Change background color on hover of a CardView

I want to change background color to my CardView in Android Studio, I want to use selector, but I dont know what I do
This in my code:
<androidx.cardview.widget.CardView
android:id="#+id/card_ordina"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="15dp"
app:cardBackgroundColor="#color/orange"
app:cardCornerRadius="20dp">
<ImageView
android:layout_width="80dp"
android:layout_height="80dp"
android:layout_gravity="center_horizontal"
android:layout_marginLeft="30dp"
android:layout_marginTop="20dp"
android:layout_marginRight="30dp"
android:layout_marginBottom="40dp"
android:background="#drawable/options"
android:backgroundTint="#F44336"
android:padding="10dp"
android:src="#drawable/carrello"
android:tint="#color/background" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|center"
android:layout_marginBottom="5dp"
android:fontFamily="#font/title"
android:text="ORDINA"
android:textColor="#color/background"
android:textSize="18sp" />
</androidx.cardview.widget.CardView>

You need to make a selector and set the following attributes to your CardView.
android:foreground="#drawable/card_foreground"
android:clickable="true"
android:focusable="true"
Here is the code for card_foreground.xml, add it in your project's drawable folder.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true">
<shape android:shape="rectangle">
<solid android:color="#e0F5AD6E"/>
<corners android:radius="2dp" />
</shape>
</item>
<item android:state_focused="true" android:state_enabled="true">
<shape android:shape="rectangle">
<solid android:color="#0f000000"/>
<corners android:radius="2dp" />
</shape>
</item>
</selector>
You can change the state colors and radius according to your requirements. Now, when you click on the CardView the color will get changed.

style="#style/buttonBackStyle"
android:id="#+id/btnBack"
android:background="#drawable/ic_left_arrow_2"
android:layout_width="15dp"
android:layout_height="15dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<Button
android:onClick="openEditScreen"
android:id="#+id/btnEditPofile"
android:layout_width="15dp"
android:layout_height="15dp"
android:background="#drawable/ic_edit_profile"
android:gravity="end"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent" />

Thank in advance

Instead of button you can use this and implement click event of framelayout.
<FrameLayout
android:id="#+id/button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="<Your Background image>">
<TextView
android:id="#+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="<Your text>"
android:textSize="18sp" />
<ImageView
android:id="#+id/image"
android:layout_width="20dp"
android:layout_height="20dp"
android:layout_gravity="right|center"
android:layout_marginRight="10dp"
android:gravity="center|right"
android:src="<image drawable>" />
</FrameLayout>

Mixing code from Add drop shadow effects to EditText Field and answer from babar sanah I was able to find the solution.
My solution is as below:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<!-- most important in order of layers -->
<!-- Bottom right side 2dp Shadow -->
<item >
<shape android:shape="rectangle">
<gradient
android:angle="270"
android:endColor="#333333"
android:centerColor="#86ae0b"
android:startColor="#666666" />
</shape>
</item>
<!-- Bottom 2dp Shadow -->
<item>
<shape android:shape="rectangle">
<gradient
android:angle="270"
android:endColor="#333333"
android:centerColor="#86ae0b"
android:startColor="#666666" />
</shape>
</item>
<!-- White Top color -->
<item android:top="5px" android:left="5px">
<shape android:shape="rectangle">
<gradient
android:angle="-90"
android:endColor="#333333"
android:centerColor="#86ae0b"
android:startColor="#666666" />
</shape>
</item>
</layer-list>
Thanks alot for the help it means a lot to me.

Why you didn't try gradient? If it is possible please let me know..
<gradient
android:angle="270"
android:centerColor="#color/shadow_alpha"
android:endColor="#color/shadow_alpha1"
android:startColor="#color/shadow_alpha2" />
Define the colors as per your need..

create an xml shape.xml put in drawable folders and give your edit text background
android:background="#drawable/shape"
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle"
android:padding="10dp">
<!-- you can use any color you want I used here gray color-->
<gradient android:angle="-90"
android:endColor="#436EEE"
android:startColor="#436EEE"
android:centerColor="#4876FF" />
</shape>

Android: Round Image inside ring shape

I want to create a button with image inside it as shown at the bottom of this pic https://trianglewiki.org/RGreenway_App/_files/android.jpg/_info/. I am trying using layer-list and shape drawables and able to create buttons very similar. My problem is that my image is not scaling inside the button as I would like. The ring shape is coming on the top of the image but image is not inside it.
I want the image to be completely inside the ring. I think there is something wrong with the parameters values I am giving. But it could be I am not doing it the proper way.
Can somebody check my xml files and see what is the problem or provide me with any information how to do it so that I get the same effect in the button as in the link above. Thanks

You are overcomplicating this is if I understand your question. Look to here for an answer. It's the trick I have used in the past.
