android drawable - RecyclerView ItemDecoration -

i trying create itemdecoration drawn divider between recyclerview items left padding.

currently have implementation inside itemdecoration class:

@override public void ondrawover(canvas c, recyclerview parent, recyclerview.state state) {     final int left = parent.getpaddingleft();     final int right = parent.getwidth() - parent.getpaddingright();     final recyclerview.layoutmanager lm = parent.getlayoutmanager();     final int childcount = parent.getchildcount();      (int = 0; < childcount; i++) {         final view child = parent.getchildat(i);         recyclerview.viewholder viewholder = parent.getchildviewholder(child);          final int top = lm.getdecoratedbottom(child);         final int bottom = top + mdivider.getintrinsicheight();         mdivider.setbounds(left + 40, top, right, bottom);         mdivider.draw(c);     } } 

but seems divider still drawing full width. doing wrong?

i tried setting insetdrawable left insets (from xml), divider, seems not draw @ all.

ps. 40 value hardcoded one, explanatory purpose. mdivider drawable.

tip:

for add left padding:

@override public void getitemoffsets(rect outrect, view view, recyclerview parent, recyclerview.state state) {     outrect.left = 30; }
