Here are the background details of my app:
- Using a FragmentPagerAdapter in my main activity to show couple of different fragments.
- For one of my fragments, I am using a ListView that is populated by a custom ArrayAdapter that is using a custom object class, in this case "Deal".
- Using an ArrayList passed into the custom ArrayAdapter.
What I basically am stuck on: when I click any "deal" on the ListView fragment page, I want to go to another activity and pass in the info from the specific Deal object. So, if I click Deal 1, I want to pass in the Deal 1 object to the new activity for it's info. If I click on Deal 2, I want to pass in the Deal 2 object to the new activity for it's info. I am unsure what to put in the onItemClickListener.
Please note, the ArrayList will get it's object from an external source later, just adding in the test subjects for now. Will I need to use the ArrayAdapter to pass in the information to the new activity page?
