本申请实施例的界面显示方法，检测到针对第一显示屏显示的应用界面的第一触摸操作后，创建虚拟显示屏，建立所述虚拟显示屏与第二显示屏的映射关系，所述映射关系用于将所述虚拟显示屏的内容映射到所述第二显示屏；将所述应用界面所在的应用容器从所述第一显示屏移动至所述虚拟显示屏；调整所述应用容器，使得调整后的应用容器的长度小于或等于所述第二显示屏的长度，调整后的应用容器的宽度小于或等于所述第二显示屏的宽度。本申请实施例中，应用界面原本在第一显示屏显示，将应用界面所在的应用容器移动到虚拟显示屏后，可以将虚拟显示屏中的应用容器中的应用界面的内容映射到第二显示屏，从而实现将第一显示屏中显示的应用界面推送到第二显示屏中显示。由于应用容器的长度小于或等于第二显示屏的长度，应用容器的宽度或等于小于第二显示屏的宽度，应用容器中的应用界面的内容映射到第二显示屏时不会出现界面元素显示不全或者重叠的情况，可以避免应用界面从第一显示屏移动到第二显示屏中显示时出现显示异常。以下具体进行说明。
请参阅图1，图1是本申请实施例提供的一种界面显示方法的流程示意图。如图1所示，该方法可以包括如下步骤。
101，终端设备检测到针对第一显示屏显示的应用界面的第一触摸操作后，创建虚拟显示屏。
本申请实施例中，第一显示屏可以是触摸显示屏。第一触摸操作可以是滑动操作、点击操作中的至少一种。滑动操作可以包括：向上滑动、向下滑动、向左滑动、向右滑动中的任一种。点击操作可以包括：单击操作、双击操作、三击操作、四击操作中的任一种。
触摸显示屏，是指具有触摸输入能力的显示屏。
第一显示屏显示的应用界面，可以是第一显示屏当前显示的应用界面或者第一显示屏的近期任务卡片的应用界面。近期任务卡片，可以是在第一显示屏中近期打开的应用所在的卡片。例如，在手机中，可以查看近期打开的各个应用，每个应用都可以通过卡片的形式显示出来。
应用界面，可以包括一个应用的应用界面。也可以包括至少两个应用的应用界面。
可选的，所述应用界面可以包括至少一个应用的应用界面。
本申请实施例中，应用界面包括至少一个应用的应用界面时，可以将至少一个应用的应用界面(比如，分屏显示的至少两个应用的应用界面)投射到另外一个屏幕(第二显示屏)显示。可以适用于将某个应用界面显示在多个不同分辨率的物理屏幕下。
本申请实施例还可以将一个显示屏(第一显示屏)的多个应用界面组合再一起投射到另一个显示屏(第二显示屏)，或者可以将一个应用界面投射到多个不同尺寸的显示屏(第二显示屏)上。
虚拟显示屏(virtual display)，也可以称为虚拟屏或虚拟显示器。虚拟显示屏对用户来说不可见。虚拟显示屏可以通过安卓(Android)系统的原生组件进行创建。
102，终端设备建立虚拟显示屏与第二显示屏的映射关系，映射关系用于将虚拟显示屏的内容映射到第二显示屏。
第二显示屏可以是触摸显示屏，也可以是不具有触摸输入能力的显示屏。
其中，第一显示屏可以是一个显示屏。第二显示屏可以是一个显示屏，也可以是至少两个显示屏。
第一显示屏的面积与第二显示屏的面积不同，或者第一显示屏的长宽比与第二显示屏的长宽比不同。
其中，第一显示屏的面积与第二显示屏的面积不同，可以是第一显示屏的面积大于第二显示屏的面积，比如，第一显示屏可以是折叠屏的内屏，第二显示屏可以是折叠屏的外屏。还可以是第一显示屏的面积小于第二显示屏的面积，比如，第一显示屏可以是手机的显示屏，第二显示屏可以是平板电脑或电视机的显示屏。
第一显示屏和第二显示屏均为物理显示屏。比如，可以为液晶显示屏、发光二极管(light emitting diode，LED)显示屏、有机发光二极管(organic light emitting diode，OLED)显示屏中的任一种。
