在 RecyclerView 中禁用滚动

Posted 2023-04-19

【中文标题】在 RecyclerView 中禁用滚动

【英文标题】：Disable Scrolling in RecyclerView

【发布时间】：2020-11-10 13:31:01

【问题描述】：

在代码中，RecyclerView 在 ViewPager 中。 当 RecyclerView 大于 ViewPager 时，我想在 ViewPager 中启用滚动。 在recyclerView中展开所有列表，如何只能滚动viewPager？ 我做了nestedScrollingEnabled="false"，但没有工作，也不是好方法。

这是我的代码

fragment.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_
android:layout_
android:orientation="vertical"
tools:context="StoreFragment">

<LinearLayout
    android:layout_
    android:layout_
    android:orientation="vertical"
    android:layout_marginTop="20dp"
    android:layout_marginBottom="10dp"
    android:layout_marginLeft="20dp"
    android:layout_marginRight="20dp">
    //...
</LinearLayout>

<LinearLayout
    android:layout_
    android:layout_
    android:gravity="center"
    android:background="@color/colorGray">
    //...
</LinearLayout>

<RelativeLayout
    android:layout_
    android:layout_
    android:layout_marginTop="20dp"
    android:layout_marginBottom="10dp"
    android:layout_marginLeft="20dp"
    android:layout_marginRight="20dp">
    //...
    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/recyclerViewMenu"
        android:layout_
        android:layout_
        android:layout_below="@+id/textMenuMain"
        android:nestedScrollingEnabled="false"/>
</RelativeLayout>

【参考方案1】：

试试这个

 LinearLayoutManager layoutManager = new LinearLayoutManager(context) 
 @Override
 public boolean canScrollVertically() 
  return false;
 
;

recyclerView.setLayoutManager(layoutManager);
