I want to convert latitude 40.7127837, longitude -74.0059413 and to the following format
N 40°42'46.0218" W 74°0'21.3876"
What is the best way to do that?
I tried methods like location.FORMAT_DEGREES, location.FORMAT_MINUTES and location.FORMAT_SECONDS, but I'm not sure how to convert them to the right format. Thanks.
strLongitude = location.convert(location.getLongitude(), location.FORMAT_DEGREES);
strLatitude = location.convert(location.getLatitude(), location.FORMAT_DEGREES);
The Location.convert()
method that you are using gives very good results and is well implemented and tested. You just need to format the output to suit your needs:
private String convert(double latitude, double longitude) {
StringBuilder builder = new StringBuilder();
if (latitude < 0) {
builder.append("S ");
} else {
builder.append("N ");
}
String latitudeDegrees = Location.convert(Math.abs(latitude), Location.FORMAT_SECONDS);
String[] latitudeSplit = latitudeDegrees.split(":");
builder.append(latitudeSplit[0]);
builder.append("°");
builder.append(latitudeSplit[1]);
builder.append("'");
builder.append(latitudeSplit[2]);
builder.append("\"");
builder.append(" ");
if (longitude < 0) {
builder.append("W ");
} else {
builder.append("E ");
}
String longitudeDegrees = Location.convert(Math.abs(longitude), Location.FORMAT_SECONDS);
String[] longitudeSplit = longitudeDegrees.split(":");
builder.append(longitudeSplit[0]);
builder.append("°");
builder.append(longitudeSplit[1]);
builder.append("'");
builder.append(longitudeSplit[2]);
builder.append("\"");
return builder.toString();
}
When you call this method with your input coordinates:
String locationString = convert(40.7127837, -74.0059413);
You will receive this output:
N 40°42'46.02132" W 74°0'21.38868"
If you're facing problems with the inbuilt methods, you can always create your own method:
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) ;
}
}
