@Entry
@Component
struct TestGetWindowAvoidArea {
  @State message: string = '获取屏幕顶部状态栏、底部导航栏和导航条的高度';

  getAvoidAreaHeight() {

    let type2 = window.AvoidAreaType.TYPE_NAVIGATION_INDICATOR;
    window.getLastWindow(getContext(this)).then((data) => {
      // 获取系统默认区域，一般包括状态栏、导航栏
      let avoidArea1 = data.getWindowAvoidArea(type1);
      // 顶部状态栏高度
      let statusBarHeight = avoidArea1.topRect.height;
      // 底部导航栏高度
      let bottomNavHeight = avoidArea1.bottomRect.height;
      // 获取导航条区域
      let avoidArea2 = data.getWindowAvoidArea(type2);
      // 获取到导航条区域的高度
      let indicatorHeight = avoidArea2.bottomRect.height;

      console.info(`导航条的高度 indicatorHeight = ${indicatorHeight}`);
    }).catch((err: BusinessError) => {
      console.error(`获取屏幕顶部状态栏、底部导航栏和导航条的高度 出现异常 Failed to obtain the window. Cause: ${JSON.stringify(err)}`);
    });
  }
