How to add stroke to just bottom side of Material button?

Question

I want to achieve this button.

I Tried to add layer-list drawable background.

• Doesn't work in case of MaterialButton.
• In case of normal button it also doesn't work because My AppTheme is Material Theme. So normal Button also behaves like Material Button.

You can't use MaterialButton for a custom drawable Background like this, said in it's documentation:

Do not use the android:background attribute. MaterialButton manages its own background drawable, and setting a new background means MaterialButton can no longer guarantee that the new attributes it introduces will function properly. If the default background is changed, MaterialButton cannot guarantee well-defined behavior.

Anyways, I designed the custom Background drawable for a normal Androidx Button for you.

In your activity_main.xml you define the Button with the attribute android:background="@drawable/custom_shape" you will insert the drawable we define later:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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"
    tools:context=".MainActivity"
    android:layout_margin="10dp">

    <androidx.appcompat.widget.AppCompatButton
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Collect"
        android:background="@drawable/custom_shape"
        android:textColor="#ffffff"/>

</RelativeLayout>

Here is the mentioned drawable called custom_shape.xml:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item>
        <shape android:shape="rectangle">
            <solid android:color="#ffc9a1"/>
            <corners android:radius="10dp"/>
        </shape>
    </item>

    <item android:bottom="5dp">
        <shape>
            <solid android:color="#f7791e" />
            <corners android:radius="10dp"/>
        </shape>
    </item>
</layer-list>

The final result look pretty close to your wished Button:
