Question

I have multiple classes, which all extend some BasicDataModel:

public class NewsItem extends BasicDataModel
public class PhotosItem extends BasicDataModel

etc. So I need to make ArrayAdapters for all of them, and I wonder if it is possible to make some generic ArrayAdapter to fit all my objects. So far I tried to make

public class MyAdapter extends ArrayAdapter<BasicDataModel> 

but as long as I pass ArrayList, for example, this doesn’t work.

Thanks in advance

Answer 1

Try

public class MyAdapter<T extends BasicDataModel> extends ArrayAdapter<T>

and use

MyAdapter<NewsItem> news;
