Why does button text not showing in bydefault center in MaterialComponents?

Question

When I was using AppCompat this thing was working fine, but when I changed to MaterialComponents, it looks bad.

See the current image:

See the 'W' it is not showing properly. for 'H' Also same problem.

Note: I tried using Button, AndroidXbutton and MaterialButton, nothing is working in MateriaComponents case.

Code:

<androidx.cardview.widget.CardView
            android:id="@+id/circle_card_payment"
            android:layout_width="40dp"
            android:layout_height="40dp"
            android:elevation="12dp"
            android:innerRadius="0dp"
            android:shape="ring"
            android:thicknessRatio="1.9"
            app:cardCornerRadius="20dp">

            <ImageView
                android:id="@+id/icon"
                android:layout_width="match_parent"
                android:layout_height="40dp"
                android:layout_alignParentTop="true"
                android:layout_centerHorizontal="true"
                android:visibility="gone"></ImageView>

            <com.google.android.material.button.MaterialButton
                android:id="@+id/logo"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentTop="true"
                android:layout_centerHorizontal="true"
                android:text="A"
                android:textColor="@color/colorWhite"
                android:textSize="16sp"
                android:visibility="gone"></com.google.android.material.button.MaterialButton>


        </androidx.cardview.widget.CardView>

I'm setting programatically drawable background, because in material components, it does not giving effect on XML.

logo.setBackgroundResource(R.drawable.bg_circle_btn);

bg_circle_btn.xml:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">

    <solid android:color="?attr/toolbar_color" />

    <size
        android:width="120dp"
        android:height="120dp" />
</shape>

Please note if I change cardview size 40dp to 50dp, this problem will solve, but size will be bigger that looks bad.

</LinearLayout>

Answer 1

In the MaterialButton you shouldn't use setBackground* methods.
You can check the logcat, you should find something like:

W/MaterialButton: Do not set the background; MaterialButton manages its own background drawable

Instead in the MaterialButton you can define a custom shape in different way. For example you can do:

<com.google.android.material.button.MaterialButton
            android:id="@+id/logo"
            android:layout_width="48dp"
            android:layout_height="48dp"
            android:text="W"
            android:padding="0dp"
            app:strokeWidth="0dp"
            android:insetLeft="0dp"
            android:insetTop="0dp"
            android:insetRight="0dp"
            android:insetBottom="0dp"
            android:textColor="#FFFFFF"
            android:textSize="16sp"
            app:shapeAppearanceOverlay="@style/ShapeAppearanceOverlay_ButtonCircle50"
            />

where the ShapeAppearanceOverlay_ButtonCircle50 is defined by:

  <style name="ShapeAppearanceOverlay_ButtonCircle50">
    <item name="cornerFamily">rounded</item>
    <item name="cornerSize">50%</item>
  </style>
