HarmonyOS鸿蒙Next中ArkTS固定头部导航栏以及修改状态栏

HarmonyOS鸿蒙Next中ArkTS固定头部导航栏以及修改状态栏 问题前提：页面因为会超过一屏，所以使用了Scroll来进行滚动，并且页面设置有一张背景图片。使用Flex自定义了一个头部导航，但是因为头部导航需要显示出页面设置的背景图片的，并且在滚动时，头部导航会变成白色浮在页面中，当滚动到页面顶部时，导航又是透明的显示出页面的背景 。状态栏也需要设置成透明的显示页面设置的背景图片

问题：1、因为将头部导航放在了Scroll中使用position等方法都没法将导航固定在页面上，会随着页面滚动

2、状态栏不知道怎么设置成透明的且显示页面设置的背景图

想实现的效果就和淘宝这里一样

问题1：容器外层是否包裹了定位容器，Stack/RelativeContainer，包裹了之后position才能生效;

问题2：状态栏设置参考 https://developer.harmonyos.com/cn/docs/documentation/doc-guides/window-guidelines-0000001281480814；

api几呀，如果是api10，会提供一个安全区域，可以保证不被顶上去。

在HarmonyOS鸿蒙Next中，使用ArkTS实现固定头部导航栏和修改状态栏的方法如下：

  1. 固定头部导航栏：

    • 使用@Component装饰器创建自定义导航栏组件。
    • 在build方法中使用Stack布局，将导航栏组件固定在页面顶部。
    • 设置position属性为fixed，确保导航栏在滚动时保持固定。

  2. 修改状态栏：

    • 使用SystemUI模块中的setStatusBarColor方法设置状态栏背景色。
    • 使用setStatusBarStyle方法设置状态栏文字颜色（亮色或暗色）。
    • 在onPageShow生命周期中调用这些方法，确保页面显示时状态栏样式生效。

通过这些步骤，可以实现固定头部导航栏和自定义状态栏样式。
