【问题描述】:
我正在使用 NativeScript v6 和 Angular 8 编写应用程序。
tns --version 6.1.2
我正在使用这个插件来尝试显示谷歌地图。
地图出现,没有抛出任何错误,但地图是空白的。
这是我的代码 sn-p:
模板
<Page class="page">
<GridLayout rows="auto,*">
<Label row="0" class="h3" text="Maps"></Label>
<MapView
row="1"
#mapView
i-padding="50,50,50,50"
(mapReady)="onMapReady($event)"
iosOverflowSafeArea="true">
</MapView>
</GridLayout>
</Page>
组件
[![import { Component, OnInit } from '@angular/core';
//import { registerElement } from 'nativescript-angular/element-registry';
import { MapView, Marker, Position } from "nativescript-google-maps-sdk";
import { ElementRef, ViewChild } from "@angular/core";
import { registerElement } from "nativescript-angular/element-registry";
// Important - must register MapView plugin in order to use in Angular templates
registerElement('MapView', () => MapView);
@Component({
selector: "ns-clocking",
templateUrl: "./clocking.component.html",
styleUrls: \["./clocking.component.css"\],
moduleId: module.id
})
export class ClockingComponent implements OnInit {
mapView: MapView;
constructor() {}
public ngOnInit() {}
public onMapReady(event) {
console.log(" map ready ");
const mapView = event.object;
this.mapView = mapView;
const NA_CENTER_LATITUDE = 39.8283459;
const NA_CENTER_LONGITUDE = -98.5816737;
this.mapView.latitude = NA_CENTER_LATITUDE;
this.mapView.longitude = NA_CENTER_LONGITUDE;
this.mapView.zoom = 3;
const stLouisCoordinates = {
latitude: 38.619081,
longitude: -90.196846
};
const stLouisMarker = new Marker();
stLouisMarker.position = Position.positionFromLatLng(
stLouisCoordinates.latitude,
stLouisCoordinates.longitude
);
stLouisMarker.title = "St. Louis, MO";
stLouisMarker.snippet = "Go Cardinals!";
stLouisMarker.color = "#6B8E23";
this.mapView.addMarker(stLouisMarker);
}
}
AndroidManifest
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="@string/nativescript_google_maps_api_key" />
我在不同的设置中使用了相同的密钥并且它有效:https://jsfiddle.net/aubz88/6frk9evm/3/
【问题讨论】:

您确定没有对密钥设置任何限制吗?您是否在帐户上启用了 Google 地图服务?
