技术领域
本申请实施例涉及电子技术领域，并且更具体地，涉及一种切换窗口的方法和电子设备。
背景技术
在用户使用电子设备的过程中，经常需要将一个电子设备的显示界面显示在另一电子设备中。例如，手机向平板投屏，手机的显示界面可以显示在平板中，这种情况下，手机作为投屏设备，平板作为被投屏设备。
然而包括手机的投屏窗口可能会遮挡平板的部分显示内容，所以用户可以通过操作使平板最小化显示投屏窗口，在需要时重新将投屏窗口显示出来，从而可以不影响用户对平板的使用。但是该投屏窗口切换过程需要用户频繁操作，影响了用户的体验。
发明内容
本申请实施例提供一种切换窗口的方法和电子设备，以期在检测到电子设备的状态发生变化时，将投屏的电子设备的显示屏作为被投屏的另一电子设备的拓展屏，且被投屏的另一电子设备中可以显示拓屏图标，而不具体显示投屏窗口，以减少用户的部分操作，从而可以提升用户体验。

应理解，该第一数据可以是第一电子设备向第二电子设备投屏的数据。该第一显示界面可以是投屏窗口的显示界面。
本申请实施例中，第一电子设备向第二电子设备投屏后，当第一电子设备确定第一电子设备或第二电子设备从第一状态切换至第二状态时(例如从普通态切换至支架态)，此时未切换状态的电子设备也处于第二状态，那么第一电子设备可以自动暂停向第二电子设备投屏并显示向所述第二电子设备投屏的第一显示界面。也就是说，视觉上第一电子设备的显示屏可以作为第二电子设备的拓展屏。该技术方案可以在电子设备状态发生变化时自动暂停投屏，避免用户手动操作，且第一电子设备的显示屏可以作为第二电子设备的拓展屏，能够给用户带来更广阔的视觉效果，提升了用户的体验。进一步地，第一电子设备暂停投屏，从而可以节省功耗和带宽。
本申请实施例中，当电子设备的状态发生变化时，第一电子设备可以继续向第二电子设备投屏，且接收第二电子设备发送的第一数据，并根据第一数据显示第一显示界面，从而可以便捷地将投屏窗口切换至第一电子设备中显示，从而在投屏窗口重新切换回第二电子设备中时，由于投屏未中断所以无需重新加载投屏数据，进而可以降低延迟。

在介绍本申请实施例的技术方案之前，首先简单介绍一下本申请可能会涉及的一些专业术语。
投屏：将电子设备A中的显示屏显示的画面，以窗口或全屏的形式显示在电子设备B的显示屏中。
拓屏：电子设备A可以暂停向电子设备B投屏，电子设备A的屏幕作为电子设备B的拓展屏；或者电子设备B将电子设备A投屏的内容显示在电子设备A中，电子设备A的屏幕作为电子设备B的拓展屏。此时，电子设备B的鼠标可以移动至电子设备A中，可选地，电子设备B的显示屏中显示拓屏图标。
支架态：电子设备的y轴的角度α1满足公式一，第一预设角度<α1≤第二预设角度，且，在预设时间t内，该角度α1的变化范围小于第一预设值。例如，该第一预设角度可以为30°，该第二预设角度为90°，该时间t为1s，该第一预设值为0.03。应理解，该第一预设角度、第二预设角度、时间t和预设值的具体取值还可以为其他值，根据第一预设角度和/或第二预设角度的设定方式不同，前述的角度α1的判定方法也可以有其它方法，本申请实施例不予限定。本申请实施例中，电子设备放置在支架上，可以理解为电子设备处于支架态。关于支架态的具体描述可以参见下文，此处暂不详述。
中间态：在预设时间t内，该角度α1的变化范围大于或等于第一预设值且小于或等于第二预设值。例如，第一预设值为0.03，第二预设值为5。应理解，该中间态还可以称为过渡态、临近切换态等等。
普通态：电子设备的y轴的角度α1不满足公式一，且预设时间t内，该角度α1的变化范围大于第二预设值。本申请实施例中，将电子设备从支架上移开，可以理解为电子设备从支架态变为普通态。
