How to add recylerview in 1/3rd part of activity

I have on activity in which i need to add one horizontal list for showing the formats of image which should be appear in the lower part of the activity. Here is my xml file.

It should look like this:
But this recyler-view while loading taking the whole space of the activity and one header also. Can you tell me what is wrong in this? Can recyler-view won't be able to host inside this view.

The issue is that you don't have a top to bottom of constraint and have set the height as match constraints.. However for layouts like this i have a few tips..
do the layouts first with constant heights like 200 dp or so and change them later
follow a top to bottom or a bottom to top approach that is one view at the top and everything else is done taking that as anchor
use constraint layouts throughout. You don't need any other layout type if you're using constraint layout

windowSoftInput hides items in recycleview

Im creating a chat app and so far it looks something like this:
The moment I start typing it hides the last 2 items and looks like (the edittext hides g,h messages):
My XML file looks as follows:
<?xml version="1.0" encoding="utf-8"?>

app:layout_constraintStart_toStartOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
and I have added to my manifest android:windowSoftInputMode="adjustPan"
Is there a way that I can make sure that my recycleview will always show the lates messages/ make sure the edittext wont hide?
Thank you

Use the combination of relative and linear layout and then use marginBottom inside recyclerview. Hope you will find it.

Layout in fragment not centering

I'm building my first proper application for Android. I wish to use the Navigation Drawer Activity to switch between screens and options. So far so good. All working great. But my layouts that load in the content are not aligned properly. See pictures
I have tried to change the layout_width and layout_height to fill_parent, match_parent and wrap_content in all combinations. Also tried adding the gravity center and vertical gravity but so far i have failed.
content layout:

This is what i expect it to look like:
But in reality this is what it looks like:

The issue in your RelativeLayout inside your content layout
You need to chnage the width of your RelativeLayout to android:layout_width="match_parent" in your content layout
Try this
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:showIn="#layout/app_bar_main_menu"
tools:context=".MainMenu">
<RelativeLayout
android:id="#+id/relativeLayout"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</androidx.constraintlayout.widget.ConstraintLayout>

The problem is not with your fragment layout implementation, I just tried in an activity and it is worked properly.
I would say to change the content layout to FrameLayout, which is often used to hold the fragments, more information can be found here :Why is a FrameLayout used for fragments?
The frame layout instead of relative layout should be
<FrameLayout
android:id="#+id/relativeLayout"
android:layout_width="match_parent"
android:layout_height="match_parent" />
Just left the id as relativeLayout, but feel free to change it.
Also, if you have such a problem, you can always use the layout inspector, it is in the tools menu, give it a try. Or you can just play with background colors, to check the layout sizes, just like back in time, before layout inspector.

It is always good to use drawablestart instead of imageview in all edit text
Please find below xml may it will be helpful

In case you want specific size for your imageview in left use below code
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
>
<item
android:drawable="#drawable/icon"
android:width="#dimen/icon_size"
android:height="#dimen/icon_size"
/>
</layer-list >

Use FrameLayout instead of relative layout and finally remove the line from parent constraint layout..
tools:layout_editor_absoluteY="81dp"

try to use like below
<?xml version="1.0" encoding="utf-8"?>
<androidx.appcompat.widget.LinearLayoutCompat
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_gravity="center_vertical"
android:gravity="center_vertical"
android:layout_height="match_parent">
<ImageView
android:layout_width="34dp"
android:layout_height="34dp"
app:srcCompat="#drawable/fragment_client_add_address"
android:id="#+id/imageView10"
android:layout_marginEnd="12dp"
android:layout_marginTop="8dp"/>
</androidx.appcompat.widget.LinearLayoutCompat>
And for content main
<androidx.appcompat.widget.LinearLayoutCompat
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<FrameLayout
android:id="#+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</androidx.appcompat.widget.LinearLayoutCompat>

You can use the property app:layout_constraintVertical_bias so that it is biased equally to parent. This can also be achieved in layout editor by constraining all 4 sides of the layout to parent.

Android: LinearLayout going out of screen when using weight

Why is 3rd linear layout (containg two text views) being pushed out of screen in following xml file? Simultaneous design in Android Studio is showing expected behaviour but when testing in phone, 3rd linear layout is being partially visible.
What I am trying to achieve is dividing screen into 3 parts (10%, 80% and 10%).
<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">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:orientation="horizontal">
<TextView
android:id="#+id/messageTextView"
android:layout_height="match_parent"
android:layout_width="0dp"
android:layout_weight="3"
android:text="Place a stone" />
<Button
android:id="#+id/resetButton"
android:layout_height="match_parent"
android:layout_weight="1"
android:layout_width="0dp"
android:text="Reset" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="8">
<me.varunon9.fito.CanvasBoardView
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:orientation="horizontal">
<TextView
android:id="#+id/userInfoTextView"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="match_parent"
android:background="#drawable/focussed_background"
android:text="Your turn\nStones left: 9" />
<TextView
android:id="#+id/computerInfoTextView"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="match_parent"
android:text="Computer's turn\nStones left: 9" />
</LinearLayout>
Even this xml is also being pushed out of screen-
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/root"
android:layout_width="match_parent"
android:layout_height="match_parent">

