Android material lib ShapeableImageView is not showing preview with app:shapeAppearanceOverlay

Question

There is a problem using ShapeableImageView material component and set shapeAppearanceOverlay to make it a circle image. It doesn't show up in viewport. Seems like we set the visibility to GONE. However, it shows perfectly on the device.

Is there any way to fix it? or since it is still in 1.2.0-alpha05 so under development or a known bug?

Answer 1

Try this,

style.xml :

<resources>
    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar">
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

   <!-- ShapeableImageView theme. (note that the parent matches the Base App theme) -->
    <style name="ShapeAppearance.ImageView" parent="Theme.MaterialComponents.Light.DarkActionBar">
        <item name="cornerFamily">rounded</item>
        <item name="cornerSize">50%</item>
    </style>

</resources>

my_layout.xml :

<com.google.android.material.imageview.ShapeableImageView
        android:id="@+id/sivAdvImage"
        android:layout_width="0dp"
        android:layout_height="150dp"
        android:src="@drawable/test_image"
        android:scaleType="centerCrop"
        app:shapeAppearance="@style/ShapeAppearance.ImageView"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

works with: com.google.android.material:material:1.3.0-alpha03
