Aplikasi Roll Dadu

Untuk tugas kali ini, kita bakalan membuat aplikasi roll dadu sederhana menggunakan Empty Activity Project.

Berikut Sumber Kode :

	package com.example.dadu
	import android.os.Bundle
	import androidx.activity.ComponentActivity
	import androidx.activity.compose.setContent
	import androidx.compose.foundation.layout.Column
	import androidx.compose.foundation.layout.fillMaxSize
	import androidx.compose.foundation.layout.wrapContentSize
	import androidx.compose.material3.Text
	import androidx.compose.runtime.Composable
	import androidx.compose.ui.Modifier
	import androidx.compose.ui.tooling.preview.Preview
	import com.example.dadu.ui.theme.DaduTheme
	import androidx.compose.ui.Alignment
	import androidx.compose.material3.Button
	import androidx.compose.ui.res.painterResource
	import androidx.compose.ui.res.stringResource
	import androidx.compose.foundation.Image
	import androidx.compose.foundation.layout.Spacer
	import androidx.compose.foundation.layout.height
	import androidx.compose.ui.unit.dp
	import androidx.compose.runtime.mutableStateOf
	import androidx.compose.runtime.remember
	import androidx.compose.runtime.getValue
	import androidx.compose.runtime.setValue
	class MainActivity : ComponentActivity() {
	override fun onCreate(savedInstanceState: Bundle?) {
	super.onCreate(savedInstanceState)
	setContent {
	DaduTheme {
	DiceRollerApp()
	}
	}
	}
	}
	@Preview(showBackground = true)
	@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()
	)
	Spacer(modifier = Modifier.height(20.dp))
	Button(onClick = { result = (1..6).random() }) {
	Text(stringResource(R.string.roll))
	}
	}
	}
