使用适用于 Android 的 gmaps v2 开始虚拟导览

2022-09-03 15:14:34

有没有办法打开一个虚拟之旅与谷歌地图api v2为Android?(类似于以下内容:https://www.google.com/maps/@37.772031,-122.432005,3a,75y,12.85h,79.63t/data=!3m5!1e1!3m3!1srR8mp3c5XZoAAAAGOphoBg!2e0!3e2 )

我想点击gmap中的一个地方,并提供打开虚拟游览的可能性(除其他信息外)(即使在网络视图中,但我如何创建上述链接?

Photo Sphere 是一项 Android 相机功能,可让您创建身临其境的 360 度全景图,类似于街景视图。您可以拍摄一系列照片,并自动将它们转换为无缝的360度全景图。然后,您可以轻松地与Google地图共享您的照片球体。

enter image description here

为了让 Google 地图显示在您的 App 中,您应该将其包含在您的活动中:

MainActivity.java
public class MainActivity extends Activity {

    // Google Map
    private GoogleMap googleMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        try {
            // Loading map
            initilizeMap();

        } catch (Exception e) {
            e.printStackTrace();
        }

    }

    /**
     * function to load map. If map is not created it will create it for you
     * */
    private void initilizeMap() {
        if (googleMap == null) {
            googleMap = ((MapFragment) getFragmentManager().findFragmentById(
                    R.id.map)).getMap();

            // check if map is created successfully or not
            if (googleMap == null) {
                Toast.makeText(getApplicationContext(),
                        "Sorry! unable to create maps", Toast.LENGTH_SHORT)
                        .show();
            }
        }
    }

    @Override
    protected void onResume() {
        super.onResume();
        initilizeMap();
    }

}

enter image description here

并且还在代码中包含要打开虚拟游览的位置的标记

// latitude and longitude
double latitude = ;
double longitude = ;

// create marker
MarkerOptions marker = new MarkerOptions().position(new LatLng(latitude, longitude)).title("Hello Maps ");

// adding marker
googleMap.addMarker(marker);

enter image description here

然后更新它以相应地与提供的当前位置坐标进行交互:

 public boolean onMarkerClick(Marker marker) {

  if(markerClicked){

   if(polyline != null){
    polyline.remove();
    polyline = null;
   }

   rectOptions.add(marker.getPosition());
   rectOptions.color(Color.RED);
   polyline = myMap.addPolyline(rectOptions);
  }else{
   if(polyline != null){
    polyline.remove();
    polyline = null;
   }

   rectOptions = new PolylineOptions().add(marker.getPosition());
   markerClicked = true;
  }

  return true;
 }

}

enter image description here

一旦照片球体被制作成开放格式,任何人都可以在网络或移动设备上创建和查看它们,只需要使用Panorama Class/Interface即可:

// This listener will be called with information about the given panorama.
OnPanoramaInfoLoadedListener infoLoadedListener =
  new OnPanoramaInfoLoadedListener() {
    @Override
    public void onPanoramaInfoLoaded(ConnectionResult result,
                                     Intent viewerIntent) {
        if (result.isSuccess()) {
            // If the intent is not null, the image can be shown as a
            // panorama.
            if (viewerIntent != null) {
                // Use the given intent to start the panorama viewer.
                startActivity(viewerIntent);
            }
        }

        // If viewerIntent is null, the image is not a viewable panorama.
    }
};

// Create client instance and connect to it.
PanoramaClient client = ...
...

// Once connected to the client, initiate the asynchronous check on whether
// the image is a viewable panorama.
client.loadPanoramaInfo(infoLoadedListener, panoramaUri);

enter image description here

这将允许您将照片球查看器作为应用程序的一部分。
