RecyclerView that does not scroll and shows all items

I have a RecyclerView (and some other views) in a ScrollView. Currently the RecyclerView is laid out as very small (it shows 2 items out of 5 that it contains) and it scrolls independently of the ScrollView, which is obviously not great UX. I would like to get the RecyclerView to not scroll and to extend so that all its items are visible.

(I know it's stupid to use a RecyclerView in this case. I'm only doing this because somewhere else in the app I need a normal RecyclerView with scrolling etc. but the same kind of content, and I don't want to duplicate code).

It’s pretty simple, simply set the RecyclerView’s height to wrap_content.

You might also benefit from disabling nested scrolling on the recycler view, like so:

RecyclerView recycler = (RecyclerView) findViewById(R.id.recycler);
recycler.setNestedScrollingEnabled(false);

The solution of setNestedScrollingEnabled(false) isn't as full as it should: you need to use NestedScrollView instead of ScrollViewfocusableInTouchMode="true" to the child of the NestedScrollView .

If you insist on using ScrollView, you should also set minHeight to the RecyclerView, and also set overScrollMode="never" . In this case, it still isn't a good solution because the minHeight might not be enough in some cases

Other alternative solutions that you should consider:

1. Replace the ScrollView&RecyclerView with a single RecyclerView, which has views with additional view type for what you had in the ScrollView

2. Use GridLayout or another layout instead.

Maybe it is not completely clear at first sight what to do with all these answers. I just tried them and the working one is:

<android.support.v4.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:id="@+id/person_properties"
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
...
        <android.support.v7.widget.RecyclerView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:overScrollMode="never" />
    </LinearLayout>
</android.support.v4.widget.NestedScrollView>

No need to change anything programmatically.

In your activity.xml file

<androidx.core.widget.NestedScrollView 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="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=".ActivityName">
        
    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/RecyclerView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:nestedScrollingEnabled="false">
        
     </androidx.recyclerview.widget.RecyclerView>
        
</androidx.core.widget.NestedScrollView>

In RecyclerView use android:nestedSrollingEnabled="false" and use NestedScrollView as a parent Scroll View.

If you are using RecyclerView inside ScrollView then Replace ScrollView with NestedScrollView and enable the nested scrolling

android:nestedScrollingEnabled="false"

This Solved my problem

An easy way is to use in your Custom Adapter, inside the onBindViewHolder method this line: holder.setIsRecyclable(false);

I realised that I use BottomNavigationView which blocked my recycler view from displaying the last item. I fixed it by adding paddingBottom to it:

    <androidx.recyclerview.widget.RecyclerView
                android:id="@+id/recipient_list"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:paddingBottom="70dp"
                app:layout_constraintTop_toBottomOf="@id/view"
                />

Also try to play with:

android:overScrollMode

You should replace your scrollView for androidx.core.widget.NestedScrollView with matchparent, its simple and work fine.

Following is the code for disabling scroll in the recycler-view, and showing all the items in your layout. It might work:

public class NoScrollRecycler extends RecyclerView {

    public NoScrollRecycler(Context context){
        super(context);
    }

    public NoScrollRecycler(Context context, AttributeSet attrs){
        super(context, attrs);
    }

    public NoScrollRecycler(Context context, AttributeSet attrs, int style){
        super(context, attrs, style);
    }

    @Override
    public boolean dispatchTouchEvent(MotionEvent ev){

        //Ignore scroll events.
        if(ev.getAction() == MotionEvent.ACTION_MOVE)
            return true;

        //Dispatch event for non-scroll actions, namely clicks!
        return super.dispatchTouchEvent(ev);
    }
}

use like this way:

<com.example.custom.NoScrollRecycler
    android:id="@+id/recyclerView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/color_white"/>

probably parent of recyclerView is a constraintLayout changed it to RelativeLayout
