与滚动recyclerview

Question

折叠标题图片我有一个XML布局是这样的：

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
xmlns:app="http://schemas.android.com/apk/res-auto" 
android:id="@+id/activity_main" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
tools:context="realup.ir.teacher.MainActivity"> 

<android.support.design.widget.CoordinatorLayout 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:id="@+id/header"> 

    <android.support.design.widget.AppBarLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:id="@+id/app_bar_head"> 
     <android.support.design.widget.CollapsingToolbarLayout 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      app:layout_scrollFlags="scroll|enterAlways" 
      android:id="@+id/collapse_toolbar"> 

      <ImageView 
       android:layout_width="match_parent" 
       android:layout_height="wrap_content" 
       android:adjustViewBounds="true" 
       android:scaleType="centerCrop" 
       android:src="@drawable/realup" 
       android:id="@+id/header_image"/> 


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

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

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



<android.support.v7.widget.RecyclerView 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:id="@+id/recycle" 
    android:layout_below="@+id/header"/> 

</RelativeLayout> 

正如你所看到的，我有一个recyclerview，我希望在recyclerview被向下滚动到，图像视图是随着滚动回收站查看崩溃。你可以帮我吗？预先感谢您:)

你RecyclerView应在Coordinatorlayout进行动画和使用NestedScrollView作为家长的您RecyclerView：

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
xmlns:app="http://schemas.android.com/apk/res-auto" 
android:id="@+id/activity_main" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
tools:context="realup.ir.teacher.MainActivity"> 

<android.support.design.widget.CoordinatorLayout 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:id="@+id/header"> 

    <android.support.design.widget.AppBarLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:id="@+id/app_bar_head"> 
     <android.support.design.widget.CollapsingToolbarLayout 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      app:layout_scrollFlags="scroll|enterAlways" 
      android:id="@+id/collapse_toolbar"> 

      <ImageView 
       android:layout_width="match_parent" 
       android:layout_height="wrap_content" 
       android:adjustViewBounds="true" 
       android:scaleType="centerCrop" 
       android:src="@drawable/realup" 
       android:id="@+id/header_image"/> 


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

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

    <android.support.v4.widget.NestedScrollView 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      app:layout_behavior="@string/appbar_scrolling_view_behavior"/> 

     <android.support.v7.widget.RecyclerView 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:id="@+id/recycle"/> 

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

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

为了得到一个平滑滚动effet在代码中添加：

RecyclerView recyclerView = (RecyclerView)findViewById(R.id.recycle); 
recyclerView.setNestedScrollingEnabled(false); 

希望这会有所帮助。

对不起，我的英语。

以CoordinatorLayout作为父级布局，并将RecyclerView放入FrameLayout;

<android.support.design.widget.CoordinatorLayout 
    android:id="@+id/coordinator" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 

    <android.support.design.widget.AppBarLayout 
     android:id="@+id/appbar" 
     android:background="#e7e5e5" 
     android:layout_marginLeft="-20dp" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content"> 

     <android.support.design.widget.CollapsingToolbarLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     app:layout_scrollFlags="scroll|enterAlways" 
     android:id="@+id/collapse_toolbar"> 

     <ImageView 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:adjustViewBounds="true" 
      android:scaleType="centerCrop" 
      android:src="@drawable/realup" 
      android:id="@+id/header_image"/> 


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

    <FrameLayout 
     android:id="@+id/dashboard_content" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     app:layout_behavior="@string/appbar_scrolling_view_behavior"> 

     <android.support.v7.widget.RecyclerView 
      android:id="@+id/task_list" 
      android:scrollbars="vertical" 
      android:paddingBottom="85dp" 
      android:layout_marginLeft="10dp" 
      android:layout_marginRight="10dp" 
      app:layout_behavior="@string/appbar_scrolling_view_behavior" 
      android:layout_marginTop="10dp" 
      android:clipToPadding="false" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content"> 

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

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