How to place items in row and one each above like position absolute with JetpackCompose?

I need to make layout that looks like this:
So I need to position two avatars in row while first avatar is going over second one. Also, icon for back is positioned on top of first avatar. I need basically something like position absolute but can not find how to do this with Jetpack compose.

You can use Box and zIndex to reach this result,
try this code you will get a result like that
Row(
verticalAlignment = Alignment.CenterVertically,
modifier = Modifier
.background(Color.Yellow)
.padding(20.dp)
) {
Box {
Box(
contentAlignment = Alignment.TopStart,
modifier = Modifier
.height(30.dp)
.zIndex(3f)
) {
Icon(
imageVector = Icons.Rounded.ArrowBack,
contentDescription = "ArrowBack",
modifier = Modifier
.size(20.dp)
.clip(RoundedCornerShape(20.dp))
.background(Color.Gray)
.zIndex(2f)
.border(1.dp, Color.White, RoundedCornerShape(20.dp))
.padding(3.dp)
)
}
Box(
contentAlignment = Alignment.Center,
modifier = Modifier
.padding(start = 10.dp)
.size(30.dp)
.clip(RoundedCornerShape(20.dp))
.background(Color.Gray)
.zIndex(2f)
.border(1.dp, Color.White, RoundedCornerShape(20.dp))
.padding(6.dp)
) {
Icon(
imageVector = Icons.Rounded.Person,
contentDescription = "Person",
modifier = Modifier
.size(30.dp)
)
}
Box(
modifier = Modifier
.padding(start = 30.dp)
.size(30.dp)
.clip(RoundedCornerShape(20.dp))
.background(Color.Gray)
.zIndex(1f)
.border(1.dp, Color.White, RoundedCornerShape(20.dp))
.padding(6.dp)
) {
Icon(
imageVector = Icons.Rounded.Person,
contentDescription = "Person",
modifier = Modifier
.size(30.dp)
)
}
}
Spacer(modifier = Modifier.width(6.dp))
Text(text = "17 other answers")
}

JetPack Compose Button with drawable

How can we achieve this in jetpack compose
I'm doing something like this
Button(
elevation = ButtonDefaults.elevation(
defaultElevation = 0.dp,
pressedElevation = 8.dp,
disabledElevation = 0.dp
),
onClick = { onClick },
shape = RoundedCornerShape(28.dp),
modifier = modifier
.fillMaxWidth()
.shadow(0.dp),
contentPadding = PaddingValues(15.dp),
colors = ButtonDefaults.buttonColors(backgroundColor = Color.White),
border = BorderStroke(1.dp, Color.Grey)
) {
Box(modifier = modifier.fillMaxWidth(),
contentAlignment = Alignment.Center) {
Icon(
imageVector = imageVector,
modifier = Modifier
.size(18.dp),
contentDescription = "drawable icons",
tint = Color.Unspecified
)
Spacer(modifier = Modifier.width(10.dp))
Text(
text = buttonText,
color = Color.Black,
textAlign = TextAlign.Center
)
}
}
So as you can see the Google logo is just left of the text I need it at the start of the box so how can I do this.

You can use align(Alignment.CenterStart) on the Icon's Modifier parameter to center the icon around the start of the Box Composable. This alignment will have priority over the Box's alignment parameter.
You can also delete the Spacer composable because the Box layout children are stacked one on top of the other in the composition order. So the Spacer composable is basically laying below the Text composable in the center.
If you want some space between the Icon and the Text, you could use some padding around the Icon instead.
Try this (It worked for me) :
Box(modifier = modifier.fillMaxWidth(),
contentAlignment = Alignment.Center) {
Icon(
imageVector = imageVector,
modifier = Modifier
.size(18.dp)
.align(Alignment.CenterStart),
contentDescription = "drawable icons",
tint = Color.Unspecified
)
Text(
text = buttonText,
color = Color.Black,
textAlign = TextAlign.Center
)
}

#Composable
fun GoogleButton(
modifier: Modifier = Modifier,
imageVector: ImageVector,
buttonText: String,
onClick: (isEnabled: Boolean) -> Unit = {},
enable: Boolean = true,
backgroundColor: Color,
fontColor: Color,
) {
Button(
onClick = { onClick(enable) },
modifier = modifier
.fillMaxWidth()
.shadow(0.dp)
.noInteractionClickable(enabled = false) { onClick(enable) },
elevation = ButtonDefaults.elevation(
defaultElevation = 0.dp,
pressedElevation = 0.dp,
hoveredElevation = 0.dp,
focusedElevation = 0.dp
),
shape = RoundedCornerShape(28.dp),
contentPadding = PaddingValues(15.dp),
colors = ButtonDefaults.buttonColors(
backgroundColor = backgroundColor,
contentColor = fontColor
),
border = BorderStroke(1.dp, MaterialTheme.colors.getButtonBorderStroke)
) {
Box(
modifier = Modifier
.fillMaxWidth(),
contentAlignment = Alignment.Center
) {
Row(
modifier = Modifier
.fillMaxWidth()
.align(Alignment.CenterStart)
) {
Spacer(modifier = Modifier.width(4.dp))
Icon(
imageVector = imageVector,
modifier = Modifier
.size(18.dp),
contentDescription = "drawable_icons",
tint = Color.Unspecified
)
}
Text(
modifier = Modifier.align(Alignment.Center),
text = buttonText,
color = MaterialTheme.colors.loginButtonTextColor,
textAlign = TextAlign.Center,
fontSize = 16.sp,
fontFamily = FontFamily(
Font(
R.font.roboto_medium
)
)
)
}
}
}

