从2.0.0版本开始，不再支持InfoWindow覆盖物类型，请使用PopView进行信息框开发。

PopView可以通过设置LableUI文本UI，TextStyle文本样式，HorizontalLayout水平布局，VerticalLayout垂直布局，ImageUI设置图像UI，来实现信息框覆盖物的创建。

Marker的 icon图标通过ImageEntity对象设置,通过透明图标作为瞄点，来实现信息框。

import {MapController,Marker,ImageEntity,SysEnum,LabelUI,CommonEvent,TextStyle,PopView} from '@bdmap/map';

mapController: MapController | null = null;
marker: Marker | null = null;
// transparent.png为透明图标
let image = new ImageEntity('rawfile://transparent.png');
this.marker = new Marker({
              position: new LatLng(39.904835, 116.403119),
              icon: image,
              located: SysEnum.Located.CENTER,
              isClickable: false
            });
/** PopView */
{
    let layout = new HorizontalLayout();
    layout.setBackground(new ImageEntity("rawfile://pop_bottom.png"),{
    /** 横向可缩放区域 [x1,x2] or [x1,x2,x3,x4] @since 1.2.0*/
    scaleX: [20,40,100,120],
    /** 纵向可缩放区域 [y1,y2] or [y1,y2,y3,y4]  @since 1.2.0*/
    scaleY: [40,80],
    /**「.9」的内容区域 [x1,x2,y1,y2]  @since 1.2.0*/
    fillArea: [20,120,20,80]
    })
    layout.setBackgroundColor('#ffff')
    layout.setGravity(SysEnum.Gravity.GRAVITY_LEFT);
    let img = new ImageUI();
    img.setDrawableResource(new ImageEntity('rawfile://two.png'));
    img.setWidth(64);
    img.setHeight(64);
    layout.addView(img);
    let label = new LabelUI();
    label.setGravity(SysEnum.Gravity.GRAVITY_CENTER);
    // 提示信息设置
    label.setText("#BmMarker# 百度地图");             
    label.setBackgroundColor('rgba(255,235,59,0.5)')
    label.setPadding(20, 0, 0, 0);
    label.setClickable(false);
    label.addEventListener(CommonEvent.CLICK,(e:EventUIBundle)=>{
    })
    let txtStyle =  new TextStyle();
    txtStyle.setTextColor('rgba(255,0,255,1)');
    txtStyle.setTextSize(28);
    txtStyle.setFontOption(SysEnum.FontOption.BOLD);

    label.setStyle(txtStyle);
    layout.addView(label);
    let popView = this.popView = new PopView();
    popView.setVisibility(SysEnum.Visibility.VISIBLE);
    popView.setView(layout);
    popView.setLocated(SysEnum.Located.CENTER);
    popView.addEventListener(CommonEvent.CLICK,(e:EventUIBundle)=>{
    })
    // 附加PopView
    this.marker?.setPopView(popView);
}
 this.mapController?.addOverlay(this.marker);

InfoWindow 类可以通过设置content纹理资源、position位置点以及yOffset偏移值，实现信息框覆盖物的创建。

可通过ArkUI获取PixelMap，赋值给InfoWindow实现信息框。

@Builder
function RandomBuilder(a:string,b:string) {
    Flex({ direction: FlexDirection.Column, justifyContent: FlexAlign.Center, alignItems: ItemAlign.Center }) {
        Text('Test menu item ' + a)
            .fontSize(20)
            .width(100)
            .height(50)
            .textAlign(TextAlign.Center)
        Divider().color('#00ff00').height(10)
        Text('Test menu item ' + b)
            .fontSize(20)
            .width(100)
            .height(50)
            .textAlign(TextAlign.Center)
    }
    .width(100)
    .height(100)
    .backgroundColor('#ff88')
    .borderRadius(10)
    .id("builder")
}

componentSnapshot.createFromBuilder(()=>{RandomBuilder.bind(this)('ONE','TWO')})
    .then((pixmap: image.PixelMap) => {
        let info = componentUtils.getRectangleById("builder")
        let infoWin = this.infoWin = new InfoWindow({
            anchorX: 0.5,
            anchorY: 0,
            content: new ImageEntity(pixmap,info.size.width,info.size.height)
        })
        infoWin.addEventListener(OverlayEvent.CLICK,()=>{
            promptAction.showToast({
                message: '信息框点击',
                duration: 2000,
            });
        });
        this.marker?.setInfoWindow(infoWin);
    }).catch((err:Error) => {
    console.log("error: " + err)
})

通过直接使用图片纹理的形式赋值给InfoWindow实现信息框。

 let info2 = new InfoWindow({
    position: new LatLng(39.914835, 116.413119),
    content: new ImageEntity('rawfile://info.png'),
    isPerspective: false,
    yOffset: -49
});
info2.addEventListener(OverlayEvent.CLICK,()=>{
    promptAction.showToast({
        message: '信息框点击',
        duration: 2000,
    });
});
this.mapController?.addOverlay(info2);
