Android Spinner Inside RecyclerView Get Current View When Selected

Question

I have a RecyclerView implementing a LinearLayout of CardViews through an adapter. Inside each CardView, I have a spinner. What I need to do is get the CardViews position when a spinner is selected. Ex.. if I have 10 CardViews in a list on the screen with a spinner in each, and a select a value from the spinner in the 5th item, I need to get that 5th position as well as the selected value.

I'm able to get the selected value just fine. The issue is with getting the CardViews position. The CardViews are being generated from an ArrayList.

I will include my code below along with an image of the desired results. Any help is greatly appreciated!!

RecyclerView Adapter

public class PopularAdapter extends RecyclerView.Adapter<PopularAdapter.MyViewHolder> {

    PopularFragment mPopularFragment;
    private Context mContext;
    private ArrayList<GameData> gameDataArr = new ArrayList<GameData>();
    private String userId;

    public PopularAdapter(Context context, ArrayList<GameData> gameDataArr, PopularFragment mPopularFragment, String userId) {
        mContext = context;
        this.gameDataArr = gameDataArr;
        this.mPopularFragment = mPopularFragment;
        this.userId = userId;
    }

    public class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        public TextView title;

Solution

You can set an OnClickListener on mGameSpinner in your onBindViewHolder().

onBindViewHolder(final PopularAdapter.MyViewHolder holder, final int position)

You can then store/use the position parameter as it will be the index into your gameArray for that particular spinner. You can then use that index to grab the spinner's currently selected value and do whatever you need to do with it.

This works with an OnItemSelectedListener. Thanks for the help!

[karthik kolanji]

OnItemSelectedListener gives position of the spinner values , but what about position of recyclerview ?

[karthik kolanji]

YOU cannot set OnClickListener to spinner

[MarkInTheDark]

@karthikkolanji Why not? I'm pretty sure I was able to back when I posted my answer and it worked fine. Granted, it is not the optimal way as I have realized since then. So what do you mean?

[karthik kolanji]

I tried ... It throws error ." You cannot set OnClickListener() to spinner"
