How to remove empty white space at the bottom of the screen in NestedScrollView?

I'm using a NestedScrollView to make the carousel and viewPager scrollable. I added the carousel on the main layout because I need it on all pages from the tab layout. All the pages of the tab layout have only a recycler view in the fragment. The problem is that on the bottom of the screen there is a lot of empty white space that I can't figure out how to remove.
This is the main layout activity xml

I tried all the answers I could find on stackoverflow (you can see all the attributes on the NestedScrollView) but none of them fixed my problem.

Android RecyclerView Gravity issue

I am using DrawerLayout to show Navigation Drawer, in that A NavigationView, the xml code is :
MyDrawerLayout.xml
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true">
<include layout="#layout/layout_navigation_list" />
</android.support.design.widget.NavigationView>
layout_navigation_list.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/white"
android:orientation="vertical">
<include
android:id="#+id/headerLayout"
layout="#layout/nav_header_dash_nav"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_gravity="top"
android:gravity="top" />
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerNav"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/headerLayout"
android:layout_alignParentBottom="true"
android:layout_gravity="bottom"
android:background="#color/white"
android:foregroundGravity="bottom" />
</RelativeLayout>
In the RecyclerView i have only 3 items to be shown, and they are aligning on the top of the RecyclerView layout which is i don't want. Hence my question here is , how to send those items to the bottom of the RecyclerView (just like shown in the image).

Set match_parent instead wrap_content field layout_height in relativeLayout :
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/white"
android:orientation="vertical">

Insert a ConstraintLayout
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:background="#color/white"
android:orientation="vertical">
<include
android:id="#+id/headerLayout"
layout="#layout/nav_header_dash_nav"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_gravity="top"
android:gravity="top" />
<android.support.constraint.ConstraintLayout
android:layout_below="#id/headerLayout"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerNav"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/white"
app:layout_constraintBottom_toBottomOf="parent"
/>
</android.support.constraint.ConstraintLayout>
</RelativeLayout>

You should have to MATCH_PARENT height instead of WRAP_CONTENT in root relative layout in file layout_navigation_list.xml. So it looks like,
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/white"
android:orientation="vertical">
...
...
...
</RelativeLayout>
Notes: Gravity won't work with relative layouts.

Vertically scrolling two frame layout or fragment

I have tried this-
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
android:isScrollContainer="true"
android:layout_below="#+id/rootLayout"
android:layout_centerHorizontal="true">
<RelativeLayout
android:id="#+id/rootLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<FrameLayout
android:id="#+id/shop_detail_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true" />
<FrameLayout
android:id="#+id/item_detail_container"
android:layout_width="match_parent"
android:layout_alignParentBottom="true"
android:layout_height="wrap_content" />
</RelativeLayout>
</ScrollView>
I'm trying to get two vertically scrollable fragments in one screen. The above code is only showing fragment one and it's also not scrolling. Any help will be appreciated.
Thank you in advance.

Fragments are overlapping in your case. if you want to use Relative layout then use it as below,
<RelativeLayout
android:id="#+id/rootLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<FrameLayout
android:id="#+id/shop_detail_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true" />
<FrameLayout
android:layout_below="#id/shop_detail_container"
android:id="#+id/item_detail_container"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</RelativeLayout>
or use Linear layout as below,
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:orientation="vertical"
android:id="#+id/rootLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<FrameLayout
android:id="#+id/shop_detail_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<FrameLayout
android:id="#+id/item_detail_container"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</android.support.v4.widget.NestedScrollView>

Try it like this it worked for me
<LinearLayout...orientation = "horizontal>
<ScrollView>
<FrameLayout/>
</ScrollView>
<ScrollView>
<FrameLayout/>
</ScrollView>
</LinearLayout>

</ScrollView>
thanks in advance

Do this
1) Change root layout to RelativeLayout
2) Set height of ScrollView to wrap_content
3) Change height of ScrollView child which is LinearLayout to
match_parent
4)add this line to Host activity of that fragment
<activity
android:name="Activity_name"
android:windowSoftInputMode="stateHidden|adjustResize" />
Finally the xml looks like:-
<RelativeLayout 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:id="#+id/rootView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/white"
android:fillViewport="true"
android:orientation="vertical"
tools:context=".ui.jobCalendar.JobCalendarFragment">
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/white"
android:fillViewport="true"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<com.applandeo.materialcalendarview.CalendarView
android:id="#+id/calendarView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:headerColor="#color/colorPrimaryDark" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/bg_calendar"
android:orientation="vertical">

android:layout_height="wrap_content"

android:layout_marginBottom="8dp"
android:layout_marginTop="#dimen/activity_vertical_margin"
android:padding="10dp"
android:text="Schedule"
android:textColor="#color/white"
android:textSize="16sp" />
</LinearLayout>
<android.support.v4.widget.SwipeRefreshLayout
android:id="#+id/swipe_refresh_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.RecyclerView

android:layout_width="match_parent"
android:layout_height="wrap_content"

tools:listitem="#layout/job_row">
</android.support.v7.widget.RecyclerView>
</android.support.v4.widget.SwipeRefreshLayout>
</LinearLayout>
</LinearLayout>
</ScrollView>
</RelativeLayout>

I think you need to get rid of those settings inside the ScrollView attribute.
Basically short it down to
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
Put the rest of the settings inside a RelativeLayout that is included inside the ScrollView like this:
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
======== put all the rest of your settings from scrollvide here =====>
<CONTENT> add here the rest of your code </CONTENT>
</RelativeLayout>
</Scrollview>

android layout with fragment breaks when toolbar is there

Couldn't find a more appropriate title but my problem is the following. I have a LinearLayout that contains another LinearLayout and a fragment. I also want to add the toolbar but when I do so, then I only see the toolbar and the other screen is just white.
Here is the layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
tools:context="xeniasis.mymarket.MainActivity">
<include
android:id="#+id/toolbar"
layout="#layout/toolbar" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:baselineAligned="false"
android:weightSum="4">
<LinearLayout
android:id="#+id/categories_layout"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:paddingRight="20dp">
<ExpandableListView
android:id="#+id/categories_listView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
<fragment
android:id="#+id/mainPane"
android:name="xeniasis.mymarket.Products"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="3"
tools:layout="#layout/activity_main" />
</LinearLayout>
</LinearLayout>
Toolbar:
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:elevation="4dp"
android:padding="5dp"
android:theme="#style/ToolbarTheme" />
And the fragment layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="xeniasis.mymarket.MainActivity">
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/swipeRefreshContainer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="8dp"
android:paddingRight="8dp"
android:paddingTop="#dimen/activity_vertical_margin">
<GridView
android:id="#+id/productsGridview"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:numColumns="3"></GridView>
</android.support.v4.widget.SwipeRefreshLayout>
<android.support.design.widget.FloatingActionButton
android:id="#+id/settings"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|start"
android:layout_margin="8dp"
android:clickable="true"
android:elevation="5dp"
android:src="#android:drawable/ic_menu_search" />
</android.support.design.widget.CoordinatorLayout>
</LinearLayout>
This only happens when I have a fragment, cause I previously had the same xml with a static layout where the fragment is now.

The problem is that you used a LinearLayout with
android:orientation="horizontal"
and since the toolbar has match_parent as width it occupies all the screen.
Try to use
android:orientation="vertical"
in the root layout
