在 ng2-TNS-Android 整體就緒示例中使用 surfaceView

app.component.ts：

import {Component,OnInit} from "@angular/core";
import placeholder = require("ui/placeholder");
let application= require("application");

@Component({
    selector: "my-app",
    templateUrl: "app.component.html",
})
export class AppComponent implements OnInit{

  public creatingView(args: any) {
    var nativeView = new android.view.SurfaceView(application.android.currentContext);
    args.view = nativeView;
  }

  onLoaded(element){
    let mSurface = element.android;
    let holder =  mSurface.getHolder();
  }

  public init: boolean = false;
    ngOnInit() {
        this.init = true;
    }
}

app.component.html：

<StackLayout>
   <Placeholder  #surface *ngIf="init" (creatingView)="creatingView($event)" (loaded)="onLoaded(surface)"></Placeholder>
</StackLayout>
