Serialization problem with Enums at Android

Question

I\'m using XStream to serialize some objects to XML, and am facing a problem with Enums. The exception I get when I try to serialize the object: \"ObjectAccessException: inv

Answer 1

The only way i could find to get around this is to create a AbstractSingleValueConverter for enums and then register it with xstream.

public class SingleValueEnumConverter extends AbstractSingleValueConverter
{
    private final Class enumType;

    public SingleValueEnumConverter(Class type)
    {
        this.enumType = type;
    }

    public boolean canConvert(Class c)
    {
        return c.equals(enumType);
    }

    public Object fromString(String value)
    {
        return Enum.valueOf(enumType, value);
    }
}

Use

XStream xml = new XStream();
xml.registerConverter(new SingleValueEnumConverter([ENUM].class));
