显示。
S1406：手机100基于获取的显示参数，通过显示系统服务101确定手机100是否具备显示参数所对应的显示功能。如果手机具备这些功能，则创建显示风格修改后的第一投屏界面105和第二投屏界面106，进入S1408；如果不具备某些显示功能，则需要从服务器下载显示功能对应的配置文件，进入S1407。
S1407：手机100从服务器300获取手机100所不具备的显示功能所对应的配置文件。
上述S1401至S1407与图6中描述的S601至S607相同，这里不再详述。
S1408：手机100分别创建与当前的显示界面103的显示内容相同的第一投屏界面105和第二投屏界面106，基于智能手表200-1和车机200-2的不同显示参数分别修改第一投屏界面105和第二投屏界面106的显示风格。
例如，智能手表200-1和车机200-2的显示参数可以是：背景颜色为白色，字体样式为宋体，而这时手机100的显示界面103的显示风格是，背景颜色为灰色，字体样式为楷体，手机100通过显示系统服务101分别创建第一投屏界面105和第二投屏界面106，第一投屏界面105用于投屏至智能手表200-1，第二投屏界面106用于投屏至车机200-2。手机100通过显示系统服务101将第一投屏界面105和第二投屏界面106的显示风格统一修改为背景颜色为白色，字体样式为宋体。
S1409：手机100将第一投屏界面105投屏至智能手表200的显示界面202的局部投屏区域，将第二投屏界面106投屏至车机200-2的显示界面204的局部投屏区域。
图15根据本申请的另外一些实施例，示出了图2所示的屏幕协同系统进行屏幕协同显示的另一种方法流程图。具体地，如图15所示，包括：
S1501：第一电子设备和第二电子设备建立多屏协同连接。
建立多屏协同连接的方式请参考S601中，手机100与平板电脑200建立多屏协同连接的过程，例如，此处第一电子设备可以是手机100，第二电子设备可以是平板电脑200。手机100与平板电脑200进行通信连接，并向平板电脑200发出多屏协同请求。
此外，可以理解，第二电子设备也可以是图3e中的智能手表200-1或者是车机200-2。
S1502：第一电子设备显示第一界面，第一界面包括第一内容，第一界面具有第一显示参数。
例如，如图图3a所示，此处的第一界面可以是手机100的显示界面103，显示界面103中包括： 标题栏，搜索栏，通信栏目等，即为第一内容，同时，显示界面103中字符的字体为楷体，背景颜色为粉色，背景图案为有涟漪图案，也就是第一显示参数。
再例如，如图3e所示，手机100的显示界面103中的第一内容也可以包括联系人图标，联系人姓名，提示内容，取消按键和切换到语音按键等。这时，第一显示参数包括显示界面103中的字体为楷体，背景颜色为粉色等参数。
S1503：第二电子设备显示第二界面，第二界面包括第二内容，第二界面具有第二显示参数。
例如，如图3a所示，这里的第二界面可以是平板电脑200的显示界面202，显示界面202中包括：设置，耗电排行等，即为第二内容，同时，显示界面202中字符的字体为宋体，且背景颜色为白色，也就是第二显示参数。
再例如，如图3e所示，第二界面还可以是智能手表200-1的显示界面202，其包括：日期和时间等，即为第二内容。这时，第二显示参数包括智能手表200-1的显示界面202中，字符的字体为华文彩云，且背景颜色为白色。第二界面也可以是车机200-2的显示界面204，显示界面204中包括：音乐播放信息，音乐播放进步，音乐播放按钮等，即为第二内容。这时，第二显示参数包括车机200-2的显示界面204中字符的字体为宋体，且背景颜色为白色。
可以理解，上述步骤S1501至S1503的顺序不限于图示的顺序，可以是任意顺序，例如，可以是S1502、S1503、S1501的顺序，也可以是S1501、S1503、S1502的顺序，或着S1501、S1503、S1502同时进行。
S1504：第一电子设备向第二电子设备发送第三界面。
例如，如图图3a所示，第三界面可以是手机100生成的投屏界面104，手机100将投屏界面104内字体样式从楷体修改为宋体，将背景颜色修改为白色，背景图案从有涟漪图案修改为无涟漪图案，也就是修改为第二显示参数，然后将投屏界面104投屏至平板电脑200的显示界面202。
再例如，如图3e所示，第三界面可以是手机100生成的第一投屏界面105，手机100使用第二显示参数，如：字符的字体为华文彩云，且背景颜色为白色。修改第一投屏界面105。第三界面也可以是手机100生成的第二投屏界面106，手机100使用第二显示参数，如：字符的字体为宋体，且背景颜色为白色，修改第二投屏界面106。
S1505：响应于接收到的第三界面，第二电子设备显示第四界面，第四界面包括第二内容和第一窗口，第一窗口包括第一内容，第一窗口中的第一内容具有第二显示参数。
例如，如图3a所示，这里的第四界面，是平板电脑200的显示界面202，第一窗口是平板电脑200的显示界面202内的局部投屏区域。平板电脑200在接收到手机100的投屏界面104后，在显示界面202中除了显示设置，耗电排行等，还显示投屏界面104，也就是标题栏，搜索栏，通信栏目等，即为第一内容。并且，第一内容中字符的字体为宋体，且背景颜色为白色，无背景图案，也就是第二显示参数。
再例如，如图3e所示，这里的第四界面，可以是是智能手表200-1的显示界面202，智能手表200-1在接收到手机100的第一投屏界面105后，在显示界面202中使用第二显示参数，如：字符的字体为华文彩云，且背景颜色为白色，显示包含第一内容的第一投屏界面105。
这里的第四界面，还可以是车机200-2的显示界面204，车机200-2在接收到手机100的第二投屏界面106后，在显示界面204中使用第二显示参数，如：字体为宋体，且背景颜色为白色，显示包含的第一内容的第二投屏界面106。
