please help me out
I see the issue.
userAdapter=new UserAdapter(listData);
recyclerView.setAdapter(userAdapter);
Here you are initializing your UserAdapter. Notice that you are calling the wrong constructor or perhaps you have not implemented it.
// You should call this instead
public UserAdapter(Context context,List<Showuser>listData)
{
this.context=context;
this.listData=listData;
}
// You are calling this empty constructor
public UserAdapter(List<Showuser> listData) {
}
You should initialize your adapter like below.
userAdapter=new UserAdapter(ViewUser.this, listData);
You miss setting the list in adapter constructor, so change below
public UserAdapter(List<Showuser> listData) {
}
With
public UserAdapter(List<Showuser> listData) {
this.listData=listData;
}
Also, the list might be null, so change the return value of getItemCount()
#Override
public int getItemCount() {
return listData.size();
}
with
#Override
public int getItemCount() {
return listData == null? 0: listData.size();
}

You can create custom dialog.
Add RecyclerView in your XML file layout if don't have any layout create it.
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/fl_dialog"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:minHeight="300dp">
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/rv_dialog"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</FrameLayout>
Then initialize your RecyclerView and any other view in onCreateView
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
//TODO Change 'frag_mdialog' to your custom view XML layout
View v = inflater.inflate(R.layout.frag_mdialog, container, false);
view = v;
// Do all the stuff to initialize your custom view
RecyclerView recyclerView = view.findViewById(R.id.rv_dialog);
return v;
}
I hope this help you.
Problem at line below
dialog.show(((AppCompatActivity)c).getSupportFragmentManager()
c is Context so cannot be cast to AppCombatActivity
Try Sending Activity object in MyAdaptor class like below
public MyAdaptor (Activity ctx,ArrayList<Student> list)
and In MainActivity.java class you need to pass Activity object like this below -
MyAdaptor myAdaptor = new MyAdaptor(MainActivity.this,list);

In the ChatFragment.java, you should be returning the view you have created - penis, and not inflater.inflate(R.layout.fragment_chats, container, false). In this case, an empty view is returned and not the one you are creating.
I've got some problem with my RecyclerView. I want to add a bubble widget that creates a new circle with message (just like in messanger). Problem is that bubble must be placed in separate XML layout file so I cannot add it to the "item" layout that I have in my adapter. Inside bubble layout I have simply TextView, however I don't want to display normal text - it would be too easy ;) I want to display data I get from API. Another words - I need access to TextView that is inside Bubble layout in my adapter. Please, help! :)

You can pass your bubble TextView as aprameter to the adapter constructor.
private TextView mBubbleTextView;
public ConcertAdapter(Context context, List<Concert> concerts, TextView bubbleTextView) {
this.inflater = LayoutInflater.from(context);
this.concertList = concerts;
this.context = context;
this.mBubbleTextView = bubbleTextView;
}
Now you have the bubble TextView in your adapter, so can update it from any method.
This is the Java file of the fragment I wish to insert recycler view. Please dont worry about the package name which I deleted for some reasons.
import android.app.Activity;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import java.util.ArrayList;
import java.util.List;
public class Dashboard extends Fragment {
private RecyclerView recyclerView;
private RecyclerAdapter adapter;
/**
* Returns a new instance of this fragment for the given section number.
*/
public static Dashboard newInstance() {
Dashboard fragment = new Dashboard();
return fragment;
}
public Dashboard () {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.activity_dashboard, container,
false);
recyclerView = (RecyclerView) rootView.findViewById(R.id.drawerlist);
adapter=new RecyclerAdapter(getActivity().getData());
recyclerView.setAdapter(adapter);
recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
return rootView;
}
public static List<Information> getData(){
List<Information> data=new ArrayList<>();
String[] titles={"Rooms Occupied","RoomsVacant","Check-In","Check-Out","Extensions","Confirmations","Cancellations"};
for(int i=0;i<titles.length;i++)
{
Information current =new Information();
current.title=titles[i];
data.add(current);
}
return data;
}
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
}
}
This is my Adapter class
import android.content.Context;
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.Collections;
import java.util.List;
/**

public class RecyclerAdapter extends RecyclerView.Adapter<RecyclerAdapter.MyViewHolder> {
private LayoutInflater inflater;
List<Information> data= Collections.emptyList();
public RecyclerAdapter(Context context, List<Information> data){
inflater=LayoutInflater.from(context);
this.data=data;
}
#Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view=inflater.inflate(R.layout.custom_row, parent,false);
MyViewHolder holder=new MyViewHolder(view);
return holder;
}
#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
Information current=data.get(position);
holder.title.setText(current.title);
}
#Override
public int getItemCount() {
return 0;
}
class MyViewHolder extends RecyclerView.ViewHolder{
TextView title;
public MyViewHolder(View itemView) {
super(itemView);
title= (TextView) itemView.findViewById(R.id.viewText);
}
}
}
This is Layout file of the fragment in which I want to use the recycler view
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/viewImage"
android:background="#drawable/ic_dashboard"
android:layout_gravity="center_vertical"
android:gravity="center"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:id="#+id/viewText"
android:text="Dummy Text"
android:textStyle="bold"
android:layout_gravity="left"
android:gravity="center" />
</LinearLayout>
Since I'm new to stackoverflow I don't have enough reputations to add image. So I will attach the screenshot in the comments below. Please take a look at it to know what is happening here exactly. Thanks!
Why you call getActivity().getData(), just call getData().
And in your Adapter class:
#Override
public int getItemCount() {
return data.size();
}
It can't just return zero, you should return the data size.
