具体实施方式
以下描述中，为了说明而不是为了限定，提出了诸如特定***结构、技术之类的具体细节，以便透彻理解本申请实施例。然而，本领域的技术人员应当清楚，在没有这些具体细节的其它实施例中也可以实现本申请。在其它情况中，省略对众所周知的***、装置、电路以及方法的详细说明，以免不必要的细节妨碍本申请的描述。
应当理解，当在本申请说明书和所附权利要求书中使用时，术语“包括”指示所描述特征、整体、步骤、操作、元素和/或组件的存在，但并不排除一个或多个其它特征、整体、步骤、操作、元素、组件和/或其集合的存在或添加。
还应当理解，在本申请说明书和所附权利要求书中使用的术语“和/或”是指相关联列出的项中的一个或多个的任何组合以及所有可能组合，并且包括这些组合。
如在本申请说明书和所附权利要求书中所使用的那样，术语“如果”可以依据上下文被解释为“当...时”或“一旦”或“响应于确定”或“响应于检测到”。类似地，短语“如果确定”或“如果检测到[所描述条件或事件]”可以依据上下文被解释为意指“一旦确定”或“响应于确定”或“一旦检测到[所描述条件或事件]”或“响应于检测到[所描述条件或事件]”。
另外，在本申请说明书和所附权利要求书的描述中，术语“第一”、“第二”、“第三”等仅用于区分描述，而不能理解为指示或暗示相对重要性。
在本申请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。
本申请实施例提供的投屏方法可以应用于手机、平板电脑、可穿戴设备、车载设备、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本、个人数字助理(personal digital assistant，PDA)等电子设备上，本申请实施例对电子设备的具体类型不作任何限制。
投屏是指将一个电子设备的屏幕画面实时传递至另一个电子设备的屏幕进行显示的技术。
当前存在一些较为成熟的投屏方案，例如，适用于苹果移动操作***(iPhone Operation System，iOS)和麦金塔(Macintosh，Mac)***的隔空播放(AirPlay)技术、Wi-Fi联盟制定的Miracast协议、以及与Miracast协议同源的无线高清(WirelessDisplay，WiDi)技术等。
这些投屏方案可以将投屏端(发起投屏的电子设备，也可以称为源端，Source端)的完整的屏幕画面进行合成和编码，然后将编码后的图像发送至被投屏端(响应投屏的电子设备，也可以称为接收端，Sink端)。Sink端对编码后的图像进行解码，并以镜像的方式显示在屏幕上。
这些方案可以将Source端的完整的屏幕画面发送至Sink端的屏幕进行显示，但是，有的用户可能只想分享Source端的屏幕的部分内容，并不想将其他内容分享给Sink端。
因此，在现有的投屏方案中，存在投屏方式单一，而且被投屏端可能出现用户不想投屏的内容的问题。
有鉴于此，本申请实施例提供了一种投屏方法、装置、电子设备及计算机可读存储介质，可以使投屏区域准确地覆盖用户想要投屏的内容，解决了现有的投屏方案中，投屏方式单一，而且被投屏端可能出现用户不想投屏的内容的问题，具有较强的易用性和实用性。
首先，以图1所示的投屏***为例，该投屏***是本申请实施例提供的投屏方法适用的一种***。
如图1所示，该投屏***中包括至少一个第一设备101(图1中仅示出一个)和至少一个第二设备102(图1中仅示出一个)。
其中，第一设备101为发起投屏的电子设备，第二设备102为响应投屏的电子设备。
上述第一设备101和上述第二设备102均设置有无线通信模块。第一设备101可以通过本设备的无线通信模块以及预设的投屏协议与第二设备102的无线通信模块建立投屏连接103。
