Show custom alert dialog in Jetpack Compose - android

I am searching how create custom dialog in Jetpack Compose. In XML or Material Design we can create easily custom Dialog in which we can take user input, radio button etc. but i am not finding such thing in Jetpack Compose.

Starting from M3 1.1.0-alpha04 there is an AlertDialog composable function with a slot for content.
val openDialog = remember { mutableStateOf(true) }
if (openDialog.value) {
androidx.compose.material3.AlertDialog(
onDismissRequest = {
// Dismiss the dialog when the user clicks outside the dialog or on the back
// button. If you want to disable that functionality, simply use an empty
// onDismissRequest.
openDialog.value = false
}
) {
Surface(
modifier = Modifier
.wrapContentWidth()
.wrapContentHeight(),
shape = MaterialTheme.shapes.large
) {
Column(modifier = Modifier.padding(16.dp)) {
//... AlertDialog content
}
}
}
}
Before M3 1.1.0-alpha04 or with M2, you can use the standard AlertDialog.
The text,title and buttons parameters support #Composable functions and in this way you can customize the dialog as you prefer.
For example:
val openDialog = remember { mutableStateOf(true) }
var text by remember { mutableStateOf("") }
if (openDialog.value) {
AlertDialog(
onDismissRequest = {
openDialog.value = false
},
title = {
Text(text = "Title")
},
text = {
Column() {
TextField(
value = text,
onValueChange = { text = it }
)
Text("Custom Text")
Checkbox(checked = false, onCheckedChange = {})
}
},
buttons = {
Row(
modifier = Modifier.padding(all = 8.dp),
horizontalArrangement = Arrangement.Center
) {
Button(
modifier = Modifier.fillMaxWidth(),
onClick = { openDialog.value = false }
) {
Text("Dismiss")
}
}
}
)
}

This example demonstrates how to make custom dialog in android jet compose.

Also adding a lambda to return value from dialog back to any other composable is possible with
#Composable
private fun CustomDialogWithResultExample(
onDismiss: () -> Unit,
onNegativeClick: () -> Unit,
onPositiveClick: (Color) -> Unit
) {
var red by remember { mutableStateOf(0f) }
var green by remember { mutableStateOf(0f) }
var blue by remember { mutableStateOf(0f) }
val color = Color(
red = red.toInt(),
green = green.toInt(),
blue = blue.toInt(),
alpha = 255
)
Dialog(onDismissRequest = onDismiss) {
Card(
elevation = 8.dp,
shape = RoundedCornerShape(12.dp)
) {
Column(modifier = Modifier.padding(8.dp)) {
Text(
text = "Select Color",
fontWeight = FontWeight.Bold,
fontSize = 20.sp,
modifier = Modifier.padding(8.dp)
)
Spacer(modifier = Modifier.height(8.dp))
// Color Selection
Row(
verticalAlignment = Alignment.CenterVertically,
horizontalArrangement = Arrangement.Center
) {
Column {
Text(text = "Red ${red.toInt()}")
Slider(
value = red,
onValueChange = { red = it },
valueRange = 0f..255f,
onValueChangeFinished = {}
)
Spacer(modifier = Modifier.height(8.dp))
Text(text = "Green ${green.toInt()}")
Slider(
value = green,
onValueChange = { green = it },
valueRange = 0f..255f,
onValueChangeFinished = {}
)
Spacer(modifier = Modifier.height(8.dp))
Text(text = "Blue ${blue.toInt()}")
Slider(
value = blue,
onValueChange = { blue = it },
valueRange = 0f..255f,
onValueChangeFinished = {}
)
Spacer(modifier = Modifier.height(8.dp))
Surface(
border = BorderStroke(1.dp, Color.DarkGray),
color = color,
modifier = Modifier
.fillMaxWidth()
.height(40.dp)
) {}
}
}
// Buttons
Row(
horizontalArrangement = Arrangement.End,
modifier = Modifier.fillMaxWidth()
) {
TextButton(onClick = onNegativeClick) {
Text(text = "CANCEL")
}
Spacer(modifier = Modifier.width(4.dp))
TextButton(onClick = {
onPositiveClick(color)
}) {
Text(text = "OK")
}
}
}
}
}
}
And show it with
var showCustomDialogWithResult by remember { mutableStateOf(false) }
if (showCustomDialogWithResult) {
CustomDialogWithResultExample(
onDismiss = {
showCustomDialogWithResult = !showCustomDialogWithResult
Toast.makeText(context, "Dialog dismissed!", Toast.LENGTH_SHORT)
.show()
},
onNegativeClick = {
showCustomDialogWithResult = !showCustomDialogWithResult
Toast.makeText(context, "Negative Button Clicked!", Toast.LENGTH_SHORT)
.show()
},
onPositiveClick = { color ->
showCustomDialogWithResult = !showCustomDialogWithResult
Toast.makeText(context, "Selected color: $color", Toast.LENGTH_SHORT)
.show()
}
)
}
And result is

