HarmonyOS 使用Navigation后,点击textinput组件,键盘弹起导致Textinput遮挡？

Question

使用navigation导航组件后,navigation里面的内容如果有Textinput,点击textinput弹出键盘,但是textinput并没有向上滑动,而是被遮挡了

这是navigaiton的特性吗?

需要给对应的组件设置 expandSafeArea，这样就能实现效果

参考demo:

import { router } from '@kit.ArkUI';

@Entry
@Component
struct Index {
  @State message: string = 'Hello World';
  @State list: Array<number> = [];
  pathStack: NavPathStack = new NavPathStack()
  aboutToAppear(): void {
    //如果listcount=15点击列表的第14个输入框 键盘弹出就不会将第14个textinput弹起,如果将listcount改成100 点击第14个就将第14个textinput弹起
    let listCount = 25
    for (let index = 0; index < listCount; index++) {
      this.list = this.list.concat(index)
    }
  }

  build() {
    Navigation(this.pathStack) {
      this.buildContent()
    }
    .navBarPosition(NavBarPosition.End)
    .hideTitleBar(true)
  }

  @Builder
  buildContent(){
    Column() {
      List() {
        ForEach(this.list, (index: number, item) => {
          ListItem() {
            TextInput({ placeholder: `输入框${index}` })
          }
          .onClick(() => {

          })
          .width('60%')
          .height(50)
        })
      }
      .expandSafeArea([SafeAreaType.KEYBOARD])
    }
    .width('100%')
    .height('100%')
  }
}

setKeyboardAvoidMode 控制虚拟键盘抬起时页面的避让模式

// EntryAbility.ets
import { KeyboardAvoidMode } from '@ohos.arkui.UIContext';

onWindowStageCreate(windowStage: window.WindowStage) {
  // Main window is created, set main page for this ability
  hilog.info(0x0000, 'testTag', '%{public}s', 'Ability onWindowStageCreate');

  windowStage.loadContent('pages/Index', (err, data) => {
    let keyboardAvoidMode  = windowStage.getMainWindowSync().getUIContext().getKeyboardAvoidMode();
    // 设置虚拟键盘抬起时压缩页面大小为减去键盘的高度
    windowStage.getMainWindowSync().getUIContext().setKeyboardAvoidMode(KeyboardAvoidMode.RESIZE);
    if (err.code) {
      hilog.error(0x0000, 'testTag', 'Failed to load the content. Cause: %{public}s', JSON.stringify(err) ?? '');
      return;
    }
    hilog.info(0x0000, 'testTag', 'Succeeded in loading the content. Data: %{public}s', JSON.stringify(data) ?? '');
  });
}
