HarmonyOS 如何修改手机顶部状态栏的图标字体颜色

可以通过setWindowSystemBarProperties修改页面属性，参考文档：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-window-V5#setwindowsystembarproperties9

参考demo:

import { window } from '@kit.ArkUI'
@Entry
@Component
struct NavigationExample {
  @State text: string = ''
  aboutToAppear(): void {
    window.getLastWindow(getContext(this)).then((data) => {
      data.setWindowSystemBarProperties({
        statusBarContentColor:'#FFE50F0F'
      })
    })
  }
  build() {
    Column() {
      TextInput({ text: this.text, placeholder: 'input your word...' })
        .placeholderColor(Color.Grey)
        .placeholderFont({ size: 14, weight: 400 })
        .caretColor(Color.Blue)
        .width('95%')
        .height(40)
        .margin(20)
        .fontSize(14)
        .fontColor(Color.Black)
        .inputFilter('^[\u4e00-\u9fa5a-zA-Z0-9]+$')
        .onChange((value: string) => {
          this.text = value
        })
    }
  }
}
