具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
在本文中提及的“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这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
相关技术中，可穿戴式设备中设置有单一处理器，并通过运行在处理器上的操作系统，对设备运行过程中产生的所有系统事件进行处理，因此该处理器需要具备较强的数据处理能力，并在设备运行过程中保持工作状态。然而，在日常使用过程中，可穿戴式设备在大多数情况下只需要实现一些对处理性能要求较低的功能，比如，对于智能手表或智能手环来说，大多数情况下，智能手表或智能手环只需要进行时间显示和消息提示。因此，长时间保持处理器处于工作状态并不会提高可穿戴式设备的性能，反而会增加设备功耗，导致可穿戴式设备的续航时间较短。
为了在保证可穿戴式设备性能的同时，降低可穿戴式设备的功耗，在一种可能的实施方式中，可穿戴式设备至少设置具有不同处理性能以及功耗的第一处理器和第二处理器，分别用于运行第一系统和第二系统(即双核双系统)，并为双核双系统设计了一套系统切换机制。
可穿戴式设备运行过程中，通过运行在低功耗处理器上的第一系统，对低性能处理需求的事件进行处理，并保持高功耗处理器处于休眠状态(相应的，由高功耗处理器运行的第二系统处于休眠状态)，在实现可穿戴式设备基础功能的同时，降低可穿戴式设备的功耗；当存在高性能处理需求的事件时(比如启动应用程序时)，通过唤醒高功耗处理器，并切换第二系统对事件进行处理，保证触发的事件能够被及时响应并处理，满足可穿戴式设备的性能需求。
并且，由于高功耗处理器从休眠状态切换为唤醒状态需要耗费一定时间(至少需要200ms至300ms)，因此为了降低切换系统过程中系统画面的显示延迟，本申请引入了系统切换效果预展示机制，在高功耗处理器切换唤醒的情况下，由低功耗处理器运行的第一系统绘制并展示第二用户界面；当高功耗处理器绘制完第二用户界面后，再由高功耗处理器运行的第二系统接收用户界面展示权限，实现系统切换的预展示，从而提升视觉上系统切换的启动速度，降低系统切换过程中用户界面的显示延迟。
本申请实施例中，由于第一处理器和第二处理器异步工作，且第一系统和第二系统需要 实现系统通信(或称为双核通信)。在一种可能的应用场景下，第一系统为运行在微控制单元(Micro Controller Unit，MCU)上的实时操作系统(Real Time Operating System，RTOS)，且第二系统为运行在中央处理器(Central Processing Unit，CPU)上的安卓(Android)操作系统。
如图1所示，其示出了本申请一个示例性实施例示出的安卓操作系统的双核通信软件框架。该双核通信软件框架遵循“低耦合，高可靠，高复用”的设计原则，包括Kernel(内核)、HIDL(硬件抽象层接口描述语言)、Native Service(本地服务)、Framework Service(框架服务)、Framework API(框架接口)和APP(应用)部分的模块开发。
其中，APP模块包括Launcher(桌面启动器)、Setting(设置)和SystemUI(系统用户界面)等功能模，Framework API模块中包括MCUManager(MCU管理)、SensorManager(传感器管理)、LocationManager(位置管理)等管理模块，Framework Service模块中包括MCUManagerService(MCU管理服务)、SystemSensorManager(系统传感器管理)、LocationManagerService(位置管理服务)等服务模块，Native Service模块包括dccservice(dcc服务)、Sensorservice(传感器服务)等服务模块，HIDL模块包括Sensor HAL(传感器硬件抽象层)、GPS HAL(全球定位系统硬件抽象层)等模块。Kernel模块包括dcc_datah、dcc_data、Mcu_sensor、Mcu_gps、Mcu_factory等DCC Transfer Driver(DCC传输驱动)。