图3是本申请实施例提供的一组图形用户界面(graphical user interface，GUI)的示意图。其中，从图3中的(a)至(b)示出了手机200a在平板200b上投屏的过程。
本申请实施例中，平板200a可以外接键盘200c和鼠标200d。例如，该键盘200c、鼠标200d可以通过有线或无线方式与平板200b建立连接关系，从而用户可以便捷的在平板200b中进行办公等操作。
应理解，在手机200a向平板200b投屏之前，手机200a可以和平板200b建立连接关系。例如，手机和平板可以是通过无线、有线等方式建立连接关系。
参见图3中的(a)，该GUI为手机200a向平板200b投屏之后，手机200a的显示界面210和平板200b的显示界面240。该显示界面240中可以包括手机200a的投屏窗口221，其中，该投屏窗口221中可以包括状态栏222和显示界面231，该状态栏222中可以包括手机当前显示的界面所属的应用程序的名称，例如，华为视频，该状态栏222中还可以包括用于使投屏窗口221变化的最小化按钮223、最大化按钮224和关闭按钮225。
应理解，在一些示例中，该显示界面231和手机的显示界面210相同。也就是说，手机中的当前显示界面通过该显示界面231显示在平板200b中。
在其它一些示例中，该显示界面231也可以和手机的显示界面210不同，换句话说，手机虽然有部分界面投屏到平板，但是手机仍然可以显示和投屏的界面不同的界面，例如，在平板上打开手机的 应用A，既手机投屏到平板应用A的界面，然后手机用户可以打开应用B，在手机上显示应用B的界面，类似现有技术中的异源投屏场景。
在一些示例中，手机200a向平板200b投屏之后，在预设时间内未检测到用户的操作，则手机200a可以熄屏，从而可以节省手机200a的功耗。
当平板200b检测到用户使用鼠标点击最小化按钮223的操作之后，可以显示图3中的(b)所示的GUI。
参见图3中的(b)，平板200b的显示界面240中可以显示投屏图标230，从而可以将该投屏窗口221最小化显示。
当平板200b检测到用户通过鼠标200d点击该投屏图标230的操作后，可以将该投屏窗口221重新显示在显示界面240中。由于用户在使用平板200b时，投屏窗口221可能会遮挡平板200b的部分显示内容，所以用户可以将该投屏窗口221最小化显示，在需要时重新将投屏窗口显示出来，从而可以不影响用户对平板200b的使用。但是该投屏窗口切换过程需要用户频繁操作，影响了用户的体验。
有鉴于此，本申请实施例提供一种切换窗口的方法，该技术方案可以在投屏的电子设备或被投屏的另一电子设备的状态发生变化时，将投屏的电子设备的显示屏作为被投屏的电子设备的拓展屏，且被投屏的另一电子设备中可以显示拓屏图标，而不具体显示投屏窗口，从而可以避免用户过多的切换操作。
如图3所示，在手机向平板投屏之后，手机的显示界面可以以投屏窗口的形式显示在平板的显示界面中，还可以以最小化方式(投屏图标)体现在平板的显示界面中。下文将结合图4、图5分别介绍这两种技术方案。
图4是本申请实施例提供的另一组GUI的示意图。其中，图4中的(a)至(b)示出了投屏窗口在平板300b中变化的过程。
参见图4中的(a)，该GUI为手机300a向平板300b投屏之后，手机300a的显示界面310和平板300b的显示界面340。
其中，手机300a在向平板300b投屏之后，为了节省功耗，可以对显示屏进行熄屏。或者，手机300a也可以继续处于亮屏状态，本申请实施例不予限定。
应理解，平板300b也可以外接键盘或鼠标。平板300b的显示界面340可以参见前文中显示界面240的相关描述，为了简洁，此处不再赘述。
在一种情况下，平板300a可以处于支架态，当手机300a从普通态变为支架态时，则手机300a和平板300b可以显示如图4中的(b)所示的GUI。
