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:

{
LinearLayoutManager llm = new LinearLayoutManager(context,
LinearLayoutManager.VERTICAL, false);
RecyclerView rv = tBinding.rv;
rv.setLayoutManager(llm);
RVAdapter_Test_QuestionAnswers adapter =
new RVAdapter_Test_QuestionAnswers(pageNumber, test, tBinding, Enum.CallingActivity.Test);
rv.setAdapter(adapter);
}

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

You can use Scrollview to show scrollable calenderview.
Show below code and change as per your requirement:-
<LinearLayout
android:id="#+id/gview1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ScrollView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:fillViewport="true">
<com.prolificinteractive.materialcalendarview.MaterialCalendarView
android:id="#+id/calendarView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:mcv_arrowColor="#color/colorPrimary"
app:mcv_selectionColor="#color/colorPrimary" />
</Scrollview>
</LinearLayout>

The Parent View(ScrollView) have a separate scroll option and ListView have a separate scroll so when you try to use scroll listView that scroll option only working this case parent scroll not working.
Please try to use NestedScrollView.
NestedScrollView is just like ScrollView, but it supports acting as both a nested scrolling parent and child on both new and old versions of Android. Nested scrolling is enabled by default.
https://developer.android.com/reference/android/support/v4/widget/NestedScrollView.html
Example : https://inducesmile.com/android-tips/android-recyclerview-inside-nestedscrollview-example/
Put the ScrollView as a parent like this:
<ScrollView 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"

Change:

That is change the height of the second parent linear layout to wrap_content
