当我们尝试滚动时，即使到达列表的末尾(顶部或底部)，如何更改recyclerview上的灰色或白色覆盖层.我找不到可以用来做的属性名称.

How can I change the grey or white overlay that comes on recyclerview when we try to scroll even when we reached the end(top or bottom) of list. I am not able to find the property name to which I can use to do it.

推荐答案

RecyclerView从主题的colorPrimary中获取阴影.

The RecyclerView take the shadow from the colorPrimary of your Theme.

您需要为RecyclerView创建新主题，然后将此主题应用于您的RecyclerView

You need to create new theme for RecyclerView then apply this Theme to your RecyclerView

在下面的示例中，主题colorPrimary为colorGreen，因此它将带有绿色阴影.

In below example themes colorPrimary is colorGreen so it will take green color shadow.

示例代码

<android.support.v7.widget.RecyclerView
     android:id="@+id/ha_citiesRC"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:layout_marginTop="10dp"
     android:requiresFadingEdge="vertical"
     android:theme="@style/CustomTheme"
     android:nestedScrollingEnabled="false" />

主题

 <style name="CustomTheme" parent="Theme.AppCompat.Light.DarkActionBar">

   <item name="colorPrimary">@color/colorGreen</item>
   <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
   <item name="colorAccent">@color/colorAccent</item>

 </style>
