下面是小编为大家整理的HarmonyOS原子化服务卡片immersive（JAVA）体验,供大家参考。
HarmonyOS 原子化服务卡片 immersive（JAVA）体验 一、技术相关 项目名称:
immersive 项目语言:
JAVA 体验模板：immersive 工具：deveco studio
二、体验内容 天气预报样式 小卡片 中卡片 大卡片
三、效果展示 视频 图片
四、开发步骤 新建一个 java 的应用项目 然后构建完成项目后在 jltf_template 下 new->module
选择的 Full screen（java）模板
选择项目的 empty，新建 Service Widget
选择 image and information 模板，点击下一步
选择卡片类型，点击 finish
登录你的账号然后启动模拟器即可实现效果
五 、项目结构介绍
该项目采用了项目模板 full srceen 和卡片模板 immersive，通过两种卡片结合更容易设计 六、 关键代码（MainAbility ）
与样式实现 public class MainAbility extends Ability {
public static final int DEFAULT_DIMENSION_2X2 = 2;
public static final int DIMENSION_1X2 = 1;
public static final int DIMENSION_2X4 = 3;
public static final int DIMENSION_4X4 = 4;
private static final int INVALID_FORM_ID = -1;
private static final HiLogLabel TAG = new HiLogLabel(HiLog.DEBUG, 0x0, MainAbility.class.getName());
private String topWidgetSlice;
@Override
public void onStart(Intent intent) {
super.onStart(intent);
super.setMainRoute(MainAbilitySlice.class.getName());
if (intentFromWidget(intent)) {
topWidgetSlice = getRoutePageSlice(intent);

}
}

}

formName, dimension) : formController;
if (formController == null) {

restart();
}
}
}

}
Class<? extends AbilitySlice> clazz = formController.getRoutePageSlice(intent);