预设的投屏协议可以为AirPlay协议、Miracast协议、WiDi协议、数字生活网络联盟(DIGITAL LIVING NETWORK ALLIANCE，DLNA)协议等投屏协议中的任意一种。或者，预设的投屏协议也可以为厂商自定义的投屏协议。本申请实施例对投屏协议的具体类型不予限制。
当第一设备101与第二设备102建立了投屏连接103时，第一设备101可以响应于用户的操作，将用户想要分享的内容传递至第二设备102。
第二设备102接收到第一设备101传输的内容后，将上述内容显示在第二设备102的屏幕上，完成投屏操作。
以下，将根据图1所示的投屏***并结合具体的应用场景，对本申请实施例提供的投屏方法进行详细描述。
1、确定投屏内容。
当用户希望将第一设备显示的内容分享给第二设备时，用户可以执行内容选定操作。此时，第一设备可以响应于用户的内容选定操作，确定投屏内容，并执行投屏操 作。
上述内容选定操作的形式可以根据实际场景进行设置。例如，当第一设备设置有触控屏时，内容选定操作可以包括长按屏幕、点击屏幕、滑动屏幕等手势操作中的任意一种或多种的组合。当第一设备设置有鼠标、手写笔等辅助操作的配件设备时，内容选定操作可以包括点击配件设备、拖动配件设备等操作中的任意一种或多种的组合。
上述投屏内容可以包括文字、图片、网页控件等对象中的任意一种或多种的组合。
例如，请参阅图2，假设第一设备为手机。当用户想要分享手机当前显示界面中的文字时，用户可以对手机的屏幕进行操作，长按文字部分的内容。
此时，手机可以响应于用户的长按操作，显示内容选择框以及操作选项。内容选择框为图2中斜线填充区域。操作选项可以包括“复制”、“分享”、“全选”、“投屏”等选项。
如图3和图4所示，当用户拖动内容选择框时，手机可以响应于用户对内容选择框的拖动操作，向两侧扩展内容选择框的覆盖区域，框选相应的文字。
如图5所示，在用户完成对内容选择框的拖动操作之后，用户点击操作选项中的“投屏”选项。此时，手机可以响应于用户对操作选项中“投屏”选项的点击操作，将内容选择框当前框选的文字“测试文字测”确定为投屏内容。
又比如，请参阅图6、图7和图8，假设第一设备为台式电脑，该台式电脑配备有鼠标。
当用户想要分享台式电脑当前显示界面中的文字时，用户可以长按鼠标左键，并拖动鼠标。此时，台式电脑可以响应于用户对鼠标的点击和拖动操作，显示内容选择框，并调整内容选择框的覆盖区域(即图7和图8中斜线填充区域)，框选相应的文字。
如图8所示，用户在选中相应的文字之后，可以在内容选择框的覆盖区域内点击鼠标的右键。此时，台式电脑响应于用户的点击操作，显示操作选项。操作选项可以包括“复制”、“分享”、“全选”、“投屏”等选项。
然后，用户控制鼠标，左键点击“投屏”选项。此时，台式电脑响应于用户对操作选项中“投屏”选项的点击操作，将内容选择框当前框选的文字“测试文字测”确定为投屏内容。
又比如，请参阅图9，假设第一设备为手机。当用户想要分享手机当前显示界面中的图像时，用户可以长按想要分享的图像。
此时，手机可以响应于用户的长按操作，显示操作选项。操作选项可以包括“下载图像”、“分享图像”、“投屏图像”等选项。
然后，如图10所示，用户在选中了需要投屏的图像之后，可以点击操作选项中的“投屏图像”选项。此时，手机可以响应于用户对操作选项中“投屏图像”选项的点击操作，将上述被选中的图像确定为投屏内容。
2、建立投屏连接。
在第一设备基于内容选定操作确定了投屏内容之后，第一设备可以检测本设备是否已经与第二设备建立投屏连接。
在一些实施例中，第一设备可能检测到本设备已经与第二设备建立了投屏连接。 此时，第一设备可以跳过与第二设备建立投屏连接的操作。
