I have a Row layout with two Composables inside:
Text that should wrap itself width and take as much space as possible when content is lengthy
Image that has to be present every time on the right side of Text
To achieve both, I'm currently using weight(weight = 1f, fill = false) for Text Composable. And it works fine for single line content. However, it creates an issue with line breaking and wrapping multiline text. For clearer view, I've added background(Color.Yellow) and some long words. See reference code:
Row {
Text(
text = "This is the message with quite super-unprecedented words",
modifier = Modifier
.background(Color.Yellow)
.weight(
weight = 1f,
fill = false
)
)
Image(
painter = painterResource(R.drawable.image),
contentDescription = null
)
}
And the result looks like this:
Is it possible to remove the padding at the end of Text so Image could fit closely to Text in multiline case as well? Or any other ideas how to achieve this? I've already taken a look on softWrap parameter for Text and requireSize for Image but with no big luck.

I have a a text element with an icon to its right, both wrapped in a Row. The text has a 1.0f weight with fill = false. When a word wraps to the next line, the text has some padding at the end of it causing the icon to be too far apart from it. This is what it looks like:
App Example
Here is the code:
Row(
modifier = Modifier.width(150.dp)
) {
Text(
"John Doe John Doe John Doe",
modifier = Modifier.weight(1.0f, fill = false).background(Color.Green)
)
Icon(
imageVector = Icons.Default.Done,
contentDescription = "",
)
}
How do I make it so the text's width wraps itself without adding that extra spacing?
This is a normal behavior. It happens because you set weight for your Text and a width modifier for your Row.
It's kind of unavoidable when setting a specific width or height. It may happen even if you set weight for both Composables inside the Row (0.1f and 0.9f). Because the word can't fit in the remaining space but the Composable must fill the Row
You set the row width to 150.dp and when your Text has a weight modifier, it fills the row even if a word in your Text composable doesn't fit in the line.
I have a Lazy column like so
LazyColumn(
modifier = Modifier
.fillMaxWidth()
.height(gridMultiple(i = 15) * data.size)
.padding(vertical = gridMultiple(i = 2)),
verticalArrangement = Arrangement.spacedBy(gridMultiple(i = 2)),
userScrollEnabled = false
) {
items(data.size) { index ->
val item = data[index]
ListItem(
item,
editButtonClick = { id -> onEditClick(id) }
)
}
}
and it is encapsulated in an interop composable XML element like so:
<androidx.compose.ui.platform.ComposeView
android:id="#+id/informationList"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
The catch is that the informationList is inside of a ScrollView (XML), and I want the lazy column list to be fully expanded within the scroll view. But I do not know the height that the elements need to be, so I am doing this math here:
.height(gridMultiple(i = 15) * data.size)
But it uses either too much space or not enough. So either elements get cut off, or they have a lot of empty space at the end. I want to use exactly as much space as the LazyColumn needs. If I set the height to be wrapping, I get an exception that the lazy column has an infinite possible height and must have a height specified. There must be a way to do this. I know that the max amount of elements that can ever be in the lazy column is limited to about 10.
That will defeat the whole purpose of LazyColumn. The lazy part just won't work when you use it like that. You could just go with normal Column and it would make no difference at all in terms of performance. Especially with 10 items, with such number the LazyColumn is huge overkill. Bonus for your case - Column supports wrapContentHeight().
TLDL - just use Column with wrapContentHeight() and it should be just fine
I am building a chat screen using Jetpack Compose, Each message draw a column that takes the full width of the screen, and inside the column, I draw a time Text at the center of the screen width, and below the time I draw a message Text that takes between 0 and 0.75 of the screen width. If the message width is bigger than 0.75 of the screen width it takes multiple lines, but I notice that the space at soft line break is very big and ugly, how can I reduce it? I want to achieve the same result in the left image below.
#Composable
fun MessageRow() {
Column {
// here goes time then a surface contains message
Surface(
color = MaterialTheme.colors.background,
modifier = Modifier
.widthIn(0.dp, 265.dp)
) {
Text(
text = "I was distraught to attend the meeting.",
color = Color.Black
)
}
}
}
I have a TextField
TextField(
keyboardOptions = KeyboardOptions.Default.copy(
imeAction = ImeAction.Search,
),
keyboardActions = KeyboardActions(
onSearch = {
onSearchTextSubmit(searchText)
},
),
modifier = Modifier.focusRequester(focusRequester),
singleLine = true
)
the I click "Enter" on keyboard the input gets cut from the bottom.
The TextField is inside TopAppBar and I don't set any height or text size explicitly.
Is decreasing text size the only way to make it look good or there is a way to force TextField to adjust its height or text size out of the box?
You need to increase the height of the field by a modifier that looks like this:
modifier = Modifier.height(56.dp), //56 or higher!
Thus, todays options are:
Increase the height of the TextField
Decrease the size of the font
Check the surrounding containers like Card Box Row Column you will find one with a fixed Height it has impact on your composable you should increase that height i was having the same problem i found a card with fixed height 150.dp i change it to 160.dp and it works hope its the same for you
I want to position my own component (say a Text component) vertically so that I can specify the y-offset relative to the bottom of the Text component. How could I do this in Jetpack compose?
So something like
Column {
Text("Something", modifier = Modifier.offset(y=10.dp))
}
But instead of 10dp representing the top y-position of the Text component it would be the bottom y-position. Basically taking into account the height of the Text even if Text size changes. So y = offset.y - height
As I can see it, there's two problems:
The font size can be changed, so I cannot hard code the text height.
I need to know the size of my Text component during composition, but I don't know how to get that.
You could go for custom Composables,
#Composable
fun CustomText(y: Dp){
Layout(content = { Text(text = "Lorem Ipsum") }){measurables, constraints ->
val text = measurables[0].measure(constraints)
layout(constraints.maxWidth, constraints.maxHeight){ //Change these per your needs
text.placeRelative(IntOffset(0, y.value.roundToInt() - text.height))
}
}
}
You could also use a custom Modifier. Check out using the layout modifier
