I like this csv reader: https://mvnrepository.com/artifact/net.sf.opencsv/opencsv/2.3

Just add it to your project.

Example code (assuming there is the file assets/test.csv):

        String next[] = {};
        List<String[]> list = new ArrayList<String[]>();

        try {
            CSVReader reader = new CSVReader(new InputStreamReader(getAssets().open("test.csv")));
            while(true) {
                next = reader.readNext();
                if(next != null) {
                    list.add(next);
                } else {
                    break;
                }
            }
        } catch (IOException e) {
            e.printStackTrace();
        }

You can access the imported data with, for example,

list.get(1)[1]

That would return a string.
