I am making a todo app. I made a shared preference to save the data to internal storage an an arryadapter to manage my data. Everything works well. I added a strikethrough functionality and it works, but when I exit and reopen the app the strikethrough is gone and I don't know how to restrike through the todos in my listview.I can populate my listview with the data I extracted from my shared preferences. It shows but it does not strikethrough.When I tried to access listview getchild, I get a null exception
