ScrollView inside RecyclerView won't scroll

Question

I want to make a LinearLayout (to which I'm adding items dynamically) scrollable inside a scrollable RecyclerView. On startup, I can see a little scrollbar initially (indicating it's a scrollable view, fades in seconds). Tried appCompat NestedScrollView as well as enabling nestedScrollingEnabled, with no success. How can I make the LinearLayout scrollable inside the RecyclerView?

<FrameLayout 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">
  <ScrollView
      android:layout_width="wrap_content"
      android:layout_height="300dp"
      android:fillViewport="true"
      android:nestedScrollingEnabled="true">
      <LinearLayout
          android:id="@+id/playerlist_linear"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:gravity="left|center_vertical"
          android:layout_marginLeft="10dp"
          android:layout_marginRight="10dp"
          android:layout_marginTop="5dp"
          android:layout_marginBottom="7dp"
          android:orientation="vertical">
      </LinearLayout>
  </ScrollView>

</FrameLayout>

RecyclerView code

<android.support.v7.widget.RecyclerView
    android:id="@+id/messagesListView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom"
    android:layout_weight="1"
    android:nestedScrollingEnabled="false"/>

UPDATE: I found out that scrolling does indeed work, but only if I spam the mouse or tap really fast inside the scrollview. It kind of gets focused and allows scrolling as long as mouse is held down. Really strange.

Add your RecylerView layout code... – rafsanahmad007 Jan 27 '18 at 15:05 — rafsanahmad007, Jan 27 '18 at 15:05

Try disabling the touch of recycler view when scrollview is being touched.

ScrollView scrollView = (ScrollView)findViewById(R.id.scrollView1);
scrollView.setOnTouchListener(new View.OnTouchListener() {
                @Override
                public boolean onTouch(View view, MotionEvent motionEvent) {
                     // Disallow the touch request for parent scroll on touch of child view
                    view.getParent().requestDisallowInterceptTouchEvent(false);
                    return true;
                }
            });

It prevents the RecyclerView from scrolling when the ScrollView is touched. But the `ScrollView` itself still won't scroll. – Nicolás de Ory Jan 27 '18 at 17:34
I guess you have to return `false` from `onTouch` – Droidman Jan 28 '18 at 01:46
Maybe. That would explain why I had to do `view.onTouch(motionEvent)`. – Nicolás de Ory Jan 29 '18 at 14:38

I solved it by adding a line to rafsanahmad007's solution:

    ScrollView scrollView = (ScrollView)findViewById(R.id.scrollView1);
    scrollView.setOnTouchListener(new View.OnTouchListener() {
                    @Override
                    public boolean onTouch(View view, MotionEvent motionEvent) {
                         // Disallow the touch request for parent scroll on touch of child view

                   view.getParent().requestDisallowInterceptTouchEvent(false);
                   view.onTouch(motionEvent);
                        return true;
                    }
                });

I'm not sure that's how View.onTouch is called on Java, as I'm developing with Xamarin.Android (C#). It should be pretty similar.

I finally found an another way how the ScrollView can be scrolled inside RecyclerView viewHolder. I originally posted my answer here, so you can look up my answer for how I can enabled the scroll of ScrollView inside RecyclerView. Hope this will help on someone who look up another answer.

But I also want to answer from the OP's question why there is a little scrollbar on the ScrollView. You can hide the scrollbar by adding android:scrollbars="none" in your ScrollView tag in xml layout and also remove android:nestedScrollingEnabled="true" because it is no use in this case.

<ScrollView
    android:layout_width="wrap_content"
    android:layout_height="300dp"
    android:fillViewport="true"
    android:scrollbars="none">
    <LinearLayout
        android:id="@+id/playerlist_linear"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="left|center_vertical"
        android:layout_marginLeft="10dp"
        android:layout_marginRight="10dp"
        android:layout_marginTop="5dp"
        android:layout_marginBottom="7dp"
        android:orientation="vertical">
    </LinearLayout>
</ScrollView>
