具体实施方式
为了更好的理解本申请的技术方案，下面结合附图对本申请实施例进行详细描述。
应当明确，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
在本申请实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请。在本申请实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。
应当理解，本文中使用的术语“和/或”仅仅是一种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这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”或“响应于检测”。类似地，取决于语境，短语“如果确定”或“如果检测(陈述的条件或事件)”可以被解释成为“当确定时”或“响应于确定”或“当检测(陈述的条件或事件)时”或“响应于检测(陈述的条件或事件)”。
图1为本申请实施例提供的无线投屏方法所适用于的应用场景的示意图，如图1所示，图中示意的无线投屏系统包括投屏器、数据源设备和显示设备；其中，投屏器上设置有投屏按键，该投屏按键是实体按键。投屏器上设置了有线通信接口和无线通信接口，有线通信接口比如为图中示意的通用串行总线(Universal Serial Bus，USB)接口，当然不限于此。投屏器通过有线通信接口与数据源设备连接，通过无线通信接口与显示设备无线连接，如此，便提供了无线投屏的无线环境。可以理解的是，显示设备中设置有相应的无线通信接口，以实现与投屏器的无线通信。
其中，数据源设备比如为PC机、笔记本电脑等；显示设备可以是显示屏，电视机等。
实际应用中，需要先建立投屏器与显示设备间的无线通信连接，以便于进行后续的无线投屏处理。在一可选实施例中，可以将显示设备理解为无线相容性认证(Wireless Fidelity，Wi-Fi)路由器，投屏器与数据源设备连接后，可以搜索对应的Wi-Fi信号与之配对连接。
下面在具体介绍本申请实施例提供的无线投屏方法之前，为方便 后续理解，首先结合图2a至图2e，介绍随着用户对投屏器的投屏按键的每次按压操作，显示设备的屏幕显示效果的变化情况。
假设已经将投屏器与数据源设备连接好，当前显示设备已经通电，但是屏幕即显示屏处于图2a所示的屏幕关闭状态。当用户对投屏器的投屏按键按压一次时，投屏器控制显示设备的屏幕显示效果如图2b所示，屏幕中显示初始导航界面即处于初始导航界面显示状态，该初始导航界面中可以包含一个或多个导航图标，比如图中示意的白板、文稿演示、其他等图标，其中，任一图标被点击时，可能直接触发相应的功能，也可能显示其关联的二级菜单。举例来说：白板图标被点击后，触发白板功能的调用，在屏幕上显示出白板功能界面，用户可以在该界面中进行绘图、文字输入等操作；文稿演示图标被点击后，可以弹出如图2b中所示的二级菜单，该二级菜单中比如包括无线投屏、本地文件、U盘等菜单项，其中，每个菜单项可以对应于一种待投屏数据的获取通道。该初始导航界面可以供用户位于显示设备侧时进行相应的控制操作。
当显示设备中显示初始导航界面时，如果此时用户再次按下投屏器的投屏按键，则此时投屏器控制显示设备的屏幕显示效果如图2c所示，此时显示设备将屏幕显示状态切换到无线投屏显示状态，该状态即为数据源设备与显示设备同步显示的状态，亦即数据源设备中显示的待投屏数据传输到显示设备进行同步显示的状态，如图2c中，假设待投屏数据为图中示意的2017年度业务量统计表，则在该无线投屏显示状态下，显示设备的屏幕中显示有该2017年度业务量统计表。
当显示设备处于无线投屏显示状态时，如果此时用户再次按下投屏器的投屏按键，则此时投屏器控制显示设备的屏幕显示效果如图2d所示，此时显示设备将屏幕显示状态再次切换到初始导航界面显示状态。
