How to restrict input type in DialogAlert to alphanumeric?

Question

I've seen this other post but the top answer only works for TextViews defined in the manifest file, which is not my case. I'm using a DialogAlert object to ask for a String, which can only be alphanumeric.

[UPDATE]

    final EditText input = new EditText(MainActivityS.this);
    setUserIdAlertDialog.setView(input);
    setUserIdAlertDialog.setPositiveButton(getString(R.string.yesLabel), new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
            String value = input.getText().toString();
            Utils.sendStringIntent(getBaseContext(), getString(R.string.ACTION_ACTIVITY_NEW_ID), "ACTIVITY", value, getString(R.string.INTENT_EXTRA_NEW_USERNAME));
        }
    });



    setUserIdAlertDialog.setNegativeButton(getString(R.string.noLabel), new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
                                          }
                                    });
    setUserIdAlertDialog.show();

its not only for TextView it will work with EditText too http://stackoverflow.com/a/10929070/1012284 — Padma Kumar, Nov 20 '12 at 12:14
That only works when defining through the manifest file I think. I can't get it to work programatically. — Moises Jimenez, Nov 20 '12 at 12:35
are you asking how to restrict input type of an edittext programatically? — Andro Selva, Nov 20 '12 at 13:47
I know I can check each char or something like that, I also know there are a few input types in android (none of which are alphanumerical only), so yes, keeping those two exceptions in mind, I am asking that — Moises Jimenez, Nov 20 '12 at 14:15
