Hi, I have solved the re adding by clearing the list items first - see code below. For the fragment that i want to add i have added the following image - on each sliding tab i have a different list view. When i click an item on the list view i want to show a different fragment that has in it some controls (all fragments will have a Start/Stop button in common). Next step will be to have the first item in each list selected when the tab is changed so that i will have the associated fragment shown .