As suggested in other answers you can wrap the content with a Box.
As alternative you can simply use the RowScope of the Button without any container.
Just apply a weight(1f) modifier to the Text and an offset(x=- iconWidth/2).
Something like:
Button(
//....
) {
Icon(
imageVector = imageVector,
modifier = Modifier.size(iconWidth),
contentDescription = "drawable icons",
tint = Color.Unspecified
)
Text(
text = "Button",
color = Color.Black,
textAlign = TextAlign.Center,
modifier = Modifier
.weight(1f)
.offset(x= -iconWidth/2) //default icon width = 24.dp
)
}
If you want to use a Box, remove the contentAlignment = Alignment.Center in the Box and use:
Box(modifier = Modifier.fillMaxWidth()) {
Icon( /* ..... */ )
Text(
modifier = Modifier.fillMaxWidth(),
text = "buttonText",
textAlign = TextAlign.Center
)
}

Box doesn't provide bounds, so for longer texts, it causes overlapping. Row works better for me. Also, you can use Spacer here which is not possible for Box. In my case, I have used spacedBy as a replacement for Spacer:
Row(
modifier = Modifier.fillMaxWidth(),
horizontalArrangement = Arrangement.spacedBy(16.dp),
verticalAlignment = Alignment.CenterVertically
) {
Icon(
painter,
contentDescription = null
)
Box(
modifier = Modifier.weight(1F),
contentAlignment = Alignment.Center
) {
Text(buttonText)
}
}

Box(contentAlignment = Center){
Icon(Modifier.align(CenterStart))
Text()
}

Jetpack Compose Textfield Alignment

I'm new to jetpack compose. I want to start typing from TextField's centervertically-start
position but I can't put "Example" to center
vertically-start position.
Row(
modifier = Modifier
.fillMaxWidth()
.height(50.dp)
.shadow(5.dp)
.background(Color.Yellow),
) {
BasicTextField(
value = text,
onValueChange = {onvalueChange(it)},
modifier = Modifier.weight(10f).background(Color.Blue).fillMaxSize(),
singleLine = true,
textStyle = LocalTextStyle.current.copy(
textAlign = TextAlign.Center
)
)
Image(painter = painterResource(id = R.drawable.ic_baseline_search_24),
contentDescription = "Search",
modifier = Modifier.weight(2f).fillMaxSize()
)
This is my code
And this is what I want to do.

Row has a verticalAlignment for this. Also, if you want your TextField left align like the picture, remove the textAlign (or change it but it default to start)
Row(
modifier = Modifier
.fillMaxWidth()
.height(50.dp)
.shadow(5.dp)
.background(Color.Yellow),
verticalAlignment = Alignment.CenterVertically,
) {
BasicTextField(
value = text,
onValueChange = {onvalueChange(it)},
modifier = Modifier.weight(10f).background(Color.Blue).fillMaxSize(),
singleLine = true,
)
Image(painter = painterResource(id = R.drawable.ic_baseline_search_24),
contentDescription = "Search",
modifier = Modifier.weight(2f).fillMaxSize()
)
}

Use background box to control, please try:
Row(
modifier = Modifier
.fillMaxWidth()
.height(50.dp)
.shadow(5.dp)
.background(Color.Yellow),
) {
Box(Modifier.weight(10f).background(Color.Blue).fillMaxSize(),contentAlignment = CenterStart){
BasicTextField(
value = text,
onValueChange = { onvalueChange(it) },
modifier = Modifier.wrapContentHeight(
Alignment.CenterVertically),
singleLine = true,
textStyle = LocalTextStyle.current.copy(
textAlign = TextAlign.Start
)
)
}
Image(
Icons.Filled.Search,
contentDescription = "Search",
modifier = Modifier.weight(2f).fillMaxSize()
)
}

Android compose text overflow weight is not work

RI am developing an Android app using jetpack compose.
Here is a very basic UI component:
I want to add a button on the right side.
But if the name is very long, the button is gone.
My code is here:
Row(
modifier = Modifier.fillMaxWidth(),
horizontalArrangement = Arrangement.SpaceBetween,
verticalAlignment = Alignment.CenterVertically
) {
Row(
verticalAlignment = Alignment.CenterVertically
) {
Image(
painter = rememberImagePainter(data = profileImg),
contentDescription = null,
modifier = Modifier
.size(56.dp)
.clip(CircleShape)
)
Column(
verticalArrangement = Arrangement.Center,
modifier = Modifier.weight(1F) // I set the weight in here but it doesn't work.
) {
Text(
text = "very very very very very very very long name",
fontWeight = FontWeight.Bold,
maxLines = 1,
overflow = TextOverflow.Ellipsis,
)
Text(
text = "3 minutes ago",
)
}
}
Row {
Button()
Button()
}
}
How can I show the right button correctly?

