You can use Intents.

You have to launch your 2nd Activity with a startActivityForResult (Intent intent, int requestCode). Then before terminating it you must put the data that you wish to add to the 1st Activity in an Intent.

Finally, in your first Activity, you get this data in the onActivityResult() method.

Here's a detailled example: http://developer.android.com/resources/tutorials/notepad/notepad-ex2.html

you should use startActivityForResult(for start SelectorActivity) in current activity(lets call it ListActivity) then in second activity (lets call it SelectorActivity) you have to put some confirm button(OK) and when you click OK button you should call setResult and finish SelectorActivity

back in ListActivity you should override onActivityResult and add data from SelectorActivity to list Adapter

first look here http://developer.android.com/reference/android/app/Activity.html#StartingActivities

Edit: you should return data in Intent ... use Intent.putExtra() in setResult and then Intent.getExtra() in onActivityResult