在一个可能的实施例中，终端设备可以包括第一显示屏和第二显示屏，终端设备可以包含多个显示屏，第一显示屏和第二显示屏是终端设备包含的多个显示屏中的任意两个。例如，第一显示屏和第二显示屏可以分别为终端设备的折叠屏中的内屏(内屏可以为主屏)和外屏(外屏可以为副屏)。一般而言，内屏的尺寸要大于外屏的尺寸，内屏的分辨率要大于外屏的分辨率。例如，内屏的分辨率可以是1960*1080，外屏的分辨率可以是640*480。这里的分辨率指的是屏幕分辨率，也可以是显示分辨率。
在一个可能的实施例中，终端设备可以包括第一显示屏，第二显示屏可以位于其他的电子设备中。比如，第一显示屏可以是平板电脑中的显示屏，第二显示屏可以是手机中的显示屏。终端设备的第一显示屏和电子设备的第二显示屏可以进行屏幕通信。可以将第一显示屏中的应用界面投屏显示到第二显示屏中。
其中，建立虚拟显示屏与第二显示屏的映射关系后，可以将虚拟显示屏的内容映射到第二显示屏。建立映射关系之后，第二显示屏显示的内容为虚拟显示屏中的内容。
可以通过桌面应用检测到针对第一显示屏显示的应用界面的第一触摸操作。
第一触摸操作，可以是针对当前的应用界面的上滑手势。也可以是针对近期任务卡片的应用界面的上滑手势。
在创建虚拟显示屏时，虚拟显示屏中没有任何的内容。在执行步骤102时，虽然建立了虚拟显示屏与第二显示屏的映射关系，由于虚拟显示屏中没有任何的内容，第二显示屏也不显示任何内容。
103，终端设备将应用界面所在的应用容器从第一显示屏移动至虚拟显示屏。
本申请实施例中，应用界面可以是某一个或至少两个应用的应用界面。应用容器可以是用来承载至少一个应用界面的容器。在安卓系统中，应用界面可以通过活动窗口(Activity)来表示。每个应用可以对应一个应用容器(Task)，一个应用容器可以承载对应的应用的至少一个活动窗口。一个应用可以对应多个活动窗口，第一显示屏当前显示的应用界面是该应用容器中层级最高(比如，位于底层)的活动窗口。
Task是一个容器，而Activity是填充这个容器的活动窗口。一般而言，第一个加入该Task的Activity则会处于该Task的最下面(层级最低)，最后加入该Task的Activity则会在最上面(层级最高)。从Task中取出Activity是从最顶端取出，也就是说最先取出的是最后添加的Activity。
在创建虚拟显示屏后，将应用界面所在的应用容器从第一显示屏移动至虚拟显示屏后，此时虚拟显示屏中只有一个应用容器，即应用界面所在的应用容器，虚拟显示屏中显示的内容为应用容器中的内容。
104，终端设备调整应用容器，使得调整后的应用容器的长度小于或等于第二显示屏的长度，调整后的应用容器的宽度小于或等于第二显示屏的宽度。
可以通过一推管理服务(OplusPuttmanagerService)来调整该应用容器的大小。
本申请实施例中，将应用界面所在的应用容器从第一显示屏移动至虚拟显示屏后，由于已经建立虚拟显示屏与第二显示屏的映射关系后，可以将虚拟显示屏的内容(即，在应用容器中的应用界面的内容)映射到第二显示屏。
本申请实施例中，在物理多屏设备的场景下，可以实现同一应用界面在不同屏幕尺寸和/或不同分辨率下做无缝切换，可以系统级的解决应用界面在不同物理屏幕设备的显示兼容性问题。无需应用对不同尺寸的显示屏(比如，异形屏)做针对性的适配工作，对异形屏的应用表现力和三方生态有显著提升，大大减少应用针对不同屏幕的适配工作量，非常利于三方应用生态的扩展和推广。
其中，步骤102可以在步骤101之后执行，或者可以在步骤104之后执行。
