Android DatePicker is an interface component that allows the user to select a date and ensure that the user input data are valid.

DatePicker has two modes with different interface.

android:datePickerMode="calendar" (Default)
android:datePickerMode="spinner"

DatePickerDialog allows the user to select a valid date and hide it after making a choice. It saves more space of your application than DatePicker.

android:datePickerMode="calendar"

<DatePicker
    android:id="@+id/datePicker"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:datePickerMode="calendar"  />

Landscape Screen

android:datePickerMode="spinner"

In spinner mode, DatePicker consists of two parts, the left side is a block of three Spinners that permits the user to adjust the month, day and year. The other is the simpler CalendarView than it is in calendar mode.

<DatePicker
    android:id="@+id/datePicker"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="16dp"
    android:datePickerMode="spinner" />

DatePicker [spinner mode] default.

You can use android:calendarViewShown="false" to hide the right-hand side CalendarView component.

[android:calendarViewShown="false"]

<DatePicker
    android:id="@+id/datePicker"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:calendarViewShown="false"
    android:datePickerMode="spinner" />

[android:calendarViewShown="false"]

Or you can use android:spinnersShown="false" to hide the block (containing three Spinners) on your left.

[android:spinnersShown="false"]

<DatePicker
    android:id="@+id/datePicker"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="16dp"
    android:datePickerMode="spinner"
    android:spinnersShown="false" />

[android:spinnersShown="false"]

Example preview:

First, create a new project on Android Studio:

File > New > New Project > Empty Activity
- Name: DatePickerExample
- Package name: org.o7planning.datepickerexample
- Language: Java

DatePicker is not available in the Palette designing window, so you need to use an XML code in order to add it to the interface and later adjust its position and attributes visually.

DatePicker (Calendar Mode)

<DatePicker
    android:id="@+id/datePicker"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:datePickerMode="calendar"  />

Well, it is time to adjust the position of components in the interface:

And set ID, and Text for the components as follows:

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <DatePicker
        android:id="@+id/datePicker"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="8dp"
        android:datePickerMode="calendar"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <LinearLayout
        android:id="@+id/linearLayout"

        android:orientation="horizontal"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/datePicker">

        <EditText
            android:id="@+id/editText_date"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:ems="10"
            android:hint="dd-MM-yyyy"
            android:inputType="date" />

        <Button
            android:id="@+id/button_date"

            android:text="Get Date" />
    </LinearLayout>
