I'm creating an app to studies and I got an "error". I looked for help and saw some posts here and on another sites, but nothing works to me.
The last item from a Composable Row is going off the width view when the body text is "larger", as you can see here. I can click in the item, but it's invisible:

import com.example.cleanarchtodo.ui.theme.CleanArchToDoTheme
@Composable
fun ToDoCard(
modifier: Modifier = Modifier,
text: String = "",
checked: Boolean = false,
onCheckedChange: () -> Unit,
) {
ElevatedCard(
modifier = modifier
.fillMaxWidth()
.padding(
vertical = 4.dp,
horizontal = 12.dp
),
elevation = CardDefaults.cardElevation(
defaultElevation = 8.dp
)
) {
Row(modifier = Modifier
.fillMaxWidth(),
verticalAlignment = Alignment.Top,
horizontalArrangement = Arrangement.Start
) {
Checkbox(
checked = checked,
onCheckedChange = { onCheckedChange() }
)
Text(
text = text,
fontSize = 20.sp,
maxLines = 3,
overflow = TextOverflow.Ellipsis
)
Spacer(modifier = Modifier.weight(1f))
IconButton(
onClick = { }
) {
Icon(
imageVector = Icons.Default.Delete,
contentDescription = "Delete ToDo"
)
}
}
}
}
@Preview(
showBackground = true
)
@Composable
fun PreviewToDoCard() {
CleanArchToDoTheme {
ToDoCard(
text = "Buy bananas Buy bananas Buy bananas",
onCheckedChange = {}
)
}
}
Somebody can help me?
Text
widget grows in size to accomodate the size of the text inside it, until it runs out of the parent width. With a very long text like in your case, no space is left for the button to the right
To fix this, you can add Modifier.weight(1f)
to your Text, so it takes up all free space, but is laid out after all other elements, including the button. Also with this approach, you can drop the Spacer(Modifier.weight(1f)
after the Text
, because the new Text
basically combines these two functions
@Composable
fun ToDoCard(
modifier: Modifier = Modifier,
text: String = "",
checked: Boolean = false,
onCheckedChange: () -> Unit,
) {
ElevatedCard(
modifier = modifier
.fillMaxWidth()
.padding(
vertical = 4.dp,
horizontal = 12.dp
),
elevation = CardDefaults.cardElevation(
defaultElevation = 8.dp
)
) {
Row(modifier = Modifier
.fillMaxWidth(),
verticalAlignment = Alignment.Top,
horizontalArrangement = Arrangement.Start
) {
Checkbox(
checked = checked,
onCheckedChange = { onCheckedChange() }
)
Text(
text = text,
fontSize = 20.sp,
maxLines = 3,
overflow = TextOverflow.Ellipsis,
textAlign = TextAlign.Start,
modifier = Modifier.weight(1f),
)
IconButton(
onClick = { }
) {
Icon(
imageVector = Icons.Default.Delete,
contentDescription = "Delete ToDo"
)
}
}
}
