It seems that .margin or margin has no use.

Yes, I also find this issue for multi view type.

@csumissu
I just checked my sample and it works well.
In my sample, ComplexActivity shows margin implementation. Please check ComplexAdapter.
If you cannot solve the problem, please show me your implementation.

I use your library as this:
mRecyclerView.addItemDecoration(new HorizontalDividerItemDecoration.Builder(getContext())
.colorResId(R.color.whiteSmoke)
.sizeResId(R.dimen.divider)
.marginResId(R.dimen.tile_divider_margin)
.build());

but it does not work.
I check the ComplexAdapter you mentioned, it seems the same.

Please check it. Thank you!

I have the same problem,it does not work about margin, I use like this:
mRecyclerView.addItemDecoration(new HorizontalDividerItemDecoration.Builder(mContext)
.paintProvider(mQuickAdapter)
.visibilityProvider(mQuickAdapter)
.marginProvider(mQuickAdapter)
.build());

in my adapter:
@OverRide
public int dividerLeftMargin(int position, RecyclerView parent) {
return 50;
}

@Override
public int dividerRightMargin(int position, RecyclerView parent) {
    return 0;
}

the LeftMargin does not work well
