Get positive Button in DialogPreference

Question

Is there a way to get the positive button of a DialogPreference in any of its events?

I would like to disable it initially, and make it enabled once a EditText validates.

Simply call

 (AlertDialog)dialog.getButton(AlertDialog.BUTTON_POSITIVE).setEnabled(false);

If you are using a Dialog Builder though, make sure you call this after builder.create() and before .show()

You can then keep a reference to the dialog and enable the button once your conditions are fulfilled.

Yes, this is correct. getDialog() is working in showDialog, which I override. Thanks for your help. – Bridget the Midget Jun 07 '12 at 14:51

AlertDialog dialog = (AlertDialog) getDialog(); Button ok = dialog.getButton(AlertDialog.BUTTON_POSITIVE); ok.setEnabled(false); – slinden77 Dec 22 '13 at 17:20

It worked only after BOTH `builder.create()` and `show()` method executed. Before `show()` return was null. – corochann Mar 09 '16 at 08:00

@corochann is correct, the button if null is you have show() after. Guykun's code is otherwise correct. – Lara Ruffle Coles Apr 27 '16 at 20:37
Is there any way to override showDialog with android.support.v7.preference.DialogPreference? – Touré Holder Nov 05 '17 at 11:49
