具体实施方式
下面将结合附图，对本申请实施例中的技术方案进行描述。
本申请实施例提供的输入设备的事件处理方法可应用于电子设备中。例如，该电子设备可以为平板电脑、笔记本电脑、可穿戴设备、多媒体播放设备、电子书阅读器、个人计算机(personal computer，PC)、个人数字助理(personal digital assistant，PDA)、上网本、增强显示(augmented reality，AR)设备、虚拟现实(virtual reality，VR)设备、智能手机、智能电视、智慧屏设备、智能相机、便携式多媒体播放器(portable multimedia player，PMP)、投影设备、混合现实(mixed reality，MR)设备、电视机或人机交互场景中的体感游戏机等电子设备。本申请对电子设备的具体形式不作限制。
电子设备通常可以与一个或多个输入设备(如输入外设)连接，以实现相应功能。可以理解，输入设备可以是无线外设，也可以是有线外设，对此不作具体限定。
示例性地，无线外设是指基于无线传输协议(如蓝牙协议或者2.4G通信协议等)实现向终端设备输入的输入设备。在本申请实施例中，输入设备所支持的输入方式可以包括但不限于按键方式(如鼠标、键盘等)、滚动滚轮方式(如鼠标等)、手势输入方式、肢体语言输入方式、语音输入方式、表情输入方式、眼部活动输入方式等。
进一步的，本申请实施例也不限定输入设备与电子设备之间的具体通信方式。以输入设备是蓝牙外设为例，蓝牙外设可以基于支持设备间多连接协议栈的蓝牙协议与电子设备通信，以实现多电子设备共享输入设备。
例如，个人计算机PC可以与鼠标连接，通过鼠标实现PC显示屏上光标的移动，以及进一步的文件的打开/删除等功能。PC也可以与键盘连接，通过键盘实现移动PC显示屏上的光标、输入字符、打开/删除文件等功能。又如，平板电脑可以与键盘连接，通过键盘实现向平板电脑输入字符、打开平板电脑中的应用/视频/音频等功能。
本申请实施例提供的输入设备的事件处理方法可应用于跨操作系统的多设备协同场景中。示例性地，跨操作系统的多设备协同场景包括：PC(运行有Windows操作系统)，平板(运行有安卓系统)，其中，PC与平板之间建立有通信连接。假设当前焦点设备为平板，由于操作系统不同，当PC的输入外设使用快捷键进行操作时，平板无法识别快捷键事件，也就无法对快捷键事件进行响应，极大影响了操作效率，用户体验不好。
示例性地，焦点设备是指与输入设备建立通信连接，且输入设备当前所能直接操控的电子设备；非焦点设备是指与输入设备建立通信连接，但是输入设备当前不能直接操控的电子设备。以输入设备是无线鼠标且该无线鼠标由PC和平板共享为例，在无线鼠标移动到PC后，焦点设备是PC；在无线鼠标移动到平板后，焦点设备是平板。
为便于理解，以下结合1描述本申请实施例的应用场景。
参考图1，图1示出了本申请实施例的应用场景的示例图。如图1所示，PC和平板建立无线通信连接。当PC和平板建立通信连接后，鼠标可以在PC和平板两端自由移动。当焦点在平板时，平板可以通过鼠标和键盘进行输入。但是由于PC和平板采用不同的操作系统，因此，当用户对PC的鼠标和/或键盘执行快捷键操作时，平板无法对快捷键操作响应。即快 捷键在此场景下无法发挥功能，从而影响用户的操作效率。
应理解，本申请实施例对PC和平板的连接方式不作具体限定。PC和平板可以通过蓝牙连接、无线局域网连接、红外连接等。
为了提高用户在跨操作系统下的设备操作体验，本申请实施例拟提出一种输入设备的事件处理方法，通过将输入设备的快捷键事件从第一操作系统转换为第二操作系统可以识别的事件信息，能够实现输入设备的快捷键事件在不同操作系统间的自动转换，从而实现快捷键在不同操作系统间生效。

以下结合图5至图8描述本申请实施例的输入设备的事件处理方法。
图5是本申请实施例的输入设备的事件处理方法500的示意性流程图。可以理解，图5的方法可应用到图1所示的场景中。比如，图5中的第一电子设备是图1中的PC，第二电子设备是图1中的平板。如图5所示，所述方法500包括：
