XML : RecyclerView display first item of the dynamic list only.

I have a dynamic list of several name. But, the RecyclerView displays the first item of the list only. What can be done to solve that problem?

For RecyclerView

routes_recyclerview.xml includes:

  <?xml version="1.0" encoding="utf-8"?>  <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"      xmlns:app="http://schemas.android.com/apk/res-auto"      xmlns:tools="http://schemas.android.com/tools"      android:layout_width="match_parent"      android:layout_height="wrap_content"      app:layout_behavior="@string/appbar_scrolling_view_behavior"      tools:context=".ui.activities.RoutesAssignActivity"      tools:showIn="@layout/activity_routes_assign"      android:layout_marginStart="10dp"      android:layout_marginEnd="10dp">      <android.support.v7.widget.RecyclerView      xmlns:android="http://schemas.android.com/apk/res/android"      android:id="@+id/recyclerView"      android:layout_width="match_parent"      android:layout_height="match_parent"      android:scrollbars="vertical"      android:layout_marginTop="10dp"  />  </RelativeLayout>    

For displaying the list name,

routes_recycler_listview.xml includes:

  <?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="wrap_content">      <TextView          android:id="@+id/textView"          android:layout_width="match_parent"          android:layout_height="match_parent"          android:layout_alignParentTop="true"          android:gravity="center_vertical"          android:paddingEnd="0dp"          android:paddingStart="10dp"          android:textColor="@color/md_black_1000"          android:textSize="20sp" />  </RelativeLayout>    

I includes header of the list. So, for header, I have

view_header.xml includes:

  <?xml version="1.0" encoding="utf-8"?>  <TextView      xmlns:android="http://schemas.android.com/apk/res/android"      xmlns:tools="http://schemas.android.com/tools"      android:layout_width="match_parent"      android:layout_height="wrap_content"      android:padding="16dp"      android:background="#001F3F"      android:textSize="28sp"      android:textStyle="bold"      android:textColor="@android:color/white"      tools:context=".ui.activities.RoutesAssignActivity"      />    

This getter and setter method for routes class:

Routes.jave includes:

  public class Routes{     @SerializedName("assignDate")      private String assignDate;      @SerializedName("routeName")      private String routeName;        public String  getAssignDate() {          return assignDate;      }      public void setAssignDate(String assignDate) {          this.assignDate = assignDate;      }        public String getRouteName() {          return routeName;      }        public void setRouteName(String routeName) {          this.routeName = routeName;      }  }    

To list the total routes, i have RoutesList.java. Here,

  public class RoutesList implements Comparable<RoutesList>{        @SerializedName("date")      private String date;      @SerializedName("routes")      private List<Routes> routes = new ArrayList<>();        public String getDateString() {          return date;      }        public Date getDate() {          SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd", Locale.US);          try {              return format.parse(getDateString());          } catch (ParseException e) {              // TODO Auto-generated catch block              e.printStackTrace();          }          return null;      }        public void setDate(String date) {          this.date = date;      }        public List<Routes> getRoutes() {          return routes;      }        public void setRoutes(List<Routes> routes) {          this.routes = routes;      }        @Override      public int compareTo(@NonNull RoutesList another) {          SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd", Locale.US);          try {              Date date = format.parse(another.getDateString());              return date.compareTo(getDate());          } catch (ParseException e) {              // TODO Auto-generated catch block              e.printStackTrace();          }          return 0;      }  }    

In my RecyclerViewRecyclerAdapter.java, i have: At ViewHolder i use:

  public TextView textView;            public ViewHolder(View v) {              super(v);              textView = (TextView) v.findViewById(R.id.textView);          }    

At onCreateViewHolder method, i use:

  public ViewHolder onCreateViewHolder(final ViewGroup parent, final int viewType) {          this.context = parent.getContext();          return new ViewHolder(LayoutInflater.from(context)                  .inflate(R.layout.routes_recycler_listview, parent, false));      }    

At onBindViewHolder method, i use:

  public void onBindViewHolder(final ViewHolder holder, final int position) {  holder.textView.setText(item.getRoutes().get(position).getRouteName());        }    

At RoutesAssignActivity.java class, i use :

  recyclerView.addItemDecoration(new HorizontalDividerItemDecoration.Builder(this).build());          adapter = new StickyHeaderListView(routes,this);          final StickyRecyclerHeadersDecoration headersDecor = new StickyRecyclerHeadersDecoration(adapter);          recyclerView.addItemDecoration(headersDecor);          RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getApplicationContext());          recyclerView.setLayoutManager(layoutManager);          recyclerView.setAdapter(adapter);    

After all, i only get this:

How do i get all name in list ?
