Jetpack compose date picker
Date Picker in material design components is a useful component used in an application, the user can select a year, a month, and a day, combining to form date from a calendar-like-looking box. This data is generally needed and collected in applications that require a specific date to book a movie, travel, or hotel booking or filter the data according to a specific date.
Using Date Picker we can not only select a date but also can select a range of dates.

In this article, we will learn how to implement a Date Picker in Android using Jetpack Compose.
Create a New project and select Empty Activity In my case, application name is Coding Bihar you can use any other name.
I used dependency implementation 'androidx.compose.material3:material3:1.1.1'
for Date Picker.
MainActivity
Copy this code →
package com.example.codingbihar
import android.os.Bundle
import androidx.activity.ComponentActivity
import androidx.activity.compose.setContent
import androidx.compose.foundation.layout.fillMaxSize
import androidx.compose.material3.MaterialTheme
import androidx.compose.material3.Surface
import androidx.compose.ui.Modifier
import com.example.codingbihar.ui.theme.CodingBiharTheme
class MainActivity : ComponentActivity() {
@RequiresApi(Build.VERSION_CODES.O)
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
CodingBiharTheme {
// A surface container using the 'background' color from the theme
Surface(modifier = Modifier.fillMaxSize(),
color = MaterialTheme.colorScheme.background) {
DatepickerSample()
}
}
}
}
}Create a separate file for Date Picker and named it as DatepickerSample
