My app displays a map, and automatically takes user to their current location. There is a text box that allows the users to type their location to display a marker at the address typed on the text bar.
When I start the app, it correctly shows the user where they are located. When I type a new address on the map, it shows a marker at the newly typed location. However, after this it automatically takes the user back to where they are located and removes the marker from the user typed location.
I suppose the onLocationChnaged fires multiple times. Does anyone know what's the solution to find the user location just once when the app is started?
This is my code:
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
if (view != null)
{
ViewGroup parent = (ViewGroup) view.getParent();
if (parent != null)
parent.removeView(view); }
try
{
view = inflater.inflate(R.layout.fragment_map_view, container, false);
}
catch (InflateException e)
{ /* map is already there, just return view as it is */ }
LocationManager lm = (LocationManager)getActivity().getSystemService(Context.LOCATION_SERVICE);
lm.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, this);
map = ((SupportMapFragment)getFragmentManager().findFragmentById(R.id.map_fragment)).getMap();
map.setMyLocationEnabled(true);
FragmentManager fm = getFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
DateTimeFragment datetime=new DateTimeFragment();
ft.add(R.id.datetime_container_map, datetime);
//SupportMapFragment mapFragment=null;
//if(mapFragment==null)
// mapFragment= (SupportMapFragment)fm.findFragmentById(R.id.map_fragment);
ft.commit();

category.setOnItemSelectedListener(this);
return view;
}
public void onItemClick(AdapterView<?> adapterView, View view, int position, long id)
{
String address_text = (String) adapterView.getItemAtPosition(position);
Geocoder geocoder = new Geocoder(getActivity().getBaseContext());
List<Address> addresses=null;
LatLng latlng;

try {
// Getting a maximum of 3 Address that matches the input text

} catch (IOException e) {
e.printStackTrace();
}
if(addresses==null || addresses.size()==0){
Toast.makeText(getActivity().getBaseContext(), "No Location found", Toast.LENGTH_SHORT).show();
}
// Clears all the existing markers on the map
map.clear();
// Adding Markers on Google Map for each matching address
for(int i=0;i<addresses.size();i++){

// Creating an instance of GeoPoint, to display in Google Map
latlng = new LatLng(address.getLatitude(), address.getLongitude());
String addressText = String.format("%s, %s",
address.getMaxAddressLineIndex() > 0 ? address.getAddressLine(0) : "",
address.getCountryName());
markerOptions = new MarkerOptions();
markerOptions.position(latlng);
markerOptions.title(addressText);
map.addMarker(markerOptions);
// Locate the first location
if(i==0)
map.animateCamera(CameraUpdateFactory.newLatLng(latlng));
}
}
#Override
public void onLocationChanged(Location location) {
map.clear();
MarkerOptions mp = new MarkerOptions();
mp.position(new LatLng(location.getLatitude(), location.getLongitude()));
mp.title("my position");
map.addMarker(mp);
map.animateCamera(CameraUpdateFactory.newLatLngZoom(

Does anyone know why after displaying the marker in the user typed address, the marker is automatically updated to the user location?
PS: I also wanted to know on a side note, if it is a good practice to convert string to address using Geocoder as shown..or should I be placing this inside an AsyncTask
Could it be that your onLocationChanged() is firing and updating the marker to the current location?
You can guard against multiple updates:
private Location mLocation = null;
#Override
public void onLocationChanged(Location location) {
if (mLocation == null) {
mLocation = location;
map.clear();
MarkerOptions mp = new MarkerOptions();
mp.position(new LatLng(location.getLatitude(), location.getLongitude()));
mp.title("my position");
map.addMarker(mp);
map.animateCamera(CameraUpdateFactory.newLatLngZoom(
new LatLng(location.getLatitude(), location.getLongitude()), 16));
}
}