在另一些实施例中，第一设备可能检测到本设备未与第二设备建立投屏连接。此时，第一设备可以执行搜索操作，查找周围可被投屏的电子设备，并展示被搜索到的电子设备的设备列表(即上述第一列表)。
当第一设备展示设备列表时，用户可以通过设备列表直观的查看到周围可被投屏的电子设备。然后，用户可以对上述设备列表执行选择操作，从设备列表展示的各个电子设备中选择第二设备。
当第一设备检测到用户的选择操作时，第一设备可以响应于上述选择操作，确定第二设备，并发送投屏请求至第二设备。
当第二设备接收到投屏请求时，第二设备可以根据预设的响应规则同意该投屏请求或拒绝该投屏请求；或者，第二设备也可以响应于用户对第二设备的操作，同意该投屏请求或拒绝该投屏请求。
如果第二设备同意上述投屏请求，则第一设备与第二设备建立投屏连接，第一设备创建虚拟显示窗口。虚拟显示窗口用于管理投屏图像。
如果第二设备拒绝上述投屏请求，则第一设备停止投屏操作，或者，第一设备也可以重新展示上述列表，以便用户重新选择第二设备。
预设的响应规则可以根据实际场景进行设置。例如，在一些实施例中，预设的响应规则可以设置为：拒绝黑名单中的电子设备发送的投屏请求，默认通过黑名单以外的电子设备发送的投屏请求。或者，在另一些实施例中，预设的响应规则也可以设置为其他条件。本申请实施例对预设的响应规则的具体条件不予限制。
例如，请参阅图10，假设第一设备为手机。手机响应于用户对当前显示界面中某张图像的长按操作，显示操作选项。操作选项可以包括“下载图像”、“分享图像”、“投屏图像”等选项。
用户想要将被选中的图像投屏至其他电子设备，点击了“投屏图像”的选项。然后，手机响应于用户对操作选项中“投屏图像”选项的点击操作，将上述被选中的图像确定为投屏内容。
之后，手机检测本设备是否已经与第二设备建立了投屏连接。
如图11所示，当手机检测到本设备未与第二设备建立投屏连接时，手机执行搜索操作，搜索周围可被投屏的电子设备，并显示搜索界面。
如图12所示，手机在完成搜索操作之后，生成设备列表，并将设备列表显示在手机屏幕当前的显示界面上。设备列表中包括被搜索到的电子设备的标识。
假设设备列表中包括“智能电视”、“笔记本电脑”和“台式电脑”这三个被搜索到的电子设备。用户查看了上述列表之后，点击了“智能电视”的选项，想要将上述投屏内容投屏至智能电视。
此时，如图13所示，手机响应于用户对“智能电视”选项的点击操作，发送投屏请求至智能电视。
智能电视在接收到投屏请求后，检测到发送投屏请求的手机不在黑名单中，则默认同意投屏请求，与手机建立投屏连接。
或者，智能电视也可以在智能电视的屏幕上显示提示框，在提示框中询问用户是 否同意投屏。如果用户点击了提示框中“是”的选项，则智能电视同意上述投屏请求，与手机建立投屏连接。如果用户点击了提示框中“否”的选项，则智能电视拒绝上述投屏请求，返回错误信息至手机。
3、生成投屏图像。
在建立了投屏连接之后，第一设备可以根据投屏内容生成投屏图像，并通过上述投屏连接将投屏图像传递至第二设备进行显示。
在一些实施例中，第一设备可以通过预设的控件获取被选中的投屏内容。例如，当被选中的投屏内容为文字时，第一设备可以通过文字控件获取到被选中的文字；当被选中的投屏内容为图像时，第一设备可以通过图像控件获取到被选中的图像。
在获取到投屏内容之后，第一设备可以根据第二设备的投屏配置信息对上述投屏内容进行排版，得到第一内容。
上述投屏配置信息的内容可以根据实际需求进行设置。例如，在一些实施例中，上述投屏配置信息可以包括第二设备的屏幕分辨率、屏幕尺寸、字体、字号、颜色等信息中的一种或多种。
