DatePickerTimeline

A linear Android date picker library written in Jetpack compose.
Inspired by https://pub.dev/packages/date_picker_timeline

Installation

Add the dependency to your build.gradle or build.gradle.kts file

repositories {
    maven { url 'https://jitpack.io' }
}

dependencies{
    implementation ("com.github.Rafsanjani:datepickertimeline:<latest_version>")
}

Usage

For a horizontal date picker with no customization

DatePickerTimeLine(
	modifier = Modifier,
	onDateSelected = {selectedDate: LocalDate->
		//do something with selected date
	}
) 

For a vertical date picker with no customization

import com.foreverrafs.datepicker.Orientation

DatePickerTimeLine(
	modifier = Modifier,
	orientation = Orientation.Vertical,
	onDateSelected = {selectedDate: LocalDate->
		//do something with selected date
	}
) 

You can pass an optional state to the picker and specify the initial selected date

DatePickerTimeLine(
	modifier = Modifier,
	state = rememberDatePickerState(initialDate = LocalDate.now()),
	onDateSelected = { selectedDate: LocalDate ->
		//do something with selected date
	}
) 

To customize the full list of properties

import com.foreverrafs.datepicker.Orientation

val today = LocalDate.now()
val datePickerState =  
    rememberDatePickerState(initialDate = LocalDate.now())
    
DatePickerTimeline(
  modifier = Modifier.wrapContentSize(),  
  onDateSelected = { selectedDate: LocalDate ->
		// do something with the selected date
  },  
  backgroundColor = Color.Yellow,  // the main background color
  state = datePickerState,  
  orientation = Orientation.Horizontal,  
  selectedBackgroundColor = Color.Green, // The background of the currently selected date  
  selectedTextColor = Color.White,  // Text color of currently selected date
  dateTextColor = Color.Black, //Text color of all dates  
  eventDates = listOf(  
        today.plusDays(1),  
        today.plusDays(3),  
        today.plusDays(5),  
        today.plusDays(8),  
  ),   
  todayLabel = {  
      Text(  
          modifier = Modifier.padding(10.dp),  
          text = "Today",  
          color = Color.White,  
          style = MaterialTheme.typography.h6  
      )
    },  
  pastDaysCount = 10,  // The number of previous dates to display, relative to the initial date. Defaults to 120
  eventIndicatorColor = Color.Brown // Indicator color for marked event dates.
)

Scrolling to different dates

You can store the DatePickerState object into a variable and use it to perform smooth scrolling to any date. This is very similar to how LazyListState works. If you try to scroll to an invalid date as constrained by the pastDaysCount property, you are scrolled to the first valid date in the calendar instead.

val today = LocalDate.now()
val datePickerState =  
    rememberDatePickerState(initialDate = LocalDate.now())
    
Column{
  DatePickerTimeline(
    state = datePickerState
  )
  
  Button(
    onClick = {
      // Scroll to Jan 01, 2022
      datePickerState.smoothScrollTodate(LocalDate.of(2022, 1, 1)
    }
  ){
    Text("Go to different date")
  }
}
