Where How to getIntent getExtras in an Android Fragment

Question

With Activities   I used to do this   In Activity 1   Intent i   new Intent getApplicationContext    MyFragmentActivity class                   i putExtra  name   items get arg2                    i putExtra  category   Category                   startActivity i     In Activity 2   Item   getIntent   getExtras   getString  name      How do you do this using Fragments   I am using the compatibility library v4 also   Does it go in the FragmentActivity   Or the actual Fragment  And Which Method does it go in   onCreate  onCreateView  another   And can I see example code please   EDIT   It is worth noting I am trying to keep Activity 1 as an Activity  or actually ListActivity where I am passing the intent of the listitem when clicked  and then pass to a set of tabbed-fragments  through a Fragment Activity  and I need either tab to be able to get the extras   I hope this is possible

you can still use   String Item   getIntent   getExtras   getString  name      in the fragment  you just need call getActivity   first    String Item   getActivity   getIntent   getExtras   getString  name      This saves you having to write some code

What I tend to do  and I believe this is what Google intended for developers to do too  is to still get the extras from an Intent in an Activity and then pass any extra data to fragments by instantiating them with arguments   There s actually an example on the Android dev blog that illustrates this concept  and you ll see this in several of the API demos too  Although this specific example is given for API 3 0  fragments  the same flow applies when using FragmentActivity and Fragment from the support library   You first retrieve the intent extras as usual in your activity and pass them on as arguments to the fragment   public static class DetailsActivity extends FragmentActivity         Override     protected void onCreate Bundle savedInstanceState            super onCreate savedInstanceState                omitted some other stuff           if  savedInstanceState    null                   During initial setup  plug in the details fragment              DetailsFragment details   new DetailsFragment                details setArguments getIntent   getExtras                 getSupportFragmentManager   beginTransaction   add                      android R id content  details  commit                        In stead of directly invoking the constructor  it s probably easier to use a static method that plugs the arguments into the fragment for you  Such a method is often called newInstance in the examples given by Google  There actually is a newInstance method in DetailsFragment  so I m unsure why it isn t used in the snippet above     Anyways  all extras provided as argument upon creating the fragment  will be available by calling getArguments    Since this returns a Bundle  its usage is similar to that of the extras in an Activity   public static class DetailsFragment extends Fragment                  Create a new instance of DetailsFragment  initialized to        show the text at  index               public static DetailsFragment newInstance int index            DetailsFragment f   new DetailsFragment                Supply index input as an argument          Bundle args   new Bundle            args putInt  index   index           f setArguments args            return f             public int getShownIndex             return getArguments   getInt  index   0                  other stuff omitted
