Question

在android（java）中，当你使用函数getlatitude（）等获得当前纬度和经度时，你得到十进制格式的坐标：

纬度：24.3454523经度：10.123450

我想把它变成度数和小数分钟看起来像这样：

纬度：40°42'51“N经度：74°00'21”W

Answer 1

从小数转换为度数，您可以按照以下步骤

String strLongitude = location.convert(location.getLongitude(), location.FORMAT_DEGREES);
String strLatitude = location.convert(location.getLatitude(), location.FORMAT_DEGREES);

参考是android developer site。

修改

我尝试了以下内容并获得输出：

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

根据您的要求尝试不同的选项

Answer 2

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

与-122相同（如果为负值则添加360）

编辑：可能有一些API，我不知道。

Answer 3

如前所述，需要进行一些字符串操作。我创建了以下帮助器类，它将位置转换为DMS格式，并允许指定秒的小数位：

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;
    }
}

Answer 4

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) ;
}

}

Answer 5

这是一个Kotlin版本，改编自Martin Weber的回答。它还设置了正确的半球; N，S，W或E

object LocationConverter {

    fun latitudeAsDMS(latitude: Double, decimalPlace: Int): String {
        val direction = if (latitude > 0) "N" else "S"
        var strLatitude = Location.convert(latitude.absoluteValue, Location.FORMAT_SECONDS)
        strLatitude = replaceDelimiters(strLatitude, decimalPlace)
        strLatitude += " $direction"
        return strLatitude
    }

    fun longitudeAsDMS(longitude: Double, decimalPlace: Int): String {
        val direction = if (longitude > 0) "W" else "E"
        var strLongitude = Location.convert(longitude.absoluteValue, Location.FORMAT_SECONDS)
        strLongitude = replaceDelimiters(strLongitude, decimalPlace)
        strLongitude += " $direction"
        return strLongitude
    }

    private fun replaceDelimiters(str: String, decimalPlace: Int): String {
        var str = str
        str = str.replaceFirst(":".toRegex(), "°")
        str = str.replaceFirst(":".toRegex(), "'")
        val pointIndex = str.indexOf(".")
        val endIndex = pointIndex + 1 + decimalPlace
        if (endIndex < str.length) {
            str = str.substring(0, endIndex)
        }
        str += "\""
        return str
    }
}

Answer 6

我想要类似的东西，在这里和维基百科研究答案之后，发现有一种格式化坐标的标准，ISO 6709#Annex D描述了坐标所需的文本表示形式，考虑到这一点并希望在其中具有可移植且紧凑的实现Kotlin，我以这段代码结束了，希望对其他人有用，

import kotlin.math.abs
import java.util.Locale

// https://en.wikipedia.org/wiki/ISO_6709#Representation_at_the_human_interface_(Annex_D)
fun formatCoordinateISO6709(lat: Double, long: Double, alt: Double? = null) = listOf(
    abs(lat) to if (lat >= 0) "N" else "S", abs(long) to if (long >= 0) "E" else "W"
).joinToString(" ") {
    val degrees = it.first.toInt()
    val minutes = ((it.first - degrees) * 60).toInt()
    val seconds = ((it.first - degrees) * 3600 % 60).toInt()
    "%d°%02d′%02d″%s".format(Locale.US, degrees, minutes, seconds, it.second)
} + (alt?.let { " %s%.1fm".format(Locale.US, if (alt < 0) "−" else "", abs(alt)) } ?: "")

Answer 7

你有一个十进制度的坐标，这种表示格式叫做“DEG”

你想要一个DEG到DMS（度，分，秒）（例如40°42'51“N），
转换。

http://en.wikipedia.org/wiki/Geographic_coordinate_conversion

上的这个java代码实现

如果DEG坐标值是＆lt; 0，经度为西，纬度为南。

Answer 8

使用这个方法并将坐标传递给方法

 private String convertDegMinsSecs(double latitude, double longitude) {
    StringBuilder builder = new StringBuilder();


    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("\"");
    if (latitude < 0) {
        builder.append("S ");
    } else {
        builder.append("N ");
    }

    builder.append("  ");


    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("\"");

    if (longitude < 0) {
        builder.append("W ");
    } else {
        builder.append("E ");
    }

    return builder.toString();
}
