答
这是正确的答案.
try {
JSONObject res = new JSONObject(response);
if (res.getString("status").equalsIgnoreCase("success")) {
JSONObject obj = res.getJSONObject("data");
JSONArray rootCauseIdentificationArray = obj.getJSONArray("root_cause_identification");
for(int i = 0; i<rootCauseIdentificationArray.length(); i++){
JSONObject objData = rootCauseIdentificationArray.getJSONObject(i);
//iterate the object here and add to the list
RootCauseIdentificationModel model = new RootCauseIdentificationModel( objData.getString("id"), objData.getString("root_cause_identified"), objData.getString("solution_implemented"), objData.getString("implementaion_date"));
dataList.add(model);
}
stepsList.add(new TQMSavedDataModel(obj.getString("tangible_benefits"),
obj.getString("intangible_benefits"),
obj.getString("total_annual_savings"),
dataList));
tangibleBenefits.setText(obj.getString("tangible_benefits"));
intangibleBenefits.setText( obj.getString("intangible_benefits"));
annualAmount.setText(obj.getString("total_annual_savings"));
}
} catch (JSONException e) {
e.printStackTrace();
dialog.dismiss();
