How to align different elements inside a Button in Jetpack Compose?

Question

I am trying to build the following component,

Following is my code,

Button(onClick = { /*TODO*/ }, modifier = Modifier.fillMaxWidth()) {
    Image(painter = painterResource(id = R.drawable.ic_check_circle) , contentDescription = "")
    Text(text = "John Doe", textAlign = TextAlign.Start)
    Image(painter = painterResource(id = R.drawable.ic_arrow_forward), contentDescription = "",
        alignment = Alignment.TopEnd)
}

Answer 1

You can use Spacer:

1. Modifier.width(10.dp) will give you static size.

2. Modifier.weight(1f)) will fill all available space.

Button(onClick = { /*TODO*/ }, modifier = Modifier.fillMaxWidth()) {
    Image(painter = painterResource(id = R.drawable.ic_undo) , contentDescription = "")
    Spacer(modifier = Modifier.width(10.dp))
    Text(text = "John Doe")
    Spacer(modifier = Modifier.weight(1f))
    Image(painter = painterResource(id = R.drawable.ic_redo), contentDescription = "")
}

Wrap the components inside your button compose function with a Row and set the horizontalArrangement to Arrangement.SpaceBetween. See the modified version of your code snippet below.

       Button(onClick = { /*TODO*/ }, modifier = Modifier.fillMaxWidth()) {
    Row(modifier = Modifier
        .align(alignment = Alignment.CenterVertically)
        .fillMaxWidth(0.9f)) {
        Image(painter = painterResource(id = R.drawable.ic_baseline_subject_24),
            contentDescription = "", alignment = Alignment.CenterStart)
        Spacer(modifier = Modifier.width(10.dp))
        Text(text = "John Doe", textAlign = TextAlign.Start, modifier = Modifier.align(alignment = Alignment.CenterVertically))
    }
    Image(painter = painterResource(id = R.drawable.ic_baseline_subject_24),
        contentDescription = "")
}

I made an alternative that closely matches your layout using ConstraintLayout.

Put in your build.gradle file (module scope inside) inside dependencies:

// To use constraint layout in compose
implementation "androidx.constraintlayout:constraintlayout-compose:1.0.0-beta02"

NOTE: I'm using icons provided by android studio itself, remember to use yours if they are custom icons. To do this just change the id parameter of painterResource referring to the appropriate drawables.

In your compose function that displays the button, use the following code:

Button(
    modifier = Modifier
        .fillMaxWidth(),
    shape = RoundedCornerShape(50),
    colors = ButtonDefaults.buttonColors(
        backgroundColor = Color(0xFF847EBA),
        contentColor = Color.White
    ),
    contentPadding = PaddingValues(horizontal = 4.dp),
    onClick = {}
) {
    ConstraintLayout(modifier = Modifier.fillMaxWidth()) {
        val (startIcon, text, endIcon) = createRefs()
        Image(
            modifier = Modifier.constrainAs(startIcon) {
                start.linkTo(parent.start)
            },
            painter = painterResource(id = R.drawable.ic_check_circle_outline),
            contentDescription = null
        )
        Text(
            modifier = Modifier.constrainAs(text) {
                start.linkTo(startIcon.end, margin = 8.dp)
                bottom.linkTo(parent.bottom)
                top.linkTo(parent.top)
            },
            text = "John Doe"
        )
        Image(
            modifier = Modifier.constrainAs(endIcon) {
                end.linkTo(parent.end)
            },
            painter = painterResource(id = R.drawable.ic_navigate_next),
            contentDescription = null
        )
    }
}

The content of the Button is a RowScope.
Just apply the weight modifier to the Text composable:

Button(onClick = { /*TODO*/ }, modifier = Modifier.fillMaxWidth()) {
    Image()
    Spacer(modifier = Modifier.width(10.dp))
    Text(text = "John Doe",modifier = Modifier.weight(1f))
    Image()
}