应用界面所在的应用容器，由于该应用容器之前是在第一显示屏，该应用容器的尺寸与第一显示屏的尺寸适配，而与第二显示屏的尺寸不适配。如果第一显示屏的面积与第二显示屏的面积不同或者第一显示屏的长宽比与第二显示屏的长宽比不同，将该应用容器移动到虚拟显示屏之后，为了让应用容器的尺寸与第二显示屏的尺寸适配，需要调整应用容器，使得调整后的应用容器的长度小于或等于第二显示屏的长度，调整后的应用容器的宽 度小于或等于第二显示屏的宽度。
需要说明的是，由于应用界面在应用容器中，调整了应用容器的尺寸后，该应用界面的尺寸也会相应的调整。一般而言，应用界面的尺寸与应用容器的尺寸相同。
在一个实施例中，第二显示屏可以在执行步骤104之后被点亮，在应用容器的尺寸被调整后，再点亮第二显示屏，使得第二显示屏在点亮后第二显示屏显示的内容是调整后的应用容器中的应用界面的内容，避免用户在第二显示屏中看到应用界面调整的过程，提高用户体验。
在另一个实施例中，第二显示屏可以在执行步骤104之前被点亮。
本申请实施例中，应用界面原本在第一显示屏显示，将应用界面所在的应用容器移动到虚拟显示屏后，可以将虚拟显示屏中的应用容器中的应用界面的内容映射到第二显示屏，从而实现将第一显示屏中显示的应用界面推送到第二显示屏中显示。由于应用容器的长度小于或等于第二显示屏的长度，应用容器的宽度或等于小于第二显示屏的宽度，应用容器中的应用界面的内容映射到第二显示屏时不会出现界面元素显示不全或者重叠的情况，可以避免应用界面从第一显示屏移动到第二显示屏中显示时出现显示异常。
可选的，所述第一显示屏的长宽比与所述第二显示屏的长宽比不同，所述虚拟显示屏的长宽比等于所述第二显示屏的长宽比，所述虚拟显示屏的面积大于或等于所述第二显示屏的面积。
步骤104可以具体可以包括如下步骤：
(11)终端设备调整所述应用容器的长宽比，将所述应用容器的长宽比调整为与所述虚拟显示屏的长宽比相同；
(12)终端设备调整所述应用容器的缩放系数，使得调整后的应用容器的长度等于所述第二显示屏的长度，调整后的应用容器的宽度等于所述第二显示屏的宽度。
本申请实施例中，创建虚拟显示屏时，可以使得虚拟显示屏的长宽比等于第二显示屏的长宽比，在后续调整应用容器的尺寸时，可以直接按照虚拟显示屏的长宽比调整应用容器的长宽比。虚拟显示屏的面积大于第二显示屏的面积，可以保证虚拟显示屏能够承载尺寸较大的容器。
在调整应用容器的长宽比与虚拟显示屏的长宽比相同之后，再调整该应用容器的缩放系数，使得调整后的应用容器的长度等于第二显示屏的长度，调整后的应用容器的宽度等于第二显示屏的宽度，使得调整后的应用容器的尺寸与第二显示屏匹配，使得应用容器中的应用界面的内容能既够填满第二显示屏，又不会出现显示异常，提高应用界面从第一界面推送在第二显示屏进行显示的显示效果。
可选的，虚拟显示屏的面积大于第一显示屏的面积。可以将应用界面所在的应用容器从第一显示屏移动至虚拟显示屏后，虚拟显示屏能够承载该应用容器。
可选的，步骤101中，终端设备创建虚拟显示屏，包括：
终端设备创建表面视图，通过所述表面视图通知设备管理服务创建虚拟显示屏。
本申请实施例中，可以在安卓系统中创建表面视图(surface view)。
在桌面应用(Launcher)检测到第一触摸操作后，可以触发一推管理服务(OplusPuttmanagerService)启动一推服务，触发一堆服务(puttService)启动一推，一推 服务创建表面视图，通过所述表面视图通知设备管理服务(DisplayManagerService)创建虚拟显示屏。
其中，Launcher可以是安卓系统中的桌面启动器，是安卓系统中的主要程序组件之一。设备管理服务是安卓系统中的主要程序组件之一。
可选的，步骤102中，终端设备建立虚拟显示屏与第二显示屏的映射关系，包括：
终端设备将所述表面视图与所述第二显示屏的壳容器绑定，将所述表面视图承载的内容指向所述虚拟显示屏。
