        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        galleryView = ScrollGalleryView
                .from((ScrollGalleryView) findViewById(R.id.scroll_gallery_view))
                .settings(
                        GallerySettings
                                .from(getSupportFragmentManager())
                                .thumbnailSize(100)
                                .enableZoom(true)
                                .build()
                )
                .add(image("http://pirate-islands.com/wp-content/uploads/2018/07/07_Dom-Fernando-II_01-636x310.jpg"))
                .add(image("http://povodu.ru/wp-content/uploads/2016/04/pochemu-korabl-derzitsa-na-vode.jpg"))
                .add(video("http://www.sample-videos.com/video/mp4/720/big_buck_bunny_720p_1mb.mp4", R.mipmap.default_video))
                .build();
    }
}

If you use ScrollGalleryView version prior 1.2.0 or need more info about gallery initialization you can find it here.

Adding media

ScrollGalleryView supports different types of media such as images and videos. You can create image gallery, video gallery, or mix them in any way. To abstract from concreate way of image loading ScrollGalleryView uses MediaLoader so it makes possible to use different image loading libraries depending on your needs (Picasso, Glide, Fresco).

Picasso loader

Default image loader

Library is also contains default image loader but it's not optimized for performance.

Note: it's highly recommended to use custom image loader against default

Configuration

You can specify a bunch of additional settings during gallery initialization.

Adding listeners

ScrollGalleryView supports adding listeners for events like: image click, long image click, changed page. More details you can find in separate doc.
