MainActivity Method displayAddEditFragment
Method displayAddEditFragment
(Fig. 8.20) receives a View
’s resource ID specifying where to attach the AddEditFragment
and a Bundle
of key–value pairs. If the second argument is null
, a new contact is being added; otherwise, the Bundle
contains the data to display in the AddEditFragment
for editing. Line 105 creates the AddEditFragment
. If the Bundle
argument is not null
, line 108 uses it to set the Fragment
’s arguments. Lines 111–115 then create the FragmentTransaction
, replace the contents of the View
with the specified resource ID, add the Fragment
to the back stack and commit the transaction.