android:layout_height="40dp"
android:id="#+id/topBar"
android:orientation="horizontal"
android:layout_alignParentTop="true">
<TextView
android:id="#+id/messageTextView"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:text="Place a stone" />
</LinearLayout>
<View
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="40dp"
android:layout_marginBottom="40dp"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="40dp"
android:id="#+id/bottomBar"
android:layout_marginBottom="0dp"
android:orientation="horizontal"
android:layout_alignParentBottom="true">
<TextView
android:id="#+id/userInfoTextView"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:text="User Info" />
</LinearLayout>
</RelativeLayout>
I am using Fragment (Tabbed Activity). When using same xml layout (above snippets) in activity, things are working fine. Problem seems with Fragment.

To avoid nested weights (bad for performance), you can use Relative layout.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/root"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="40dp"
android:id="#+id/topBar"
android:orientation="horizontal"
android:layout_alignParentTop="true"/>
<View
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="40dp"
android:layout_marginBottom="40dp"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="40dp"
android:id="#+id/bottomBar"
android:orientation="horizontal"
android:layout_alignParentBottom="true"/>
</RelativeLayout>

Instead of using nested weights, which happen to be terribly bad for performance, use ConstraintLayout which is very easy to implement in the layout editor.
If you have never used it before it can appear to be a bit complicated; but that is not the case. Refer to this link to get an idea on how to implement a ConstraintLayout.
Here is the code for what you want to achieve
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

Found it! Problem was not with fragment layout but its container, i.e. ViewPager. I am using Tabbed Activity and by default View Pager was too long (going out of screen).
Here is the solution: Android Tabbed Activity Bottom off Screen
Thanks for effort guys.

Hiiii
I think you don't have proper info, how to use "Weightsum".
well no issue, i will explain you,
When you want to use "Weight" in linear layout you should use "Weightsum" in your main "LinearLayout" after that you can use sub layout or widgets in sum of weight like below code.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="1"
android:orientation="horizontal">
<TextView
android:id="#+id/messageTextView"
android:layout_height="match_parent"
android:layout_width="0dp"
android:layout_weight="0.5"
android:text="Place a stone" />
<Button
android:id="#+id/resetButton"
android:layout_height="match_parent"
android:layout_weight="0.5"
android:layout_width="0dp"
android:text="Reset" />
</LinearLayout>

android scrollview not scrolling down after keyboard opens

I have a textview that is inside of a scrollview, it scrolls fine untill the soft keyboard is opened.
When the keyboard is opened it act like it scrolled up again with the height of the keyboard.
What I have tried
I tried this in the manifest, but yielded the exact same results
android:windowSoftInputMode="adjustResize"
Then this:
android:windowSoftInputMode="adjustPan"
That seemed to work, but the problem was that it was moving the whole screen up and taking the header out of view.
I also tried adding the following in the linear layout
android:focusable="true"
android:focusableInTouchMode="true"
That only caused the app not to focus on the input field (EditText) and the keyboard didn't open automatically, but when you clicked on the input field it would just act the same as before.
This is the XML file code:
<?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"
android:background="#color/lightGray"
android:orientation="vertical" >
<ScrollView
android:id="#+id/scrollView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/bottom_layout"
android:layout_marginTop="10dip" >
<LinearLayout
android:id="#+id/msg_list_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
</LinearLayout>
</ScrollView>
<RelativeLayout
android:id="#+id/bottom_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="#android:color/background_light">
<Button
android:id="#+id/send_btn"
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="#string/txt_send" />
<EditText
android:id="#+id/msg_edit"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/send_btn"
android:layout_toLeftOf="#+id/send_btn"
android:inputType="text" >
</EditText>
</RelativeLayout>
Any suggestions?

I had same problem and the solutions is this:
My activity was in fullscreen mode and scroll does not work in this mode this is a bug and we send a report to google.
Just look at your activity in manifest if there is a fullscreen mode just remove it.

I got this problem and it is a headache.
the soloution is instead of drawing an XML layout from the top of the screen, you need to draw it from the bottom of the screen.
look at these examples :
main.xml

the second XML file main_contents2 drew from top and android just put the EditText from top of the keyboard.BUT the main_contents drawn from the bottom of the screen. so when the soft keyboard comes up the layout resizes.

Try changing the layout_height of scrollview to wrap_content.

All you need to do is
android:isScrollContainer="true"
