1、实现沉浸式导航栏效果

1）在config.json中配置如下：

"module": {
    "abilities": [{
         "metaData": {
              "customizeData": [{
                  "name": "hwc-theme",
                  "value": "androidhwext:style/Theme.Emui.Translucent.NoTitleBar"
                }]
          }
        ...
    }]
}

2）在Ability代码onStart方法中编写

getWindow().addFlags(WindowManager.LayoutConfig.MARK_TRANSLUCENT_NAVIGATION);

2、页面跳转及传递参数

参数可以是模型、字符串等

Intent intent = new Intent();
List<String> list = new ArrayList<String>();
list.add(token);
list.add("2");
intent.setParam(Const.ABILITY_PARAMETER_KEY, (Serializable)list);
present(new NoticeAbilitySlice(), intent);
