Scrollbar not showing in RecyclerView

Question

I've got a RecyclerView and would like to have scrollbar showing, when it covers more than one page.

I get no scrollbar at all. Any idea?

My layout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <CheckBox
        android:id="@+id/cl_only_empty"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:elevation="5dp"
        android:text="@string/cl_only_empty"
        android:textColor="@color/white" />

    <android.support.v7.widget.RecyclerView
        android:id="@+id/callsList"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scrollbars="vertical" />

</LinearLayout>

Answer 1

If you are fine to set ScrollBar programmatically, then you can use ContextThemeWrapper. First you need to define styling in Style.xml file:

<style name="ScrollbarRecyclerView" parent="android:Widget">
    <item name="android:scrollbars">vertical</item>
</style>

And then apply styling when you initialize your RecylerView:

RecyclerView recyclerView = new RecyclerView(new ContextThemeWrapper(context, R.style.ScrollbarRecyclerView));

Answer 2

use recyclerView as below in xml layout

   <android.support.v7.widget.RecyclerView
    android:id="@+id/recyclerView"
    android:scrollbars="vertical"
    android:fadeScrollbars="true"
    android:layout_width="match_parent"
    android:layout_height="match_parent"  />

and add below code for scrollview in java, it will be okay

 RecyclerView recyclerView = (RecyclerView) view.findViewById(R.id.recyclerView);
 recyclerView.setLayoutManager(new LinearLayoutManager(getActivity(), LinearLayoutManager.VERTICAL, false));
 recyclerView.setHasFixedSize(true);

Answer 3

Add the code to Recycler view xml to make scroll bar visible.

<android.support.v7.widget.RecyclerView
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:fadeScrollbars="false"
 android:scrollbars="vertical"
 android:scrollbarSize="@dimen/_2sdp"
 android:scrollbarThumbVertical="@color/white"/>

Answer 4

Use android:scrollbars attribute "vertical" and android:scrollbarThumbVertical attribute to set the color and android:scrollbarSize attribute to specifiy size:

<android.support.v7.widget.RecyclerView
        android:id="@+id/document_listview"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="3dp"
        android:layout_marginTop="3dp"
        android:scrollbars="vertical"
        android:scrollbarThumbVertical="@android:color/darker_gray"
        android:scrollbarSize="5dp"
        android:background="@color/activity_bg"
        android:dividerHeight="4dp" />

Answer 5

Scroller can be set to recyclerview on multiple ways. 1st you can simply add scrollbar in xml and set its property android:fadeScrollbars="false" to always show it.

<android.support.v7.widget.RecyclerView
        android:id="@+id/recyclerViewMachine"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
         android:scrollbars="vertical"
        android:fadeScrollbars="false"
        android:scrollbarThumbVertical="@android:color/darker_gray"
        android:scrollbarSize="5dp"
        android:scrollbarStyle="outsideOverlay"/>

Or you can make a style theme and use it programitically when initializing recyclerview

  <style name="ScrollbarRecyclerView" parent="android:Widget">
        <item name="android:scrollbars">vertical</item>
    </style>

RecyclerView recyclerView = new RecyclerView(new ContextThemeWrapper(context, R.style.ScrollbarRecyclerView));
