Android: Display User Location On Map Fragment

i am developing an app for my final year exam in android studio and i don't know how to show user location on MapFragment. I've already do this but inside an activity, i need it in

Solution 1:

just add this

@OverridepublicvoidonMapReady(GoogleMap googleMap) {

    MapsInitializer.initialize(getActivity());
    mMap = googleMap;
    mMap.setMyLocationEnabled(true);
    googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
}

to get current location on map.

Solution 2:

Please try this:

In Gradle:

implementation 'gun0912.ted:tedpermission:2.1.0'
implementation 'com.google.android.gms:play-services:12.0.1'

In Fragment:

publicclassHomeextendsFragmentimplementsGoogleApiClient.ConnectionCallbacks,
        GoogleApiClient.OnConnectionFailedListener,
        LocationListener, OnMapReadyCallback {

    private GoogleMap mMap;

    private GoogleApiClient mGoogleApiClient;
    private LocationRequest mLocationRequest;

    private Location locationData;

    privatestaticfinallongTIME_INTERVAL_GET_LOCATION=1000 * 5; // 1 MinuteprivatefinalstaticintCONNECTION_FAILURE_RESOLUTION_REQUEST=5000;

    @Nullable@Overridepublic View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        ViewrootView= inflater.inflate(R.layout.fragment_home, null);

        SupportMapFragmentmapFragment= (SupportMapFragment) getChildFragmentManager()
                .findFragmentById(R.id.map);

        mapFragment.getMapAsync(this);

        TedPermission.with(getActivity())
                .setPermissionListener(permissionlistener)
                .setDeniedMessage("If you reject permission,you can not use this service\n\nPlease turn on permissions at [Setting] > [Permission]")
                .setPermissions(Manifest.permission.ACCESS_FINE_LOCATION)
                .check();

        mGoogleApiClient = newGoogleApiClient.Builder(getActivity())
                .addConnectionCallbacks(this)