例如，手机投屏后，为了节省功耗，可以对显示屏进行熄屏，当用户将手机放置在手机的支架上，手机可以通过检测y轴的角度，确定手机从普通态变为支架态。
应理解，当手机放置在手机的支架上时，手机的y轴的角度α1需满足上述支架态的定义。
应理解，本申请实施例中，平板300a处于支架态，可以理解为平板300a被放置在支架上。例如，用户希望使用平板300a进行办公，则可以对平板300a外接键盘和鼠标，并将平板300a放置在平板的支架上。
还应理解，当平板放置在平板的支架上时，平板的y轴的角度α1需满足上述支架态的定义。
在另一种情况下，手机可以处于支架态，当平板300b从普通态变为支架态时，则手机300a和平板300b可以显示如图4中的(b)所示的GUI。
例如，手机向平板投屏后，被用户放置在手机的支架上，用户将正在使用的平板放置在平板的支架上，则平板可以从普通态变为支架态。
参见图4中的(b)，手机300a从熄屏状态到亮屏状态，并显示显示界面311，平板300b中的投屏窗口320消失，可选的，在平板300b上显示拓屏图标330。在一些示例中，鼠标可以移动至手机300a的显示界面311中，用户可以通过鼠标操控手机300a。也就是说，手机300a的显示屏可以作为平板300b的拓展屏。
应理解，通过鼠标控制手机可以是基于蓝牙或WI-FI等近场通讯实现。在用户操作鼠标时，平板会获取鼠标指针坐标，当手机的显示屏不是平板的拓展屏时，鼠标指针坐标超出平板控制区域(显示屏)时，平板会将鼠标指针显示在控制区边缘(如左边缘)。本申请实施例中，手机的显示屏作为平板的拓展屏，当平板对应的鼠标指针坐标，超出平板控制区域一侧时(如左边缘/右边缘/上边缘/下边 缘)，平板会将鼠标数据(包括鼠标坐标数据及操作数据)通过蓝牙或WI-FI等发送给手机，手机将接收到的鼠标数据映射成手机的对应位置，并在显示界面上显示鼠标指针以及在手机侧执行对应的鼠标操作。从体验上形成一种用户使用鼠标指针从平板边缘无缝移动到手机的效果。
在一些示例中，手机和平板之间的距离小于或等于预设距离。
在一些示例中，当手机位于平板的左侧时，该拓屏图标可以位于平板的左边缘，且拓屏图标中用于表示手机的图形位于平板图形的左侧。当手机位于平板的右侧时，该拓屏图标可以位于平板的右边缘，且拓屏图标中用于表示手机的图形位于平板图形的右侧。或者，该拓屏图标还可以位于平板底部的任务栏中，本申请实施例不予限定。
例如，手机和平板建立投屏关系后，手机可以将自己的方位信息通过蓝牙发送给平板，从而平板可以确定手机的方位。
在一些示例中，当用户使用鼠标点击拓屏图标330的操作之后，平板300b的显示界面340中将再次显示投屏窗口320。
应理解，该平板300b也可以替换为个人计算机PC，该手机300a也可以替换为平板，或者两台设备可以是同类型设备，本申请实施例不予限定。
本申请实施例中，在手机与平板建立投屏关系后，手机的显示界面可以以投屏窗口的形式显示在平板的显示界面中，当手机和平板中的一个处于支架态，另一个从普通态变为支架态时，手机自动暂停向平板投屏，平板中的投屏窗口可以关闭，并显示拓屏图标，此时，手机的显示屏可以是作为平板的拓展屏。该技术方案可以根据手机或平板的姿态变化自动暂停投屏，无需用户手动操作，从而可以提升用户使用多屏协同的体验。
或者，本申请实施例中，当电子设备的状态发生变化时，手机可以继续向平板投屏，且接收平板发送的第一数据，并根据第一数据显示投屏的界面，从而可以便捷地将投屏窗口切换至手机中显示，从而在投屏窗口重新切换回平板中时，由于投屏未中断所以无需重新加载投屏数据，进而可以降低延迟。
