Basic Example

You can create your own buttons using the Button component.

Button(
    onClick = { /* TODO */ },
    backgroundColor = Color(0xFFFFFFFF),
    contentColor = Color(0xFF020817),
    contentPadding = PaddingValues(horizontal = 16.dp, vertical = 12.dp),
    shape = RoundedCornerShape(12.dp),
) {
    Text("Submit")
}

Styling

The Button renders nothing on the screen by default. It handles all accessibility semantics for you and comes with opinionated styling options, which covers most button needs out of the box.

The shape of the button is used to clip the button for you, so that the touch indicator within the bounds of the button.

The borderColor and borderWidth parameters place a border to the button. These take the given shape into consideration as opposed to using the respective Modifier alone.

The backgroundColor sets the color of the button's surface.

The contentColor specifies the color to use for the button's content. Components such as Text, Text Field, Icon will use this color to render their content.

The contentPadding parameter places padding within the bounds of the button. Using the Modifier.padding() modifier will cause the button to have a visual margin instead, due to the way of ordering Modifiers in compose works.

The Button component lays its contents horizontally and centers its contents horizontally and vertically. 

Button(
    onClick = { /* TODO */ },
    backgroundColor = Color(0xFFFFFFFF),
    contentColor = Color(0xFF020817),
    contentPadding = PaddingValues(horizontal = 16.dp, vertical = 12.dp),
    shape = RoundedCornerShape(12.dp),
) {
    Text("Submit")
}
