如何将多维数组从android传递给soap web服务参数

Question

我有多维数组的问题，我在soap中有web服务，需要将此数组作为参数传递，如下所示：

HashMap<String, String> phone = new HashMap<String, String>();

    phone.put("internalId", "phone");
    phone.put("fieldId", "8");
    phone.put("displayName", "Phone");
    phone.put("value", "XXXXXXXXXXXX");
    custom_field.add(phone);
    /*Log.d("hash Phone", String.valueOf(phone));
    Log.d("hash Phone custom Field ", String.valueOf(custom_field));*/

HashMap<String, String> address = new HashMap<String, String>();

    address.put("internalId", "address");
    address.put("fieldId", "3");
    address.put("displayName", "Address");
    address.put("value", " XXXX XXXXX, XXXX");
    custom_field.add(address);
    /*Log.d("hash Address", String.valueOf(phone));
    Log.d("hash Address custom Field ", String.valueOf(custom_field));*/
HashMap<String, String> nationalid = new HashMap<String, String>();

    nationalid.put("internalId", "nationalid");
    nationalid.put("fieldId", "13");
    nationalid.put("displayName", "National-ID");
    nationalid.put("value", "XXXXXXX");
        custom_field.add(nationalid);

HashMap<String, String> maritalstatus = new HashMap<String, String>();

    maritalstatus.put("internalId", "maritalstatus");
    maritalstatus.put("fieldId", "16");
    maritalstatus.put("displayName", "Marital status");
    maritalstatus.put("value", "Single");

    custom_field.add(maritalstatus);

我想像下面的示例PHP数组一样传递数组：

Array
(
    [0] => Array
        (
            [internalId] => phone
            [fieldId] => 8
            [displayName] => Phone
            [value] => XXXXXXXXX
        )

    [1] => Array
        (
            [internalId] => address
            [fieldId] => 3
            [displayName] => Address
            [value] =>  XXXX XXXXX, XXXX
        )

    [2] => Array
        (
            [internalId] => nationalid
            [fieldId] => 13
            [displayName] => National-ID
            [value] => XXXXXXX
        )

    [3] => Array
        (
            [internalId] => maritalstatus
            [fieldId] => 16
            [displayName] => Marital status
            [value] => Single
        )

)

并将soapfault错误视为错误，如

java.lang.RuntimeException: Cannot serialize:

任何帮助如何通过android完成此任务。

我已尝试过hashmap嵌套以及arraylist嵌套，但它们都没有为我工作。