在一些情况下，在手机和平板均处于支架态时，可能会出现用户需要使用手机或平板，从而将其从支架上移开的情况。例如，用户将手机从支架上移开，放在桌子上或装进口袋；或者，用户将平板从支架上移开。在这种情况下，手机可以重新进入熄屏状态，并自动恢复向平板投屏，则投屏窗口将重新显示在平板的显示界面中。
示例性地，在图4中的(b)所示的场景下，当手机300a从支架态变为普通态时，手机300a和平板300b可以显示如图4中的(a)所示的GUI。
在另一个示例中，在图4中的(b)所示的场景下，当平板300b从支架态变为普通态时，手机300a和平板300b可以显示如图4中的(a)所示的GUI。
该技术方案中，当手机和平板均处于支架态，其中一个从支架态变为普通态时，投屏窗口可以重新显示在平板的显示界面中。从而可以根据手机或平板的姿态变化便捷的自动恢复投屏，避免用户手动操作，提升了用户使用多屏协同的体验。
在另一些示例中，当手机从支架态变为普通态，投屏窗口重新切换至平板的显示界面中。此时，平板可以开启摄像头，以检测是否存在人像。当平板未检测到人像时，平板可以锁屏，以保护用户隐私，平板还可以熄屏，以节省功耗。当平板检测到人像时，可以继续保持当前状态。或者进一步地，当平板检测到人像时，可以从存储的人像中确定检测的人像是否是机主，若是平板可以继续保持当前状态，若不是平板可以锁屏或熄屏。
在另一个示例中，当平板从支架态变为普通态，投屏窗口重新切换至平板的显示界面中。若手机处于未熄屏状态下，则手机可以开启摄像头，以检测是否存在人像。当手机未检测到人像时，可以锁屏，以保护用户隐私，手机还可以熄屏，以节省功耗。当手机检测到人像时，可以继续保持当前状态。或者进一步地，当手机检测到人像时，可以从存储的人像中确定检测的人像是否是机主，若是，则手机可以继续保持当前状态，若不是，则手机可以锁屏或熄屏。

参见图5中的(a)，该GUI为手机400a向平板400b投屏之后，手机400a的显示界面410和平板400b的显示界面450。
其中，手机400a在向平板400b投屏之后，为了节省功耗，可以对显示屏进行熄屏，相应的，该显示界面410中不显示任何界面元素。用户为了使手机的投屏窗口不遮挡平板的显示界面，可以将投屏窗口最小化显示，也就是在平板的显示界面450中显示投屏图标430，当用户点击该投屏图标430时，可以重新将手机的投屏窗口重新显示在显示界面450中。
应理解，平板400b也可以外接键盘、鼠标，从而方便用户在平板上办公。

其中，电子设备的支架态可以理解为，电子设备在竖屏状态下的y轴的角度α1满足公式一：第一预设角度<α1≤第二预设角度，且，在预设时间t内，该角度α1的变化范围小于第一预设值。例如，该第一预设角度可以为30°，该第二预设角度为90°，该时间t为1s，该第一预设值为0.03。应理解，该第一预设角度、第二预设角度、时间t和预设值的具体取值还可以为其他值，本申请实施例不予限定。
示例性地，参见图9，电子设备可以通过惯性测量单元(inertial measurement unit，IMU)、传感器等来获取电子设备的y轴的角度。
本申请实施例中，参见图10，当手机100a被放置到手机的支架100c上时，可以理解为手机100a处于支架态。应理解，当手机100a位于支架100c上时，手机100a的y轴的角度α1满足上述公式一。
应理解，电子设备还可以通过IMU获取x轴，z轴的角度。
电子设备的普通态可以理解为，电子设备的y轴的角度α1不满足公式一，且预设时间t内，该角度α1的变化范围大于第二预设值。
示例性地，该第二预设值可以是5，6等。
例如，该电子设备为手机，当用户手持手机使用时，电子设备的y轴的角度大概率不满足上述公式一，且手机的角度变化范围较大，此时，可以理解为电子设备处于普通态。
