Define your my_demo_view.xml and refer the layout reference here. | 26 | |```app:demo_layout_manager_type``` | ```setDemoLayoutManager(LayoutManagerType)``` | Layout manager of demo view. Can be one among linear_veritical or linear_horizontal or grid. | 27 | 28 | 29 | 30 | Usage 31 | -------- 32 | 33 | Define your xml as: 34 | 35 | ```xml 36 | 37 | 46 | 47 | ``` 48 | where ```@layout/layout_demo_grid``` refers to your sample layout that should be shown during loading spinner. Now on your activity onCreate, initialize the shimmer as below: 49 | 50 | ```java 51 | ShimmerRecyclerView shimmerRecycler = (ShimmerRecyclerView) findViewById(R.id.recycler_view_contacts); 52 | shimmerRecycler.showShimmerAdapter();
