Started from v28 design support library we can use Material Card View, which provides us with a material styled cardview implementation out of the box.
<android.support.design.card.MaterialCardView
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_margin="10dp">
... child views ...
</android.support.design.card.MaterialCardView>
You can further style the cardview by using two of the attributes that come with it:
- app:strokeColor – The colour to be used for the given stroke, this must be set in order to display a stroke
- app:strokeWidth – The width to be applied to the stroke of the view
