具体实施方式
以下结合附图对本公开的示范性实施例做出说明，其中包括本公开实施例的各种细节以助于理解，应当将它们认为仅仅是示范性的。因此，本领域普通技术人员应当认识到，可以对这里描述的实施例做出各种改变和修改，而不会背离本公开的范围和精神。 同样，为了清楚和简明，以下的描述中省略了对公知功能和结构的描述。
以下将结合图1对本公开提供的传输画面数据的方法和装置的示例性系统架构进行描述。
图1示意性示出了根据本公开实施例的可以应用传输画面数据的方法和装置的示例性系统架构100。需要注意的是，图1所示仅为可以应用本公开实施例的系统架构的示例，以帮助本领域技术人员理解本公开的技术内容，但并不意味着本公开实施例不可以用于其他设备、系统、环境或场景。
如图1所示，根据该实施例的系统架构100可以包括投屏设备110和终端设备120。其中，投屏设备110包括显示屏111，用于显示输入投屏设备110的画面数据。移动终端121包括显示屏121，用于显示本地显示界面。
投屏设备110可以是具有显示屏，且支持与其他终端进行通讯的各种电子设备，例如车机设备、智能电视、膝上型便携计算机和台式计算机等等。终端设备120可以是具有显示屏，并且支持与其他终端进行通讯的各种电子设备，包括但不限于智能手机、平板电脑、膝上型便携计算机和台式计算机等等。投屏设备110与终端设备120上可以安装有各种通讯客户端应用，例如车联网应用、网页浏览器应用、搜索类应用、即时通信工具等。
终端设备120与投屏设备110之间可以建立有线或无线的连接。其中，有线连接例如可以包括USB(Universal Serial Bus，通用串行总线)连接、HDMI(High Definition Multimedia Interface，高清多媒体接口)连接等，无线连接例如可以包括WLAN(Wireless Local Area Network，无线局域网)连接、NFC(Near Field Communication，近场通讯)连接、蓝牙连接等。终端设备120与投屏设备110可以通过彼此之间的连接实现交互，例如终端设备120可以将显示屏121中显示的界面的图像通过连接发送至投屏设备110，投屏设备110在接收到来自终端设备120的图像后，可以在投屏设备110的显示屏111中显示该图像，以实现投屏。
本领域技术人员可以理解，图1中的终端设备和投屏设备的数目仅仅是示意性的。根据实现需要，可以具有任意数目的终端设备和投屏设备。
下面结合图2对根据本公开实施例的传输画面数据的方法做进一步说明。
图2示意性示出了根据本公开的实施例的传输画面数据的方法的流程图。
如图2所示，该传输画面数据的方法200包括操作S210～S240。该方法200例如可 以由上文所示的终端设备执行。
其中，在操作S210，获取本地显示界面的本地显示比例和投屏设备的屏幕比例。
根据本公开的实施例，本地显示界面例如可以为终端设备中显示的界面，包括但不限于操作系统界面、应用程序界面等等。本地显示比例可以根据本地显示界面的宽和高来确定。投屏设备的屏幕比例可以根据投屏设备的屏幕(例如上文所示的显示屏)的宽和高来确定。
然后，在操作S220，将本地显示比例和投屏设备的屏幕比例与比例阈值进行比较。
根据本公开的实施例，比例阈值可以根据实际需要来预先确定。示例性地，本实施例中，比例阈值可以设置为1。
在操作S230，在本地显示比例大于比例阈值且屏幕比例小于比例阈值，或者本地显示比例小于比例阈值且屏幕比例大于比例阈值的情况下，通过悬浮窗控件更改显示模式。
根据本公开的实施例，若本地显示比例大于比例阈值且屏幕比例小于比例阈值，或者本地显示比例小于比例阈值且屏幕比例大于比例阈值，则表示本地显示比例与屏幕比例不匹配，因此通过悬浮窗控件更改显示模式以使本地显示比例与屏幕比例匹配。
根据本公开的实施例，若本地显示比例和屏幕比例均小于比例阈值，或者本地显示比例和屏幕比例均大于比例阈值，又或者本地显示比例和屏幕比例均等于比例阈值，则表示本地显示比例与屏幕比例匹配，则维持当前的显示模式，不执行更改显示模式的操作。
在操作S240，将与更改显示模式后的本地显示界面对应的画面数据传输至投屏设备，以通过投屏设备展示画面数据。
