本申请要求在2021年09月27日提交中国专利局、申请号为202111133943.8、申请名称为“一种显示方法与电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电子技术领域，尤其涉及一种显示方法与电子设备。
背景技术
投屏技术是一种时下正在兴起的技术，是指一个电子设备可以将其显示屏上的显示界面投屏到另一个电子设备上显示。比如，手机上的文档界面可以投屏在笔记本电脑或平板电脑上显示，等等。
以笔记本电脑向平板电脑投屏为例，如图1，笔记本电脑上显示第一界面。当笔记本电脑检测到向平板电脑投屏(如，镜像投屏)操作时，向平板电脑发送第一界面的显示信息，平板电脑(处于横屏)显示第一界面。由于平板电脑具有屏幕旋转功能，用户操作平板电脑时可能会将平板电脑从横屏切换到竖屏。继续如图1，当平板电脑从横屏切换到竖屏时，为了适配竖屏显示，平板电脑上投屏来的第一界面缩小。这样，平板电脑上会出现黑屏区域，而且，第一界面缩小时用户查看起来比较费劲，体验较差。
发明内容
本申请的目的在于提供了一种显示方法与电子设备，用于提升投屏体验。
第一方面，提供一种显示方法，应用于包括第一电子设备和第二电子设备的***，所述方法包括：所述第一电子设备响应于第一操作，将所述第一电子设备中第一应用的第一界面的显示信息发送给所述第二电子设备；所述第二电子设备显示所述第一界面；所述第二电子设备响应于屏幕旋转操作，向所述第一电子设备发送指令，所述指令用于指示所述第二电子设备的屏幕旋转方向，所述屏幕旋转方向包括从横屏切换到竖屏或从竖屏切换到横屏；所述第一电子设备响应于所述指令，向所述第二电子设备发送所述第一应用的第二界面的显示信息；所述第二界面的显示信息多于或少于所述第一界面的显示信息，和/或，所述第二界面与所述第一界面的显示信息布局方式不同；所述第二电子设备显示所述第二界面。
也就是说，当主设备(即第一电子设备)向目标设备(即第二电子设备)投屏后，投屏到目标设备上的界面可以随着目标设备的屏幕旋转而变化，这种变化可以包括投屏到目标设备上的界面中显示信息的增加、减少、布局方式的调整等等，总之投屏到目标设备上的界面可以适配目标设备的屏幕旋转，提升投屏体验。
在一种可能的设计中，所述第二电子设备的屏幕旋转方向为从横屏切换为竖屏的情况下，所述第二界面上的显示信息多于所述第一界面的显示信息，和/或，所述第二界面与所 述第一界面的显示信息布局方式不同；所述第二电子设备的屏幕旋转方式为从竖屏切换到横屏的情况下，所述第二界面上的显示信息少于所述第一界面的显示信息，和/或，所述第二界面与所述第一界面的显示信息布局方式不同。
示例性的，目标设备(即第二电子设备)可以从横屏切换到竖屏或从竖屏切换到横屏，在从横屏切换到竖屏时，投屏到目标设备上的界面中显示信息增加或者显示信息布局调整以适配竖屏显示，在从竖屏切换到横屏时，投屏到目标设备的界面中显示信息减少或布局调整已适配横屏显示。总之投屏到目标设备上的界面可以适配目标设备的屏幕旋转，提升投屏体验。
在一种可能的设计中，所述第二界面上的显示信息多于所述第一界面的显示信息，包括：所述第二界面包括所述第一界面的全部显示信息，还包括第三界面的部分或全部显示信息，所述第三界面包括：所述第一界面的下一界面、上一界面、***默认界面或用户指定界面中的至少一种。
也就是说，当目标设备(即第二电子设备)从横屏切换到竖屏时，投屏在目标设备上的界面中的显示信息增多，可以增加下一界面或上一界面的显示信息等，这样不仅可以适配目标设备的屏幕旋转，还可以让用户在目标设备上查看到主设备的更多的显示信息，体验较好。
在一种可能的设计中，所述第二界面与所述第一界面的显示信息布局方式不同，包括：在所述第二电子设备的屏幕旋转方向为从横屏切换为竖屏的情况下，所述第一界面包括第一显示信息和第二显示信息且所述第一显示信息与所述第二显示信息在水平方向上平铺显示；所述第二界面中包括所述第一显示信息和所述第二显示信息且所述第一显示信息与所述第二显示信息在竖直方向上平铺显示；在所述第二电子设备的屏幕旋转方向为从竖屏切换到横屏的情况下，所述第一界面包括第一显示信息和第二显示信息且所述第一显示信息和所述第二显示信息在竖直方向上平铺显示；所述第二界面中包括所述第一显示信息和所述第二显示信息且所述第一显示信息与所述第二显示信息在水平方向上平铺显示。
举例来说，目标设备(即第二电子设备)处于横屏时，目标设备上由主设备投屏来的界面中显示信息A在左，显示信息B在右。当目标设备从横屏切换到竖屏时，投屏来的界面中显示信息A在上，显示信息B在下。通过这种方式，投屏到目标设备上的界面中的显示信息的布局方式可以随着目标设备的屏幕旋转而变化，以适配目标设备的屏幕旋转。
在一种可能的设计中，所述第一电子设备响应于第一操作，将所述第一电子设备中第一应用的第一界面的显示信息发送给所述第二电子设备，包括：所述第一电子设备显示所述第一界面；所述第一电子设备响应于所述第一操作，判断所述第一电子设备与所述第二电子设备的屏幕显示方向是否一致；在所述第一电子设备与所述第二电子设备的屏幕显示方向一致的情况下，将所述第一界面发送给所述第二电子设备。
也就是说，在本申请实施例中，主设备(即第一电子设备)向目标设备(即第二电子设备)投屏之前，可以判断目标设备与主设备的屏幕显示方向是否一致，如果一致，则主设备当前界面(即第一界面)可以投屏到目标设备上。比如，主设备当前是横屏且显示界面1，如果目标设备与主设备屏幕显示方向一致，那么主设备可以将界面1投屏到目标设备上，因为界面1已适配横屏显示。
在一种可能的设计中，在所述第一电子设备与所述第二电子设备的屏幕显示方向不一致的情况下，将所述第一应用的第四界面发送给所述第二电子设备；其中，所述第四界面 的显示信息多于或少于所述第一界面的显示信息，和/或，所述第四界面与所述第一界面的显示信息布局方式不同。
也就是说，主设备(即第一电子设备)向目标设备(即第二电子设备)投屏之前，可以判断目标设备与主设备的屏幕显示方向是否一致，如果一致，则主设备当前界面(即第一界面)可以投屏到目标设备上。如果不一致，主设备当前界面需要调整到适配目标设备的屏幕显示方向的界面(即第四界面)，然后将该界面投屏到目标设备上。通过这种方式，主设备向目标设备投出的首个界面就可以适配目标设备的屏幕显示方向，用户体验较好。
在一种可能的设计中，在所述第一电子设备与所述第二电子设备的屏幕显示方向不一致的情况下，将所述第一应用的第四界面发送给所述第二电子设备，包括：
在所述第一电子设备处于横屏、所述第二电子设备处于竖屏的情况下，所述第四界面的显示信息多于所述第一界面，和/或，所述第一界面包括第三显示信息和第四显示信息且所述第三显示信息与所述第四显示信息在水平方向上平铺显示，所述第四界面中包括所述第三显示信息和所述第四显示信息且所述第三显示信息与所述第四显示信息在竖直方向上平铺显示；
在所述第一电子设备处于竖屏、所述第二电子设备处于横屏的情况下，所述第四界面的显示信息少于所述第一界面，和/或，所述第一界面包括第三显示信息和第四显示信息且所述第三显示信息和所述第四显示信息在竖直方向上平铺显示，所述第四界面中包括所述第三显示信息和所述第四显示信息且所述第三显示信息与所述第四显示信息在水平方向上平铺显示。
