RecyclerViewDivider

A RecyclerView's divider that can be customized with simple properties or advanced ones.

It supports completely LinearLayoutManager, GridLayoutManager and partially StaggeredGridLayoutManager.

Usage

If you want to use the basic version of this divider you can just add this line of code after your setAdapter() method:

RecyclerViewDivider.with(context).build().addTo(recyclerView);

Customization

All dividers in the app have default values in xml resources:

Color → R.color.recycler_view_divider_color (default is #CFCFCF)
Size → R.dimen.recycler_view_divider_size (default is 1dp)
Margin size → R.dimen.recycler_view_divider_margin_size (default is 0dp)

It can be customized in code with properties equals for each divider:

color(int) → change color
drawable(Drawable) → change drawable
tint(int) → change drawables' tint
size(int) → change height for an horizontal divider, width for a vertical one
marginSize(int) → change left/right margin for an horizontal divider, top/bottom for a vertical one

Example with all general properties set:

RecyclerViewDivider.with(context)
                .color(color)
                // OR
                .drawable(drawable)
                .tint(tint)
                .size(size)
                .marginSize(marginSize)
                .hideLastDivider()
                .build()
                .addTo(recyclerView);

It can also use custom factories to have a different logic for each divider:

visibilityFactory(VisibilityFactory) → set visibility
drawableFactory(DrawableFactory) → set color/drawable
tintFactory(TintFactory) → set tint
sizeFactory(SizeFactory) → set size
marginFactory(MarginFactory) → set margin

Example with all factories set:

RecyclerViewDivider.with(context)
                .visibilityFactory(new VisibilityFactory() {
                    @Override
                    public int displayDividerForItem(int groupCount, int groupIndex) {
                        if (groupCount % groupIndex == 0) {
                            return SHOW_ITEMS_ONLY;
                        }
                        return SHOW_ALL;
                    }
                })
                .drawableFactory(new DrawableFactory() {
                    @Override
                    public Drawable drawableForItem(int groupCount, int groupIndex) {
                        return position % 2 == 0 ? new ColorDrawable(Color.BLACK) : new ColorDrawable(Color.BLUE);
                    }
                })
                .tintFactory(new TintFactory() {
                    @Override
                    public int tintForItem(int groupCount, int groupIndex) {
                        return position == 0 ? Color.YELLOW : Color.GRAY;
                    }
                })
                .sizeFactory(new SizeFactory() {
                    @Override
                    public int sizeForItem(@Nullable Drawable drawable, int orientation, int groupCount, int groupIndex) {
                        return position % 2 == 0 ? 45 : 78;
                    }
                })
                .marginFactory(new MarginFactory() {
                    @Override
                    public int marginSizeForItem(int groupCount, int groupIndex) {
                        return position % 2 == 0 ? 10 : 10 * 2;
                    }
                })
                .build()
                .addTo(recyclerView);

You can also use this divider as a simple space between RecyclerView's items:

Example of divider as space:

RecyclerViewDivider.with(context).asSpace().build().addTo(recyclerView);
