Question

I have this simple code:

AlertDialog dialog = new AlertDialog.Builder(this).create();

dialog.setTitle ("Alert title");
dialog.setMessage ("This is an alert");

dialog.show();

The dialog is shown but my Activity receives no callbacks. No onPrepareDialog, nothing.

Can I somehow hook AlertDialog without implementing a custom class extending AlertDialog?

Thanks.

Answer 1

onPrepareDialog is only called for dialogs managed by an Activity (i.e. dialogs created and returned with Activity.onCreateDialog(int) and shown via Activity.showDialog(int)). Since you are creating and showing a dialog directly, these methods will not be called.

See Creating Dialogs for more information on managed dialogs.

To respond to use input – like button clicks – you’ll want to use the builder methods as demonstrated by alezhka’s answer.
