Get AlertDialog title by findViewById

Question

I tried to change AlertDialog font by used this function

private void saveDialog(){

    AlertDialog.Builder builder = new AlertDialog.Builder(this); 
        builder.setTitle(res.getString(R.string.dialog_title))
               .setMessage(res.getString(R.string.dialog_saveconfirm)) 
               .setCancelable(false)
               .setNegativeButton(res.getString(R.string.dialog_cancel), new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    dialog.cancel();
                 }
               })
               .setPositiveButton(res.getString(R.string.dialog_ok), new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    //do some thing
            });
        AlertDialog alert = builder.create();
        alert.show();

        TextView tit = (TextView) alert.findViewById(android.R.id.title);
        TextView msg = (TextView) alert.findViewById(android.R.id.message);
        Button btn2 = alert.getButton(DialogInterface.BUTTON_NEGATIVE);
        Button btn1 = alert.getButton(DialogInterface.BUTTON_POSITIVE);
        tit.setTypeface(UtiliShare.getTf());
        msg.setTypeface(UtiliShare.getTf());
        btn1.setTypeface(UtiliShare.getTf());
        btn2.setTypeface(UtiliShare.getTf());

}

When I call function in Activity I had 02-25 17:59:04.759: E/AndroidRuntime(1014): java.lang.NullPointerException for tit when set typeface but when I remove tit dialog work good.

I think error in TextView tit = (TextView) alert.findViewById(android.R.id.title); it is return null.

How can I solve this??

In order to alter textviews the way you want, I'd recommend using a custom layout for dialogs. Have a look at
