The show() Method

The show() method is used to display the date picker with full flexibility. Here's a detailed breakdown of the parameters:

fun show(
    context: Context,
    date: String,
    displayView: View? = null, 
    offset: String = "0-0-0",
    upperLimit: String = today(), 
    todo: () -> Unit = {} 
)

Parameters:

• context: The Context in which the date picker will be displayed (usually Activity or Fragment).
• date: The date to show initially, in the format dd-MM-yyyy.
• displayView: A TextView or Button whose text will be updated with the selected date. If not provided, no view will be updated.
• offset: A string that defines the offset for date selection. The format is "dd-mm-yyyy". For example, "0-0-5" will show dates from 5 years ago.
• upperLimit: The latest date a user can select, in the format dd-MM-yyyy. By default, this is today's date.
• todo: An optional callback that will be called after a date is selected. This allows you to perform actions after the date is picked.

Example:

val datePicker = CustomizableDatePicker()
datePicker.show(
    this,
    "20-10-2023", // Default date
    v as Button, // Button to display the selected date
    offset = "0-0-5", // Show dates from 5 years ago
    upperLimit = "31-12-2025" // Limit to dates up to 31st December 2025
) {
    // Code to run after date selection
}

DateManager Class

The DateManager class provides utility functions for managing and formatting dates.

Key Methods:

• today(): Returns today's date in dd-MM-yyyy format.

  val currentDate = DateManager.today() // "21-11-2024"

• formatDate(date: String, currentFormat: String, finalFormat: String): Formats a given date from one format to another.

  val formattedDate = DateManager.formatDate("21-11-2024", "dd-MM-yyyy", "yyyy/MM/dd")
