Why BasicTextField (in compose) doesn't work well?

Why BasicTextField (in compose) doesn't work well? - android

I'm trying to use BasicTextField with TextAlignment.End for RTL. it's my code:
val textState = remember { mutableStateOf(TextFieldValue("")) }
val shape = RoundedCornerShape(CornerSize(4.dp))
BasicTextField(
value = textState.value,
onValueChange = { newText -> textState.value = newText },
textStyle = LocalTextStyle.current.copy(
color = ColorPrimaryDarkText,
fontWeight = FontWeight.Medium,
textAlign = TextAlign.End,
fontSize = 14.sp,
),
maxLines = 1,
singleLine = true,
modifier = Modifier
.fillMaxWidth()
.padding(32.dp, 0.dp)
.clip(shape)
.background(color = Color.White),
keyboardOptions = KeyboardOptions(
keyboardType = KeyboardType.Text,
imeAction = ImeAction.Done
),
decorationBox = { innerTextField ->
Row(
modifier = Modifier
.fillMaxWidth()
.background(Color.White, shape)
.padding(8.dp),
) {
if (textState.value.text.isEmpty()) {
Text(
text = "hint",
textAlign = TextAlign.End,
fontWeight = FontWeight.Medium,
modifier = Modifier.fillMaxWidth(),
fontSize = 14.sp,
)
} else {
innerTextField()
}
}
}
)
it's OK when it's empty but it's not working well when you try to type anything (it's starting to type from center):

Remove the textAlign = TextAlign.End and use something like:
CompositionLocalProvider(LocalLayoutDirection provides LayoutDirection.Rtl ) {
BasicTextField( /* your code */)
}
Otherwise if you want to use your code add horizontalArrangement = Arrangement.End in Row in the decorationBox parameter:
decorationBox = { innerTextField ->
Row(
modifier = Modifier
.fillMaxWidth()
.background(Color.White, shape)
.padding(8.dp),
horizontalArrangement = Arrangement.End){
//your code
}

How to dismiss a composable dialog?

I am a new in jetpack compose and I really wanted to know how I can dismiss a composable dialog. Is there any function like dismiss() for dialog in jetpack compose?
By using below code, I cannot dismiss the dialog either touching outside or pressing back button. The dialog just still is visible on the top of view hierarchy.
`
#Composable
fun InfoDialog() {
val shouldDismiss = remember {
mutableStateOf(false)
}
Dialog(onDismissRequest = {
shouldDismiss.value = false
}, properties = DialogProperties(
dismissOnBackPress = true,
dismissOnClickOutside = true
)) {
Card(
shape = RoundedCornerShape(8.dp),
modifier = Modifier.padding(16.dp,8.dp,16.dp,8.dp),
elevation = 8.dp
) {
Column(
Modifier.background(c282534)) {
Column(modifier = Modifier.padding(16.dp)) {
Text(
text = "Notice",
textAlign = TextAlign.Center,
modifier = Modifier
.padding(top = 8.dp)
.fillMaxWidth(),
style = TextStyle(fontWeight = FontWeight.Bold, color = Color.White, fontSize = 24.sp),
maxLines = 2,
overflow = TextOverflow.Ellipsis
)
Text(
text = "Allow Permission to send you notifications when important update added.",
textAlign = TextAlign.Center,
modifier = Modifier
.padding(top = 8.dp, start = 24.dp, end = 24.dp)
.fillMaxWidth(),
style = TextStyle(color = Color.White, fontSize = 16.sp)
)
}
Row(
Modifier
.fillMaxWidth()
.padding(top = 8.dp),
horizontalArrangement = Arrangement.SpaceAround) {
TextButton(onClick = {
shouldDismiss.value = true
}, modifier = Modifier.weight(1f)) {
Text(
"Close",
fontWeight = FontWeight.Normal,
color = Color.White,
modifier = Modifier.padding(top = 8.dp, bottom = 8.dp)
)
}
TextButton(
onClick = {
shouldDismiss.value = true
},
modifier = Modifier.weight(1f)
) {
Text(
"Allow",
fontWeight = FontWeight.ExtraBold,
color = Color.White,
modifier = Modifier.padding(top = 8.dp, bottom = 8.dp)
)
}
}
}
}
}
}
`

