如何在Android上标记CSV行并将空白列包括为空字符串？

Question

I want to read a CSV file in Android, but for rows with some blank columns, CSV writes something like this:

,,,,ABC,,,d,mfcmf,fgt,

When I tokenize the above line I get ABC as the first string, when I need "" (ie an empty string).

How can I tokenize CSV rows, but have blank columns show up in the results as empty strings?

First_column  = "";
Second_column = "";
Third_column  = "";
Forth_column  = "";
Fifth_column  = "ABC";

You could write your own little parser or use a CSV library. To simply split the string on comma characters does not work if there are embedded commas in a field like here

a,1,"some , in string",12

One library that could be used in Apache Commons CSV