本申请实施例中，将表面视图与第二显示屏的壳容器绑定，即建立表面视图与第二显示屏的映射关系。第二显示屏显示的内容为第二显示屏的壳容器的内容。表面视图承载的内容指向虚拟显示屏，可以将虚拟显示屏的内容映射到表面视图。
可以将表面视图与第二显示屏的壳容器绑定，将表面视图承载的内容指向虚拟显示屏，从而实现建立虚拟显示屏与第二显示屏的映射关系。
本申请实施例中，利用虚拟显示屏的内容映射到表面视图上的机制，通过调整应界面所在的应用容器的大小，从而使应用界面完美显示在分辨率较小的物理屏幕(第二显示屏)上，完美解决因物理屏幕尺寸较小带来的应用显示兼容性问题。无需应用对不同尺寸的显示屏(比如，异形屏)做针对性的适配工作，对异形屏的应用表现力和三方生态有显著提升，大大减少应用针对不同屏幕的适配工作量，非常利于三方应用生态的扩展和推广。
其中，一推管理服务、一推服务、第二显示屏的壳容器可以是安卓系统中新建的用于实现启动一推/一推拉回/退出一推的功能的程序组件。
启动一推：用户可以在当前界面通过上滑手势将当前界面上推到第一热区(比如，左上角热区)，抬手之后当前界面从内屏切到外屏显示，此时内屏显示为桌面。
一推拉回：用户通过点击内屏顶部的触摸窗口(比如，把手)或者往下拖动触摸窗口，就可以把二维码界面从外屏拉回内屏显示。
退出一推：应用界面被推到外屏显示时，外屏应用界面顶部有一个触摸窗口，向下拖动外屏的触摸窗口可将该应用界面对应的应用从外屏退出，退到后台。
可选的，第一触摸操作包括：将所述第一显示屏显示的应用界面滑动至第一热区；其中，所述第一热区用于提示将所述应用界面推送到所述第二显示屏显示。
本申请实施例中，第一热区可以用于提示用户：将应用界面推送到该第一热区后，可以实现将应用界面推送到第二显示屏显示。
用户可以通过手指向上滑动应用界面或者向下滑动应用界面，将应用界面向上滑动或者向下滑动至第一热区后，释放手指，即可完成第一触摸操作。
应用界面滑动至第一热区，指的是应用界面的一部分落入第一热区的区域内。
第一热区可以在第一显示屏中预先显示(比如，第一热区可以在检测到第一触摸操作之前就显示)，第一热区也可以在第一触摸操作的过程中显示(比如，第一热区可以在第一触摸操作的滑动距离大于或等于第一阈值的情况下显示)。
可以通过第一显示屏显示的第一热区，来提示用户完成第一触摸操作，从而辅助用户快速将应用界面推送到第二显示屏显示，以促成启动一推的完成。
可选的，所述将所述第一显示屏显示的应用界面滑动至第一热区包括：
在所述第一触摸操作的滑动距离大于或等于第一阈值的情况下，终端设备在所述第一显示屏显示所述第一热区，将所述第一显示屏显示的应用界面滑动至第一热区。
本申请实施例中，第一热区可以在第一触摸操作的过程中显示，及时提醒用户将应用界面推送到第二显示屏显示。
第一阈值可以预先进行设定，可以存储在终端设备的存储器(比如，非易失性存储器)中。
可选的，图1所示的方法还可以包括如下步骤：
在所述第一触摸操作的滑动距离大于或等于第二阈值的情况下，终端设备在所述第一显示屏显示所述第二热区，其中，所述第二热区用于提示将所述应用界面进行浮窗显示。第二热区与第一热区的位置不同。
本申请实施例中，第二热区可以在第一触摸操作的过程中显示，及时提醒用户将该应用界面进行浮窗显示。如果用户将应用界面滑动至第二热区，即可将该应用界面进行浮窗显示。
第二阈值可以预先进行设定，可以存储在终端设备的存储器(比如，非易失性存储器)中。第二阈值与第一阈值可以相等，也可以不相等。
可选的，在执行步骤104之后，还可以执行如下步骤：
终端设备在所述第一显示屏显示触摸窗口，所述触摸窗口用于提示将所述第二显示屏显示的内容移动到所述第一显示屏显示。
