More Functionalities of Material Design Date Picker in Android (original) (raw)

Last Updated : 23 Jul, 2025

As discussed in the Material Design Date Picker in Android it offers many functionalities to users and is easy to implement for developers. So in this article, we are going to discuss more functionalities of material design date picker with examples. Note that the UI part will be the same as in the Part-1 article. We are going to work with the Java file only.

Functionality 1: Block all the dates before today's date

This feature is very useful for a developer for avoiding users from choosing the wrong date. A sample GIF is given below to get an idea about what we are going to do in this functionality.

Go to the MainActivity.java file, and refer to the following code. Below is the code for the MainActivity.java file. Comments are added inside the code to understand the code in more detail.

Java `

import android.annotation.SuppressLint; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.TextView; import androidx.appcompat.app.AppCompatActivity; import com.google.android.material.datepicker.CalendarConstraints; import com.google.android.material.datepicker.DateValidatorPointForward; import com.google.android.material.datepicker.MaterialDatePicker; import com.google.android.material.datepicker.MaterialPickerOnPositiveButtonClickListener;

public class MainActivity extends AppCompatActivity {

// button to open the material date picker dialog
private Button mPickDateButton;

// textview to preview the selected date
private TextView mShowSelectedDateText;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // register all the UI widgets with their
    // appropriate IDs
    mPickDateButton = findViewById(R.id.pick_date_button);
    mShowSelectedDateText = findViewById(R.id.show_selected_date);

    // create the calendar constraint builder
    CalendarConstraints.Builder calendarConstraintBuilder = new CalendarConstraints.Builder();
    
    // set the validator point forward from june
    // this mean the all the dates before the June month
    // are blocked
    calendarConstraintBuilder.setValidator(DateValidatorPointForward.now());

    // instantiate the Material date picker dialog
    // builder
    final MaterialDatePicker.Builder materialDatePickerBuilder = MaterialDatePicker.Builder.datePicker();
    materialDatePickerBuilder.setTitleText("SELECT A DATE");

    // now pass the constrained calendar builder to
    // material date picker Calendar constraints
    materialDatePickerBuilder.setCalendarConstraints(calendarConstraintBuilder.build());

    // now build the material date picker dialog
    final MaterialDatePicker materialDatePicker = materialDatePickerBuilder.build();

    // handle the Select date button to open the
    // material date picker
    mPickDateButton.setOnClickListener(
            new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    // show the material date picker with
                    // supportable fragment manager to
                    // interact with dialog material date
                    // picker dialog fragments
                    materialDatePicker.show(getSupportFragmentManager(), "MATERIAL_DATE_PICKER");
                }
            });

    materialDatePicker.addOnPositiveButtonClickListener(
            new MaterialPickerOnPositiveButtonClickListener() {
                @SuppressLint("SetTextI18n")
                @Override
                public void onPositiveButtonClick(Object selection) {
                    // now update the selected date preview
                    mShowSelectedDateText.setText("Selected Date is : " + materialDatePicker.getHeaderText());
                }
            });
}

}

Kotlin

class MainActivity : AppCompatActivity() { // button to open the material date picker dialog private var mPickDateButton: Button? = null

// textview to preview the selected date
private var mShowSelectedDateText: TextView? = null
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    // register all the UI widgets with their
    // appropriate IDs
    mPickDateButton = findViewById(R.id.pick_date_button)
    mShowSelectedDateText = findViewById(R.id.show_selected_date)

    // create the calendar constraint builder
    val calendarConstraintBuilder = CalendarConstraints.Builder()

    // set the validator point forward from june
    // this mean the all the dates before the June month
    // are blocked
    calendarConstraintBuilder.setValidator(DateValidatorPointForward.now())

    // instantiate the Material date picker dialog
    // builder
    val materialDatePickerBuilder: MaterialDatePicker.Builder<*> =
        MaterialDatePicker.Builder.datePicker()
    materialDatePickerBuilder.setTitleText("SELECT A DATE")

    // now pass the constrained calendar builder to
    // material date picker Calendar constraints
    materialDatePickerBuilder.setCalendarConstraints(calendarConstraintBuilder.build())

    // now build the material date picker dialog
    val materialDatePicker = materialDatePickerBuilder.build()

    // handle the Select date button to open the
    // material date picker
    mPickDateButton.setOnClickListener(
        object : OnClickListener() {

                // show the material date picker with

                materialDatePicker.show(supportFragmentManager, "MATERIAL_DATE_PICKER")
            }
        })
    materialDatePicker.addOnPositiveButtonClickListener { // now update the selected date preview
        mShowSelectedDateText.setText("Selected Date is : " + materialDatePicker.headerText)
    }
}

} // This code is added by Ujjwal KUmar Bhardwaj

Functionality 2: Select the today's date as the default selection as soon as the material date picker dialog opens

Have a look at the following image.

Go to the MainActivity.java file, and refer to the following code. Below is the code for the MainActivity.java file. Comments are added inside the code to understand the code in more detail.

Java `

import android.annotation.SuppressLint; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.TextView; import androidx.appcompat.app.AppCompatActivity; import com.google.android.material.datepicker.MaterialDatePicker; import com.google.android.material.datepicker.MaterialPickerOnPositiveButtonClickListener;

public class MainActivity extends AppCompatActivity {

// button to open the material date picker dialog
private Button mPickDateButton;

// textview to preview the selected date
private TextView mShowSelectedDateText;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // register all the UI widgets with their
    // appropriate IDs
    mPickDateButton = findViewById(R.id.pick_date_button);
    mShowSelectedDateText = findViewById(R.id.show_selected_date);

    // now create the instance of the regular material
    // date picker
    MaterialDatePicker.Builder materialDateBuilder = MaterialDatePicker.Builder.datePicker();

    // get the today's date from the method
    // todayInUtcMilliseconds()
    long today = MaterialDatePicker.todayInUtcMilliseconds();

    // now define the properties of the

    final MaterialDatePicker materialDatePicker = materialDateBuilder.build();

    // handle select date button which opens the

    mPickDateButton.setOnClickListener(
            new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    // now show the material date picker

                }
            });

    // now handle the positive button click from the

    materialDatePicker.addOnPositiveButtonClickListener(
            new MaterialPickerOnPositiveButtonClickListener() {
                @SuppressLint("SetTextI18n")
                @Override
                public void onPositiveButtonClick(Object selection) {
                    // now update selected date preview text
                    mShowSelectedDateText.setText("Selected Date is : " + materialDatePicker.getHeaderText());

Functionality 3: Make the user, select a date within bounds

For example, select the date from March 2020 to December 2020. A sample GIF is given below to get an idea about what we are going to do in this functionality.

    calendar.set(Calendar.MONTH, Calendar.MARCH);
    long march = calendar.getTimeInMillis();

    // now set the ending bound from current month to
