How do I create a rounded checkbox in Jetpackcompose like this. I tried using a Shape composable on it but it doesn't work.
I was looking on how to do the same thing you were asking, your question helped me on my journey so it is only fair I share. Add some animations and you are set my friend.
Make a round looking icon by using a box and an icon
Box(
modifier = Modifier
.clip(CircleShape)
.size(40.dp)
.background(Color.Black)
.padding(3.dp)
.clip(CircleShape)
.background(Color.White),
contentAlignment = Alignment.Center
) {
Icon(imageVector = Icons.Default.Check, contentDescription = "")
}
2.Place the newly made rounded icon and some text next to each other by using a Row
Row(
verticalAlignment = Alignment.CenterVertically,
){
Box(
modifier = Modifier
.clip(CircleShape)
.size(40.dp)
.background(Color.Black)
.padding(3.dp)
.clip(CircleShape)
.background(Color.White),
contentAlignment = Alignment.Center
) {
Icon(imageVector = Icons.Default.Check, contentDescription = "")
}
Text(
text = checkedText.value,
color = color.value,
fontSize = 20.sp,
fontWeight = FontWeight.Medium,
modifier = Modifier.padding(start = 5.dp)
)
}
3.Replace whatever you want with variables so you can customize
it
#Composable
fun RoundedCheckView(
) {
val isChecked = remember { mutableStateOf(false) }
val checkedText = remember { mutableStateOf("unChecked") }
val circleSize = remember { mutableStateOf(20.dp) }
val circleThickness = remember { mutableStateOf(2.dp) }
val color = remember { mutableStateOf(Color.Gray) }
Row(
verticalAlignment = Alignment.CenterVertically,
{
Box(
modifier = Modifier
.clip(CircleShape)
.size(circleSize.value)
.background(color.value)
.padding(circleThickness.value)
.clip(CircleShape)
.background(Color.White) ,
contentAlignment = Alignment.Center
) {
Icon(imageVector = Icons.Default.Check, contentDescription = "")
}
Text(
text = checkedText.value,
color = color.value,
fontSize = 20.sp,
fontWeight = FontWeight.Medium,
modifier = Modifier.padding(start = 5.dp)
)
}
}
4.Finally add Modifier.toggleable to the row, basically making it a clickable item that toggles (between true and false) a variable in this case isChecked. Then just customize the variables according to what you need
#Composable
fun RoundedCheckView()
{
val isChecked = remember { mutableStateOf(false) }
val checkedText = remember { mutableStateOf("unChecked") }
val circleSize = remember { mutableStateOf(20.dp) }
val circleThickness = remember { mutableStateOf(2.dp) }
val color = remember { mutableStateOf(Color.Gray) }
Row(
verticalAlignment = Alignment.CenterVertically,
modifier = Modifier
.toggleable(value = isChecked.value,role = Role.Checkbox) {
isChecked.value = it
if (isChecked.value) {
checkedText.value = "Checked"
circleSize.value = 40.dp
circleThickness.value = 3.dp
color.value = Color.Black
} else {
checkedText.value = "unChecked"
circleSize.value = 20.dp
circleThickness.value = 2.dp
color.value = Color.Gray
}
}) {
Box(
modifier = Modifier
.clip(CircleShape)
.size(circleSize.value)
.background(color.value)
.padding(circleThickness.value)
.clip(CircleShape)
.background(Color.White) ,
contentAlignment = Alignment.Center
) {
if(isChecked.value){
Icon(imageVector = Icons.Default.Check, contentDescription = "")
}
}
Text(
text = checkedText.value,
color = color.value,
fontSize = 20.sp,
fontWeight = FontWeight.Medium,
modifier = Modifier.padding(start = 5.dp)
)
}
}
This is how we can make a custom check box in jetpack compose
val isCheck = remember { mutableStateOf(false) }
Row {
Card(
modifier = Modifier.background(Color.White),
elevation = 0.dp,
shape = RoundedCornerShape(6.dp),
border = BorderStroke(1.5.dp, color = titleColor)
) {
Box(
modifier = Modifier
.size(25.dp)
.background(if (isCheck.value) titleColor else Color.White)
.clickable {
isCheck.value = !isCheck.value
},
contentAlignment = Center
) {
if(isCheck.value)
Icon(Icons.Default.Check, contentDescription = "", tint = Color.White)
}
}
Text(
modifier = Modifier
.align(CenterVertically)
.padding(start = 10.dp),
text = "I agree with the terms & condition",
)
}
You can try to make it use Box with modifier content alignment center. and put an icon on there.
#Preview
#Composable
fun Check() {
Box(
modifier = Modifier
.clip(CircleShape)
.size(50.dp)
.background(Color.Red)
.padding(5.dp)
.clip(CircleShape)
.background(Color.Blue),
contentAlignment = Alignment.Center
) {
Icon(imageVector = Icons.Default.Check, contentDescription = "")
}
}
We can use animations to make it behave similar to the default Checkbox. Using Modifier.toggleable on the top-level Row, the entire thing is clickable, including the label. This also creates the proper semantics for screen reader users. You can change the shape of the card to get a circular checkbox.
#Composable
fun PrimaryCheckbox(
label: String,
modifier: Modifier = Modifier,
size: Float = 24f,
checkedColor: Color = DarkGray,
uncheckedColor: Color = White,
checkmarkColor: Color = White,
onValueChange: () -> Unit
) {
var isChecked by remember { mutableStateOf(false) }
val checkboxColor: Color by animateColorAsState(if (isChecked) checkedColor else uncheckedColor)
val density = LocalDensity.current
val duration = 200
Row(
modifier = modifier
.toggleable(
value = isChecked,
role = Role.Checkbox,
onValueChange = {
isChecked = !isChecked
onValueChange.invoke()
}
)
) {
Card(
elevation = 0.dp,
shape = RoundedCornerShape(4.dp),
border = BorderStroke(1.5.dp, color = checkedColor),
) {
Box(
modifier = Modifier
.size(size.dp)
.background(checkboxColor),
contentAlignment = Alignment.Center
) {
androidx.compose.animation.AnimatedVisibility(
visible = isChecked,
enter = slideInHorizontally(
animationSpec = tween(duration)
) {
with(density) { (size * -0.5).dp.roundToPx() }
} + expandHorizontally(
expandFrom = Alignment.Start,
animationSpec = tween(duration)
),
exit = fadeOut()
) {
Icon(
Icons.Default.Check,
contentDescription = null,
tint = checkmarkColor
)
}
}
}
Text(
modifier = Modifier
.align(Alignment.CenterVertically)
.padding(start = 8.dp),
text = label,
)
}
}