其中，触摸窗口可以显示在第一显示屏的任意位置。比如，触摸窗口可以显示在第一显示屏的屏幕边缘(例如，上屏幕边缘、下屏幕边缘、左屏幕边缘、右屏幕边缘中的任一种)。具体的，触摸窗口可以显示在第一显示屏的上屏幕边缘。触摸窗口可以以“把手”的形式显示(可以参见图2)。
用户可以滑动或者点击该触摸窗口，将在第二显示屏显示的应用界面拉回第一显示屏进行显示。在将第一显示屏显示的应用界面推到第二显示屏进行显示之后，可以为用户提供了一个将第二显示屏显示的应用界面拉回第一显示屏进行显示的触摸窗口，从而方便用户将应用界面在第一显示屏和第二显示屏之间进行快速切换，提高用户操作体验。
可选的，在执行步骤104之后，还可以执行如下步骤：
终端设备在所述第一显示屏显示桌面。
本申请实施例中，将第一显示屏显示的应用界面推到第二显示屏进行显示之后，该应用界面不在第一显示屏进行显示，可以在第一显示屏显示桌面。
可选的，终端设备在所述第一显示屏显示桌面之后，还可以执行如下步骤：
在所述第一显示界面检测针对第二应用的触控操作，打开第二应用。
步骤101中，第一显示屏显示的应用界面，可以是第一应用的应用界面。第一应用和第二应用是不同的应用。
在第一显示屏显示桌面之后，用户可以在第一显示屏上进行操作，打开其他应用(第二应用)的应用界面。可以实现在第一显示屏显示一个应用界面，在第二显示屏显示另一个应用界面。可以在两个不同的显示屏分别显示不同的应用，可以应用在需要同时显示两个应用界面的场景。比如，用户将第一显示屏显示的第一应用的应用界面(比如，二维码 界面)推到第二显示屏进行显示后，可以在第一显示屏打开第二应用(比如，娱乐类的应用)。二维码界面可以展示给其他人查看或者进行扫码支付等。既可以满足用户的展示二维码的需求，又可以满足用户的娱乐需求。可以通过终端设备的折叠屏同时满足用户的展示二维码的需求和娱乐需求，又可以保证用户在第一显示屏(内屏)打开第二应用的隐私需求。
请参阅图2，图2是本申请实施例提供的一种将第一显示屏显示的应用界面推送到第二显示屏进行显示的交互示意图。图2中，终端设备为折叠屏手机为例，应用界面以二维码界面为例进行说明。
如图2所示，首先在内屏(第一显示屏)显示二维码界面(应用界面)，用户在内屏上滑该二维码界面(即，退出应用)，此时在内屏的上面显示两个热区：“外屏显示”(第一热区)、“浮窗”(第二热区)。用户继续在内屏上滑该二维码界面，将该二维码界面移动到该“外屏显示”后，用户松开手指，该二维码界面被推往内屏的左上角，然后该二维码界面在内屏消失，二维码界面会被推到外屏显示，内屏显示桌面，且内屏顶部左上角还有一个把手(触摸窗口)显示，通过下拉把手可以把二维码界面重新拉回到内屏(图2中未显示)。
可以通过在内屏进行上滑操作，即可将内屏显示的二维码界面推送到外屏进行显示，提高了应用界面在两个显示屏中进行切换的效率。
请参阅图3，图3是本申请实施例提供的一种将第一显示屏显示的应用界面推送到第二显示屏进行显示的具体流程示意图。
在桌面(Launcher)检测到第一触摸操作(当前界面上滑手势或者针对近期任务卡片的触摸操作，比如，点击近期任务应用卡片上的按钮)后，可以触发一推管理服务(OplusPuttmanagerService)启动一推服务，触发一堆服务(PuttService)启动一推，一推服务创建表面视图，将该表面视图绑定到外屏壳容器，可以通过所述表面视图通知设备管理服务(DisplayManagerService)创建虚拟显示屏。创建虚拟显示之后，一推管理服务将应用(应用界面所在的应用容器)移动到虚拟显示屏，改变应用容器大小，通知进入一推状态，一推服务在内屏顶部显示把手。
