Display inner Items under Certain List Item?

There is a ListView within which I have used a Dynamic Linear Layout to add inner elements. I want to display all the Specific Term wise inner data within a specific list (i.e. Only Specific Term Name to be displayed and all the information within the TermName). However, I am getting the inner item as Another List Item, i.e is not what I am expecting.

I want Specific Term under which the all Courses to be Displayed.
Can't I Display all the Courses under the same Specific Term Name?

Change your for loop to add similar items to same object
,
change it to
for (int i = 0; i < jArray.length(); i++) {
JSONObject jsonObject = jArray.getJSONObject(i);
System.out.println(i);
String course = jsonObject.getString("CourseName");
String examDescription = jsonObject.getString("examDescription");
if(arrayList.contains(examDescription))) {
student_list_courses.get(arrayList
.indexOf(examDescription)).addCourses(course);
}
else{
StudentProgressReportPojo progressReportPojo = new StudentProgressReportPojo(examDescription);
progressReportPojo.addCourses(course);
arrayList.add(examDescription);
student_list_courses.add(progressReportPojo);
}
}
also you need to change
viewHolder.student_progress_report_courses
.setText(student_list_courses.get(postion).getCourses().get(i));
in your getView() function to display all Courses not just getCourses().get(i))
you need to add textviews for each item getCourses returns.
something like this
for(int x=0;x<student_list_courses.get(postion).getCourses().size();x++){
LinearLayout coursesViewDynamic = (LinearLayout) inflater
.inflate(R.layout.student_progress_report_courses_listitem, parent, false);
TextView textView=(TextView) coursesViewDynamic.findViewById(R.id.student_progressreport_subject_coursename);
textView.setText(student_list_courses.get(postion)
.getCourses().get(i));
viewHolder.coursesLayout.addView(coursesViewDynamic);
}
Hope this helps.

You can use GSON/ Jackson to parse your JSON objects. You will find plenty of annotations to exclude EMPTY, NULL etc. etc. in these libraries. Also they provide a much easier code to read
An example for using GSON is given here

you can try this way,(change in listener)
String itemId ="";
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
String selValue = parent.getItemAtPosition(position).toString();
for(int z= 0; z<subcatNameList.size();z++){
if(selValue.trim().equal(""+subcatNameList.get(z).trim()){
// do some changes according to
itemId = subcattagidList.get(z);
new callAsukforChanges().execute();
}
}
}
I hope this will help you. thanks

add RecyclerView in layout
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view"
android:scrollbars="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
add dependencies
compile 'com.android.support:recyclerview-v7:23.1.1'
create a layout for each row of RecyclerView and name it list_row.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:focusable="true"
android:paddingLeft="16dp"
android:paddingRight="16dp"
android:paddingTop="10dp"
android:paddingBottom="10dp"
android:clickable="true"
android:background="?android:attr/selectableItemBackground"
android:orientation="vertical">
<TextView
android:id="#+id/title"
android:textColor="#color/title"
android:textSize="16dp"
android:textStyle="bold"
android:layout_alignParentTop="true"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</RelativeLayout>
create a JAVA file Model.java
public class Model {
public String title;
}
now create java file named as Adapter.java
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import java.util.List;
public class Adapter extends RecyclerView.Adapter<MoviesAdapter.MyViewHolder> {
private ArrayList<Model> modelArrayList=new ArrayList<>();
public class MyViewHolder extends RecyclerView.ViewHolder {
public TextView title;
public MyViewHolder(View view) {
super(view);
title = (TextView) view.findViewById(R.id.title);
}
}
public Adapter(ArrayList<Model> modelArrayList) {
this.modelArrayList = modelArrayList;
}
#Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.list_row, parent, false);
return new MyViewHolder(itemView);
}
#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
Movie movie = moviesList.get(position);
holder.title.setText(modelArrayList.get(position).title);
}
#Override
public int getItemCount() {
return modelArrayList.size();
}
}
in MainActivity.java
create a Arrylist of type Model
ArrayList<Model> modelArrayList=new ArrayList<>();
RecyclerView recyclerView;
recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext());
recyclerView.setLayoutManager(mLayoutManager);
prase data
JSONObject jsonObject = new JSONObject(ou_response);
JSONArray message = jsonObject.getJSONArray("categories");
for (int i = 0; i < message.length(); i++) {
Model model = new Model();
JSONObject temp = message.getJSONObject(i);
model.tittle = temp.getString("tittle");
modelArrayList.add(model);
}
create Adapter and set it to recyclerView
Adapter madapter = new Adapter(modelArrayList);
recyclerView.setAdapter(mAdapter);

