How can select one out of 4 composabel in compose? - kotlin

Suppose I have four Button or Composable in a row, I want to select one and deselect the other, not like the radio button but behave exactly like that.
#Composable
fun ButtonSet(modifier: Modifier = Modifier) {
Row(
modifier = modifier
.padding(start = 60.dp, end = 60.dp)
.fillMaxWidth(),
horizontalArrangement = Arrangement.SpaceEvenly,
) {
val button1 = remember { mutableStateOf(false) }
val button2 = remember { mutableStateOf(false) }
val button3 = remember { mutableStateOf(false) }
val button4 = remember { mutableStateOf(false) }
val buttonList = listOf<Any>(button1, button2, button3, button4)
val activeButton = remember {
mutableStateOf(true)
}
if (button1.value || button2.value || button3.value || button4.value) {
activeButton.value = false
} else if (button1.value) {
button1.value = !button1.value
} else if (button2.value) {
button2.value = !button2.value
} else if (button3.value) {
button3.value = !button3.value
} else if (button4.value) {
button4.value = !button4.value
}
GoalkeeperButton(button1.value)
GoalkeeperButton(button2.value)
GoalkeeperButton(button3.value)
GoalkeeperButton(button4.value)
}
}
#Composable
fun GoalkeeperButton(
active: Boolean = false,
#SuppressLint("ModifierParameter") modifier: Modifier = Modifier,
) {
val buttonState = remember {
mutableStateOf(active)
}
if (!buttonState.value) {
ButtonUnActive() {}
} else {
ButtonActive()
}
RadioButton(selected =, onClick = { /*TODO*/ })
}
#Composable
fun ButtonActive(active: Boolean = true) {
val button = painterResource(id = R.drawable.bttn_pressed)
val gloves = painterResource(id = R.drawable.blue_hands)
val buttonState = remember {
mutableStateOf(active)
}
Column(
modifier = Modifier
.wrapContentWidth()
.height(130.dp)
) {
Image(
painter = gloves,
contentDescription = null,
contentScale = ContentScale.FillBounds,
modifier = Modifier
.size(width = 135.dp, height = 70.dp)
)
Image(
painter = button,
contentDescription = null,
contentScale = ContentScale.FillBounds,
modifier = Modifier
.clickable(onClick = {})
.size(width = 107.dp, height = 65.dp)
)
}
}
#Composable
fun ButtonUnActive(
state: Boolean = false,
onclick: () -> Unit,
) {
val button = painterResource(id = R.drawable.bttn)
var unActiveState by remember {
mutableStateOf(state)
}
Image(
painter = button,
contentDescription = null,
contentScale = ContentScale.FillBounds,
modifier = Modifier
.clickable(
onClick = {
onclick()
},
)
.size(width = 107.dp, height = 65.dp)
)
}
This is what I tried, but I know it's very bad code, please suggest a better and best way.

Whenever I am trying to show Image() of my soul object I am getting glitches and my screens takes more time to load itself.
I am storing image as string in local room database and trying to retrieve it back converting it to bitmapImage.
Code for conversation.
fun getBase64StringToImage(base64String: String): Bitmap {
val decodedString: ByteArray = Base64.decode(base64String, Base64.DEFAULT)
val decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.size)
return decodedByte
// this is taking a lot of time and making my Ui performance dull.
}
Is there any way I can achieve this functionality with good performance. Like loading Image in separate scope or anything else.
I have already tried using rememberImagePainter and Glide Coil. rememberImagePainter making my performance worst.
Please feel free to give me suggestions, I am still in learning stage.
Thanks in advance.

