  I use Collapse Toolbar with CalendarView. I use this library for CalendarView <code>com.prolificinteractive:material-calendarview:1.0.1</code> And this is my xml code:</p>
  
  <pre><code>&lt;android.support.design.widget.CoordinatorLayout
          xmlns:android="http://schemas.android.com/apk/res/android"
          xmlns:app="http://schemas.android.com/apk/res-auto"
          android:id="@+id/rootLayout"
          android:layout_width="match_parent"
          android:layout_height="match_parent"&gt;
  
      &lt;android.support.design.widget.AppBarLayout
          android:layout_width="match_parent"
          android:layout_height="@dimen/app_bar_height"
          android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
          android:id="@+id/appbar"&gt;
  
          &lt;android.support.design.widget.CollapsingToolbarLayout
              android:id="@+id/collapsingToolbarLayout"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              app:contentScrim="?attr/colorPrimary"
              app:expandedTitleMarginStart="@dimen/expanded_toolbar_title_margin_start"
              app:layout_scrollFlags="scroll|exitUntilCollapsed"&gt;
  
              &lt;com.prolificinteractive.materialcalendarview.MaterialCalendarView
                  android:id="@+id/calendarView"
                  android:layout_width="match_parent"
                  android:layout_height="wrap_content"
                  app:mcv_showOtherDates="all"
                  app:mcv_selectionColor="#00F"&gt;
  
              &lt;/com.prolificinteractive.materialcalendarview.MaterialCalendarView&gt;
  
              &lt;android.support.v7.widget.Toolbar
                  android:id="@+id/toolbar"
                  android:layout_width="match_parent"
                  android:layout_height="?attr/actionBarSize"
                  app:layout_collapseMode="pin"
                  android:background="@color/primary_color"
                  android:titleTextColor="@color/text_color"
                  android:minHeight="?attr/actionBarSize"
                  app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
                  app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"&gt;
  
              &lt;TextView
                  android:layout_width="wrap_content"
                  android:layout_height="wrap_content"
                  android:id="@+id/nickname_profile"
                  android:text="@string/nickname"
                  android:textColor="@color/text_color"
                  android:textSize="24sp"
                  android:layout_gravity="bottom|center"
                  android:layout_marginBottom="20dp"
                  android:layout_marginRight="40dp"
                  /&gt;
              &lt;/android.support.v7.widget.Toolbar&gt;
          &lt;/android.support.design.widget.CollapsingToolbarLayout&gt;
      &lt;/android.support.design.widget.AppBarLayout&gt;
  
              &lt;FrameLayout
                  android:layout_width="match_parent"
                  android:layout_height="match_parent"
                  android:id="@+id/general_fragment"
                  app:layout_behavior="@string/appbar_scrolling_view_behavior"&gt;
  
              &lt;/FrameLayout&gt;
  &lt;/android.support.design.widget.CoordinatorLayout&gt;
  </code></pre>
  
  <p>And second question: How can I open toolbar only on click without scroll?</p>
