    Button b1,b2;
    public Offline_Adapter(Context context, ArrayList<Offers> datas) {

        this.context = context;
        this.datas = datas;
        selectedItems = new SparseBooleanArray();
        mRequestQueue = Volley.newRequestQueue(context);
        mImageLoader = new ImageLoader(mRequestQueue, new ImageLoader.ImageCache() {

            private final LruCache<String, Bitmap> mCache = new LruCache<String, Bitmap>(10);

            public void putBitmap(String url, Bitmap bitmap) {
                mCache.put(url, bitmap);
            }

            public Bitmap getBitmap(String url) {

public class Offline_ViewHolder extends RecyclerView.ViewHolder {
    NetworkImageView image;
    TextView title;
    TextView tv1,v_count,c_count,f_count;
    Offline_Adapter adapter;
    public Offline_ViewHolder(View itemView) {
        super(itemView);
        image=(NetworkImageView)itemView.findViewById(R.id.img_thumbnail);
        title=(TextView)itemView.findViewById(R.id.name);
        v_count= (TextView) itemView.findViewById(R.id.viewcount_txt);

recyclerview with button

Answer 1

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
       if(position==0){
         youbutton.setOnclickListener();
       }else{
       }
    }

use position in onBindViewHolder.

Answer 2

You are doing wrong here

@Override
    public Offline_ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        b1=(Button)findViewById(R.id.b1);
        b2=(Button)findViewById(R.id.b2);

And why are you doing this stuff in onCreateViewHolder() of RecyclerView Adapter class. From your code it seems these buttons are in Activity or Fragment layouts. Right? If yes, please find them in Activity fragment and set Click Listener to them.

Next: make a public method in Adapter class and a state variable in Adapter class too.

    public class Offline_Adapter extends RecyclerView.Adapter<Offline_ViewHolder> {
         Context context;
private boolean mIsOfflineMode = false;

        RequestQueue mRequestQueue;
        ImageLoader mImageLoader;
        DBHelper myDB;
        ArrayList<Offers> datas;

and public method in adapter as

   public void setOfflineSate(boolean state){
     mIsOfflineMode  = state;
 this.notifyDataSetChanged();
    }

Next: Now time comes to handle view in onCreateViewHolder method of adapter.

   @Override
    public Offline_ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View view ;
        if(isOffileMode){
        view = LayoutInflater.from(v.getContext()).inflate(R.layout.offline_data_card, null);     
    }else{
     view=LayoutInflater.from(v.getContext()).inflate(R.layout.offline_data_card_view2,null);
    }

     Offline_ViewHolder ovh=new Offline_ViewHolder(view);
        return ovh;
   }

Now in your activity or fragment class, handle button click as

 // I am supposing you have Offline_Adapter Object as mOffLineAdapter and is  initialized 
 b1=(Button)parent.findViewById(R.id.b1);
        b2=(Button)parent.findViewById(R.id.b2);

        b1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
             mOffLineAdapter.setOfflineSate(false);
            }
        });
        b2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
               mOffLineAdapter.setOfflineSate(true);
            }
        });
