Updating UI after dialog dismissed

Question

I have activity A which have a ListView with custom adapter.

The custom adapter (which aplies to each list view item) have a button which invokes a custom dialog.

in this dialog an action is being performed which in response i want to invoke UI update on activity A.

This is my activity on resume code:

@Override
public void onResume() 
{
    super.onResume();
    setUI();  
}

But when the i call

dialog.dismiss();

The dialog closes without the Activity A OnResume method benig invoked.

How can i catch and update the activity ui?

You can set an OnDismissListener to your dialog to achieve this:

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setOnDismissListener(listener);
...
Dialog dialog = builder.create();

You can let your Activity impelement DialogInterface.OnDismissListener and set them as the listener, so they get notified in the method onDismiss(DialogInterface dialog). In there, you can update your UI.