I had to achieve something like this:
Putting image in "title" slot and text in "text" slot of compose AlertDialog, ended with this:
Because "title" and "text" are wrapped with AlertDialogBaselineLayout that is adding padding, and I did not have a clue how to change it.
However, "buttons" slot was not wrapped, and my solution was like in following code ("title" and "text" slot must be set to null and all of dialog content goes into "buttons" slot):
#Composable
fun AppDialog(
modifier: Modifier = Modifier,
dialogState: Boolean = false,
onDialogPositiveButtonClicked: (() -> Unit)? = null,
onDialogStateChange: ((Boolean) -> Unit)? = null,
onDismissRequest: (() -> Unit)? = null,
) {
val textPaddingAll = 24.dp
val buttonPaddingAll = 8.dp
val dialogShape = RoundedCornerShape(16.dp)
if (dialogState) {
AlertDialog(
onDismissRequest = {
onDialogStateChange?.invoke(false)
onDismissRequest?.invoke()
},
title = null,
text = null,
buttons = {
Column{
Image(
painter = painterResource(R.drawable.dialog_top_image),
contentDescription = "",
contentScale = ContentScale.FillWidth,
modifier = Modifier.fillMaxWidth()
)
Row(Modifier.padding(all = textPaddingAll)){
TextWithHTMLSupport(
text = stringResource(R.string.gdprText)
)
}
Divider(color = MaterialTheme.colors.onSurface, thickness = 1.dp)
Row(
modifier = Modifier.padding(all = buttonPaddingAll),
horizontalArrangement = Arrangement.Center
) {
TextButton(
modifier = Modifier.fillMaxWidth(),
onClick = {
onDialogStateChange?.invoke(false)
onDialogPositiveButtonClicked?.invoke()
}
) {
Text(text = stringResource(R.string.dialog_ok), color = MaterialTheme.colors.onSurface)
}
}
}
},
properties = DialogProperties(dismissOnBackPress = true, dismissOnClickOutside = false),
modifier = modifier,
shape = dialogShape
)
}
}

If the content of your custom alert dialog need to scroll (eg: landscape mode or the content get longer). You can do like
#Composable
fun CustomDialogScrollable(
onConfirmClicked: () -> Unit,
onDismiss: () -> Unit,
) {
Dialog(
onDismissRequest = onDismiss,
) {
Surface(
shape = MaterialTheme.shapes.medium,
color = MaterialTheme.colors.surface,
) {
Column(modifier = Modifier.padding(16.dp)) {
// TITLE
Text(text = "Title", style = MaterialTheme.typography.subtitle1)
Column(
modifier = Modifier
.fillMaxWidth()
.verticalScroll(rememberScrollState())
.weight(weight = 1f, fill = false)
.padding(vertical = 16.dp)
) {
Text(
text = "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s",
style = MaterialTheme.typography.body2
)
OutlinedTextField(value = "", onValueChange = {
}, Modifier.padding(top = 8.dp), label = { Text(text = "Email") })
// other content can go here
}
// BUTTONS
Row(modifier = Modifier.fillMaxWidth(), horizontalArrangement = Arrangement.End) {
TextButton(onClick = onDismiss) {
Text(text = "Cancel")
}
TextButton(onClick = onConfirmClicked) {
Text(text = "OK")
}
}
}
}
}
}
Using
val openDialog = remember { mutableStateOf(true) }
if (openDialog.value) {
CustomDialog({
// confirm clicked
}, {
openDialog.value = false
})
}

