android - WebView in CoordinatorLayout with CollapsingToolbarLayout -


i'd add webview in coordinatorlayout, having collapsingtoolbarlayout in appbarlayout. problem webview shrinks in height , doesn't fill space below toolbar, making not usable. tried use webview child of nestedscrollview: doesn't work (it shrinks webview in height), scrolling shrinked webview makes fill viewport.

here layout 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>

you can use android:fillviewport="true" nestedscrollview , layout_height="wrap_content" webview
