How to implement RecyclerView on a FrameLayout? - android-recyclerview

Question

I am learning RecyclerView and stuck in activity. I have a bottomNavigationView and a frame layout above the bottomNavigationView I want to show a RecyclerView on that FrameLayout. How can I do that?
There is no error in my program and i don't know why its not showing the RecyclerView.
This is the xml
<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="match_parent"
tools:context=".Bottom_nav">
<FrameLayout
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#id/bottomnavid"
/>
<android.support.design.widget.BottomNavigationView
android:id="#+id/bottomnavid"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
app:menu="#menu/bottom_nav"
/>
</RelativeLayout>
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:background="#FFEB3B"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="#+id/live_matchrecyclerid"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
<android.support.v7.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_margin="10dp"
android:padding="5dp"
app:cardCornerRadius="3dp"
app:cardElevation="5dp"
>
<TextView
android:id="#+id/cityid"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Hello"
android:textSize="50sp"
android:padding="5dp"/>
</android.support.v7.widget.CardView>
This is the myadapter class
public class Myadapter extends RecyclerView.Adapter<Myviewholder> {
ArrayList<String> Citynames;
Context c;
public Myadapter(ArrayList<String> citynames, Context c) {
Citynames = citynames;
this.c = c;
}
#NonNull
#Override
public Myviewholder onCreateViewHolder(#NonNull ViewGroup viewGroup, int i) {
View v = LayoutInflater.from(c).inflate(R.layout.cardview,viewGroup,false);
Myviewholder VH = new Myviewholder(v);
return VH;
}
#Override
public void onBindViewHolder(#NonNull Myviewholder myviewholder, int i) {
myviewholder.nametext.setText(Citynames.get(i));
}
#Override
public int getItemCount() {
return Citynames.size();
}
}
this is my viewholder class
public class Myviewholder extends RecyclerView.ViewHolder {
TextView nametext;
public Myviewholder(#NonNull View itemView) {
super(itemView);
nametext = itemView.findViewById(R.id.cityid);
}
}
This is my main class
public class Feature extends Fragment {
ArrayList<String> Citynames = new ArrayList<> (Arrays.asList("dhaka","rongpur","bagura",
"sylhet","vhola","lalmonirhut","khulna","cumillah","rajshahi"));
public Feature()
{
}
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container,
#Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.feature,container,false);
RecyclerView recyclerView = view.findViewById(R.id.featurerecyclerid);
LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity());
recyclerView.setLayoutManager(layoutManager);
Myadapter myadapter = new Myadapter(Citynames,getActivity());
recyclerView.setAdapter(myadapter);
return inflater.inflate(R.layout.feature,container,false);
}
}
No error is showing in my project but not showing the RecyclerView.

Answer 1

ok you just set your your recycler view before the fragment view created,I mostly metion you in your previuous question
set your recyler view in 'onViewCreated' method,see my answer there.And not to post same question again and again,you also can edit your question
