拍照后保存到本地文件,借助ExifInterface
保存格式必须是JPEG,否则不支持写入编辑
1
| bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fos);
|
写入方法很简单
1 2 3 4 5 6 7 8 9 10 11 12 13
| try { //保存照片的经纬度信息 ExifInterface exif = new ExifInterface(file.getAbsolutePath()); exif.setAttribute(ExifInterface.TAG_GPS_LATITUDE, ConvertUtils.convertToDegree(116.2353515625)); exif.setAttribute(ExifInterface.TAG_GPS_LONGITUDE, ConvertUtils.convertToDegree(39.5379397452)); exif.saveAttributes(); //打印结果 String latValue = exif.getAttribute(ExifInterface.TAG_GPS_LATITUDE); String lngValue = exif.getAttribute(ExifInterface.TAG_GPS_LONGITUDE); Log.i(TAG, "onCameraData: " + ConvertUtils.convertToCoordinate(latValue) + "--" + ConvertUtils.convertToCoordinate(lngValue)); } catch (IOException e) { e.printStackTrace(); }

ConvertUtils 工具类
1 2 3 4 5 6 7 8 9 10 11 12 13 14
| public class ConvertUtils { //经纬度转度分秒 public static String convertToDegree(double gpsInfo) { String dms = Location.convert(gpsInfo, Location.FORMAT_SECONDS); return dms; }
//度分秒转经纬度 public static Double convertToCoordinate(String stringDMS) { if (stringDMS == null) return null; String[] split = stringDMS.split(":", 3); return Double.parseDouble(split[0]) + Double.parseDouble(split[1]) / 60 + Double.parseDouble(split[2]) / 3600; } }

搞定。 最后别忘了文件读写权限
