HarmonyOS 如何让@CustomDialog自定义弹窗不被软键盘顶起

可以使用半模态弹窗，案例如下：

@Entry
@Component
struct SheetTransition {
  @State isShow:boolean = false
  @State sheetHeight:number = 300;
  private arr: number[] = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9,10,11,12]
  @Builder myBuilder() {
    Column() {
      Button("content1")
        .margin(10)
        .fontSize(20)
      TextInput({placeholder: '请输入内容'})
      Button("content2")
        .margin(10)
        .fontSize(20)
    }
    .width('100%')
  }
  build() {
    Column() {
      Button("transition modal 1")
        .onClick(() => {
          this.isShow = true
        })
        .fontSize(20)
        .margin(10)
        .bindSheet($$this.isShow, this.myBuilder(), {
          height: this.sheetHeight,
          onAppear: () => {console.log("BindSheet onAppear.")},
          onDisappear: () => {console.log("BindSheet onDisappear.")}
        })
      List(){
        ForEach(this.arr,(item:number,)=>{
          ListItem(){Row(){Text('文本')}.justifyContent(FlexAlign.Center).width('100%').backgroundColor(0xFFFFFF).height(100)}
        })
      }.divider({strokeWidth:2,color:'#F1F3F5'}).height('90%')
    }
    .justifyContent(FlexAlign.Start)
    .width('100%')
    .height('100%')
  }
}
