Button.java

public class Button extends android.widget.Button {
    public Button(@NonNull Context context) {
        super(context, null, R.style.My_Button);
        init(context, null);
    }

    public Button(@NonNull Context context, @Nullable AttributeSet attrs) {
        super(context, attrs, R.style.My_Button);
        init(context, attrs);
    }
    public Button(@NonNull Context context, @Nullable AttributeSet attrs, @AttrRes int defStyleAttr) {
        super(context, attrs, R.style.My_Button);
        init(context, attrs);
    }
    // ... more
}

styles.xml

<style name="My_Button" parent="Base.Widget.AppCompat.Button.Borderless">
    <item name="android:foreground">?android:attr/selectableItemBackground</item>
    <item name="android:background">#592612</item>
    <item name="android:gravity">center</item>
</style>

Answer 1

Finally, I have found the answer!

Replace:

super(context, attrs, R.style.My_Button); with super(context, attrs, R.attr.ButtonStyle);

In styles.xml add

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="ButtonStyle">@style/Button_Style</item>
    ...
</style>

In attrs.xml add

<declare-styleable name="Theme">
    <attr name="ButtonStyle" format="reference"/>
</declare-styleable>
