androidx.compose.ui.autofill

fun ContentType(contentHint: String): ContentType

Create a custom ContentType with contentHint.

This creates a ContentType with the parameter contentHint passed in. This API can be used if the Autofill hint is not present in the list of contentTypes provided by Compose.

For example, ContentType(androidx.autofill.HintConstants.AUTOFILL_HINT_FLIGHT_CONFIRMATION_CODE) can be used to create a new flight confirmation code hint.

@RequiresApi(value = 26)
fun FillableData(booleanValue: Boolean): FillableData

Creates a FillableData instance from a Boolean.

This function is used to wrap a boolean value for autofill purposes, such as the state of a checkbox or a switch. On Android, it creates an AutofillValue that represents a toggle state.

@RequiresApi(value = 26)
fun FillableData(charSequenceValue: CharSequence): FillableData

Creates a FillableData instance from a CharSequence.

This function is used to wrap a text value for autofill purposes. On Android, it creates an AutofillValue that contains the provided text.

@RequiresApi(value = 26)
fun FillableData(intValue: Int): FillableData

Creates a FillableData instance from an Int.

This function is used to wrap an integer value for autofill purposes, such as the selected index in a dropdown menu or spinner. On Android, it creates an AutofillValue that represents a list selection.

fun Modifier.contentType(contentType: ContentType): Modifier

Set autofill hint with contentType.

This applies the contentType to the modifier's semantics, in turn enabling autofill and marking the hint to be associated with this composable. This allows autofill frameworks to provide relevant suggestions to users.

Using contentType is equivalent to simply setting the contentType semantic property, i.e. Modifier.contentType(ContentType.NewUsername) is equivalent to setting Modifier.semantics { contentType = ContentType.NewUsername }.
