Get id of specific item clicked in RecyclerView

Question

I am passing position and view in my OnItemClicked(int position, View v) method of OnItemClickListener interface. Now in my ViewReceptionistActivity I want to check which item and which sub part is clicked. If the user clicks an image then perform task A els if user clicks name perform task B and so on..

Here is my layout file - viewreceptionist_item.xml

<?xml version="1.0" encoding="utf-8"?>

                        if(position != RecyclerView.NO_POSITION)

                }
            });
        }
    }
}

Here is ViewReceptionistActivity

                    receptionistsList.add(receptionist);

                    viewReceptionistAdapter.notifyDataSetChanged();

//HERE I WANT TO CHECK IF USER CLICKS AN IMAGE OR NAME OR EMAIL...
//IF USER CLICKS IMAGE - PERFORM TASK A
//IF USSER CLICKS NAME - PERFORM TASK B...AND SO ON


            }
        });

        LinearLayoutManager manager = new LinearLayoutManager(getApplicationContext(), LinearLayoutManager.VERTICAL, false);


        recyclerView.setLayoutManager(manager);
        recyclerView.setAdapter(viewReceptionistAdapter);

    }
}

I want to get the specific item clicked from the view...

Yup, that method works fine.. But its too lengthy if we have 5-6 views in a recycler view item.But i am trying if we are passing the view along with the position in the method then we must have an method to get an item from that view so that we can work on that instead of setting on click listener again and again.. I have also tried by passing itemView from holder but nothing happened.. — Raj, May 15 '18 at 13:46
There's no way of detecting clicks without using click listener. You won't be able to check if a subview was clicked just by detecting a click in the parent view. — Levi Moreira, May 15 '18 at 14:21

You're better off extending your click interface with methods for each view you want to add a reaction to a click event:

public interface OnItemClickListener
    {
        void OnItemImageClicked(int position, View v);
        void OnItemNameClicked(int position, View v);
    }

And in your viewHolder:

viewReceptionistImage.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v)
                {
                    if(listener != null)
                    {
                        int position = getAdapterPosition();

                        if(position != RecyclerView.NO_POSITION)
                        {
                            listener.OnItemImageClicked(position, v);
                        }
                    }

                }
            });


tvViewReceptionistName.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v)
                {
                    if(listener != null)
                    {
                        int position = getAdapterPosition();

                        if(position != RecyclerView.NO_POSITION)
                        {
                            listener.OnItemNameClicked(position, v);
                        }
                    }

                }
            });

Then in your ViewReceptionistActivity you simply implement the interface and override the methods (as they will be many). Then you set the listener in your adapter like so:

viewReceptionistAdapter.setOnItemClickListener(this);

Or you can use the old way:

viewReceptionistAdapter.setOnItemClickListener(new ViewReceptionistAdapter.OnItemClickListener() {
            @Override
            public void OnItemImageClicked(int position, View v)
            {
             Toast.makeText(ViewReceptionistActivity.this, "You Clicked " + position + "Image View: " + v, Toast.LENGTH_SHORT).show();

            }

            @Override
            public void OnItemNameClicked(int position, View v)
            {
              Toast.makeText(ViewReceptionistActivity.this, "You Clicked " + position + " TextView: " + v, Toast.LENGTH_SHORT).show();

            }
        });
