Add dependency

dependencies {
   compile 'com.dinuscxj:recycleritemdecoration:1.0.0'
}

Set HeaderItemDecoration

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

SetShaderItemDecoration

//simple usage
ShaderItemDecoration shaderItemDecoration = new ShaderItemDecoration(getActivity(),
                    ShaderItemDecoration.SHADER_BOTTOM
                    | ShaderItemDecoration.SHADER_TOP
                    | 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() {
    @Override
    public Shader createShader(RecyclerView parent) {
        return null;
    }
});

    new LinearDividerItemDecoration.DrawableCreator() {
        @Override
        public Drawable create(RecyclerView parent, int adapterPosition) {

        }
    }

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

//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) {
            return getResources().getDrawable(R.drawable.bg_animal_divider);
        }
    }
);

Set GridOffsetsItemDecoration

//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;
        }
        @Override
        public int createHorizontal(RecyclerView parent, int adapterPosition) {
            return 30;
        }
    }
);
offsetsItemDecoration.setOffsetEdge(true);