#Update ROOM Database using Jetpack Compose

I'm am making a note app using kotlin jetpack compose. Currently, I'm working on an update feature. I'm trying to update a note in ROOM Database but it doesn't update. I already read and follow some tutorials from documentation and youtube, however, I still haven't solved it.
Here is my code:
Data
#RequiresApi(Build.VERSION_CODES.O)
#Entity(tableName = "KeepNotesTable")
data class NoteData (
#PrimaryKey
val id: String = UUID.randomUUID().toString(),
#ColumnInfo(name = "noteTitle")
var title: String,
#ColumnInfo(name = "noteDescription")
var description: String,
#ColumnInfo(name = "noteDate")
val date: Date = Date.from(Instant.now())
)
DAO
#Update(onConflict = OnConflictStrategy.REPLACE)
suspend fun updateNote(note: NoteData)
Repository
suspend fun updateNote(note: NoteData) = noteDatabaseDao.updateNote(note)
ViewModel
fun updateNote(note: NoteData) = viewModelScope.launch { repository.updateNote(note) }
Navigation
#RequiresApi(Build.VERSION_CODES.O)
#Composable
fun ScreenNavigation(noteViewModel: NoteViewModel = viewModel()) {
val noteList = noteViewModel.noteList.collectAsState().value
val navController = rememberNavController()
NavHost(navController = navController, startDestination = Screen.MainScreen.name) {
composable(Screen.MainScreen.name){
MainScreen(navController = navController, noteList = noteList, removeNote = { noteViewModel.removeNote(it) })}
composable(Screen.AddNoteScreen.name){
AddNoteScreen(navController = navController, addNote = { noteViewModel.addNote(it) })
}
composable(Screen.UpdateNoteScreen.name + "/{noteId}",
arguments = listOf(navArgument(name = "noteId") {type = NavType.StringType})
) { backStackEntry ->
UpdateNoteScreen(
noteList = noteList,
navController = navController,
updateNote = { noteViewModel.updateNote(it) },
NoteId = backStackEntry.arguments?.getString("noteId")
)
}
}
}
UpdateNoteScreen
#RequiresApi(Build.VERSION_CODES.O)
#Composable
fun UpdateNoteScreen(
noteList: List<NoteData>,
navController: NavController,
updateNote: (NoteData) -> Unit,
NoteId: String?,
) {
val fetchNote = noteList.filter { note ->
note.id == NoteId
}
val note = fetchNote.first()
var noteTitle = note.title
var noteDescription = note.description
var newTitle = ""
var newDescription = ""
var title by remember {
mutableStateOf(noteTitle + newTitle)
}
var description by remember {
mutableStateOf(noteDescription + newDescription)
}
val context = LocalContext.current
Surface(
modifier = Modifier.fillMaxSize(),
color = MaterialTheme.colors.primaryVariant) {
Column(
verticalArrangement = Arrangement.Center,
horizontalAlignment = Alignment.CenterHorizontally) {
Card(
contentColor = MaterialTheme.colors.primary,
backgroundColor = MaterialTheme.colors.background,
elevation = 8.dp,
modifier = Modifier
.fillMaxWidth()
.padding(start = 10.dp, end = 10.dp, top = 20.dp, bottom = 20.dp)) {
Column(
horizontalAlignment = Alignment.CenterHorizontally,
modifier = Modifier
.fillMaxWidth()
.padding(start = 15.dp, end = 15.dp, top = 10.dp, bottom = 40.dp)) {
InputText(
modifier = Modifier.fillMaxWidth(),
text = title,
label = "",
onTextChange = {
newTitle = it
title = newTitle
}
)
Spacer(modifier = Modifier.height(10.dp))
InputText(
modifier = Modifier
.fillMaxWidth()
.fillMaxHeight(0.5f),
text = description,
label = "",
maxLine = 1000,
imeAction = ImeAction.None,
onTextChange = {
newDescription = it
description = newDescription
}
)
}
}
Row() {
DiscardButton(text = "Cancel", onClick = {
navController.navigate(route = Screen.MainScreen.name)
})
Spacer(modifier = Modifier.width(10.dp))
SaveButton(text = "Update", onClick = {
if (title.isNotEmpty() && description.isNotEmpty()) {
updateNote(NoteData(title = title, description = description))
navController.navigate(route = Screen.MainScreen.name)
Toast.makeText(context, "Successfully Updated", Toast.LENGTH_SHORT).show()
} else {
Toast.makeText(context, "Fill the Title and Description", Toast.LENGTH_SHORT).show()
}
})
}
}
}
}
I reviewed my code again and noticed that an id parameter is needed to pass in the updateNote() to find and update the specific note. Therefore,
updateNoteScreen
updateNote(NoteData(title = title, description = description)
should be
updateNote(NoteData(id = note.id, title = title, description = description)

