How to disable RecyclerView scrolling to make the layout listen its ScrollView parent?

Question

I'm trying to put a RecyclerView, inside a ScrollView. But the ScrollView doesn't scrolls and the RecyclerView does but I don't want it to... What can I do?

I tried with this class https://stackoverflow.com/a/30222721/4864104 and in fact the RecyclerView doesn't scroll anymore, but neither does the ScrollView.

Any help to make the ScrollView work even with the disabled RecyclerView? Thanks in advance.

This is my layout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:fab="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="jahirfiquitiva.projects.activities.DeveloperActivity">

<include
    android:id="@+id/toolbar"
    layout="@layout/toolbar" />

<ScrollView
    android:id="@+id/osv"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@id/toolbar"
    android:fillViewport="true"
    android:gravity="center"
    android:overScrollMode="never">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:padding="10dp">

        <ImageView
            android:id="@+id/photoJahir"
            android:layout_width="144dp"
            android:layout_height="144dp"
            android:layout_gravity="center"
            android:gravity="center" />

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:lineSpacingMultiplier="1.2"
            android:paddingBottom="@dimen/lists_padding"
            android:paddingTop="@dimen/lists_padding"
            android:text="@string/developer_bio"
            android:textSize="@dimen/abc_text_size_subtitle_material_toolbar" />

        <View
            android:layout_width="match_parent"
            android:layout_height="@dimen/dividers_about_section"
            android:alpha="0.3"
            android:background="@color/primary" />

        <RecyclerView
            android:id="@+id/buttonsGrid"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:paddingBottom="@dimen/lists_padding"
            android:paddingTop="@dimen/lists_padding" />

        <View
            android:layout_width="match_parent"
            android:layout_height="@dimen/dividers_about_section"
            android:alpha="0.3"
            android:background="@color/primary" />

        <View
            android:layout_width="match_parent"
            android:layout_height="72dp" />

    </LinearLayout>

</ScrollView>

Solution

You could easily achieve it by changing your scroll view into a NestedScrollView and setting recyclerView.setNestedScrollingEnabled(false) Has the highest performance and No need to override the layout manager.
