Recyclerview ViewHolder不可单击-android

RecyclerView Viewholder单击不起作用。我正在为recyclerview使用LinearLayoutManager。recyclerview viewholder内未触发clcik事件。我错过什么了吗？这是我的取景器

 public class FeedViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
            @Bind(R.id.imgNewUser)  CircularImageView imgUser;
            @Bind(R.id.txtUserNameNewUser)  TextView txtUserNameNewUser;
            @Bind(R.id.txtNewUserPostCount)  TextView txtNewUserPostCount;
            @Bind(R.id.btnFollowNewUser)  Button btnFollowNewUser;
            public FeedViewHolder(View view) {
                super(view);
                view.setOnClickListener(this);
                ButterKnife.bind(this,view);
            }
            @Override
            public void onClick(View v){
                Toast.makeText(mContext,"Hello",Toast.LENGTH_SHORT);
                onFollowListener.onFollow(getAdapterPosition());
            }
        }

以及膨胀的行布局
