# 关机充电动画开发指导 ## 概述 ### 简介 OpenHarmony默认提供了关机充电动画的特性,展示关机状态下的充电电量、充电动画等信息。由于定制厂商希望定制符合自身规则和特点的显示样式,希望根据产品的设计规格来定制此特性。为此OpenHarmony提供了关机充电动画的定制方式,产品定制开发者可根据产品的设计规格来定制此特性。 ### 约束与限制 配置策略: 产品定制的配置路径,需要根据[配置策略](https://gitee.com/openharmony/customization_config_policy)决定。本开发指导中的定制路径以/vendor进行举例,请开发者根据具体的产品配置策略,修改定制路径。 ## 开发指导 ### 搭建环境 设备要求: 标准系统开发板,如DAYU200/Hi3516DV300开源套件。 环境要求: Linux调测环境,相关要求和配置可参考《[快速入门](../quick-start/quickstart-overview.md)》。 ### 开发步骤 本文以[DAYU200](https://gitee.com/openharmony/vendor_hihope/tree/master/rk3568)为例介绍关机充电动画的定制方法。 1. 在产品目录[(/vendor/hihope/rk3568)](https://gitee.com/openharmony/vendor_hihope/tree/master/rk3568)下创建animation文件夹。 2. 参考[默认关机充电动画配置文件夹](https://gitee.com/openharmony/powermgr_battery_manager/tree/master/charger/sa_profile)创建目标文件夹,并安装到`//vendor/hihope/rk3568/animation`目录下,文件格式如下: ```text profile ├── BUILD.gn ├── animation.json ``` 3. 参考[关机充电动画图片资源](https://gitee.com/openharmony/powermgr_battery_manager/tree/master/charger/resources)创建resources文件夹放置构成动画的图片文件,并安装到`//vendor/hihope/rk3568/animation`目录下,文件格式如下: ```text animation ├── resources ├── profile ``` 4. 参考[关机充电动画图片资源中的BUILD.gn](https://gitee.com/openharmony/powermgr_battery_manager/blob/master/charger/resources/BUILD.gn)编写BUILD.gn文件,放入`//vendor/hihope/rk3568/animation/resource`目录下,例如: ```gn import("//build/ohos.gni") ohos_prebuilt_etc("resources_config0") { source = "loop00000.png" #图片资源 relative_install_dir = "poweroff_charger_animation/resources" install_images = [ chipset_base_dir ] #安装到vendor目录下的必要配置 part_name = "product_rk3568" } ``` 5. 参考[默认关机充电动画的配置文件夹中的animation.json](https://gitee.com/openharmony/powermgr_battery_manager/blob/master/charger/sa_profile/animation.json)编写定制的animation.json。包含定制后的关机充电动画配置如下: ```json { "animation": { "components": [ { "type": "UIImageView", "id": "Charging_Animation_Image", "x": 200, "y": 480, "w": 400, "h": 400, "resPath": "/system/etc/charger/resources/", "imgCnt": 62, "updInterval": 60, "filePrefix": "loop" }, { "type": "UILabel", "id": "Charging_Percent_Label", "text": "", "x": 326, "y": 616, "w": 68, "h": 48, "fontSize": 32, "fontColor": "#ffffffe6", "bgColor": "#00000000" "align": "center" } ] }, "lackpowerChargingPrompt": { "components": [ { "type": "UILabel", "id": "LackPower_Charging_Label", "text": "电池电量低", "x": 229, "y": 1037, "w": 250, "h": 45, "fontSize": 42, "fontColor": "#ff0000ff", "bgColor": "#00000000", "align": "center" } ] }, "lackpowerNotChargingPrompt": { "components": [ { "type": "UILabel", "id": "LackPower_Not_Charging_Label", "text": "电池电量低,请连接电源", "x": 110, "y": 1037, "w": 500, "h": 45, "fontSize": 42, "fontColor": "#ff0000ff", "bgColor": "#00000000", "align": "center" } ] } } ``` **表1** 关机充电动画配置说明 | 节点名称 | 作用 | | -------- | -------- | | animation | 动画配置信息 | | lackpowerChargingPrompt| 低电量充电状态提示配置信息 | | lackpowerNotChargingPrompt | 低电量未充电状态提示配置信息 | | components | 组件集 | | type | 组件类型 | | id | 组件ID | | text | 组件的文本内容 | | x | 组件的X轴坐标 | | y | 组件的Y轴坐标 | | w | 组件的宽度(像素点) | | h | 组件的高度(像素点) | | fontSize | 文本的字体大小 | | fontColor | 文本的字体颜色 | | align | 文本对齐方式 | | imgCnt | 图片数量 | | updInterval | 图片更新的时间间隔(毫秒) | | filePrefix | 图片文件名的前缀 | | resPath | 组件的资源文件路径 | 6. 参考[默认关机充电动画的配置文件夹中的BUILD.gn](https://gitee.com/openharmony/powermgr_battery_manager/blob/master/charger/sa_profile/BUILD.gn)编写BUILD.gn文件,将animation.json打包到`/vendor/etc/charger`目录下,配置如下: ```gn import("//build/ohos.gni") ohos_prebuilt_etc("animation_config") { source = "animation.json" #引用build/ohos.gni relative_install_dir = "animation/resources" install_images = [ chipset_base_dir ] #安装到vendor目录下的必要配置 part_name = "product_rk3568" #part_name为product_rk3568,以实现后续编译 } ``` 7. 将编译目标添加到`/vendor/hihope/rk3568`目录下[ohos.build](https://gitee.com/openharmony/vendor_hihope/blob/master/rk3568/ohos.build)的"module_list"中,例如: ```json { "parts": { "product_rk3568": { "module_list": [ "//vendor/hihope/rk3568/default_app_config:default_app_config", "//vendor/hihope/rk3568/image_conf:custom_image_conf", "//vendor/hihope/rk3568/preinstall-config:preinstall-config", "//vendor/hihope/rk3568/resourceschedule:resourceschedule", "//vendor/hihope/rk3568/etc:product_etc_conf", "//vendor/hihope/rk3568/battery/profile:battery_config", "//vendor/hihope/rk3568/animation/profile:animation_config", #添加animation_config的编译 "//vendor/hihope/rk3568/animation/resource/resources_config" #添加图片资源的编译 ] } }, "subsystem": "product_hihope" } ``` “//vendor/hihope/rk3568/animation/”为文件夹路径,“profile”为创建的文件夹名字,“animation_config”为编译目标。 8. 参考《[快速入门](../quick-start/quickstart-overview.md)》编译定制版本,编译命令如下: ```shell ./build.sh --product-name rk3568 --ccache ``` 9. 将定制版本烧录到DAYU200开发板中。 ### 调测验证 1. 修改代码配置: 修改代码路径:base/startup/init/services/init/init_config.c 修改函数:ReadConfig 修改前 ```c void ReadConfig(void) { // parse cfg char buffer[32] = {0}; // 32 reason max leb uint32_t len = sizeof(buffer); SystemReadParam("ohos.boot.mode", buffer, &len); INIT_LOGI("ohos.boot.mode %s", buffer); if (strcmp(buffer, "charger_mode") == 0) { // 产品化定制执行此分支流程 ParseInitCfg(INIT_CONFIGURATION_FILE, NULL); ReadFileInDir(OTHER_CHARGE_PATH, ".cfg", ParseInitCfg, NULL); ParseInitCfgByPriority(); } else if (strcmp(buffer, "charger") == 0) { ParseInitCfg(INIT_CONFIGURATION_FILE, NULL); ReadFileInDir(OTHER_CHARGE_PATH, ".cfg", ParseInitCfg, NULL); } else if (InUpdaterMode() == 0) { ParseInitCfg(INIT_CONFIGURATION_FILE, NULL); ParseInitCfgByPriority(); } else { ReadFileInDir("/etc", ".cfg", ParseInitCfg, NULL); } } ``` 修改后 ```c void ReadConfig(void) { // parse cfg char buffer[32] = {0}; // 32 reason max leb uint32_t len = sizeof(buffer); SystemReadParam("ohos.boot.mode", buffer, &len); INIT_LOGI("ohos.boot.mode %s", buffer); ParseInitCfg(INIT_CONFIGURATION_FILE, NULL); ReadFileInDir(OTHER_CHARGE_PATH, ".cfg", ParseInitCfg, NULL); ParseInitCfgByPriority(); } ``` 2. 