在一些情况下，当电子设备被放置在支架上时，也就是说，电子设备处于支架态时，用户可能会不小心触碰到电子设备，或者，由于桌子的抖动等，使得电子设备的y轴的角度发生微小的变化。此时，电子设备可能会检测到y轴的角度发生变化，从而错误的判断电子设备从支架态变为普通态，进而暂停投屏。在这种情况下，用户并不希望电子设备暂停投屏，从而会影响用户的体验。为了使得电子设备在支架态和普通态之间平缓过渡，避免电子设备的误判，本申请中引入了电子设备的中间态。
中间态可以理解为，在预设时间t内，该电子设备的y轴的角度α1的变化范围大于或等于第一预设值且小于或等于第二预设值。
示例性地，该预设时间t为1s，该第一预设值为0.03，该第二预设值为5。也就是说，在1s内，电子设备的y轴的角度的变化量在0.03至5之间时，电子设备处于中间态。
本申请实施例中，当电子设备从前一个状态变为中间态时，电子设备保持现态不变。
在一个示例中，电子设备处于支架态，当电子设备通过IMU检测到1s内，y轴的角度的变化量处于0.03至5之间，则可以确定电子设备变为中间态，则电子设备仍保持支架态下的状态。例如，参见图4中的(b)，手机300a处于支架态，当手机300a检测到手机变为中间态时，手机可保持当前现状。
在另一个示例中，电子设备处于普通态，当电子设备通过IMU检测到1s内，y轴的角度的变化量处于0.03至5之间时，可以确定电子设备变为中间态，则电子设备仍保持普通态下的状态。例如，参见图4中的(a)，手机300a处于普通态，当手机300a检测到手机变为中间态时，手机可保持当前现状。
在另一些示例中，当电子设备处于横屏状态下，在确定电子设备的状态是否发生变化时，可以使用z轴的角度代替y轴的角度，即通过获取z轴的角度β1，来确定电子设备的状态。
本申请实施例中，通过设置中间态，使得电子设备可以在支架态和普通态之间平滑切换，避免由于一些误触或抖动使得电子设备切换投屏状态，从而可以为用户使用带来一定的容错性，进而提升了 用户的体验。
图11至图12以第一电子设备向第二电子设备投屏为例进行说明。示例性地，该第一电子设备可以是前文中的手机，该第二电子设备可以是前文中的平板。
图11是本申请实施例提供的一种切换窗口的方法的示意性流程图。如图11所示，该方法1100可以应用于第一电子设备，第一电子设备处于向第二电子设备投屏的场景下，第二电子设备显示的第一显示界面为第一电子设备向第二电子设备投屏的界面，该方法1100可以包括步骤1110至步骤1120。
应理解，该第一显示界面可以是第一电子设备向第二电子设备投屏的投屏窗口对应的显示界面。
1110，第一电子设备确定第一电子设备或第二电子设备从第一状态切换至第二状态，其中，未切换状态的电子设备处于第二状态。
应理解，在步骤1110之前，第一电子设备可以和第二电子设备建立投屏连接，例如，第一电子设备可以和第二电子设备通过无线、有线等方式建立连接关系，本申请实施例对于该具体建立连接关系的方式不予限定。
该第一状态可以是前文中的普通态，该第二状态可以是前文中的支架态。
该步骤1110可以理解，第一电子设备和第二电子设备中的一个处于支架态，另一个从普通态切换至支架态。
1120，第一电子设备暂停向第二电子设备投屏并且第一电子设备显示第一显示界面，或者，第一电子设备根据从第二电子设备接收的第一数据显示第一显示界面。
示例性地，参见图4，该第一电子设备可以是手机，该第二电子设备可以是平板，当手机确定平板和手机中一个处于支架态，另一个从普通态切换至支架态时，手机可以显示向平板投屏的显示界面310并暂停向平板投屏，或者，手机根据从平板接收的数据显示第一显示界面。
此时，平板中的鼠标或光标可以移动至手机中，用户可以通过鼠标操控手机。也就是说，手机此时可以作为平板的拓展屏。
