ScrollGalleryView is a flexible library which helps you to create awesome media galleries in your Android application. It's easily integrated with the most popular image loading libraries such as Picasso, Glide and Fresco.

• Easy way to select images in gallery (thumbnails)
• Zooming
• Simple API
• Video

Add JitPack repository to your root build.gradle (see more details here):

allprojects {
    repositories {
        // ...
        maven { url 'https://jitpack.io' }
    }
}

Add dependency to your module build.gradle:

implementation 'com.veinhorn.scrollgalleryview:library:1.2.6'

There are several MediaLoaders implementations for most popular caching libraries: Picasso, Glide, Fresco.

implementation 'com.veinhorn.scrollgalleryview:picasso-loader:1.2.4'

implementation 'com.veinhorn.scrollgalleryview:glide-loader:1.2.9'

implementation 'com.veinhorn.scrollgalleryview:fresco-loader:1.2.4'

Add ScrollGalleryView to your layout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <com.veinhorn.scrollgalleryview.ScrollGalleryView
        android:id="@+id/scroll_gallery_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#000"/>
</LinearLayout>

Initialize ScrollGalleryView in your activity:

import static com.veinhorn.scrollgalleryview.loader.picasso.dsl.DSL.*; // simplifies adding media

public class MainActivity extends FragmentActivity {
    private ScrollGalleryView galleryView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        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.

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).

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

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

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