This issue is occuring randomly and I am an intermediate in developing native android applications. This issue ossurs 1% of user engagements within the app. Randomly I can view crash reports of this in firebase crashlytics as follows

But when I start the application on the device it looks like this

Your activity_main.xml(or any layout that hosts recyclerview) should look like this.

android:layout_width="match_parent"

Check your adapter class, Layout you designed for adapter class should have width match parent and three different textviews with equal width to hold values.

Make sure the RecyclerView has layout_width also set to match_parent.

Pin ImageView and headed view in the top while scrolling and make the other view as scrollable in android

I need to pin the image while scrolling with the headed section and need to scroll other thing in the screen.
Here I need the header as fixed while scrolling and the half of the fill 2 image shown while scrolling.
Now the header actionsof on click are not working after addding nestedScrollView.
Also the nested view is overlapping with the above view while scrolling

Automatic scrolling when the keyboard is opened

I want the screen to automatically scroll up when the keyboard opens, so that the user can see what he has written.
The solution I found was to change the manifest and use adjustPan or adjustResize. I used both of them but it still didn't work.
Where is my mistake?
Thanks in advance.

You can do it simply doing by enclosing your error button inside the Relative Layout as following steps:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center">
<Button
android:id="#+id/retry"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:background="#null"
android:drawablePadding="10dp"
android:drawableTop="#drawable/ic_android"
android:gravity="center"
android:padding="6dp"
android:text="TRY AGAIN"
android:textColor="#000"
android:textSize="35sp"
android:visibility="visible" />
</RelativeLayout>

<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"/>
also you need a RelativeLayout for parent of this tag

Make the parent layout as RelativeLayout and put everything inside RelativeLayout except the button.
use
<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">
<!--Put your other codes here-->
<!--everything can be within LinerarLayout-->
<Button
android:id="#+id/retry"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:background="#null"
android:drawablePadding="10dp"
android:drawableTop="#mipmap/retry"
android:onClick="onClickRetry"
android:padding="6dp"
android:text="TRY AGAIN"
android:textColor="#000"
android:textSize="35sp"
android:visibility="gone" />
</RelativeLayout>
as your button code
