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。
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();
}
}
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);
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;
}
}
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);
这将允许您将照片球查看器作为应用程序的一部分。
