Steps to use Edittext in list in your project.

1. Crate a project(EdittextInListDemo) in android studio.
   
   
2. Create a class MainActivity.Java and update it-
   
   
   
   
   

   package com.pankaj.gsolc.edittextinadaptersdemo;
   
   import android.support.v7.app.AppCompatActivity;
   import android.os.Bundle;
   import android.support.v7.widget.GridLayoutManager;
   import android.support.v7.widget.LinearLayoutManager;
   import android.support.v7.widget.RecyclerView;
   import android.text.Editable;
   import android.text.TextWatcher;
   import android.view.View;
   import android.widget.EditText;
   import android.widget.Toast;
   
   import java.util.ArrayList;
   import java.util.Calendar;
   import java.util.List;
   
   public class MainActivity extends AppCompatActivity {
       //create objects    private List<Data> data = new ArrayList<>();
       private MyAdapter myAdapter;
       RecyclerView recyclerView;
   
       @Override    protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_main);
           //initialize        recyclerView = findViewById(R.id.recyclerView);
   
           //add one data        Data data = new Data();
           data.setPosition(0);
           data.setString("");
           this.data.add(data);
   
           //initialize adapter        myAdapter = new MyAdapter(this, this.data);
   
           //add layout manager to recycler view        recyclerView.setLayoutManager(new GridLayoutManager(this, 2));
   
           //add adapter        recyclerView.setAdapter(myAdapter);
   
       }
   
       public void addOneMore(View view) {
   
           //Check if more than one data available, Than previous edittext should not be empty.        if (data.size() > 0)
               if (data.get(0).getString().isEmpty()){
                   Toast.makeText(this, "Please fill the empty fields first.", Toast.LENGTH_SHORT).show();
                   return;
               }
               
           //Create and add one blank data to entry        Data data = new Data();
           data.setPosition(this.data.size());
           data.setString("");
           this.data.add(0, data);
   
           //notify adapter        myAdapter.notifyDataSetChanged();
       }
   
       public void showData(View view) {
           //check if no data available, than return from here        if (data.size() < 1)
               return;
   
           String enteredData = "";
   
           for (Data data : data) {
               enteredData += data.getString() + "\n";
           }
   
           Toast.makeText(this, enteredData, Toast.LENGTH_SHORT).show();
       }
   }
   
   
   

    
3. Create a class Data.java to store data.
   
   
   
   

   package com.pankaj.gsolc.edittextinadaptersdemo;
   
   /** * Created by gsolc on 8/11/17. */
   public class Data {
       int position;
       String string;
   
       public int getPosition() {
           return position;
       }
   
       public void setPosition(int position) {
           this.position = position;
       }
   
       public String getString() {
           return string;
       }
   
       public void setString(String string) {
           this.string = string;
       }
   }
   

   
   
4. Create MyAdapter.java and update it-
   
   
   
   

   package com.pankaj.gsolc.edittextinadaptersdemo;
   
   import android.app.Activity;
   import android.support.v7.widget.RecyclerView;
   import android.text.Editable;
   import android.text.TextWatcher;
   import android.view.LayoutInflater;
   import android.view.View;
   import android.view.ViewGroup;
   import android.widget.Button;
   import android.widget.EditText;
   import java.util.List;
   
   /** * Created by gsolc on 7/11/17. */
   public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
       private List<Data> data;
       private Activity activity;
   
       public MyAdapter(Activity activity, List<Data> data) {
           this.activity = activity;
           this.data = data;
       }
   
   
       @Override    public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
           View itemView = LayoutInflater.from(parent.getContext())
                   .inflate(R.layout.row_with_edit_text, parent, false);
   
           return new ViewHolder(itemView);
       }
   
       @Override    public void onBindViewHolder(final MyAdapter.ViewHolder holder, int position) {
   
           //set positions to listeners        holder.textWatcher.setPosition(position);
           holder.clickListener.setPosition(position);
   
           //set previous data on refreshing        if (data.get(position).getString() != null)
               holder.editText.setText(data.get(position).getString());
           else            holder.editText.setText("");
   
       }
   
   
       @Override    public int getItemCount() {
           return data.size();
       }
   
       public class ViewHolder extends RecyclerView.ViewHolder {
   
           //create objects        final public EditText editText;
           MyTextWatcher textWatcher;
           MyClickListener clickListener;
           public Button btnDelete;
   
           public ViewHolder(View itemView) {
               super(itemView);
   
               //initialize objects            editText = itemView.findViewById(R.id.editText);
               btnDelete = itemView.findViewById(R.id.btnDelete);
   
               //initialize listeners            textWatcher = new MyTextWatcher(editText);
               clickListener = new MyClickListener();
   
               //add listeners            editText.addTextChangedListener(textWatcher);
               btnDelete.setOnClickListener(clickListener);
   
           }
       }
   
       //create a text change listener    public class MyTextWatcher implements TextWatcher {
           private EditText editText;
           private int position;
   
           public void setPosition(int position) {
               this.position = position;
           }
   
           public MyTextWatcher(EditText editText) {
               this.editText = editText;
           }
   
           @Override        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
   
           }
   
           @Override        public void onTextChanged(CharSequence s, int start, int before, int count) {
   
               //add data into data list            data.get(position).setString(s + "");
           }
   
           @Override        public void afterTextChanged(Editable s) {
   
           }
       }
   
       //Create a listener to remove any edittext    public class MyClickListener implements View.OnClickListener {
           private int position;
   
           public void setPosition(int position) {
               this.position = position;
           }
   
           @Override        public void onClick(View view) {
   
               //remove and notify            data.remove(position);
               notifyDataSetChanged();
           }
       }
   }

   
   
   
   

   Create row of adapter row_with_edit_text.xml file and update it-

   
   

   
   

   <?xml version="1.0" encoding="utf-8"?><android.support.constraint.ConstraintLayout 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">
   
       <LinearLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:orientation="horizontal">
   
           <EditText            android:id="@+id/editText"            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:layout_weight="1"            android:hint="Enter Text "            android:inputType="text" />
   
           <Button            android:id="@+id/btnDelete"            android:layout_width="40dp"            android:layout_height="match_parent"            android:background="@android:drawable/ic_delete" />
   
       </LinearLayout>
   
   
   </android.support.constraint.ConstraintLayout>

   
   

   
   

   Open your main_activity.xml file and update it-

   
   

   
   

   <?xml version="1.0" encoding="utf-8"?><android.support.constraint.ConstraintLayout 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="com.pankaj.gsolc.edittextinadaptersdemo.MainActivity">
   
       <LinearLayout        android:layout_width="match_parent"        android:layout_height="match_parent"        android:orientation="vertical">
   
           <Button            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:onClick="addOneMore"            android:text="Add One More" />
   
           <android.support.v7.widget.RecyclerView            android:id="@+id/recyclerView"            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:layout_weight="1"            android:scrollbars="vertical" />
   
           <Button            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:onClick="showData"            android:text="Show entered data" />
   
   
       </LinearLayout>
   
   </android.support.constraint.ConstraintLayout>

   
   

   
   
5. All the application development process with Edittext in list has completed, Now run the app and look the screen.