传输层作为双核通信软件框架中衔接上下层的接口层，向应用层屏蔽系统下层(数据链路层)通信的传输细节，为应用场景提供服务通道；应用层作为服务提供的主体，响应于人机交互并通过传输层对人机交互过程中产生的数据进行传输，以及对外部数据请求进行响应。
RTOS采用对等原则进行设计。以可穿戴式设备为智能手表为例，如图2所示，其示出了本申请一个示例性实施例示出的RTOS的双核通信软件框架。
RTOS的双核通信软件框架分为应用层(Application Layer)、服务层(Service Layer)、框架层(Framework Layer)、硬件抽象层(Hardware abstraction layer)和平台层(PlatformLayer)。
其中，应用层包括watch face(表盘)、Daily Tracker(日常追踪)、Message center(消息中心)、Voice around Apps(声音应用)、Health Apps(健康应用)、Settings(设置)等应用模块；服务层包括Sport&health task(运动健康任务)、System manager task(系统管理任务)、AMS(活动管理服务)、AudioService(音频服务)、Log Service(日志服务)、OFTP Service(Odette文件传输协议服务)、BT Service(蓝牙服务)、Delegate Service(转交服务)、RPC Service(远程调用服务)、sensor Service(传感器服务)、storage Service(存储服务)等服务模块；框架层包括Message Pub(消息中心)、UI Framework(用户界面框架)、G2D Engine(G2D殷勤)、Audio Middleware(音频中间件)、Preference(偏好)、File system(文件系统)、Algorithms(算法)、Aios、AsycEvent(进程内异步事件)等框架模块；硬件抽象层包括Screen/TP(屏幕/触控屏)、Audio(音频)、GPS(全球定位系统)、sensors(传感器)、Keypad(键盘)、Motor(马达)等硬件抽象模块；平台层包括板级支持包(Board Support Package，BSP)以及低等级驱动(LOW level Driver)，其中，BSP包括Screen/TP、Keys(按键)、GPS、Codec(编码译码器)、sensors、Flash(闪存)、Motor、PSRAM(伪静态随机存储器)等等，低等级驱动包括Uart(通用异步收发传输器)、ADC(模数转换器)、GPIO(通用输入输出)、SPI(串行外设接口)、I2C(集成电路总线)、IOS(输入输出系统)、PCM(脉冲编码调制)、I2S(集成音频总线)、HWTimer(硬件定时器)。
需要说明的是，上述双核通信软件框架仅用于示意性说明，本领域技术人员还可以根据实际需求，对上述框架进行增加、删除或修改，本申请实施例并不对双核通信软件框架的具体结构构成限定。

可选的，可穿戴式设备设置有第一处理器和第二处理器，第二处理器的功耗高于第一处理器的功耗，且第一系统是由第一处理器运行的系统，第二系统是由第二处理器运行的系统。
请参考图3，其示出了本申请一个示例性实施例提供的用户界面的用户界面显示方法的流程图，本实施例以该方法应用可穿戴式设备，且可穿戴式设备支持运行第一系统和第二系 统为例进行说明，该方法可以包括如下步骤。
步骤301，在第一系统处于唤醒状态，且第二系统处于休眠状态的情况下，通过第一系统显示第一用户界面。
在一种可能的实施方式中，可穿戴式设备设置有第一处理器和第二处理器，其中，第一处理器的处理性能低于第二处理器的处理性能(第一处理器的处理能力和处理速度均低于第二处理器)，且第一处理器的功耗低于第二处理器的功耗。相应的，第二系统(由第二处理器运行)能够处理第一系统(由第一处理器运行)所处理的事件，而第一系统并不一定能够处理第二系统所处理的事件。