并且，上述投屏配置信息的获取时机也可以根据实际需求进行设置。例如，在一些实施例中，第一设备可以在与第二设备建立了投屏连接之后，立即获取第二设备的投屏配置信息；或者，在另一些实施例中，第一设备也可以在对投屏内容进行排版时，获取第二设备的投屏配置信息；或者，在另一些实施例中，第一设备也可以在其他时机获取第二设备的投屏配置信息。本申请实施例对第一设备获取第二设备的投屏配置信息的时机不予限制。
第一设备在生成第一内容之后，可以对第一内容对应的图形数据进行渲染和合成，得到投屏图像。
第一设备在得到投屏图像之后，可以根据预设的投屏协议对投屏图像进行编码，得到编码数据，并通过上述投屏连接将编码数据传递至第二设备。
第二设备接收到编码数据之后，根据预设的投屏协议对编码数据进行解码，得到投屏图像，将投屏图像显示在第二设备的屏幕上，完成本次投屏操作。
例如，假设第一设备为手机，第二设备为智能电视，手机的操作***为安卓操作***。如图14和图15所示，斜线填充部分为内容选择框，内容选择框内的文字和图像为被用户选中的投屏内容。
在用户点击了操作选项中的“投屏”选项之后，手机可以通过投屏服务创建虚拟显示窗口(display)和该虚拟显示窗口对应的活动管理(Activity)。
然后，投屏服务通过文字控件(TextView)将被选中的文字传递至Activity，通过图像控件(ImageView)将被选中的图像传递至Activity。
并且，Activity可以通过局域网(Local Area Network，LAN)服务获取第二设备的投屏配置信息。投屏配置信息可以包括第二设备的屏幕尺寸、第二设备的显示分辨率等信息。
如图16所示，Activity根据第二设备的投屏配置信息调整虚拟显示窗口的窗口尺寸，并根据第二设备的投屏配置信息对获取到投屏内容进行排版，调整文字和图像的位置、大小等，从而得到排版后的第一内容。
之后，Activity可以将第一内容的图形数据传递至图形处理器(Graphics Processing Unit，GPU)进行渲染，并将渲染后的图形数据传递至虚拟显示窗口。
虚拟显示窗口将渲染后的图形数据传递至窗口合成服务(SurfaceFlinger)，窗口合成服务对渲染后的图形数据进行合成，得到投屏图像。
如图17所示，在得到投屏图像之后，投屏服务可以根据预设的投屏协议对投屏图像进行编码，得到编码数据，并将编码数据通过上述投屏连接传递至智能电视。
智能电视根据预设的投屏协议对编码数据进行解码，得到投屏图像，将投屏图像显示在智能电视的屏幕上，完成本次的投屏操作。
在另一些实施例中，第一设备可以获取投屏内容所在的目标图层。
例如，假设第一设备当前显示的界面由应用程序A对应的图层a、应用程序B对应的图层b和应用程序C对应的图层c合成得到，被选中的投屏内容为应用程序B和应用程序C的内容，则第一设备可以先获取图层b和图层c。
然后，第一设备可以对目标图层进行合成操作，得到投屏图像。
例如，假设第一设备为手机，第二设备为智能电视，手机的操作***为安卓操作***。
假设手机当前显示的界面为图18所示的内容。如图19所示，手机当前显示的界面由图层a、图层b和图层c合成得到。
如图20所示，手机可以响应于用户的操作，从手机当前显示的界面中确定投屏内容(即图20中斜线填充区域)。
在用户点击了操作选项中的“投屏”选项之后，手机可以通过投屏服务创建虚拟显示窗口(display)和该虚拟显示窗口对应的活动管理(Activity)。
然后，投屏服务可以将投屏内容对应的目标图层(即图层b)传递至Activity。
Activity将图层b传递至虚拟显示窗口。虚拟显示窗口将图层b传递至窗口合成服务(SurfaceFlinger)，窗口合成服务对图层b进行合成，得到投屏图像。
如图21所示，在得到投屏图像之后，投屏服务可以根据预设的投屏协议对投屏图像进行编码，得到编码数据，并将编码数据通过上述投屏连接传递至智能电视。