应理解，该第一数据可以是第一电子设备向第二电子设备投屏的数据，例如，可以是显示界面、视频流等等。这种情况下，在电子设备的状态发生变化时，第二电子设备将第一电子设备的显示屏作为扩展屏，第二电子设备将第一数据形成的显示界面显示在第一电子设备，从而可以便捷地将投屏窗口切换至第一电子设备中显示，从而在投屏窗口重新切换回第二电子设备中时，由于投屏未中断所以无需重新加载投屏数据，进而可以降低延迟。
示例性地，当平板检测到用户点击拓屏图标的按钮时，平板可以重新将投屏窗口切换回平板中显示，此时，由于投屏未中断所以无需重新加载投屏数据，进而可以降低延迟。
本申请实施例中，第一电子设备向第二电子设备投屏后，当第一电子设备确定第一电子设备或第二电子设备从第一状态切换至第二状态时(例如从普通态切换至支架态)，此时未切换状态的电子设备也处于第二状态，那么第一电子设备可以自动暂停向第二电子设备投屏并显示向所述第二电子设备投屏的第一显示界面。也就是说，视觉上第一电子设备的显示屏可以作为第二电子设备的拓展屏。该技术方案可以在电子设备的状态发生变化时自动暂停投屏，避免用户手动操作，且第一电子设备的显示屏可以作为第二电子设备的拓展屏，给用户带来更广阔的视觉效果，提升了用户的体验。进一步地，第一电子设备暂停投屏，从而可以节省功耗和带宽。
在一些实施例中，在第一电子设备显示第一显示界面并暂停向第二电子设备投屏之前，该方法1100还可以包括：
确定第一电子设备的显示屏是否点亮；
若确定显示屏未点亮，则点亮显示屏。
示例性地，参见图5，当手机确定平板和手机中一个处于支架态，另一个从普通态切换至支架态时，手机可以先确定手机的显示屏是否点亮，若未点亮，即手机处于熄屏状态，则可以将显示屏点亮，以显示显示界面420。
该技术方案可以在需要时点亮显示屏，从而可以节省电子设备的功耗。
在一些实施例中，若第一电子设备确定第一电子设备从第一状态切换至第二状态，该方法1100还可以包括：
向第二电子设备发送第一指示信息，第一指示信息用于指示第一电子设备从第一状态切换至第二状态。
示例性地，手机可以通过自身的IMU、传感器等来确定是否从普通态切换至支架态。
本申请实施例中，当第一电子设备确定自身的状态发生变化时，将该状态变化的指示信息发给第二电子设备，从而有利于第二电子设备执行切换策略。
在一些实施例中，第一电子设备确定第二电子设备从第一状态切换至第二状态，包括：
接收第二电子设备发送的第二指示信息；
当第二指示信息指示第二电子设备从第一状态切换至第二状态时，确定第二电子设备从第一状态切换至第二状态。
本申请实施例中，当平板从第一状态切换第二状态时，平板可以将该状态变化的第二指示信息发送给手机，手机接收到该第二指示信息后，可以确定平板的状态发生变化，进而执行相应的操作。
在一些实施例中，第一状态和/或第二状态为电子设备的物理形态。
示例性地，该第一状态、第二状态为电子设备的物理形态可以理解第一状态、第二状态为电子设备的姿态，例如，电子设备被放置在桌面上，或者以一定角度被放置在某个物体上，或者被用户拿在手上使用等等。
在一些实施例中，第二状态为支架态，支架态用于指示电子设备处于相对稳定的状态，或者，支架态为电子设备处于被放置在支架上的状态；
第一状态为普通态，普通态用于指示电子设备处于相对不稳定的状态，或者，普通态为电子设备处于不被放置在支架上的状态。
可以理解的是，支架态可以用于指示电子设备处于相对稳定的状态，例如，电子设备以一个固定姿势被放置，，或者以某个角度被放置在另一个物体上，或者，电子设备处于被放置在支架上的状态。普通态可以用于指示电子设备处于相对不稳定的状态，例如，电子设备被用户拿在手上使用，其不具有一个固定姿势，此时，电子设备的姿态处于不稳定的状态，或者，电子设备处于不被放置在支架上的状态。
