java - 如何处理像 50°3 2'20.548\\\"N"这样的坐标？

Question

我想在我的 Android 项目中实现 map 。我已经准备好 map 、坐标和所有方法，但我发现我不知道如何处理收到的坐标格式:

50°32'20.548\\"N"

Android Studio 需要这样的双格式:-33.852, 151.211……我不知道如何转换它。有没有人处理过类似的问题并可以帮助我？

谢谢:)

我必须使用的坐标(无法更改它们):

{
  "monumentid1": {
    "name": "Bečov nad Teplou - Zámek",
    "gpsx": "50°5'8.145\\\"N",
    "gpsy": "12°50'23.468\\\"E"
  },
  "monumentid2": {
    "name": "Benešov nad Ploučnicí - Zámek ",
    "gpsx": "50°44'32.727\\\"N",
    "gpsy": "14°18'39.412\\\"E"
  },
  "monumentid3": {
    "name": "Bezděz - Hrad",
    "gpsx": "50°32'20.548\\\"N",
    "gpsy": "14°43'11.607\\\"E"

Location类有一个静态方法来执行 DMS 字符串转换(到 double ) - 但首先需要调整字符串以匹配“DD:MM:SS.SSSS”的可接受格式。转换后，符号需要针对半球进行调整:

public class HelloWorld
{
    public static void main(String[] args)
    {
       // The triple backslash is data author's attempt to escape the double-quote.
       String s = "50°32'20.548\\\"N";

       // Get rid of any residual backslashes
       s = s.replace("\\","");

       // split string into constituent parts using apparent separators
       String[] dms = s.split("[°'\"]");

       // form 'newS' which complies with Location.FORMAT_SECONDS
       String newS = dms[0]+":"+dms[1]+":"+dms[2];

       // and grab hemisphere (to implement sign)
       String hemi = dms[3];

       double coord = Location.convert(newS);
       if (hemi.compareTo("W") == 0 || hemi.compareTo("S") == 0) {
           coord = -coord;
       }
   }

}