其中，安卓系统可以创建一个一推管理服务(OplusPuttmanagerService)，它负责接收Launcher启动一推的消息，拉起一推服务(PuttSerivce)，以及和其他模块进行交互。
一推管理服务(OplusPuttmanagerService)的能力：
a.接收launcher调用，启动一推/一推拉回/退出一推；
b.绑定一推服务(PuttSerivce)/解绑一推服务(PuttSerivce)；
c.启动一推时，把当前应用界面(Activity)所在的应用容器(Task)移到虚拟显示屏；拉回一推时，把应用容器(Task)从虚拟显示屏移回内屏；其中，当前Activity可以理解为当前肉眼看到在前台显示的应用界面；
d.把Activity所在的Task的边界(bounds)大小从内屏的长宽比(比如，内屏的长宽比为21:9)比例调整为外屏尺寸比例(比如，外屏的长宽比为16:9)，除了调整Task的长宽比之外，还可以对Task做等比例缩放(设定缩放系数)，缩放为外屏的等同大小(拉回一推或退出一推时，将Task的长宽比从外屏的长宽比调整为内屏的长宽比，取消缩放系数)；
e.获取应用的自定义屏幕亮度，在进入一推/退出一推过程中通知电源管理服务 (PowerManagerService)，动态改变内屏和/或外屏的亮度；其中，PowerManagerService是安卓原生的电源管理服务，可以负责终端设备的亮灭屏；
f.推出主动亮屏逻辑：依赖大小屏切换模块(DisplayFoldControler)的能力点亮内屏；DisplayFoldControler是安卓原生用于控制折叠屏设备屏幕切换的一个模块；
g.提供业务方注册监听一推状态变化的能力；业务方可以是服务绘制顶部把手的APP，也可以是任何自研应用(比如SystemUI)；一推状态可以包括两种变化：进入一推和退出一推。
h.统一管理应用桌面启动、最近任务启动、进入浮窗、进入分屏等场景导致一推退出(一推退出也可以称为退出一推)的逻辑。这里的逻辑是把推出去在外屏显示的应用，从外屏退出的逻辑。
其中，应用桌面启动，指的是点击桌面该应用图标启动该应用。
当一个应用被推到外屏显示时，如果此时再从内屏桌面启动或者通过最近任务启动卡片以全屏或者分屏或者浮窗启动该应用时，此时该应用会退出一推状态(从外屏退出)，应用在内屏以全屏或者分屏或者浮窗显示。
一堆服务(PuttService)的能力：
a.接收一推管理服务(OplusPuttmanagerService)的绑定和调度；
b.直接跟外屏壳容器(ShellContainer)通信，把自己的表面视图(SurfaceView)挂载/解挂到壳容器中；外屏壳容器是用来显示外屏显示窗口的一个业务模块，可以用来承载SurfaceView对象的一个容器；其中，SurfaceView需要放在外屏的某一个视图(view)容器里面内，所以需要挂载。外屏可以有好多个view容器的，一推服务需要找到在外屏壳容器创建的那个view容器里面去挂载该SurfaceView，把SurfaceView放进去，外屏可以有好多个卡片，外屏壳容器可以移动很多卡片，找到外屏壳容器创建的那个view容器。
c.创建自己的表面视图(SurfaceView)，用此SurfaceView通知设备管理服务(DisplayMangerService)创建虚拟显示屏；
d.调用OplusPuttManagerService，把Activity所在的Task，从内屏移到虚拟显示屏；
e.此时SurfaceView承载内容就是虚拟显示屏里边的内容，而虚拟显示屏里边的内容就是Activity所在的Task，又因SurfaceView在外屏壳容器中显示，所以最终在外屏看到的界面就是从内屏推送的Activity所在的Task。