举例来说，主设备(即第一电子设备)处于横屏、目标设备(即第二电子设备)处于竖屏。主设备显示第一界面，第一界面上显示信息A在左，显示信息B在右。由于目标设备处于竖屏，所以主设备向目标设备投屏的是第二界面，第二界面上显示信息A在上，显示信息B在下。通过这种方式，主设备向目标设备投出的首个界面就可以适配目标设备的屏幕显示方向，用户体验较好。
在一种可能的设计中，所述第一电子设备响应于第一操作，将所述第一电子设备中第一应用的第一界面的显示信息发送给所述第二电子设备，包括：所述第一电子设备响应于所述第一操作，创建第一虚拟显示器VD，所述第一VD的屏幕显示方向与所述第二电子设备的当前屏幕显示方向一致；所述第一电子设备将所述第一应用转移到所述第一VD中运行；所述第一应用在所述第一VD中显示所述第一界面；所述第一VD将所述第一界面发送给所述第二电子设备。
在本申请实施例中，因为第一VD与目标设备的屏幕显示方向一致，第一应用在第一VD中运行时，可以根据第一VD的屏幕显示方向调整其显示界面，比如显示第一界面，然后第一VD将第一界面投屏到目标设备上。这样可以保证第一应用投屏到目标设备上的界面能够适配目标设备的屏幕显示方向，因为第一VD的屏幕显示方向与目标设备的屏幕显示方向一致。
在一种可能的设计中，所述第一电子设备响应于所述指令，向所述第二电子设备发送所述第一应用的第二界面的显示信息，包括：所述第一电子设备响应于所述指令，调整所述第一VD的屏幕显示方向与所述第二电子设备旋转后的屏幕显示方向一致；所述第一应用响应于所述第一VD的屏幕显示方向的调整，将所述第一界面调整为所述第二界面；所述第一VD将所述第二界面发送给所述第二电子设备。
也就是说，第一VD的屏幕显示方向随着目标设备的屏幕显示方向的变化而变化，当第一VD的屏幕显示方向变化时，运行在第一VD中的第一应用的界面适应性调整(比如，从第一界面调整为第二界面)，然后第一VD将调整后的界面投屏到目标设备上，这样可以保证投屏界面随着目标设备的屏幕显示方向的变化而变化。
在一种可能的设计中，所述方法还包括：所述第一电子设备响应于第一操作，将所述第一电子设备中第一应用的第一界面的显示信息发送给所述第二电子设备之后，所述方法还包括：所述第一电子设备显示第二应用的界面；或者，显示所述第一界面。
也就是说，主设备投出第一应用的第一界面之后可以显示第二应用的界面，或者显示第一界面。如果主设备投出第一应用的第一界面之后显示第二应用的界面称之为应用投屏，如果主设备投出第一应用的第一界面之后，显示第一界面称之为镜像投屏。因此，本申请的技术方案可以适用于应用投屏也可以适用于镜像投屏。

具体实施方式
以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
(1)应用程序(application，简称app)，简称应用，为能够实现某项或多项特定功能的软件程序。通常，电子设备中可以安装多个应用，例如，即时通讯类应用、视频播放类应用、音频类应用、图像拍摄类应用等等。其中，即时通信类应用，例如可以包括短信应用、畅连应用、

Figure PCTCN2022117647-appb-000006
Figure PCTCN2022117647-appb-000007
等等。以下实施例中提到的应用，可以是电子设备出厂时已安装的应用，也可以是用户在使用电子设备的过程中从网络下载或其他电子设备获取的应用。
(2)本申请实施例涉及的至少一个，包括一个或者多个；其中，多个是指大于或者等于两个。另外，需要理解的是，在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为明示或暗示相对重要性，也不能理解为明示或暗示顺序。
本申请实施例提供的显示方法适用于投屏场景。一般来说，投屏场景中包括发送端和接收端。发送端将显示信息发送给接收端进行显示。为了方便描述，本文将发送端称为主设备，将接收端称为目标设备。当然，除了主设备和目标设备之外，发送端和接收端还可以有其它称呼，比如，发送端是主动投屏设备，接收端是被动投屏设备；或者，发送端是主设备，接收端是辅设备；或者，发送端是源设备，接收端是目标设备；或者，发送端是第一电子设备，接收端是第二电子设备等等，本申请对此不作限定。其中，发送端和接收端的角色可以互换，即，发送端可以向接收端投屏，对应的，所述接收端也可以向所述发送端投屏。在本申请实施例中，接收端是能够进行屏幕旋转(如，横、竖屏切换)的设备，比如平板电脑、手机等。发送端可以具有屏幕旋转功能，也可以没有屏幕旋转功能。比如，发送端包括手机、平板电脑、PC、手机、手表等等。为了方便描述，下文主要以发送端是笔记本电脑或手机、接收端是平板电脑为例进行介绍。
投屏技术包括镜像投屏和应用投屏。
镜像投屏，是指发送端将本机显示屏上当前显示信息发送给接收端，接收端显示所述显示信息。这样的话，发送端和接收端可展示相同的画面，换言之，发送端当前显示什么样的内容就向接收端投屏什么样的内容。示例性的，请参见图2，为镜像投屏的过程的示意图。发送端(如，笔记本电脑)前台显示第一应用的界面A。此时，若发送端检测到向接收端(如，平板电脑)镜像投屏的操作(将在后文介绍)，响应于该操作，发送端将前台显示信息发送给平板电脑。平板电脑上显示所述显示信息(如，第一应用的界面A)。当发送端前台显示信息发生变化，比如从界面A切换为界面B；对应的，接收端上的显示信息也变化，即从界面A切换为界面B。这种投屏技术，可以理解为，接收端显示屏是发送 端显示屏的镜像屏。
应用投屏与镜像投屏不同。简单来说，应用投屏场景中，接收端上由发送端投屏来的显示信息可以与发送端前台正在显示的显示信息不同。示例性的，请参见图3，为应用投屏过程的示意图。发送端(比如笔记本电脑)上显示第一应用的界面。此时，若发送端检测到向接收端(如，平板电脑)应用投屏的操作(将在后文介绍)，将第一应用投屏到平板电脑上显示。发送端投出第一应用后，前台显示第二应用的界面。这种投屏技术，可以理解为，接收端显示屏作为发送端显示屏的扩展屏。
在一些实施例中，发送端向接收端投屏(包括镜像投屏或应用投屏)的过程中，接收端可能会发生屏幕旋转(比如，从横屏切换到竖屏或从竖屏切换到横屏)。当接收端屏幕旋转时，接收端上由发送端投来的界面(简称投屏界面)的尺寸会被调整以适配接收端的屏幕旋转。
为了方便理解，下文以发送端是笔记本电脑，接收端是平板电脑为例进行说明。
示例性的，如图4中的(a)，笔记本电脑上显示浏览器应用的界面401(以界面401是华为官网的一个界面为例)。界面401中包括各种显示信息，比如文字(如，HUAWEI P50等)和图片(如，手机图片)。一般，网页所包含的显示信息比较多，受限于笔记本电脑的显示屏尺寸，无法同时将网页的所有显示信息全部在显示屏上显示完，所以通常笔记本电脑会显示用于查看网页的更多信息的按键。比如，图4中的(a)中，在界面401的右侧显示滑动块402。当笔记本电脑检测到针对滑动块402的下滑操作时，显示如图4中的(b)所示的界面403。界面403可以理解为网页(如，华为官网)产生的位于界面401的下一界面。因此，用户使用笔记本电脑浏览网页时，可以通过滑动块402查看网页的更多信息。
