How to catch the result of an intent in Listview's CustomListAdapter class in android

Question

I have an ArrayList which has objects of type Person. Person class has fields name, address1, address2, city, state, postcode and country. I want to be able to edit a particular person and then update the changes such that the ListAdapter which displays the Persons shows updated data. This ListView is contained in RecipientActivity (Activity A)

In the custom Adapter I start the Activity RecipientAddressActivity (Activity B) using an intent in the TextView's onClick event:

holder.txtRecName.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {               
            Intent rec_Intent = new Intent(context,
                                        RecipientAddressActivity.class);
            rec_Intent.putExtra("Current_Recipient",
                                         recipientArray.get(index));
            rec_Intent.putExtra("RecipientIndex",index);
            context.startActivity(rec_Intent);          

        }
    }); 

In the Activity B I get the Current_Recipient and the index in onCreate() event like this:

current_rec = (Person) getIntent().getSerializableExtra(
            "Current_Recipient");
Recipient_Index = getIntent().getIntExtra("RecipientIndex", 151);

In the same activity, I have a button "Save" and on its Onclick I create a Person object which can be either a new Person or an old person being edited.

Button Save's onClick() event

{
  Intent Recipient_info = new Intent();
  Person recipient = new Person(edt_rec_name.getText().toString(),
   edt_rec_addr1.getText().toString(),edt_rec_addr2.getText().toString(),
   edt_rec_city.getText().toString(), edt_rec_state.getText().toString(),
   edt_rec_pcode.getText().toString(), edt_rec_country.getText().toString()); 
   Recipient_info.putExtra("Person", recipient);
   Recipient_info.putExtra("RecipientIndex", Recipient_Index);
   setResult(RESULT_OK, Recipient_info);
   finish();
}

The problem is there are 2 ways of starting Activity B. I don't know where or how to catch the result when Actvity B is started using ListView's Adapter.

Please help me asap. Kindly let me know if some more code or explanation is required.

Thanks.

I have noticed that in your code:

you are not starting activity as activityForResult.
