在Android中解析动态JSON [英] Parsing dynamic JSON in Android

问题描述

我有一个json对象是这样的:

I have a json Object is like this:

{
    Yg7R_: {
    fld_invoice: "Yg7R_"
    fld_order_id: "5"
        fld_orders: {
            4: {
                fld_oiid: "4"
                fld_date: "2014-03-27 00:00:00"
                fld_name: "20140327_H5epz2y4OB_IMG_20140326_020341.jpg"
                fld_loc: "../orders/oid_5/"
            }
        }
    }
    LldP_: {
    fld_invoice: "LldP_"
    fld_order_id: "7"
        fld_orders: {
            6: {
                fld_oiid: "6"
                fld_date: "2014-03-27 00:00:00"
                fld_name: "20140327_SovH7Xf3n2_IMG_20140326_020418.jpg"
                fld_loc: "../orders/oids_7/"
            }
        }
    }
    NYEO: {
        fld_invoice: "NYEO"
        fld_order_id: "24"
        fld_orders: {
            27: {
                fld_oiid: "27"
                fld_date: "2014-03-27 00:00:00"
                fld_name: "20140327_duLLsssVWA_IMG_20140326_020341.jpg"
                fld_loc: "orders/oid_24/"
            }
            28: {
                fld_oiid: "28"
                fld_date: "2014-03-27 00:00:00"
                fld_name: "20140327_F8ayA4vWrP_IMG_20140326_020405.jpg"
                fld_loc: "orders/oid_24/"
            }
            29: {
                fld_oiid: "29"
                fld_date: "2014-03-27 00:00:00"
                fld_name: "20140327_1FlYnuNbtr_IMG_20140326_020418.jpg"
                fld_loc: "orders/oid_24/"
            }
        }
    }
}

我试图这样解析:

    // result is the above json object.
    for(int i = 0; i < result.length(); i++){
    try {
        invoice = result.getJSONArray(<Some name here>); // this name is dynamic
        Log.d("invoice "+i, invoice);
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

但是我不知道如何访问动态名称.我们如何解析这样的JSON

but I don't get that how could i access the dynamic name. How could we parse such JSON

-注意-是的，所有值都带有引号，例如:"Yg& R _"

--Note-- Ya all the values has their quotes eg: "Yg&R_"

推荐答案

尝试使用此动态json解析器

Try this dynamic json parser

private void parseJson(JSONObject data) {

        if (data != null) {
            Iterator<String> it = data.keys();
            while (it.hasNext()) {
                String key = it.next();
                try {
                    if (data.get(key) instanceof JSONArray) {
                        JSONArray arry = data.getJSONArray(key);
                        int size = arry.length();
                        for (int i = 0; i < size; i++) {
                            parseJson(arry.getJSONObject(i));
                        }
                    } else if (data.get(key) instanceof JSONObject) {
                        parseJson(data.getJSONObject(key));
                    } else {
                        System.out.println(key + ":" + data.getString(key));
                    }
                } catch (Throwable e) {
                    try {
                        System.out.println(key + ":" + data.getString(key));
                    } catch (Exception ee) {
                    }
                    e.printStackTrace();

                }
            }
        }
    }