如图5A中的(a)，假设笔记本电脑在显示界面401时，检测到向平板电脑镜像投屏的操作(将在后文介绍)时，响应于该操作，笔记本电脑向平板电脑(假设当前处于横屏状态)发送界面401的显示信息，平板电脑显示界面401，如图5A中的(b)。当平板电脑从横屏切换到竖屏时，其显示屏上的投屏界面(即界面401)的尺寸被调整。比如，如图5A中的(c)，平板电脑从横屏切换到竖屏，平板电脑上界面401被缩小。这样，平板电脑上出现黑屏区域。这种方式会导致平板电脑显示资源的浪费，而且投屏界面被缩小用户看起来比较费劲，影响用户体验。另一种方式为，平板电脑从横屏切换到竖屏时，平板电脑上投屏界面被拉伸(或称为放大)到能够占满平板电脑的显示屏，如图5A中的(d)。这种方式，虽然没有造成显示资源浪费，但是却出现了投屏界面被拉伸而变形的情况，影响用户体验。因此，目前的镜像投屏技术中，发送端向接收端投屏过程中，如果接收端屏幕旋转(如，从横屏切换到竖屏)，要么出现显示资源浪费的问题，要么出现画面被拉伸而变形的问题，体验差。
图5A是以镜像投屏为例，在应用投屏中同样也存在类似的问题。
如图5B中的(a)，笔记本电脑显示界面401。当笔记本电脑检测到向平板电脑应用投屏的操作(将在后文介绍)时，向平板电脑(假设处于横屏状态)发送界面401的显示信息，平板电脑显示界面401，如图5B中的(b)。笔记本电脑向平板电脑投屏后显示主界面，如图5B中的(c)。平板电脑从横屏切换到竖屏时，其显示屏上投屏界面的尺寸被调整。比如，如图5B中的(d)，平板电脑从横屏切换到竖屏，平板电脑上投屏来的界面401缩小。这样，平板电脑上出现黑屏区域，造成显示资源的浪费而且投屏界面被缩小用户看起来比较费劲。另一种方式为，平板电脑从横屏切换到竖屏时，平板电脑上投屏界面被拉伸 (或放大)到能够占满平板电脑的显示屏，如图5B中的(e)。这种方式投屏界面变形，影响用户体验。因此，目前的应用投屏技术中，也存在同样的问题，即发送端向接收端投屏过程中，如果接收端屏幕旋转(如，从横屏切换到竖屏)，要么出现黑屏区域，要么出现画面变形。
无论是应用投屏还是镜像投屏，出现上述问题的原因在于：发送端向接收端投屏时，仅仅是将要投屏到接收端的界面作为一张图像发送给接收端进行显示。当接收端屏幕旋转时，图像被缩小或放大。当图像缩小时会出现黑屏区域，当图像放大时会变形。
为了提升投屏体验，本申请实施例提供一种显示方法。该显示方法适应于应用投屏场景。应用投屏请参见前文介绍。具体地，第一电子设备向第二电子设备应用投屏过程中，若第二电子设备发生屏幕旋转，第一电子设备响应于第二电子设备的屏幕旋转，对要投屏到第二电子设备的界面(简称投屏界面)作调整。这种调整不是将投屏界面作为一张图片进行简单的尺寸缩放，而是对投屏界面上显示信息的布局调整，和/或，对投屏界面上显示信息进行删减或增加等。第一电子设备将调整后的投屏界面发送给第二电子设备。第二电子设备显示所述调整后的投屏界面时，不会出现画面变形，也不会出现黑屏区域，投屏体验较好。
下面介绍本申请的应用场景。
考虑到发送端可能是横屏或竖屏，接收端也可能是横屏或竖屏，所以，存在多种情况。1、发送端是横屏、接收端是横屏。2、发送端是横屏、接收端是竖屏。3、发送端是竖屏、接收端是竖屏。4、发送端是竖屏、接收端是横屏。因此，下文介绍四种应用场景，分别对应上面的四种情况。
第一种应用场景
该应用场景以笔记本电脑(处于横屏状态)向当前正处于横屏状态的平板电脑应用投屏为例。对应前面的情况1，发送端是横屏、接收端是横屏。
如图6A中的(a)，笔记本电脑显示界面401。此时，若笔记本电脑检测到向平板电脑应用投屏的操作(将在后文介绍)，响应于该操作，向平板电脑发送界面401的显示信息，平板电脑上显示界面401，如图6A中的(b)。笔记本电脑投出界面401之后显示主界面，如图6A中的(c)。
需要说明的是，笔记本电脑向平板电脑发送界面401的显示信息之前，会判断平板电脑当前屏幕显示方向是横屏还是竖屏，根据平板电脑的屏幕显示方向决定是否需要对即将要投屏到平板电脑的界面(即界面401)作调整。比如，确定平板电脑当前屏幕显示方向是横屏时，不需要对界面401作调整，因为界面401本身是适合横屏显示的(因为笔记本电脑是横屏显示界面401的)，所以，笔记本电脑直接将界面401的显示信息发送给平板电脑。值得说明的是，目前的应用投屏技术中，发送端响应于应用投屏操作，直接将发送端前台显示界面发送给接收端进行显示，并不会根据接收端当前屏幕显示方向判断是否需要对即将要投屏到接收端的界面作调整，所以目前的应用投屏技术中，发送端响应于应用投屏操作，投屏到接收端的界面不一定适配接收端当前屏幕显示方向。本申请实施例中，发送端向接收端投屏之前，可以根据接收端的屏幕显示方向判断是否需要对即将要投屏到平板电脑的界面作调整，所以投屏到接收端的界面一定适配接收端当前屏幕显示方向。
继续参见图6A中的(b)，平板电脑显示投屏来的界面401的过程中，可能会发生屏 幕旋转，如，从横屏切换到竖屏。
一种方式为，平板电脑从横屏切换到竖屏时，平板电脑上投屏界面上的显示信息增多。如图6A中的(b)和(d)，平板电脑从横屏切换到竖屏时，投屏界面由界面401变为界面501。界面501比界面401所包含的显示信息多。其中，增加的显示信息可以是界面401的上一界面、下一个界面、默认界面(比如，所述网页的主界面)或用户指定界面的显示信息。示例性的，请结合前文中的图4，界面501比界面401多出的显示信息(即虚线区域的显示信息)是界面401的下一界面403(见图4)中的显示信息。通过这种方式，当平板电脑从横屏切换到竖屏时，投屏界面上显示信息增多，不浪费显示资源，而且，用户可以获取更多的投屏信息，体验较好。
另一种方式为，平板电脑从横屏切换到竖屏时，投屏界面上显示信息不增多，而是布局方式调整。如图6A中的(b)和(e)，平板电脑从横屏切到竖屏时，平板电脑上的投屏界面从界面401变为界面502。界面502与界面401的显示信息布局方式不同。比如，界面401中文字(比如HUAWEI P50等)在左侧，图片(如，手机图片)在右侧，而界面502中文字在上侧，图片在下侧。这种方式不会对投屏界面进行尺寸缩放，所以不会出现黑屏区域而且也不会出现画面变形。
第二种应用场景
第二种应用场景以笔记本电脑(处于横屏状态)向当前正处于竖屏状态的平板电脑投屏为例。对应前面的情况2，发送端是横屏、接收端是竖屏。
如图6B中的(a)，笔记本电脑显示界面401。此时，若笔记本电脑检测到向平板电脑应用投屏的操作(将在后文介绍)，响应于该操作，向平板电脑发送界面501的显示信息，平板电脑上显示界面501，如图6B中的(b)。笔记本电脑投屏之后显示主界面，如图6B中的(c)。其中，界面501比界面401的显示信息多。比如，多出来的显示信息(即虚线区域的显示信息)可以是界面401的下一个界面(图4中界面403)中的显示信息。
请对比图6A和图6B理解，图6A中笔记本电脑向当前处于横屏的平板电脑投屏时，发送的是界面401的显示信息，图6B中笔记本电脑向当前处于竖屏的平板电脑投屏时，发送的是界面501的显示信息。这是因为，图6A中笔记本电脑发送界面401的显示信息之前，确定出平板电脑当前是横屏，而界面401是适合横屏显示的，所以直接向平板电脑发送界面401的显示信息。然而，图6B中，笔记本电脑向平板电脑发送界面501的显示信息之前，确定平板电脑当前是竖屏的，所以需要对界面401作调整，因为界面401适合横屏显示不适合竖屏显示，所以，笔记本电脑将界面401调整为界面501，将界面501发送给平板电脑。由此可知，本申请实施例中，发送端向接收端投屏之前，可以判断接收端是横屏还是竖屏，如果接收端与发送端的屏幕显示方向一致(比如，都是横屏)，发送端直接将前台显示界面的显示信息发送给接收端即可，无需对前台显示界面作调整。如果接收端与发送端屏幕显示方向不一致，比如，发送端是横屏，接收端是竖屏，发送端需要将前台显示界面作调整，将调整后的界面发送给接收端显示。因此，本申请实施例中，发送端根据接收端的屏幕显示方向对即将要投屏到接收端的界面作调整，使得调整后的界面被投屏到接收端时能够适配接收端的屏幕显示方向。
继续参见图6B中的(b)，平板电脑显示投屏来的界面501时，可能会发生屏幕旋转，如，从竖屏切换到横屏。
一种方式为，平板电脑从竖屏切换到横屏时，平板电脑上投屏界面的显示信息减少。如图6B中的(b)和(d)，平板电脑从竖屏切换到横屏时，平板电脑上投屏界面由界面501变为界面401。其中，界面401比界面501的显示信息少。其中，减少的显示信息为界面501中虚线区域内的显示信息。
另一种方式为，平板电脑从竖屏切换到横屏时，投屏界面上显示信息不减少，而且布局方式调整。比如，如图6B中的(b)和(e)，平板电脑从竖屏切换到横屏，平板电脑上投屏界面由界面501变为界面505。界面505与界面501的显示信息布局方式不同。比如，界面501中，虚线区域的显示信息在显示屏下侧，而界面505中，虚线区域的显示信息在显示屏右侧。
第三种应用场景
该应用场景对应前面的情况3，发送端是竖屏、接收端是竖屏。可以理解的是，前面的例子都是发送端是笔记本电脑为例，一般笔记本电脑都是横屏无法竖屏显示，所以该应用场景以发送端是手机为例，如处于竖屏状态的手机向当前正处于竖屏状态的平板电脑为例。
如图7A中的(a)，手机处于竖屏状态并且显示界面701。界面701比如是手机上视频播放类应用的界面。手机检测到向平板电脑应用投屏的操作(将在后文介绍)，响应于该操作，将界面701的显示信息发送给平板电脑，平板电脑显示界面701，如图7A中的(b)。手机在投出界面701之后显示桌面，如图7A中的(c)。需要说明的是，手机向平板电脑发送界面701的显示信息之前，会判断平板电脑当前屏幕显示方向是横屏还是竖屏，根据平板电脑当前屏幕显示方向决定是否需要对即将要投屏到平板电脑的界面(即界面701)作调整。比如，当确定平板电脑是竖屏时，不需要对界面701作调整，因为界面701本身就是适合竖屏显示的(因为手机竖屏显示界面701)，所以，手机直接将界面701的显示信息发送给平板电脑。
继续如图7A中的(b)，平板电脑显示投屏来的界面701时，可能会发生屏幕旋转，如，从竖屏切换到横屏。
一种方式为，平板电脑从竖屏切换到横屏时，投屏界面的显示信息减少。如图7A中的(b)和(d)，平板电脑从竖屏切换到横屏时，平板电脑上的投屏界面由界面701变为界面702。界面702比界面701的显示信息少。其中，减少的显示信息为界面701中虚线区域内的显示信息。
另一种方式为，平板电脑从竖屏切换到横屏时，投屏界面的显示信息不减少，但是布局方式调整。比如，如图7A中的(b)和(e)，平板电脑从竖屏切换到横屏时，平板电脑上的投屏界面由界面701变为界面703。界面703与界面701的显示信息布局方式不同。比如，界面701中虚线区域内的显示信息(媒体标题、选集按键等)在下侧。界面703中所述虚线区域内的显示信息在右侧。
第四种应用场景
该应用场景以处于竖屏状态的手机向处于横屏状态的平板电脑投屏为例。对应前面的情况4，发送端是竖屏、接收端是横屏。
[根据细则91更正 30.09.2022]　
如图7B中的(a)，手机处于竖屏状态并且显示界面701。手机检测到向平板电脑应用 投屏的操作，响应于该操作，将界面702的显示信息发送给平板电脑。如图7B中的(b)，平板电脑显示界面702。手机在投出界面702之后显示桌面，如图7B中的(c)。其中，界面702比界面701的显示信息少。比如，少的显示信息是界面701中虚线区域内的显示信息(媒体标题、选集按键等)。需要说明的是，手机向平板电脑发送界面702的显示信息之前，确定平板电脑当前屏幕显示方向是横屏，所以需要对界面701作调整，因为界面701不适合横屏显示，所以，将界面701调整为界面702，将界面702发送给平板电脑。如图7B中的(b)和(d)，平板电脑从横屏切换到竖屏时，平板电脑上投屏界面从界面702变为界面701，显示信息增多。

下面结合附图介绍本申请实施例提供的技术方案。
实施例一
本实施例一的目的在于介绍前面的四种应用场景的实现原理，考虑到前面的四种应用场景的实现原理相同，为了节省篇幅，本文不对每种应用场景的实现原理一一介绍。主要介绍第一种应用场景和第二种应用场景的实现原理。第三种应用场景和第四种应用场景的实现原理可以参考第一种应用场景和第二种应用场景的实现原理。
示例性的，如图9A中的(a)，笔记本电脑显示第一应用的第一界面。第一界面包括显示信息A1和显示信息A2。第一应用可以是任何应用，不作限定。比如，第一应用是浏览器应用，第一界面可以是前文中第一种应用场景(即图6A)中浏览器应用的界面401，那么显示信息A1包括文字信息(如，HUAWEI等)，显示信息A2包括手机图片，且显示 信息A1和显示信息A2在水平方向平铺显示，比如显示信息A1位于显示信息A2左侧。如图9A中的(b)，平板电脑处于横屏且显示桌面。笔记本电脑响应于与平板电脑连接的操作，与平板电脑建立连接。所述连接可以是有线或无线连接。笔记本电脑可以识别平板电脑当前屏幕显示方向是横屏还是竖屏。示例性的，平板电脑与笔记本电脑连接之后，可以主动地向笔记本电脑汇报其当前屏幕显示方向；或者，笔记本电脑向平板电脑发送请求，用于请求平板电脑的当前屏幕显示方向，平板电脑响应于该请求返回当前屏幕显示方向。
当笔记本电脑检测到向平板电脑应用投屏的操作(如，在第一界面内长按且拖动的操作)时，响应于该操作，第一应用的第一界面移动出笔记本电脑显示屏，如图9A中的(c)，同时，第一应用的第一界面进入平板电脑显示屏，如图9A中的(d)。当检测到所述长按且拖拽操作结束时，第一应用的第一界面被转移到平板电脑上显示，如图9A中的(f)。笔记本电脑上显示第二应用的界面，如图9A中的(e)。需要说明的是，笔记本电脑在显示第一界面时响应于投屏操作向平板电脑发送的是第一界面，是因为在此之前笔记本电脑确定平板电脑处于横屏状态，而第一界面是适合横屏显示的，所以发送第一界面到平板电脑。图9A中，以应用投屏操作是在第一界面内长按且拖拽的操作为例，可以理解的是，应用投屏操作还可以是其它类型的操作，本申请不一一举例。
继续参见图9A中的(f)，平板电脑显示投屏来的第一界面时，可能会发生屏幕旋转，比如，从横屏切换到竖屏。当平板电脑从横屏切换到竖屏时，有两种显示方式。
第一种方式
