Android Lists and Adapters Lists with RecyclerViews Creating a RecycleView ViewHolder Challenge

Link to Challenge: http://teamtreehouse.com/library/android-lists-and-adapters/lists-with-recyclerviews/creating-a-recyclerview-viewholder

The first two parts of the challenge are not too bad and

you can generally figure out the needed code for the first two parts of the challenge

Challenge Task 1 of 3

The class below is for a RecyclerView adapter. We need to add a view holder! Create a nested class called GameViewHolder. Make it public and have it extend RecyclerView.ViewHolder. Leave the rest blank for now.

Challenge Task 2 of 3

Next, add one member variable to your new view holder: a public TextView named mTitleLabel.

The last part of the challenge is tricky because of the way the question reads:

if you watch the video (many many times):

https://teamtreehouse.com/library/android-lists-and-adapters/lists-with-recyclerviews/custom-adapters-and-viewholder-in-recyclerviews

For the last challenge, though..

Challenge Task 3 of 3

Finally, add a constructor for GameViewHolder that takes a View as its one parameter. Set mTitleLabel using the ID R.id.titleLabel.

...based on a strict reading of the question,

you may be tempted to use code like this:

  /* Add your code here */
  public class GameViewHolder extends RecyclerView.ViewHolder {
        public TextView mTitleLabel;

        public GameViewHolder(View) {
          mTitleLabel = View.findViewById(R.id.titleLabel);
        }
    }

Unfortunately this will not pass task 3 of 3.

What is needed?

Here is the forum thread that gave me the clue:

https://teamtreehouse.com/forum/call-getter-method-in-adapter-class

..which has this code:

        public ListItemViewHolder (View itemView){
            super(itemView);
            nameView = (TextView) itemView.findViewById(R.id.name);
            adresseView = (TextView) itemView.findViewById(R.id.adresse);
            typView = (TextView) itemView.findViewById(R.id.typ);
            bewertungView = (TextView) itemView.findViewById(R.id.bewertung);
            itemView.setOnClickListener(this);
        } // end constructor

        @Override
        public void onClick (View v) {
            Intent intent = new Intent(sContext,ActivityDetail.class);
            // HERE I WANT TO COMMIT MY DATA
            sContext.startActivity(intent);
        }

Notice the 'View itemView' parameter.

This is what is given in the video about time mark 4:07.

Notice the 'View v' parameter.

This is what is needed to pass the challenge.

If the question had read:

Finally, add a constructor for GameViewHolder that takes a 'View v' as its one parameter.

..that would have been a lot more helpful (and less confusing).

Because changing the setting of the paramter also causes this line

mTitleLabel = View.findViewById(R.id.titleLabel);

..to change to this line:

mTitleLabel = v.findViewById(R.id.titleLabel);

Maybe this was blindingly obvious to most people,

to the ones for who it was not

hopefully this forum post clues them in to what the question was really asking for..

(without giving the whole code answer).
