坐标系的转换

百度地图，支持将火星坐标系（高德地图）或者GPS坐标系，转换成百度坐标：

        CoordinateConverter converter = new CoordinateConverter();        converter.from(CoordType.GPS);//GPS-GPS坐标系；COMMON-高德/腾讯/阿里云等火星坐标系        converter.coord(sourceLatLng);        return converter.convert();

高德地图，支持将其他地图坐标系，转成高德坐标系

        CoordinateConverter converter = new CoordinateConverter(context);        converter.from(coordType); //BAIDU,MAPBAR,GPS,MAPABC,SOSOMAP,ALIYUN,GOOGLE;        converter.coord(sourceLatLng);        return converter.convert();
