使用 Angular 2 连接 Google Maps Nativescript 插件 [英] Wiring up Google Maps Nativescript plugin with Angular 2

问题描述

我正在尝试将 Google 地图插件用于 Nativescript (https://github.com/dapriett/nativescript-google-maps-sdk) 与 Angular 2 和 {N}-Angular 路由器.我只在 Nativescript 中使用它，但是一旦我添加了 Angular 2 和路由器，我就无法让地图显示在 UI 中.

I'm trying to use the Google Maps plugin for Nativescript (https://github.com/dapriett/nativescript-google-maps-sdk) with Angular 2 and the {N}-Angular router. I have it working in just Nativescript but once I add in Angular 2 and the router I'm failing to get the map to show up in the UI.

由于 标签没有进入 Angular2 {N} 组件模板，我不能使用 xmlns:maps="nativescript-google-maps- 上的 sdk" 命名空间，用于实例化

Since a <Page> tag doesn't go into an Angular2 {N} component template, I can't use the xmlns:maps="nativescript-google-maps-sdk" namespace on the <Page> to instantiate the <maps:mapView>

{N} 组件基础页面提供了一些指导，但它在我尝试过的方式中不起作用:https://docs.nativescript.org/ui/ui-with-xml#user-interface-components

The {N} component basics page gives some guidance but it doesn't work in the ways I've tried: https://docs.nativescript.org/ui/ui-with-xml#user-interface-components

知道正确的方法吗?

app.component.ts

app.component.ts

import {Component} from "angular2/core";
import {RouteConfig} from "angular2/router";
import {NS_ROUTER_DIRECTIVES, NS_ROUTER_PROVIDERS} from "nativescript-angular/router";
import {HomeComponent} from "./pages/home/home.component";

@Component({
    selector: "app-main",
    directives: [NS_ROUTER_DIRECTIVES],
    providers: [NS_ROUTER_PROVIDERS],
    template: "<page-router-outlet ></page-router-outlet>"
})
@RouteConfig([
    { path: "/home", component: HomeComponent, as: "Home", useAsDefault: true },
])
export class AppComponent {
}

home.html

<stack-layout orientation="vertical">
    <label [text]="message"></label>
    <mapView [latitude]="latitude" [longitude]="longitude"
                  [zoom]="zoom" [bearing]="bearing"
                  [tilt]="tilt" (mapReady)="OnMapReady"
                  (markerSelect)="onMarkerSelect"
                  (cameraChanged)="onCameraChanged">
    </mapView>
</stack-layout>

home.component.ts

home.component.ts

import {Component} from "angular2/core";
var geolocation = require("nativescript-geolocation");
var mapsModule = require("nativescript-google-maps-sdk");
exports.mapView = mapsModule.MapView; //Doesn't work
exports.mapView = new mapsModule.MapView(); //Doesn't work
exports.mapView = mapsModule; //Doesn't work

@Component({
    selector: "home",
    templateUrl: "pages/home/home.html",
})
export class HomeComponent {
    public message:string = "Message set.";
    public latitude:number = 30.0;
    public longitude:number = -100.0;
    public zoom:number = 10;
    public bearing:number = 0;
    public tilt:number = 0;

    constructor() {
        this.message = "Home constructed.";
    }
    OnMapReady(args) { }
    onMarkerSelect(args) { }
    onCameraChanged(args) { }
}

推荐答案

您需要使用 element-registry API 注册 mapView 标签名称，例如:

You need to register the mapView tag name with the element-registry API e.g.:

https://github.com/NativeScript/nativescript-angular/blob/master/src/nativescript-angular/element-registry.ts#L70-L105

该 API 尚未记录在案，但我们应该在未来几周内解决该问题.

That API isn't documented yet, but we should fix that problem in the coming weeks.