智能电视根据预设的投屏协议对编码数据进行解码，得到投屏图像，将投屏图像显示在智能电视的屏幕上，完成本次的投屏操作。
由于同一图层的内容属于同一应用程序，可以认为同一图层的内容的关联性较强。因此，第一设备通过上述方法生成投屏图像时，投屏图像中仅包含投屏内容以及与投屏内容强关联的内容，没有无关图层的干扰，可以避免投屏内容被遮挡，提高了投屏的准确性。
在另一些实施例中，第一设备可以获取第一设备当前显示的界面的显示图像以及投屏内容的位置信息。
第一设备可以根据投屏内容的位置信息确定投屏内容所在的区域，即目标区域。
然后，第一设备可以对显示图像执行截取操作，截取显示图像的目标区域的图形数据，即截取图形数据。
然后，第一设备对上述截取图形数据进行合成，得到投屏图像。
例如，假设第一设备为手机，第二设备为智能电视，手机的操作***为安卓操作 ***，手机当前显示的界面为图18所示的内容。
如图20所示，手机可以响应于用户的操作，从手机当前显示的界面中确定投屏内容(即图20中斜线填充区域)。
在用户点击了操作选项中的“投屏”选项之后，手机可以通过投屏服务创建虚拟显示窗口(display)和该虚拟显示窗口对应的活动管理(Activity)。
然后，投屏服务可以将手机当前显示的界面的显示图像和投屏内容对应的位置信息传递至Activity。
如图22所示，Activity在获取到显示图像和投屏内容对应的位置信息之后，根据上述位置信息对显示图像进行截取操作，得到目标区域的截取图形数据。
之后Activity将截取图形数据传递至虚拟显示窗口。虚拟显示窗口将截取图形数据传递至窗口合成服务(SurfaceFlinger)，窗口合成服务对区域图形数据进行合成，得到投屏图像。
在得到投屏图像之后，投屏服务可以根据预设的投屏协议对投屏图像进行编码，得到编码数据，并将编码数据通过上述投屏连接传递至智能电视。
智能电视根据预设的投屏协议对编码数据进行解码，得到投屏图像，将投屏图像显示在智能电视的屏幕上，完成本次的投屏操作。
第一设备通过上述方法生成投屏图像时，目标区域是根据投屏内容的位置信息自动确定的，不是用户手动框选的。因此，投屏图像只包含投屏内容所在区域的内容，不包含投屏内容所在区域以外的内容，从而避免将用户不想分享的内容投屏至第二设备。
在另一些实施例中，第一设备可以先获取被选中的投屏内容所在的目标图层。
例如，假设第一设备当前显示的界面由应用程序A对应的图层a、应用程序B对应的图层b和应用程序C对应的图层c合成得到，被选中的投屏内容为应用程序B的内容，则第一设备可以先获取图层b。
在获取到目标图层之后，第一设备可以获取被选中的投屏内容的位置信息，根据投屏内容的位置信息对目标图层进行截取操作，得到目标区域的区域图形数据。目标区域为投屏内容所在的区域。
在得到区域图形数据之后，第一设备可以对区域图形数据进行合成，得到投屏图像。
在得到投屏图像之后，第一设备可以根据预设的投屏协议对投屏图像进行编码，得到编码数据，并通过上述投屏连接将编码数据传递至第二设备。
第二设备接收到编码数据之后，根据预设的投屏协议对编码数据进行解码，得到投屏图像，将投屏图像显示在第二设备的屏幕上，完成本次投屏操作。
例如，假设第一设备为手机，第二设备为智能电视，手机的操作***为安卓操作***。
假设手机当前显示的界面为图18所示的内容。如图19所示，手机当前显示的界面由图层a、图层b和图层c合成得到。
如图20所示，手机可以响应于用户的操作，从手机当前显示的界面中确定投屏内容(即图20中斜线填充区域)。
在用户点击了操作选项中的“投屏”选项之后，手机可以通过投屏服务创建虚拟显示窗口(display)和该虚拟显示窗口对应的活动管理(Activity)。
