How to implement google maps search by address in Android?

Answer 1

For that you need to create one map overlay class in map activity.

Example

class MapOverlay extends com.google.android.maps.Overlay {     public boolean draw(Canvas canvas, MapView mapView,      boolean shadow, long when)      {         super.draw(canvas, mapView, shadow);                             //---translate the GeoPoint to screen pixels---         Point screenPts = new Point();         mapView.getProjection().toPixels(p, screenPts);          //---add the marker---         Bitmap bmp = BitmapFactory.decodeResource(             getResources(), R.drawable.pink);                     canvas.drawBitmap(bmp, screenPts.x, screenPts.y-32, null);                  return true;     } }  

Where please change R.drawable.pink . Put your any drawable.

Now please write below code in your search onClick event..

Example

List<Address> addresses = geoCoder.getFromLocationName(txtsearch.getText().toString(),5);  if(addresses.size() > 0) {     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();     txtsearch.setText(""); } else {     AlertDialog.Builder adb = new AlertDialog.Builder(GoogleMap.this);     adb.setTitle("Google Map");     adb.setMessage("Please Provide the Proper Place");     adb.setPositiveButton("Close",null);     adb.show(); } 

Where txtsearch is a EditText and controller is a map controller ..
