Icon Toggle Button in Jetpack Compose

In Jetpack Compose, the Icon Toggle Button is a composable that represents a toggle button with an icon. It allows users to switch between two states, like toggling between like and unlike. Let’s see the Step-by-Step Implementation.

Here’s a Step-by-Step Implementation:

Step 1: Create a New Project in Android Studio

To create a new project in Android Studio, Select Empty Compose Activity. If you do not find this template, try upgrading the Android Studio to the latest version and make sure you select Kotlin as the primary language while creating a New Project.

Step 2: Working with the IconToggleButtonActivity.kt file

Go to the IconToggleButtonActivity.kt file and refer to the following code. Below is the code for the IconToggleButtonActivity.kt file.

class IconToggleButtonActivity : ComponentActivity() {
    
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            JetpackComposeSeriesTheme {
                // A surface container using the 'background' color from the theme
                Surface(
                    modifier = Modifier.fillMaxSize(),
                    color = MaterialTheme.colorScheme.background
                ) {

                    LikeUnlikeWithIconToggle()
                }
            }
        }
    }
}

@SuppressLint("UnusedTransitionTargetStateParameter")
@Preview
@Composable
fun LikeUnlikeWithIconToggle() {

    val checkState = remember { mutableStateOf(false) }

    Column(
        Modifier
            .fillMaxSize()
            .fillMaxHeight()
            .fillMaxWidth(),
    horizontalAlignment = Alignment.CenterHorizontally,
    verticalArrangement = Arrangement.Center)

    {

        Text(text = if(checkState.value){
            "Like"
        } else{
            "Unlike"
        },
            fontSize = 30.sp
        )

        Spacer(modifier = Modifier.height(16.dp))

        IconToggleButton(
            checked = checkState.value ,
            onCheckedChange = {
                checkState.value = !checkState.value
            }) {

            val transition = updateTransition(targetState = checkState.value, label = "")

            val myTint by transition.animateColor(label = "") { isChecked ->
                if (isChecked){
                    Color.Red
                } else{
                    Color.Black
                }
            }

            val mySize by transition.animateDp(
                label = "",
                transitionSpec = {
                    keyframes {
                        durationMillis = 250
                        120.dp at 0 with LinearOutSlowInEasing
                        125.dp at 30 with FastOutLinearInEasing
                    }
                }
            )
            {100.dp}

            Icon(
                imageVector = if (checkState.value) {
                    Icons.Filled.Favorite
                } else {
                    Icons.Filled.FavoriteBorder
                },
                contentDescription = "",
                modifier = Modifier.size(mySize),
                tint = myTint
            )
        }
    }
}

Now run your application to see the output of the Icon Toggle Button in Jetpack Compose.