在另一种可能的实施方式中，可穿戴式设备也可以设置单一处理器，第一系统和第二系统分别运行在处理器的不同核心上，其中，运行第二系统的核心的处理性能高于运行第一系统的核心的处理性能。
比如，以可穿戴式设备为智能手表为例，第一处理器为MCU，第二处理器为CPU，第一系统为RTOS，第二系统为安卓系统。相应的，第一系统所能处理的事件包括表盘显示、表盘界面切换、通知消息显示等对处理性能要求较低的场景或弱交互场景；第二系统所能处理的事件包括来电接听、启动应用、表盘编辑、功能设置等对处理性能要求较高的场景或强交互场景。
在一种可能的实施方式中，可穿戴式设备的工作模式包括性能模式、混动模式和低功耗模式，其中，性能模式下，第二处理器和第一处理器均保持唤醒状态(相应的，第一系统和第二系统均处于唤醒状态)；低功耗模式下，仅第一处理器保持唤醒状态(正常工作状态)，而第二处理器保持关闭状态(即第一系统处于唤醒状态，第二系统处于关闭状态)；混动模式下，第一系统处理事件时，第二处理器保持休眠状态，第二处理器处于待机状态，可以在休眠和唤醒状态之间切换(即第一系统处于唤醒状态时，第二系统既可以处于唤醒状态，又可以处于休眠状态)。
可选的，唤醒状态下，系统相关数据缓存在内存(RAM)中，以便于随时运行系统相关数据，休眠状态下，处理器大部分硬件模块关闭，系统相关数据存储在硬盘(ROM)中，并在切换为唤醒状态时由硬盘写入内存中。
不同于智能手机一类具有强交互属性的电子设备，可穿戴式设备作为一种辅助性的电子设备，在绝大多数使用场景下与用户之间仅存在弱交互。比如，用户在大部分场景下仅通过智能手表进行抬腕查看时。因此，可穿戴式设备通过第一系统对事件进行处理时，控制第二处理器处于休眠状态(第二系统处于休眠状态)，从而降低可穿戴式设备的整体功耗。
步骤302，响应于系统切换指令，通过第一系统绘制并显示第二用户界面，第二用户界面为第二系统的用户界面。
其中，系统切换指令用于指示切换前台运行的系统，即需要将前台运行的系统由第一系统切换为第二系统，而非单纯将处于休眠状态的第二系统切换为唤醒状态，相应的，可穿戴式设备的图形用户界面的展示权限将由第一系统切换为第二系统。
在一些可能的应用场景下，当用户需要使用第一系统显示的第一用户界面中不具备的功能时，用户需要将第一系统切换为第二系统，从第二系统显示的第二用户界面中选择需要使用的功能。
在第一系统处于唤醒状态(可穿戴式设备的界面为第一系统显示的第一用户界面)，且第二系统处于休眠状态的情况下，当接收系统切换指令时，表明需要将第一系统切换为第二系统，由于第一系统并不具备处理相应事件的功能和能力，因此需要唤醒处于休眠状态的第二系统，从而通过第二系统进行处理。
然而，由于第二系统的唤醒和显示的过程需要花费一定时间(至少需要200ms至300ms)，因此在系统切换的过程中会出现短暂无响应现象(表现为接收到系统切换指令到显示切换动画之间存在一定延迟，第二系统在该延迟时间内唤醒，并通过第二系统完成第二用户界面绘 制显示)，影响使用体验。本申请实施例中，为了降低系统切换过程中第二用户界面的显示延迟，当在第一系统运行过程中接收到切换第二系统的系统切换指令时，首先通过第一系统绘制第二系统的第二用户界面并进行显示(仅负责绘制界面图像，并非在第一系统下执行第二系统所具备的特定功能，如第二用户界面显示有应用图标，第一系统只是显示应用图标，但是该应用图标并不具备启动应用的功能)。
可选的，系统切换指令为通过快捷键(比如可穿戴式设备上设置的物理按键)触发的指令，或者通过滑动(比如通过单指或双指滑动可穿戴式设备的显示界面)触发的指令，或者通过点击(比如通过单击或双击可穿戴式设备的显示界面)触发的指令；第二用户界面可以显示有运动健康图标、即时通讯图标、闹钟图标、天气图标、语音助手等图标，且显示的第二用户界面可以为静态界面，也可以是动态界面。本申请实施例并不对系统切换指令的触发方式、第二用户界面显示的内容进行限定。