在一些实施例中，第二状态为第一电子设备的第一方向的角度大于第一预设角度且小于或等于第二预设角度，且在预设时间内，角度的变化范围小于第一预设值；第一状态为角度小于或等于第一预设角度或大于第二预设角度，且在预设时间内，角度的变化范围大于第二预设值。
应理解，该第二状态可以为支架态，该第一状态可以是普通态，关于该支架态和普通态可以参见前文中的相关描述，为了简洁，不再赘述。
在一些实施例中，该方法1100还可以包括：
在预设时间内，第一电子设备确定角度的变化范围大于或等于第一预设值且小于或等于第二预设值；
第一电子设备确定第一电子设备处于第三状态，在第三状态下，第一电子设备继续显示第一显示界面。
示例性地，参见图8，该第一状态可以是普通态，该第二状态可以是支架态，该第三状态可以是中间态。
本申请实施例中，通过引入中间态，使得电子设备可以在支架态和普通态之间平滑切换，避免由于一些误触或抖动使得电子设备切换投屏状态，从而可以为用户使用带来一定的容错性，进而提升了用户的体验。
在一些实施例中，第二电子设备的光标可移动至第一电子设备的显示屏中。
本申请实施例中，在第一电子设备暂停向第二电子设备投屏后，第一电子设备可以作为第二电子设备的拓展屏，此时用户可以用户鼠标控制第一电子设备。
在一些实施例中，该方法1100还可以包括：
第一电子设备确定第二电子设备从第二状态切换至第一状态；
第一电子设备熄灭显示屏并继续向第二电子设备投屏。
在一个示例中，参见图4，当手机确定平板从支架态切换回普通态时，手机可以将显示屏熄灭，并恢复向平板的投屏，平板中显示投屏窗口320。
在另一个示例中，参见图5，当手机确定平板从支架态切换回普通态时，手机可以将显示屏熄灭，并恢复向平板的投屏，平板中显示投屏图标430，此时，投屏窗口最小化显示在平板中。
本申请实施例中，当确定第二电子设备从第二状态切换回第一状态时，第一电子设备可以自动恢 复向第二电子设备的投屏，无需用户手动操作，从而可以将投屏窗口显示在第二电子设备中。此外，第一电子设备熄屏可以进一步节省功耗。
在一些实施例中，该方法1100还可以包括：
第一电子设备确定第一电子设备从第二状态切换至第一状态；
第一电子设备继续显示第一显示界面并继续向第二电子设备投屏。
本申请实施例中，当确定第一电子设备的从第二状态切换回第一状态时，可以自动恢复向第二电子设备投屏，从而可以将投屏窗口重新显示在第二电子设备中。此外，第一电子设备继续显示第一显示界面，可以不影响用户对于第一电子设备的使用。
在一些实施例中，在第一电子设备熄灭所述显示屏之前，该方法1100还可以包括：
第一电子设备确定打开摄像头未获取到用户的图像。
本申请实施例中，当第一电子设备打开摄像头未获取到用户的图像时，可以熄屏，以节省功耗。
在一些实施例中，第一电子设备暂停向第二电子设备投屏并显示第一显示界面，或者，第一电子设备根据从第二电子设备接收的第一投屏数据显示第一显示界面，包括：
当确定第一电子设备与第二电子设备之间的距离小于或等于预设距离时，第一电子设备暂停向第二电子设备投屏并显示第一显示界面，或者，第一电子设备根据从第二电子设备接收的第一投屏数据显示第一显示界面。
本申请实施例中，第一电子设备和第二电子设备之间的距离应在预设距离范围内，从而可以避免用户在持有第一电子设备距离第二电子设备较远的情况下，依然切换投屏状态对用户造成困扰。
图12是本申请实施例提供的另一种切换窗口的方法的示意性流程图。如图12所示，该方法1200可以应用于第二电子设备，第二电子设备处于被第一电子设备投屏的场景中，该方法1200可以包括步骤1210至步骤1220。
1210，第二电子设备确定第二电子设备或第一电子设备从第一状态切换至第二状态，其中，未切换状态的电子设备处于第二状态；
该步骤1210中，第一电子设备可以向第二电子设备投屏，第二电子设备处于被投屏的状态下。
