I faced with the following problem: ScrollView in my activity should be placed below ToolBar. Here's the layout of this activity:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.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=".SongLyricsActivity">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#0000FF"
tools:ignore="MissingConstraints" />
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_constraintTop_toBottomOf="#id/toolbar"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
android:layout_marginTop="16dp">
<TextView
android:id="#+id/lyrics_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</ScrollView>
</android.support.constraint.ConstraintLayout>
But when I run the app, I see this:
I don't understand, why it happens, as I position it below the toolbar, so, what's the matter?
I solved this problem using a marginTop parameter (equals to toolbar height), like this:
<ScrollView
android:id="#+id/activity_show_scroll_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="?attr/actionBarSize"
android:background="#color/transparent_background"
>
This works for my app.
This is happening because your scroll views height is match_parent and not 0dp - so your scroll view will not respect your constraints and will spread all over your screen.
Please notice that you are using tools:ignore="MissingConstraints" and the tool attribute will only affect the preview so you will see your layout in a different way from the preview.
In addition, you were missing some constraint - app:layout_constraintTop_toTopOf="parent"
Now with that constraint, it should work:
<?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:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#0000FF"
app:layout_constraintTop_toTopOf="parent"
tools:layout_editor_absoluteX="0dp" />
<ScrollView
android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_constraintTop_toBottomOf="#id/toolbar"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
android:layout_marginTop="16dp">
<TextView
android:id="#+id/lyrics_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</ScrollView>
</androidx.constraintlayout.widget.ConstraintLayout>
you might try:
<LinearLayout>
vertical
<RelativeLayout>
<Toolbar>
someID
parent top
parent left
<Scrollview>
below someID
parent left

I've got a simple application and I'm trying to add Bottom Sheet Behaviour. I want to keep Constraint Layout but I want to get Bottom Sheet Behaviour too. I don't want Coordinator Layout and Bottom Sheet Dialog.

<Button
android:id="#+id/button2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Button" />
</LinearLayout>
What I need to change to get this thing working?
For using that use Hierarchy like this for using constraint layout:
<CoordinatorLayout>
// *ViewGroup containing your fixed screen*
<Linear/Relative/Constraint Layout>
</Linear/Relative/Constraint Layout>
// *ViewGroup containing your bottom sheet*
<ConstraintLayout
app:behavior_hideable="false"
app:behavior_peekHeight="90dp"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior" >
</Constraintlayout>
</CoordinatorLayout>
Just add
app:layout_constraintBottom_toBottomOf="parent"
to you activity_shop.xml root
and change it's height to be wrap_content
I have the following code:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.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">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/imageView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:srcCompat="#tools:sample/avatars[1]" />
<!-- This is the element of interest.
View is actually a custom element, but for this example, View has same behavior -->
<View
android:id="#+id/MyView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#A4D38D14" />
</FrameLayout>
</android.support.constraint.ConstraintLayout>
Which results in the following. Orange is the size of the View of interest. No-matter what I try, it seems I cannot get the View to not expand the parent.
What I really want, is for the View to scale to the same height as the Image like this:
How can this be achieved?
Note: I do not know the size of the Image..
Please replace the code and you are good to go.
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.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">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:ignore="MissingConstraints">
<ImageView
android:id="#+id/imageView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:srcCompat="#tools:sample/avatars[1]" />
<View
android:id="#+id/MyView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/imageView"
android:background="#A4D38D14" />
</RelativeLayout>
</android.support.constraint.ConstraintLayout>
The key is to specify android:layout_alignBottom on the View and change the frame layout to relative layout
If I understand your question correctly, you may also try this
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

<ImageView
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
android:id="#+id/imageView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:srcCompat="#tools:sample/avatars[1]" />
<!-- This is the element of interest.
