Android 得到照片位置信息
目前Android SDK定义的Tag有: TAG_DATETIME时间日期 TAG_FLASH闪光灯 TAG_GPS_LATITUDE纬度 TAG_GPS_LATITUDE_REF纬度参考 TAG_GPS_LONGITUDE经度 TAG_GPS_LONGITUDE_REF经度参考 TAG_IMAGE_LENGTH图片长 TAG_IMAGE_WIDTH图片宽 TAG_MAKE设备制造商 TAG_MODEL设备型号 TAG_ORIENTATION方向 TAG_WHITE_BALANCE白平衡 String sFileName="/sdcard/DCIM/Camera/1.JPG"; try{ ExifInterface exif = new ExifInterface(sFileName); String sModel=exif.getAttribute(ExifInterface.TAG_MODEL); Toast.makeText(PhotoCatActivity.this,"1.JPG Exif:"+sModel, Toast.LENGTH_SHORT).show(); } catch(Exception ee){ } 经纬度得到的数据格式是 "num1/denom1,num2/denom2,num3/denom3"，如何得到真正的经纬度呢？ public Location exif2Loc(String flNm) { String sLat = "", sLatR = "", sLon = "", sLonR = ""; try { ExifInterface ef = new ExifInterface(flNm); sLat = ef.getAttribute(ExifInterface.TAG_GPS_LATITUDE); sLon = ef.getAttribute(ExifInterface.TAG_GPS_LONGITUDE); sLatR = ef.getAttribute(ExifInterface.TAG_GPS_LATITUDE_REF); sLonR = ef.getAttribute(ExifInterface.TAG_GPS_LONGITUDE_REF); } catch (IOException e) {return null;} double lat = dms2Dbl(sLat); if (lat > 180.0) return null; double lon = dms2Dbl(sLon); if (lon > 180.0) return null; lat = sLatR.contains("S") ? -lat : lat; lon = sLonR.contains("W") ? -lon : lon; Location loc = new Location("exif"); loc.setLatitude(lat); loc.setLongitude(lon); return loc; } //------------------------------------------------------------------------- double dms2Dbl(String sDMS){ double dRV = 999.0; try { String[] DMSs = sDMS.split(",", 3); String s[] = DMSs[0].split("/", 2); dRV = (new Double(s[0])/new Double(s[1])); s = DMSs[1].split("/", 2); dRV += ((new Double(s[0])/new Double(s[1]))/60); s = DMSs[2].split("/", 2); dRV += ((new Double(s[0])/new Double(s[1]))/3600); } catch (Exception e) {} return dRV; } 如何根据经纬度得到具体的地址？ public final String getAddress(double latitude, double longitude) { Geocoder gc = new Geocoder(this, Locale.getDefault()); StringBuilder sb = new StringBuilder(); try { List add = gc.getFromLocation(latitude, longitude, 1); if (add.size() > 0) { Address ad = add.get(0); sb.append(ad.getAddressLine(0)); sb.append(ad.getAddressLine(1)); sb.append(ad.getAddressLine(2)); } } catch (Exception e) { } return sb.toString(); } 本文转自 netcorner 博客园博客，原文链接： http://www.cnblogs.com/netcorner/p/7279984.html ，如需转载请自行联系原作者
