I want make a UI like this picture.
What I want:
Now my result:
My code:
Row(
verticalAlignment = Alignment.CenterVertically
) {
Image(
imageVector = Icons.Rounded.CheckCircle,
contentDescription = null,
modifier = Modifier
.size(16.dp)
.onGloballyPositioned {
topOffset = it.boundsInRoot().bottomCenter
}
)
Spacer(modifier = Modifier.size(8.dp))
Text(
text = "abcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcd",
fontSize = 16.sp,
)
}
Spacer(modifier = Modifier.size(8.dp))
Row(
verticalAlignment = Alignment.CenterVertically
) {
Image(
imageVector = Icons.Rounded.CheckCircle,
contentDescription = null,
modifier = Modifier
.size(16.dp)
.onGloballyPositioned {
bottomOffset = it.boundsInRoot().bottomCenter
}
)
Spacer(modifier = Modifier.size(8.dp))
Text(
text = "abcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcd",
fontSize = 16.sp,
)
}
I want draw a vertical line between the CheckCircle icons.
You can have a fixed height and then draw a line behind. You should also have another icon with white arrow.
An example:
#Composable
fun checkComposable() {
// padding between rows
val padding = 50.dp
Row {
Box(Modifier.height(intrinsicSize = IntrinsicSize.Min)) {
Box(modifier = Modifier
.width(4.dp)
.padding(top = padding / 2, bottom = padding / 2)
.fillMaxHeight()
.background(Color.Black)
.align(Alignment.Center))
Column {
Box(Modifier.height(padding)) {
Image(
imageVector = Icons.Rounded.CheckCircle,
contentDescription = null,
modifier = Modifier
.size(16.dp)
.align(Alignment.Center)
)
}
Box(Modifier.height(padding)) {
Image(
imageVector = Icons.Rounded.CheckCircle,
contentDescription = null,
modifier = Modifier
.size(16.dp)
.align(Alignment.Center)
)
}
}
}
Spacer(modifier = Modifier.width(8.dp))
Column{
Box(Modifier.height(padding)) {
Text(
modifier = Modifier.align(Alignment.CenterStart),
text = "abcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcd",
fontSize = 16.sp,
)
}
Box(Modifier.height(padding)) {
Text(
modifier = Modifier.align(Alignment.CenterStart),
text = "abcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcd",
fontSize = 16.sp,
)
}
}
}
}
A workaround, could be this:
Row {
Vector() // Complete Icon, ticks and line
Column {
Text(...)
Text(...)
}
}

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
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
Me and my team are new to Compose and we're trying to build a TopUp screen for a client. The screen consists of a Column that contains some Padding (in the form of a Composable) for the TopAppBar, two Card composables, a button, then a footer composable which I need to constraint to the bottom of the column, and finally, some padding (again in the form of a composable) to give us some space between the content and the bottom navbar.
Right now we're using a spacer with a fixed dp value but obviously, this won't scale so that it is constrained to the bottom on all devices. What would be the best way to go about achieving such a look?

The easiest way is to use weight modifier:
Spacer(modifier = Modifier.height(130.dp).weight(1f))
Add bottom padding to first Column for give space between content and bottombar. After that give weight to second Column for make footer constraint to the bottom.
For example,
Column(
modifier = Modifier.fillMaxSize().padding(bottom = 15.dp, start = 16.dp, end = 16.dp )
) {
Column(
modifier = Modifier.fillMaxSize().weight(1f).padding(horizontal = 16.dp)
) {
// top bar
// two cards
// button
}
// add footer here
}
I would use a ConstraintLayout and wrap the view you need to always be at the bottom of the screen.
ConstraintLayout {
// Create references for the composables to constrain
val id_of_your_footer = createRefs()
YourFooterComposable(
modifier = Modifier.constrainAs(id_of_your_footer) {
bottom.linkTo(parent.bottom)
}
)
}
As long as the parent is the root view, the Footer will be constrained to stay at the bottom of the screen.
Alternatively, you can use a scaffold that has these constraints set automatically:
Scaffold(topBar={//place a top bar composable here},
content={//all your content composables here},
bottomBar={//your footer composable here})
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() {

super.onCreate(savedInstanceState)

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

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(),
//..
)
//...
}
//...
}
}
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,
)
}
}
