Question

public Map<String, Object> toMap(JSONObject fees_history) throws JSONException {
    Map<String, Object> map = new HashMap<String, Object>();
    jsonArray = new JSONArray();
    int j = 0;
    Iterator<String> keysItr = fees_history.keys();
    while (keysItr.hasNext()) {
        String key = keysItr.next().toString();
        Object value = fees_history.get(key);
        if (value instanceof JSONArray) {
            value = toList((JSONArray) value);
        } else if (value instanceof JSONObject) {
            value = toMap((JSONObject) value);
            //How can i get the String value from this Object here
            //here i am logging
            Log.e("Value",value.toString());
            Unpaid_fees_detail_adapter unpaid_fees_detail_adapter = new Unpaid_fees_detail_adapter(ReportActivity.this, unpaid_fees_details);
            listView.setAdapter(unpaid_fees_detail_adapter);
        }
        map.put(key, value);
    }
    return map;
}

这是我的对象的价值

{date=29-07-2017,Reciept=RC1, Amount=11800}

我在那里评论过，我的问题是如何在Object中获取键值对。

我试过了很多方式使用map.get(Object)，但我没有做到。我只是想知道如何获得date,Receipt,Amount

的单独值

Answer 1

试试这个。

String response = "{date=29-07-2017,Reciept=RC1, Amount=11800}";
String responseConvert = response.replace("=", ":");
Map<String, String> map = new HashMap<>();
Iterator<String> sIterator = null;
try {
    sIterator = new JSONObject(responseConvert).keys();
    while (sIterator.hasNext()) {
        // get key
        String key = sIterator.next();
        // get value
        String value = new JSONObject(responseConvert).getString(key);
        map.put(key, value);
        Log.e("TAG", "key: " + key + ",value：" + value);
    }
} catch (JSONException e) {
    e.printStackTrace();
}

注意

JSON数据是非法的，因此我们必须将其转换。

String responseConvert = response.replace("=", ":");

使用Map<String,String>和Iterator<String>

Map<String, String> map = new HashMap<>(); Iterator<String> sIterator = new JSONObject(responseConvert).keys();

获取密钥和值

// get key String key = sIterator.next(); // get value String value = new JSONObject(responseConvert).getString(key);
