使用Android 原生 API获取经纬度并且根据经纬度解析出当前具体位置信息

1.动态获取经纬度权限

2.获取经纬度：根据 LocationManager  NETWORK_PROVIDER，GPS_PROVIDER，PASSIVE_PROVIDER 去获取

  public static void getLocation(final ICallback callback) {
        if (ActivityCompat.checkSelfPermission(CCApplication.getInstance(), Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED
                && ActivityCompat.checkSelfPermission(CCApplication.getInstance(), Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            if (callback != null) {
                callback.onError(new Throwable("no permission"));
            }
            return;
        }
        String mLocationProvider;
        final LocationManager locationManager = (LocationManager) CCApplication.getInstance().getSystemService(Context.LOCATION_SERVICE);
        if (locationManager == null) {
            if (callback != null) {
                callback.onError(new Throwable("locationManager null"));
            }
            return;
        }
        List providers = locationManager.getProviders(true);
        LocationListener locationListener = new LocationListener() {
            @Override
            public void onLocationChanged(Location location) {
//                updateLocation(location, callback);
            }

            @Override
            public void onStatusChanged(String provider, int status, Bundle extras) {

            }

            @Override
            public void onProviderEnabled(String provider) {

            }

            @Override
            public void onProviderDisabled(String provider) {

            }
        };
        if (providers == null || providers.isEmpty()) {
            if (callback != null) {
                callback.onError(new Throwable("providers null"));
            }
            return;
        }
        if (providers.contains(LocationManager.NETWORK_PROVIDER)) {
            locationManager.requestSingleUpdate(LocationManager.NETWORK_PROVIDER, locationListener, null);
            mLocationProvider = LocationManager.NETWORK_PROVIDER;
        } else if (providers.contains(LocationManager.GPS_PROVIDER)) {
            locationManager.requestSingleUpdate(LocationManager.GPS_PROVIDER, locationListener, null);
            mLocationProvider = LocationManager.GPS_PROVIDER;
        } else if (providers.contains(LocationManager.PASSIVE_PROVIDER)) {
            locationManager.requestSingleUpdate(LocationManager.PASSIVE_PROVIDER, locationListener, null);
            mLocationProvider = LocationManager.PASSIVE_PROVIDER;
        } else {
            if (callback != null) {
                callback.onError(new Throwable("providers contains null"));
            }
            return;
        }
        Location location = locationManager.getLastKnownLocation(mLocationProvider);
        updateLocation(location, callback);
    }

    public static void updateLocation(Location location, final ICallback callback) {
        if (location == null) {
            if (callback != null) {
                callback.onError(new Throwable("location null"));
            }
            return;
        }
        double latitude = location.getLatitude();
        double longitude = location.getLongitude();
        Log.i(TAG, "latitude : " + latitude + "  longitude : " + longitude);
        getAddress(latitude, longitude, callback);
    }

3.根据经纬度去解析具体位置：主要是Geocoder-->getFromLocation

  public static void getAddress(double latitude, double longitude, final ICallback callback) {
        Geocoder geocoder = new Geocoder(CCApplication.getInstance(), Locale.ENGLISH);
        try {
            List addresses = geocoder.getFromLocation(latitude, longitude, 1);
            Address address = addresses != null && addresses.size() > 0 ? addresses.get(0) : null;
            if (address != null) {
                String countryName = address.getCountryName();
                String countryCode = address.getCountryCode();
                Log.i(TAG, "countryName : " + countryName + "  countryCode : " + countryCode);
                if (callback != null) {
                    callback.onResult(new LocationBean(latitude, longitude, countryName, countryCode, address.toString()));
                }
            } else {
                if (callback != null) {
                    callback.onError(new Throwable("address null"));
                }
            }
        } catch (IOException e) {
            e.printStackTrace();
            if (callback != null) {
                callback.onError(e);
            }
        }
    }

4.最终结果：
