我已将jsonObject转换为Jsonarray
public class getData extends AsyncTask<String, String, String> {
@Override
protected String doInBackground(String... params) {
return JsonParser.makeHttpUrlConnectionRequest(url, getParam());
}
private List<NameValuePair> getParam() {
SharedPreferences preferences = ReportActivity.this.getSharedPreferences(getString(R.string.detail), MODE_PRIVATE);
enroll_no = preferences.getString(getString(R.string.loginenroll), "");
List<NameValuePair> list = new ArrayList<>();
list.add(new BasicNameValuePair("enroll_no", enroll_no));
// Log.e("List", String.valueOf(list.add(new BasicNameValuePair("enroll_no",enroll))));
Log.e("Request in Profile", String.valueOf(list));
return list;
}
@Override
protected void onPostExecute(String httpresponse) {
super.onPostExecute(httpresponse);
if (httpresponse == null) {
Toast.makeText(ReportActivity.this, "Unable to Connect", Toast.LENGTH_SHORT).show();
} else if (httpresponse.equals("error")) {
Toast.makeText(ReportActivity.this, "Internal Server Error", Toast.LENGTH_SHORT).show();
} else {
try {
responseParameter = new JSONObject(httpresponse);
JSONObject fees_history = responseParameter.getJSONObject("fees_history");
// JSONObject RC1 = fees_history.getJSONObject("RC1");
Iterator rc1 = fees_history.keys();
JSONArray jsonArray = new JSONArray();
int i = 0;
while (rc1.hasNext()) {
String key = (String) rc1.next();
jsonArray.put(fees_history.get(key));
JSONObject object = jsonArray.getJSONObject(i++);
JSONObject heading = object.getJSONObject("heading");
JSONArray details = object.getJSONArray("details");
Log.e("details", details.toString());
String Amount = heading.getString("Amount");
String date = heading.getString("date");
String Reciept = heading.getString("Reciept");
// for (int j = 0; j < details.length(); j++) {

Log.e("Amount", Amountt);
Log.e("Month", Month);
Unpaid_fees_detail unpaid_fees_detail = new Unpaid_fees_detail(Reciept, date, Amount,Amountt,Month);
unpaid_fees_details.add(unpaid_fees_detail);
}
} catch (JSONException e) {

}
Unpaid_fees_detail_adapter unpaid_fees_detail_adapter = new Unpaid_fees_detail_adapter(ReportActivity.this, unpaid_fees_details);

这是我的JsonArray

答案 0 :(得分：1)
你只是要fori循环
ArrayList<DetailItem> detailItems = new ArrayList<>();
JSONArray details = response.getJSONArray("details");
if (details != null) {
for (int k = 0; k < details.length(); k++) {
JSONObject jsonObject = details.getJSONObject(k);
String uniqueId = jsonObject.getString("unique_id");
String reciept = jsonObject.getString("Reciept");
// Your Code ...
DetailItem detailItem = new DetailIte();
detailItem.setUniqueId(uniqueId);
detailItem.setReciept(reciept);
// Your Code ...
detailItems.add(detailItem);
// Your Code ...
}
}
你创造了： JSONArray details = object.getJSONArray（“details”）;
所以我不了解： JSONObject detail = details.getJSONObject（i）;
从此行更改您的代码： JSONArray details = object.getJSONArray（“details”）;
喜欢：
JSONArray details = response.getJSONArray("details");
// List Of Custom Object Class 'DetailItem'
// It Contains fields of details object , unique_id and Reciept and etc
ArrayList<DetailItem> detailItems = new ArrayList<>();
if (details != null) {
for (int k = 0; k < details.length(); k++) {
JSONObject jsonObject = details.getJSONObject(k);
String uniqueId = jsonObject.getString("unique_id");
String reciept = jsonObject.getString("Reciept");
// Your Code ...
DetailItem detailItem = new DetailIte();
detailItem.setUniqueId(uniqueId);
detailItem.setReciept(reciept);
// Your Code ...
detailItems.add(detailItem);
// Your Code ...
}
}