Custom dialog with Image
To create a custom dialog like this.
First, create Dialog composable and set dismissRequest and dialog properties.
Inside the dialog create your own view.
finally, set up the dismiss dialog on the desired button.
#Composable
fun CustomAlertDialog(onDismiss: () -> Unit, onExit: () -> Unit) {
Dialog(onDismissRequest = { onDismiss() }, properties = DialogProperties(
dismissOnBackPress = false,dismissOnClickOutside = false
)) {
Card(
//shape = MaterialTheme.shapes.medium,
shape = RoundedCornerShape(10.dp),
// modifier = modifier.size(280.dp, 240.dp)
modifier = Modifier
.fillMaxWidth()
.padding(8.dp),
elevation = 8.dp
) {
Column(
Modifier
.fillMaxWidth()
.background(Color.White)
) {
Row(
modifier = Modifier
.fillMaxWidth()
.height(100.dp)
.background(Color.Red.copy(alpha = 0.8F)),
verticalAlignment = Alignment.CenterVertically,
horizontalArrangement = Arrangement.Center,
) {
Image(
painter = painterResource(id = R.drawable.background_image),
contentDescription = "Exit app",
modifier = Modifier.fillMaxSize(),
contentScale = ContentScale.FillWidth
)
}
Text(
text = "Lorem Ipsum is simply dummy text",
modifier = Modifier.padding(8.dp), fontSize = 20.sp
)
Text(
text = "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard",
modifier = Modifier.padding(8.dp)
)
Row(Modifier.padding(top = 10.dp)) {
OutlinedButton(
onClick = { onDismiss() },
Modifier
.fillMaxWidth()
.padding(8.dp)
.weight(1F)
) {
Text(text = "Cancel")
}
Button(
onClick = { onExit() },
Modifier
.fillMaxWidth()
.padding(8.dp)
.weight(1F)
) {
Text(text = "Exit")
}
}
}
}
}
}
Now we have created the Custom dialog, to show the dialog on button click, you need to create a mutableStateOf() variable to maintain the dialog show and dismiss state.
Also, create conditions like if the variable is true call the dialog, otherwise don’t call the dialog function.
#Composable
fun Content() {
val context = LocalContext.current
var showCustomDialog by remember {
mutableStateOf(false)
}
Column(
Modifier.fillMaxSize(),
Arrangement.Center,
horizontalAlignment = Alignment.CenterHorizontally
) {
Button(onClick = { showCustomDialog = !showCustomDialog }, Modifier.wrapContentSize()) {
Text(text = "Show Alert Dialog")
}
}
if (showCustomDialog) {
CustomAlertDialog({
showCustomDialog = !showCustomDialog
}, {
val activity = (context as? Activity)
activity?.finish()
})
}
}
when clicking on the dismiss button on the dialog, need to update a variable to false to hide the dialog.
The final output of the code is below,
Alert dialog with Input field
As mentioned above, we need to create the dialog with a Dialog() composable function. But for the input field, we need to create a mutableStateOf() variable to hold the values of the input field.
#Composable
fun InputDialogView(onDismiss:() -> Unit) {
val context = LocalContext.current
var searchedFood by remember {
mutableStateOf("")
}
Dialog(onDismissRequest = { onDismiss() }) {
Card(
//shape = MaterialTheme.shapes.medium,
shape = RoundedCornerShape(10.dp),
// modifier = modifier.size(280.dp, 240.dp)
modifier = Modifier.padding(8.dp),
elevation = 8.dp
) {
Column(
Modifier
.background(Color.White)
) {
Text(
text = "Search your favorite food",
modifier = Modifier.padding(8.dp),
fontSize = 20.sp
)
OutlinedTextField(
value = searchedFood,
onValueChange = { searchedFood = it }, modifier = Modifier.padding(8.dp),
label = { Text("Favorite Food") }
)
Row {
OutlinedButton(
onClick = { onDismiss() },
Modifier
.fillMaxWidth()
.padding(8.dp)
.weight(1F)
) {
Text(text = "Cancel")
}
Button(
onClick = {
Toast.makeText(context, searchedFood, Toast.LENGTH_SHORT).show()
onDismiss() },
Modifier
.fillMaxWidth()
.padding(8.dp)
.weight(1F)
) {
Text(text = "Search")
}
}
}
}
}
}
To display the dialog you need to follow the same way above. by creating the mutableStateOf() variable and making it true or false.
The output of the above code is,
Loading Dialog
For the loading dialog, we need to use CircularProgressIndicator() composable function for loading animation. Apart from that everything is the same as other custom dialogs.
#Composable
fun LoadingView(onDismiss:() -> Unit) {
Dialog(onDismissRequest = { onDismiss() }) {
Card(
shape = RoundedCornerShape(8.dp),
modifier = Modifier,
elevation = 8.dp
) {
Column(
Modifier
.background(Color.White)
.padding(12.dp)
) {
Text(
text = "Loading.. Please wait..",
Modifier
.padding(8.dp), textAlign = TextAlign.Center
)
CircularProgressIndicator(
strokeWidth = 4.dp,
modifier = Modifier
.align(Alignment.CenterHorizontally)
.padding(8.dp)
)
}
}
}
}
The output of the about loading dialog code,