如图9A中的(g)，当平板电脑从横屏切换到竖屏时，平板电脑上的投屏界面从第一应用的第一界面变为第一应用的第三界面。第三界面比第一界面的显示信息多。第三界面中包括显示信息A1和A2，还包括显示信息B。其中，显示信息A1和A2是第一界面中的显示信息，所以可以理解为，第三界面包括第一界面的全部显示信息还包括其它界面的显示信息，所述其它界面可以是第一界面的上一界面或下一界面或默认界面或用户指定界面中的显示信息。比如，以前文的图6A为例的话，第一界面是界面401，第三界面是界面501.，显示信息B可以是界面501比界面401多出来的显示信息，即界面501中虚线区域内的显示信息，即第一界面(界面401)的下一界面(图4中界面403)的显示信息。
第二种方式
如图9A中的(h)，当平板电脑从横屏切换到竖屏时，平板电脑上的投屏界面从第一应用的第一界面变为第一应用的第四界面。第四界面与第一界面的显示信息布局不同。第一界面中显示信息A1和显示信息A2在水平方向上平铺显示，第四界面中显示信息A1和显示信息A2在竖直方向上平铺显示，比如显示信息A1位于显示信息A2的上侧。比如，以前面的图6A为例的话，第一界面是界面401、第四界面是界面502，界面502与界面401的显示信息布局不同。
图9B为图9A对应的后台处理流程。
如图9B中的(a)，主设备(即图9A中的笔记本电脑包)括本地显示屏。本地显示屏是横屏。本地显示屏显示第一应用的第一界面，对应图9A中的(a)。如图9B中的(b)，笔记本电脑创建第一虚拟显示器(virtual display，VD)。第一VD用于将第一VD中的显示信息投屏到目标设备(即图9A中的平板电脑)上显示，即目标设备上显示的投屏信息是第一VD中的显示信息。第一VD的显示参数与目标设备(即，平板电脑)显示参数匹 配。比如，第一VD的屏幕显示方向与目标设备当前屏幕显示方向一致，和/或，第一VD的长宽比等于目标设备的长宽比。假设主设备确定目标设备当前屏幕显示方向为横屏时，则第一VD为横屏，此时，本地显示屏和第一VD都是横屏，如图9B中的(b)。可以理解的是，主设备创建第一VD可以包括：在检测到与目标设备连接时创建，或者，在检测到向目标设备应用投屏操作时创建；或者，第一VD可以是默认存在的(比如，出厂之后就默认设置好的)，本申请实施例对此不作限定。
主设备响应于向目标设备的应用投屏操作，将第一应用从本地显示屏转移到第一VD中运行。可以理解为，第一应用原本在本地显示屏上显示，被转移到第一VD上显示。如图9B中的(b)，第一应用原本在本地显示屏上显示的是第一界面，当转移到第一VD时，仍然显示第一界面。这是因为第一VD和本地显示屏都是横屏，而第一界面本身就已适配横屏显示，所以第一应用转移到第一VD时，不需要调整第一界面。然后，第一VD将第一界面发送给目标设备，目标设备显示第一界面。继续如图9B中的(b)，第一应用从本地显示屏转移到第一VD之后，本地显示屏上显示第二应用的界面。
当第一VD中的第一界面投屏到目标设备之后，目标设备可能发生屏幕旋转，如从横屏切换到竖屏。如图9B中的(a)，当目标设备从横屏切换为竖屏时，向主设备发送屏幕旋转指令，该指令中指示目标设备切换为竖屏。
第一种方式
如图9B中的(c)，主设备基于所述指令调整第一VD的屏幕显示方向为竖屏。第一VD被调整为竖屏显示时，第一应用会调整第一界面为第三界面。比如，第三界面比第一界面的显示信息增多，即增加显示信息B，以适配第一VD的竖屏显示。第一VD将第三界面发送给目标设备，目标设备显示第三界面。
第二种方式
如图9B中的(d)，主设备基于所述指令调整第一VD的屏幕显示方向为竖屏。第一VD被调整为竖屏显示时，第一应用会调整第一界面为第四界面。比如，第四界面与第一界面的显示信息布局不同。如，第一界面中显示信息A1和A2水平方向上平铺显示，第四界面中显示信息A1与显示信息A2在竖直方向平铺显示，以适配第一VD的竖屏显示。第一VD将第四界面发送给目标设备。
需要说明的是，图9A至图9B可以适用于前面的第一种应用场景，对应情况1，即发送端是横屏、接收端是横屏。可以理解的是，对于第三种应用场景(对应情况3，即发送端是竖屏、接收端是竖屏)，也是同样的原理，所以，为了节省篇幅，不重复赘述。
示例性的，如图10A中的(a)，笔记本电脑显示第一应用的第一界面。第一界面中包括显示信息A。第一应用可以是任何应用，不作限定。比如，第一应用是浏览器应用，第一界面可以是前文中第二种应用场景即图6B中浏览器应用的界面401，那么显示信息A包括界面401中的文字信息(如，HUAWEI等)以及手机图片等。如图10A中的(b)，平板电脑处于竖屏状态且显示桌面。笔记本电脑与平板电脑连接。笔记本电脑确定平板电脑当前屏幕显示方向为竖屏。当笔记本电脑检测到向平板电脑的应用投屏操作(如，在第一界面内长按且拖拽操作)时，响应于该操作，第一应用的界面被移动出笔记本电脑显示屏，如图10A中的(c)，同时，第一应用的界面移入平板电脑显示屏，如图10A中的(d)。当检测到所述长按且拖拽操作结束时，笔记本电脑上显示第二应用的界面，如图10A中的(e)， 平板电脑上显示第一应用的第二界面，如图10A中的(f)。第二界面与第一界面不同。第二界面比第一界面的显示信息多，如，第二界面比第一界面多出显示信息B。因为显示信息A是第一界面的，所以可以理解为第二界面包括第一界面的全部显示信息，还包括其它界面的显示信息，所述其它界面可以是第一界面的下一界面或上一界面或第一应用的默认界面或用户指定界面。比如，以前文图6B为例的话，第一界面是界面401，第二界面是界面501。界面501比界面401多出了虚线区域的显示信息，这部分显示信息是界面401的下一界面(图4中的界面403)的显示信息。需要说明的是，图10A中，笔记本电脑响应于向平板电脑的投屏操作，向平板电脑发送的是第二界面的显示信息，这是因为，笔记本电脑确定平板电脑当前处于竖屏，而第一界面不适合竖屏显示，所以笔记本电脑将第二界面发送给平板电脑，以适配平板电脑的竖屏显示。
继续参见图10A中的(f)，平板电脑显示投屏来的第二界面时，可能会发生屏幕旋转，比如从竖屏切换到横屏。
第一种方式
如图10A中的(f)和(g)，当平板电脑从竖屏切换到横屏时，平板电脑上投屏界面从第一应用的第二界面变为第一应用的第三界面。第三界面上包括显示信息A，比第二界面显示信息减少。比如，以前文图6B为例的话，第二界面是界面501，第三界面是界面401，界面401比界面501的显示信息少。
第二种方式
如图10A中的(f)和(h)，当平板电脑从竖屏切换到横屏时，平板电脑上投屏界面从第一应用的第二界面变为第一应用的第四界面。第四界面与第二界面的显示信息布局方式不同。第二界面中显示信息A和B是竖直方向上平铺显示，第四界面中显示信息A和B是在水平方向上平铺显示，比如，显示信息A在左侧，显示信息B在右侧。比如，以前文图6B为例的话，第四界面是界面505，第二界面是界面501，界面505与界面501的显示信息布局不同。
图10B为图10A对应的后台处理过程。
