我尝试使用NativeScript和Google maps API包创建带有自定义图标的标记。我将我的图标添加到了android资源中,然后几次构建了我的项目。
np.hstack
即使我尝试使用 var marker = new mapsModule.Marker();
marker.position = mapsModule.Position.positionFromLatLng(result.latitude, result.longitude);
marker.title = "Home";
var icon = new Image();
icon.imageSource = imageSource.fromResource('bot_marker');
marker.icon = icon;
marker.snippet = "This is where I live";
marker.userData = { index: 1 };
mapView.addMarker(marker);
或icon
作为资源,它也不会出现。

使用Angular2
import { Image } from "ui/image";
import { ImageSource } from "image-source";
onMapReady(event) {
console.log("Google map is ready!");
var mapView = event.object;
var marker = new Marker();
marker.position = Position.positionFromLatLng(this.state.latitude, this.state.longitude);
let imgSrc = new ImageSource();
imgSrc.fromResource("pink_pin_dot");
let image = new Image();
image.imageSource = imgSrc;
marker.icon = image;
mapView.addMarker(marker);
}

使用Vue对我有用。
注释1::不推荐使用fromResource
和fromFile
,新功能称为fromFileSync
和fromResourceSync
注释2 :设置图标后请勿更改标记颜色,尽管您已经为自定义图标正确设置了ImageSource,但这将显示默认图标
1)导入所需的NativeScript库
import { Image } from "ui/image";
import { ImageSource } from "image-source";
import { Marker } from "nativescript-google-maps-sdk";
2 a)使用本地路径添加自定义标记图像
const marker = new Marker()
const imageSource = ImageSource.fromFileSync( "~/assets/images/icons/icon.png");
const icon = new Image();
icon.imageSource = imageSource;
marker.icon = icon;
OR
2 b)使用资源添加自定义标记图像(例如,在Android中,这些资源位于app/App_Resources/Android/src/main/res
的可绘制文件夹中,此处的示例图像为icon.png
)
const marker = new Marker()
const imageSource = ImageSource.fromResourceSync("icon");
const icon = new Image();
icon.imageSource = imageSource;
marker.icon = icon;

在 Nativescript 版本 7 中,我使用以下代码使其与本地图像文件一起使用。
import {ImageSource} from "tns-core-modules/image-source";
import { Image } from "tns-core-modules/ui/image";
import {Folder, path, knownFolders} from "tns-core-modules/file-system";
/** Then in the point of adding the marker **/
const folder: Folder = <Folder>knownFolders.currentApp();
const folderPath: string = path.join(folder.path, "images/marker-blue.png");
const imageFromLocalFile: ImageSource = ImageSource.fromFileSync(folderPath);
let image = new Image();
image.imageSource = imageFromLocalFile;
marker.icon = image;
