技术领域
本申请涉及电子设备技术领域，尤其涉及一种显示屏选择方法及电子设备。
背景技术
目前随着汽车的智能座舱中可配置的显示屏越来越多，在智能座舱中的显示屏上显示更丰富多样的内容的需求也越来越多。但是智能座舱系统中的三方应用较少，因此通过智能座舱系统中的应用能够显示的内容有限，因此将电子设备上显示的内容投屏到智能座舱中的显示屏上进行显示的操作变得越来越普遍。
目前智能座舱系统通常采用一芯多屏的控制机制对智能座舱中的显示屏进行管理，电子设备在投屏到智能座舱中的显示屏时，受到一芯多屏的硬件限制，只能选择投屏到智能座舱，智能座舱系统则默认在主屏例如中控屏上显示来自移动设备的投屏内容。因此该方法选择投屏接收端的灵活性差，导致投屏效率较低，且可能难以满足用户多样化的投屏需求。

具体实施方式
为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施例作进一步地详细描述。其中，在本申请实施例的描述中，以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指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。
为了便于理解，示例性的给出了与本申请相关概念的说明以供参考。
1)电子设备，可以为具有输出显示功能和通信功能的设备。在本申请一些实施例中，电子设备可以是具备一个或多个显示屏的设备。
本申请一些实施例中电子设备可以是便携式设备，诸如手机、平板电脑、具备无线通讯功能的可穿戴设备(例如，手表、手环、头盔、耳机等)、车载终端设备、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。电子设备还可以是智能家居设备(例如，智能电视、智能音箱等)、智能汽车、智能机器人、车间设备、无人驾驶(Self Driving)中的无线终端、远程手术(Remote Medical Surgery)中的无线终端、智能电网(Smart Grid)中的无线终端、运输安全(Transportation Safety)中的无线终端、智慧城市(Smart City)中的无线终端，或智慧家庭(Smart Home)中的无线终端、飞行设备(例如，智能机器人、热气球、无人机、飞机)等。
在本申请一些实施例中，电子设备还可以是还包含其它功能诸如个人数字助理和/或音乐播放器功能的便携式终端设备。便携式终端设备的示例性实施例包括但不限于搭载或者其它操作系统的便携式终端设备。上述便携式终端设备也可以是其它便携式终端设备，诸如具有触敏表面(例如触控面板)的膝上型计算机(Laptop)等。还应当理解的是，在本申请其它一些实施例中，上述电子设备也可以不是便携式终端设备，而是具有触敏表面(例如触控面板)的台式计算机。
2)统一资源定位符(uniform resource locator，URL)，是因特网的万维网服务程序上用于指定信息位置的表示方法。URL通过提供资源位置的一种抽象标志符来对资源进行定位，URL一般由一串字符组成，这些字符可以是字母、数字和特殊符号等。系统定位了一个资源后，可能会对它进行各种各样的操作，这些操作可以抽象为访问、更新、替换、发现属性等，进行这些操作的过程中都需要根据URL进行资源定位。
应理解，本申请实施例中“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A、B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一(项)个”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a、b或c中的至少一项(个)，可以表示：a，b，c，a和b，a和c，b和c，或a、b和c，其中a、b、c可以是单个，也可以是多个。
