How to add space below scroll view

I have wrapped an activity in an scroll view like following.
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
>
<include layout="#layout/content_form" />
</ScrollView>
I have around 15 fields in the content_form layout, the issues is that the last item in content_form layout is attached with bottom.
I need to add a margin below the scroll view, i have tried giving margin to scrollviewand the last item of content_form field, but nothing is working.
I need to know how to add margin at the bottom of page when using scroll view.

If you want the scrolling margin to be within the content, it would be best to add it to content_form. You should be able to accomplish this by either adding paddingBottom to your parent container in that layout, or layout_marginBottom on your last view aligned to the parent bottom.

This make padding under the last item in scroll view. may be good for you
<androidx.core.widget.NestedScrollView
android:layout_width="match_parent"
android:paddingBottom="80dp"
android:clipToPadding="false"
android:layout_height="match_parent">

You can either use Space or View for the purpose like
<Space
android:layout_width="100dp"
android:layout_height="match_parent"/>
Or,
<View
android:layout_width="100dp"
android:layout_height="match_parent"
android:layout_weight="1"/>

Here, you need to give padding, not margin.
Try giving padding to the ScrollView.

I've had issues with ScrollView being ill-behaved when it's direct childview is not a LinearLayout. So please try LinearLayout as direct child of your scrollView and place <include> layout inside LinearLayout.
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
... your layouts go here ...
</LinearLayout>
</ScrollView>

Android HorizontalScrollView appearing as Vertical

Hi I want to create a horizontal scrollview but it comes out as vertical. Can you help?
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="horizontal">
<ListView
android:id="#+id/household_member_list"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
</HorizontalScrollView>
Here is what appears:
Please help. Thanks.

You are using ListView inside of ScrollView, this will not work.
If you want to have horizontal ListView you need to use RecyclerView
More here:
Horizontal ListView in Android?

You can use recyclerview.
Set horizontal linear layout as layoutmanager for recyclerview to achieve horizontal scrolling

ScrollView not working inside CardView

I have already searched SO and none of the answer helped me.
Here is my layout xml:
<android.support.v7.widget.CardView
android:id="#+id/layout_building"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginTop="#dimen/_8dp"
app:layout_constraintEnd_toStartOf="#+id/scrollview_nested_fragment_container"
app:layout_constraintHorizontal_weight="1"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/views_container">
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:id="#+id/layout_building_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"/>
</ScrollView>
</android.support.v7.widget.CardView>
I'm adding child views to my LinearLayout dynamically via code. I have also tried to move the ScrollView tag to wrap CardView but still no luck. Is this a limitation of CardView or do any one know a working solution to this.

It will be better if you 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.
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
//Your CHILD Layout
</android.support.v4.widget.NestedScrollView>
FYI
You can put your CardView under ScrollView.

Okay first of all thanks to every one for helping with your valauble suggestions. The actual problems lies with the ConstraintLayout. All needs to be done is add a constraint app:layout_constraintBottom_toBottomOf="parent" to the cardview and set android:layout_height="0dp". The cardview didn't have any boundary inforced. Unlike LinearLayout and RelativeLayout which by default inforce the boundary to their child views.

set this property in ScrollView
android:fillViewport="true"
and set height of cardview to match parent or fixed

How to use two recyclerView in single activity?

I want to implement two RecyclerView with different layout in single activity. The above RecyclerView should scroll vertical and the one below should scroll horizontal. But when I run the app, only either one RecyclerView is displayed. If first view is displayed then it works properly and scrolls vertical, while second RecyclerView is missing. And if second one is displayed then it scrolls vertical when it should do horizontal scroll and the first RecyclerView is missing.
Here is what i want. Source: Github,CardView-Recyclerview-Picasso
Here is my layout
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/colorBackgroundLight"
android:smoothScrollbar="true"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.RecyclerView
android:id="#+id/CategoriesRecyclerView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<android.support.v7.widget.RecyclerView
android:id="#+id/videoRecyclerView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="130dp"
android:layout_below="#+id/CategoriesRecyclerView"/>
</RelativeLayout>
</android.support.v4.widget.NestedScrollView>

You may directly use the 2 Recycler Views without NestedScrollView.
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.RecyclerView
android:id="#+id/CategoriesRecyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<android.support.v7.widget.RecyclerView
android:id="#+id/videoRecyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="130dp"
android:layout_below="#+id/CategoriesRecyclerView"/>
</RelativeLayout>
And in your CategoriesRecyclerView whose height is wrap_content, use setAutoMeasureEnabled(true) on the Layout manager used for the recyler view.

If you want to scroll the horizontal scrollview full upside on page scroll then use scrollview otherwise you can do without scrollview. Also to achieve your layout just give the horizontal recyclerview fixed height and then you can see both recyclerview .
