This gallery is used to align photos with different aspect ratios in a fluid way. It tries to keep the aspect ratio of the photos and reduce the crop as much as possible.

Download via Gradle:

• Add the following to the project's build.gralde

allprojects {
    repositories {
       jcenter()
    }
}

• Add this to your dependencies

compile 'com.abed.android:flexiimagegallery:1.0.0'

• Configurable spacing between the items:

With Spacing	Without Spacing

• Configurable row height:

Small Height (more dense)	Bigger Height (less dense)

• Add the FlexiGallery to the xml layout file

    <com.abed.flexiimagegallery.ui.view.FlexiGallery
        android:id="@+id/flexi_gallery"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        xmlns:app="http:https://schemas.android.com/apk/res-auto"
        app:gallery_items_vertical_spacing="10dp"
        app:gallery_items_horizontal_spacing="10dp"
        app:gallery_average_row_height="400dp"/>

The FlexiGallery has 3 paramters to specify:

• gallery_items_horizontal_spacing: (optional. Default 0dp) It specifies the dimension of the horizontal spacing between the photos.
• gallery_items_vertical_spacing: (optional. Default 0dp) It specifies the dimension of the vertical spacing between the photos.
• gallery_average_row_height: (optional) This tells the library what is the desired row height and the library will optimize the algorithm to arrange the items in a way were the row height is as close as possible to what you specified.

Inside your java code you specify the rest of the parameters that are needed for the gallery to get rendered and function:

• The photos to be presented using the function "configure". Where you pass a list of the object "GalleryPhoto"
• The ImageLoader used. This is a hook to let you use whichever image loading library you like (Picasso, Glide, Universal Image Loader)
• The PhotoClickListener (Optional) in case you want to have click event listener on the photos

  List<GalleryPhoto> galleryPhotos 
    .
    .
    
  flexi_gallery.configure(galleryPhotos, new ImageLoader() {
    @Override
    public void loadImage(String url, ImageView imageView) {
      Glide.with(imageView.getContext()).load(url).into(imageView);
    }
  });
  
  flexi_gallery.setPhotoClickListener(new FlexiGalleryAdapter.PhotoClickListener() {
    @Override
    public void onPhotoClick(View view, int position, GalleryPhoto photo) {
      Toast.makeText(view.getContext(), position + "", Toast.LENGTH_SHORT).show();
    }
  });
