I want to create a converter that calculates the temperature

I just added some details to the code and it executes me but when I want to enter data in the edit the application is closed. I appreciate your support.

This is my code.

package com.example.android.toolsmoises;

import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.text.Editable; import android.text.TextWatcher; import android.widget.EditText;

public class Temperature extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_temperatura);
    conversor();

}

private void conversor() {
    final EditText editText1 =findViewById(R.id.celsius);
    final EditText editText2 =findViewById(R.id.farenhait);
    final EditText editText3 =findViewById(R.id.kelvin);

    editText1.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

        }

        @Override
        public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {

        }

        @Override
        public void afterTextChanged(Editable editable) {

            editText2.setText((int) (Integer.parseInt(editText1.getText().toString())/1.8+32));
            editText3.setText((int) (Integer.parseInt(editText1.getText().toString())/1.8+32));
        }
    });

    editText2.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

        }

        @Override
        public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {

        }

        @Override
        public void afterTextChanged(Editable editable) {

            editText1.setText((int) (Integer.parseInt(editText2.getText().toString())*1.8+32));
            editText3.setText((int) (Integer.parseInt(editText2.getText().toString())*1.8+32));
        }
    });

    editText3.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

        }

        @Override
        public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {

        }

        @Override
        public void afterTextChanged(Editable s) {

            editText1.setText((int) (Integer.parseInt(editText2.getText().toString())*1.8+32));
            editText3.setText((int) (Integer.parseInt(editText2.getText().toString())*1.8+32));
        }
    });
}

}

and this is the layout:

<TextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Conversor de temperatura"
    android:textSize="30dp"
    android:textAlignment="center"
    android:layout_margin="10dp"/>

<EditText
    android:id="@+id/celsius"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="celsius"
    android:textAlignment="center"/>

<EditText
    android:id="@+id/farenhait"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="fahrenheit"
    android:textAlignment="center"/>

<EditText
    android:id="@+id/kelvin"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="kelvin"
    android:textAlignment="center"/>
