java - 如何在retrofit中调用动态嵌套json对象

Question

如何使用 Retrofit 在 android 中调用动态嵌套 json 对象。我有以下格式的 JSON 结果，我的问题是:如何访问“类别”的内容，因为“食品”、“时尚”等是所有动态值？给我一个想法。

{
"offer": {
    "id": "JUN_HAIR_1302177631",
    "categories": {
        "electronics": {
            "address_1": "12 Mott St",
            "address_2": null,
            "city": "New York",
            "cross_streets": "Chatham Sq & Worth St",
            "state": "NY",
            "zip": "10013"
        },
        "food": {
            "address_1": "12 Mott St",
            "address_2": null,
            "city": "New York",
            "cross_streets": "Chatham Sq & Worth St",
            "state": "NY",
            "zip": "10013"
        },
        "fashion": {
            "address_1": "12 Mott St",
            "address_2": null,
            "city": "New York",
            "cross_streets": "Chatham Sq & Worth St",
            "state": "NY",
            "zip": "10013"
        },
        .........
        .........

    }
}
}

您可以使用HashMap:

class Offer {
    private String id;
    private HashMap<String, Category> categories;

    // getters and setters
}

Category 数据类应如下所示:

class Category {
    @SerializedName("address_1")
    private String firstAddress;
    @SerializedName("address_2")
    private String secondAddress;
    private String city;
    @SerializedName("cross_streets")
    private String crossStreets;
    private String state;
    private String zip;

    // getters and setters;
}
