How to implement google maps to search by street name, city? - google-maps

Question

I need search functionality like this site. But I am wondering how can I get coordinates from google api by street name?

Answer 1

Google Geocoding API
You can enter in an address and it will return the Lat/long co-ordinates in a Json response or XML etc
You can read about it here:

Answer 2

In the onclick event of search write
List<Address> addresses = geoCoder.getFromLocationName("enter location name",5);
p = new GeoPoint( (int) (addresses.get(0).getLatitude() * 1E6),
(int) (addresses.get(0).getLongitude() * 1E6));
controller.animateTo(p);
controller.setZoom(12);
MapOverlay mapOverlay = new MapOverlay();
List<Overlay> listOfOverlays = map.getOverlays();
listOfOverlays.clear();
listOfOverlays.add(mapOverlay);
map.invalidate();
Then create map overlay class in mapActivity
class MapOverlay extends Overlay
{
private GeoPoint pointToDraw;
public void setPointToDraw(GeoPoint point) {
pointToDraw = point;
}
public GeoPoint getPointToDraw()
{
return pointToDraw;
}
#Override
public boolean draw(Canvas canvas, MapView mapView, boolean shadow, long when) {
super.draw(canvas, mapView, shadow);
// convert point to pixels
Point screenPts = new Point();
mapView.getProjection().toPixels(pointToDraw, screenPts);
// add marker
Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.marker);
canvas.drawBitmap(bmp, screenPts.x, screenPts.y - 24, null); // 24 is the height of image
return true;
}
}