如图10B中的(a)，主设备(即图10A中的笔记本电脑)包括本地显示屏。本地显示屏是横屏。本地显示屏显示第一应用的第一界面。第一界面中包括显示信息A，对应图10A中的(a)。笔记本电脑创建第一VD，如图10B中的(b)。第一VD用于将第一VD中的显示信息投屏到目标设备(即图10A中的平板电脑)上显示。第一VD的显示参数与目标设备(即，平板电脑)显示参数匹配。比如，第一VD的屏幕显示方向与目标设备当前屏幕显示方向一致，和/或，第一VD的长宽比等于目标设备的长宽比。假设主设备确定目标设备当前屏幕显示方向为竖屏时，则第一VD为竖屏。此时，本地显示屏是横屏、第一VD是竖屏，如图10B中的(b)。
主设备响应于向目标设备的应用投屏操作，将第一应用转移到第一VD中运行。可以理解为，第一应用原本在本地显示屏上显示，被转移到第一VD上显示。
如图10B中的(b)，第一应用原本在本地显示屏上显示的是第一界面，第一界面中包括显示信息A，以适配本地显示屏的横屏状态。当第一应用被转移到第一VD时，由于第一VD是竖屏，所以第一应用在第一VD中显示第二界面，第二界面中包括显示信息A和显示信息B，且显示信息A和显示信息B在竖直方向平铺，以适配第一VD的竖屏状态。换言之，本地显示屏是横屏，第一VD是竖屏，第一应用原本在本地显示屏上显示的第一 界面适配横屏显示而不适配竖屏显示，所以第一应用转移到第一VD时调整第一界面为第二界面，第二界面适配第一VD的竖屏显示。第一VD将第二界面发送给目标设备。第一应用从本地显示屏转移到第一VD之后，本地显示屏上显示第二应用的界面。
当第一VD中的第二界面投屏到目标设备之后，目标设备可能发生屏幕旋转，如从竖屏切换到横屏。如图10B中的(b)，当目标设备从竖屏切换到横屏时，向主设备发送屏幕旋转指令，该指令中指示目标设备切换为横屏。
第一种方式
如图10B中的(c)，主设备基于所述指令调整第一VD的屏幕显示方向为横屏。第一VD被调整为横屏显示时，第一应用会调整第二界面为第三界面，以适配第一VD的横屏显示。第三界面比第二界面的显示信息少。第一VD将第三界面发送给目标设备。
第二种方式
[根据细则91更正 30.09.2022]　
如图10B中的(d)，主设备基于所述指令调整第一VD的屏幕显示方向为横屏。第一VD被调整为横屏显示时，第一应用会调整第二界面为第四界面。第四界面与第二界面的显示信息布局不同，第二界面中显示信息A和B是竖直方向上平铺显示，第四界面中显示信息A和B是在水平方向上平铺显示，以适配第一VD的横屏显示。第一VD将第四界面发送给目标设备。
图10A至图10B可以适用于前面的第二种应用场景，对应情况2，即发送端是横屏、接收端是竖屏。可以理解的是，对于第四种应用场景(对应情况4，即发送端是竖屏、接收端是横屏)，也是同样的原理，所以，为了节省篇幅，不重复赘述。
请参见图11，为本申请实施例提供的显示方法的一种流程示意图。如图11所示，所述流程包括：
S1101，主设备与目标设备连接。
主设备与目标设备的连接方式有多种，包括有线连接、无线连接，比如蓝牙、无线保真(wireless fidelity，WIFI)、近场通讯(near field communication，NFC)等连接方式。
S1102，目标设备向主设备发送屏幕显示方向。
在一些实施例中，目标设备可以主动向主设备发送屏幕显示方向。比如，目标设备在检测到与主设备连接之后，自动向主设备发送屏幕显示方向。可以理解的是，在此之前，目标设备可以检测本机的屏幕显示方向，具体的检测方式有多种，比如通过运动传感器(比如，陀螺仪等)采集到传感器数据来检测屏幕显示方向，本申请实施例不作限定。
在另一些实施例中，目标设备在接收到主设备发送的用于请求屏幕显示方向的请求之后向主设备发送屏幕显示方向。即，目标设备检测到与主设备连接之后，暂时不向主设备发送其屏幕显示方向，在接收到来自主设备的请求之后向主设备发送屏幕显示方向。
示例性的，目标设备向主设备发送屏幕显示方向，可以包括：目标设备向主设备发送一指令，该指令中携带一个指示信息。所述指示信息可以占1比特，比如当指示信息是1时，代表屏幕显示方向为横屏，当该指示信息是0时，代表屏幕显示方向为竖屏。
示例性的，目标设备可以通过各种方式向主设备发送屏幕显示方向，比如，如果主设备与目标设备是有线连接，则通过有线方式发送，如果主设备与目标设备是无线连接，则通过无线发送，比如，蓝牙、WIFI、NFC等无线发送。
可选的，S1102可以不执行，所以图中使用虚线表示。
S1103，主设备显示第一应用的第一界面。
在一些实施例中，S1103可以执行或不执行，所以图中使用虚线表示。比如，主设备当前显示的是主界面，主设备可以响应于应用投屏操作将第一应用的第一界面投屏到目标设备。也就是说，主设备投屏出的界面可以是主设备当前显示界面，也可以不是主设备当前显示界面。
需要说明的是，S1101至S1103的执行顺序本申请不作限定。
S1104，主设备接收到向目标设备投屏的操作。

S1105，主设备判断主设备与目标设备的屏幕显示方向是否一致，如果一致，执行S1106和S1107，如果不一致，执行S1108和S1109。
S1106，主设备将第一应用的第一界面发送给目标设备。
S1107，目标设备显示第一界面。
因为第一界面是适配主设备的屏幕显示方向的，如果主设备与目标设备屏幕显示方向一致时，那么第一界面也是适配目标设备的屏幕显示方向的，所以主设备将第一界面发送给目标设备，无需对第一界面作调整。示例性的，如图9A，笔记本电脑和平板电脑都是横屏(屏幕显示方向一致)，笔记本电脑显示第一界面时响应于投屏操作，向平板电脑投屏第一界面。
S1108，主设备将第一应用的第二界面发送给目标设备。
S1109，目标设备显示第二界面。
因为第一界面是适配主设备的屏幕显示方向的，而主设备与目标设备屏幕显示方向不一致，所以第一界面不适配目标设备的屏幕显示方向，所以主设备可以将第一界面调整为第二界面，将第二界面发送给目标设备。示例性的，如图10A，笔记本电脑是横屏，平板电脑是竖屏(屏幕显示方向不一致)，笔记本电脑显示第一界面时响应于投屏操作，向平板电脑投屏第二界面。
S1110，主设备显示第二应用的界面。
也就是说，主设备向目标设备投出第一应用之后，主设备前台显示第二应用的界面，即第一应用切换到主设备的后台运行。
在一些实施例中，S1110是可选步骤，可以执行或不执行，所以图中S1110使用虚线表示。比如，主设备投出第一应用的第一界面之后，仍然可以显示第一应用的第一界面，当检测到用于将第一应用切换到后台的操作时，显示第二应用的界面。
S1111，目标设备检测到屏幕旋转操作。所述屏幕旋转操作用于将目标设备从横屏切换到竖屏或者从竖屏切换到横屏。
S1112，目标设备向主设备发送屏幕旋转指令。
示例性的，所述屏幕旋转指令用于指示目标设备从横屏切换到竖屏或者从竖屏切换到横屏。在一些实施例中，目标设备向主设备发送屏幕旋转指令可以包括：目标设备向主设备发送一指令，该指令中携带一个指示信息。所述指示信息可以占1比特。比如，目标设备从竖屏切换到横屏时，所述指示信息为1，代表当前屏幕显示方向为横屏(即从竖屏切换到横屏)。目标设备从横屏切换到竖屏时，所述指示信息为0，代表当前屏幕显示方向为竖屏(即从横屏切换到竖屏)。
示例性的，目标设备可以通过各种方式向主设备发送屏幕旋转指令，比如，如果主设备与目标设备是有线连接，则通过有线方式发送，如果主设备与目标设备是无线连接，则通过无线发送，比如，蓝牙、WIFI、NFC等无线发送。
