android - java : Convert Location into String and back

Question

对于 android Room，我需要一个类型转换器来保存 Location 对象。将位置转换为字符串相当简单，例如:

public static String locationStringFromLocation(final Location location) {
        if (location==null) return "Location was null";
        return Location.convert(location.getLatitude(), Location.FORMAT_DEGREES) + " " + Location.convert(location.getLongitude(), Location.FORMAT_DEGREES);
    }

但反过来似乎就不那么明显了。我可以附加所有属性并用分隔符分隔它们，但这似乎不太优雅。任何想法将不胜感激。

我当前的解决方法是仅保存纬度和经度，但我更愿意拥有该对象。

public static Location locationFromString(String location){
    if (location != null && (location.contains(","))) {
        Location result = new Location("Generated_location");
        String[] locationStrings = location.split(",");
        if (locationStrings.length == 2) {
            result.setLatitude(Double.parseDouble(locationStrings[0]));
            result.setLongitude((Double.parseDouble(locationStrings[1])));
            return result;
        } else { return null; }
    } else  return null;
}