对于具有不同的屏幕比例的终端设备和投屏设备，在投屏时，终端设备会将与投屏设备屏幕比例不匹配的画面数据投射到投屏设备的屏幕上显示，从而会造成投屏设备屏幕中显示的画面过小、画面缺失等问题。
根据本公开的实施例，根据本地显示比例和投屏设备的屏幕比例，更改显示模式，从而可以向投屏设备传输与其屏幕比例匹配的画面数据，提高了投屏的效果。
下面结合图3对根据本公开实施例的通过悬浮窗控件更改显示模式的方法做进一步说明。
图3示意性示出了根据本公开的实施例的通过悬浮窗控件更改显示模式的方法的流 程图。
如图3所示，该通过悬浮窗控件更改显示模式的方法330包括操作S331～S334。
在操作S331，获取当前的显示模式。
根据本公开的实施例，显示模式例如可以包括横屏模式和竖屏模式。其中，横屏模式是指适应于设备横向放置时的显示模式。竖屏模式是指适应于设备竖直放置时的显示模式。
在操作S332，判断当前的显示模式是否为横屏模式。在当前的显示模式为横屏模式的情况下，执行操作S333。在当前的显示模式为竖屏模式的情况下，执行操作S334。
在操作S333，通过悬浮窗控件将显示模式设置为竖屏模式。
在操作S334，通过悬浮窗控件将显示模式设置为横屏模式。
根据本公开的实施例，可以通过悬浮窗控件调用系统应用程序接口(API)来将显示模式设置为竖屏模式或横屏模式。示例性地，本实施例中，系统应用程序接口例如可以包括setRequestedOrientation。
根据本公开的实施例，通过利用悬浮窗控件调用系统应用程序接口来设置显示模式，对于各种应用程序均有效，兼容性较好。
例如，在某些场景下，应用程序会锁定显示模式，保持横屏显示或竖屏显示，相关技术更改显示模式时，无法对锁定显示模式的应用程序生效。
根据本公开的实施例，通过创建并悬浮窗控件，并利用该悬浮窗控件调用系统层面的API更改显示模式，是符合系统规范的，因此，可以适用于锁定显示模式的应用程序。
图4示意性示出了根据本公开另一实施例的传输画面数据的方法的流程图。
如图4所示，该传输画面数据的方法400包括操作S410～S450。
在操作S410，在本地显示界面中创建悬浮窗控件，并隐藏悬浮窗控件。
根据本公开的实施例，以Android系统为例，Android系统中，应用程序的每个页面包含PhoneWindow(手机窗口)，该PhoneWindow是应用层的对象，是切换显示模式的关键。本实施例中，悬浮窗控件可以基于PhoneWindow。基于此，可以通过悬浮窗控件可以请求Android系统底层的WindowManagerService(窗口管理服务)实现全局的显示模式变更。
根据本公开的实施例，可以将悬浮窗控件的颜色配置为透明以及/或者将悬浮窗控件的尺寸配置为小于尺寸阈值，来隐藏悬浮窗控件。
然后，在操作S420，获取本地显示界面的本地显示比例和投屏设备的屏幕比例。
在操作S430，将本地显示比例和投屏设备的屏幕比例与比例阈值进行比较。
在操作S440，在本地显示比例大于比例阈值且屏幕比例小于比例阈值，或者本地显示比例小于比例阈值且屏幕比例大于比例阈值的情况下，通过悬浮窗控件更改显示模式。
在操作S450，将与更改显示模式后的本地显示界面对应的画面数据传输至投屏设备，以通过投屏设备展示画面数据。
根据本公开的实施例，操作S420～S450例如可以参考上文所示内容，在此不再赘述。
根据本公开的实施例，通过创建并隐藏悬浮窗控件，并利用该隐藏的悬浮窗控件更改显示模式，可以实现无感知地更改显示模式，从而提高用户体验。
图5示意性示出了根据本公开另一实施例的传输画面数据的方法的流程图。
如图5所示，该传输画面数据的方法500包括操作S510～S5110。
在操作S510，建立与投屏设备的之间的连接。
根据本公开的实施例，该连接可以是有线连接也可以是无线连接。其中，有线连接例如可以包括USB连接、HDMI连接等，无线连接例如可以包括WLAN连接、NFC连接、蓝牙连接等。
在操作S520，通过连接获取投屏设备的屏幕的宽和高。
在操作S530，根据屏幕的宽和高，计算投屏设备的屏幕比例。
根据本公开的实施例，例如可以根据以下公式计算投屏设备的屏幕比例：
ratio1＝width1/height1
其中，ratio1为投屏设备的屏幕比例，width1为投屏设备的屏幕的宽，height1为投屏设备的屏幕的高。
