I am trying to make an alarm to be scheduled according to the data received from a DatePicker and a TimePicker in JetPack Compose, this is the current code:
class MainActivity : ComponentActivity() {
lateinit var navController: NavHostController
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
navController = rememberNavController()
NotePadReminderTheme {
SetupNavGraph(navController = navController)
}
}
}
}
@RequiresApi(Build.VERSION_CODES.M)
fun createAlarm(context: Context,time:Long){
val alarmManager =context.getSystemService(Context.ALARM_SERVICE) as? AlarmManager
val intent =Intent(context, AlarmReceiver::class.java)
Log.d("receivedtime","time $time")
val pendingIntent = PendingIntent.getBroadcast(context, Date().seconds, intent, PendingIntent.FLAG_IMMUTABLE)
alarmManager?.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP, time, pendingIntent)
Toast.makeText(context,"Alarma creada",Toast.LENGTH_LONG).show()
}
@RequiresApi(Build.VERSION_CODES.M)
@Composable
fun AddPage(navController: NavController, vm: TaskViewModel = viewModel()) {
val scope= rememberCoroutineScope()
val title = remember {
mutableStateOf("")
}
val description = remember {
mutableStateOf("")
}
val date = remember {
mutableStateOf("")
}
val time = Calendar.getInstance()
val iscompleted = remember {
mutableStateOf(false)
}
val context = LocalContext.current
Column(
modifier = Modifier
.fillMaxSize()
.padding(top = 30.dp),
horizontalAlignment = Alignment.CenterHorizontally
) {
Text(
text = "Agregar Tarea",
style = NoteTheme.typography.h1
)
RowOfThis(title, "Título", true)
RowOfThis(description, "Descripción", false)
Row(modifier = Modifier.fillMaxWidth(), verticalAlignment = Alignment.CenterVertically) {
DatePick(date)
}
Row(modifier = Modifier.fillMaxWidth(), verticalAlignment = Alignment.CenterVertically) {
TimePick(time)
}
Button(
onClick = {
if (title.value.isNullOrBlank() || description.value.isNullOrBlank() ||
date.value.isNullOrBlank()
) {
Log.d("date","date:${date.value}")
Toast.makeText(context, "Por favor ingrese todos los datos", Toast.LENGTH_LONG)
.show()
return@Button
}
vm.task.value.title = title.value
vm.task.value.description = description.value
vm.task.value.date = date.value
vm.task.value.time = time.timeInMillis
Log.d("tmepickerreceived","date:${time.timeInMillis}")
scope.launch {
vm.createTask(context, vm.task.value)
createAlarm(context, time=time.timeInMillis). //here set the alarm ****************
Toast.makeText(context, "Tarea creada correctamente", Toast.LENGTH_LONG).show()
vm.resetTask()
}
},
colors = ButtonDefaults.buttonColors(backgroundColor = Color.Blue)
) {
Text(text = "Guardar", color = Color.White, style = NoteTheme.typography.subtitle)
}
}
}
@Composable
fun RowOfThis(value: MutableState<String>, label: String, single: Boolean) {
val focusManager = LocalFocusManager.current
Row(
modifier = Modifier
.fillMaxWidth()
.padding(10.dp)
) {
TextField(
modifier = Modifier
.fillMaxWidth()
.border(BorderStroke(width = 1.dp, color = Color.Black)),
singleLine = single,
maxLines = 3,
textStyle = NoteTheme.typography.body,
value = value.value, onValueChange = {
value.value = it
}, label = {
Text(
text = label, textAlign = TextAlign.Start,
color = Color.DarkGray,
style = NoteTheme.typography.subtitle
)
},
keyboardOptions = KeyboardOptions(imeAction = ImeAction.Next),
colors = TextFieldDefaults.textFieldColors(backgroundColor = Color.White),
keyboardActions = KeyboardActions(onNext =
{ focusManager.moveFocus((FocusDirection.Next)) })
)
}
}
@Composable
fun DatePick(mDate:MutableState<String>) {
val mContext = LocalContext.current
val mYear: Int
val mMonth: Int
val mDay: Int
val mCalendar = Calendar.getInstance()
mYear = mCalendar.get(Calendar.YEAR)
mMonth = mCalendar.get(Calendar.MONTH)
mDay = mCalendar.get(Calendar.DAY_OF_MONTH)
mCalendar.time = Date()
val mDatePickerDialog = DatePickerDialog(
mContext,
{ _: DatePicker, mYear: Int, mMonth: Int, mDayOfMonth: Int ->
mDate.value = "$mDayOfMonth/${mMonth + 1}/$mYear"
}, mYear, mMonth, mDay
)
mDatePickerDialog.datePicker.minDate=Date().time
Log.d("datepicker","dateset:${mDate.value}")
Button(modifier = Modifier
.padding(7.dp)
.fillMaxWidth(0.5f), onClick = {
mDatePickerDialog.show()
}, colors = ButtonDefaults.buttonColors(backgroundColor = Color(0XFF227093))) {
Text(text = "Seleccionar fecha",
color = Color.White, style = NoteTheme.typography.subtitle)
}
Text(text = "${mDate.value}",style = NoteTheme.typography.caption, fontSize = 22.sp, color = Color(0XFF227093))
}
@Composable
fun TimePick(mCalendar:Calendar) {
val mContext = LocalContext.current
val mHour = mCalendar[Calendar.HOUR_OF_DAY]
val mMinute = mCalendar[Calendar.MINUTE]
val mTime = remember { mutableStateOf("") }
val mTimePickerDialog = TimePickerDialog(
mContext,
{_, mHour : Int, mMinute: Int ->
mTime.value = "$mHour:$mMinute"
}, mHour, mMinute, false
)
Log.d("tmepicker","time:${mCalendar.timeInMillis}")
Button(modifier = Modifier
.padding(7.dp)
.fillMaxWidth(0.5f), onClick = {
mTimePickerDialog.show()
}, colors = ButtonDefaults.buttonColors(backgroundColor = Color(0XFF2c2c54))) {
Text(text = "Seleccionar hora",
color = Color.White, style = NoteTheme.typography.subtitle)
}
Text(text = "${mTime.value}",style = NoteTheme.typography.caption, fontSize = 22.sp, color = Color(0XFF2c2c54))
}
However, the problem I have is that when the alarm is configured, that is, when I call the setExactAndAllowWhileIdle() method, the alarm is executed once and it should not be so, but at the time and date of the data sent (time). Any idea why this happens??
