Android jetpack compose Material 3 Unable to align checkbox text
问题
- 如何使文本“Check me”与复选框对齐?
您可以尝试以下修改您的代码来使文本与复选框对齐:
Checkbox(
checked = true,
onCheckedChange = { },
modifier = Modifier.alignByBaseline() // 使用此修饰符来使文本与复选框基线对齐
)
Text(
text = "Check me",
fontWeight = FontWeight.Bold,
fontSize = 18.sp,
textAlign = TextAlign.Left
)
- 如何使文本更靠近复选框?
如果您想使文本更靠近复选框,您可以调整modifier
中的absoluteOffset
值。负值将使文本向左移动,正值将使文本向右移动。例如:
Checkbox(
checked = true,
onCheckedChange = { },
modifier = Modifier.absoluteOffset((-4).dp, 0.dp) // 调整X轴偏移值
)
Text(
text = "Check me",
fontWeight = FontWeight.Bold,
fontSize = 18.sp,
textAlign = TextAlign.Left
)
通过这些修改,您可以尝试调整文本与复选框的对齐和间距以获得您想要的效果。

I am using Android Studio Electric Eel | 2022.1.1.
I am fairly new. I was trying out the checkbox in Compose with Material3 in Android. I am not able to align the text next to check box. Please help. Here is the code and an screenshot image of the emulator screen.

)
}
}
}
I have attached a screen shot of the emulator screen to show how the text is aligned.
Question:
- How can I align the text "Check me" along with check box.
- How can I bring it closer to check box.
Please help.
I tried to place text next to checkbox in my android studio material 3 project. The text is not aligned in line with the checkbox.

以下是翻译好的代码部分:
@Composable
fun Test() {
var selected by remember { mutableStateOf(false) }
Row(
modifier = Modifier
.fillMaxWidth()
.padding(10.dp),
horizontalArrangement = Arrangement.SpaceBetween
) {
Row {
Checkbox(checked = selected, onCheckedChange = { selected = it })
Spacer(modifier = Modifier.width(5.dp))
Text(
text = "Check me",
fontWeight = FontWeight.Bold,
fontSize = 18.sp,
color = Color.Black,
modifier = Modifier.align(CenterVertically)
)
}
Text(
text = "Right text",
fontSize = 18.sp,
color = Color.Blue,
modifier = Modifier.align(CenterVertically)
)
}
}
请注意,我已将代码中的HTML实体“"”翻译为正常的双引号(")以便于理解。
英文:
For that you have to align both the text Center Vertically , Below is the full code.
@Composable
fun Test() {
var selected by remember { mutableStateOf(false) }
Row(
modifier = Modifier
.fillMaxWidth()
.padding(10.dp),
horizontalArrangement = Arrangement.SpaceBetween
) {
Row {
Checkbox(checked = selected, onCheckedChange = { selected = it })
Spacer(modifier = Modifier.width(5.dp))
Text(
text = "Check me",
fontWeight = FontWeight.Bold,
fontSize = 18.sp,
color = Color.Black,
modifier = Modifier.align(CenterVertically)
)
}
Text(
text = "Right text",
fontSize = 18.sp,
color = Color.Blue,
modifier = Modifier.align(CenterVertically)
)
}
}

您可以使用此指南进行对齐:https://developer.android.com/jetpack/compose/layouts/alignment-lines
我在测试您的代码时,得到了以下结果:
fun Modifier.firstBaselineToTop(
firstBaselineToTop: Dp
) = layout { measurable, constraints ->
// 测量组件
val placeable = measurable.measure(constraints)
// 检查组件是否具有第一个基线
check(placeable[FirstBaseline] != AlignmentLine.Unspecified)
val firstBaseline = placeable[FirstBaseline]
// 带有填充的组件的高度 - 第一个基线
val placeableY = firstBaselineToTop.roundToPx() - firstBaseline
val height = placeable.height + placeableY
layout(placeable.width, height) {
// 组件的放置位置
placeable.placeRelative(0, placeableY)
}
}
@Composable
fun Test() {
Row(
horizontalArrangement = Arrangement.Start,
modifier = Modifier.padding(0.dp)
) {
Row {
Checkbox(
checked = true,
onCheckedChange = { },
modifier = Modifier.absoluteOffset((-12).dp, 0.dp)
)
Text(
text = "Check me",
Modifier.padding(vertical = 10.dp),
fontWeight = FontWeight.Bold,
fontSize = 18.sp,
textAlign = TextAlign.Left
)
}
TextButton(
onClick = { },
modifier = Modifier.padding(end = 0.dp)
) {
Text(
text = "Right text",
Modifier.firstBaselineToTop(16.dp),
fontWeight = FontWeight.Bold,
fontSize = 18.sp,
textAlign = TextAlign.Right
)
}
}
}
英文:
You can you this guide to align: https://developer.android.com/jetpack/compose/layouts/alignment-lines
I was playing around with your code, and here is what I get:
fun Modifier.firstBaselineToTop(
firstBaselineToTop: Dp
) = layout { measurable, constraints ->
// Measure the composable
val placeable = measurable.measure(constraints)
// Check the composable has a first baseline
check(placeable[FirstBaseline] != AlignmentLine.Unspecified)
val firstBaseline = placeable[FirstBaseline]
// Height of the composable with padding - first baseline
val placeableY = firstBaselineToTop.roundToPx() - firstBaseline
val height = placeable.height + placeableY
layout(placeable.width, height) {
// Where the composable gets placed
placeable.placeRelative(0, placeableY)
}
}
@Composable
fun Test() {
Row(
horizontalArrangement = Arrangement.Start,
modifier = Modifier.padding(0.dp)
) {
Row {
Checkbox(
checked = true,
onCheckedChange = { },
modifier = Modifier.absoluteOffset((-12).dp, 0.dp)
)
Text(
text = "Check me",
Modifier.padding(vertical =10.dp),
fontWeight = FontWeight.Bold,
fontSize = 18.sp,
textAlign = TextAlign.Left
)
}
TextButton(
onClick = { },
modifier = Modifier.padding(end = 0.dp)
) {
Text(
text = "Right text",
Modifier.firstBaselineToTop(16.dp),
fontWeight = FontWeight.Bold,
fontSize = 18.sp,
textAlign = TextAlign.Right
)
}
}
}