You need to actually provide that weight to Row containing your Text & make sure you don't cover the entire width. e.g don't do just 1f.
You can do something like this; (This is done with compose_version = '1.0.1')
#Composable
fun Item() {
Row(
modifier = Modifier.fillMaxWidth(),
horizontalArrangement = Arrangement.SpaceBetween,
verticalAlignment = Alignment.CenterVertically
) {
Row(
verticalAlignment = Alignment.CenterVertically,
modifier = Modifier.weight(0.7f)
) {
Image(
painter = painterResource(R.drawable.ic_launcher_background),
contentDescription = null,
modifier = Modifier
.size(56.dp)
.clip(CircleShape)
)
Column(
verticalArrangement = Arrangement.Center,
) {
Text(
text = "very very very very very very very long name",
fontWeight = FontWeight.Bold,
maxLines = 1,
overflow = TextOverflow.Ellipsis,
)
Text(
text = "3 minutes ago",
)
}
}
Button(
onClick = {}, modifier = Modifier
.wrapContentWidth()
.weight(0.3f)
) {
Text(text = "Button")
}
}
}
Output:

Here is a working code (I've removed useless Row, it's simpler that way)
#Composable
fun Test() {
Row(
modifier = Modifier.fillMaxWidth,
horizontalArrangement = Arrangement.spacedBy(5.dp),
verticalAlignment = Alignment.CenterVertically
) {
Image(
painter = rememberImagePainter(data = profileImg),
contentDescription = null,
modifier = Modifier
.size(56.dp)
.clip(CircleShape)
)
Column(
verticalArrangement = Arrangement.Center,
modifier = Modifier.weight(1f) // I set the weight in here but it doesn't work.
) {
Text(
text = "very very very very very very very long name",
fontWeight = FontWeight.Bold,
maxLines = 1,
overflow = TextOverflow.Ellipsis,
)
Text(
text = "3 minutes ago",
)
}
Button(onClick = { }) {
Text(text = "Btn1")
}
Button(onClick = { }) {
Text(text = "Btn2")
}
}
}

Even though the other question are right I am going to explain your mistake, to better understand what is going on.
So you need:
A Row() which will contain those 3:
Image
Column
and a Row with the two buttons
In other words something like:
Row() {
Image()
Column(weight:1f)
Row()
}
Your mistake is that you created a Row with two other Rows without weights and you get this weird output.
So if you simply delete your outer Row and move your Row of buttons like so it will work:

Items do not have dynamic height inside Scrollable Columns in Compose

Items seem to have fixed height inside Column.
I'm trying to show multiple rows of dynamic height inside the column, and the items of those rows also having dynamic height.
I have tried wrapping the Column inside the box, but that doesn't work.
Box {
Column(
modifier = Modifier
.fillMaxSize()
) {
Image(
painter = painterResource(id = R.drawable.background_home),
contentDescription = "",
contentScale = ContentScale.FillBounds,
modifier = Modifier
.fillMaxWidth()
.fillMaxHeight(0.3f)
)
Spacer(modifier = Modifier.height(10.dp))
List()
Spacer(modifier = Modifier.height(10.dp))
Row(
modifier = Modifier
.fillMaxWidth()
.wrapContentHeight()
.padding(10.dp)
) {
Text(
text = "My Days",
style = TextStyle(
fontStyle = FontStyle.Normal,
fontFamily = FontFamily.Monospace,
fontWeight = FontWeight.Bold
)
)
Text(text = "Red Sun")
}
MyAnotherList(
Modifier
.fillMaxWidth()
.fillMaxHeight(0.6f)
.padding(10.dp)
.horizontalScroll(rememberScrollState())
)
Spacer(modifier = Modifier.height(10.dp))
Row(
modifier = Modifier
.fillMaxWidth()
.wrapContentHeight()
.padding(10.dp)
) {
Text(
text = "My Other Days",
style = TextStyle(
fontStyle = FontStyle.Normal,
fontFamily = FontFamily.Monospace,
fontWeight = FontWeight.Bold
)
)
Text(text = "Blue Sun")
}
MyOtherList()
}
TopBar()
}
Trying to achieve something like this, but all the rows will have dynamic height
Is there a way that I can provide dynamic height to the items inside scrollable columns.