目前智能座舱系统通常采用一芯多屏的控制机制对智能座舱中的显示屏进行管理，电子设备在投屏到智能座舱中的显示屏时，受到一芯多屏的硬件限制，只能选择投屏到智能座舱，智能座舱系统则默认在主屏例如中控屏上显示来自移动设备的投屏内容。因此该方法选择投屏接收端的灵活性差，导致投屏效率较低，且可能难以满足用户多样化的投屏需求。
上述问题还会导致电子设备只能投屏至智能座舱中的固定显示屏，而无法投屏到智能座舱内的其它显示屏。针对该问题，当前可以在投屏到主屏后设置其它显示屏镜像主屏，镜像后主屏和其它显示屏显示的内容完全一致，各显示屏上不能单独进行其它操作，因此实用性较低。当前还可以在投屏到主屏后，通过在主屏上进行一系列窗口移动操作，将相关内容显示在座舱内其它的任意显示屏上，该方法虽然能够间接实现电子设备投屏到智能座舱中的任一显示屏，但是操作过程十分复杂，效率很低。
当前还存在一种投屏方式是：电子设备在与智能座舱通信连接后，通过将应用迁移至虚拟屏上，再通过虚拟屏将应用画面传递到智能座舱中的显示屏上进行显示。该方法虽然也能实现电子设备投屏到智能座舱中的任意显示屏的效果，但是需要占用电子设备大量的资源，对电子设备的功耗和内存等消耗极大，因此投屏效率和实用性也较低。
因此，当前实现电子设备投屏到智能座舱中的显示屏的方法存在执行过程复杂、投屏效率低、实用性低等问题。
鉴于以上问题，本申请实施例提供一种显示屏选择方法及电子设备，能够在多屏单端(即多个显示屏属于同一设备或控制端)或多屏多端(即多个显示屏属于多个不同设备或控制端)环境下，实现源端设备在多屏中任意选择接受投屏的显示屏的效果，提高投屏的灵活性，还能简便快捷的实现源端设备投屏到所选择的显示屏的效果，能够提高投屏效率，且对源端设备资源占用无影响。
本申请实施例提供的方法可以应用在包括多个电子设备的投屏系统中，该投屏系统中至少包括第一电子设备和第二电子设备。其中，第二电子设备包括多个显示屏或者第二电子设备用于控制和管理多个显示屏。在该投屏系统中，第一电子设备可以作为发起投屏的设备，第二电子设备可以作为接受投屏的设备，第一电子设备可以投屏到第二电子设备的多个显示屏中的任意显示屏。其中，第一电子设备可以将显示的内容投屏到第二电子设备的任一显示屏上进行显示；第一电子设备也可以将同一内容分别投屏到第二电子设备的多个不同的显示屏上进行显示；第一电子设备还可以将不同内容分别投屏到第二电子设备的多个不同的显示屏上分别进行显示。
在本申请一些实施例中，第一电子设备可以为移动电子设备，例如手机、平板等。第二电子设备可以为车辆或车辆中的座舱系统或车辆座舱中的控制设备等，第二电子设备的多个显示屏可以为车辆座舱中配置的显示屏。

在本申请一些实施例中，在第三电子设备作为接受投屏的设备的场景中，第三电子设备可以为处于车辆座舱中的移动电子设备，例如用户携带到座舱中的平板、或者座舱的后装平板等。
在本申请一些实施例中，在第三电子设备作为接受投屏的设备的场景中，第三电子设备可以为车辆座舱中的控制设备，第三电子设备的至少一个显示屏可以为车辆座舱中配置的显示屏。该场景下，第二电子设备和第三电子设备可以分别用于控制和管理车辆座舱中不同的显示屏。例如，第二电子设备可以是用于管理车辆座舱中前排座位对应的显示屏的设备，第三电子设备可以是用于管理车辆座舱中后排座位对应的显示屏的设备。该场景下，座舱系统可以采用多芯多屏或者多设备机制管理多个显示屏。