S1113，主设备基于屏幕旋转指令调整第一应用的界面为第三界面或者第四界面。
可以理解的是，如图前面执行的是S1106和S1107，即第一应用当前显示的是第一界面，则将第一界面调整为第三界面或第四界面，请参见前文图9A。如果前面执行的是S1108和S1109，即第一应用当前显示的是第二界面，则将第二界面调整为第三界面或第四界面，请参见前文图10A。
S1114，主设备将第三界面或第四界面的显示信息发送给目标设备。
S1115，目标设备显示第三界面或第四界面。
示例性的，如图9A，目标设备从横屏切换到竖屏时，目标设备上的投屏界面从第一界面变为第三界面或第四界面，以适配目标设备的竖屏显示。或者，如图10A，目标设备从竖屏切换到横屏时，目标设备上的投屏界面从第二界面变为第三界面或第四界面，以适配目标设备的横屏显示。
需要说明的是，图11中可选步骤均使用虚线表示，当可选步骤全部不执行时，本申请提供的显示方法包括：主设备检测到投屏操作(S1104)，响应于该操作将主设备中第一应用的第一界面的显示信息发送给目标设备(S1106)，目标设备显示第一界面(S1107)。目标设备检测到屏幕旋转操作(S1111)。目标设备向主设备发送屏幕旋转指令(S1112)。主设备响应于该指令调整第一应用的界面为第三界面或第四界面(S1113)。主设备将第三界面或第四界面的显示信息发送给目标设备(S1114)，目标设备显示第三界面或第四界面(S1115)。
请参见图12，为本申请实施例提供的显示方法的另一种流程示意图。图12所示流程也可以理解为图11所示的流程的细化。如图12，所述流程包括：
S1201，主设备与目标设备连接。
S1202，目标设备向主设备发送屏幕显示方向。
S1203，主设备的本地显示屏显示第一应用的第一界面。
S1204，主设备接收到向目标设备投屏的操作。
前面的S1201至S1204的实现原理请参见图11中S1101至S1104的实现原理，不重复赘述。
S1205，主设备创建第一VD，第一VD的屏幕显示方向与目标设备的屏幕显示方向一致。
示例性的，如图9B中的(b)，目标设备是横屏，则主设备创建的第一VD是横屏。或者，如图10B中的(b)，目标设备是竖屏，则主设备创建的第一VD是竖屏。
S1206，主设备判断本地显示屏与第一VD的屏幕显示方向是否一致。如果一致，执行S1207至S1209，如果不一致，执行S1210至S1212。
S1207，第一应用从本地显示屏转移到第一VD，第一应用在第一VD中显示第一界面。
S1208，第一VD将第一应用的第一界面发送给目标设备。
S1209，目标设备显示第一界面。
因为第一界面是适配本地显示屏的屏幕显示方向的，如果本地显示屏与第一VD的屏 幕显示方向一致，那么第一界面也是适配第一VD的屏幕显示方向的，所以第一应用转移到第一VD时仍然显示第一界面，无需对第一界面作调整。示例性的，如图9B中的(b)，第一应用从本地显示屏转移到第一VD时，显示第一界面。第一VD将第一界面投屏到目标设备显示。因为第一VD的屏幕显示方向与目标设备一致，所以第一VD投出的第一界面适配目标设备的屏幕显示方向。
S1210，第一应用从本地显示屏转移到第一VD，第一应用在第一VD中显示第二界面。
S1211，第一VD将第一应用的第二界面发送给目标设备。
S1212，目标设备显示第二界面。
因为第一界面是适配本地显示屏的屏幕显示方向的，如果本地显示屏与第一VD的屏幕显示方向不一致，那么第一界面不适配第一VD的屏幕显示方向，所以第一应用转移到第一VD时显示第二界面以适配第一VD的屏幕显示方向。示例性的，如图10B中的(b)，第一应用从本地显示屏转移到第一VD时，显示第二界面。第一VD将第二界面投屏到目标设备显示。因为第一VD的屏幕显示方向与目标设备一致，所以第一VD投出的第二界面适配目标设备的屏幕显示方向。
S1213，主设备本地显示屏显示第二应用的界面。
在一些实施例中，S1213是可选步骤，可以执行或不执行，所以图中S1213使用虚线表示。比如，主设备投出第一应用的第一界面之后，本地显示屏仍然可以显示第一应用的第一界面，当检测到用于将第一应用切换到后台的操作时，本地显示屏显示第二应用的界面。
S1214，目标设备检测到屏幕旋转。

实施例二
本实施例二以镜像投屏为例。下面介绍镜像投屏的应用场景。
考虑到发送端可能是横屏或竖屏，接收端也可能是横屏或竖屏，所以，镜像投屏存在多种情况。1、发送端是横屏、接收端是横屏。2、发送端是横屏、接收端是竖屏。3、发送端是竖屏、接收端是竖屏。4、发送端是竖屏、接收端是横屏。因此，下文包括四种应用场景，分别对应上面的四种情况。
第一种应用场景
该应用场景对应前面的情况1，发送端是横屏、接收端是横屏。
如图13A中的(a)，手机当前处于横屏状态且显示界面1701。界面1701比如是视频播放应用的界面。此时，若手机检测到镜像投屏操作，向平板电脑发送界面1701的显示信息，平板电脑显示界面1701，如图13A中的(b)。需要说明的是，手机向平板电脑发送界面1701的显示信息之前，会判断平板电脑的屏幕显示方向是横屏还是竖屏，根据平板电脑的屏幕显示方向决定是否需要对即将要投屏到平板电脑的界面(即界面1701)作调整。当确定平板电脑是横屏时，不需要对界面1701作调整，因为界面1701本身就是适合横屏显示的(因为手机是横屏)，所以，手机直接将界面1701的显示信息发送给平板电脑。值得说明的是，目前的镜像投屏技术中，发送端响应于投屏操作，将发送端前台显示界面发送给接收端进行显示，并不会根据接收端当前屏幕显示方向判断是否需要对即将要投屏到接收端的界面作调整，所以目前的投屏技术中，发送端响应于镜像投屏操作，投屏到接收端的界面不一定适配接收端当前屏幕显示方向。
如图13A中的(c)，当平板电脑从横屏切换到竖屏时，投屏界面由界面1701变为界面1702。对应的，手机上的界面也变为界面1702，如图13A中的(d)。也就是说，虽然手机保持横屏的姿态(横屏放置的)，但是随着接收端(即平板电脑)从横屏切换到竖屏，手机上也进入竖屏模式。
第二种应用场景
该应用场景对应前面的情况2，发送端是横屏、接收端是竖屏。
如图13B中的(a)，手机当前处于横屏状态且显示界面1701。此时，若手机检测到镜像投屏操作，向平板电脑发送界面1702的显示信息，平板电脑显示界面1702，如图13B中的(b)。请结合图13A和图13B理解，图13A中，手机响应于镜像投屏操作向平板电脑发送的是界面1701的显示信息，图13B中，手机响应于镜像投屏操作，向平板电脑发送的界面1702的显示信息。这是因为，图13A中手机向平板电脑投屏之前，确定平板电脑当前屏幕显示方向是横屏，而手机当前显示界面1701适配横屏显示，所以不需要调整界面1701直接将界面1701投屏到平板电脑。然而，图13B中手机向平板电脑投屏之前，确定平板电脑当前屏幕显示方向是竖屏，而手机当前显示的界面1701不适合竖屏显示，所以手机将界面1701调整为界面1702，将界面1702投屏到平板电脑。当手机投出界面1702时，手机也显示界面1702，如图13B中的(c)。
如图13B中的(d)，当平板电脑从竖屏切换到横屏时，投屏界面由界面1702变为界面1701。对应的，手机上的界面也变为界面1701，如图13B中的(e)。也就是说，随着接收端(即平板电脑)从竖屏切换到横屏，手机也从竖屏模式切换到横屏模式。
