如何在android中为StringTokenizer使用两个分隔符

大家好，我学习了如何在中使用两个分隔符 android中的StringTokenizer用于将空值存储到我拥有的db中 像这样的字符串，string1=IMPS 2223 9481851276 7654321，33

但使用stringtokeniser时缺少空字段

我希望将结果存储在db中，如下所示， 小鬼 2223 9481851276 7654321 无效的 无效的 三十三

问题是什么？什么不起作用？我想要像这个IMPS 343444 9481851276 7654321 null 956756345这样的存储字符串。但它会忽略空值，例如IMPS 343444 9481851276 7654321 956756345