在另一种可能的情况中，第三电子设备可以作为发起投屏的设备。该情况下，在投屏系统中，除第一电子设备可以投屏到第二电子设备的多个显示屏中的任意显示屏之外，第三电子设备也可以投屏到第二电子设备的多个显示屏中的任意显示屏。其中，第三电子设备可以将同一内容投屏到第二电子设备的任一显示屏上进行显示，该内容可以是第三电子设备的任一显示屏上的内容；第三电子设备也可以将同一内容分别投屏到第二电子设备的多个不同的显示屏上进行显示；第三电子设备还可以将不同内容分别投屏到第二电子设备的多个不同的显示屏上分别进行显示。其中，所述不同内容可以是第三电子设备的同一显示屏上的不同内容，或者，所述不同内容可以分别是第三电子设备的不同显示屏上的内容。在本申请一些实施例中，当第一电子设备和第三电子设备均投屏到第二电子设备的同一显示屏时，第二电子设备可以按照设定规则判断该显示屏上显示来自哪个电子设备的投屏内容，例如可以按照投屏时间的先后顺序、投屏设备(即发起投屏的设备)的优先级顺序等规则选择接受哪个电子设备的投屏，本申请实施例中不做具体限制。
在本申请一些实施例中，在第三电子设备作为发起投屏的设备的场景中，第三电子设备可以为移动电子设备。

下面以应用于车辆座舱场景中为例，对本申请实施例提供的方案进行说明。本申请实施例提供的方案应用于其它场景下的实施方式，可以参照下文提供的方法实现，本申请实施例中不再一一详述。
本申请实施例提供的方案的实施过程主要可以分为两个阶段，分别为显示屏发现和管理阶段以及显示屏选择和投屏执行阶段。下面分别对各个阶段对应的方法进行详细说明。
第一阶段：显示屏发现和管理
本申请以下实施例中，以第二电子设备具有多个显示屏的场景为例，对本申请实施例提供的方法进行说明，其它场景下的方法可以参照下文所述的方法，本申请实施例中不再详述。
本申请实施例中，第二电子设备可以采用一芯多屏机制控制多个显示屏。
在本申请一些实施例中，在车辆座舱场景中，第二电子设备可以是座舱中配置的任一组采用一芯多屏控制机制的显示屏所属的电子设备。第二电子设备作为用于接受投屏的电子设备，可以用于发现和管理座舱内配置的所有可以用于作为投屏接收端的显示屏。当车辆座舱中存在可以用于作为投屏接收端的移动电子设备时，第二电子设备还可以用于管理所述移动电子设备的显示屏。其中，所述移动电子设备包括至少一个显示屏。所述移动电子设备可以在与所述第二电子设备建立通信连接后，将自身的所有显示屏的信息上报至第二电子设备，第二电子设备可以基于移动电子设备上报的显示屏信息，对移动电子设备的显示屏进行管理。可选的，所述第二电子设备与所述移动电子设备可以接入座舱局域网中并基于座舱局域网建立通信连接。
在本申请一些实施例中，在车辆座舱场景中，第二电子设备也可以是座舱中存在的任一可以用于作为投屏接收端的移动电子设备。该情况下，第二电子设备可以在接入座舱局域网后确定座舱中配置的显示屏，并可以用于管理座舱中配置的显示屏。
也就是说，上述方法中，无论第二电子设备是座舱中配置的电子设备还是处于座舱中的移动电子设备，第二电子设备都可以用于管理座舱中存在的所有投屏接收端设备的所有显示屏。
本申请实施例中，第二电子设备可以为所管理的多个显示屏(包括第二电子设备自身的多个显示屏以及座舱中其它移动电子设备的显示屏)分别配置对应的显示屏标记和显示屏指示信息，并建立和保存各显示屏对应的显示屏标记与显示屏指示信息之间的映射关系。其中，显示屏标记可以用于标识显示屏以及显示屏所属的电子设备，显示屏标记可以作为不同电子设备间或者电子设备内部用于识别显示屏及其所属的设备的标识信息，不同电子设备之间可以通过显示屏标记来标识显示屏及其所属的电子设备。借助显示屏标记，各电子设备可以将不同显示屏分别虚拟为设备(显示屏标记可以作为虚拟的设备的标识信息)，便于不同电子设备间区分同一设备的不同显示屏，因此不同电子设备间能够以显示屏为粒度进行相关交互。显示屏指示信息可以用于指示显示屏，显示屏指示信息可以作为电子设备提供给用户的用于指示显示屏的信息。借助显示屏指示信息，电子设备可以将特定的显示屏(例如第二电子设备所管理的显示屏等)指示给用户，以使用户确定对应的显示屏并区分不同的显示屏。例如，当用户需要查看当前存在哪些显示屏时，电子设备可以将当前存在的各显示屏对应的显示屏指示信息显示在显示屏上，则用户可以根据显示屏指示信息确定当前存在的显示屏，用户还可以通过选择显示屏指示信息来选择目标显示屏。对于显示屏标记和显示屏指示信息，也可以理解为：本申请实施例中所述的显示标记为电子设备内部或电子设备之间使用的用于标识显示屏以及显示屏所属的电子设备的信息，本申请实施例中所述的显示屏指示信息是电子设备呈现给用户的用于标识显示屏的信息。
