Slidenerd makes some great videos, he helped me a lot as well when I started.

You might want to reconsider what you're trying to do and approach it differently... Why would you want to pass 3 textview from your UI into a dialog? This is going to be painful.

Seems like you're going to have to extend DialogFragment (i'm assuming that's what you're using for a dialog, maybe an alert?). Create a static factory method inside the DialogFragment like this...

public class MyDialog extends DialogFragment {

    private static tv1, tv2, tv3;

    public static MyDialog newInstance(TextView tv1, TextView tv2, TextView tv3){
       MyDialog.tv1 = tv1;
       MyDialog.tv2 = tv2;
       MyDialog.tv3 = tv3;
       return new MyDialog();
    }
}

Once you have this complete, create this dialog fragment inside that onClick method in the ViewHolder class. Instantiate the DialogFragment by doing this...

MyDialog.newInstance(title,email,itemId).show(getFragmentManager(),"dialog_tag");

Like i said before, it's seems sloppy and is probably error prone. There may be a better way of doing this but this is all I can think of off the top of my head. Let me know how it works out for you.. or perhaps revise your question so we can better help you reach a better solution to what you're trying to do.
