Question

We have two AlertDialog objects

AlertDialog dialog1, dialog2;

both dialogs are created via AlertDialog.Builder.
How can we recognize which dialog is source of event in DialogInterface.OnClickListener ?

with single dialog we can do this:

AlertDialogInstance.setOnClickListener(myListener);

//myListener
public void onClick(DialogInterface arg0, int arg1) {
        switch (arg1) {
            case AlertDialog.BUTTON_NEGATIVE:
                // do something
                break;
            case AlertDialog.BUTTON_POSITIVE:
                // do something
                break;
            case AlertDialog.BUTTON_NEUTRAL:
                // do something
                break;
        }
    }

how to modify this switch logic to handle multiple dialogs?
(Or if there is better system to handle dialogs, other than inline button callbacks, what is it?)

Answer 1

I’ll recommend you to put needed param in the custom listener.

private class CustomOnClickListener implements OnClickListener {
    private int id;

    public CustomOnClickListener(int id) {
       this.id = id;
    }

    public void onClick(DialogInterface dialog, int which) {
            //check id and which
        }

}

Then, when you add onClickListeners to dialogs, you just provide an id to listener.
