alert dialog in android should not dismiss

Question

I am making an application and it has an Alert Dialog in it.

Now i am checking some data I got from AlertDialog editTexts in dialog Positive button OnClick method but the dialog always dismiss if data i got from edittext fields is correct or not.

How can we disable this feature.

UPDATED:

I am gettin Pin Code and Confirm Pin Code from the Dialog Box and in onPositive click i have checked to verify the pin codes.

Now if the pin codes matches then it is calling dialog.dismiss() and if not matching then display a Toast.

But in case of pin code not matched it displays me the message and dismiss the dialog.

I dont want that to be happen.

MORE UPDATES:

is there any way that i will disable the OK Button and when data is verified it will enable the positive Button??

Please help

This is the trick (override onClickListener inside onShowListener):

final AlertDialog d = new AlertDialog.Builder(context)
                .setView(v)
                .setTitle(R.string.my_title)
                .setPositiveButton(android.R.string.ok,
                        new Dialog.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface d, int which) {
                                //Do nothing here. We override the onclick
                            }
                        })
                .setNegativeButton(android.R.string.cancel, null)
                .create();

        d.setOnShowListener(new DialogInterface.OnShowListener() {

            @Override
            public void onShow(DialogInterface dialog) {

                Button b = d.getButton(AlertDialog.BUTTON_POSITIVE);
                b.setOnClickListener(new View.OnClickListener() {

                    @Override
                    public void onClick(View view) {
                        // TODO Do something

                        //Dismiss once everything is OK.
                        d.dismiss();
                    }
                });
            }
        });