在本申请一些实施例中，显示屏指示信息可以为显示屏名称等用于标识显示屏的信息。在本申请一些实施例中，显示屏标记可以包括显示屏的标识信息和显示屏所属设备的标识信息。其中，显示屏的标识信息可以是显示屏的名称、位置、显示屏标识码(例如可以是第二电子设备为显示屏分配的代码等)等用于唯一标识显示屏的信息，显示屏所属设备的标识信息可以为设备的名称、设备标识码(例如可以是第二电子设备为设备分配的代码等)等信息。
示例性的，图3a为本申请实施例提供的一种车辆座舱中的显示屏的示意图。如图3a中所示，座舱中前排可以配置有采用一芯多屏控制机制的三个显示屏，三个显示屏的显示屏指示信息可以分别为三个显示屏的名称例如仪表屏、中控屏和副驾屏，其中中控屏为主屏，仪表屏和副驾屏为副屏。座舱中后排可以配置有采用一芯多屏控制机制的两个显示屏，两个显示屏的显示屏指示信息可以分别为两个显示屏的名称例如后排左屏和后排右屏，其中后排左屏为主屏，后排右屏为副屏。座舱中后排位置还存在用户携带的移动电子设备例如平板的显示屏，该显示屏的显示屏指示信息可以为该显示屏的名称例如平板显示屏。当然，座舱中各显示屏的名称不限于上述示例的名称，显示屏指示信息可以是第二电子设备分配的名称，也可以是用户手动设置的名称，本申请实施例中不做具体限制。以前排配置的三个显示屏属于电子设备1、后排配置的两个显示屏属于电子设备2、后排的移动电子设备为电子设备3为例，第二电子设备可以是电子设备1～3中的任一电子设备。例如，第二电子设备可以为电子设备1，该情况下电子设备1为电子设备1～3配置的设备标识信息可以分别为标识码1、2、3。对于座舱中配置的显示屏，电子设备1为中控屏、仪表屏、副驾屏、后排左屏、后排右屏配置的显示屏标识信息可以分别为各显示屏的名称，例如可以分别为“中控屏”、“仪表屏”、“副驾屏”、“后排左屏”、“后排右屏”，则中控屏的显示屏标记可以为1-中控屏，仪表屏的显示屏标记可以为1-仪表屏，副驾屏的显示屏标记为1-副驾屏，后排左屏的显示屏标为2-后排左屏，后排右屏的显示屏标记为2-后排右屏。可选的，电子设备1也可以按照主副屏类型及标号为座舱中配置的显示屏分配显示屏标记。例如电子设备1为中控屏、仪表屏、副驾屏、后排左屏、后排右屏配置的显示屏标记可以分别为1-主屏、1-副屏1、1-副屏2、2-主屏、2-副屏。对于电子设备3的显示屏，若电子设备3仅具有一个显示屏，则可以直接将电子设备3的设备标识信息作为该显示屏的显示屏标记；若电子设备3具有多个显示屏，则可以给多个显示屏标号后作为显示屏的标识信息，进而得到显示屏的显示屏标记。例如，当电子设备3具有2个显示屏时，这2个显示屏的显示屏标记可以分别为3-显示屏1、3-显示屏2。
需要说明的是，图3a所示的场景仅作为一种示例，不对本申请实施例提供的方法适用的场景造成限制。实际应用中，座舱内显示屏所属设备的划分、显示屏标记的配置方式等可以灵活设置，本申请实施例中不做具体限制。
基于上述的显示屏指示信息与显示屏标识之间的映射关系，第二电子设备可以对所在空间即座舱中存在的多个显示屏进行信息记录，并可以在需要时进行调用。第二电子设备还可以根据座舱中显示屏的 增减情况对已保存的映射关系进行更新，从而确保所保存的映射关系与座舱中实际存在的显示屏对应。例如，当座舱中加入新的可以用于作为投屏的电子设备后，第二电子设备可以增加保存该电子设备的显示屏的显示屏指示信息与显示屏标记之间的映射关系；当部分电子设备的显示屏被移出座舱时，第二电子设备可以删除这些显示屏的显示屏指示信息与显示屏标记之间的映射关系。
