Date Picker

In Android, you can use “android.widget.DatePicker” class to render a date picker component to select day, month and year in a pre-defined user interface.

In this tutorial, we show you how to render date picker component in current page via android.widget.DatePicker, and also in dialog box via android.app.DatePickerDialog. In addition, we also show you how to set a date in date picker component.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"
