WebView ze zwijanym paskiem narzędzi? (material design)

Question

Zajmuję się tworzeniem aplikacji na Androida z Działalnością i dwoma rodzajami fragmentów.

Typ 1: fragment ze zwijanym paskiem narzędzi i widokiem RecyclerView jako treść. (To działa). Układ:

<android.support.design.widget.CoordinatorLayout xmlns:app="http://schemas.android.com/apk/res-auto" 
    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="250dp" 
     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/header" 
       android:layout_width="match_parent" 
       android:layout_height="match_parent" 
       android:background="@drawable/indicaciones" 
       android:fitsSystemWindows="true" 
       android:scaleType="centerCrop" 
       app:layout_collapseMode="parallax" /> 


      <android.support.v7.widget.Toolbar 
       android:id="@+id/anim_toolbar" 
       android:layout_width="match_parent" 
       android:layout_height="100dp" 
       app:layout_collapseMode="pin" 
       app:popupTheme="@style/ThemeOverlay.AppCompat.Light"> 

      </android.support.v7.widget.Toolbar> 

     </android.support.design.widget.CollapsingToolbarLayout> 

    </android.support.design.widget.AppBarLayout> 

    <android.support.v7.widget.RecyclerView 
     android:id="@+id/scrollableview" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:background="@android:color/white" 
     app:layout_behavior="@string/appbar_scrolling_view_behavior" /> 

    <android.support.design.widget.FloatingActionButton 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_margin="20dp" 
     android:clickable="true" 
     android:src="@android:drawable/ic_menu_add" 
     android:visibility="gone" 
     app:layout_anchor="@+id/appbar" 
     app:layout_anchorGravity="bottom|right|end" /> 


</android.support.design.widget.CoordinatorLayout> 

Typ 2: fragment ze składanego paska i WebView jako treść. (Oto problem). Próbowałem zmieniając RecyclerView przez „WebView” i wygląda to tak:

<android.support.design.widget.CoordinatorLayout xmlns:app="http://schemas.android.com/apk/res-auto" 
    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="250dp" 
     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/header" 
       android:layout_width="match_parent" 
       android:layout_height="match_parent" 
       android:background="@drawable/indicaciones" 
       android:fitsSystemWindows="true" 
       android:scaleType="centerCrop" 
       app:layout_collapseMode="parallax" /> 


      <android.support.v7.widget.Toolbar 
       android:id="@+id/anim_toolbar" 
       android:layout_width="match_parent" 
       android:layout_height="100dp" 
       app:layout_collapseMode="pin" 
       app:popupTheme="@style/ThemeOverlay.AppCompat.Light"> 

      </android.support.v7.widget.Toolbar> 

     </android.support.design.widget.CollapsingToolbarLayout> 

    </android.support.design.widget.AppBarLayout> 

    <WebView 
     android:id="@+id/scrollableview" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:background="@android:color/white" 
     app:layout_behavior="@string/appbar_scrolling_view_behavior" /> 

    <android.support.design.widget.FloatingActionButton 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_margin="20dp" 
     android:clickable="true" 
     android:src="@android:drawable/ic_menu_add" 
     android:visibility="gone" 
     app:layout_anchor="@+id/appbar" 
     app:layout_anchorGravity="bottom|right|end" /> 


</android.support.design.widget.CoordinatorLayout> 

Problemem jest to, że WebView nie pojawia. Jakieś sugestie? Masz pomysł na osiągnięcie tego? Czy robię to w porządku?

Z góry dziękuję.

EDIT:

załadować Webview ten sposób:

String template = ... (a xml string, well formed). 
webView.getSettings().setJavaScriptEnabled(true); 
     webView.getSettings().setBuiltInZoomControls(true); 
     webView.getSettings().setDisplayZoomControls(false); 
     webView.loadDataWithBaseURL("file:///android_asset/", template, "text/html", "UTF-8", ""); 
     webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null); 
     webView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE); 
     webView.getSettings().setSupportZoom(true); 
     webView.getSettings().setRenderPriority(WebSettings.RenderPriority.HIGH); 

Próbowałem to również:

WebSettings ws = webView.getSettings(); 
    ws.setJavaScriptEnabled(true); 
    webView.loadUrl("http://www.google.com"); 

    webView.setWebViewClient(new WebViewClient() { 
     @Override 
     public boolean shouldOverrideUrlLoading(WebView view, String url) { 
      view.loadUrl(url); 
      return true; 
     } 
    }); 

Answer 1

Połóż Webview do NestedScrollView i ustawić androida: isScrollContainer: false

Tak powinno być

<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/scrollableview" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:background="@android:color/white" 
     android:isScrollContainer="false"/> 

</android.support.v4.widget.NestedScrollView> 

zamiast swojego WebView
