I have an Android app for searching flights. I want to implement a Google Map where the Origin and the Destination will be shown in the map (with the help of some markers) to the user based on his/her inputs. But before I start anything, I need a help in the overall understanding.
- Which API do I need? Google Maps API or Google Maps Direction API? I don't want to show any direction, only the places marked.
- Is there any HTTP request for Google Maps API? Or how do I dynamically show the places in the map? I will only have the name of the places.
I would really appreciate if somebody can guide me through the initial steps of this implementation.
EDITED:
Below is the Main Activity that I am using:
public class Map_Activity_With_Fragment extends AppCompatActivity implements OnMapReadyCallback {
private GoogleMap googleMap;
String Origin, Destination, Start_Date, Num_Adult, Num_Infant, Origin_Map, Destination_Map;
Context context;
List<Address> Addr_Origin, Addr_Dest;
double latitude_origin, longitude_origin, latitude_destination, longitude_destination;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent intent = getIntent();
Bundle extras = intent.getExtras();
Origin = extras.getString(MainActivity.ORIGIN);
Destination = extras.getString(MainActivity.DESTINATION);
Start_Date = extras.getString(MainActivity.START_DATE);
Num_Adult = extras.getString(MainActivity.ADULT);
Num_Infant = extras.getString(MainActivity.INFANT);
Origin_Map = extras.getString(MainActivity.ORIGIN_MAP);
Destination_Map = extras.getString(MainActivity.DESTINATION_MAP);
context = Map_Activity_With_Fragment.this;
setTitle("Location Map");
setContentView(R.layout.activity_map__with__fragment);
try
{
initializeMap();
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_map__with__fragment, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
@Override
public void onMapReady(GoogleMap googleMap)
{
AddMarkers(googleMap);
}
@Override
protected void onResume() {
super.onResume();
initializeMap();
}
private void initializeMap()
{
if (googleMap == null) {
MapFragment mapFragment = (MapFragment) getFragmentManager().findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}
}
private void AddMarkers(GoogleMap googleMap)
{
try {
Geocoder geocoder = new Geocoder(context);
Addr_Origin = geocoder.getFromLocationName(Origin_Map, 1);
Addr_Dest = geocoder.getFromLocationName(Destination_Map, 1);
if (Addr_Origin.size() > 0) {
latitude_origin = Addr_Origin.get(0).getLatitude();
longitude_origin = Addr_Origin.get(0).getLongitude();
}
if (Addr_Dest.size() > 0) {
latitude_destination = Addr_Dest.get(0).getLatitude();
longitude_destination = Addr_Dest.get(0).getLongitude();
}
Marker m1 = googleMap.addMarker(new MarkerOptions().position(new LatLng(latitude_origin, longitude_origin)).title(Origin_Map));
Marker m2 = googleMap.addMarker(new MarkerOptions().position(new LatLng(latitude_destination, longitude_destination)).title(Destination_Map));
} catch (Exception e) {
e.printStackTrace();
}
}
}