由于第一系统处于唤醒状态，因此第一系统在接收到系统切换指令后可以立即进行第二用户界面绘制并显示，从而实现视觉上提升系统切换速度。
在一种可能的实施方式中，为了实现界面的平滑切换，当第一系统绘制出第二用户界面后，采用滑动显示的方式逐渐替代第一用户界面，直至完全显示出第二用户界面，可选的，第二用户界面还可以是旋转显示或劈裂方式显示，本申请实施例不对第二用户界面的具体显示方式进行限定。
示意性的，如图4所示，以可穿戴式设备为智能手表为例，智能手表中设置有RTOS(由第一处理器运行)和安卓系统(由第二处理器运行)。第一处理器处于唤醒状态，而第二处理器处理休眠状态时，智能手表通过RTOS显示第一用户界面41，安卓系统处于休眠状态，从而保持较低的功耗。当用户需要将RTOS切换为安卓系统时，可以通过滑动操作触发系统切换指令。相应的，RTOS接收到系统切换指令后，绘制并显示安卓系统的第二用户界面42并进行显示。
步骤303，响应于第二系统绘制完成第二用户界面，通过第二系统显示第二用户界面。
第二系统完成第二用户界面绘制后，可穿戴式设备运行的系统即由第一系统切换为第二系统，从而通过第二系统对第二用户界面进行显示，并执行相应的功能，如，用户需要使用通话功能时，通过触发第二用户界面上的即时通讯应用进入通讯界面。由于第一系统和第二系统绘制并显示的第二用户界面保持一致，因此并不会出现系统切换前后画面突变的问题，使系统切换过程不易被察觉。
可选的，切换至第二系统后，第一系统仍旧在后续处于唤醒状态(低功耗，对续航影响较小)，或者第一系统切换为休眠状态，本实施例对此不作限定。
在一种可能的实施方式中，为了确保第一系统绘制并完全显示第二用户界面后，系统及时切换为第二系统，避免出现第一系统完全显示出第二用户界面后，用户点击图标无响应的情况(此时的第二用户界面由第一系统绘制并显示)，根据第二系统唤醒并绘制出第二用户界面的时间确定第二用户界面的滑动速度，确保第一用户绘制的第二用户界面完全占据可穿戴式设备的显示界面时，第二系统已绘制出第二用户界面，在用户无感知情况下实现系统切换。
示意性的，如图4所示，RTOS显示第二用户界面42的过程中，第二用户界面42从左向右滑动显示，直至第一用户界面41完全切换为第二用户界面42，第二用户界面42从左向右滑动显示过程中，安卓系统由休眠状态切换为唤醒状态，当安卓系统唤醒并绘制完成后(比如经过200ms)，智能手表运行的系统由RTOS切换为安卓系统，并通过安卓系统显示第二用户界面43。
可选的，第二系统完成事件处理后(比如通话结束返回表盘)，第二系统重新切换回休眠状态，并继续通过第一系统处理事件，使可穿戴式设备在少部分场景下保持高性能(但是高功耗)，而在大多数场景下保持低功耗(但低性能)，进一步降低可穿戴式设备的功耗，延长可穿戴式设备的续航时间。
综上所述，本申请实施例中，对于支持双系统的可穿戴式设备，若在第一系统处于运行状态而第二系统处于休眠状态的情况下，接收到系统切换指令，首先由第一系统绘制并显示第二用户界面，并在第二系统绘制完成第二用户界面后，通过第二系统显示第二用户界面；采用本申请实施例提供的方案，通过第一系统预展示第二用户界面，能够提升视觉上系统切换的启动速度，降低系统切换过程中第二系统显示第二用户界面的显示延迟。
在一种可能的实施方式中，第一系统和第二系统各自对应有数据存储空间，且由于第一系统仅负责处理简单事件，而第二系统则需要处理复杂事件，因此第二系统对应的存储空间远大于第一系统对应的存储空间。为了实现通过第一系统绘制并显示第二用户界面，第一系统对应的存储空间中存储第二用户界面对应的用户界面资源，接收到系统切换指令后，第一系统即基于存储空间中的用户界面资源进行用户界面绘制。下面采用示例性的实施例进行说明。
请参考图5，其示出了本申请另一个示例性实施例提供的用户界面的显示方法的流程图，本实施例以该方法应用可穿戴式设备为例进行说明，该方法可以包括如下步骤。
步骤501，在第一系统处于唤醒状态，且第二系统处于休眠状态的情况下，响应于系统切换指令，通过第一系统从第一存储空间获取第二用户界面对应的用户界面资源，第一存储空间为第一系统对应的存储空间。
