Question

i am using following code to start my activity

public void onClick(View v) {

                Intent myIntent = new Intent(v.getContext(), AddReceipt.class);

                startActivityForResult(myIntent, RECEIPT_ADDED);
            }

Now i want to get arrays from addreceipt class or data from my child activity

public synchronized void onActivityResult(final int requestCode, int resultCode, final Intent data) {

             if (resultCode == Activity.RESULT_OK) 
             {
                 if (requestCode == RECEIPT_ADDED)
                 {
                     String abc = "abs";
                 }
             }

         }

when calling this function, it returns data as null and result code as 0. How can i get my data from my child activity.

BesT Regards

Answer 1

To pass data from child activity to parent activity use the following code:

Intent intent= childActivity.getIntent();
intent.putExtra("key","value");  
childActivity.setResult(Activity.RESULT_OK, intent);
childActivity.finish();

if value is an list of object use Serializable .

Now if you press back button , onActivityResult method of parent class will be called and you will get RESULT_CANCEL.