其中，一推管理服务(OplusPuttmanagerService)是软件上抽象的服务概念，可以认为是一个管理指定业务的模块，一堆服务(PuttService)是继承安卓原生的服务组件。OplusPuttManagerService可以用来管理PuttService的生命周期。
请参阅图4，图4是本申请实施例提供的另一种界面显示方法的流程示意图。如图4所示，该方法可以包括如下步骤。
401，终端设备检测到针对第一显示屏显示的应用界面的第一触摸操作后，创建虚拟显示屏。
402，终端设备建立虚拟显示屏与第二显示屏的映射关系，映射关系用于将虚拟显示屏的内容映射到第二显示屏。
403，终端设备将应用界面所在的应用容器从第一显示屏移动至虚拟显示屏。
404，终端设备调整应用容器，使得调整后的应用容器的长度小于或等于第二显示屏的长度，调整后的应用容器的宽度小于或等于第二显示屏的宽度。
其中，步骤401至步骤404的具体实施可以参见上述步骤101至步骤104的描述，此处不再赘述。
405，终端设备在第一显示屏显示触摸窗口，触摸窗口用于提示将第二显示屏显示的内容移动到第一显示屏显示。
其中，步骤405的具体实施可以参见上述相关的描述，此处不再赘述。
406，终端设备检测到针对触摸窗口的第二触摸操作后，将调整后的应用容器从虚拟显示屏移动至第一显示屏的底层。
本申请实施例中，第二触摸操作可以是滑动操作、点击操作中的至少一种。滑动操作可以包括：向上滑动、向下滑动、向左滑动、向右滑动中的任一种。点击操作可以包括：单击操作、双击操作、三击操作、四击操作中的任一种。例如，第二触摸操作可以是下滑操作。
第一显示屏可以打开很多个应用，每个应用对应一个应用容器，前台应用对应的应用容器位于第一显示屏的顶层。前台应用的应用界面可以被用户肉眼看到。其他后台应用对应的应用容器则不能被用户肉眼看到。
当调整后的应用容器从虚拟显示屏移动至第一显示屏的底层，用户无法在第一显示屏中看到调整后的应用容器中的应用界面，从而提高应用界面的显示效果。
由于调整后的应用容器与第一显示屏的尺寸不匹配，如果将调整后的应用容器从虚拟显示屏移动至第一显示屏的顶层后，在步骤407调整该调整后的应用容器的大小时，会在第一显示屏中看到应用容器的尺寸变化的过程，会影响应用界面的显示效果。
407，终端设备调整该调整后的应用容器，使得二次调整后的应用容器的长度小于或等于第一显示屏的长度，二次调整后的应用容器的宽度小于或等于第一显示屏的宽度。
可以通过一推管理服务(OplusPuttmanagerService)来调整该调整后的应用容器的大小。
本申请实施例中，在物理多屏设备的场景下，可以实现同一应用界面在不同屏幕尺寸和/或不同分辨率下做无缝切换，可以系统级的解决应用界面在不同物理屏幕设备的显示兼容性问题。
其中，所述第一显示屏的长宽比与所述第二显示屏的长宽比不同，所述虚拟显示屏的长宽比等于所述第二显示屏的长宽比，所述虚拟显示屏的面积大于或等于所述第二显示屏的面积。
可选的，步骤407可以包括如下步骤：
(21)终端设备调整所述调整后的应用容器的长宽比，将所述调整后的应用容器的长宽比调整为与所述第一显示屏的长宽比相同；
(22)终端设备调整所述调整后的应用容器的缩放系数，使得二次调整后的应用容器的长度等于所述第一显示屏的长度，二次调整后的应用容器的宽度等于所述第一显示屏的宽度。
本申请实施例中，创建虚拟显示屏时，可以使得虚拟显示屏的长宽比等于第二显示屏的长宽比，在后续调整应用容器的尺寸时，可以直接按照虚拟显示屏的长宽比调整应用容 器的长宽比。虚拟显示屏的面积大于第二显示屏的面积，可以保证虚拟显示屏能够承载尺寸较大的容器。