步骤501，第一电子设备检测到所述第一输入设备或所述第二输入设备的第一事件，所述第一事件是所述第一操作系统下的事件，所述第一电子设备与第一输入设备处于连接状态，所述第一电子设备与第二输入设备处于连接状态。
第一事件用于泛指在第一操作系统下第一电子设备监听到的输入设备的输入事件。输入事件包括快捷键事件。快捷键事件是指通过按下输入设备的快捷键触发的事件，比如，按下Windows+L快捷键可触发锁屏事件。
可选地，第一事件可以是第一输入设备和第二输入设备共同触发的事件，比如，键盘按键加鼠标滚轮的操作；也可以是第一输入设备或第二输入设备单独触发的事件，比如，滑动鼠标滚轮事件。
示例性地，第一输入设备为无线鼠标，第二输入设备是键盘。第一电子设备连接有无线鼠标和键盘。
此处作统一说明，第一电子设备与第二电子设备为不同操作系统的电子设备。第一电子设备与第二电子设备建立有通信连接。比如，第一电子设备为PC，采用Windows系统；第二电子设备为平板电脑，采用安卓系统。
本申请实施例对第一电子设备与第二电子设备的通信连接方式不作具体限定。比如，第一电子设备与第二电子设备通过蓝牙连接。
示例性地，第一电子设备在监听各种外接设备(比如，键盘或鼠标等外设)的输入事件时，检测到第一输入设备或第二输入设备的事件，比如第一事件。第一事件可以理解为第一操作系统下的事件。为了实现第一事件能够在第二电子设备中执行，本申请实施例需要将第一事件转换为第二操作系统下的事件。
步骤502，第一电子设备确定所述第一输入设备当前的焦点设备。
在监听到第一事件后，可以先判断当前的焦点设备是第一电子设备还是第二电子设备。如果判断出焦点设备是第一电子设备，则执行步骤503-2；如果判断出焦点设备是第二电子设备，则执行步骤503-1。
焦点设备的描述可以参考前文，为了简洁，此处不再赘述。
本申请实施例对如何判断焦点设备的方式不作具体限定。
可选地，作为一种实施方式，当第一输入设备是无线鼠标时，确定第一输入设备当前的焦点设备包括：
确定所述无线鼠标的光标在所述第一电子设备的显示屏上的位置；
在所述无线鼠标的光标从所述第一电子设备的显示屏移动到所述第二电子设备的显示屏时，焦点设备是所述第二电子设备；
在所述无线鼠标的光标位于所述第一电子设备的显示屏，且没有滑出第一电子设备的显示屏的趋势时，焦点设备是所述第一电子设备。
示例性地，假设第一电子设备位于第二电子设备的右侧，当检测到无线鼠标的光标从第一电子设备的显示屏的右边缘移动到第二电子设备时，则确定焦点设备为第二电子 设备；当检测到无线鼠标的光标未超出第一电子设备的显示屏的右边缘时，则确定焦点设备为第一电子设备。
示例性地，第一设备检测到无线鼠标滑出第一电子设备显示屏的边缘，且无线鼠标滑向第二电子设备的移动坐标超过预设阈值，则确定焦点设备为第二电子设备。
应理解，上述确定焦点设备的方式只是示例性描述，并非要将本申请实施例限定到上述示例中。事实上，本领域技术人员可以采用其他方式判断焦点设备。比如，采用屏幕光标边缘检测算法进行检测。
步骤503-1，在焦点设备是第二电子设备时，第一电子设备基于第一事件的事件类型以及第一映射关系生成事件信息，所述事件信息包括按键扫描码和第一事件类型，所述第一映射关系包括所述第一按键扫描码和第一按键码的对应关系，所述按键扫描码是所述第一事件在所述第二操作系统下对应的按键码，所述第一按键码是所述第一事件在第一操作系统下的按键码。所述第一事件类型标识用于标识第一事件的事件类型。
第一映射关系中可以包括第一事件的按键码在不同操作系统下的对应关系。
举例来说，以下表1是锁屏事件在Windows系统下的按键码以及锁屏事件在Android系统下的按键扫描码的映射关系。
表1
在上述表1中，对于锁屏事件而言，Windows系统下的按键码为0x5B，0x4C，对应的Android系统下的按键扫描码为125，38。
应理解，上述表1只是以锁屏事件为例进行描述，本申请实施例并不限于此。事实上，对于其他的快捷键事件，也存在按键码映射关系，此处不再一一列举。
