How to get a whole screen in an activity to scroll when a scrollable recyclerView imakes up only half of the phone screen

I want my whole screen to scroll but only my recycler will scroll at the moment. This occurs despite all elements being placed in a linear layout inside a Scroll View.
Any ideas where the error is? Here's the relevant code.
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 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=".NoodleDetailActivity">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:id="#+id/noodleImage"
android:layout_width="match_parent"
android:layout_height="200dp"
android:adjustViewBounds="false"
android:scaleType="centerCrop"
app:srcCompat="#mipmap/ic_launcher" />
<TextView
android:id="#+id/description"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/border_bottom"
android:fontFamily="sans-serif-smallcaps"
android:hapticFeedbackEnabled="false"
android:padding="30dp"
android:text="TextView"
android:textSize="18sp" />
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/extras_recycler"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="0dp"
android:background="#F2F2F2"
android:padding="0dp" />
</LinearLayout>
</ScrollView>
</androidx.constraintlayout.widget.ConstraintLayout>
This is what it looks visually.

Found out: it seems best practice is to set the recyclerView to be the whole layout and make it contain multiple view types.
I won't be using a nested scroll view.

How to Control Visibility of items in a Linear Layout in my App?

I have a Vertical linear layout with 2 item. One is a is a customview which is extended from a framelayout and the 2nd one is a textview with a drawable as background. The visibility have to be controlled dynamically from gone to visible.
The issue is that when i change the visibility of the item from gone to visible the order is not coming as i intended. The the second item is below the customview. I want it to come as the 2nd item, below the customview
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:textureview="http://schemas.android.com/apk/res-auto">
<LinearLayout
android:id="#+id/comment_holder"

android:layout_height="wrap_content">

<com.custom_views.PlaybackTextureView
android:visibility="gone"
android:id="#+id/playback_texture_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
textureview:isAuthorMode="true"/>
</com.custom_views.CircularFrameLayout>
<LinearLayout
android:visibility="gone"
android:id="#+id/c_holder"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingTop="8dp"
android:paddingBottom="16dp"
android:paddingStart="4dp"
android:paddingEnd="4dp"
android:background="#drawable/chat_bubble_top_arrow_orange"
android:orientation="vertical">
<TextView
android:id="#+id/video_comment_user_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="12sp"
android:textColor="#color/black_50"
android:fontFamily="sans-serif" />
</LinearLayout>
</LinearLayout>
</FrameLayout>
NOTE: I tried adding weight to the custom layout as 1. But it still didnt help.

How can I use listview inside a scrollview in android?

This is the image I want in my application:
I tried using listview inside a scrollview but the problem is that I am not able to stretch listview to its full size. Can anyone tell me how can I do this??

You can use your recyclerview as below example :
<android.support.v4.widget.NestedScrollView
android:id="#+id/nestedScroll"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
app:layout_collapseMode="pin">
<!-- Some views-->
</LinearLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_bubhub_comment_list"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
You can use below properties in recyclerview if you need both layout to scroll. Otherwise it would work as single scrolling view. These properties allows Recyclerview to scroll inside NestedScrollView
app:layoutManager="android.support.v7.widget.LinearLayoutManager"
app:layout_behavior="#string/appbar_scrolling_view_behavior"

Android: Swipe to refresh gets stuck on a recycler view with view pager

Here is my XML code
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/flipper">
<android.support.v4.widget.SwipeRefreshLayout
android:id="#+id/refreshLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/headerLayout"
android:background="#color/background_color"
android:visibility="visible">
<android.support.v7.widget.RecyclerView
android:id="#+id/list_appointment"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</android.support.v4.widget.SwipeRefreshLayout>
<RelativeLayout
android:id="#+id/emptyView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:visibility="gone">
<ImageView
android:id="#+id/empty"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:src="#drawable/ic_event_note"
android:textAppearance="?android:textAppearanceMedium" />
</RelativeLayout>
</FrameLayout>
The RecyclerViews adapter supports two types of views one is CardView and another is ViewPager.
When I swipe to refresh, the circular refresh icon freezes on top of the ViewPager.onrefresh method is called after I tap the refresh icon again.Is there any fix to this issue?

Any Help is really appreciated and thanks in advance...

In you layout there is textview and after that listview so why you not used expandable listVIew.It will help you in your problem.
Here is example of Expandable listview

An simple workaround is to
Remove ScrollView
Set height of all ListView to 0
Set layout_weight property of all child to 1

To overcome, try re-factoring your UI to not include multiple scrollable objects inside of another scrollable object. This will not be reliable and will produce unexpected results (as you have found).
As the100rabh said, this is generally bad design. Normally an application will present a list of some sort to a user. Four lists for a screen that is 2-5 (~10 for tablets) inches is three too many.

please set your listview as a non scrolling container By using
ls_edu.setScrollContainer(false);
it may help to scroll the list view.
