I've been using the new Androidx libraries and have run into an issue I cannot fix. I am using RecyclerView and just cannot get the row to wrap. It is supposed to do it, and everything I read seems to be that it just works if I cannot get it right. I have used this previously and did not have this issue. I've tried adjusting every setting in both my main layout and the item layout, but nothing seems to affect it. Any help would be appreciated.
main_activity.xml

OK in my case , in item.xml, the height was given "match_parent". After I converted it into "wrap_content", the recycle view height was expanded according to the number of items. Note that I am using the androidx library as well.
The item.xml code was like this
<LinearLayout 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:orientation="horizontal"
android:padding="#dimen/small_padding">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/tickred"
android:layout_marginStart="0dp"
android:layout_marginTop="1dp"
android:layout_gravity="top"
android:layout_marginEnd="#dimen/dimen_margin_between_text"/>
<androidx.appcompat.widget.AppCompatTextView
android:layout_width="0dp"

android:layout_gravity="top"
android:gravity="top"
app:fontFamily="#font/lato_regular"
android:textColor="#color/black"
android:textSize="#dimen/dimen_text_smallx"/>
</LinearLayout>
I changed the container height to wrap_content and the recycleview takes its height accordingly.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"

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.
I am making an app in which I have a RecyclerView. I have also added a button, but it isn't shown. See the left photo. What I now want is to make the RecyclerView so that may button is visible, like in the photo on the right. How can I achieve this?
Under the photos you can see my xml code. I'd like the RecyclerView to be relative/dynamic.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

The problem is that you set the CardView height to match_parent so it takes up the entire screen. It's best to use ConstraintLayout for these kinds of layouts, but you can also fix it with minimal effort like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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="com.test.test.MainActivity"
android:orientation="vertical"
android:background="#color/colorAccent">
<include
android:id="#+id/toolbar"
layout="#layout/toolbar"/>
<androidx.cardview.widget.CardView
android:id="#+id/cardViewMiddle"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_marginRight="20dp"
android:layout_marginLeft="20dp"
android:layout_marginTop="20dp"
android:layout_marginBottom="20dp"
android:layout_weight="1"
app:cardCornerRadius="15dp">
<androidx.core.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/recyclerview"
android:layout_width="match_parent"
android:layout_height="match_parent">
</androidx.recyclerview.widget.RecyclerView>
</androidx.core.widget.NestedScrollView>
</androidx.cardview.widget.CardView>
<Button
android:id="#+id/btnCheckout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/round_corner"
android:backgroundTint="#color/colorPrimaryDark"
android:elevation="16dp"
android:text="START"
android:textColor="#FFFFFF"
android:textStyle="bold" />
</LinearLayout>
Note I only changed CardView's layout_height to 0dp and then added the following:
android:layout_weight="1"
Which will tell the layout to stretch as much as it can (while not covering other elements below it).
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.
I am trying to add a custom header in my main activity that already contains a bottom navigator and a framelayout that acts as a container for the fragments i want to display.
The below given code contains a Linearlayout["#+id/application_header] that should act as the application header, however the header is displayed by the fragment container[#+id/main_container] is overlapping the header.
Tried the properties android:layout_below and android:layout_above but it is still overlapping.

android:layout_below and android:layout_above work with RelativeLayout. BTW, the LinearLayout with only one TextView is redundant. You can just use TextView. Here are some options on how to get that done.
Using RelativeLayout:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:design="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:id="#+id/application_header"
android:layout_width="match_parent"
android:layout_height="50dp">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="RADIO"/>
</LinearLayout>
<FrameLayout
android:id="#+id/main_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/bottomNavigationBar"
android:layout_alignParentTop="true"
android:layout_below="#id/application_header">
</FrameLayout>
<android.support.design.widget.BottomNavigationView
android:id="#+id/bottomNavigationBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="#50b1b5b9"
design:menu="#menu/bottom_menu_navigation">
</android.support.design.widget.BottomNavigationView>
</RelativeLayout>
Using LinearLayout:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:design="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:id="#+id/application_header"
android:layout_width="match_parent"
android:layout_height="50dp">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="RADIO"/>
</LinearLayout>
<FrameLayout
android:id="#+id/main_container"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
<android.support.design.widget.BottomNavigationView
android:id="#+id/bottomNavigationBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:background="#50b1b5b9"
design:menu="#menu/bottom_menu_navigation">
</android.support.design.widget.BottomNavigationView>
</LinearLayout>
One more (better) alternative would be using CoordinatorLayout with Toolbar:
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:design="http://schemas.android.com/tools">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay"/>
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:id="#+id/main_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/application_header"
android:layout_above="#+id/bottomNavigationBar"
android:layout_alignParentTop="true"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
<android.support.design.widget.BottomNavigationView
android:id="#+id/bottomNavigationBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
design:menu="#menu/bottom_menu_navigation"
android:background="#50b1b5b9"/>
</android.support.design.widget.CoordinatorLayout>
Solved it my self, although there might other clean solution and would be accepted as answer if found feasible.
I just added android:layout_marginTop="50dp" which is same as the height of element with id - #+id/application_header
PS- i don't know if this would effect screens with different sizes and my testing device is only 5.5 inches to which the solution worked perfectly.
You can also make the layout align center of the screen by adding this :
android:layout_centerInParent="true"
also add a padding or margin incase there is any small amount of overlapping
I have a FloatActionButton that have to stick out a bit from the view that contains it, but it becomes cutted.
How can I obtain it to get out a bit from the container?

Make your view taller with a transparent background and change the background of your edittext to the darker color if you want
