HarmonyOS Navigation中title怎么居中显示

可以给自定义navigationtitle用row包裹并给与.width(‘100%’).justifyContent(FlexAlign.Center)属性，参考代码如下：

@Entry
@Component
struct Page {
  @State message: string = 'Hello World';

  build() {
    Navigation(){
      Row(){
        Column(){
          Text(this.message)
            .fontSize(  50)
            .fontWeight(FontWeight.Bold)
        }.width('100%')
      }.height('100%')
    }.title(this.navitionTitle)
    .titleMode(NavigationTitleMode.Mini)
    .hideBackButton(true)
    .menus(this.navigationMenus())
  }
  @Builder navitionTitle(){
    Row(){
      Text("购买记录")
        .fontWeight(FontWeight.Bold)
    }.width('100%').justifyContent(FlexAlign.Center)
  }
  @Builder navigationMenus(){
    Row(){
      Image($r('app.media.app_icon'))
        .width(24)
        .height(24)
        .margin({right:14,top:10})
    }
  }
}
