  WebView in CoordinatorLayout with CollapsingToolbarLayout
  
  I'd like to add a WebView in a CoordinatorLayout, having CollapsingToolbarLayout in AppBarLayout.
  The problem is that WebView shrinks in height and doesn't fill the space below the toolbar, making it not usable. 
  I tried also to use WebView as child of NestedScrollView: initially it doesn't work (it shrinks my WebView in height), but scrolling my shrinked WebView makes it fill viewport.
  Here is the layout I used:
  <?xml version="1.0" encoding="utf-8"?>
  <android.support.design.widget.CoordinatorLayout
      android:id="@+id/main_content"
      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"
      android:fitsSystemWindows="true">
  
      <android.support.design.widget.AppBarLayout
          android:id="@+id/appbar"
          android:layout_width="match_parent"
          android:layout_height="256dp"
          android:fitsSystemWindows="true"
          android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
  
          <android.support.design.widget.CollapsingToolbarLayout
              android:id="@+id/collapsing_toolbar"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:fitsSystemWindows="true"
              app:contentScrim="?attr/colorPrimary"
              app:expandedTitleMarginEnd="64dp"
              app:expandedTitleMarginStart="48dp"
              app:layout_scrollFlags="scroll|exitUntilCollapsed">
  
              <ImageView
                  android:id="@+id/backdrop"
                  android:layout_width="match_parent"
                  android:layout_height="match_parent"
                  android:fitsSystemWindows="true"
                  android:scaleType="centerCrop"
                  app:layout_collapseMode="parallax" />
  
              <android.support.v7.widget.Toolbar
                  android:id="@+id/toolbar"
                  android:layout_width="match_parent"
                  android:layout_height="?attr/actionBarSize"
                  app:layout_collapseMode="pin"
                  app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />
  
          </android.support.design.widget.CollapsingToolbarLayout>
  
      </android.support.design.widget.AppBarLayout>
  
      <android.support.v4.widget.NestedScrollView
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          app:layout_behavior="@string/appbar_scrolling_view_behavior">
  
          <WebView
              android:id="@+id/article"
              android:layout_width="match_parent"
              android:layout_height="match_parent" />
      </android.support.v4.widget.NestedScrollView>
  </android.support.design.widget.CoordinatorLayout>
  
  A:
  
  You can use android:fillViewport="true" for NestedScrollView and layout_height="wrap_content" for WebView

  The bug is now fixed in the latest (22.2.1) design support library.
