android-如何在osmdroid中添加卫星图像

Question

I get a .png from my server that represents a satellite image and I would put this image like a layer over the OpenStreetMap so I can see the street (under the satellite image) and the aerial photo on the same map.

I use this method

    Drawable d = new BitmapDrawable(getResources(), bitmap);
    bb = map.getBoundingBox();

    Location SO = new Location(LocationManager.GPS_PROVIDER);
    SO.setLatitude(bb.getLonWest());
    SO.setLongitude(bb.getLatSouth());

    Location NO = new Location(LocationManager.GPS_PROVIDER);
    NO.setLatitude( bb.getLonWest());
    NO.setLongitude(bb.getLatNorth());

    Location NE = new Location(LocationManager.GPS_PROVIDER);
    NE.setLatitude(bb.getLonEast());
    NE.setLongitude(bb.getLatNorth());

    float height = SO.distanceTo(NO);
    float width = NE.distanceTo(NO);

    Projection projection = map.getProjection();
    int y = map.getHeight() / 2;
    int x = map.getWidth() / 2;
    GeoPoint geoPoint = (GeoPoint) projection.fromPixels(x, y);

    deleteLayers(GroundOverlay.class);
    GroundOverlay myGroundOverlay = new GroundOverlay();

    myGroundOverlay.setImage(d);
    myGroundOverlay.setPosition(geoPoint);
    myGroundOverlay.setDimensions(width*0.94f,  height*1.06f);
    map.getOverlays().add(myGroundOverlay);
    map.invalidate();

the problem is that the image always is stretch. my png cover only a part of my map (and it's ok beacuse our png is this way). When i move in the map the image stretching in all map but and it cover a part of map that it not rappresent. Also, the image is not in the right place (look the red arrow).

How can i fix it?

Answer 1

假设您的卫星图像仅限于地图的一部分，则可以使用osmbonuspack GroundOverlay。