示例性地，对应按键26个英文字母的按键，在Android系统下具有相应的按键扫描码。比如，字母A在Android系统下的按键扫描码为30；字母B在Android系统下的按键扫描码为48；字母C在Android系统下的按键扫描码为46；…；字母X在Android系统下的按键扫描码为45；字母Y在Android系统下的按键扫描码为21；字母Z在Android系统下的按键扫描码为44。应理解，为了简洁，此处只是示例性给出部分字母在Android系统下的按键扫描码。
应理解，上述关于26个英文字母的按键在Windows系统下也具有相应的按键码。比如，26个英文字母的按键可转换为十六进制数表征，即得到26个英文字母在Windows系统下的按键码。这样，26个英文字母的按键码映射关系包括：字母在Windows系统下的按键码以及该字母在Android系统下对应的按键扫描码。
以下结合表2描述另一按键码映射关系。例如，表2中示出了键盘中的部分按键在Windows系统下对应的按键码，以及在Android系统下对应的按键扫描码的映射表。
表2

在表2中，以Windows键为例，在Windows系统下对应的按键码为0x5B，在Android系统下对应的按键扫描码为125。
应理解，上述表2只是键盘中的部分按键为例进行描述，本申请实施例并不限于此。事实上，对于其他的按键，也存在在Windows系统的按键码和Android系统下的按键扫描码映射关系，此处不再一一列举。
还应理解，上述关于按键码和按键扫描码的映射关系只是示例性描述，本领域技术人员可以根据需求或者按照不同操作系统的规范，新增按键码映射关系。
示例性地，第一电子设备中可维护不同操作下输入设备(比如键盘鼠标等外设)的映射关系。当第一电子设备监听到输入设备触发的事件后，可在映射关系中进行查询，获得事件在Android系统下的按键扫描码。在获得按键码后，第一电子设备可以将按键扫描码以及事件类型封装成数据(比如事件信息)传输给第二电子设备。
可选地，事件类型可通过事件ID进行标识。例如，在封装过程中，可将事件ID以及按键扫描码进行封装，发送给第二电子设备。
以下结合表3描述事件类型与事件ID的定义表。例如，表3中示出了部分事件类型以及对应的事件ID。
表3
在表3中，键盘Down即用户按下键盘且未松手的事件，比如，键盘Down事件可以通过GENERIC_INPUT_TYPE_KEY_DOWN标识。键盘Up即用户按下键盘后松手的事件，比如，键盘Up事件可以通过GENERIC_INPUT_TYPE_KEY_UP标识。滚轮垂直移动事件即用户滑动鼠标滚轮进行垂直移动的事件，比如，滚轮垂直移动事件可以通过GENERIC_INPUT_TYPE_VERTICAL_WHEEL标识。滚轮水平移动事件即用户滑动鼠标滚轮进行水平移动的事件，比如，滚轮水平移动事件可以通过GENERIC_INPUT_TYPE_HORIZONTAL_WHEEL标识。
应理解，上述表3中示出的事件类型以及相应的事件ID仅是示例性描述，本申请实施例并不限于此。
还应理解，上述关于事件类型与对应的事件ID只是示例性描述，本领域技术人员可以根据需求，新增事件类型与对应的事件ID。
示例性地，锁屏事件是通过两个锁屏快捷键实现的，比如Windows键和L键组合键。当用户按下Windows键后，第一电子设备通过第一映射关系查询到Windows键在Android系统下对应的按键扫描码(125)，然后会将键盘Down事件以及Windows键在Android系统下对应的按键扫描码(125)发送给第二电子设备；接着，当用户按下L键后，再向第二电子设备发送“L键在Android系统下对应的按键扫描码(38)”以及L键的“键盘Down”事件；当用户松开L键后，第一电子设备会向第二电子设备发送“L键在Android系统下对应的按键扫描码(38)”以及L键的“键盘UP”事件；当用户松开Windows键后，再向第二电子设备发送键盘UP事件以及Windows键在Android系统下对应的按键扫描码(125)。
