使用 Gson 解析动态 JSON 数据并将其存储在 Android 的 SQlite DB 中

Question

我在我的 Android 应用程序中从服务器收到此 JSON 响应，我想通过 Gson 解析此数据，在我的 Json 响应权限标签中可能包含 20-25 个数据，其键为 1、2， ...权限的每个值都包含由#键分隔的两个信息我必须只显示那些作为响应而进入权限的东西。解析的对象类（Pojo 或模型类必须Parcelable 实现） 我的应用程序也支持离线功能，所以需要建议我在解析时如何将数据同时存储在数据库中。

[{
    "permission": {
        "0": "Title#RaqStar",
        "1": "Desc#Reader of Raw Star",
        "3": "Tytpe#Entertainment",
        "4": "Rating#4.5"
    },
    "id": "233",
    "name": "Movie Raw Star"
}, {
    "permission": {
        "0": "Title#RaqStar",
        "3": "Tytpe#Entertainment",
        "4": "Rating#4.5"
    },
    "id": "233",
    "name": "Movie Raw Star"
}, {
    "permission": {
        "1": "Desc#Reader of Raw Star",
        "3": "Tytpe#Entertainment",
        "4": "Rating#4.5"
    },
    "id": "233",
    "name": "Movie Raw Star"
}, {
    "permission": {
        "1": "Desc#Reader of Raw Star",
        "4": "Rating#4.5"
    },
    "id": "233",
    "name": "Movie Raw Star"
}]

    //  Whole response array I took as a String "data"
    try {
        JSONArray array = new JSONArray(data);
        for (int i = 0; i < array.length(); i++) {
             responseJSonObj = array.getJSONObject(i);
             System.out.println(
             generateTitleInfoMap(responseJSonObj.
             getJSONObject("permission")));
        }

    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }


public static HashMap<String, String> generateTitleInfoMap(JSONObject titleInfoMap) {
    try {
        HashMap<String, String> mapdataVal = new HashMap<String, String>();

        if (titleInfoMap.length() > 0) {
            Iterator keys = titleInfoMap.keys();
            while (keys.hasNext()) {
                // loop to get the dynamic key
                String currentDynamicKey = (String) keys.next();
                String[] ar = (titleInfoMap.getString(currentDynamicKey)).split("#");

                mapdataVal.put(ar[0], ar[1]);
            }
        }
        return mapdataVal;
    } catch (JSONException e) {

    }
    return null;
}