当显示设备处于图2d所示的初始导航界面显示状态时，如果此时用户再次按下投屏器的投屏按键，则此时投屏器控制显示设备的屏幕显示效果如图2e所示，此时显示设备将屏幕显示状态切换到屏幕关闭 状态。
图2a至图2e示意了一次完成的无线投屏操作过程中显示设备的屏幕显示效果变化情况，可以认为：从图2a到图2c的过程是进入无线投屏的过程，从图2d到图2e是退出无线投屏的过程。
下面将站在投屏器的角度，结合如下的实施例，对投屏器基于用户对投屏按键的按压操作，实现上述显示设备的屏幕显示效果的控制原理进行介绍。
图3为本申请实施例提供的无线投屏方法实施例一的流程示意图，如图3所示，该方法包括以下步骤：
301、响应于对投屏器的投屏按键的按压操作，至少获取显示设备当前的屏幕显示状态。
302、根据获取的屏幕显示状态控制显示设备切换至进入或退出无线投屏的屏幕显示状态。
以投屏器的角度，投屏器对显示设备的屏幕显示状态进行控制需要基于用户当前对投屏器的投屏按键进行按压操作之前，显示设备最近的屏幕显示状态来实现，因此，当投屏器检测到用户对投屏按键进行了按压操作时，首先与显示设备进行通信交互，以至少获得显示设备当前的屏幕显示状态。
其中，之所以说至少需要获得显示设备在该按压操作前最后处于的屏幕显示状态是因为，结合图2a至图2e的屏幕显示效果变化情况，可能会出现不同阶段显示相同界面的情况，此时，则可能还需要获得之前的一个屏幕显示状态，即需要获得按压操作前所处于的两个屏幕显示状态。
实际中，响应于用户对投屏按键的按压操作，投屏器可以向显示设备发送获取请求，以用于获取显示设备当前的屏幕显示状态，从而，显示设备将当前处于的屏幕显示状态反馈至投屏器。
可选地，可以在显示设备侧预先配置每种屏幕显示效果对应的状态标识，比如屏幕关闭状态标识为00，初始导航界面的显示状态标识为01，无线投屏显示状态标识为02。从而，显示设备可以将表征屏幕 显示状态的状态标识反馈至投屏器以告知投屏器显示设备当前的屏幕显示状态。
可选地，显示设备也可以通过截取屏幕的操作，将截取的屏幕图像发送至投屏器，以使投屏器通过识别屏幕图像的特征来确定显示设备当前的屏幕显示状态。比如，如果识别到屏幕图像为黑屏，则认为处于屏幕关闭的屏幕显示状态；如果识别到屏幕图像中具有预设的导航图标，则认为处于初始导航界面的显示状态；如果识别到屏幕图像中具有其他数据内容，则认为处于无线投屏显示状态。
当投屏器获得了一个或两个屏幕显示状态后，便可以结合获取的屏幕显示状态来控制显示设备切换至进入或退出无线投屏的屏幕显示状态，具体地，可以结合获取的屏幕显示状态以及如图2a至图2e所示的屏幕显示状态的变化序列，来确定接下来显示设备应该进入何种屏幕显示状态。
比如：基于前述各种屏幕显示状态的状态标识的举例，图2a至图2e所示的屏幕显示状态的变化序列为：00,01,02,01,00，从而，根据当前获得的屏幕显示状态的状态标识，确定显示设备的屏幕显示状态当前处于哪个序列位置，进而控制显示设备进入下一个屏幕显示状态即可方便地实现对显示设备的控制，此控制过程中，无需用户去往显示设备处进行操作，仅通过按压投屏器的投屏按键即可。
下面结合图4和图5来说明投屏器如何控制显示设备的屏幕显示状态。
图4为本申请实施例提供的无线投屏方法实施例二的流程示意图，如图4所示，该方法包括以下步骤：
401、响应于对投屏器的投屏按键的按压操作，获取显示设备当前的第一屏幕显示状态。
402、若第一屏幕显示状态为初始导航界面显示状态，则获取第一屏幕显示状态之前的第二屏幕显示状态。