可选地，步骤503-2，在焦点设备是所述第一电子设备时，在所述第一电子设备中执行所述第一事件。
示例性地，在检测到鼠标未移动到第一电子设备的边缘时(比如右边缘)，可以将第一事件在第一电子设备中进行处理。可选地，将第一事件在第一电子设备中进行处理，包括：采用第一电子设备中的原有事件流程对第一事件进行响应处理。比如，将第一事件分发到第一电子设备的其他窗体(或者说窗口)进行处理。
步骤504，第一电子设备向第二电子设备发送事件信息，所述事件信息用于所述第二电子设备生成所述第二操作系统下的事件。相应的，第二电子设备接收来自第一电子设备的所述事件信息。
本申请实施例对第一电子设备向第二电子设备发送事件信息时采用的传输格式不作具体限定。
示例性地，第一电子设备基于第一传输格式(比如表3中示出的格式)将所述事件信息发送给所述第二电子设备，所述第一传输格式是所述第一电子设备与所述第二电子设备预先定义的按键事件传输格式。
需要说明的是，第一传输格式是第一电子设备与第二电子设备提前约定好的传输格式。第二电子设备在接收到以上述第一传输格式发送的事件信息后，可按照第一传输格式进行解析。因此，通过预定的传输格式进行事件信息的发送，能够保证对端(即第二电子设备)可以解析出该事件信息。
应理解，“第一传输格式”用于泛指第一电子设备向第二电子设备发送事件信息的传输格式，本申请实施例对其命名不作具体限定。比如，“第一传输格式”也可以称作“按键事件传输格式”等。
示例性以下结合描述按键事件传输格式。例如，表4中示出了按键事件传输格式的示例：
表4

上述表4中示出了各个字段对应的字节数。基于上述表4示出的传输格式，可以对按键码以及时间类型进行封装，获得事件信息。
应理解，表4中的传输格式仅是示例性描述，本申请实施例并不限于此。事实上，本领域技术人员也可以采用其他传输协议或传输格式传输上述事件信息。
步骤505，第二电子设备根据所述事件信息获取所述按键扫描码和所述第一事件类型(可以通过事件ID进行标识)。
示例性地，如果第一电子设备基于第一传输格式发送上述事件信息，相应的，第二电子设备在收到所述事件信息后，基于第一传输格式对事件信息进行解析，获得所述按键扫描码和所述第一事件类型(比如，获得事件ID)。
第二电子设备可以将解析得到的按键扫描码和所述第一事件类型直接注入到input驱动中，也可以基于解析得到的按键扫描码和所述第一事件类型进行映射，将映射后的事件类型注入到input驱动中。
可选地，作为一个实施例，第二电子设备(或者说第二电子设备的数据接收模块)在通过解析得到事件类型后，可以将解析得到的事件类型作进一步映射，比如，将第一事件类型映射为第二事件类型，以便使得事件类型更符合第二操作系统下的使用规范或标准，避免当第二操作系统下无法支持第一事件类型时无法对第一事件类型作出响应，有助于提升用户的操作体验。可选地，第二电子设备将映射后的第二事件类型注入到input驱动中。比如，第二电子设备解析出快捷键事件包括：按下“Windows+左方向键(即向左箭头键)”，“Windows+左方向键”在Windows系统下为“将窗口最大化到屏幕左侧的事件”，但是安卓系统下没有相应的事件类型，那么第二电子设备将此事件映射为“Windows+左方向键”映射为“返回”事件，并将“返回”事件注入到input驱动中。
应理解，本申请实施例对第二电子设备将解析后的事件如何做映射不作具体限定。本领域技术人员可以基于实际需求进行相应的映射。
步骤506，第二电子设备基于按键扫描码和第一事件类型(通过第一事件类型ID进行标识)调用接口进行响应。
示例性地，步骤506，包括：506-1，第二电子设备的数据接收模块将按键扫描码和第一事件类型注入到input驱动中；506-2，input驱动将按键扫描码和第一事件类型上报到input模块；步骤506-3，input模块根据按键扫描码和第一事件类型调用接口进行响应。示例性地，input模块可以将按键扫描码转换为安卓系统下的按键码。