Jetpack compose scrollable table

I need to have a component that scrolls vertically and horizontally.
Here is what I did so far:
#Composable
fun Screen() {
val scope = rememberCoroutineScope()
val scrollOffset = remember {
mutableStateOf(value = 0F)
}
LazyColumn(
modifier = Modifier.fillMaxSize(),
verticalArrangement = Arrangement.spacedBy(space = 16.dp)
) {
items(10) {
SimpleRow(
onScrollOffsetChange = {
scrollOffset.value = it
}
)
}
}
}
#Composable
private fun SimpleRow(
onScrollOffsetChange: (Float) -> Unit,
) {
val lazyRowState = rememberLazyListState()
LazyRow(
modifier = Modifier.fillMaxWidth(),
state = lazyRowState
) {
item {
Text(
text = "firstText"
)
}
for (i in 1..30) {
item {
Text(text = "qwerty")
}
}
}
}
When anyone of these SimpleRow is scrolled I want to scroll all of the SimpleRows together.
And I do not know how many SimpleRows I have because they came from our server.
Is there any kind of composable or trick that can do it for me?
You can use multiple rows inside a column that scrolls horizontally and vertically, like this:
#Composable
fun MainContent() {
val scrollStateHorizontal = rememberScrollState()
val scrollStateVertical = rememberScrollState()
Column(
modifier = Modifier
.fillMaxSize()
.verticalScroll(state = scrollStateVertical)
.horizontalScroll(state = scrollStateHorizontal)
) {
repeat(40){ c ->
Row {
repeat(40){ r ->
Item("col: $c | row: $r")
}
}
}
}
}
#Composable
fun Item(text: String) {
Text(
modifier = Modifier
.padding(5.dp)
.background(Color.Gray),
text = text,
color = Color.White
)
}

How to dynamically create menu in jetpack compose

I'm wanting the menu to load the data that comes from the database. This is being static manually, does anyone have any idea how I can do this? Here's my current structure. Anything if you need more code details I can show you
My method:
#Composable
private fun DrawerContent(
scope: CoroutineScope,
scaffoldState:ScaffoldState,
navController: NavController
){
val items = listOf(
Screen.Entry1,
Screen.Entry2,
Screen.Entry3
)
Column(modifier= Modifier
.background(colorResource(id = R.color.pastel_green))
.fillMaxWidth()
.fillMaxHeight(),
horizontalAlignment = Alignment.CenterHorizontally) {
Text(
"Menu", style = MaterialTheme.typography.h5,
modifier = Modifier.padding(bottom = 20.dp,top=20.dp),
color = colorResource(id = R.color.marron)
)
val current by navController.currentBackStackEntryAsState()
val currentRoute = current?.destination
items.forEach { screen ->
var selected = currentRoute?.hierarchy?.any { it.route == screen.route } == true
val selectedColor = if (selected) colorResource(id = R.color.cinza) else Color.Transparent
val colorfont = if (selected) colorResource(id = R.color.white) else colorResource(id = R.color.cinza)
Row(modifier = Modifier
.fillMaxWidth()
.height(32.dp)
.background(selectedColor)
.clickable {
selected =
currentRoute?.hierarchy?.any { it.route == screen.route } == true
scope.launch { scaffoldState.drawerState.close() }
navController.navigate(screen.route) {
// Pop up to the start destination of the graph to
// avoid building up a large stack of destinations
// on the back stack as users select items
popUpTo(navController.graph.findStartDestination().id) {
saveState = true
}
// Avoid multiple copies of the same destination when
// reselecting the same item
launchSingleTop = true
// Restore state when reselecting a previously selected item
restoreState = true
}
}) {
Text(stringResource(screen.resourceString),fontSize = 20.sp,
color= colorfont)
}
}
}
}
Class Screen:
sealed class Screen(val route: String, #StringRes val resourceString: Int,#IdRes val resourceId:Int) {
object Entry1 : Screen("entry1", R.string.entry1, R.id.entry1)
object Entry2 : Screen("entry2", R.string.entry2, R.id.entry2)
object Entry3 : Screen("entry3", R.string.entry3, R.id.entry3)
}
solved
My Code:
NavHost(
navController = navController,
// 1st change: Set startDestination to the exact string of route
startDestination = "entry${items[0].category_id}/{$ARG_ID}", // NOT "dynamic/1", provide arguments via defaultValue
) {
items.forEach { screen ->
composable(
route = "entry${screen.category_id}/{$ARG_ID}",
// 2nd change: Set startDestination argument via defaultValue
arguments = listOf(navArgument(ARG_ID) {
type = NavType.IntType; defaultValue =
screen.category_id
}),
) {
entryAbstract.Entry1(id = it.arguments?.getInt(ARG_ID))
}
}
}
companion object
{
const val ARG_ID = "id"
}
My method composable
#Composable
private fun DrawerContent(scope: CoroutineScope,scaffoldState:ScaffoldState

