title: How to show collapsed elements in CoordinatorLayout programmatically?
body: <p>I have <code>CoordinatorLayout</code> as described in blog: <a href="http://android-developers.blogspot.ru/2015/05/android-design-support-library.html" rel="nofollow">http://android-developers.blogspot.ru/2015/05/android-design-support-library.html</a></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:layout_width="match_parent"
      android:layout_height="match_parent"&gt;
  
    &lt;android.support.v7.widget.RecyclerView
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          app:layout_behavior="@string/appbar_scrolling_view_behavior" /&gt;
  
    &lt;android.support.design.widget.AppBarLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"&gt;
       &lt;android.support.v7.widget.Toolbar
                ...
                app:layout_scrollFlags="scroll|enterAlways"&gt;
  
       &lt;TextView
                ...
                app:layout_scrollFlags="scroll|enterAlways"&gt;
     &lt;/android.support.design.widget.AppBarLayout&gt;
  &lt;/android.support.design.widget.CoordinatorLayout&gt;
  </code></pre>
  
  <p>Inside <code>AppBarLayout</code> I have <code>Toolbar</code> and <code>TextView</code> with additional status info. <code>AppBarLayout</code> can be collapsed (after scrolling). Sometimes I need to show <code>AppBarLayout</code> in order to show changed status. </p>
