Passing data RecyclerView data to another activity on click
Question
I am currently in the process of passing information from my recyclerview to another activity called "partyInformation", in respective to the clicked cell. The information in my recyclerView is fetched from parse.com. My recyclerview consists of textviews as well as imageViews and I would like to populate my "partyInfomation" with this data. When I compile and run I receive no errors but when a cell is clicked from my recyclerview my app quits and reads "Unfortunately, app has stopped". The logcat prompts the error: java.lang.ClassCastException: android.support.v7.widget.AppCompatTextView cannot be cast to android.os.Parcelable.
Can you please review my code and help identify where I went wrong in the process of trying to pass data on click?

Change this:
i.putExtra("partyName", (Parcelable) partyNameText);
i.putExtra("promoterNameText", (android.os.Parcelable) promoterNameText);
i.putExtra("costText", (android.os.Parcelable) costText)
To this:
i.putExtra("partyName", partyNameText.getText().toString());
i.putExtra("promoterNameText", promoterNameText.getText().toString()));
i.putExtra("costText", costText.getText().toString()))
This adds data to intent 'i' as Strings. You can't cast from a TextView to a Parcelable.