本申请实施例中，作为一种可选的实施方式，第二电子设备可以在投屏过程中，将多个显示屏的显示屏指示信息与显示屏标记之间的映射关系提供给发起投屏的第一电子设备，使得第一电子设备可以将多个显示屏的显示屏指示信息提供给用户，以供用户从中选择接受投屏的目标显示屏。在用户选择目标显示屏后，第一电子设备可以将目标显示屏的显示屏标记返回给第二电子设备，以使第二电子设备确定用于接受投屏的目标显示屏。该方法中，基于显示屏标记，第二电子设备可以将各显示屏虚拟为独立设备并提供给发起投屏的第一电子设备，从而支持用户在多个显示屏中任意选择接受投屏的显示屏，进而实现第一电子设备对多个显示屏中的任意显示屏进行投屏的效果。
作为另一种可选的实施方式，第二电子设备可以在投屏过程中，在接收到来自第一电子设备的投屏请求后，可以根据多个显示屏的显示屏指示信息与显示屏标记之间的映射关系，将多个显示屏的显示屏指示信息直接提供给用户，以使用户在第二电子设备侧选择接受第一电子设备投屏的目标显示屏。其中，当目标显示屏为其它电子设备的显示屏时，第二电子设备可以根据对应的显示屏标记确定对应的其它电子设备，并指示其它电子设备接受投屏。该方式也可以支持用户在多个显示屏中任意选择接受投屏的显示屏，进而实现第一电子设备对多个显示屏中的任意显示屏进行投屏的效果。

当第一电子设备与第二电子设备采用无线通信方式实现投屏时，第一电子设备和第二电子设备可以 基于相同通信协议接入同一局域网中并建立通信连接。当第一电子设备与第二电子设备采用有线通信方式实现投屏时，第一电子设备和第二电子设备可以在被同一传输线(例如数据线等)连接后建立通信连接。
本申请实施例中对第一电子设备与第二电子设备建立通信连接的具体时机不做限制。例如，第一电子设备和第二电子设备可以在第一电子设备显示第一内容之前建立通信连接；或者，第一电子设备可以在显示第一内容之后，在接收第一操作之前，与第二电子设备建立通信连接。或者，第一电子设备可以在接收第一操作之后，在向第二电子设备发送第一投屏请求之前，与第二电子设备建立通信连接。
在步骤S402中，在第一电子设备与第二电子设备采用无线通信方式实现投屏的场景下，第一电子设备可以通过网络向第二电子设备发送第一投屏请求。在第一电子设备与第二电子设备采用有线通信方式实现投屏的场景下，第一电子设备可以通过与第二电子设备间的传输线向第二电子设备发送第一投屏请求。
作为一种可选的实施方式，第一电子设备在第一显示屏上显示第一内容时，可以同时显示用于触发投屏的投屏控件。当接收到作用于投屏控件的操作时，第一电子设备确定发起投屏。若第一电子设备确定第二电子设备可以接受第一电子设备的投屏，则第一电子设备可以向第二电子设备发送第一投屏请求，以请求向第二电子设备所管理的显示屏投屏。

作为另一种可选的实施方式，第一电子设备在第一显示屏上显示第一内容后，可以响应于接收到的用于触发显示投屏控件的操作，显示包含投屏控件的界面，并在接收到作用于投屏控件的操作时，第一电子设备确定发起投屏。若第一电子设备确定第二电子设备可以接受第一电子设备的投屏，则第一电子设备可以向第二电子设备发送第一投屏请求，以请求向第二电子设备所管理的显示屏投屏。
示例2、基于以上示例1所示的场景，用户也可以通过在显示屏上进行操作触发第一电子设备显示图5b中所示的下拉控制界面，该界面中包括用于发起无线投屏的投屏控件。当用户点击该控件时，第一电子设备可以发起对上一界面(即视频应用界面)中的内容的投屏。
在本申请一些实施例中，在第一电子设备向第二电子设备发送第一投屏请求后，用户还需要在第二电子设备管理的多个显示屏中选择接受第一电子设备投屏的目标显示屏。其中，第一电子设备和第二电子设备在将第二电子设备管理的多个显示屏提供给用户，以使用户从中选择接受第一电子设备投屏的目标显示屏时，可以采用如下任一种方式实现：
方式1：第一电子设备和第二电子设备协同提供在第一电子设备侧选择目标显示屏的体验。
