jak wyszukiwać adres według nazwy na Google Map Android

Question

Jestem początkującym programistą Androida. Opracowuję aplikację Map. Mam funkcję wyszukiwania adresu, ale nie wiem, jak wyszukiwać adres według nazwy za pomocą interfejsu Google Map API V.2. Proszę, zasugeruj mi rozwiązanie i kod do rozwiązania tego problemu. Dziękuję bardzo i przepraszam z moim angielskim.

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(); 
}
