在安卓(JAVA)当你)当前的纬度和经度使用功能getlatitude(等你在十进制格式的坐标:如何格式化GPS经纬度?
纬度:24.3454523经度:10.123450
我想进入度和小数分这是这个样子:
北纬:40°42'51“N经度:74°00'21”W

从小数到度CONVER你可以做如下
String strLongitude = location.convert(location.getLongitude(), location.FORMAT_DEGREES);
String strLatitude = location.convert(location.getLatitude(), location.FORMAT_DEGREES);
编辑
我曾尝试下面的事情,得到的输出:
strLongitude = Location.convert(location.getLongitude(), Location.FORMAT_DEGREES);
strLatitude = Location.convert(location.getLatitude(), Location.FORMAT_DEGREES);
OUTPUT : Long: 73.16584: Lat: 22.29924
strLongitude = Location.convert(location.getLongitude(), Location.FORMAT_SECONDS);
strLatitude = Location.convert(location.getLatitude(), Location.FORMAT_SECONDS);
OUTPUT : Long: 73:9:57.03876: Lat: 22:17:57.26472
strLongitude = Location.convert(location.getLongitude(), Location.FORMAT_MINUTES);
strLatitude = Location.convert(location.getLatitude(), Location.FORMAT_MINUTES);
OUTPUT : Long: 73:9.95065: Lat: 22:17.95441
尝试不同的选项,按您的要求
这不起作用。它仍然是十进制格式:/ – user3182266
这对我有效,但我不得不做很多子串才能将格式转换为NSEW格式... – marienke
应该是一些数学:
(int)37.33168 => 37
37.33168 % 1 = 0.33168
0.33168 * 60 = 19.905 => 19
19.905 % 1 = 0.905
0.905 * 60 => 54
用相同-122(添加360如果负值)
编辑:可能有一些API,这我不知道。

Convert Latitude and Longitude Values (Degrees) to Double . Java
你必须以十进制度的坐标,这表示格式被称为“DEG”
而你想要一个DEG到DMS(度,分,秒) (例如40°42'51“N),
转换。
在http://en.wikipedia.org/wiki/Geographic_coordinate_conversion
如果DEG坐标值这个java代码实现< 0,这是西经度或南纬度。
在问题被改进以想要转换成DMS格式后更新了我的答案。 – AlexWien
如前所述,需要一些字符串操作。我创建了下面的辅助类,其位置转换到DMS格式,并允许为秒指定小数位:
import android.location.Location;
import android.support.annotation.NonNull;
public class LocationConverter {
public static String getLatitudeAsDMS(Location location, int decimalPlace){
String strLatitude = Location.convert(location.getLatitude(), Location.FORMAT_SECONDS);
strLatitude = replaceDelimiters(strLatitude, decimalPlace);
strLatitude = strLatitude + " N";
return strLatitude;
}
public static String getLongitudeAsDMS(Location location, int decimalPlace){
String strLongitude = Location.convert(location.getLongitude(), Location.FORMAT_SECONDS);
strLongitude = replaceDelimiters(strLongitude, decimalPlace);
strLongitude = strLongitude + " W";
return strLongitude;
}
@NonNull
private static String replaceDelimiters(String str, int decimalPlace) {
str = str.replaceFirst(":", "°");
str = str.replaceFirst(":", "'");
int pointIndex = str.indexOf(".");
int endIndex = pointIndex + 1 + decimalPlace;
if(endIndex < str.length()) {
str = str.substring(0, endIndex);
}
str = str + "\"";
return str;
}
}
使用此
public static String getFormattedLocationInDegree(double latitude, double longitude) {
try {
int latSeconds = (int) Math.round(latitude * 3600);
int latDegrees = latSeconds/3600;
latSeconds = Math.abs(latSeconds % 3600);
int latMinutes = latSeconds/60;
latSeconds %= 60;
int longSeconds = (int) Math.round(longitude * 3600);
int longDegrees = longSeconds/3600;
longSeconds = Math.abs(longSeconds % 3600);
int longMinutes = longSeconds/60;
longSeconds %= 60;
String latDegree = latDegrees >= 0 ? "N" : "S";
String lonDegrees = longDegrees >= 0 ? "E" : "W";
return Math.abs(latDegrees) + "°" + latMinutes + "'" + latSeconds
+ "\"" + latDegree +" "+ Math.abs(longDegrees) + "°" + longMinutes
+ "'" + longSeconds + "\"" + lonDegrees;
} catch (Exception e) {
return ""+ String.format("%8.5f", latitude) + " "
+ String.format("%8.5f", longitude) ;
}
}