第三种应用场景
该应用场景对应前面的情况3、发送端是竖屏、接收端是竖屏。
如图13C中的(a)，手机当前处于竖屏状态且显示界面1702。此时，若手机检测到镜像投屏操作，向平板电脑发送界面1702的显示信息，平板电脑显示界面1702，如图13C中的(b)。需要说明的是，手机向平板电脑发送界面1702的显示信息之前，确定平板电脑是竖屏，所以不需要对界面1702作调整，直接将界面1702的显示信息发送给平板电脑，因为界面1702本身就是适合竖屏显示的(因为手机是竖屏显示界面1702)。
如图13C中的(c)，当平板电脑从竖屏切换到横屏时，投屏界面由界面1702变为界面1701。对应的，手机上的界面也变为界面1701，如图13C中的(d)。也就是说，虽然手机保持竖屏的姿态，但是随着接收端(即平板电脑)从竖屏切换到横屏，手机上也进入横屏模式。
第四种应用场景
该应用场景对应前面的情况4，发送端是竖屏、接收端是横屏。
如图13D中的(a)，手机当前处于竖屏状态且显示界面1702。此时，若手机检测到镜像投屏操作，向平板电脑发送界面1701的显示信息，平板电脑显示界面1701，如图13D中的(b)。这是因为，手机向平板电脑投屏之前，确定平板电脑当前屏幕显示方向是横屏，而界面1702不适合横屏显示，所以将界面1702调整为界面1701，将界面1701发送给平板电脑。当手机投出界面1701时，手机也显示界面1701，如图13D中的(c)。
如图13D中的(d)，当平板电脑从横屏切换到竖屏时，投屏界面由界面1701变为界面1702。对应的，手机上的界面也变为界面1702，如图13D中的(e)。
下面介绍上面的四种应用场景的实现原理。需要说明的是，考虑到上面四种应用场景的实现原理相同。为了节省篇幅，主要以上面第四种应用场景为例介绍。
如图14中的(a)，手机显示第一界面。所述第一界面例如可以图13D中的界面1702，或者其它界面。所述第一界面中包括显示信息A和显示信息B。如果第一界面是界面1702，显示信息A可以是视频播放窗口，显示信息B可以是媒体标题、选集按键的信息。如图14中的(b)，平板电脑显示主界面。手机与平板电脑连接。所述连接可以是有线或无线连接。手机可以识别平板电脑当前屏幕显示方向是横屏还是竖屏。示例性的，平板电脑与手机连接之后，可以主动地向手机汇报其当前屏幕显示方向；或者，手机可以向平板电脑发送请求，用于请求平板电脑的当前屏幕显示方向，平板电脑响应于该请求返回当前屏幕显示方向。
手机检测到镜像投屏操作(如，在下滑通知栏界面或者上拉控制中心界面中点击投屏按键的操作)时，显示如图14中的(c)所示的界面，该界面中包括周围设备的标识。当检测到针对平板电脑的标识的操作时，向平板电脑发送第二界面的显示信息，平板电脑显示第二界面，如图14中的(d)。这是因为，手机确定平板电脑当前处于横屏状态，而第一界面不适合横屏显示，所述手机将第一界面调整为第二界面并将第二界面发送给平板电脑。第二界面比第一界面的显示信息少，比如第二界面只包括视频播放窗口，如图13D中的(b)。手机向平板电脑发送第二界面后，手机也显示第二界面，如图14中的(e)。也就是说，手机原本处于竖屏模式并显示第一界面，当手机需要向处于横屏状态的平板电脑投屏时，手机调整第一界面为第二界面，将第二界面投屏到平板电脑，并且手机也从竖屏模式切换到横屏模式显示第二界面。
如图14中的(f)，平板电脑从横屏切换到竖屏时，平板电脑上投屏界面从第二界面变为第一界面，即显示信息增多，而且，手机上也对应的调整为第一界面，如图14中的(g)。 因此，手机原本是横屏模式，当目标设备(即平板电脑)从横屏切换到竖屏时，手机也相应的调整为竖屏模式。
图15为图14对应的后台处理过程。
如图15中的(a)，主设备(即图14中的手机)包括本地显示屏。本地显示屏处于竖屏模式，并显示第一界面。第一界面中包括显示信息A和显示信息B。对应图14中的(a)。如图15中的(b)，主设备创建第一VD。第一VD用于将第一VD中的显示信息投屏到目标设备上。第一VD的显示参数与目标设备的显示参数匹配，比如第一VD的屏幕显示方向与目标设备的屏幕显示方向一致，和/或，第一VD的长宽比与目标设备的长宽比匹配，等等。比如目标设备是横屏，则第一VD是横屏。
在创建第一VD之后，本地显示屏的显示信息需要映射到第一VD中，使得第一VD将第一VD中的显示信息发送给目标设备。
需要说明的是，如图15中的(b)，第一VD是横屏(因为目标设备是横屏)，本地显示屏是竖屏。所以，本地显示屏向第一VD映射显示信息时，可以调整本地显示屏上的第一界面为第二界面，如图15中的(c)，第二界面适配横屏显示，比如第二界面中包括显示信息A。本地显示屏将第二界面映射到第一VD中。第一VD将第二界面投屏到目标设备。也就是说，镜像投屏中，第一VD的屏幕显示方向与目标设备的屏幕显示方向一致，当本地显示屏与第一VD的屏幕显示方向不一致时，调整本地显示屏的界面，以适配第一VD的屏幕显示方向，这样，投屏到目标设备的界面是适配目标设备的屏幕显示方向的。
主设备向目标设备投屏第二界面之后，目标设备的屏幕可能发生旋转。比如，从横屏切换到竖屏。如图15中的(c)，目标设备从横屏切换到竖屏时，向主设备发送屏幕旋转指令，用于指示目标设备切换到竖屏。
如图15中的(d)，主设备接收到目标设备的屏幕旋转指令之后，根据所述屏幕旋转指令，将第一VD从横屏切换为竖屏。随着第一VD切换到竖屏，本地显示屏也切换到竖屏模式，所以本地显示屏上的界面从第二界面切换到第三界面，并将第三界面向第一VD映射。第一VD将第三界面发送给目标设备。
请参见图16，为本申请实施例提供的显示方法的一种流程示意图。该方法适用于镜像投屏。如图16所示，所述流程包括：
S2001，主设备与目标设备连接。
S2002，目标设备向主设备发送屏幕显示方向。
S2003，主设备显示第一应用的第一界面。
S2004，主设备接收到向目标设备投屏的操作。

S2005，主设备判断主设备与目标设备的屏幕显示方向是否一致，如果一致，执行S2006至S2007，如果不一致，执行S2008和S2010。
S2006，主设备将第一应用的第一界面发送给目标设备。
S2007，目标设备显示第一界面。
因为第一界面是适配主设备的屏幕显示方向的，如果主设备与目标设备屏幕显示方向一致，那么第一界面也是适配目标设备的屏幕显示方向的，所以主设备将第一界面发送给目标设备，无需对第一界面作调整。
S2008，主设备调整本机屏幕显示方向并显示第一应用的第二界面。
S2009，主设备将第一应用的第二界面发送给目标设备。
S2010，目标设备显示第二界面。
因为第一界面是适配主设备的屏幕显示方向的，如果主设备与目标设备屏幕显示方向不一致，那么第一界面不适配目标设备的屏幕显示方向，所以主设备调整本机屏幕显示方向与目标设备一致，并将第一界面调整为第二界面，第二界面被发送给目标设备。
S2011，目标设备检测到屏幕旋转。
S2012，目标设备向主设备发送屏幕旋转指令。
示例性的，S2011至S2012的实现原理请参见图11中S1111至S1112的实现原理，不重复赘述。
