    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);

    context = getApplicationContext();

    recyclerView = (RecyclerView) findViewById(R.id.recycler_view1);


    recyclerViewLayoutManager = new GridLayoutManager(context, 2);

    recyclerView.setLayoutManager(recyclerViewLayoutManager);

    recyclerView_Adapter = new RecyclerViewAdapter(context,numbers);

@Override
public RecyclerViewAdapter.ViewHolder 
onCreateViewHolder(ViewGroup parent, int viewType){

    View view1 = LayoutInflater.from(context1).inflate
 (R.layout.recycler_view_items,parent,false);

    ViewHolder viewHolder1 = new ViewHolder(view1);

    return viewHolder1;
}

@Override
public void onBindViewHolder(ViewHolder Vholder, int position){

    Vholder.textView.setText(values[position]);

    Vholder.textView.setBackgroundColor(Color.CYAN);

    Vholder.textView.setTextColor(Color.BLUE);

}

@Override
public int getItemCount(){

    return values.length;
}
}

share some more code - your background, your adapter, don't expect us to checkout a project form a link in the question in order to help you — Ognian Gloushkov, Nov 10 '16 at 09:53
so when you set the background on the recycler_view_items nothing happens ? — Ognian Gloushkov, Nov 10 '16 at 10:04
That background will be shown in each item but i need this background for each row. — Om Bala, Nov 10 '16 at 10:23

Easy Hack : U can use LinearLayout manager instead of gridLayoutManager. Then u can change item layout (layout for each item in adpater ie:recycler_view_items) to

something like this

<LinearLayout
 background: set it as ur image>
   <LinearLayout>
    // first item 
   </LinearLayout>

   <LinearLayout>
     //2nd item
   </LinearLayout>

<LinearLayout>

and change adapter to set values accordingly. It requires changing layout and adapter codes. This will work for u as u can set background for each row

(PS: Each row is now considered as a single item)

Thanks buddy but i need to use gridlayoutmanager because i am showing items in grid only .. In Grid view , i have show each row with same image.. – Om Bala Nov 10 '16 at 11:41
grid layout will not help u achieve this .adapter uses each object separately to draw items. u will not get access to each row inside adapter – Victor Nov 10 '16 at 11:51
OK, Thank You Vicky :) – Om Bala Nov 14 '16 at 05:24
