//Create a Card, set the title over the image and set the thumbnail
CustomMaterialLargeImageCard card = (CustomMaterialLargeImageCard)
        CustomMaterialLargeImageCard.with(getActivity())
                .setTextOverImage("Italian Beaches "+i)
                .setTitle("This is my favorite local beach "+i)
                .setSubTitle("A wonderful place")
                .useDrawableId(R.drawable.sea)
                .setupSupplementalActions(R.layout.carddemo_native_material_supplemental_actions_large, actions)
                //It is important to use this build method
                .build(new CustomMaterialLargeImageCard(getActivity()));
                
    class CustomMaterialLargeImageCard extends MaterialLargeImageCard {

        public CustomMaterialLargeImageCard(Context context) {
            super(context);
        }

        @Override
        protected MaterialLargeImageCardThumbnail initializeCardThumbnail() {
            //Init your custom Thumbnail
            return new CustomMaterialThumbnail(mContext);
        }
    }

    class CustomMaterialThumbnail extends MaterialLargeImageCardThumbnail{

        public CustomMaterialThumbnail(Context context) {
            super(context);
        }

        @Override
        public void setupInnerViewElements(ViewGroup parent, View imageView) {
            //Call the super method
            super.setupInnerViewElements(parent, imageView);
            
            //Your code here
            mTitleOverImageView = (TextView) parent.findViewById(default_text_id);
            mTitleOverImageView.setTextColor(Color.RED);
        }
    }
