java - RecyclerView in Fragment -

i setting recyclerview inside fragment following android docs example here.

i pasted code below, there not much. (the difference i'm using fragment instead of activity).

the error i'm getting is:

java.lang.illegalstateexception: specified child has parent. must call removeview() on child's parent first.

all solutions problem online add false argument in layout inflation fragment. i've done this, , still error.

my code:

mainactivity

... mfragmentmanager = getsupportfragmentmanager(); mfragmenttransaction = mfragmentmanager.begintransaction(); mfragmenttransaction.replace(r.id.containerview,new newsfragment()).commit(); ... 

newsfragment

public class newsfragment extends fragment {      private recyclerview mrecyclerview;     private recyclerview.adapter madapter;     private recyclerview.layoutmanager mlayoutmanager;      @nullable     @override     public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {         view v =  inflater.inflate(r.layout.news_layout,container, false);          mrecyclerview = (recyclerview) v.findviewbyid(r.id.my_recycler_view);         mrecyclerview.sethasfixedsize(true);          mlayoutmanager = new linearlayoutmanager(getactivity());         mrecyclerview.setlayoutmanager(mlayoutmanager);          madapter = new newsadapter(new string[]{"hello","world","qwert","test","greg","peck"});         mrecyclerview.setadapter(madapter);          return v;      } } 

newsadapter

public class newsadapter extends recyclerview.adapter<newsadapter.viewholder> {     private string[] mdataset;      public static class viewholder extends recyclerview.viewholder {         public textview mtextview;          public viewholder(textview tv) {             super(tv);             mtextview = tv;         }     }      public newsadapter(string[] mydataset) {         mdataset = mydataset;     }      @override     public newsadapter.viewholder oncreateviewholder(viewgroup parent,                                                    int viewtype) {         view v = layoutinflater.from(parent.getcontext())                 .inflate(r.layout.news_item, parent, false);          textview tv = (textview)v.findviewbyid(r.id.textview2);         viewholder vh = new viewholder(tv);         return vh;     }      @override     public void onbindviewholder(viewholder holder, int position) {         holder.mtextview.settext(mdataset[position]);     }      @override     public int getitemcount() {         return mdataset.length;     } } 

any hugely appreciated!

the error on line:

textview tv = (textview)v.findviewbyid(r.id.textview2); viewholder vh = new viewholder(tv); 

change to:

textview tv = (textview)v.findviewbyid(r.id.textview2); viewholder vh = new viewholder(v); 

the text view having parent. that's why getting error.

updated code:

public class newsadapter extends recyclerview.adapter<newsadapter.viewholder> {     private string[] mdataset;      public static class viewholder extends recyclerview.viewholder {         public textview mtextview;          public viewholder(view view) {             super(tv);            mtextview= (textview)view.findviewbyid(r.id.textview2);         }     }      public newsadapter(string[] mydataset) {         mdataset = mydataset;     }      @override     public newsadapter.viewholder oncreateviewholder(viewgroup parent,                                                    int viewtype) {         view v = layoutinflater.from(parent.getcontext())                 .inflate(r.layout.news_item, parent, false);           viewholder vh = new viewholder(v);         return vh;     }      @override     public void onbindviewholder(viewholder holder, int position) {         holder.mtextview.settext(mdataset[position]);     }      @override     public int getitemcount() {         return mdataset.length;     } }
