I have an activity that needs to display Android phone contacts into a ListView which is a fragment inside my AddressBook.java activity. I was able to get my list to display the names, but nothing else. I feel like I am close, but having a hard time with getting the views to work. In my XML files (I have 4), I have the activity XML (only has the fragment), the ListView XML (contact_list_view.xml), and then a typical row for the ListView which I call my Item XML (contacts_list_item.xml). But how do I connect all those views into my activity view? I think I have the fragment inside of the activity OK, since the list of names works, but not sure how to get a photo and email to display. I know I'm missing something in my main code too, ContactFragments.java.
One issue, is I had to filter my contacts by name, otherwise every email in every application on my phone would post, which is not what I want. I only want the contacts in my Android Contacts app to display, so I hope that doesn't inhibit the other details of the contacts from showing.
Below is my code, I don't show my AddressBook.java activity, because I only use the XML view to display my fragment in it, using the fragment tags (which works fine, because I do at least get the contact names).
I have searched far and wide for answers to this online, but there are so many parts, I could not find how to address my specific situation. I hope to use my code I already have and edit it minimally (versus implementing a whole new way to achieve this with other classes, etc). If you have any ideas, I'd be very thankful.
