Question

I need help working on this generics code.

protected AbsPageAdapter getAdapter() {
    return new NewsPageAdapter<>(getSupportFragmentManager(), getConfigs());  // error
}

@Override
protected List<? extends Configuration> getConfigs() {
    return new ConfigHelper(this).getNewsConfigs();
}

public NewsPageAdapter(FragmentManager fm, List<T> objects) {
    super(fm, objects);
}

Here's the errors:

Not sure how to fix this

Answer 1

Provide the type of the objects held by getConfigs() to the instance of NewsPageAdapter, for example

return new NewsPageAdapter<SomeConfig>(getSupportFragmentManager(), getConfigs());

Or it is whatever type defined in class NewsPageAdapter when you instantiate NewsPageAdapter in that line
