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
