Feeling really dumb. Can't get text to center inside of a row. Code inside the thread.

[Colton Idle]

Row() {
        Spacer(
            modifier = Modifier
                .height(500.dp)
                .aspectRatio(4 / 3f)
                .background(aColorValue)
        )
        Text(
            text = "one",
            Modifier
                .fillMaxHeight(),
            color = MyTheme.colors.one,
        )
}

Using the debug option on my device called "show layout bounds" it looks like the height of the text doesn't actually meet the 500.dp of the spacer size that I expected so I think that's the root of the issue and why textAlign = TextAlign.CENTER isn't working (when I add it). In the snippet above I just am trying to get the height bounds of Text to match the spacer.

Do you actually want the text to be 500.dp high? Or you want the text to be centered vertically inside the 500.dp space? If the latter, you probably instead want:

Text(
    modifier = Modifier.fillMaxHeight().wrapContentHeight()
)

@Louis Pullen-Freilich [G] I figured that I do actually want to text to have a 500dp height, so that I can use textAlign = TextAlign.CENTER

But all of this is very reminicent of the whole 2 gravity options in xml.

So I guess option 1:
Get Text height to be 500 (match the spacer height) and set text.align = Center

Option 2:
Don't modify the text height, but somehow align it vertically

I'm not sure what you want exactly, but the following should show the text after the spacer so that it is centered

Row(verticalAlignment = Alignment.CenterVertically) {
    Spacer(
        modifier = Modifier
            .height(500.dp)
            .aspectRatio(4 / 3f)
            .background(aColorValue)
    )
    Text(
        text = "one",
        color = MyTheme.colors.one,
    )
}

@Louis Pullen-Freilich [G] that method did not work unfortunately.

[Colton Idle]

@Kari Kähkönen thanks that worked, but I actually don't want the entire row to be aligned cetered vertically, as I have another piece of text that comes next in the row and I want it to be placed at the top.

If anyone knows how to center just one piece of text in it's parent that would be awesome

[Louis Pullen-Freilich [G]]

Isn't textAlign only for horizontal alignment? I'm not sure how it relates to vertical alignment in your example, why do you need the text to still be 500.dp high?

[Kari Kähkönen]

To limit centering to the text only, this should work:

Row {
    Spacer(
        modifier = Modifier
            .height(500.dp)
            .aspectRatio(4 / 3f)
            .background(aColorValue)
    )
    Text(
        text = "one",
        color = MyTheme.colors.one,
        modifier = Modifier.align(Alignment.CenterVertically)
    )
}

The align for the modifier comes from RowScope so Android Studio probably doesn't currently show autocomplete for it. But it does exist.

[Colton Idle]

@Kari Kähkönen AHHH. THAT WORKED.

Android Studio doesn't autofill Modifier.align so I didn't think it would work. Just coding it anyway makes it work. NICE!
