activity_calender.xml

<?xml version="1.0" encoding="utf-8"?> <linearlayout  xmlns:android="http://schemas.android.com/apk/res/android"           xmlns:tools="http://schemas.android.com/tools"           android:orientation="vertical"           android:layout_width="match_parent"           android:layout_height="match_parent"           android:paddingleft="@dimen/activity_horizontal_margin"           android:paddingright="@dimen/activity_horizontal_margin"           android:paddingtop="@dimen/activity_vertical_margin"           android:paddingbottom="@dimen/activity_vertical_margin"           tools:context=".basicactivity" >  <com.prolificinteractive.materialcalendarview.materialcalendarview     android:id="@+id/calendarview"     android:layout_width="match_parent"     android:layout_height="wrap_content"     />  <textview     android:id="@+id/textview"     android:layout_margin="16dp"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_gravity="center"     android:text=""     android:textcolor="#000000"     android:textappearance="?android:attr/textappearancelarge"     /> <button     android:id="@+id/ok_button"     android:layout_width="150dp"     android:layout_height="50dp"     android:text="ok"     android:textcolor="@color/white"     android:padding="5dp"     android:background="@drawable/btn_calender_bg"     android:positivebuttontext="ok"     android:layout_gravity="center_horizontal"/>
