SupportMapFragment mapFragment = SupportMapFragment.newInstance();
mapFragment.getMapAsync(this);
FragmentTransaction transaction = getFragmentManager().beginTransaction();
transaction.replace(R.id.google_map, mapFragment);
transaction.commit();

    mTimeSelect = view.findViewById(R.id.time_options);
    mTimeSelect.setOnItemSelectedListener(new OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
            if (position == 0) {
                mShowType = SHOW_DAILY_TYPE;
            } else {
                mShowType = SHOW_HOURLY_TYPE;
            }
            getResidents();
        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {
        }
    });

    getResidents();

    getCurrentLocation();

    return view;
}

private void getCurrentLocation() {
    mAddress = RestClient.getLoginResident().getAddress();
    AddressLocationUtils.getLocationByAddress(getContext(), RestClient.getLoginResident().getAddress(),
        new IGetLocationCallback() {
            @Override
            public void onGetLocation(double latitude, double longitude) {
                mCurrentLatitude = latitude;
                mCurrentLongitude = longitude;
                showCurrentLocation();
            }
        });
}

private void showCurrentLocation() {
    if (mMap == null) {
        return;
    }
    mHandler.post(new Runnable() {
        @Override
        public void run() {
            LatLng curLocation = new LatLng(mCurrentLatitude, mCurrentLongitude);
            MarkerOptions markerOptions = new MarkerOptions().position(curLocation);
            markerOptions.title("Current Location");
            markerOptions.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_BLUE));
            mMap.addMarker(markerOptions);
            mMap.moveCamera(CameraUpdateFactory.newLatLng(curLocation));
            mMap.animateCamera(CameraUpdateFactory.zoomTo(mMap.getMaxZoomLevel() * 0.8f), 500, null);
        }
    });