creating RecyclerView in your xml file:
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view"
android:scrollbars="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
Declare the RecyclerView and JsonArray in your Activity class :
VolleyClass volleyClass;
JSONArray jsonArray = new JSONArray();
RecyclerAdapter recyclerAdapter;
RecyclerView recyclerView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_head_two_head);
volleyClass = VolleyClass.getInstance(this);
//volleyClass=new VolleyClass(this);
recyclerAdapter = new RecyclerAdapter();
recyclerView = (RecyclerView) findViewById(R.id.recyclerView);
recyclerView.setHasFixedSize(true);
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(HeadToHeadRandom.this, LinearLayoutManager.VERTICAL, false);
recyclerView.setLayoutManager(linearLayoutManager);
recyclerView.setAdapter(recyclerAdapter);
Retrieve Json data :
JsonObjectRequest jsObjRequest = new JsonObjectRequest(Request.Method.POST, URL.HEADTOHEAD_LIST.getURL(), urlObject, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.e("onResponse", response.toString());
try {
jsonArray = response.getJSONArray("Categories");
if (jsonArray != null) {
recyclerAdapter.notifyDataSetChanged();
}
} catch (JSONException e) {
e.printStackTrace();
}
mDialog.dismiss();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
// TODO Auto-generated method stub
mDialog.dismiss();
}
}) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json; charset=utf-8");
headers.put("User-agent", System.getProperty("http.agent"));
return headers;
}
#Override
public Priority getPriority() {
return Priority.IMMEDIATE;
}
};
volleyClass.addToRequestQueue(jsObjRequest);
Adapter Class like this:
class RecyclerAdapter extends RecyclerView.Adapter<RecyclerAdapter.HaderView> {
#Override
public HaderView onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_head_to_head, parent, false);
lastItem = recyclerView.getChildAdapterPosition(view);
return new HaderView(view);
}
#Override
public void onBindViewHolder(HaderView holder, int position) {
try {
holder.tv_category.setText(jsonArray.getJSONObject(position).getString("title"));
String image_path = jsonArray.getJSONObject(position).getString("icon");
if (image_path != null) {
imageLoader.displayImage(image_path, holder.img_head_to_head, options);
}
} catch (JSONException e) {
e.printStackTrace();

ImageView img_head_to_head;
HaderView(View v) {
super(v);
tv_category = (TextView) v.findViewById(R.id.tv_category);
img_head_to_head = (ImageView) v.findViewById(R.id.img_head_to_head);

Can't use Volley to display two custom ListView

I am a beginner in android, and i am trying to use Volley to create a custom list which contains list of images and text description for each. There are two activities as list view, downloaded json data using volley, use OnItemClickListener to start other activity. the first activity is complete to run, when i click the other one, the Logcat got nothing to show, but the second Listview activity is blank only have title...
This is Logcat i don't it has usefully or not.
All my Logcat
05-22 16:09:32.549: V/Monotype(14980): SetAppTypeFace- try to flip, app = com.wangjian.klmeet_sightseeing

I'm a newbie at this stuff so any help will be appreciated. Thanks in Advance.!

Firstly, private String URL_FEED = "http://wangjian.site90.net/json/api_klmeet_sightseeing_face.json"; in your MainActivity doesn't exist and when I tried it in AdvanceRestClient I got this:
So I tried looking more into directory structure of your WS and found there isn't any such URL you have mentioned as above.
Further more, I got security issues while trying to access your directory:
I am not sure what you are looking for seriously, but you could try with a valid URL in MainActivity and it should work fine.
Security issue creep me out literaly. :(
