WebView ile kullanmak için NestedScrollView'a bir alternatif var mı?

Question

Bir NestedScrollView içinde bir WebView kullanırken, birkaç sorun vardır. Savaştığım ana şey, aşağı doğru ilerlerken daha fazla içerik yükleyen sitelerin iyi çalışmadığı, örneğin vimeo.com. Ayrıca, aynı sebepten dolayı, LAYER_TYPE_HARDWARE görünümüne ayarlanmadı, temelde yükseklik nedeniyle çöküyor. Yani, kullanıcı WebView içinde gezinirken araç çubuğunu daraltmak için CoordinatorLayout kullanmak istiyorsam NestedScrollView'a bir alternatif var mı?

Kodum aşağıda. Sorunu yeniden oluşturmak için sadece vimeo.com'u yükleyin ve aşağı kaydırın.

     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.menu_scrolling, menu); 
     return true; 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     // Handle action bar item clicks here. The action bar will 
     // automatically handle clicks on the Home/Up button, so long 
     // as you specify a parent activity in AndroidManifest.xml. 
     int id = item.getItemId(); 

     //noinspection SimplifiableIfStatement 
     if (id == R.id.action_settings) { 
      return true; 
     } 
     return super.onOptionsItemSelected(item); 
    } 
} 

DÜZENLEME: Zaten etrafında kaydırma denedim, söz unuttum bir FrameLayout, LinearLayout, RelativeLayout vb ben Ayrıca boyutları belirli bir sayıya ayarlamayı denedi.

i referred gibi, sen gibi android:descendantFocusability="blocksDescendants" ile LinearLayout eklemeyi denemelisiniz:

<android.support.v4.widget.NestedScrollView 
     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" 
     app:layout_behavior="@string/appbar_scrolling_view_behavior" 
     tools:context="com.webviewnestedscroll.ScrollingActivity" 
     tools:showIn="@layout/activity_scrolling"> 

    <LinearLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:orientation="vertical" 
     android:descendantFocusability="blocksDescendants" > 

     <WebView 
      android:id="@+id/webview" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent"></WebView> 

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

Mayıs size yardımcı olacak. Teşekkürler.
