    Please use an interface like below, pass it in the adapter's constructor, and than use it in your activity / Fragment

       public MyAdapter(Context context, List data, MyAdapterListener myAdapterListener) {
             this.context = context;
             this.data = data;
              this.myAdapterListener = myAdapterListener;
        }

        public interface MyAdapterListener {

    void onContainerClick(View view, int position); 
    }

     }

    public class ViewHolderItem extends RecyclerView.ViewHolder implements View.OnClickListener {
        public LinearLayout container;

        public ImageView poster;

        public ViewHolderItem(View v) {
            super(v);

            container = (LinearLayout) v.findViewById(R.id.container);

            poster = (ImageView) v.findViewById(R.id.poster);

            container =setOnClickListener(this); /// this line must include
        }

        @Override
        public void onClick(View v) {
            int id = v.getId();

            if (id == R.id.container) {
               if (myAdapterListener != null) {
    myAdapterListener.onContainerClick(v,getAdapterPosition());
                }
            }
        }
    }



    Use it like this in your fragment/Activity
    


    mAdapter = new MyAdapter(getApplicationContext() , data, new MyAdapter.MyAdapterListener() {
                    @Override
                    public void onContainerClick(View v, int position) {
                        Log.d(TAG, "iconTextViewOnClick at position "+position);
                    }

                });
mRecycler.setAdapter(mAdapter);