在调整所述调整后的应用容器的长宽比与虚拟显示屏的长宽比相同之后，再调整所述调整后的应用容器的缩放系数，使得二次调整后的应用容器的长度等于第一显示屏的长度，二次调整后的应用容器的宽度等于第一显示屏的宽度，使得二次调整后的应用容器的尺寸与第一显示屏匹配，使得应用容器中的应用界面的内容既能够填满第一显示屏，又不会出现显示异常，提高应用界面从第二显示屏拉回第一显示屏进行显示的显示效果。
408，终端设备将二次调整后的应用容器从第一显示屏的底层移动到顶层。
本申请实施例中，在调整该调整后的应用容器的尺寸与第一显示屏适配后，再将二次调整后的应用容器从第一显示屏的底层移动到顶层，使得用户在第一显示屏中看到的是二次调整后的应用容器中的应用界面，从而提高应用界面在第一显示屏的显示效果。
在执行步骤408后，二次调整后的应用容器可以位于第一显示屏的顶层。该二次调整后的应用容器可以直接在第一显示屏中显示。该二次调整后的应用容器也可以位于触摸窗口中，用户在下拉该触摸窗口的时候，可以在触摸窗口中显示。
可选的，在执行步骤408之后，还可以执行如下步骤：
终端设备在所述第一显示屏显示第一动画，所述第一动画用于提示将所述应用界面从所述触摸窗口拉回所述第一显示屏。
本申请实施例中，将应用界面从触摸窗口拉回第一显示屏的过程，可以显示第一动画，该第一动画可以显示将应用界面从触摸窗口拉回第一显示屏的动画效果。第一动画可以提示用户正在将应用界面从所述触摸窗口拉回第一显示屏。比如，该第一动画，可以应用界面是从顶部的触摸窗口往下滑的一个过程。
由于在检测到针对触摸窗口的第二触摸操作后，应用容器的尺寸还没有调整好，如果不显示动画，则会在第一显示屏中显示应用容器中的应用界面的尺寸变化的过程，影响显示效果。在显示第一动画的过程中显示应用界面，可以提高应用界面从触摸窗口拉回第一显示屏的显示效果。
可选的，在执行步骤406之后，还可以执行如下步骤：
(31)终端设备解除所述虚拟显示屏与所述第二显示屏的映射关系；
(32)终端设备销毁所述虚拟显示屏。
本申请实施例中，在将调整后的应用容器从虚拟显示屏移动至第一显示屏的底层后，虚拟显示屏中没有任何应用容器，不需要用到该虚拟显示屏，为了降低后台资源开销，可以解除所述虚拟显示屏与所述第二显示屏的映射关系，销毁所述虚拟显示屏。
其中，步骤(31)和步骤(32)可以在“终端设备在所述第一显示屏显示第一动画”之后执行。
可选的，在执行步骤(32)之后，还可以执行如下步骤：
终端设备移除所述触摸窗口。
本申请实施例中，在销毁所述虚拟显示屏之后，该触摸窗口失去了“一推拉回”的作用，移除该触摸窗口，第一显示屏上无需显示一个把手，可以提高第一显示屏的显示效果。
其中，在“终端设备移除所述触摸窗口”之后，第二显示屏(外屏)可以触发回到外 屏壳容器的主界面。外屏壳容器的主界面可以不显示内容。
请参阅图5，图5是本申请实施例提供的一种将应用界面从第二显示屏拉回第一显示屏显示的交互示意图。图5中，终端设备为折叠屏手机为例，应用界面以二维码界面为例进行说明。
如图5所示，用户可以往下拉内屏顶部的触摸窗口(把手)，将外屏的应用界面(二维码界面)拉回内屏显示，外屏黑屏，内屏动画进入。
请参阅图6，图6是本申请实施例提供的一种将应用界面从第二显示屏拉回第一显示屏显示的具体流程示意图。该流程可以包括如下步骤。
(1).将外屏显示的应用界面(Activity)对应的应用容器(Task)，从虚拟显示屏中移除，移动到内屏中的底部位置；
(2).还原应用容器(Task)的大小和缩放系数；
(3).把应用容器(Task)重新拉回前台；
(4).做应用容器(Task)的进场动画；
(5).销毁虚拟显示屏；
(6).外屏触发回到外屏壳容器的主界面；
