Question

Here’s the code for my ItemAdapter which I use as an adapter for list in this way.

list.setAdapter(new ItemAdapter(thisContext,imageUrl));

I’m trying to implement an onclick listener for the button that will add an item to a ListFragment. When I compile, it says “cannot resolve symbol getSupportFragmentManager”. See bold below. But I’m pretty sure I imported android.support.v4.app.FragmentActivity (see below).
I used the same getSupportFragmentManager in my main activity and it works. I don’t understand why it isn’t here. And if it isn’t, how should I obtain the HeadlinesFragment so that I can add to the list in that fragment?

Appreciate any help I can get here.

It’s been a while since I played around with fragments. but I believe you can only access getSupportedFragmentManager from an FragmentActivity class.

try this

public ItemAdapter(Context c,FragmentActivity activity, String[] imageUrl)
{
   super();
   itemPageContext = c;
   this.activity = activity;
   imagesUrl = imageUrl.clone();  // copy over
}

then within the class extending FragmentActivity do this:

list.setAdapter(new ItemAdapter(thisContext,thisActivity, imageUrl));

then within the Adapter do this

activity.getSupportedFragmentManager...

Hope this helps
