android - Can't catch touch event of Child View of Header of Sticky Header (RecyclerView) by eowise -

i'm using library "recyclerview-stickyheaders" link here : https://github.com/eowise/recyclerview-stickyheaders ok, can't catch touch event .setonheaderclicklistener(this) use stickyheadersbuilder class. can't , don't know how implement click listener child view of "header" ( textview, button in header ), in case btnfollow. catch touch event whole "header". try implement click listener class viewholder of header on ( headeradapter ) doesn't work. * in mainactivity :

protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);     recyclerview = (recyclerview) findviewbyid(r.id.rv_timeline);     adapterrecyclerview = new adapterrecyclertimeline(getapplicationcontext(), getdata());     adapterrecyclerview.setclicklistener(this);     recyclerview.setlayoutmanager(new linearlayoutmanager(getapplicationcontext()));     recyclerview.setitemanimator(new defaultitemanimator());     adapterheader = new adaptertimelineheader(getapplicationcontext(), getdata());     adapterheader.setclicklistener(this);     recyclerheader = new stickyheadersbuilder()             .setadapter(adapterrecyclerview)             .setrecyclerview(recyclerview)             .setstickyheadersadapter(adapterheader)             .setonheaderclicklistener(this)             .build();     recyclerview.setadapter(adapterrecyclerview);     recyclerview.additemdecoration(recyclerheader);  }  @override public void onheaderclick(view header, long headerid) {     toast.maketext(getapplicationcontext(), "header clicked lib", toast.length_short).show(); }  @override public void headerclicked(view view, int position) {     toast.maketext(getapplicationcontext(), "header clicked manual", toast.length_short).show(); } 

• in adapterheader

  public class viewholder extends recyclerview.viewholder implements view.onclicklistener{ relativelayout profile; textview tvprofilename; textview btnfollow;

  public viewholder(view itemview) {     super(itemview);     profile = (relativelayout) itemview.findviewbyid(r.id.profile);     tvprofilename = (textview) itemview.findviewbyid(r.id.tv_profile_name);     btnfollow = (textview) itemview.findviewbyid(r.id.btn_follow);     btnfollow.setonclicklistener(this);     l.m("set listener follow"); }  @override public void onclick(view v) {     if (clicklistener != null) {         l.m("do click follow");         clicklistener.headerclicked(v, getposition());     } } 

  } public interface clicklistener { public void headerclicked(view view, int position); }

  public void setclicklistener(clicklistener clicklistener) { this.clicklistener = clicklistener; }

• thank all!

this libraries not add view screen - copies pixel pixel view canvas. here code:

```

canvas.save(); canvas.translate(0, y); header.draw(canvas); canvas.restore(); 

```

so header not on screen - it`s visual clone.

it possible handle clicks on parent view - see library (it looks practically same)

but parent view extremely difficult send click event child (for example buttons in). , of course no animation because see not view.
