How to add Text with all Caps in Android Jetpack Compose

Styling text is an important aspect of designing mobile apps. Sometimes, we display all text in capital letters to show the significance. Let’s learn how to capitalize text in Jetpack Android.

The Text composable doesn’t have a built-in property to change text case. Hence, we use the Kotlin function uppercase() for this purpose. See the code snippet given below.

@Composable
fun TextExample() {
    Text(text = ("This is an example of text with caps all").uppercase(),
        fontSize = 24.sp)
}

Following is the output.

        super.onCreate(savedInstanceState)
        setContent {
            MyApplicationTheme {
                Surface(
                    modifier = Modifier.fillMaxSize(),
                    color = MaterialTheme.colorScheme.background
                ) {
                    Column {
                        TextExample()
                    }
                }
            }
        }
    }
}

@Composable
fun TextExample() {
    Text(text = ("This is an example of text with caps all").uppercase(),
        fontSize = 24.sp)
}
