    Pada kesempatan kali ini kita akan diajak untuk membuat sebuah kalkulator sederhana dengan hasil sebagai berikut.

    Adapun code dari aplikasi ini dapat dilihat dari file MainActivity.kt berikut.

	package com.example.mycalculator
	import android.os.Bundle
	import android.widget.Toast
	import androidx.activity.ComponentActivity
	import androidx.activity.compose.setContent
	import androidx.compose.foundation.layout.Column
	import androidx.compose.foundation.layout.Row
	import androidx.compose.foundation.layout.Spacer
	import androidx.compose.foundation.layout.fillMaxSize
	import androidx.compose.foundation.layout.height

	import androidx.compose.material3.Button

	import androidx.compose.material3.Surface
	import androidx.compose.material3.Text
	import androidx.compose.material3.TextField
	import androidx.compose.runtime.Composable
	import androidx.compose.ui.Modifier
	import androidx.compose.ui.tooling.preview.Preview
	import com.example.mycalculator.ui.theme.MyCalculatorTheme
	import androidx.compose.runtime.*
	import androidx.compose.ui.unit.dp
	class MainActivity : ComponentActivity() {
	override fun onCreate(savedInstanceState: Bundle?) {
	super.onCreate(savedInstanceState)
	setContent {
	var num1 by remember {
	mutableStateOf(value = "0")
	}
	var num2 by remember {
	mutableStateOf(value = "0")
	}
	Column {
	TextField(value = num1, onValueChange = {
	num1 = it
	})
	TextField(value = num2, onValueChange = {
	num2 = it
	})
	Spacer(modifier = Modifier.height(32.dp))
	Row {
	Button(onClick = {
	var result = num1.toInt() + num2.toInt()
	Toast.makeText(applicationContext, "Result is $result", Toast.LENGTH_SHORT).show()
	}) {
	Text(text = "Add")
	}
	Spacer(modifier = Modifier.width(16.dp))
	Button(onClick = {
	var result = num1.toInt() - num2.toInt()
	Toast.makeText(applicationContext, "Result is $result", Toast.LENGTH_SHORT).show()
	}) {
	Text(text = "Sub")
	}
	Spacer(modifier = Modifier.width(16.dp))
	Button(onClick = {
	var result = num1.toInt() * num2.toInt()
	Toast.makeText(applicationContext, "Result is $result", Toast.LENGTH_SHORT).show()
	}) {
	Text(text = "Mul")
	}
	Spacer(modifier = Modifier.width(16.dp))
	Button(onClick = {
	var result = num1.toInt() / num2.toInt()
	Toast.makeText(applicationContext, "Result is $result", Toast.LENGTH_SHORT).show()
	}) {
	Text(text = "Div")
	}
	}
	}
	}
	}
	}
