 }

Set HeaderItemDecoration

java
 PinnedHeaderDecoration pinnedHeaderDecoration = new PinnedHeaderDecoration();
 pinnedHeaderDecoration.registerTypePinnedHeader(getItemViewType(ItemTitle.class),
     new PinnedHeaderDecoration.PinnedHeaderCreator() {
         @Override
         public boolean create(RecyclerView parent, int adapterPosition) {
             return true;
         }
     }
 );

SetShaderItemDecoration

java
 //simple usage
 ShaderItemDecoration shaderItemDecoration = new ShaderItemDecoration(getActivity(),
                     ShaderItemDecoration.SHADER_BOTTOM

                     | ShaderItemDecoration.SHADER_RIGHT
                     | ShaderItemDecoration.SHADER_LEFT);
 shaderItemDecoration.setShaderTopDistance(shaderTopDistance);
 shaderItemDecoration.setShaderBottomDistance(shaderBottomDistance);
 //complex usage
 ShaderItemDecoration shaderItemDecoration = new ShaderItemDecoration(getActivity(),
                     ShaderItemDecoration.SHADER_BOTTOM | ShaderItemDecoration.SHADER_TOP);
 shaderItemDecoration.registerBottomShaderCreator(new ShaderItemDecoration.ShaderCreator() {

     public Shader createShader(RecyclerView parent) {
         return null;

 });

Set LinearDividerItemDecoration

                     getActivity(), LinearDividerItemDecoration.LINEAR_DIVIDER_VERTICAL);
 dividerItemDecoration.setDivider(divider);
 //complex usage
 LinearDividerItemDecoration dividerItemDecoration = new LinearDividerItemDecoration(
                     getActivity(), LinearDividerItemDecoration.LINEAR_DIVIDER_VERTICAL);
 dividerItemDecoration.registerTypeDrawable(getItemViewType(ItemAnimal.class),
     new LinearDividerItemDecoration.DrawableCreator() {
         @Override
         public Drawable create(RecyclerView parent, int adapterPosition) {
             return getResources().getDrawable(R.drawable.bg_animal_divider);
         }
     }
 );

Set LinearOffsetsItemDecoration

java
 //simple usage
 LinearOffsetsItemDecoration offsetsItemDecoration = new LinearOffsetItemDecoration(
                       LinearOffsetItemDecoration.LINEAR_OFFSETS_HORIZONTAL);
 offsetsItemDecoration.setItemOffsets(itemOffsets);
 //complex usage
 LinearOffsetsItemDecoration offsetsItemDecoration = new LinearOffsetItemDecoration(
                     LinearOffsetItemDecoration.LINEAR_OFFSETS_HORIZONTAL);
 offsetsItemDecoration.registerTypeOffset(getItemViewType(ItemAnimal.class),
     new LinearOffsetItemDecoration.OffsetsCreator() {
         @Override
         public int create(RecyclerView parent, int adapterPosition) {
             return 30;
         }
     }
 );
 offsetsItemDecoration.setOffsetEdge(true);
 offsetsItemDecoration.setOffsetLast(true);

Set GridDividerItemDecoration

java
 //simple usage
 GridDividerItemDecoration dividerItemDecoration = new GridDividerItemDecoration(getActivity(),
                     GridDividerItemDecoration.GRID_DIVIDER_VERTICAL);
 dividerItemDecoration.setVerticalDivider(verticalDivider);
 dividerItemDecoration.setHorizontalDivider(horizontalDivider);
 //complex usage
 GridDividerItemDecoration dividerItemDecoration = new GridDividerItemDecoration(getActivity(),
                     GridDividerItemDecoration.GRID_DIVIDER_VERTICAL);
 dividerItemDecoration.registerTypeDrawable(getItemViewType(ItemAnimal.class),
     new GridDividerItemDecoration.DrawableCreator() {
         @Override
         public Drawable createVertical(RecyclerView parent, int adapterPosition) {
             return getResources().getDrawable(R.drawable.bg_animal_divider);
         }
         @Override
         public Drawable createHorizontal(RecyclerView parent, int adapterPosition) {

         }
     }
 );

Set GridOffsetsItemDecoration

java
 //simple usage
 GridOffsetsItemDecoration offsetsItemDecoration = new GridOffsetsItemDecoration(
                     GridOffsetsItemDecoration.GRID_OFFSETS_HORIZONTAL);
 offsetsItemDecoration.setVerticalItemOffsets(verticalItemOffsets);
 offsetsItemDecoration.setHorizontalItemOffsets(horizontalItemOffsets);
 //complex usage
 GridOffsetsItemDecoration offsetsItemDecoration = new GridOffsetsItemDecoration(
                     GridOffsetsItemDecoration.GRID_OFFSETS_HORIZONTAL);
 offsetsItemDecoration.registerTypeDrawable(getItemViewType(ItemAnimal.class),
     new GridOffsetsItemDecoration.OffsetsCreator() {
         @Override
         public int createVertical(RecyclerView parent, int adapterPosition) {
             return 30;
         }