该方式中，第一电子设备可以从第二电子设备获取第二电子设备所管理的多个显示屏，并将所述多个显示屏提供给用户。在用户从中选择接受第一电子设备投屏的目标显示屏后，第一电子设备再将目标显示屏指示给第二电子设备。基于该方式，用户可以仅在第一电子设备侧进行投屏相关的控制，便捷性较高。
方式2：第二电子设备提供在第二电子设备侧选择目标显示屏的体验。

上述实施例提供的投屏方式中，接受投屏的目标显示屏是由用户选择的。在本申请一些实施例中，接受投屏的目标显示屏也可以是第一电子设备或第二电子设备自动选择的。则上述图4所示的方法中所述的确定目标显示屏的方法(步骤S403～S406或者步骤S407～S408)可以替换为以下所述的任一种自动选择目标显示屏的方法：
1)在用户在第一电子设备上触发投屏后，或者，在用户在第一电子设备上触发投屏并在第一电子设备提供的设备列表中选择第二电子设备后，第一电子设备可以向第二电子设备发送投屏请求，第二电子设备响应于该投屏请求，可以将设定的默认显示屏(例如中控屏等)作为接受投屏的目标显示屏，或者，若能够识别第一电子设备对应的用户的位置(例如主驾位、副驾位等座位位置)，则可以将该位置对应的显示屏作为接受投屏的目标显示屏。该过程中无需用户手动选择接受投屏的显示屏。
示例7、基于以上示例1所述的场景，当第一电子设备对应的用户为车辆座舱内的主驾位用户时，在主驾位用户点击图5a中所示的视频控件后，第一电子设备可以从显示图5a所示的界面切换为显示图7a所示的界面，在图7a所示的界面中，第一电子设备不再显示视频内容，可以显示投屏中的提示信息。可选的，第一电子设备还可以显示接受投屏的目标显示屏或目标显示屏所属的电子设备等。在主驾位用户点击图5a中所示的视频控件后，如图7b中所示，第二电子设备即车辆可以在主驾位用户所在座位对应的显示屏即中控屏上显示视频内容。因此主驾位用户在触发投屏后无需进行任何操作即可投屏到所在座位对应的显示屏上。
示例8、基于以上示例4所述的场景，当第一电子设备对应的用户为车辆座舱内的主驾位用户时，在主驾位用户在图6d中所示的设备选择界面中选择车辆后，第一电子设备可以从显示图6d所示的界面切换为显示图7a所示的界面。在主驾位用户在图6d中所示的设备选择界面中选择车辆后，如图7b中所示，第二电子设备即车辆可以在主驾位用户所在座位对应的显示屏即中控屏上显示视频内容。
2)在第一电子设备与第二电子设备建立通信连接后，或者在第一电子设备与第二电子设备协同时，用户可以在第一电子设备上选择所在的位置，第一电子设备可以根据用户选择的位置确定用户对应的显示屏。例如用户所在的位置可以通过座舱内的座位区分，则第一电子设备可以向用户提供座舱内的多个座位(例如主驾位、副驾位、后排左侧座位、后排右侧座位等)，用户可以从中选择所在的座位，则第一电子设备可以根据用户选择的座位确定用户对应的显示屏。例如，当副驾位用户选择副驾位作为所在的座位时，第一电子设备可以确定该用户对应的显示屏为副驾屏。则在用户在第一电子设备上触发投屏后，或者，在用户在第一电子设备上触发投屏并在第一电子设备提供的设备列表中选择第二电子设备后，第一电子设备和第二电子设备可以将用户对应的显示屏(即用户选择的位置对应的显示屏)作为接受投屏的目标显示屏。该过程中也无需用户手动选择接受投屏的显示屏。其中，第一电子设备可以在投屏过程中将用户提前选择的位置对应的显示屏作为目标显示屏指示给第二电子设备，或者，第一电子设备可以将用户提前选择的位置指示给第二电子设备，第二电子设备可以根据该位置确定对应的目标显示屏。
在本申请一些实施例中，在第一电子设备投屏到目标显示屏后，用户可以在第一电子设备或第二电子设备上控制切换接受投屏的显示屏。