View is actually a custom element, but for this example, View has same behavior -->
<View
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#id/imageView"
app:layout_constraintBottom_toBottomOf="parent"
android:id="#+id/MyView"
android:layout_width="match_parent"
android:layout_height="0dp"
android:background="#A4D38D14" />
</android.support.constraint.ConstraintLayout>
I am posting this because as far as I am concerned ConstraintLayout is designed to use a single layout for the entire design,
I also faced a problem like you and figure out that the problem is generated for the <View> item. I fixed the problem by replacing the <View> with <Linearlayout>. Maybe <View> had a special characteristic that's why it is being overflown. My code snippet is -
<FrameLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<androidx.recyclerview.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<!-- This is the view intended to be the overlay-->
<LinearLayout
android:id="#+id/ll_overlay"
android:background="#color/colorAccent"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
</LinearLayout>
</FrameLayout>
I am trying to use constraint layout as below. But the aspect ratio is not respected in the actual layout. Instead, the height is actually wrapping the content inside
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/content"
android:layout_height="0dp"
android:layout_width="match_parent">
<!-- some content inside -->
</android.support.constraint.ConstraintLayout>
I then think it might be because I didn't set width="0dp" (let constraint decide the width). So I tried another way like below. But then the width becomes zero.
What is the correct way of doing it?
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/content"
android:layout_height="0dp"
android:layout_width="0dp"
app:layout_constraintStart_toEndOf="parent"
app:layout_constraintEnd_toEndOf="parent">
<!-- some content inside -->
</android.support.constraint.ConstraintLayout>
EDIT: working solution after inspired by Anddenver 's answer (with modification):
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto">
<FrameLayout
android:background="#android:color/holo_green_dark"
android:layout_width="0dp"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
android:layout_height="0dp"
app:layout_constraintDimensionRatio="2:1">
</FrameLayout>
</android.support.constraint.ConstraintLayout>
Further Edit:
It seems I need to wrap one more layer of constraint layout for my inner contents .... :
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto">
<FrameLayout
android:background="#android:color/holo_green_dark"
android:layout_width="0dp"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
android:layout_height="0dp"
app:layout_constraintDimensionRatio="2:1">
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<actual contents here..../>
</android.support.constraint.ConstraintLayout>
</FrameLayout>
</android.support.constraint.ConstraintLayout>
Or, just remove the FrameLayout, and wrap ConstraintLayout inside a ConstraintLayout:
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto">
<android.support.constraint.ConstraintLayout
android:background="#android:color/holo_green_dark"
android:layout_width="0dp"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
android:layout_height="0dp"
app:layout_constraintDimensionRatio="2:1">
contents here...
</android.support.constraint.ConstraintLayout>
</android.support.constraint.ConstraintLayout>
You need inner view for that, for example:
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<FrameLayout
android:background="#color/colorPrimary"
android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_constraintDimensionRatio="1:1">
<YOUR CONTENT>
</FrameLayout>
For a ListView, you'd need to inflate a custom list_item.xml
and this should be H,2:1, to constrain the height to a 2:1 aspect ratio.
The default android.R.layout.simple_list_item_1 is just a TextView:
<?xml version="1.0" encoding="utf-8"?>
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/text1"
android:layout_height="0dp"
android:layout_width="0dp"
app:layout_constraintDimensionRatio="H,2:1"
...
/>
see DimensionConstraints.
My goal is to place a "bottom sheet" on top of a BottomNavigationView like this:
But it stays the following way. Both views collapse:
This is the xml of my main activity:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
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"
android:background="#drawable/tierrota"
tools:context="com.example.juanjose.myapplication.ViajesActivity">
<!-- include main content -->
<include layout="#layout/bottomsheet" />
<!-- include bottom sheet -->
<include layout="#layout/bottom_navigation" />
</android.support.design.widget.CoordinatorLayout>
Code of bottom_navigation:
<?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.support.design.widget.BottomNavigationView
android:id="#+id/bottom_navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
app:itemBackground="#color/colorClarito"
app:itemIconTint="#drawable/nav_item_color_state"
app:itemTextColor="#drawable/nav_item_color_state"
app:menu="#menu/bottom_navigation_main" />
</RelativeLayout>
And code of bottom sheet
<?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"
android:id="#+id/bottom_sheet"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
app:behavior_hideable="false"
app:behavior_peekHeight="80dp"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior">
<TextView
android:layout_width="match_parent"
android:layout_height="80dp"
android:background="#color/colorBackgroundSemi"
android:gravity="center"
android:text="Bandeja de entrada"
android:fontFamily="#font/eraslght"
android:textColor="#color/colorLetra"
app:layout_anchor="#+id/bottom_navigation"
app:layout_anchorGravity="top"/>
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:text="coisa2"
android:textColor="#android:color/white" />
</LinearLayout>
I am new with these two elements. Is there someone who knows any way to achieve what I'm looking for?
