1、如何实现修改字体大小，APP内的字体不受影响。修改显示大小，这个时候APP内的字体受影响？
应用设置里面有显示大小和字体大小，想要调整设置里面字体的大小，但是APP内页面字体不受设置里面字体大小档位的影响，当调整设置里面显示大小的档位时，APP内页面字体受影响。
vp单位跟显示大小绑定，fp单位跟字体大小绑定，可将fontSize单位全部转化为vp单位，此时修改字体大小，APP内的字体不受影响。修改显示大小，这个时候APP内的字体受影响。
2、如何设置镜像语言的左右间距？
镜像语言下从右至左展示，但设置的间距right和left没有转换，如何设置镜像语言下，组件外部给的样式属性margin,padding？
API12margin,padding提供外边距类型 LocalizedMargin和 LocalizedPadding，可用于设置不同外边距和内边距。
3、如何能够设置禁止分屏？
可以参考文档https://developer.huawei.com/consumer/cn/doc/harmonyos-guides-V5/multi-window-support-V5#section2205081316，设置module.json5:“supportWindowMode”: [“fullscreen”]。
4、如何控制CustomDialog显示层级？
A页面弹窗一个CustomDialog，若Dialog未关闭时从A页面跳转到B页面，此时会发现在A页面弹出的Dialog会出现在B页面的层级上方，有什么方式可以让B页面盖住Dialog？
可以通过router跳转：
import router from '@ohos.router';@CustomDialog
export default struct UserPrivacyDialog {controller: CustomDialogController = new CustomDialogController({ builder: '' });cancel: Function = () => {};confirm: Function = () => {};visible: Visibility = Visibility.Nonebuild() {Column() {Button('jump').onClick(() => {router.pushUrl({url: 'pages/PageTwo'})}).backgroundColor(0xffffff).fontColor(Color.Red)}.margin({ top: 22 }).justifyContent(FlexAlign.SpaceEvenly)}
}@Entry
@Component
struct Index {@State textValue: string = 'Hello World'@State visible: Visibility = Visibility.Nonebuild() {Stack() {Row() {Column() {Button('click').onClick(() => {if (this.visible == Visibility.Visible) {this.visible = Visibility.None} else {this.visible = Visibility.Visible}}).backgroundColor(0x777474).fontColor(0x000000)}.width('100%')}.height('100%').backgroundColor(0x885555)Text('').onClick(() => {if (this.visible == Visibility.Visible) {this.visible = Visibility.None} else {this.visible = Visibility.Visible}}).width('100%').height('100%')// 透明度可以自己调节一下.opacity(0.16).backgroundColor(0x000000).visibility(this.visible)Column() {GridRow({columns: {xs: 1,sm: 4,md: 8,lg: 12},breakpoints: {value: ["400vp", "600vp", "800vp"],reference: BreakpointsReference.WindowSize},}) {GridCol({span: {xs: 1,sm: 2,md: 4,lg: 8},offset: {xs: 0,sm: 1,md: 2,lg: 2}}) {Column() {Flex({ justifyContent: FlexAlign.SpaceAround }) {UserPrivacyDialog();}.margin({ bottom: 10 })}.backgroundColor(0xffffff).visibility(this.visible).clip(true).borderRadius(20)}}}.width('95%') //设置弹窗宽度}}
}
或者navigation方式跳转：
import promptAction from '@ohos.promptAction';@Component
export struct Test1 {@State message: string = 'Hello World';build() {NavDestination() {Row() {Column() {Text(this.message).fontSize(50).fontWeight(FontWeight.Bold)}.width('100%')}.height('100%')}.onBackPressed(() => {promptAction.showToast({ message: '123' })return false})}
}@Entry
@Component
struct Index {@Provide('pageInfos') pageInfos: NavPathStack = new NavPathStack()@State textValue: string = '输入'// 显隐控制设置为不占用@State visible: Visibility = Visibility.None@BuilderPageMap(name: string) {if (name === 'pageOne') {Test1()}}build() {Navigation(this.pageInfos) {Column() {Stack() {Row() {Column() {Text('我是第一个页面').fontSize(30).fontWeight(FontWeight.Bold)Button('按钮').onClick(() => {console.log("hit me!")if (this.visible == Visibility.Visible) {this.visible = Visibility.None} else {this.visible = Visibility.Visible}}).backgroundColor(0x777474).fontColor(0x000000)}.height('100%').width('100%').justifyContent(FlexAlign.Start).alignItems(HorizontalAlign.Center)}.height('100%').backgroundColor('#FFF')Text('').onClick(() => {if (this.visible == Visibility.Visible) {this.visible = Visibility.None} else {this.visible = Visibility.Visible}}).width('100%').height('100%')// 透明度可以自己调节一下.opacity(0.5).backgroundColor(Color.Black).visibility(this.visible)Column() {GridRow({columns: {xs: 1,sm: 4,md: 8,lg: 12},breakpoints: {value: ["400vp", "600vp", "800vp"],reference: BreakpointsReference.WindowSize},}) {GridCol({span: {xs: 1,sm: 2,md: 4,lg: 8},offset: {xs: 0,sm: 1,md: 2,lg: 2}}) {Column() {Text('安全隐私').fontSize(20).margin({ top: 10, bottom: 10 })Text('是否跳转到隐私详情页面?').fontSize(16).margin({ bottom: 10 })Flex({ justifyContent: FlexAlign.SpaceAround }) {Button('取消').onClick(() => {if (this.visible == Visibility.Visible) {this.visible = Visibility.None} else {this.visible = Visibility.Visible}}).backgroundColor(0xffffff).fontColor(Color.Black)Button('确定').onClick(() => {this.pageInfos.pushPath({ name: 'pageOne' })}).backgroundColor(0xffffff).fontColor(Color.Red)}.margin({ bottom: 10 })}.backgroundColor(0xffffff).visibility(this.visible).clip(true).borderRadius(20)}}}.width('100%') //设置弹窗宽度}}.width('100%').margin({ top: 5 })}.navDestination(this.PageMap)}
}
5、如何在Navigation中使用LocalStorage？
如果是route的页面可以通过@Entry(storage)绑定共享数据，如果导航切换到Navigation应该怎么使用？
LocalStorage的实例仅仅在一个@Entry装饰的组件和其所属的子组件（一个页面）中共享可以借助LocalStorage相关的两个装饰器@LocalStorageProp和@LocalStorageLink，在UI组件内部获取到LocalStorage实例中存储的状态变量。
