hello i am having trouble working with this i am a beginner in android and java i want to pull out contact name information and place them inside a string array MyName then use the inflater to map each contact name to a textfield in the xml file i also have a toggle button and an image that i would like to use separately for each row how can i do that? and how can i fix this code where the at the class MyAdapter is not accessible and is stating that it is undeclared and the setListAdapter creationg function is showing an error

The type Main.MyAdapter is not generic; it cannot be parameterized with arguments <String>
