You can use a MaterialCardView and apply a ShapeAppearanceModel.

Something like:

  TriangleEdgeTreatment edgeTreatment = new TriangleEdgeTreatment(getResources().getDimension(R.dimen.cutout_size),true);

  cardView.setShapeAppearanceModel(cardView.getShapeAppearanceModel()
      .toBuilder()
      .setTopEdge(edgeTreatment)
      .build());
