RecyclerView item onClick

RecyclerView does not have an OnItemClickListener like it's predecessor, ListView. However, detecting item clicks is pretty simple.

Set an OnClickListener in your ViewHolder creation:

private class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder>  {

    public static class ViewHolder extends RecyclerView.ViewHolder
            implements View.OnClickListener {
        private String mItem;
        private TextView mTextView;

        public ViewHolder(View view) {
            super(view);
            view.setOnClickListener(this);
            mTextView = (TextView) view;
        }

        public void setItem(String item) {
            mItem = item;
            mTextView.setText(item);
        }

        @Override
        public void onClick(View view) {
            Log.d(TAG, "onClick " + getPosition() + " " + mItem);
        }
    }

    private String[] mDataset;

    public MyAdapter(String[] dataset) {
        mDataset = dataset;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View v = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.list_item, parent, false);
        ViewHolder vh = new ViewHolder(v);
        return vh;
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        holder.setItem(mDataset[position]);
    }

    @Override
    public int getItemCount() {
        return mDataset.length;
    }
}

Add touch feedback to your item layout:

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceListItemSmall"
    android:gravity="center_vertical"
    android:paddingStart="?android:attr/listPreferredItemPaddingStart"
    android:paddingEnd="?android:attr/listPreferredItemPaddingEnd"
    android:minHeight="?android:attr/listPreferredItemHeightSmall"
    android:background="?android:attr/selectableItemBackground"
/>

the base class doesn't have any on click method???

but can use int item instead of String item and it's easier work with items

getPosition is deprecated, use getAdapterPosition instead.

thanks, this save me from item clicklistener mess.
Though this is what i use...
int itemPosition = getLayoutPosition();
Products products = productsArrayList.get(itemPosition);
Thanks for the clue

👍 👍 👍 👍

Thanks! This is by far the cleanest solution I have seen for this. Helped a lot!

Short and concise. Thanks!

I use this method

Thanks

thanks for the code, you saved my lot of time.

how to get startactivity in onclick()

v.getContext().startActivity(activityIntent);

how to implement onItemClickListener on individual items/icons of viewHolder in a recyclerView and perform actions on them inside fragment/activity, but not inside the adapter

You should not couple your ViewHolders and ItemClickListeners. Please see a better solution here.

how is this better? You don't need a gesture detector to handle clicks.

Just set a setOnClickListener(). The original gist is significantly better than what you linked.
