Can't you not turn it off when you click the button in the dialog?

final AlertDialog d = new AlertDialog.Builder(context)
        .setView(v)
        .setTitle(R.string.my_title)
        .setPositiveButton(android.R.string.ok, null) //onClick. Please make it null.
        .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) {
                            // giving a condition

                            // If the input value is good, dialog is off
                d.dismiss();
            }
        });
    }
});
