Question

我的RecyclerView内有两个NavigationDrawer。两者都有蓝色滚动效果。

如何在RecyclerViews中删除此效果？

我尝试将mRecyclerView.setHasFixedSize(true);更改为false，但会删除滚动效果。（这种方法的作用是什么？）

Answer 1

将此添加到您的布局：

android:overScrollMode="never"

所以：

<android.support.v7.widget.RecyclerView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:overScrollMode="never"
    android:background="#FFFFFF"
    android:scrollbars="vertical" />