How can I turn this method to be used in a fragment class? I am unable to use this method in a fragment (onCreate).
public void onSearch(View view) {
EditText location_tf = (EditText) findViewById(R.id.TFaddress);
String location = location_tf.getText().toString();
List<Address> addressList = null;
if (location != null || !location.equals("")) {
Geocoder geocoder = new Geocoder(this);
try {
addressList = geocoder.getFromLocationName(location, 1);
} catch (IOException e) {
e.printStackTrace();
}
Address address = addressList.get(0);
LatLng latLng = new LatLng(address.getLatitude(), address.getLongitude());
mMap.addMarker(new MarkerOptions().position(latLng).title("Marker"));
mMap.animateCamera(CameraUpdateFactory.newLatLng(latLng));
}
}
I do not know how the inclusion of an action through this method onSearch , the layout is ready to receive the method but do not know how to insert it in the class. I 'm trying to insert the onSearch method in this code :
public class FragmentC extends Fragment{
MapView mMapView;
private GoogleMap googleMap;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// inflat and return the layout
View v = inflater.inflate(R.layout.frag4, container,
false);
mMapView = (MapView) v.findViewById(R.id.map);
mMapView.onCreate(savedInstanceState);
mMapView.onResume();// needed to get the map to display immediately
try {
MapsInitializer.initialize(getActivity().getApplicationContext());
} catch (Exception e) {
e.printStackTrace();
}
googleMap = mMapView.getMap();
// latitude and longitude
double latitude = 17.385044;
double longitude = 78.486671;
// create marker
MarkerOptions marker = new MarkerOptions().position(
new LatLng(latitude, longitude)).title("Hello Maps");
// Changing marker icon
marker.icon(BitmapDescriptorFactory
.defaultMarker(BitmapDescriptorFactory.HUE_ROSE));
// adding marker
googleMap.addMarker(marker);
CameraPosition cameraPosition = new CameraPosition.Builder()
.target(new LatLng(17.385044, 78.486671)).zoom(12).build();
googleMap.animateCamera(CameraUpdateFactory
.newCameraPosition(cameraPosition));
// Perform any camera updates here
return v;
}
#Override
public void onResume() {
super.onResume();
mMapView.onResume();
}
#Override
public void onPause() {
super.onPause();
mMapView.onPause();
}
#Override

// Log.d(TAG, "onDestroyView");
Fragment f = getActivity()
.getSupportFragmentManager().findFragmentById(R.id.map);
if (f != null) {
getActivity().getSupportFragmentManager()
.beginTransaction().remove(f).commit();
}
}
#Override

mMapView.onLowMemory();
}
Assuming that mMapView is the same as mMap, and that theres a button that triggers the onSearch method, here's how your Fragment code should look like. Pay attention to the onCreateView changes and that the method onSearch does not recieves a View param:
private EditText mLocationEditText;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// inflat and return the layout
View v = inflater.inflate(R.layout.frag4, container,
false);
mMapView = (MapView) v.findViewById(R.id.map);
mMapView.onCreate(savedInstanceState);
mMapView.onResume();// needed to get the map to display immediately
// Obtain the EditText view reference first
mLocationEditText = (EditText) v.findViewById(R.id.TFaddress);
// Obtain the button that triggers the onSearch reference
mButtonThatTriggersSearch = (Button) v..findViewById(R.id.search_button_id);
// Set the onClickListener that should excecute when someome clicks the button
mButtonThatTriggersSearch.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Perform action on click
onSearch();
}
});
try {
MapsInitializer.initialize(getActivity().getApplicationContext());
} catch (Exception e) {
e.printStackTrace();
}
googleMap = mMapView.getMap();
// latitude and longitude
double latitude = 17.385044;
double longitude = 78.486671;
// create marker
MarkerOptions marker = new MarkerOptions().position(
new LatLng(latitude, longitude)).title("Hello Maps");
// Changing marker icon
marker.icon(BitmapDescriptorFactory
.defaultMarker(BitmapDescriptorFactory.HUE_ROSE));
// adding marker
googleMap.addMarker(marker);
CameraPosition cameraPosition = new CameraPosition.Builder()
.target(new LatLng(17.385044, 78.486671)).zoom(12).build();
googleMap.animateCamera(CameraUpdateFactory
.newCameraPosition(cameraPosition));
// Perform any camera updates here
return v;
}
private void onSearch() {
String location = mLocationEditText.getText().toString();
List<Address> addressList = null;
if (location != null || !location.equals("")) {
Geocoder geocoder = new Geocoder(getActivity());
try {
addressList = geocoder.getFromLocationName(location, 1);
} catch (IOException e) {
e.printStackTrace();
}
Address address = addressList.get(0);
LatLng latLng = new LatLng(address.getLatitude(), address.getLongitude());
mLocationEditText.addMarker(new MarkerOptions().position(latLng).title("Marker"));
mLocationEditText.animateCamera(CameraUpdateFactory.newLatLng(latLng));
}
}
I want to add marker on map with long click. but it is not working. normal click is working.

