I am very new to jetpack compose please help, I have use Surface() but my views are overlapping one another, I want separate view as first one should be TopHeader() and another one should be BillForm
My code is:-
class MainActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
MyApp {
//TopHeader()
MainContent()
}
}
}
}
@Composable
fun MyApp(content: @Composable () -> Unit) {
JetTipAppTheme {
// A surface container using the 'background' color from the theme
Surface(color = MaterialTheme.colors.background) {
content()
}
}
}
TopHeader function to display the pink color view in the given image
@Composable
fun TopHeader(totalPerPerson: Double = 134.0) {
Surface(
modifier = Modifier
.fillMaxWidth()
.padding(15.dp)
.height(150.dp)
.clip(shape = CircleShape.copy(all = CornerSize(12.dp))),
//.clip(shape = RoundedCornerShape(corner = CornerSize(12.dp))),
color = Color(0xFFE9D7F7)
) {
Column(
modifier = Modifier.padding(12.dp),
horizontalAlignment = Alignment.CenterHorizontally,
verticalArrangement = Arrangement.Center
) {
val total = "%.2f".format(totalPerPerson)
Text(
text = "Total per person",
style = MaterialTheme.typography.h5
)
Text(
text = "$$total",
style = MaterialTheme.typography.h4,
fontWeight = FontWeight.ExtraBold
)
}
}
}
This is MainContent function:-
@Composable
fun MainContent() {
BillForm(){ billAmt ->
Log.d("AMT","MainContent: $billAmt")
}
}
BillForm composable function
@Composable
fun BillForm(modifier: Modifier = Modifier,
onValChange: (String) -> Unit = {}
){
val totalBillState = remember{
mutableStateOf("")
}
val validState = remember(totalBillState.value) {
totalBillState.value.trim().isNotEmpty()
}
val keyboardController = LocalSoftwareKeyboardController.current
val sliderPositionState = remember {
mutableStateOf(0f) //slider will take position from zero
}
TopHeader()
Surface(
modifier = Modifier
.padding(2.dp)
.fillMaxWidth(),
shape = RoundedCornerShape(corner = CornerSize(8.dp)),
border = BorderStroke(width = 1.dp, color = Color.LightGray)
) {
Column(
modifier = Modifier.padding(6.dp),
verticalArrangement = Arrangement.Top,
horizontalAlignment = Alignment.Start
) {
InputField(
valueState = totalBillState,
labelId = "Enter Bill",
enabled = true,
isSingleLined = true,
onAction = KeyboardActions{
if (!validState)return@KeyboardActions
onValChange(totalBillState.value.trim())
keyboardController?.hide()
}
)
//if(validState){
Row(
modifier = Modifier.padding(3.dp),
horizontalArrangement = Arrangement.Start
) {
Text(text = "Split",
modifier = Modifier.align(
alignment = Alignment.CenterVertically
))
//Spacer in between text and buttons
Spacer(modifier = Modifier.width(120.dp))
//Row for Buttons
Row(modifier = Modifier.padding(horizontal = 3.dp),
horizontalArrangement = Arrangement.End
) {
RoundIconButton( imageVector = Icons.Default.Remove,
onClick = { })
Text(text = "2",
modifier = Modifier
.align(Alignment.CenterVertically)
.padding(start = 9.dp, end = 9.dp)
)
RoundIconButton( imageVector = Icons.Default.Add,
onClick = { })
}
}
//Tip Row
Row(modifier = Modifier
.padding(horizontal = 3.dp, vertical = 12.dp)
) {
Text(text = "Tip",
modifier = Modifier.align(alignment = Alignment.CenterVertically))
Spacer(modifier = Modifier.width(200.dp))
Text(text = "$33.00",
modifier = Modifier.align(alignment = Alignment.CenterVertically))
}
Column(verticalArrangement = Arrangement.Center,
horizontalAlignment = Alignment.CenterHorizontally
) {
Text(text = "33%")
Spacer(modifier = Modifier.height(14.dp))
//Slider
Slider(value = sliderPositionState.value,
onValueChange = { newVal ->
sliderPositionState.value = newVal //<- this will change the position of the slider
Log.d("Slider","BillForm: $newVal")
},
modifier = Modifier.padding(start = 16.dp, end = 16.dp),
steps = 5,
onValueChangeFinished = {
}
)
}
// }else{
// Box() {
//
// }
// }
}
}
}
TopHeader composable view:-
BillForm view:-
What I want is like this given image:-
CodePudding user response:
Use a Column(){}
Composable for that purpose.
You can follow these basics that can help you to organize your composables and understand how its work.
