La vista de Recycler no se desplaza correctamente después de implementar el desplazamiento para actualizar el diseño.

Antes de la implementación de la vista Desactivar para actualizar, la vista del reciclador funcionaba sin problemas, pero no siempre que intento desplazar la vista del reciclador hacia abajo el golpe para actualizar interfiere e impide el movimiento de desplazamiento.

Aquí está la captura de pantalla del problema:

• ¿Cómo activar swiperefreshlayout en android?
• SwipeRefreshLayout obstruye el desplazamiento de recycleview en el momento de desplazarse hacia arriba
• Error de Android inflar clase SwipeRefreshLayout
• SwipeRefreshLayout sin animación en la creación de fragmentos
• Cómo añadir una sugerencia de texto a Android SwipeRefreshLayout

(Observe que el desplazamiento para actualizar el diseño aparece mientras la vista del reciclador se desplaza hacia abajo)

Aquí está mi fragmento de diseño:

También he implementado el diseño del coordinador en el diseño de la actividad. Aquí está el código:

 <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"> <android.support.design.widget.AppBarLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"> <include layout="@layout/toolbar" android:id="@+id/toolbar"/> <android.support.design.widget.TabLayout android:id="@+id/sliding_tabs" android:layout_width="match_parent" android:layout_height="wrap_content" app:tabMode="scrollable" app:tabGravity="fill" /> </android.support.design.widget.AppBarLayout> <android.support.v4.view.ViewPager android:id="@+id/viewPager" android:layout_width="match_parent" android:layout_height="match_parent" app:layout_behavior="@string/appbar_scrolling_view_behavior" /> </android.support.design.widget.CoordinatorLayout> 

¿Puede ayudarme a resolver este problema? Será de gran ayuda. Gracias por adelantado.
