Android: RecyclerView layout problem when list goes off the screen

I have an activity where a test (questions with their corresponding possible answers on each fragment) is displayed.
The question is displayed and immediately below the possible answers are displayed with a RecyclerView.
If the question is short and the answers fit on the screen no problem is found, but the problem appears as soon as the question is longer and the RecyclerViews answers goes off the screen.
The issue apparently is RecyclerView's height is not properly calculated and it takes as its height the remaining space between the question bottom and the screen bottom, so if you scroll down you get a cut RecyclerView and only scrolling again inside of it fixes partially the problem.
This is my layout where you can see the RecyclerView:
<layout xmlns:android="http://schemas.android.com/apk/res/android"

RecyclerView rv = tBinding.rv;
rv.setLayoutManager(llm);
RVAdapter_Test_QuestionAnswers adapter =
new RVAdapter_Test_QuestionAnswers(pageNumber, test, tBinding, Enum.CallingActivity.Test);
rv.setAdapter(adapter);

RecyclerView scrolling very slow with NestedScrollView

I have a RecyclerView with a NestedScrollView and the recycler view scrolling is very very slow. Why is this happening, and how can I fix this?
After googleing and searching in Stack Overflow, i got this solution:
mMyRecyclerView.setNestedScrollingEnabled(false);
But it does not improve the scroll speed in my case, please help.

This is my app on google play store, for your reference.

try to use this when you call your Linear layout manager
recyclerView.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false){
#Override
public boolean canScrollVertically() {
return false;
}
});

I am not sure but try RecyclerView height match_parent to wrap_content

Gif with my problem. Green boxes scrolled but i want to stop this green boxes scrolling

When you have two recycler view in a view and you want them to use all the space, you need to use NestedScrollView.
Your code will be the following:
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#323642"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<RelativeLayout
android:id="#+id/firstText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:paddingLeft="10dp">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="What you learn today?"
android:textColor="#color/colorWhite"
android:textStyle="bold" />
</RelativeLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/catBoxes"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/firstText"
android:layout_marginTop="5dp"
android:paddingLeft="5dp"
android:paddingRight="5dp" />
<RelativeLayout
android:id="#+id/secondText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/catBoxes"
android:paddingLeft="10dp">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Recommended for you"
android:textColor="#color/colorWhite"
android:textStyle="bold" />
</RelativeLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/catMenu"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/secondText"
android:layout_marginTop="5dp"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</RelativeLayout>
</android.support.v4.widget.NestedScrollView>
And in your code, use this in both recycler view:
LayoutManager layoutManager = new LinearLayoutManager(this);
layoutManager.setAutoMeasureEnabled(true);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setNestedScrollingEnabled(false);

Android SwipeToRefresh - Confilct with RecyclerView when swiping down

So I have a fragment with 2 RecyclerView lists. I want to swipe fragment to refresh those lists but when I scroll one of those lists to see hidden elements SwipeToRefresh refreshes those lists. How to prevent it from that?
Here is my XML layout:

android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.CoordinatorLayout
android:id="#+id/main_fragment_coordinator_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="2">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_weight="1">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="4dp"
android:textSize="18sp"
android:textColor="#color/primary_dark"
android:text="Najpopularniejsze przepisy" />
<android.support.v7.widget.RecyclerView
android:id="#+id/top_recipes_recycler_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbars="vertical" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_weight="1">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="4dp"
android:textSize="18sp"
android:textColor="#color/primary_dark"
android:text="Najnowsze przepisy" />
<android.support.v7.widget.RecyclerView
android:id="#+id/latest_recipes_recycler_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbars="vertical" />
</LinearLayout>
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>
</android.support.v4.widget.SwipeRefreshLayout>
</FrameLayout>
Any ideas?

You can consume the swipe down event in RecycleView when it can scroll up.
Just custom the RecycleView and intercept the event when you need.
