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。由于定制厂商盼望定制符合自身规则和特点的显示样式,盼望根据产物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,产物定制开辟者可根据产物的设计规格来定制此特性。
约束与限制
配置计谋: 产物定制的配置路径,必要根据[配置计谋]决定。本开辟指导中的定制路径以/vendor进行举例,请开辟者根据详细的产物配置计谋,修改定制路径。
开辟指导
搭建环境

标准系统开辟板,如DAYU200/Hi3516DV300开源套件。
环境要求:
Linux调测环境
开辟步骤
本文以[DAYU200]为例介绍关机充电动画的定制方法。
- 在产物目次[(/vendor/hihope/rk3568)]下创建animation文件夹。
- 创建目标文件夹,并安装到//vendor/hihope/rk3568/animation目次下,文件格式如下:
- profile
- ├── BUILD.gn
- ├── animation.json
复制代码 - 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目次下,文件格式如下:
- animation
- ├── resources
- ├── profile
复制代码 - 编写BUILD.gn文件,放入//vendor/hihope/rk3568/animation/resource目次下,例如:
- 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"
- }
复制代码 - 编写定制的animation.json。包含定制后的关机充电动画配置如下:
- {
- "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"
- }
- ]
- }
- }

- 编写BUILD.gn文件,将animation.json打包到/vendor/etc/charger目次下,配置如下:
- 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
- }
复制代码 - 将编译目标添加到/vendor/hihope/rk3568目次下[ohos.build]的"module_list"中,例如:
- {
- "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"
- }
复制代码 “//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。
- 编译定制版本,编译命令如下:
- ./build.sh --product-name rk3568 --ccache
复制代码 - 将定制版本烧录到DAYU200开辟板中。
调测验证
- 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
- 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);
- }
- }
复制代码 修改后
- 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();
- }
复制代码 - 利用hdc执行如下命令,使开辟板进入关机充电状态。
- 进入电池电量的节点路径(以当前DAYU开辟版路径为例)。
- cd /data/service/el0/battery/battery
复制代码 - 修改电量数值,并观察充电动画数值变化。
修改当前电量为3
- 切为Not charging状态,直接进入关机状态。
- echo Not charging > status
复制代码 - 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。
- cd /data/service/el0/battery/battery
- cat capacity
复制代码 当前状态为Charging
- echo Not charging > status
复制代码
- 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。
- echo 3 > capacity
- echo Not charging > status
复制代码