Observing viewmodel's liveData as state doesn't trigger a recomposition of the composable

A colleague of mine has written the following code:
Viewmodel:
class CallMeBackViewModel(
private val ewayControllerUseCase: EwayControllerUseCase,
private val accountControllerUseCase: AccountControllerUseCase
) : ViewModel() {
val accountDetails = MutableLiveData<AccountDetailsResponse>()
val contactForm = CallMeBackForm()
init {
val accountId = App.instance.appContext.getPreferenceThroughKeystore(PreferenceKeys.ACCOUNT_ID.key)
contactForm.timeframe = "09:00 - 11:00"
if (accountId != "null") {
getAccountDetails(accountId)
}
}
private fun getAccountDetails(accountId: String) {
viewModelScope.launch(Dispatchers.IO) {
when (val response = accountControllerUseCase.getAccountDetails(accountId)) {
is ResponseResult.Success -> {
accountDetails.postValue(response.data!!)
fillContactFormByAccount(response.data!!)
}
is ResponseResult.Error -> {
Log.d("GET_ACCOUNT_DETAILS_ERROR", "Network Call Failed With Exception: " + response.exception.message)
}
}
}
}
private fun fillContactFormByAccount(accountDetailsResponse: AccountDetailsResponse) {
contactForm.firstName = accountDetailsResponse.firstName!!
contactForm.lastName = accountDetailsResponse.lastName!!
contactForm.phoneNumber = accountDetailsResponse.phone1!!
contactForm.accountId = accountDetailsResponse.accountId!!
}
#ExperimentalFoundationApi
#ExperimentalMaterialApi
fun submitCallbackForm(activity: MainActivity) {
viewModelScope.launch(Dispatchers.IO) {
when (val response = ewayControllerUseCase.submitCallbackForm(contactForm)) {
is ResponseResult.Success -> {
onSuccessfulSubmission(activity)
}
is ResponseResult.Error -> {
Log.d("CALLBACK_FORM_SUBMISSION_ERROR", "Network Call Failed With Exception: " + response.exception.message)
}
}
}
}
#ExperimentalFoundationApi
#ExperimentalMaterialApi
private suspend fun onSuccessfulSubmission(activity: MainActivity) {
withContext(Dispatchers.Main) {

}
}
}
He basically fetches some form data and when received, updates the accountDetails live data with them. Now in the composable screen he observes this field as a state like so :

I noticed the seemingly useless if statement around the form, but it seems to be the only thing forcing the recomposition of the Form composable. I thought that when a new accountDetails instance is posted inside an observable state, that this would trigger any composables that depend on it to recompose. What am I missing?