It's easy to create a custom dialog in Jetpack Compose.
Here is a dialog box that asks to enalbe 2 Step verification. I have also added click events.

unable botton when slider moves jetpack compose

I have a simple slider that I need to disable the button at star and when user moves the slider it should be enabled, i can disable it at first but i cant to enable it back, for some reason it doesnt take the new variable value this is my code.
My thoughts its because the var is declared at first and the slider value is capsuled somehow?
but if that is the case how do i pass the value to the component?
#OptIn(ExperimentalComposeUiApi::class)

var sliderPosition by remember { mutableStateOf(5f) }
var enable by remember { mutableStateOf(false) }
val recommend = sliderPosition.toInt()

var comment by remember { mutableStateOf("") }
val keyboardController = LocalSoftwareKeyboardController.current
TextField(

if (enable){
Button(
modifier = Modifier
.fillMaxWidth()
.padding(10.dp),
onClick = {
onConfirm(recommend,comment)
openDialog.value = !openDialog.value
}
) {
Text(
text = "¡Contesta y gana +20 puntos!",
style = MaterialTheme.typography.subtitle2,
fontWeight = FontWeight.Bold,
modifier = Modifier.padding(3.dp))
}
}else{
Button(
modifier = Modifier
.fillMaxWidth()
.padding(10.dp),
onClick = {
}
) {
Text(
text = "¡Contesta y gana +20 puntos!",
style = MaterialTheme.typography.subtitle2,
fontWeight = FontWeight.Bold,
modifier = Modifier.padding(3.dp))
}
}
}
}
}
}
}
}
}
}
In the Slider you can use the onValueChangeFinished to change the enable value:
var enable by remember { mutableStateOf(false) }
Slider(
value = sliderPosition,
onValueChange = {
sliderPosition = it
enable = true
},
onValueChangeFinished = {
completeValue
enable = false
},
//...
)
Also you can avoid to use the if statement for the Button. Just use:
Button(
//...
enabled = enable,
onClick = {
openDialog.value = !openDialog.value
}
) {
//...
}

<SOLVED> TextField New Line Issue in Alert Dialog with Jetpack Compose

I want to create an alert dialog with Jetpack Compose. In this alert dialog include a TextField component from Compose.
I created that alert dialog but there is a problem here that when I press enter button where is on the device keyboard to add a new line my content is moving to up.
How can I solve this UI issue?
Thanks in advance.
The Problem;
Here is my code;
#Composable
fun SimpleAlert(
title: String = "Ask a Question",
onDismiss: () -> Unit,
onSubmit: (text: String) -> Unit
) {
val text = remember { mutableStateOf("") }
val textHint = "Write your question..."
val textLength = remember { mutableStateOf(0) }
val isAnonymous = remember { mutableStateOf(false) }
AlertDialog(
onDismissRequest = {
onDismiss()
},
title = {
Column(
modifier = Modifier

SOLUTION ✅
To solve this issue just use Dialog instead of AlertDialog
This is definitely what you are looking for
TextField(
value = text.value,
onValueChange = {
if (it.length <= 200) {
textLength.value = it.length
text.value = it
}
},
label = {
Text(text = textHint)
},
modifier = Modifier
.padding(top = 16.dp)
.sizeIn(minHeight = 120.dp)
.background(Color.Transparent),
keyboardOptions = KeyboardOptions.Default.copy(
imeAction = ImeAction.Done
),
keyboardActions = KeyboardActions(
onDone = {
//Do something here
},
),
)

Phone keyboard doesn't popup when I click on TextField Compose in DialogFragment

Below is the code for custom TextField. I have used TextField in Fragment and DialogFragment. I am having some issues while using it in DialogFragment. The phone keyboard opens when I click on the TextField below when it is used in Fragment. But even though it focuses on the TextField, the keyboard doesn't pop up when it is used in DialogFragment.

