如何访问 JSONArray 中的每个键和值
我有一个如下的 JSONArray.如何按顺序访问其中的每个键和值.
I have a JSONArray as below. How can I access each key and value in it in order.
JSONArray = [{"a":1},{"b":2,"c":3},{"d":4},{"e":5,"f":7}]
推荐答案
你可以试试下面的代码:
You can try following code:
JSONArray jsonArray = new JSONArray("[{"a":1},{"b":2,"c":3},{"d":4},{"e":5,"f":7}]");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject json = jsonArray.getJSONObject(i);
Iterator<String> keys = json.keys();
while (keys.hasNext()) {
String key = keys.next();
System.out.println("Key :" + key + " Value :" + json.get(key));
}
}
