How to assign target fragment not in fragment class?

Question

Android

I have an adapter for an ExpandableList, it makes a listView on a TaskList fragment, and in the adapter, when the child is clicked, a new TaskDialog fragment opens.
I need to target a TaskList for a TaskDialog!
If this is done in the fragment class, then there are no problems, but when I do it in the adapter class, an error occurs!

TaskDialog taskDialog = TaskDialog.newInstance(name);
        taskDialog.setTargetFragment(TaskList.class, REQUEST_ADD_TASK_CODE);
        taskDialog.show(context.getSupportFragmentManager(), TASK_DIALOG_FLAG);

Is it possible to do this in a class that is not a fragment?

Answer 1

setTargetFragment() takes an instance of the Fragment class as input, and you push the class to it. Of course, this cannot be done, you need to transfer a specific object. From what class it will be made (from a fragment, adapter, etc.) - all the same.
