return value to fragment from activity android - android-activity

Question

I have Fragment(F) which calls the activity(A). On press of button(B) in activity(A) the activity must return selected arraylist value back to fragment(F) and finish activity(A)... is this possible?
I know from Activity you can send data with intent as:
Bundle bundle = new Bundle();
bundle.putString("key", "value");
// set Fragmentclass Arguments
Fragmentclass fragmentobj = new Fragmentclass();
fragmentobj.setArguments(bundle);
in Fragment onCreateView method:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
String strtext = getArguments().getString("key");
return inflater.inflate(R.layout.fragment, container, false);
}
but this works for calling new fragment not working with same fragment.
My question: is it possible for called Activity to return value to caller fragment?
public class HomeFragment extends Fragment{
Button attachment;
String strtext = "check";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.home_fragment, null);
attachment = (Button) rootView
.findViewById(R.id.btn_activity);
Toast.makeText(getActivity(),
"Key= " + strtext,
Toast.LENGTH_LONG).show();
attachment.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent myIntent = new Intent(getActivity(), AndroidCustomGalleryActivity.class);
getActivity().startActivityForResult(myIntent,999);
}
});
return rootView;
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == 999){
strtext = getArguments().getString("key");
Toast.makeText(getActivity(),
"Key= " + strtext,
Toast.LENGTH_LONG).show();
}
}
}
In Called Activity
Bundle bundle = new Bundle();
bundle.putString("key", "value");
HomeFragment fragmentobj = new HomeFragment();
fragmentobj.setArguments(bundle);
finish();

Answer 1

In your fragment(F) call the startActivityForResult() method to start the activity A, then override onActivityResult() method in the fragment.
So when the activity A finishes you can get get the result bundle in onActivityResult() method.
EDIT
In your fragment onClick() call the activity like this
Intent myIintent=new Intent(getActivity(), AndroidCustomGalleryActivity.class);
startActivityForResult(myIintent, 999);
And in your activity
Intent intent = getIntent();
Bundle bundle = new Bundle();
bundle.putString("key", "value");
intent.putExtras(bundle);
setResult(RESULT_OK, intent);
finish();
Now you will get the result in onActivityResult() method of the fragment.
EDIT2
In your fragment onActivityResult() method you have to get the data like this...
Bundle extras = data.getExtras();
strtext = extras.getString("key");
