不需要导入百度地图的SDK，利用手机自带的定位，获取当前的经纬度，然后调用百度地图的地址，返回的为json数据

{status: "OK",result: {location: {lng: 118.776047,lat: 31.965235},formatted_address: "江苏省南京市雨花台区龙西路",business: "铁心桥",addressComponent: {city: "南京市",direction: "",distance: "",district: "雨花台区",province: "江苏省",street: "龙西路",street_number: ""},cityCode: 315}}

//wd 纬度 //jd 经度   public void updateVersion(String wd, String jd) {        String path = "http://api.map.baidu.com/geocoder?output=json&location=" + wd + "," + jd + "&key="这里为你的百度地图的key";        OkHttpUtils                .get()                .url(path)                .build()                .execute(new StringCallback() {                    @Override                    public void onError(Call arg0, Exception arg1, int arg2) {                    }                    @Override                    public void onResponse(String arg0, int arg1) {                        Gson gson = new Gson();                        City response = gson.fromJson(arg0, City.class);                        CMLog.d(TAG, arg0);                        if (response.getStatus().equals("OK")) {                            CMLog.d("地址为", response.getResult().getAddressComponent().getCity());                        }                    }                });    }    public void getLocation() {        String locationProvider;        //获取地理位置管理器        LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);        //获取所有可用的位置提供器        List providers = locationManager.getProviders(true);        if (providers.contains(LocationManager.GPS_PROVIDER)) {            //如果是GPS            locationProvider = LocationManager.GPS_PROVIDER;        } else if (providers.contains(LocationManager.NETWORK_PROVIDER)) {            //如果是Network            locationProvider = LocationManager.NETWORK_PROVIDER;        } else {            Toast.makeText(this, "没有可用的位置提供器", Toast.LENGTH_SHORT).show();            return;        }        //获取Location        Location location = locationManager.getLastKnownLocation(locationProvider);        if (location != null) {            //不为空,显示地理位置经纬度            showLocation(location);        }        //监视地理位置变化        locationManager.requestLocationUpdates(locationProvider, 3000, 1, locationListener);    }    /**     * 显示地理位置经度和纬度信息     *     * @param location     */    private void showLocation(Location location) {        String locationStr = "纬度：" + location.getLatitude() + "\n"                + "经度：" + location.getLongitude();        updateVersion(location.getLatitude() + "", location.getLongitude() + "");    }    /**     * LocationListern监听器     * 参数：地理位置提供器、监听位置变化的时间间隔、位置变化的距离间隔、LocationListener监听器     */    LocationListener locationListener = new LocationListener() {        @Override        public void onStatusChanged(String provider, int status, Bundle arg2) {        }        @Override        public void onProviderEnabled(String provider) {        }        @Override        public void onProviderDisabled(String provider) {        }        @Override        public void onLocationChanged(Location location) {            //如果位置发生变化,重新显示            showLocation(location);        }    };

注意：别忘了加上权限
