                mLocationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
                mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0,
                        0, mLocationListener);
                Criteria mCriteria = new Criteria();
                String bestProvider = String.valueOf(mLocationManager.getBestProvider(mCriteria, true));
                Location mLocation = mLocationManager.getLastKnownLocation(bestProvider);
                if (mLocation != null) {
                    Log.e("TAG", "GPS is on");
                    final double currentLatitude = mLocation.getLatitude();
                    final double currentLongitude = mLocation.getLongitude();
                    LatLng loc1 = new LatLng(currentLatitude, currentLongitude);

                    mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(currentLatitude, currentLongitude), 10));
                    mMap.animateCamera(CameraUpdateFactory.zoomTo(10), 1000, null);

推荐答案

protected synchronized void buildGoogleApiClient() {
    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .addApi(LocationServices.API)
            .build();

    mGoogleApiClient.connect();
}

mLastLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);

CameraPosition cameraPosition = new CameraPosition.Builder()
            .target(new LatLng(mLastLocation.getLatitude(), mLastLocation.getLongitude()))
            .zoom(10)
            .bearing(0.0f)
            .tilt(00.0f)
            .build();
    map.moveCamera(CameraUpdateFactory
            .newCameraPosition(cameraPosition));
