class MainActivity : ComponentActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            DiceRollerTheme {
                Surface(
                    modifier = Modifier.fillMaxSize(),
                    color = MaterialTheme.colorScheme.background
                ) {
                    DiceRollerApp()
                }
            }
        }
    }
}

@Preview
@Composable
fun DiceRollerApp() {
    DiceWithButtonAndImage(modifier = Modifier
        .fillMaxSize()
        .wrapContentSize(Alignment.Center)
    )
}

@Composable
fun DiceWithButtonAndImage(modifier: Modifier = Modifier) {
    var result by remember { mutableStateOf( 1) }
    val imageResource = when(result) {
        1 -> R.drawable.dice_1
        2 -> R.drawable.dice_2
        3 -> R.drawable.dice_3
        4 -> R.drawable.dice_4
        5 -> R.drawable.dice_5
        else -> R.drawable.dice_6
    }
    Column(modifier = modifier, horizontalAlignment = Alignment.CenterHorizontally) {
        Image(painter = painterResource(imageResource), contentDescription = result.toString())

        Button(
            onClick = { result = (1..6).random() },
        ) {
            Text(text = stringResource(R.string.roll), fontSize = 24.sp)
        }
    }
}

Secara sederhana, aksi pengacakan dilakukan oleh perintah onClick = { result = (1..6).random() } di dalam tombol untuk menghasilkan angka acak 1 sampai 6 saat diklik. Angka acak tersebut kemudian digunakan oleh blok when(result) di dalam fungsi DiceWithButtonAndImage untuk secara otomatis mengganti gambar dadu di layar sesuai dengan angka yang didapat.

Strings.xml

<string name="roll">Roll</string>

Tambahkan baris diatas agar dapat memanggil fungsi Roll nya.

Langkah 3: Testing

Click tombol Roll di aplikasi tersebut jika dadu nya berubah secara acak setiap klik maka program sudah berjalan dengan lancar.