本申请实施例中，第一系统对应有第一存储空间，第一存储空间中存储有至少一个用户界面所对应的用户界面资源，该用户界面资源指绘制用户界面所需的资源，该用户界面资源可以包括文字资源、图片资源、动画资源、特效资源、界面布局资源等等，本实施例对界面资源中包含的具体内容不做限定。
在一种可能的实施方式中，第一存储空间中存储有第一系统对应第一用户界面的用户界面资源，以及第二系统对应第二用户界面对应的用户界面资源。比如，第一用户界面为手表表盘时，第一存储空间存储由表盘资源，当第二系统中安装有运动健康应用、闹钟应用、即时通讯应用时，在第二用户界面即显示有对应的运动健康图标、闹钟应用图标、即时通讯图标，相应的，第一存储空间中即存储有各个应用图标对应的图标资源，可选的，第二用户界面还可以显示有桌面挂件和语音助手，相应的，在第一存储空间中也存储有对应的用户界面资源。
在一些实施例中，第一系统基于所需绘制的界面元素，从第一存储空间中查找该界面元素对应的界面元素资源。
在一个示意性的例子中，第一存储空间中界面元素与界面元素资源之间的映射关系如表一所示。
表一
界面元素 界面元素资源
即时通讯图标 界面元素资源A
闹钟图标 界面元素资源B
天气图标 界面元素资源C
运动健康图标 界面元素资源D
如表一所示，当第二用户界面显示有即时通讯应用的图标时，第一系统即从第一存储空间中获取界面元素“即时通讯图标”对应的界面元素资源A。
步骤502，响应于界面元素中包含可变界面元素，基于当前时刻确定可变界面元素对应的目标界面元素资源，其中，可变界面元素对应至少两种界面元素资源，且不同界面元素资源对应不同显示时段。
在根据界面元素获取界面元素资源时，除了需要确定界面元素中的固定界面元素外(例如闹钟应用和即时通讯应用的图标都是固定界面元素)，还需要确定出可变界面元素(例如时 间显示挂件和问候语是可变界面元素)。
其中，可变界面元素在不同时段内的表现形式可能不同，即可变界面元素可能对应多个界面元素资源，因此在绘制可变界面元素时，第一系统还需要利用到其他数据，比如时间数据，传感器数据(比如计步器数据)等等，从而保证绘制出的第二用户界面中的界面元素的准确性和一致性，避免出现第一系统和第二系统绘制的界面元素出现差异，出现系统切换时用户界面出现突变的问题。
在一种可能的实施方式中，当需要绘制的界面元素包含有可变界面元素时，第一系统基于当前时刻，从可变界面元素对应的至少两种界面元素资源中确定目标界面元素资源，其中，不同界面元素资源对应不同显示时段，且当前时刻所属的显示时段为目标界面元素资源对应的显示时段。
比如，可变界面元素为问候语，0:00至12:00这一时段对应的界面元素为“早上好”，12:00至17:00这一时段对应的界面元素为“下午好”，“17:00至24:00”这一时段对应的界面元素为“晚上好”。
示意性的，当需要绘制的第二用户界面中包含有问候语时(问候语根据时间段在用户界面显示上午好、下午好和晚上好等文字信息)，若当前时间为十点，第一系统将当前时刻所属时段对应的界面元素资源“上午好”确定为目标问候语。
步骤503，基于目标界面元素资源绘制可变界面元素。
进一步的，获取到对应的界面资源后，第一系统即根据确定的目标界面资源绘制对应的界面元素。
在一个示例性的例子中，第一系统获取到界面资源中包含应用图标对应图片资源以及问候语对应的文字资源，从而基于图片资源渲染出应用图标，基于文字资源渲染出问候语。
步骤504，将界面元素显示在显示位置信息所指示的界面元素位置，得到第二用户界面。
第一系统根据用户界面资源中包含的界面元素的位置信息确定第二用户界面中各个界面元素的排列布局，并显示出第二用户界面。
在一种可能的实施方式中，如图6所示，第二用户界面600的上方显示有语音助手610，语音助手610中显示有问候语611，问候语611根据当前时间段显示不同的文字信息，第二用户界面600的下方显示有即时通讯图标620、闹钟图标630、运动健康图标640等应用图标。需要说明的是，此时的第二用户界面600是由第一系统绘制并显示出，显示出的界面元素不具备相应的功能，也就是说，当用户点击即时通信图标620后，不会响应也不会展示通讯界面。
