I am trying to attach data in view.But I here show error on OnBind method.
Here is the code of mainActivity:
package com.example.recyclerview;
import androidx.appcompat.app.AppCompatActivity;
import androidx.recyclerview.widget.LinearLayoutManager;
import androidx.recyclerview.widget.RecyclerView;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
int [] image = {
R.drawable.deep_blue,R.drawable.dual_matter,R.drawable.gradiant,
R.drawable.light_blue,R.drawable.yellow,R.drawable.red
};
MyAdapter myAdapter;
String [] title,desc;
RecyclerView recyclerView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
recyclerView=findViewById(R.id.RecyclerViewID);
title=getResources().getStringArray(R.array.logo_name);
desc=getResources().getStringArray(R.array.logo_desc);
myAdapter =new MyAdapter(this,title,desc,image);
recyclerView.setAdapter(myAdapter);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
}
}
Here is the code of Adapter class:
package com.example.recyclerview;

myAdapterHolder.myimageView.setImageResource(image[i]);
}
#Override

return title.length;
}
public class MyAdapterHolder extends RecyclerView.ViewHolder {
TextView titleTV,descTV;
ImageView myimageView;
public MyAdapterHolder(#NonNull View itemView) {
super(itemView);
titleTV=itemView.findViewById(R.id.titleTextViewID);
descTV=itemView.findViewById(R.id.descTextViewID);
myimageView=itemView.findViewById(R.id.myImageViewID);
}
}
}
#Override
public void onBindViewHolder(#NonNull MyAdapterHolder myAdapterHolder, int position) {
myAdapterHolder.titleTV.setText(title[i]);
myAdapterHolder.descTV.setText(desc[i]);
myAdapterHolder.myimageView.setImageResource(image[i]);
}
As far as I can tell you are trying to use position for your index, but you are instead using the variable i. Try changing the i 's in this function to position. If you could post your stack trace that would help a bunch too.

I am new, and I am making an app that displays data in a cardView within a recyclerView in android studio. I am trying to be able to delete the data that is displayed on the cardView. The cardView and data gets deleted as it should, but once I go back to the activity holding the cardView and recyclerView, it's all still there. Does anyone know why this is happening? I'll post my code below

I have searched stackOverflow and reddit, but nothing seems to work. I have tried making the array array list instead.
I have the following code and result:
public class MyClass {
public static void main(String args[]) {
String[][] parent_table = {{"I-101", "First(parent)"}, {"I-102", "Second(parent)"}, {"I-103", "Third(parent)"}};
String[][] child_table = {{"I-101", "First-1(child)"}, {"I-101", "First-2(child)"}, {"I-102", "Second-1(child)"}, {"I-102", "Second-2(child)"}, {"I-103", "Third-1(child)"}};
for(String[] parent: parent_table) {
System.out.println(parent[1]);
for (String[] child: child_table) {
if (parent[0].equals(child[0])) {
System.out.println(child[1]);
}
}
}
}
}
First(parent)
First-1(child)
First-2(child)
Second-2(child)
Second-1(child)
Second-2(child)
Third(parent)
Third-1(child)

You have to initialize your recycler view by findViewById method befor setting adapter in onCreate.
Like,
recyclerView = findViewById(R.id.recView) //id of Recycler View which you given in your xml
I was trying to practice using the Recycler in Android Studio using Java.
I have made so much progress so far.
When I run the application it crashes immediately, I have checked the logs and I had an error on the below:
Attempt to invoke virtual method 'android.view.View androidx.recyclerview.widget.RecyclerView.findViewById(int)' on a null object reference
and
Attempt to invoke virtual method 'android.view.View androidx.recyclerview.widget.RecyclerView.findViewById(int)' on a null object reference
Below is my MainActivity class:
package com.example.recyleview;

import androidx.recyclerview.widget.RecyclerView;
import android.os.Bundle;
import android.widget.LinearLayout;
import java.util.ArrayList;
public class MainActivity extends AppCompatActivity {
private RecyclerView recView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
recView.findViewById(R.id.recView);
recView.setLayoutManager(new LinearLayoutManager(this));
setContentView(R.layout.activity_main);
ArrayList<Contact> contacts = new ArrayList<>();
contacts.add(new Contact("Jacob", "jacob#gmail.com", "later"));
contacts.add((new Contact("Sara ", "sara#gmail.com", "later")));
contacts.add(new Contact("Nino", "nino#gmail.com", "later"));
ContactsRecViewAdapter adapter = new ContactsRecViewAdapter(this);
adapter.setContacts(contacts);
recView.setAdapter(adapter);
}
}
and here is another class called ContactsRecViewAdapter

}
});
}
#Override
public int getItemCount() {
return contacts.size();
}
public void setContacts(ArrayList<Contact> contacts) {
this.contacts = contacts;
notifyDataSetChanged();
}
public static class ViewHolder extends RecyclerView.ViewHolder{
private final TextView txtName;
private final RelativeLayout parent;
public ViewHolder(#NonNull View itemView) {
super(itemView);
txtName = itemView.findViewById(R.id.txtName);
parent = itemView.findViewById(R.id.parent);
}
}
}
Change
recView.findViewById(R.id.recView);
to
recView = findViewById(R.id.recView);
Also you have duplicated:
setContentView(R.layout.activity_main);
You have to set the contentView before you try to find the views.
I want the app to open a page when the user taps on an item and pass some extra information to that intent. That's it. I tried about 7 - 10 onclickListener types but I didn't solve anything. I am posting my adapter class with the latest implementation ( that doesn't work ). Json works and the Recyclerview loads data and images from url with no problems.
