Parse Hashtable in JSON， perfect(jsonencode).但是我不知道如何在Hashtable(jsondecode)中解析json。(安卓)

Question

我创建了一个JSON编码，您在其中输入HashTable (public Hashtable<?, ?> JSonDecode(String data) {... return objJS.toString(); })并获得JSON格式的字符串。即:

如果我有一个Hashtable with this (Hashtable in Hashtable):

例子Hashtable :

Hashtable<String, Object> exampleHT = new Hashtable<String, Object>();
    exampleHT.put("Color", "Red");
    exampleHT.put("OtherKey", "OtherValue");
    exampleHT.put("OtherKey2", "OtherValue2");
Hashtable<String, Object> country = new Hashtable<String, Object>();
    country.put("Spain", "Madrid");
    country.put("France","Paris");
    country.put("Italy", "Rome");
Hashtable<String, String> pokemon = new Hashtable<String, String>();
    pokemon.put("Pikachu", "Electric");
    pokemon.put("Charmander","Fire");
country.put("Pokemons", pokemon);
exampleHT.put("Countries", country);

我使用我的函数(JSonEncode(exampleHT);)，我得到这个字符串:

{
    "Color":"Red",
    "Countries":{
        "Spain":"Madrid",
        "France":"Paris",
        "Italy":"Rome",
        "Pokemons":{
            "Pikachu":"Electric",
            "Charmander":"Fire"
        }
    },
    "OtherKey":"OtherValue",
    "OtherKey2":"OtherValue2"
}

它工作得很好!我的问题是创建反向过程，使用JSonDecode。

Hashtable<?, ?> hashUnknown = JSonDecode(jsonStringExample);
public Hashtable<?, ?> JSonDecode(String data) {
 // I do not know how to parse json in Hashtable, without indicating the tags manually.

}

我不知道如何在哈希表中解析json，而不手动指示标签。也就是说，没有它:

JSONArray menuObject = new JSONArray (jObject.getString ("Color"));
JSONArray menuObject = new JSONArray (jObject.getString ("Countries"));

这应该是动态的，不需要知道json内容，不需要手动编写颜色，国家，....

有什么想法或建议吗?谢谢你,

您可以在JSONObject (jObject)的键上获得一个迭代器对象(java.util.Iterator)你可以这样写:

Iterator<String> it = jObject.keys();
String key = null;
Object value = null;
while (it.hasNext()) {
    key = it.next();
    value = jObject.get(key);
    // Then test the instance of the value variable
    // and perform some logic
}
