Hi Developers while Developing Android Project we commonly use RecyclerView for displaying Data in the form of list. If we have to create multiple times we going to copy past the code and modify the code to avoid this we have simple solution in-front of us. Follow these steps.

1. Open the Settings dialog in android studio from File->Settings then select Editor->File and Code Templates option then add new file template by clicking + icon

Creating File Templates

2. Then Provide the name for the template Eg. RecyclerViewAdapter

Template name RecyclerViewAdapter.

3. Then Past the provided code here

#if (${PACKAGE_NAME} != “”)package ${PACKAGE_NAME};#end

import android.content.Context;
import android.support.annotation.NonNull;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import java.util.ArrayList;

public class ${NAME} extends RecyclerView.Adapter<${NAME}.${ViewHolderName}> {
private Context context;
private ArrayList<String>list;

public ${NAME}(Context context,ArrayList<String> list) {
this.context = context;
this.list=list;
}
@NonNull
@Override
public ${NAME}.${ViewHolderName} onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
View view = LayoutInflater.from(context).inflate(R.layout.${Layout}, viewGroup, false);
return new ${NAME}.${ViewHolderName}(view);
}

@Override
public void onBindViewHolder(@NonNull ${NAME}.${ViewHolderName} viewHolder, int i) {

}

@Override
public int getItemCount() {
return list.size();
}
class ${ViewHolderName} extends RecyclerView.ViewHolder{
public ${ViewHolderName}(@NonNull View itemView) {
super(itemView);
}
}