如前述实施例中所举例的屏幕显示状态的变化序列：00,01,02,01,00，如果用户按压投屏按键时，显示设备处于初始导航界 面显示状态01，则由于该变化序列中存在两个序列位置为01，因此，仅基于该初始导航界面显示状态无法判定接下来应该控制显示设备进入何种屏幕显示状态。因此，此时还需要获得之前的第二屏幕显示状态，以便结合第一屏幕显示状态盒第二屏幕显示状态控制显示设备进行屏幕显示状态的切换。
403、若第二屏幕显示状态为屏幕关闭状态，则控制显示设备切换到无线投屏显示状态，以及，控制数据源设备采集待投屏数据并将从数据源设备接收到的待投屏数据传输至显示设备进行显示。
404、若第二屏幕显示状态为无线投屏显示状态，则控制显示设备切换到屏幕关闭状态。
如上述变化序列可知，初始导航界面显示状态01之前的第二屏幕显示状态可能是屏幕关闭状态00，也可能是无线投屏显示状态02。
当第二屏幕显示状态为屏幕关闭状态00时，说明用户此时按压投屏按键是需要进入无线投屏显示状态，以进行数据源设备向显示设备的无线投屏，此时，投屏器可以向显示设备发送切换控制命令，以控制显示设备切换到无线投屏显示状态，另外，此时，投屏器还需要向数据源设备发送指示信号，以控制数据源设备采集待投屏数据，数据源设备将采集的待投屏数据发送至投屏器，投屏器将从数据源设备接收到的待投屏数据传输至显示设备进行显示，即显示在当前显示设备的屏幕界面中。
值得说明的是，数据源设备采集待投屏数据的过程，以及可能对待投屏数据进行的压缩、编码等过程，可以采用现有技术实现，本申请实施例不赘述。
当第二屏幕显示状态为无线投屏显示状态02时，说明用户此时按压投屏按键是想要关闭显示设备屏幕，即最终退出无线投屏功能，此时，投屏器向显示设备发送切换控制命令，以控制显示设备切换到屏幕关闭状态。
图5为本申请实施例提供的无线投屏方法实施例三的流程示意图，如图5所示，该方法包括以下步骤：
501、响应于对投屏器的投屏按键的按压操作，获取显示设备当前的第一屏幕显示状态。
502、若第一屏幕显示状态为无线投屏显示状态，则控制显示设备切换到初始导航界面显示状态，以及控制数据源设备停止采集待投屏数据。
若按下投屏按键时，显示设备处于无线投屏显示状态02，说明用户准备退出无线投屏功能，但是此时用户可能还需要进行其他的操作，比如调用白板功能等，因此，如前述变化序列，接下来应该控制显示设备切换到初始导航界面显示状态01，使得在显示设备的屏幕中显示出初始导航界面。另外，退出无线投屏功能，则数据源设备也不再需要采集待投屏数据，因此，投屏器此时需要向数据源设备发送指示信号，以控制数据源设备停止采集待投屏数据。
503、若第一屏幕显示状态为屏幕关闭状态，则控制显示设备切换到初始导航界面显示状态。
若按下投屏按键时，显示设备处于屏幕关闭状态00，说明用户此时需要开启屏幕以便进行后续的无线投屏功能的触发或者其他功能的触发，因此，如前述变化序列，接下来应该控制显示设备切换到初始导航界面显示状态01，使得在显示设备的屏幕中显示出初始导航界面。
值得说明的是，在一可选实施例中，如图2b中所示，初始导航界面中可以包括触发无线投屏功能的按钮，当用户位于显示设备侧时，用户也可以在该初始导航界面中点击该按钮来触发无线投屏功能，此时，当显示设备检测到用户对该按钮进行了点击操作时，可以向投屏器发送无线投屏开启通知，投屏器根据接收到的该无线投屏开启通知，控制数据源设备采集待投屏数据并将从数据源设备接收到的待投屏数据传输至显示设备进行显示，以实现待投屏数据向显示设备的无线投屏显示。
综上，本申请实施例提供了使用户仅需要通过操作投屏器的投屏按键即可实现对无线投屏过程的控制的方案。具体地，每当用户对投屏器的投屏按键触发按压操作时，投屏器通过至少获取显示设备当前 的屏幕显示状态可知当前处于整个无线投屏过程的什么阶段，从而基于获取的屏幕显示状态控制显示设备切换至下一阶段所对应的屏幕显示状态即进入或退出无线投屏的屏幕显示状态，从而仅通过操作投屏器的投屏按键即可方便地实现了对显示设备侧的无线投屏控制。