How can i solve this ?
In onCreate
googleMap.setOnMapLongClickListener(longClickListener);
Inside the activity
private OnMapLongClickListener longClickListener = new OnMapLongClickListener() {
#Override

//do work }
}

May be here is problem
LatLng pinLocation = new LatLng(Float.valueOf(map.get("longi")),Float.valueOf(map.get("longi")));"
you have used "longi" in (map.get("longi") for both Latitute and Longitude

Delete markers using
googleHarita.clear()
https://developer.android.com/reference/com/google/android/gms/maps/GoogleMap.html#clear()
Just one call to this method should be enough to remove all the markers on your map.
Then, and add markers using
googleHarita.addMarker()
http://developer.android.com/reference/com/google/android/gms/maps/model/Marker.html
example here
I don't think you need to refresh any pages.
You have to use map.clear(); which will help you to removes all markers, polylines, polygons, overlays, etc from the map.
I am making a demo app with Google Maps Api V2.
I have added a simple marker and I have made it draggable
Here is my code:
onCreate method()
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.demo_v2);
googleMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
googleMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
googleMap.setOnMapClickListener(this);
googleMap.setOnMarkerDragListener(this);
googleMap.setOnMapLongClickListener(this);
set info method()
googleMap.setInfoWindowAdapter(new InfoWindowAdapter() {
#Override
public View getInfoWindow(Marker arg0) {
return null;
}
#Override
public View getInfoContents(Marker marker) {
LayoutInflater inflater = (LayoutInflater) MapsDemo.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = inflater.inflate(R.layout.custom_info, null);
TextView tv = (TextView) v.findViewById(R.id.textView1);
tv.setText(marker.getSnippet());
return v;
}
});
googleMap.setMyLocationEnabled(true);
googleMap.getUiSettings().setRotateGesturesEnabled(true);
googleMap.getUiSettings().setTiltGesturesEnabled(true);
addMarker method
marker = googleMap.addMarker(new MarkerOptions()
.position(ROMA)
.title("Hello")
.snippet("Nice Place")
.icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_launcher))
.draggable(true));
#Override
public void onMarkerDrag(Marker marker) {
// TODO Auto-generated method stub
}
#Override
public void onMarkerDragEnd(Marker marker) {
LatLng field = marker.getPosition();
System.out.println("LatitudenLongitude:" + field.latitude + " " + field.longitude);
}
#Override
public void onMarkerDragStart(Marker marker) {
// TODO Auto-generated method stub
}
#Override
public void onMapLongClick(LatLng latlng) {
// TODO Auto-generated method stub
}
#Override
public void onMapClick(LatLng latlng) {
// TODO Auto-generated method stub
}
}
Now I want the address to come out when the user clicks on the marker.
Simple question is : How to get the address( name) from Lat Long in API v2?
Try this:
public List<Address> getAddress() {
if (latitude != 0 && longitude != 0) {
try {
Geocoder geocoder = new Geocoder(context);
List<Address> addresses = geocoder.getFromLocation(latitude, longitude, 1);
String address = addresses.get(0).getAddressLine(0);
String city = addresses.get(0).getAddressLine(1);
String country = addresses.get(0).getAddressLine(2);
Log.d("TAG", "address = " + address + ", city = " + city + ", country = " + country);
} catch (Exception e) {
e.printStackTrace();
}
} else {
Toast.makeText(context, "latitude and longitude are null", Toast.LENGTH_LONG).show();
}
return addresses;
}
You should use the Geocoder available in the Android API. You will need to make a call to getFromLocation(latitude,longitude,maxResults) which will return a List<Address>.