步骤505，基于滑动操作的滑动方向，通过第一系统显示由第一用户界面切换为第二用户界面的切换动画。
第一系统绘制出第二用户界面后，基于滑动操作的滑动方向，将第一用户界面滑动切换为第二用户界面，其中滑动操作的滑动方向由用户在第二系统下设定，如采用左右切换、飞入和劈裂等切换动画。
示意性的，如图4所示，第一系统绘制出的第二用户界面402采用左右切换的方式进行切换。需要说明的是，本实施例不对用户界面的切换动画进行限定。
步骤506，响应于第二系统绘制完成第二用户界面且滑动操作结束，通过第二系统显示第二用户界面。
当第二用户界面滑动结束，即由第一用户界面切换为第二用户界面，此时，第二系统已唤醒并绘制出第二用户界面中包含的所有界面元素，将第一系统切换为第二系统，通过第二系统显示第二用户界面，由于系统切换前后的第二用户界面中包含的界面元素相同，因此实现了在用户无感知情况下实现了系统切换。
为了保证系统切换完成后由第二系统控制可穿戴式设备的界面显示，当第二系统绘制完成第二用户界面后，通过向第一系统发送切换指令的方式获取界面显示的控制权限，第二系 统获取到控制权限后，可穿戴式设备的显示界面将由第二系统控制，第一系统可以进入休眠状态或关闭状态。
可选的，响应于第二系统绘制完成第二用户界面，可穿戴式设备通过第二系统向第一系统发送切换指令，切换指令用于指示第一系统转移图形用户界面(Graphical User Interface，GUI)的展示权限。
为了保证第二用户界面的正常使用，在进行系统切换过程中，第一系统需要将图形用户界面的展示权限转移给第二系统，以便第二系统正常运行过程中可以向可穿戴式设备展示第二系统的图形用户界面。在一种可能的实施方式中第二系统绘制完成第二用户界面后，会向第一系统发送切换指令，指示第一系统向第二系统转移图形用户界面的展示权限。
响应于第二系统获取到图形用户界面的展示权限，可穿戴式设备通过第二系统显示第二用户界面。
第二系统获取到图形用户界面的展示权限后，可穿戴式设备将由第一系统切换为第二系统，通过第二系统显示第二用户界面，在第二系统显示的第二用户界面中，显示的界面元素具备相应的功能，如通过点击即时通讯图标进入通讯界面。
本实施例中，通过在第一存储空间中存储第二用户界面对应的用户界面资源，使得第一系统接收到系统切换指令后，能够基于第二用户界面中包含的可变界面元素和固定界面元素从第一存储空间中准确获取对应的目标界面元素资源，进一步的基于显示位置信息在第二用户界面显示界面元素，有助于提高第二用户界面的绘制速度和显示的准确性。
并且，通过第一系统预展示第二用户界面的方式，能够提升视觉上系统切换的启动速度，降低系统切换过程中第二系统显示第二用户界面的显示延迟。
此外，在第二系统完成第二用户界面的绘制后，通过向第一系统发送切换指令获取图形用户界面展的示权限，确保第二系统在正常运行过程中向可穿戴式设备展示图形用户界面。
上述实施例中，由于可穿戴式设备中第二系统的第二用户界面并非保持不变，如调整第二用户界面中界面元素的顺序、添加及删除在第二用户界面显示的界面元素等，因此为了保证切换系统后第二用户界面显示的准确性，第一存储空间中存储的用户界面资源也需要进行相应的更新。在一种可能的实施方式中，在第二系统处于唤醒状态或重启的情况下，第二系统自动向第一系统发送界面资源更新数据(存在界面资源更新事件时)，第一系统即基于界面资源更新数据，更新第一存储空间中存储的用户界面资源。其中，该用户界面资源更新数据中至少包括待更新界面元素对应的界面元素资源。
请参考图7，其示出了本申请一个示例性实施例提供的用户界面资源更新过程的流程图，该方法可以包括如下步骤。
步骤701，在第二系统处于唤醒状态的情况下，通过第二系统向第一系统发送界面资源更新数据，界面资源更新数据采用第一系统与第二系统约定的数据格式。
在一种可能的实施方式中，在第二系统处于唤醒状态的情况下，当第二系统检测到界面资源变更事件时，通过连接第一系统和第二系统的数据链路向第一系统发送界面资源更新数据，界面资源变更事件包括界面元素增删事件、界面元素位置调整事件和系统设置变更事件中的至少一种。其中系统设置变更事件包括系统语言变更、系统文字字体变更、系统文字字号变更、系统风格变更等等，本实施例对此不作限定。