使用hdc执行如下命令,使开发板进入关机充电状态。 ```shell hdc shell reboot charge ``` ![animation_initial_power](figures/animation_initial_power.jpg) 3. 进入电池电量的节点路径(以当前DAYU开发版路径为例)。 ```shell cd /data/service/el0/battery/battery ``` 4. 修改电量数值,并观察充电动画数值变化。 ```shell cat capacity ``` 修改当前电量为3 ```shell echo 3 > capacity ``` ![animation_charing_power](figures/animation_charing_power.jpg) 5. 切为Not charging状态,直接进入关机状态。 ```shell echo Not charging > status ``` 6. 在极低电量时(此处默认1%)修改充电状态,不同的充电状态对应显示动画或关机。 1. 进入电池电量的节点路径。 ```shell cd /data/service/el0/battery/battery cat capacity ``` 2. 修改当前电量为1。 ```shell echo 1 > capacity ``` 3. 查看当前状态。 ```shell cat status ``` 当前状态为Charging ![animation_low_power](figures/animation_low_power.jpg) 4. 改变当前状态,为未连接电源状态。 ```shell echo Not charging > status ``` ![animation_low_power2](figures/animation_low_power2.jpg) 7. 以下对关机动画的图片进行可定制化的测试修改,步骤与上方相同,只是图片作出替换。 1. 初始状态。 ![animation_charging_power2](figures/animation_charging_power2.jpg) 2. 3%电量状态。 ![animation_initial_power2](figures/animation_initial_power2.jpg) 3. 1%电量,充电状态。 ![animation_low_power](figures/animation_low_power.jpg) 4. 1%电量,未充电状态。 ![animation_low_power2](figures/animation_low_power2.jpg) 5. 当电量高于1%,切为Not charging状态 ```shell echo 3 > capacity echo Not charging > status ``` ## 参考 开发过程中可参考的配置文件路径:[默认关机充电动画配置源码路径](https://gitee.com/openharmony/powermgr_battery_manager/blob/master/charger/sa_profile/animation.json) 默认配置: ```json { "animation": { "components": [ { "type": "UIImageView", "id": "Charging_Animation_Image", "x": 180, "y": 410, "w": 400, "h": 400, "resPath": "/system/etc/charger/resources/", "imgCnt": 62, "updInterval": 60, "filePrefix": "loop" }, { "type": "UILabel", "id": "Charging_Percent_Label", "text": "", "x": 365, "y": 580, "w": 65, "h": 43, "fontSize": 32, "fontColor": "#ffffffe6", "bgColor": "#00000000", "align": "center" } ], }, "lackpowerChargingPrompt": { "components": [ { "type": "UILabel", "id": "LackPower_Charging_Label", "text": "电池电量低", "x": 229, "y": 1037, "w": 250, "h": 45, "fontSize": 42, "fontColor": "#ff0000ff", "bgColor": "#00000000", "align": "center" } ] }, "lackpowerNotChargingPrompt": { "components": [ { "type": "UILabel", "id": "LackPower_Not_Charging_Label", "text": "电池电量低,请连接电源", "x": 110, "y": 1037, "w": 500, "h": 45, "fontSize": 42, "fontColor": "#ff0000ff", "bgColor": "#00000000", "align": "center" } ] } } ``` 打包路径:/system/etc/charger/resource