该第一状态可以是前文中的普通态，该第二状态可以是前文中的支架态。
该步骤1210可以理解，第一电子设备和第二电子设备中的一个处于支架态，另一个从普通态切换至支架态。
1220，第二电子设备显示第一图标，第一图标用于指示第一电子设备的显示屏作为第二电子设备的拓展屏。
示例性地，该第一图标可以是拓屏图标。该拓屏图标还可以称为拓展图标、扩展图标等等。
在一个示例中，参见图4，当平板确定平板或手机的状态从普通态切换至支架态时，平板可以显示拓屏图标330。应理解，该拓屏图标还可以是其他形式的图标，本申请不予限定。
在一些可能的实现方式中，当手机位于平板的左侧时，该第一图标可以位于显示界面的左侧；当手机位于平板的左侧时，该第一图标可以位于显示界面的左侧。
本申请实施例中，第一电子设备向第二电子设备投屏后，当第二电子设备确定第一电子设备或第二电子设备从第一状态切换至第二状态时(例如从普通态切换至支架态)，此时未切换状态的电子设备也处于第二状态。那么，第二电子设备可以显示用于指示第一电子设备的显示屏作为第二电子设备的拓展屏的第一图标。此时，第一电子设备暂停投屏，第二电子设备中的投屏窗口关闭，第二电子设备中只需显示第一图标即可，且第一电子设备可以作为第二电子设备的拓展屏，给用户带来更广阔的视觉效果，提升了用户的体验。
在一些实施例中，第二电子设备显示第一图标，包括：
若第一电子设备的第一显示界面以投屏窗口的方式显示在第二电子设备的显示界面中，则第二电子设备关闭所述第一显示界面，并显示第一图标；
若第一电子设备的第一显示界面以投屏图标的方式显示在第二电子设备的显示界面中，第二电子设备将投屏图标变为第一图标。
在一些示例中，参见图4，手机的显示界面以投屏窗口320的方式显示在平板的显示界面340中，当平板确定平板或手机的状态发生变化时，关闭该投屏窗口320，并显示拓屏图标330。
在另一个示例中，参见图5，手机的显示界面以投屏图标430的方式显示在平板的显示界面450 中，也就是手机的投屏窗口最小化显示在平板中，当平板确定平板或手机的状态发生变化时，将该投屏图标430变为拓屏图标440。
本申请实施例中，在第二电子设备显示第一图标时，若第一电子设备的显示界面以投屏窗口的方式显示在第二电子设备中，则第二电子设备可以关闭该投屏窗口，并显示第一图标；若第一电子设备的显示界面已经在第二电子设备中最小化显示，则第二电子设备可以将最小化显示的投屏图标变为第一图标。该技术方案可以使得第二电子设备最终显示第一图标，以提醒用户当前属于拓屏模式。

本申请实施例中，当第一电子设备检测到自身的状态从第一状态切换至第二状态时，可以将该状态变化的指示信息发送给第二电子设备。
本申请实施例中，第二电子设备还可以通过接收第一电子设备发送的用于指示第一电子设备的状态发生变化的指示信息，以确定第一电子设备的状态发生变化，从而第二电子设备可以执行切换窗口的策略。

示例性地，当平板检测到用户点击拓屏图标的按钮时，平板可以重新将投屏窗口切换回平板中显示，此时，由于投屏未中断所以无需重新加载投屏数据，进而可以降低延迟。
在一些实施例中，该方法1200还可以包括：
若第二电子设备确定第一显示界面以全屏形式显示在第二电子设备的显示界面中，在第二电子设备确定第二电子设备或第一电子设备从第一状态切换至第二状态时，第二电子设备继续显示第一显示界面。
示例性地，参见图6，当手机的显示界面以全屏形式显示在平板中时，在平板或手机的状态发生变化时，平板中可以继续显示手机的显示界面。
本申请实施例中，当确定第一电子设备或第二电子设备中的一个从普通态变为支架态时，第二电子设备中可以继续显示最大化或全屏的投屏窗口，从而可以避免影响用户的沉浸式体验。
在一些实施例中，第一状态和/或第二状态为电子设备的物理形态。
