A custom recycler view with shimmer views to indicate that views are loading. The recycler view has a built-in adapter to control the shimmer appearance and provide two methods -

  • showShimmerAdapter() - set up a demo adapter a predefined number of child demo views.
  • hideShimmerAdapter() - restores your adapter to show the actual child elements.

Demo Screen

There are two kinds of shimmer animation which you can see here:

  1. This type of shimmer effect uses the whole ViewHolder item to animate on.
List Demo Grid Demo
  1. Here the shimmer effect only applied on for those views which background color is nontransparent.
List Demo Grid Demo

Shimmer effect types

  1. As you can see the first demo examples show that the whole ViewHolder item is animated. To achieve the desired effect, the children of the ShimmerLayout should have a nontransparent background.

  2. You can achieve the second kind of shimmer effect by adding only one ViewGroup child to the ShimmerLayout with a transparent background. This ViewGroup will have the other views with nontransparent backgrounds on which the effect will be seen.

    You may wonder how can you add background to the root view of the ViewHolder, if you do not have direct access to the ShimmerLayout and the only child has a nontransparent background. The solution for this is to use the shimmer_demo_view_holder_item_background attribute.
