I have got two activities. In first you can input jobname and job place into inputtext views. First activity contains also navigation-draver menu (appearing from left side of screen). After clicking "Searc" button, results are shown in listview in second activity. You can long-click on any listview item and then it will be added to navigation-drawer in first activity. You can go back to first activity by clicking "back" arrow. The problem is, that when I will go back to first activity, press "Search" button again and then go back to first activity again, the navigation drawer menu is empty again (all items, which were added on first try are deleted). How to fix that?
Here is pic with my activities (sorry for poor quality):
1- first activity; 2- navigation drawer in first activity with added items from second activity' listview; 3- second activity (listview with search results)
EDIT: My code from two activities (without imports to shorten it a little): First (main):
