我是来自服务器的这个json响应。
{
"Patient Data 1": [
{

}
现在我想显示患者的列表视图，其中包含数据“Name”，“Postal_Code”，“Email Id”，“Entered_date”，“EDD_Date”和行项目中的按钮。因此，当点击此按钮时，我再次获得数据“Entered_Date”和“Weight_Date”的列表视图。
我已经解析了以下数据。
public void getPatientData（final String patientName）{
final ProgressDialog dialog = new ProgressDialog(this);
dialog.setTitle("Please wait..");
dialog.show();
final String BASE_URL = "http://spirantcommunication.com/andriod/grl/doctor_show.php?";
final String NAME_PARAM = "name";
Uri uri = Uri.parse(BASE_URL).buildUpon()
.appendQueryParameter(NAME_PARAM, patientName)
.build();
String url = uri.toString();
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(url, null,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
dialog.dismiss();
int count = response.length();
try {
if (count == 1 && response.getJSONArray("Patient Data 1").
getJSONObject(0).getString("Message").equals("No Record Found for this Patient")){
Toast.makeText(getApplicationContext(), "No Record for this patient", Toast.LENGTH_SHORT).show();
} else if (count >= 1 && response.getJSONArray("Patient Data 1").
getJSONObject(0).getString("Name").equalsIgnoreCase(patientName)){
List<PatientModel> list = new ArrayList<>();
ArrayList<WeightModel> weightModels = new ArrayList<>();
PatientModel patientModel = null;
for (int i = 1; i <= count; i++){
try {
JSONArray array = response.getJSONArray("Patient Data " + i);
JSONObject jsonObject1 = array.getJSONObject(0);
JSONObject jsonObject2 = array.getJSONObject(1);
String patientName = jsonObject1.getString("Name");
String patientPostalCode = jsonObject1.getString("Postal_Code");
String patientEmailId = jsonObject1.getString("Email_Id");
String patientEnteredEddDate = jsonObject2.getString("Entered_Date");
String patientEddDate = jsonObject2.getString("EDD_Date");
Log.v("Patient Name", patientName);
Log.v("Patient Postal Code", patientPostalCode);
Log.v("Patient Email Id", patientEmailId);
Log.v("Selected Edd Date", patientEnteredEddDate);
Log.v("Edd Date", patientEddDate);
patientModel = new PatientModel();
patientModel.setPatientName(patientName);
patientModel.setPatientPostalCode(patientPostalCode);
patientModel.setPatientEmail(patientEmailId);
patientModel.setPatientSelectedEddDate(patientEnteredEddDate);
patientModel.setPatientEddDate(patientEddDate);
for (int j = 2; j < array.length(); j++){
JSONObject object = array.getJSONObject(j);
WeightModel weightModel = new WeightModel();
weightModel.setSelectWeightDate(object.getString("Entered_Date"));
weightModel.setWeightValue(object.getString("Weight_log"));
weightModels.add(weightModel);
patientModel.setWeightModels(weightModels);
Log.v("Weight Entered Date", object.getString("Entered_Date"));
Log.v("Weight Value", object.getString("Weight_log"));
}
list.add(patientModel);
}catch (JSONException e){
e.printStackTrace();
}
}
PatientRecordCustomAdapter adapter = new PatientRecordCustomAdapter(list, getApplicationContext());
listView.setAdapter(adapter);
}
} catch (JSONException e){
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
}
});
jsonObjectRequest.setTag(TAG);
jsonObjectRequest.setRetryPolicy(new DefaultRetryPolicy(20 * 1000, 1, 1.0f));
ApplicationController.getInstance().addToRequestQueue(jsonObjectRequest, TAG);
}
我使用的模型类是
public class PatientModel {
private String patientName;
private String patientEmail;
private String patientPostalCode;
private String patientSelectedEddDate;
private String patientEddDate;
private ArrayList<WeightModel> weightModels = new ArrayList<>();
public String getPatientName() {
return patientName;
}
public void setPatientName(String patientName) {
this.patientName = patientName;
}
public String getPatientEmail() {
return patientEmail;
}
public void setPatientEmail(String patientEmail) {
this.patientEmail = patientEmail;
}
