Android RecyclerView update Adapter -

i've got recyclerview adapter. tried set adapter programmatically, doesnt work.

here's code:

public class recordadapter extends recyclerview.adapter<recordviewholder>{      private list<recorddata> records;      public recordadapter(){         records = new arraylist<>();     }      @override     public recordviewholder oncreateviewholder(viewgroup parent, int viewtype) {         flog.d("records: creating new recordviewholder");         view view = layoutinflater.from(parent.getcontext()).inflate(r.layout.record_item, parent, false);         return new recordviewholder(view);     }      @override     public void onbindviewholder(recordviewholder holder, int position) {         recorddata data = records.get(position);         flog.d("records: binding new recordviewholder");          holder.mrecordtext.settext("record " + position);     }      @override     public int getitemcount() {         flog.d("records: count - " + records.size());         return records.size();     }      public void addrecord(recorddata newrecord){         records.add(newrecord);         this.notifydatasetchanged();     } } 

my recordviewholder is:

public class recordviewholder extends recyclerview.viewholder{  @bind(r.id.record_play_button) public imagebutton mrecordplay;  @bind(r.id.record_message_text) public textview mrecordtext;  @bind(r.id.record_seek_bar) public seekbar mseekbar;   public recordviewholder(view itemview){     super(itemview);     butterknife.bind(this, itemview); } 

i've tried set adapter this:

if (adapter == null){     adapter = new recordadapter(); }  adapter.addrecord(recorddata); holder.mincomingrecordlist.setadapter(adapter); 

but adapter didnt call methoda oncreateviewholder , onbindviewholder

my xml file recyclerview:

<linearlayout xmlns:a="http://schemas.android.com/apk/res/android"             a:orientation="vertical"             a:layout_width="wrap_content"             a:layout_height="wrap_content">      <linearlayout         a:layout_width="wrap_content"         a:layout_height="wrap_content">  .......          <linearlayout             a:layout_width="wrap_content"             a:layout_height="wrap_content">                 <android.support.v7.widget.recyclerview                       a:layout_width="match_parent"                       a:layout_height="match_parent"                       a:id="@+id/record_list"/>         </linearlayout>    </linearlayout> </linearlayout>
