come cercare l'indirizzo per nome su Google Map Android

Question

Sono un principiante di Android Developer. Sto sviluppando l'applicazione mappa. Ho una funzione di ricerca dell'indirizzo ma non so come cercare l'indirizzo per nome utilizzando l'API di Google Maps V.2. Si prega di suggerire la soluzione e qualche codice per risolvere questo. Grazie mille e mi dispiace con il mio inglese.

Answer 1

protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_search_map); 

     editText = (EditText) findViewById(R.id.editText1); 
     mapView = (MapView) findViewById(R.id.mapView); 
     btngo = (Button) findViewById(R.id.btnmapsites); 

      btngo.setOnClickListener(new View.OnClickListener() {        

      public void onClick(View arg0) { 


     List<Address> addresses; 
     try { 
      addresses = geoCoder.getFromLocationName(editText.getText().toString(),1); 
      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 = mapView.getOverlays(); 
         listOfOverlays.clear(); 
       listOfOverlays.add(mapOverlay); 

        mapView.invalidate(); 
        editText.setText(""); 
      } 
      else 
      { 
        AlertDialog.Builder adb = new AlertDialog.Builder(SearchMapActivity.this); 
        adb.setTitle("Google Map"); 
        adb.setMessage("Please Provide the Proper Place"); 
        adb.setPositiveButton("Close",null); 
        adb.show(); 
      } 

     } catch (IOException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
      } 
      }); 


    }

adderess = c.getString(c.getColumnIndex(SQLiteAdapter.KEY_CONTENT3)); 
// get address in string for used location for the map 

/* get latitude and longitude from the adderress */ 

Geocoder geoCoder = new Geocoder(this, Locale.getDefault()); 
try 
{ 
    List<Address> addresses = geoCoder.getFromLocationName(adderess, 5); 
    if (addresses.size() > 0) 
    { 
     Double lat = (double) (addresses.get(0).getLatitude()); 
     Double lon = (double) (addresses.get(0).getLongitude()); 

     Log.d("lat-long", "" + lat + "......." + lon); 
     final LatLng user = new LatLng(lat, lon); 
     /*used marker for show the location */ 
     Marker hamburg = map.addMarker(new MarkerOptions() 
      .position(user) 
      .title(adderess) 
      .icon(BitmapDescriptorFactory 
      .fromResource(R.drawable.marker))); 
     // Move the camera instantly to hamburg with a zoom of 15. 
     map.moveCamera(CameraUpdateFactory.newLatLngZoom(user, 15)); 

     // Zoom in, animating the camera. 
     map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null); 
    } 
} 
catch (IOException e) 
{ 
    e.printStackTrace(); 
}