在另一种可能的实施方式中，每次第二系统重启后，均需要向第一系统发送界面资源更新数据，以此保证第一系统与第二系统中第二用户界面对应界面资源的一致性。
可选的，当第二系统确定发生界面资源变更事件后，将第二用户界面对应的界面资源更新数据按照约定的协议编码成字节流，并且将字节流打包后通过数据链路发送给第一系统，界面资源更新数据采用第一系统与第二系统约定的数据格式。
在一个示例性的例子中，第二系统向第一系统发送数据的格式如下。
Figure PCTCN2022078423-appb-000001
当第一系统接收到第二系统发送的数据包后，按照与第二系统约定的协议对数据包进行解码，获取更新后第二用户界面对应的用户界面资源。
步骤702，基于界面资源更新数据，通过第一系统更新第一存储空间中存储的用户界面资源。
接收到界面资源更新数据后，第一系统即将更新后的界面元素与更新后的界面元素资源进行关联存储，后续系统切换过程中，第一系统即可基于更新后的界面元素资源进行第二用户界面绘制和显示，保证显示的第二用户界面与第二系统的用户界面保持一致。
结合上述步骤的示例，第一系统基于接收到的数据包更新界面元素资源后，第一存储空间中界面元素与界面元素资源之间的映射关系如表二所示。
表二
界面元素 界面元素资源
即时通讯图标 界面元素资源A’
闹钟图标 界面元素资源B’
天气图标 界面元素资源C
运动健康图标 界面元素资源D
如表二所示，结合上述步骤中的示例，即时通讯图标以及闹钟图标对应的界面元素资源A和界面元素资源B发生更新，第一系统基于接收到的界面资源更新数据，得到更新后的界面元素资源A’和界面元素资源B’。
以语言更新为例，当第二用户界面的显示语言由中文显示更新为英文显示时，将界面元素资源中的中文文本信息更新为英文文本信息。
示意性的，如图8所示，RTOS处于工作状态时显示第一用户界面81，当需要进行系统切换时，通过滑动操作进行系统切换，第一系统基于更新后的用户界面资源绘制并显示第二用户界面82，第二用户界面82中显示的界面元素由中文状态更新为英文状态。
可选的，完成用户界面资源更新后，第一系统向第二系统发送更新完成通知，告知第二系统已完成对用户界面资源的更新。若第二系统在预设时长内未接收到更新完成通知，则重新向第一系统发送更新数据包。
在另一种可能的实施方式中，第二系统向第一系统更新的数据包中包含第二用户界面中所有界面元素对应的界面元素资源，相应的，当可穿戴式设备的系统语言发生变更时，第一存储空间内存储的大部分用户界面资源可能已经无效，因此为了释放第一存储空间，并保证后续用户界面资源更新的准确性，当接收到第一系统的更新数据包时，第一系统将删除第一存储空间中的用户界面资源，直接将接收到的更新数据包进行解码，获取更新后的第二用户界面包对应的用户界面资源。
示意性的，如图9所示，以第一系统为RTOS，第二系统为安卓系统为例，当第二用户界面发生改变，确认发生系统设置变更事件，安卓系统即向第RTOS发送更新数据包，更新数据包中包含更新后的第二用户界面对应的用户界面资源，当RTOS接收到数据数据包时，确定第二用户界面发生改变，即删除第一存储空间中包含的用户界面资源，并根据接收到的数据包进行解码，获取更新后的用户界面资源并存储至第一存储空间，可选的，当RTOS完成更新后，向安卓系统发送完成更新通知。
本实施例中，当用户界面资源更新时，第二系统通过确认界面资源变更事件，从而将更新后的用户界面资源发送至第一系统，由第一系统对第一存储空间中存储的用户界面资源进行更新，确保后续进行系统切换时，第一系统显示的第二用户界面与第二系统显示的第二用户界面保持一致，实现无感知切换。
需要说明的是，上述各个实施例中，仅以双核双系统设备下用户界面的显示过程为例进行说明，在其他可能的应用场景下，单核双系统(比如处理器不同核心上运行不同系统)设备也可以采用本申请实施例提供的方案实现系统切换过程中用户界面的显示，本实施例在此不作赘述。
