I'm trying to put this class in a fragment , how can I make it into a fragment class?
public class MapsActivity extends FragmentActivity {
private GoogleMap mMap; // Might be null if Google Play services APK is not available.
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
setUpMapIfNeeded();
}
@Override
protected void onResume() {
super.onResume();
setUpMapIfNeeded();
}
I need these methods working in my fragment . But I'm not able to drive through the button
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));
}
}
public void onZoom(View view) {
if (view.getId() == R.id.Bzoomin) {
mMap.animateCamera(CameraUpdateFactory.zoomIn());
}
if (view.getId() == R.id.Bzoomout) {
mMap.animateCamera(CameraUpdateFactory.zoomOut());
}
}
public void changeType(View view) {
if (mMap.getMapType() == GoogleMap.MAP_TYPE_NORMAL) {
mMap.setMapType(GoogleMap.MAP_TYPE_SATELLITE);
} else
mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
}
private void setUpMapIfNeeded() {
// Do a null check to confirm that we have not already instantiated the map.
if (mMap == null) {
// Try to obtain the map from the SupportMapFragment.
mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
.getMap();
// Check if we were successful in obtaining the map.
if (mMap != null) {
setUpMap();
}
}
}
All these actions are connected to the layout through " onClick "
private void setUpMap() {
mMap.addMarker(new MarkerOptions().position(new LatLng(0, 0)).title("Marker"));
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// ActivityCompat#requestPermissions
// here to request the missing permissions, and then overriding
// public void onRequestPermissionsResult(int requestCode, String[] permissions,
// int[] grantResults)
// to handle the case where the user grants the permission. See the documentation
// for ActivityCompat#requestPermissions for more details.
return;
}
mMap.setMyLocationEnabled(true);
}
}
what works for me is this
childFragmentManager.fragments[0] as SupportMapFragment?
Let me explain : I have a fragment : Map Fragment and inside it there is an other fragmenr with the map so it is his only child. Be aware that i it is not the best practice but i works for now
class MapFragment : Fragment(), OnMapReadyCallback {
private lateinit var mMap: GoogleMap
override fun onCreateView(
inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
val rootView: View = inflater.inflate(R.layout.fragment_map, container, false)
val mapFragment =
childFragmentManager.fragments[0] as SupportMapFragment?
mapFragment!!.getMapAsync(this)
return rootView
}
override fun onMapReady(googleMap: GoogleMap?) {
mMap = googleMap!!
// Add a marker in Sydney and move the camera
val sydney = LatLng(-34.0, 151.0)
mMap.addMarker(MarkerOptions().position(sydney).title("Marker in Sydney"))
mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney))
}
}
my xml of my fragment is
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".ui.MainActivity">
<fragment
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment" />
</FrameLayout>
Fragment Class should like this...
public MyMapFragment extends Fragment{
private GoogleMap map;
public GoogleApiClient mGoogleApiClient;
private LocationRequest locationRequest;
private Location myLocation;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mGoogleApiClient = new GoogleApiClient.Builder(getActivity()).addConnectionCallbacks(this)
.addOnConnectionFailedListener(this).addApi(LocationServices.API).build();
}
@Override
public void onActivityCreated(Bundle savedInstance) {
super.onActivityCreated(savedInstance);
map = ((MapFragment) act.getFragmentManager()
.findFragmentById(R.id.map)).getMap();
map.getUiSettings().setRotateGesturesEnabled(false);
map.getUiSettings().setZoomControlsEnabled(false);
map.setTrafficEnabled(true);
map.setOnMarkerDragListener(dragListener);
map.setOnMapLongClickListener(longClickListener);
}
@Override
public void onStart() {
super.onStart();
if (mGoogleApiClient != null)
mGoogleApiClient.connect();
}
private void showCurrentLocation(Location location) {
if (map.getCameraPosition().zoom < MAP_ZOOM_LEVEl) {
map.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(
location.getLatitude(), location.getLongitude()), 12));
}
CameraPosition cameraPosition = new CameraPosition(new LatLng(
location.getLatitude(), location.getLongitude()),
map.getCameraPosition().zoom, 45, 360);
map.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));
}
@Override
public void onConnected(@Nullable Bundle bundle) {
if (Build.VERSION.SDK_INT > Build.VERSION_CODES.LOLLIPOP) {
if (ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED
&& ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
return;
}
}
myLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
if (myLocation != null) {
showCurrentLocation(myLocation);
return;
}
if ("Check for GPS Status")
Show the error if not enabled
LocationServices.FusedLocationApi.requestLocationUpdates(
mGoogleApiClient, locationRequest, new LocationListener() {
@Override
public void onLocationChanged(Location location) {
if (location == null)
return;
myLocation = location;
showCurrentLocation(location);
}
});
}
protected void createLocationRequest() {
locationRequest = new LocationRequest();
locationRequest.setFastestInterval(FASTEST_INTERVAL);
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
}
@Override
public void onStop() {
super.onStop();
if (mGoogleApiClient != null && mGoogleApiClient.isConnected())
mGoogleApiClient.disconnect();
}
@Override
public void onDestroyView() {
super.onDestroyView();
MapFragment mapFragment = (MapFragment) getActivity()
.getFragmentManager().findFragmentById(R.id.map);
if (mapFragment != null)
getActivity().getFragmentManager().beginTransaction()
.remove(mapFragment).commit();
}
}
Layout for that fragment
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
In my project, Maps was implemented in the following way:
No meu projeto em implementei o Maps da seguindo maneira:
public class MainFragment extends Fragment implements OnMapReadyCallback {
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_main, container, false);
}
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
MapFragment fragment = (MapFragment) getChildFragmentManager().findFragmentById(R.id.map);
fragment.getMapAsync(this);
} }