示例性地，第二电子设备中的input模块根据按键扫描码和第一事件类型，调用相应的功能接口，或者，将快捷事件分发给应用。后续将结合示例进行描述。
在本申请实施例中，第一电子设备在监听到输入设备的快捷键事件(比如第一事件)后，如果判断出焦点设备为第二电子设备，那么第一电子设备通过将输入设备的快捷键事件从第一操作系统转换为第二操作系统可以识别的事件信息，并将事件信息发送给第二电子设备，以便第二电子设备对事件信息作出响应，能够实现输入设备的快捷键事件在不同操作系统间的自动转换，从而实现快捷键在不同操作系统间生效，提升了操作效 率，极大提高用户的操作体验。
可选地，作为一个实施例，基于按键扫描码和第一事件类型调用接口进行响应包括：调用系统接口对所述按键扫描码和所述第一事件类型进行响应处理。
示例性地，所述按键扫描码为锁屏事件快捷键对应的键码，所述第一事件类型为按下按键类型；所述调用系统接口对所述按键扫描码和所述第一事件类型进行响应处理包括：
调用锁屏接口对所述电子设备的显示屏进行锁屏。
比如，安卓系统下有对应的锁屏接口，此时无需将事件信息分发到应用。
可选地，如果第二电子设备对按键扫描码和/或第一事件类型进行了映射，那么此处可以调用系统接口对映射后的按键码(比如第三按键码)和映射后的事件类型(比如第二事件类型)进行响应处理。
为便于理解，以下结合图6中的示例进行说明。在一种可能的实现方式中，以第一电子设备是PC，第二电子设备是平板为例，PC和平板共享鼠标为例，如图6所示，PC和平板处于连接态。在图6中，鼠标光标在平板中，即当前焦点设备为平板。用户可通过按下锁屏快捷键(包括Windows键和L键)触发锁屏事件。PC在检测到锁屏事件后，将该锁屏事件转换为平板下的按键码和事件类型。如图6所示，当用户按下Windows键和L键后，平板调用系统接口实现锁屏，即平板熄屏。从图6中可知，平板对锁屏快捷键事件作出了响应。
可选地，作为一个实施例，基于按键扫描码和第一事件类型调用接口进行响应包括：包括：利用事件分发机制将所述按键扫描码和所述第一事件类型发送到应用程序进行响应处理。
示例性地，所述按键扫描码包括复制文本事件的相关快捷键(比如复制快捷键中的ctrl键)的按键码，所述第一事件类型为按下按键类型(比如按下ctrl键)；利用事件分发机制将所述按键扫描码和所述第一事件类型发送到应用程序进行响应处理包括：将所述按键扫描码和所述第一事件类型发送到第一应用程序进行响应处理，所述第一应用程序支持所述复制文本事件，所述第一应用程序是所述电子设备正在运行的应用程序。
可选地，如果第二电子设备对按键扫描码和/或第一事件类型进行了映射，那么可以利用事件分发机制对映射后的按键扫描码和映射后的事件类型进行响应处理。
为便于理解，以下结合图7中的示例进行说明。在一种可能的实现方式中，以第一电子设备是PC，第二电子设备是平板，PC和平板共享鼠标为例，如图7所示，PC和平板处于连接态。在图7中，鼠标光标在平板中，即当前焦点设备为平板。用户可通过按下全选文本快捷键(包括ctrl键和A键)触发全选文本事件。PC在检测到全选文本事件后，将该全选文本事件转换为平板下的按键码和事件类型。如图7所示，当用户按下ctrl键和A键后，平板将全选文本事件分发到应用。假设平板当前正在运行某个文本类应用，那么调用该文本类应用的接口实现全选文本事件，比如选中平板正在显示的文本“荣耀新品发布…”。从图7中可知，平板对全选文本事件快捷键事件作出了响应。
应理解，图7中的示例仅是以“全选文本快捷键事件”为例进行举例，本申请实施例并不限于此。
应理解，图6和图7中示出的例子是关于键盘的快捷键操作，本申请实施例并不限于此。事实上，用户也可以通过键盘和鼠标的共同实现某些快捷键事件。

应理解，图6至图8中的示例仅是部分快捷键事件的示例性描述，本申请实施例并不限于此。事实上，其他的快捷键事件采用本申请实施例的方法也能够实现跨系统响应。
还应理解，图6至图8中仅是PC是第一电子设备，平板是第二电子设备为例进行描述，本申请实施例并不限于此。比如，将平板作为第一电子设备，PC作为第二电子设备也是可以实现的。