作为一种可选的实施方式，第一电子设备在投屏后可以显示用于触发切换投屏的切换控件。可选的，该切换控件可以为投屏后第一电子设备所显示的用于指示投屏状态或接受投屏的目标显示屏或接受投屏的目标电子设备的控件，其中，投屏状态为投屏中。当第一电子设备接收到作用于切换控件的操作时，第一电子设备可以将当前接受投屏的设备(即第二电子设备)、当前接受投屏的目标显示屏、该设备所管理的多个显示屏等信息显示给用户。用户可以通过进行相应操作来切换接受投屏的目标显示屏，第一电子设备可以将用户指示的切换后的目标显示屏指示给第二电子设备，则第二电子设备可以切换为在切换后的目标显示屏上显示来自第一电子设备的投屏内容。
示例9、基于以上示例7或示例8所述的场景，切换控件可以为图7a中所示的投屏中的提示信息对应的控件。当第一电子设备接收到用户作用于该控件的操作时，第一电子设备可以显示图9a中所示的显示屏切换界面，该界面中包括当前接受投屏的设备、当前接受投屏的目标显示屏等信息，还可以包括其它控制信息，本申请实施例中不做具体限制。用户可以通过点击用于指示当前接受投屏的目标显示屏的控件，进行目标显示屏的切换。例如，当用户选择将投屏切换到后排右屏时，如图9b中所示，中控屏可以停止显示视频内容，后排右屏上则可以开始显示视频内容。
作为另一种可选的实施方式，在第一电子设备投屏到目标显示屏后，用户可以在目标显示屏上选择 切换投屏到其它显示屏。例如，用户可以通过在目标显示屏上执行设定操作来控制目标显示屏上的投屏内容流转至其它显示屏上，从而实现切换接受投屏的显示屏的效果。再例如，目标显示屏上可以显示用于控制切换显示屏的控件，当接收到用户对该控件进行的操作时，目标显示屏上可以显示其它显示屏的列表，用户可以从中选择切换后接受投屏的显示屏，从而使投屏内容从目标显示屏流转至用户选择的显示屏，实现切换接受投屏的显示屏的效果。
作为另一种可选的实施方式，在第一电子设备投屏到目标显示屏后，用户还可以在目标显示屏上通过手势操作将投屏内容流转至其他显示屏。例如，目标显示屏为后排左屏时，通过用户的三指右滑操作，后排左屏的投屏内容可以流转至后排右屏。
基于上述实施例提供的方法，第一电子设备、第二电子设备之间能够基于无线通信方式，实现第一电子设备至第二电子设备关联的任一显示屏的投屏。其中，在投屏方式上，第一电子设备、第二电子设备之间可以采用DLNA投屏、无线投屏等方式。在目标屏选择方式上，第一电子设备、第二电子设备可以支持在任一设备侧进行选择。在数据传输方式上，可以是投屏内容直接传输到投屏接收端的方式，也可以投屏内容的地址传输到投屏接收端使得投屏接收端根据地址获取投屏内容的方式。在投屏效果上，第一电子设备可以投屏到第二电子设备的任意显示屏上，也可以投屏到第二电子设备所连接的其它电子设备的任意显示屏上，还可以在投屏后在任一电子设备上控制切换接受投屏的显示屏。因此，上述实施例提供的实现投屏的方法十分灵活，且能够以显示屏为粒度进行投屏，而不是以设备为粒度进行投屏，因此能够灵活选择接受投屏的显示屏，实用性更强。此外，上述方法在投屏过程中对第一电子设备的资源占用基本无影响。
按照上述实施例提供的方法，同一电子设备中不同应用的内容能够分别投屏到其它电子设备所管理的不同显示屏上，不同电子设备中的内容也能够分别投屏到其它电子设备所管理的不同显示屏上。因此，本申请实施例提供的方案能够在多屏多端环境下，实现单设备或多设备同时投屏到多个显示屏的效果，实用性较高。
示例性的，如图10a所示，手机1中显示视频界面，手机2中显示通话界面，在车辆的座舱内包括中控屏、副驾屏、后排左屏、后排右屏时，手机1和车辆可以按照上述实施例中所述的第一电子设备投屏至第二电子设备管理的显示屏的方法，将视频界面中的视频内容投屏至中控屏进行显示，手机2和车辆可以按照上述实施例中所述的第一电子设备投屏至第二电子设备管理的显示屏的方法，将通话界面投屏至后排右屏进行显示。其中，手机1和手机2可以同时进行投屏且互不干扰。则如图10b所示，车辆座舱内的中控屏上可以显示视频内容，后排右屏上可以显示通话界面。