然后，投屏服务可以将投屏内容对应的目标图层(即图层b)以及投屏内容对应的位置信息传递至Activity。

4、多次投屏。
在用户完成了投屏操作之后，如果还需要执行新的投屏操作，则用户可以重新执行内容选定操作，第一设备根据用户的内容选定操作确定新的投屏内容。
之后，第一设备可以参照第3节所描述的内容，根据新的投屏内容进行图像截取和合成操作，生成新的投屏图像。
或者，第一设备也可以根据新的投屏内容生成新的第一内容，并根据新的第一内容确定新的投屏图像。
在一些可能的实现方式中，当第一设备在生成新的第一内容时，第一设备可以替换、覆盖或清除前一次投屏操作生成的第一内容，仅对本次选中的投屏内容进行处理。
此时，第一设备可以根据第二设备的投屏配置信息，对本次选中的投屏内容进行排版，得到本次投屏操作对应的第一内容。
然后，第一设备对新的第一内容进行渲染和合成，得到新的投屏图像，并通过上述投屏连接将新的投屏图像传递至第二设备进行显示。

此时，第一设备可以根据第二设备的投屏配置信息，对前一次投屏操作的第一内容和本次选中的投屏内容进行排版，得到新的第一内容。
或者，由于前一次投屏操作的第一内容已根据第二设备的投屏配置信息进行排版，所以，第一设备也可以根据第二设备的投屏配置信息对本次选中的投屏内容进行排版，并将排版后的投屏内容与前一次投屏操作生成的第一内容进行组合，得到新的第一内容。
在得到新的第一内容之后，第一设备对新的第一内容进行渲染和合成，得到新的投屏图像，并通过上述投屏连接将新的投屏图像传递至第二设备进行显示。
例如，请参阅图29，假设第一设备为手机。当用户想要再次投屏，并通过内容选定操作选中了新的投屏内容(即图27中斜线填充区域的文字)时，手机可以显示操作选项。操作选项可以包括“复制”、“分享”、“全选”、“新建投屏”、“合并投屏”等选项。
当用户点击“合并投屏”的选项时，手机可以响应于用户的操作，不清除前一次投屏的第一内容。

第二设备在检测到投屏连接断开时，可以取消显示投屏图像，或者，第二设备也可以继续显示投屏图像。
例如，请参阅图33，假设第一设备为手机，第二设备为智能电视。手机与智能电视之间建立有投屏连接。
当用户想要结束投屏时，可以下拉手机的操作栏。手机的操作栏中可能包括“无线网络”、“蓝牙”、“移动数据”、“静音”、“无线投屏”等操作选项。
然后，用户可以点击“无线投屏”的选项。如图34所示，当手机检测到用户对“无线投屏”的点击操作时，关闭投屏功能，停止投屏服务，断开与第二设备的投屏连接。
当智能电视检测到投屏连接断开时，智能电视可以继续显示最后一次接收到的投屏图像，或者，智能电视也可以取消显示最后一次接收到的投屏图像，显示待机界面。
或者，在另一些可能的实现方式中，用户也可以在第二设备执行结束投屏操作。当第二设备检测到结束投屏操作时，第二设备断开与第一设备的投屏连接。在断开投屏连接之后，第二设备可以取消显示投屏图像，或者，第二设备也可以继续显示投屏图像。

在另一些可能的实现方式中，除了用户主动结束投屏操作以外，第一设备和/或第二设备也可以设置有结束投屏操作的判定规则。
当满足上述判定规则的条件时，第一设备或第二设备可以自动结束投屏操作，断开投屏连接。
上述判定规则可以根据实际需求进行设置。例如，在一些实施例中，上述判定规则可以与闲置时长相关。闲置时长为当前时间与触发时间的时间间隔，触发时间为最近一次第一设备发送投屏图像时间或最近一次第二设备接收到投屏图像的时间。当第一设备或第二设备检测到闲置时长大于或等于预设时长阈值时，第一设备或第二设备可以自动结束投屏操作，断开投屏连接。在另一些实施例中，上述判定规则可以与投屏次数有关。投屏次数为第一设备发送投屏图像的数量或第二设备接收投屏图像的数量。当第一设备或第二设备检测到投屏次数大于或等于预设次数阈值时，第一设备或第二设备可以自动结束投屏操作，断开投屏连接。
