How to create interface between Fragment and adapter?

by

Make a new constructor and an instance variable:

AdapterInterface buttonListener;

public MyListAdapter (Context context, Cursor c, int flags, AdapterInterface buttonListener)
{
  super(context,c,flags);
  this.buttonListener = buttonListener;
}

When the Adapter is made, the instance variable will be given the proper reference to hold.

To call the Fragment from the click:

public void onClick(View v) {
   buttonListener.buttonPressed();
}

When making the Adapter, you will have to also pass your Fragment off to the Adapter. For example

MyListAdapter adapter = new MyListAdapter (getActivity(), myCursor, myFlags, this);

since this will refer to your Fragment, which is now an AdapterInterface.

Keep in mind that on orientation of the Fragment changes, it will most likely be recreated. If your Adapter isn’t recreated, it can potentially keep a reference to a nonexistent object, causing errors.