I want my "bottom sheet" to act as such and can expand. My ultimate goal is to add a RecyclerView inside the BottomSheet.
To use the BottomSheet, it should be a child of the CoordinatorLayout. Here I have used relative layout as a parent layout for bottom navigation to stay at the bottom and then CoordinatorLayout above bottom navigation.
Here's a article that will help you.
<?xml version="1.0" encoding="utf-8"?>
<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:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/transparent">
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_above="#id/bottom_navigation_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="?attr/colorPrimary" />
</RelativeLayout>
<RelativeLayout
android:id="#+id/bottom_sheet_parent"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#000000"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior">
<LinearLayout
android:id="#+id/bottom_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<View
android:layout_width="20dp"
android:layout_height="4dp"
android:layout_gravity="center"
android:layout_marginTop="10dp"
android:background="#drawable/view_bottom_sheet_top" />
<TextView
android:id="#+id/near_by"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fontFamily="#font/normal"
android:gravity="center"
android:includeFontPadding="false"
android:padding="10dp"
android:text="Book Now"
android:textAllCaps="true"
android:textColor="?attr/colorPrimaryText"
android:textSize="12sp" />
</LinearLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view_maps"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/bottom_view"
android:layoutAnimation="#anim/layout_animation">
</android.support.v7.widget.RecyclerView>
</RelativeLayout>
</android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.AppBarLayout
android:id="#+id/bottom_navigation_parent"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:fitsSystemWindows="true"
app:elevation="1dp">
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#color/colorContainerBackground"
/>
<!-- Start BottomNavigationView -->
<!-- End BottomNavigationView -->
</android.support.design.widget.AppBarLayout>
</RelativeLayout>
Don't forget to add this in your Activity/Fragment
private RelativeLayout bottomSheetParentLayout;
private BottomSheetBehavior mBottomSheetBehaviour;
mBottomSheetBehaviour = BottomSheetBehavior.from(bottomSheetParentLayout);
if (bottomNavigation != null) {
mBottomSheetBehaviour.setPeekHeight(bottomNavigation.getHeight() + 90);
}
Wrap the two elements inside a linear layout. Not sure how coordinator layout behaves but I think it will not allow you to "order" elements (similar to frame layout).
As far as I have understood your question, you want the RecyclerView to be shown in your bottom sheet. That is what makes the problem a lot easier. Let me tell you how.
You need to have a fixed height for your bottom navigation like this.
<?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.support.design.widget.BottomNavigationView
android:id="#+id/bottom_navigation"
android:layout_width="match_parent"
android:layout_height="80dp"
android:layout_alignParentBottom="true"
app:itemBackground="#color/colorClarito"
app:itemIconTint="#drawable/nav_item_color_state"
app:itemTextColor="#drawable/nav_item_color_state"
app:menu="#menu/bottom_navigation_main" />
</RelativeLayout>
Now in your bottom sheet, configure the RecyclerView with a clipToPadding attribute in it. Which will have some padding at the bottom of your RecyclerView. The idea is to have nothing in the covered area of the RecyclerView which is coming out with the bottom sheet.
Here's how you should declare your RecyclerView in your bottom sheet.
<android.support.v7.widget.RecyclerView
android:id="#+id/my_list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipToPadding="false"
android:paddingBottom="80dp" />
Note that, I set the paddingBottom exactly to 80dp which is the height of the navigation view.
I hope this might help.