为了便于理解，以下将结合具体的应用场景对上述投屏方法进行详细描述：
请参阅图35和图36，假设第一设备为手机。在初始时刻，手机未与其他电子设备建立投屏连接。

手机响应于用户的长按操作，显示内容选择框和操作选项。操作选项中包括“复制”、“分享”、“全选”、“投屏”这四个选项。
在手机显示了内容选择框之后，用户拖拉内容选择框两侧的调整光标，调节内容选择框的覆盖区域，使内容选择框覆盖“测试文字”这四个字。
然后，用户点击“投屏”选项。手机响应于用户的点击操作，将手机当前的显示界面(即第一显示界面)中被内容选定操作选中的内容确定为投屏内容。
并且，手机检测当前是否已经与其他电子设备建立投屏连接。
如图37所示，手机检测到当前未与其他电子设备建立投屏连接，则手机执行搜索操作，并显示第一列表。第一列表为手机搜索到的可被投屏的电子设备的设备列表。
假设第一列表中包括“智能电视”、“笔记本电脑”和“平板电脑”这三个被搜索到的电子设备。用户在查看了设备列表之后，可以执行选择操作，从第一列表中选择“智能电视”作为第二设备。
此时，手机可以响应于用户对第一列表的选择操作，从被扫描到的电子设备中确定第二设备，将智能电视设置为第二设备。
如图38所示，在确定了第二设备之后，手机向智能电视发送投屏请求。智能电视在接收到投屏请求后，检测到手机为可信任设备，则同意了该投屏请求，手机和智能电视建立投屏连接。
如图39所示，在建立投屏连接之后，手机通过投屏连接获取智能电视的投屏配置信息，并根据投屏配置信息对上述投屏内容进行排版，得到第一内容。
在得到第一内容之后，手机通过图形处理器对第一内容对应的图形数据进行渲染，并通过窗口合成器对渲染后的图形数据进行合成，得到投屏图像。
然后，手机根据预设投屏协议对投屏图像进行编码，得到编码数据，并向智能电视发送编码数据。
如图40所示，智能电视在接收到编码数据之后，根据预设投屏协议对编码数据进行解码，得到投屏图像，将投屏图像显示在本设备的屏幕上。
请参阅图41，假设用户在浏览新的显示界面的过程，想要将新的内容分享到智能电视。此时，用户可以重新执行内容选定操作，确定新的投屏内容(即图39中斜线填充区域选中的图像)。
手机可以响应于用户的内容选定操作，显示操作选项。手机提供的操作选项包括“复制”、“分享”、“全选”、“新建投屏”、“合并投屏”这五个选项。
当用户点击“合并投屏”选项时，手机将当前内容选择框选定的文字和图像作为新的投屏内容。并且，手机检测到已经与智能电视建立了投屏连接，所以手机跳过建立投屏连接的流程。
如图42所示，手机根据智能电视的投屏配置信息对新的投屏内容进行排版，并将排版后的投屏内容与上一次投屏操作的第一内容合并，将排版后的投屏内容续接在上一次投屏操作的第一内容的尾部，得到新的第一内容。
然后，手机通过图形处理器对新的第一内容的图形数据进行渲染，并通过窗口合成器对渲染后的图形数据进行合成，得到新的投屏图像。
如图43所示，手机根据预设投屏协议对新的投屏图像进行编码，得到新的编码数据，并向智能电视发送新的编码数据。
智能电视在接收到新的编码数据之后，根据预设投屏协议对新的编码数据进行解码，得到新的投屏图像，将新的投屏图像替换上一次接收到的投屏图像，将新的投屏图像显示在本设备的屏幕上。
综上，在本申请实施例提供的投屏方法中，用户可以通过内容选定操作自行选定投屏内容，第一设备响应于用户的内容选定操作，确定投屏内容，根据投屏内容生成投屏图像。第一设备生成的投屏图像仅包含被内容选定操作选中的内容，不包含其他未被选中的内容，用户可以针对性地进行投屏，从而避免投屏图像中出现用户不想投屏的内容。