And in manifest I have set up as: android:windowSoftInputMode="adjustResize"
in my activity.
I would like to see the screen moving up with keyboard bellow, without altering the weights. For example when I click on barcode:
Problem is imePadding() remove it and see result
and try use adjustPan in manifest
Based on what was answered in this question (Open ModalSheetLayout on TextField focus instead of Keyboard) and the exchange of comments I did with #Abhimanyu, I was able to get the ModalBottomSheetLayout to appear when I click on one of the TextFields, however I encountered two more problems. I can't center what's in the content, nor can I center the content that's inside the sheet content. Can anyone help me understand why?
Here is a print of what is happening and my code:

I solved this issue by putting all the ModalBottomSheet content inside a Box with Modifier.fillMaxSize() and the contentAlignment = Alignment.Center. See my code below:
ModalBottomSheetLayout(
sheetState = modalBottomSheetState,
sheetShape = RoundedCornerShape(topStart = Dimen13, topEnd = Dimen13),
sheetContent = {
JobDetailsModalBottomSheet(modalBottomSheetType, jobClicked) {
modalBottomSheetType = JobOpeningsScreenModalBottomSheetType.NONE
toggleModalBottomSheetState(
coroutineScope = coroutineScope,
modalBottomSheetState = modalBottomSheetState,
)
}
}) {
Box(contentAlignment = Alignment.Center, modifier = Modifier.fillMaxSize()) {
// any content
}
}
I'm not really sure why this doesn't work without Box, but after a few tries, this was the solution I found and it worked.
I am new in jetpack compose, and I am try to learn it, so I have simple onboarding screen in jetpack compose, when I update project to jetpack compose 1.1.1 , "Next" button not working for onboarding screen to scroll horizontally. it was working when I use jetpack compose 1.0.0 version, I do not know what change in new version, any idea?

It looks like you expect these lines to scroll the pager every time you change the value of currentPage:
LaunchedEffect(scaffoldState.snackbarHostState) {
pagerState.animateScrollToPage(
page = currentPage.value
)
}
But scaffoldState.snackbarHostState in this scope is a static value, which means LaunchedEffect is not gonna be relaunched.
One option is to pass currentPage instead, but also, as your currentPage is backed by flow, it's cleaner to collect it:
LaunchedEffect(Unit) {
onBoardViewModel.currentPage
.collect {
pagerState.animateScrollToPage(
page = currentPage.value
)
}
}
p.s.
Also, when you need to make a text button, instead of adding clickable to the Text you can use TextButton:
TextButton(
onClick = {
}
) {
Text(/*...*/)
}
I have the following page on which I'm trying to display a list of saved cards with the ability to add a new one. The last item in the column is an expandable one so that when clicked, the user can see a form for filling out card info in order to add a new card. This was working just fine yesterday, but I can't figure out why it's not working today.
The actual CardItem elements receive clicks just fine but the custom expandable one does not and neither does the ShadowWrapper parent nor the RaisedCard one.