在操作S540，获取本地显示界面的宽和高。
在操作S550，根据本地显示界面的宽和高，计算本地显示比例。
根据本公开的实施例，例如可以根据以下公式计算本地显示界面的本地显示比例：
ratio2＝width2/height2
其中，ratio2为本地显示比例，width2为本地显示界面的宽，height2为本地显示界面的高。
根据本公开的实施例，可以先执行操作S520～S530再执行操作S540～S550，也可以 先执行操作S540～S550再执行操作S520～S530，还可以使操作S520～S530和操作S540～S550可以同时执行。本公开对操作S520～S530和操作S540～S550之间的执行顺序不作具体限定。
然后，根据以下操作将本地显示比例和投屏设备的屏幕比例与比例阈值进行比较。
其中，在操作S560，确定屏幕比例是否大于比例阈值。在屏幕比例大于比例阈值的情况下，执行操作S570。在屏幕比例小于或等于比例阈值的情况下，执行操作S580。
在操作S570，确定本地显示比例是否大于比例阈值。在本地显示比例大于比例阈值的情况下，执行操作S5110。在本地显示比例小于或等于比例阈值的情况下，执行操作S590。
根据本公开的实施例，对于显示界面的宽和高不同的设备，若本地显示比例大于比例阈值，则可以确定设备当前的显示模式为竖屏模式。若本地显示比例小于比例阈值，则可以确定设备当前的显示模式为横屏模式。
根据本公开的另一些实施例，对于显示界面的宽和高相同的设备，可以读取系统信息来获取当前的显示模式，并进行相应的更改。
在操作S580，确定本地显示比例是否大于比例阈值。在本地显示比例大于比例阈值的情况下，执行操作S5100。在本地显示比例小于比例阈值的情况下，执行操作S5110。
在操作S590，通过悬浮窗控件将显示模式设置为横屏模式。然后执行操作S5110。
在操作S5100，通过悬浮窗控件将显示模式设置为竖屏模式。然后执行操作S5110。
在操作S5110，将本地显示界面对应的画面数据通过连接传输至投屏设备，以通过投屏设备展示画面数据。
下面参考图6，结合具体实施例对上文所示的传输画面数据的方法做进一步说明。本领域技术人员可以理解，以下示例实施例仅用于理解本公开，本公开并不局限于此。
示例性地，本实施例中，终端设备可以为智能手机(以下简称手机端)，投屏设备可以为车机设备(以下简称车机端)。其中，手机端显示的本地显示界面的分辨率为720*1280像素，车机端的屏幕的分辨率为1280*720像素。另外，本实施例中，比例阈值为1。
图6示意性示出了根据本公开另一实施例的传输画面数据的方法的示意图。
如图6所示，在操作S610，车机端与手机端建立连接，以实现车机端与手机端之间的互联。
在操作S620，手机端向车机端发送画面数据。
在操作S630，车机端展示手机传来的画面数据。
在操作S640，手机端创建悬浮窗控件。
在操作S650，车机端将车机屏幕的分辨率同步至手机端。
在操作S660，手机端根据分辨率得到车机端屏幕的宽为1280像素，高为720像素，从而计算车机端的屏幕比例为1280∶720＝16∶9，即该屏幕比例的比值大于比例阈值1。另外，手机端计算本地显示界面的本地显示比例为720∶1280＝9∶16，即该本地显示比例的比值小于比例阈值1。从而可以确定车机端的屏幕比例与手机端本地显示比例不匹配。
在操作S670，手机端通过悬浮窗控件调用系统API以切换屏幕的显示模式。
然后，在操作S680，手机端传输切换显示模式后的本地显示界面的画面数据至车机端，从而使画面数据与车机屏幕的屏幕比例匹配。
在操作S690，车机端在屏幕中显示更改显示模式后的画面数据。
把手机端比例为16∶9的画面数据，展示在车机端比例为9∶16的屏幕上时，相关技术将画面数据在车机端的屏幕中居中缩小显示，造成车机端屏幕的空间浪费，并且导致画面过小、难以看清楚。虽然可以由用户在手机端进行操作来更改显示模式，但是步骤较为繁琐。另外，在驾驶车辆的场景中，用户对手机端进行操作是非常危险的。
根据本公开的实施例的传输画面数据的方法可以实现自动更改显示模式，使得手机端输出至车机端的画面数据可以匹配车机端的屏幕比例，从而使车机端显示的画面更为清晰。另外，更改显示模式的过程不需要用户进行繁琐的操作，更为方便。
