MainActivity Method onEditContact

Method onEditContact (Fig. 8.22) from the DetailsFragment.DetailsFragmentListener interface is called by the DetailsFragment to notify the MainActivity when the user touches the menu item to edit a contact. The DetailsFragment passes a Bundle containing the contact’s data so that it can be displayed in the AddEditFragment’s EditTexts for editing. If the layout contains the fragmentContainer, line 133 calls displayAddEditFragment to display the AddEditFragment in the fragmentContainer; otherwise, line 135 calls displayAddEditFragment to display the AddEditFragment in the rightPaneContainer.
