java - 我已将 jsonObject 转换为 JsonArray 我如何循环它

标签 java android json

  1. 我正在尝试转换我已经成功获得的 jsonArray 数据，但如何循环我的 jsonArray 以便我可以获得完整的详细信息 在 ListView 中。如果有多个数据，我如何附加我的数据 在同一个对象中并将其解析到 ListView 中。

  2. 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++) {

                        JSONObject detail = details.getJSONObject(i);

                        String Month = detail.getString("Month");

                        String Amountt = detail.getString("Amount");
                        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) {
                e.printStackTrace();
            }

            //  Log.e("RC1",RC1.toString());

             //   Log.e("fees_history", fees_history.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);
        }

    }

    这是我的 JsonArray

最佳答案

你只是为了让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 ...

    }
}

您创建了: JSONArray 详细信息 = object.getJSONArray("详细信息");

所以我不明白: JSONObject详细信息=详细信息.getJSONObject(i);

从这一行更改您的代码: JSONArray 详细信息 = object.getJSONArray("详细信息");

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 ...

    }
}
