1. Create the layout file (res/layout/activity_main.xml):

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="16dp"
tools:context=".MainActivity">

<EditText
android:id="@+id/editTextNumber1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Enter Number 1"
android:inputType="numberDecimal"/>

<EditText
android:id="@+id/editTextNumber2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@id/editTextNumber1"
android:layout_marginTop="16dp"
android:hint="Enter Number 2"
android:inputType="numberDecimal"/>

<Button
android:id="@+id/buttonCalculate"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@id/editTextNumber2"
android:layout_marginTop="16dp"
android:text="Calculate"/>
</RelativeLayout>

1. MainActivity.java::

import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

private EditText editTextNumber1, editTextNumber2;
private Button buttonCalculate;

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

editTextNumber1 = findViewById(R.id.editTextNumber1);
editTextNumber2 = findViewById(R.id.editTextNumber2);
buttonCalculate = findViewById(R.id.buttonCalculate);

buttonCalculate.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
calculateAndNavigate();
}
});
}

private void calculateAndNavigate() {
// Get the input numbers
double num1 = Double.parseDouble(editTextNumber1.getText().toString());
double num2 = Double.parseDouble(editTextNumber2.getText().toString());

// Calculate power and average
double powerResult = Math.pow(num1, num2);
double averageResult = (num1 + num2) / 2;

// Create an intent to navigate to ResultActivity
Intent intent = new Intent(this, ResultActivity.class);
intent.putExtra("powerResult", powerResult);
intent.putExtra("averageResult", averageResult);

// Start the ResultActivity
startActivity(intent);
}
}

2. activity_result.xml (layout file for ResultActivity):

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="16dp"
tools:context=".ResultActivity">

<TextView
android:id="@+id/textViewPowerResult"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>

<TextView
android:id="@+id/textViewAverageResult"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/textViewPowerResult"
android:layout_marginTop="16dp"/>
</RelativeLayout>

2. ResultActivity.java:

import android.os.Bundle;
import android.widget.TextView;

import androidx.appcompat.app.AppCompatActivity;

public class ResultActivity extends AppCompatActivity {

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

// Get the results from the intent
double powerResult = getIntent().getDoubleExtra("powerResult", 0.0);
double averageResult = getIntent().getDoubleExtra("averageResult", 0.0);

// Display the results in TextViews
TextView textViewPowerResult = findViewById(R.id.textViewPowerResult);
TextView textViewAverageResult = findViewById(R.id.textViewAverageResult);

textViewPowerResult.setText("Power Result: " + powerResult);
textViewAverageResult.setText("Average Result: " + averageResult);
}
}
