JSON数据解析android

Question

This is JSON response I am getting.

I want to select first 45 records response then I want to select next 45 and so on.

How can I parse this data?

Help.

{
  "data": [
    {
      "id": "xxxxx"
    },
    {
      "id": "xxxxx"
    }
  ]
}

Something like this I am trying.

try {

    JSONObject rob = response.getJSONObject();

    JSONArray array = rob.getJSONArray("data");

    for(int i=0;i<array.length();i++){

        JSONObject friend = array.getJSONObject(i);

        Log.d("uid",friend.getString("id"));
    }

} catch (JSONException e) {e.printStackTrace();}

Answer 1

I wrote it without any IDE, it just is an idea and not more. You will need to check and write it correctly.

// Fields
final static int ITEMS_PER_REQUEST = 45;
int currentIndex = 0;
// Method body
try {
    JSONObject rob = response.getJSONObject();

    JSONArray array = rob.getJSONArray("data");
    int size = Math.min(array.Length, currentIndex + ITEMS_PER_REQUEST);

    while(currentIndex < size;) {
        JSONObject friend = array.getJSONObject(currentIndex);
        Log.d("uid",friend.getString("id"));
        ++currentIndex;
    }

} catch (JSONException e) {
    e.printStackTrace();
}