First, you should setup onDismissRequest, I guess in your case it will be shouldDismiss.value = true. Then you should hide Dialog based on shouldDismiss value. In order to hide you should just stop invoking Dialog {... function in your code based on condition. E.g. by adding fast return if (shouldDismiss.value) return. Finally it will look like this:
#Composable
fun InfoDialog() {
val shouldDismiss = remember {
mutableStateOf(false)
}
if (shouldDismiss.value) return
Dialog(onDismissRequest = {
shouldDismiss.value = true
}, properties = DialogProperties(
dismissOnBackPress = true,
dismissOnClickOutside = true
)) {
Card(
shape = RoundedCornerShape(8.dp),
modifier = Modifier.padding(16.dp,8.dp,16.dp,8.dp),
elevation = 8.dp
) {
Column(
Modifier.background(c282534)) {
Column(modifier = Modifier.padding(16.dp)) {
Text(
text = "Notice",
textAlign = TextAlign.Center,
modifier = Modifier
.padding(top = 8.dp)
.fillMaxWidth(),
style = TextStyle(fontWeight = FontWeight.Bold, color = Color.White, fontSize = 24.sp),
maxLines = 2,
overflow = TextOverflow.Ellipsis
)
Text(
text = "Allow Permission to send you notifications when important update added.",
textAlign = TextAlign.Center,
modifier = Modifier
.padding(top = 8.dp, start = 24.dp, end = 24.dp)
.fillMaxWidth(),
style = TextStyle(color = Color.White, fontSize = 16.sp)
)
}
Row(
Modifier
.fillMaxWidth()
.padding(top = 8.dp),
horizontalArrangement = Arrangement.SpaceAround) {
TextButton(onClick = {
shouldDismiss.value = true
}, modifier = Modifier.weight(1f)) {
Text(
"Close",
fontWeight = FontWeight.Normal,
color = Color.White,
modifier = Modifier.padding(top = 8.dp, bottom = 8.dp)
)
}
TextButton(
onClick = {
shouldDismiss.value = true
},
modifier = Modifier.weight(1f)
) {
Text(
"Allow",
fontWeight = FontWeight.ExtraBold,
color = Color.White,
modifier = Modifier.padding(top = 8.dp, bottom = 8.dp)
)
}
}
}
}
}
}

The dialog is visible as long as it is part of the composition hierarchy.
You should use something like:
val shouldShowDialog = remember { mutableStateOf(true) }
if (shouldShowDialog.value) {
Dialog(onDismissRequest = { shouldShowDialog.value = false }) {
Button(onClick = {shouldShowDialog.value = false}){
Text("Close")
}
}
}
Setting shouldShowDialog to false dismisses the Dialog. And to show just set shouldShowDialog to true. Something like:
Button(onClick = {shouldShowDialog.value = true}){
Text("Open")
}

Clickable modifier on Row not receiving events

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

Constraining a Composable to the bottom of a Column

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})

Jetpack Compose Textfield Alignment

I'm new to jetpack compose. I want to start typing from TextField's centervertically-start
position but I can't put "Example" to center
vertically-start position.
Row(
modifier = Modifier
.fillMaxWidth()
.height(50.dp)
.shadow(5.dp)
.background(Color.Yellow),
) {
BasicTextField(
value = text,
onValueChange = {onvalueChange(it)},
modifier = Modifier.weight(10f).background(Color.Blue).fillMaxSize(),
singleLine = true,
textStyle = LocalTextStyle.current.copy(
textAlign = TextAlign.Center
)
)
Image(painter = painterResource(id = R.drawable.ic_baseline_search_24),
contentDescription = "Search",
modifier = Modifier.weight(2f).fillMaxSize()
)
This is my code
And this is what I want to do.

Row has a verticalAlignment for this. Also, if you want your TextField left align like the picture, remove the textAlign (or change it but it default to start)
Row(
modifier = Modifier
.fillMaxWidth()
.height(50.dp)
.shadow(5.dp)
.background(Color.Yellow),
verticalAlignment = Alignment.CenterVertically,
) {
BasicTextField(
value = text,
onValueChange = {onvalueChange(it)},
modifier = Modifier.weight(10f).background(Color.Blue).fillMaxSize(),
singleLine = true,
)
Image(painter = painterResource(id = R.drawable.ic_baseline_search_24),
contentDescription = "Search",
modifier = Modifier.weight(2f).fillMaxSize()
)
}

Use background box to control, please try:
Row(
modifier = Modifier
.fillMaxWidth()
.height(50.dp)
.shadow(5.dp)
.background(Color.Yellow),
) {
Box(Modifier.weight(10f).background(Color.Blue).fillMaxSize(),contentAlignment = CenterStart){
BasicTextField(
value = text,
onValueChange = { onvalueChange(it) },
modifier = Modifier.wrapContentHeight(
Alignment.CenterVertically),
singleLine = true,
textStyle = LocalTextStyle.current.copy(
textAlign = TextAlign.Start
)
)
}
Image(
Icons.Filled.Search,
contentDescription = "Search",
modifier = Modifier.weight(2f).fillMaxSize()
)
}

How clear focus for BasicTextField in Jetpack Compose?

I have a Jetpack Compose (Beta04) BasicTextField (with decorationBox). How can I clear the focus?
I have tried with focusRequester but this doesn't works:
val focusRequester = remember { FocusRequester() }
// ...
BasicTextField(modifier = Modifier.focusRequester(focusRequester), /* ... */)
// ...
placesFocusRequester.freeFocus()

To clear focus from the currently focused component you can use the FocusManager.clearFocus method:
val focusRequester = remember { FocusRequester() }
val focusManager = LocalFocusManager.current
var value by rememberSaveable { mutableStateOf("initial value") }
BasicTextField(
value = value,
onValueChange = { value = it },
decorationBox = { innerTextField ->
Row(
Modifier
.background(Color.LightGray, RoundedCornerShape(percent = 30))
.padding(16.dp)
.focusRequester(focusRequester)
) {
//...
innerTextField()
}
}
)
Button(onClick = { focusManager.clearFocus() }) {
Text("Clear focus")
}
