Question

I’m new to Android. I have two activities. First activity shows selected contact list from second activity. Second activity shows contact list from database with checkbox. Now I can read a contact list from database and shows at checkbox. Therefore I don’t know how to pass selected contacts from first to second activity and how to display selected contact list. Is there any easy way to do it?

Thank you for every advice and guide.

Thanks,
Zeck.

1. First you have to get Data from your database
   then create a CursorAdapter or any Adapter you want and
   fill it with data and override getView() there.
   Here http://developer.android.com/reference/android/widget/SimpleCursorAdapter.html
   and here http://thinkandroid.wordpress.com/2010/01/09/simplecursoradapters-and-listviews/

2. Set your adapter into a ListView then
   implement onclicklistener on this ListView
   where you will pass the data to Bundle and start a new Activity

listView onclick goes to a new activity
Here

and here

There’re many other ways how to share the data between activities
like SharedPreferences or Sqlite database. But it’s not the topic for this answer.
