I am using a ListFragment and a Detail Fragment. The example from Android Studio uses tag for the list view. But i already have a ListView in a LinearLayout. can i use that or should it have a fragment tag. If not, then what is the advantage of using fragment tag.
Best How To :
When you use
<fragment ..> tag in xml layout of your
Activity, your Fragment is automatically committed by
FragmentManager, but you should either specify a tag (which is a
String) or id (which is primitive
int) when declaring it:
<fragment android:id="@+id/my_fragment" ...>
<fragment android:tag="mytag" ..>
Fragment must have an unique identifier so that it can be re-associated with a previous instance upon
Activity recreation (on configuration change, resuming after pressing home button, etc).
For example, it is useful to have an id or tag when performing calls to:
FragmentManager.findFragmentById(int id);//fragment id or its container id