If you also have a CollapsingToolBar/Toolbar arrangement, this is the best solution for you:
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true">
<androidx.coordinatorlayout.widget.CoordinatorLayout
android:id="#+id/cord_main_content"
android:layout_width="match_parent"
android:layout_height="0dp"
android:fitsSystemWindows="true"
app:layout_constraintBottom_toTopOf="#id/home_bottom_navigation_view"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
<com.google.android.material.appbar.AppBarLayout
android:id="#+id/home_appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<androidx.appcompat.widget.Toolbar
android:id="#+id/home_frag_toolbar"
style="#style/Widget.Toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:logo="#drawable/ic_infinet_logo_white"
app:navigationIcon="#drawable/ic_back_arrow" />
</com.google.android.material.appbar.AppBarLayout>
<FrameLayout
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:id="#+id/home_frag_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<FrameLayout
android:id="#+id/bottom_sheet_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/white"
android:clickable="true"
app:behavior_hideable="true"
app:behavior_peekHeight="#dimen/mini_player_height"
app:behavior_skipCollapsed="false"
app:layout_behavior="com.google.android.material.bottomsheet.BottomSheetBehavior">
<FrameLayout
android:id="#+id/player_frag_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<fragment
android:id="#+id/player_mini_frag_container"
android:name="com.kokonetworks.kokonet.player.PlayMusicMiniFragment"
android:layout_width="match_parent"
android:layout_height="#dimen/mini_player_height" />
</FrameLayout>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
<com.google.android.material.bottomnavigation.BottomNavigationView
android:id="#+id/home_bottom_navigation_view"
android:layout_width="match_parent"
android:layout_height="56dp"
android:layout_alignParentBottom="true"
android:background="#color/colorPrimary"
app:itemBackground="#color/colorPrimary"
app:itemHorizontalTranslationEnabled="false"
app:itemIconTint="#drawable/nav_item_background"
app:itemTextColor="#drawable/nav_item_background"
app:labelVisibilityMode="auto"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:menu="#menu/home_bottom_navigation_menu" />
</androidx.constraintlayout.widget.ConstraintLayout>
It ensures that:
BottomSheet is a child of the CoordinatorLayout
BottomNavigation is still rested at the bottom
CollapsingToolbar/AppBarLayout arrangement is still in place as expected
To use the BottomSheet, it should be a child of the CoordinatorLayout, as iamnaran said.
So simply:
Put everything in RelativeLayout
Put BottomSheet in CoordinatorLayout
Set the BottomNavigation property "alignParentBottom" to true
Make new xml file in /res/value and put
<resources>
<dimen name="bottomNavigationHeight">50dp</dimen>
</resources>
Set the MarginBottom of the CoordinatorLayout (parent of BottomSheet) to
android:layout_marginBottom="#dimen/bottomNavigationHeight"
You can skip steps 4 and 5 by setting the MarginBottom of the CoordinatorLayout to:
android:layout_marginBottom="50dp"
But this may lead to confusion in near future
The whole code should look something like this:
<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"

I want a layout above recycler view at the bottom of the screen,(like a frame) so that even when that layout is visible I can still scroll recycler view behind it. So I want to align the frame layout at the bottom of the screen and make it visible and invisible as per requirement. Here is my code.
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.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="com.protossoft.root.aesencryption.MainActivity">
<ListView
android:layout_width="match_parent"
android:id="#+id/listView"
android:layout_height="match_parent">
</ListView>
<!-- <RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">-->
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:layout_editor_absoluteX="0dp"
tools:layout_editor_absoluteY="443dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:gravity="center"
android:orientation="horizontal">
<ImageView
android:id="#+id/deviceNumberImage"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.2"
android:src="#android:drawable/btn_default" />
<TextView
android:id="#+id/deviceNumber"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.8"
android:text="990000862471854" />
</LinearLayout>
</FrameLayout>
<!-- </RelativeLayout>-->
I don't have too much of idea about constraint layout, but when I am moving the view at the bottom from the editor, it is using property like
tools:layout_editor_absoluteX="0dp"
tools:layout_editor_absoluteY="443dp"
I want to achieve the same with some property like align_parentBottom. But none of the properties is available for use. What do I need to do so that the frame layout is visible at the bottom and on the top of recycler view at the same time?
Thanks :)

You should use app:layout_constraintBottom_toBottomOf="parent" attribute.
Here's the setup that you need:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent">
...
</FrameLayout>
</android.support.constraint.ConstraintLayout>
