Here's an example of an alert dialog with OK and Cancel Button:

AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(getActivity());

alertDialogBuilder.setTitle("Your Tile");

alertDialogBuilder
    .setMessage("Your Message")
    .setCancelable(false)
    .setPositiveButton("Ok",new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog,int id) {
        // OK Button

        }
        })
    .setNeutralButton("Cancel",new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog,int id) {
             dialog.cancel();   
                }
        });

AlertDialog alertDialog = alertDialogBuilder.create();
alertDialog.show();

you have a problem with the code, please have a look alertDialogBuilder.show();

instead of this line please use

AlertDialog alertDialog = alertDialogBuilder.create();


                alertDialog.show();

AlertDialog alertDialog = alertDialogBuilder.create();