I figured out the solution to my problem. I used Dialog Compose inside Dialog Fragment and the keyboard popped up.

compile time error: #Composable invocations can only happen from the context of a #Composable function

I have a compile time error as shown in the title
(#Composable invocations can only happen from the context of a #Composable function),
I have one card in this code so I want to show An AlertDialog after clicking the card clickable,
I know that this problem is exist in the platform,
So how can i solve this problem?
#Composable
fun Screen_A_with_WithTopBar(navController: NavController) {
Scaffold(
topBar = {
TopAppBar(
title = {
Text(text = "Top App Bar")
},
navigationIcon = {
IconButton(onClick = {
navController.navigate(Screen.Home.route)
}) {
Icon(Icons.Filled.Menu, "backIcon")
}
},
backgroundColor = MaterialTheme.colors.primary,
contentColor = Color.White,
elevation = 10.dp
)
}, content = {
Screen_A(navController)
}
)
}
#Composable
fun Screen_A(navController: NavController) {
val context = LocalContext.current
Column(
verticalArrangement = Arrangement.Center,
horizontalAlignment = Alignment.CenterHorizontally,
modifier = Modifier
.fillMaxSize()
//.background(ScreenColor)
) {
Text(
text = "Dooro",
fontSize = 42.sp
)
Spacer(modifier = Modifier.height(33.dp))
Row(
verticalAlignment = Alignment.Top,
horizontalArrangement = Arrangement.SpaceAround,
modifier = Modifier
.fillMaxWidth()
.padding(12.dp),
) {
Card(
modifier = Modifier
.width(150.dp)
.height(80.dp)
.clickable {
Alert()
},
RoundedCornerShape(7.dp),
elevation = 7.dp
//.padding(40.dp)
) {
Text(
text = "None",
fontSize = 24.sp,
fontWeight = FontWeight.Bold,
textAlign = TextAlign.Center
)
}
} // END Row
}
}
#Composable
fun Alert() {
val openDialog = remember { mutableStateOf(true) }
if (openDialog.value) {
AlertDialog(
onDismissRequest = {
openDialog.value = false
},
title = {
Text(text = "Title")
},
text = {
Text(
"This area typically contains the supportive text " +
"which presents the details regarding the Dialog's purpose."
)
},
buttons = {
Row(
modifier = Modifier.padding(all = 8.dp),
horizontalArrangement = Arrangement.Center
) {
Button(
modifier = Modifier.fillMaxWidth(),
onClick = { openDialog.value = false }
) {
Text("Dismiss")
}
}
}
)
}
}
Here you can use mutableStateOf to be able to show your Alert.
on Screen_A, you should add the following
var showAlert by mutableStateOf(false)
#Composable
private fun ShowAlert() {
if (showAlert)
Alert()
}
Finally in your Card, you will change the value of showAlert field to true.
Card(
modifier = Modifier
.width(150.dp)
.height(80.dp)
.clickable {
showAlert = true
},
RoundedCornerShape(7.dp),
elevation = 7.dp
//.padding(40.dp)
)

How can I use lazy column and lazyverticalgrid in jetpack compose?

I wanted a layout similar to
`<Scrollview>
<Relativelayout>
<Recyclerview/>(Horizontal)
<Recyclerview/>(Vertical)

</Scrollview>`

When I try to achieve it in jetpack compose. The list scrolls under it's own layout but doesn't expand making the whole scrolling. Horizontal one is fine but the vertical one tends to have a small height not making it the sameheight as the list itself.
Needed a view something like this so that the view can expand as well as scroll with the layout.
#Composable
fun NewsList() {
LazyColumn {
items(rows) { item ->
Text(
modifier = Modifier
.height(80.dp),
text = item
)
}
}
something like this you can create fr lazycolum
for gride you can try this(Not sure for this) is it right or not
LazyVerticalGrid(
cells = GridCells.Fixed(cellState),
content = {
}
}
)
Don't forget to import this library explicitly
import androidx.compose.foundation.lazy.items
#Composable
fun Conversation(messages: List<Message>) {
LazyColumn {
items(messages) { message ->
MessageCard(message)
}
}
}
