I made an example, but I'm not quite happy with it. https://drive.google.com/file/d/0B5FlDY ... sp=sharing
I saved the settings of two different ListViews as a JSON. First with Item1,2,3 second with Item4,5,6. The problem is, you save not only the items in it, you save the whole settings of the ListView. So you have set the position of the ListView after loading the JSON or you have to put the ListViews from where you save your datas, on the position where they should be, like I have.
Maybe there is a better solution with arrays and a loop.
