Navigation Drawer -> activity para fragment - java

I'm in trouble, this code is not working.
I think my error is in the class, that has the function of the sum in class check1a4. It should be a 'Fragment'?
I tried searching in some tutorials but I did not find a solution.

Rectangle Area Calculation

I am trying to calculate the rectangle area in my application. I have created a simple layout but for some reason, data is not parsed into the application. I tried to print it in the console but nothing is shown.
This is my Main Class:
package com.example.week3labcode;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
Button calcButton;
EditText number1, number2, resultFinal;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
calcButton = (Button)findViewById(R.id.button1);
number1 = (EditText) findViewById(R.id.edtext1);
number2 = (EditText) findViewById(R.id.edtext2);
resultFinal = (EditText) findViewById(R.id.edtext3);
}
#Override
public void onClick(View v){
if(v == calcButton){
number1 = (EditText) findViewById(R.id.edtext1);
number2 = (EditText) findViewById(R.id.edtext2);
double num1 = Double.parseDouble(number1.getText().toString());
double num2 = Double.parseDouble(number2.getText().toString());
calcRectangle(num1, num2);
}
}
public void calcRectangle(double x, double y){
double result = x * y;
System.out.println(result);
resultFinal = (EditText) findViewById(R.id.edtext3);
resultFinal.setText(Double.toString(result));
System.out.println('H' + result);
}
}
And the following code in my XML file that provides layout for the application:
<?xml version="1.0" encoding="utf-8"?>

You have not set OnClickListener to your Button so calcRectangle() method is never called.
calcButton = (Button)findViewById(R.id.button1);
calcButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
number1 = (EditText) findViewById(R.id.edtext1);
number2 = (EditText) findViewById(R.id.edtext2);
double num1 = Double.parseDouble(number1.getText().toString());
double num2 = Double.parseDouble(number2.getText().toString());
calcRectangle(num1, num2);
}
});
OR
calcButton.setOnClickListener(this);

try the above code your problem was here
final int amount = Integer.parseInt(et.getText().toString());

Why are my views widening and then returning to normal during running of this code?

This is the code.
What more information do i need to put here?
I'm trying to find out why my text and button views are widening and then returning to normal during running of this code.
It keeps saying i need more details so i guess im just gonna talk about some nonsense here.

The error is on one, two, three...nine and information count, human count etc. Here is my fragment file, so why can't I see one, two, three....nine labeled blue? Why is it not recognized? What have I done wrong ? I received the errors after findviewbyid.

When you got this type of error at anywhere and you have import android.R; then just remove import android.R;.