I wasn't able to reproduce your issue, probably because other parts of your application are triggering additional recompositions. However the cause is most likely that you forget to remember your MutableInteractionSources.
Like this:
otherModifiers.clickable(
indication = null,
interactionSource = remember { MutableInteractionSource() }
) { // this does not register at all, tried with Log.d
selectedCardIndex = cardList.size
}
If you do not wrap MutableInteractionSource in a remember, a new instance is created on every recomposition, so state like a previous touch events is lost
I got into Jetpack compose and I am having a hard time finding examples of a normal screen. Everyone just uses scaffold and calls it a day. Using fillMaxSize is supposed to do exactly this, can someone explain how composable inherit their size? The topmost composable specifically (root composable)?
#Composable
fun MainContent() {
Surface(modifier = Modifier.fillMaxSize()) {
Column() {
SearchBox()
CurrentWeather()
WindAndHumidityBox()
}
}
}
class MainActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
ComposeweathertestTheme {
// A surface container using the 'background' color from the theme
Surface(
color = MaterialTheme.colors.background,
modifier = Modifier.fillMaxSize()
) {
MainContent()
}
}
}
}
}
Also the PURPLE portion is using this code.
Surface(
modifier = Modifier
.padding(40.dp).wrapContentHeight(), elevation = 3.dp, shape = RoundedCornerShape(8.dp),
color = MaterialTheme.colors.primarySurface
) {
In XML we could use wrap content and apply padding to it, this doesn't seem to be the case with compose? I am trying to do something like this
EDIT: Whole compose file
#Composable
private fun Content() {
Column(modifier = Modifier.fillMaxSize()) {
SearchBox()
CurrentWeather()
WindAndHumidityBox()
}
}
#Composable
fun WindAndHumidityBox() {
Surface(
modifier = Modifier
.padding(40.dp)
.wrapContentHeight(), elevation = 3.dp, shape = RoundedCornerShape(8.dp),
color = MaterialTheme.colors.primarySurface
) {
Row {
Row(modifier = Modifier.align(Alignment.CenterVertically)) {
Image(
painter = painterResource(id = R.drawable.day_clear),
contentDescription = "humidity"
)
Text(
text = "Precipitation \n 10%", fontWeight = FontWeight.Bold, fontSize = 20.sp,
modifier = Modifier.align(Alignment.CenterVertically)
)
}
Row(modifier = Modifier.align(Alignment.CenterVertically)) {
Image(
painter = painterResource(id = R.drawable.day_clear),
contentDescription = "humidity"
)
Text(
text = "Precipitation \n 10%", fontWeight = FontWeight.Bold, fontSize = 20.sp,
modifier = Modifier.align(Alignment.CenterVertically)
)
}
}
}
}
#Composable
private fun CurrentWeather() {
Box(modifier = Modifier.fillMaxWidth()) {
Column(Modifier.align(Alignment.Center)) {
Column(modifier = Modifier.padding(bottom = 20.dp)) { // location and time/date
Row(modifier = Modifier.align(Alignment.CenterHorizontally)) {
Icon(
painter = painterResource(id = R.drawable.ic_location),
contentDescription = "location"
)
Text(
text = "London", fontWeight = FontWeight.Bold, fontSize = 20.sp,
modifier = Modifier.align(Alignment.CenterVertically)
)
}
Text(text = "Thu 4 December 8:41 am")
}
Row(Modifier.align(Alignment.CenterHorizontally)) {
Image(
painterResource(id = R.drawable.day_clear),
modifier = Modifier.align(alignment = Alignment.CenterVertically),
contentDescription = "current weather image displaying the current weather"

.padding(top = 20.dp),

You are using too many parent containers.
Just use:
Surface(
color = MaterialTheme.colors.background,
modifier = Modifier.fillMaxSize()
){
Column(){
WindAndHumidityBox()
}
}
Then you can achieve the PURPLE portion in many ways.
In particular check the Intrinsic measurements.
For example:
Surface(
modifier = Modifier
.padding(horizontal = 16.dp)
.fillMaxWidth(),
elevation = 3.dp,
shape = RoundedCornerShape(8.dp),
color = MaterialTheme.colors.primarySurface
) {
Row(
Modifier.padding(40.dp), //Padding inside the Row
horizontalArrangement = Arrangement.Center
) {
Row(modifier = Modifier
.align(Alignment.CenterVertically)
.height(IntrinsicSize.Min) //Intrinsic measurements to center the icon vertically
) {
Image(
modifier = Modifier.fillMaxHeight(),
//..
)
//...
}
//...
}
}
