Android recycler view не прокручивает

Question

У меня есть деятельность, которая отображает AppToolbar рядом с RecyclerView, который находится ниже Toolbar. Каждая строка RecyclerView - это CardView. Моя проблема в том, что RecyclerView не прокручивается вообще. Кажется, что он не получает никаких обратных вызовов жестов.

Вот мой основной макет XML:

<?xml version="1.0" encoding="utf-8"?> 
<android.support.design.widget.CoordinatorLayout 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:background="@color/colorActivityBackground" 
    tools:context=".MainActivity"> 

     <android.support.v7.widget.RecyclerView 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      android:id="@+id/rv" 
      android:scrollbarAlwaysDrawVerticalTrack="true" 
      android:scrollbars="vertical" 
      android:fadeScrollbars="true" 
      app:layout_behavior="@string/appbar_scrolling_view_behavior"/> 


    <include layout="@layout/tool_bar" /> 

    <include layout="@layout/nav_drawer_layout" /> 

    <android.support.design.widget.FloatingActionButton 
     android:id="@+id/fab" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_margin="@dimen/fab_margin" 
     android:src="@drawable/ic_add" 
     app:layout_anchor="@id/rv" 
     app:layout_anchorGravity="bottom|end" /> 

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

Edit: Вот панель инструментов Код:

<?xml version="1.0" encoding="utf-8"?> 
<android.support.design.widget.AppBarLayout android:id="@+id/app_bar" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:fitsSystemWindows="false" 
    android:theme="@style/AppTheme.AppBarOverlay" 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto"> 

    <android.support.v7.widget.Toolbar 
     android:id="@+id/toolbar" 
     android:layout_width="match_parent" 
     android:layout_height="?attr/actionBarSize" 
     android:elevation="4dp" 
     android:theme="@style/AppTheme.AppBarOverlay" 
     app:layout_collapseMode="pin" 
     app:popupTheme="@style/AppTheme.PopupOverlay" /> 
</android.support.design.widget.AppBarLayout> 

Вот и мой нав ящик расположение:

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:layout_marginTop="?attr/actionBarSize"> 

    <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" 
     android:id="@+id/drawer_layout" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent"> 
     <!-- The main content view --> 
     <FrameLayout 
      android:id="@+id/content_frame" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" /> 
     <!-- The navigation drawer --> 
     <android.support.v7.widget.RecyclerView 
      android:id="@+id/right_drawer" 
      android:layout_width="240dp" 
      android:layout_height="match_parent" 
      android:layout_gravity="start" 
      android:choiceMode="singleChoice" 
      android:divider="@android:color/transparent" 
      android:dividerHeight="0dp" 
      android:background="#99ccff" /> 

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

Answer 1

I think your layout is wrong. Make the following changes in nav drawer layout. 

<LinearLayout 
      android:id="@+id/content_frame" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      android:orientation="vertical" > 
<include layout="@layout/tool_bar" /> 

<android.support.v7.widget.RecyclerView 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      android:id="@+id/rv" 
      android:scrollbarAlwaysDrawVerticalTrack="true" 
      android:scrollbars="vertical" 
      android:fadeScrollbars="true" 
      app:layout_behavior="@string/appbar_scrolling_view_behavior"/> 
</LinearLayout> 

And`kindly remove the recycler view from main layout.