public String getPatientPostalCode() {
return patientPostalCode;
}
public void setPatientPostalCode(String patientPostalCode) {
this.patientPostalCode = patientPostalCode;
}
public String getPatientSelectedEddDate() {
return patientSelectedEddDate;
}
public void setPatientSelectedEddDate(String patientSelectedEddDate) {
this.patientSelectedEddDate = patientSelectedEddDate;
}
public String getPatientEddDate() {
return patientEddDate;
}
public void setPatientEddDate(String patientEddDate) {
this.patientEddDate = patientEddDate;
}
public ArrayList<WeightModel> getWeightModels() {
return weightModels;
}
public void setWeightModels(ArrayList<WeightModel> weightModels) {
this.weightModels = weightModels;
}
}
我使用的自定义适配器是
公共类PatientRecordCustomAdapter扩展了BaseAdapter {
private List<PatientModel> data;
private Context context;
public PatientRecordCustomAdapter(List<PatientModel> data, Context context) {
this.context = context;
this.data = data;
}
@Override
public int getCount() {
return data.size();
}
@Override
public Object getItem(int position) {
return data.get(position);
}
@Override
public long getItemId(int position) {
return 0;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
if (convertView == null){
convertView = LayoutInflater.from(context).inflate(R.layout.item_patient_record, parent, false);
}
TextView patientName = (TextView) convertView.findViewById(R.id.tvPatientName);
patientName.setText("Patient Name: " + data.get(position).getPatientName());
TextView patientPostalCode = (TextView) convertView.findViewById(R.id.tvPostalCode);
patientPostalCode.setText("Patient Postal Code: " + data.get(position).getPatientPostalCode());
TextView patientEmailId = (TextView) convertView.findViewById(R.id.tvEmailId);
patientEmailId.setText("Patient Email Id: " + data.get(position).getPatientEmail());
TextView selectedEddDate = (TextView) convertView.findViewById(R.id.tvSelectedEddDate);
selectedEddDate.setText("Patient Selected Edd Date: " + data.get(position).getPatientSelectedEddDate());
TextView eddDate = (TextView) convertView.findViewById(R.id.tvEdd);
eddDate.setText("Patient Edd Date: " + data.get(position).getPatientEddDate());
ArrayList<WeightModel> list = data.get(position).getWeightModels();
int size = list.size();
Log.v("Size", String.valueOf(size));
for (WeightModel model1 : list){
Log.v("Selected Weight Date", model1.getSelectWeightDate());
Log.v("Select Weight Value", model1.getWeightValue());
}
Button button = (Button) convertView.findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(context, CheckWeightDataActivity.class);
// intent.putExtra("Weight List", (ArrayList<WeightModel>) weightData);
//intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
//context.startActivity(intent);
}
});
return convertView;
}
}
但是我将这个日志猫“Entered_Date”和“Weight_log”作为

我得到的是四个而不是两个。请帮帮我。
答案 0 :(得分：0)
首先根据您的要求更改您的json的结构。喜欢以下。
[
{
"Name": "priya",
"Postal_Code": "110056",
"Email_Id": "priya@yahoo.co.in",
"weightModels": [
{
"Entered_Date": "8Jul2015",
"EDD_Date": "15Apr2016"
},
{
"Entered_Date": "8Jun2015",
"Weight_log": "65"
},
{
"Entered_Date": "8Jun2015",
"Weight_log": "60"
},
{
"Entered_Date": "8Jul2015",
"Weight_log": "65"
}
]
},
{
"Name": "priya",
"Postal_Code": "110056",
"Email_Id": "priya@yahoo.co.in",
"weightModels": [
{
"Entered_Date": "8Jul2015",
"EDD_Date": "15Apr2016"
},
{
"Entered_Date": "8Jun2015",
"Weight_log": "65"
},
{
"Entered_Date": "8Jun2015",
"Weight_log": "60"
},
{
"Entered_Date": "8Jul2015",
"Weight_log": "65"
}
]
}
]
然后使用Gson
Gson gson = new Gson();
for(int i=0;i<jsonArray.lenght();i++){
PatientModel patient = gson.fromJson(jsonArray.get(i),PatientModel.class);
}
答案 1 :(得分：0)
如果你的预期结果加倍，那么你的循环可能就错了。
以loggin开头＆＃34; array.length（）＆＃34;和＆＃34;计数＆＃34;值以查看它们是否具有预期值，如果大小超出预期值，则表示您已找到问题。
否则一步一步地调试你的代码（添加断点），你会更清楚地看到它出错的地方，然后盯着几页代码更容易
