How do I prevent the keyboard from making my recyclerview items smaller?

So the problem is this. At first it looks good:
But when I open my keyboard the first two items in the way of the keyboard shrink a little bit
This is the XML code of the layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<androidx.cardview.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="5dp"
card_view:cardBackgroundColor="#EFE8E8"
card_view:cardCornerRadius="8dp"
card_view:cardElevation="10dp"
card_view:cardUseCompatPadding="false">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="100dp"
android:orientation="horizontal">
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginLeft="10dp"
android:layout_weight="1"
android:text="TextView"
android:textSize="20sp"
android:textStyle="bold"></TextView>
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_marginLeft="10dp"
android:layout_weight="1"
android:gravity="center_vertical"
android:text="TextView" />
<TextView
android:layout_width="match_parent"

android:layout_weight="1"

</LinearLayout>
</LinearLayout>
</androidx.cardview.widget.CardView>

And this is the XML code of my activity where the recyclerview is displayed:

Is there a way to prevent this?
Thanks for your help

Try this in your activity tag in manifest, add this line:
android:name=".SettingsActivity"
Like:
<activity
android:windowSoftInputMode="adjustPan"
android:name=".MyActivity"/>

Error Text
error: cannot find symbol variable place_autocomplete_search_button
I also want to change the hint text size of auto complete fragment

Please migrate to the latest SDK and use AutoCompleteSupportFragment
instead of AutoCompleteFragment.
For complete information related to migrating you can refer here.
After migrating for hiding the search button the id is,
places_autocomplete_search_button for the search Button.
places_autocomplete_search_input for the EditText.
So your code will be somewhat similar to this,
autocompleteSupportFragment.getView().findViewById(R.id.places_autocomplete_search_button).setVisibility(View.GONE);

I have created a basic template using your Layout in AndroidX. You can beautify it using your style, icons and colors accordingly. Please copy it and look at it in your Android Studio.

If I understand correctly, you're trying to place the "imageView2" ImageView on top of the "txtMessage" EditText, is that right?
If that's how it is, what you need to do is wrap both of them in a vertical LinearLayout, like so:
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<EditText
android:id="#+id/txtMessage"
android:layout_width="0dp"

android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"
android:layout_weight="1"
android:background="#android:color/transparent"
android:hint="Enter message"
android:maxLines="6" />
<ImageView
android:id="#+id/imageView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
app:srcCompat="#mipmap/ic_launcher" />
</LinearLayout>

<LinearLayout

I have used background drawable, you can replace with your add and send image.
Hope it solves your problem.

Here it is an image of the layout.
Also tried adding android:includeFontPadding="false" but everything is the same. Appreciate your efforts.

MATCH_PARENT is not recommended for widgets contained in a ConstraintLayout. Similar behavior can be defined by using MATCH_CONSTRAINT with the corresponding left/right or top/bottom constraints being set to "parent".
So add 0dp in width. Try below line of code.
<TextView
android:id="#+id/data"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:background="#fff"
android:padding="5dp"
android:textSize="18sp"
android:layout_gravity="fill"
app:layout_constraintVertical_bias="0"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintTop_toBottomOf="#id/shadow"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent" />

I have displayed single textview in layout.

How do I place one relative layout below another in a constraint layout?

I am looking at placing one relativelayout right below another in constraint layout and another button container overlaying the container at the bottom. How do I go about it?

any clues how to go about it?I actually want to place the callstatuscontainer on top of share or activespeaker container. I tried app:layout_constraintTop_toBottomOf="#+id/callStatusContainer"
in active speaker container, but no luck, any ideas?
