HarmonyOS 鸿蒙Next关于底部自定义弹窗适配键盘安全区域的问题

在YSTestDialog页面的build()组件中的Column()组件下面加上修饰.offset({ x: 0, y: 20}) ，即可解决您的问题，修改之后YSTestDialog页面的完整代码如下，您直接替换即可：

import { WindowUtils } from "../util/WindowsUtil";
import { PromptActionClass } from "./PromptActionClass";
import { YSCustomKeyboard } from "./YSCustomKeyboard";

export class YSTestParams {
  text: string = "";
  onFocusCallBack: () => void = () => {};
  onBlurCallBack: () => void = () => {};

  constructor(text: string, onFocusCallBack: () => void, onBlurCallBack: () => void) {
    this.text = text;
    this.onFocusCallBack = onFocusCallBack;
    this.onBlurCallBack = onBlurCallBack;
  }
}

@Builder
export function YSTestDialogBuilder(param: YSTestParams) {
  YSTestDialog({ testParam: param });
}

@ComponentV2
export struct YSTestDialog {
  @Param testParam: YSTestParams = new YSTestParams("Hello YS!", () => {}, () => {});
  @Local priceInputValue: string = "";
  private inputController: TextInputController = new TextInputController();

  aboutToAppear() {}

  build() {
    Column() {
      TextInput({
        controller: this.inputController,
        placeholder: "点我弹出键盘",
        text: ""
      })
      .placeholderColor($r("app.color.color_9A9A9A"))
      .width($r('app.float.size_200'))
      .height($r('app.float.size_50'))
      .margin($r('app.float.size_35'))
      .borderRadius($r('app.float.size_2'))
      .textAlign(TextAlign.Center)
      .backgroundColor($r('app.color.color_FFFAF7'))
      .customKeyboard(this.customKeyboardBuilder(), { supportAvoidance: true })
      .selectionMenuHidden(true)
      .onFocus(() => {
        this.testParam.onFocusCallBack()
      })
      .onBlur(() => {
        this.testParam.onBlurCallBack()
      });
    }
    .border({ radius: { topLeft: $r('app.float.size_8'), topRight: $r('app.float.size_8') } })
    .width('100%')
    .height($r('app.float.size_200'))
    .padding({ bottom: WindowUtils.getNavigationIndicatorHeight() })
    .backgroundColor($r("app.color.color_FFFFFF"))
    .offset({ x: 0, y: 20 });
  }

  @Builder
  customKeyboardBuilder() {
    YSCustomKeyboard({
      handleInputValue: this.priceInputValue!!,
      inputController: this.inputController,
      defaultInputValue: "0"
    });
  }
}
