android - Android 中保存到数据库时去掉括号

Question

我正在我的数据库中保存一个数组列表。但是当我保存它时会发生什么，是这样的:

我想从最后一列的数据中删除括号，我希望我的数据库像这样:

这是我的代码:

ArrayList<String> content = new ArrayList<String>();
    for (int j=0; j<checkSelected.length; j++) {
        if(checkSelected[j]==true) {
            String values = BrandListAdapter.mListItems.get(j);
            Cursor rSubBrand = databaseHandler.getReport_SubBrandCode(values);
            String SubBrandCode = rSubBrand.getString(rSubBrand.getColumnIndex(Constants.SUBBRAND_CODE));
            content.clear();
            content.add(SubBrandCode);

            String subBrand = content.toString();

            databaseHandler.SaveSubBrand(new Cons_iReport (ReportCode, subBrand));
    }                       
}

我只是想明白了。我无法删除括号的原因是因为我没有将其分配给将保存到数据库的'subBrand'。

ArrayList<String> content = new ArrayList<String>();
    for (int j=0; j<checkSelected.length; j++) {
        if(checkSelected[j]==true) {
            String values = BrandListAdapter.mListItems.get(j);
            Cursor rSubBrand = databaseHandler.getReport_SubBrandCode(values);
            String SubBrandCode = rSubBrand.getString(rSubBrand.getColumnIndex(Constants.SUBBRAND_CODE));
            content.clear();
            content.add(SubBrandCode);

            String subBrand = content.toString();
            subBrand = subBrand.replace("[", ""); // this is what I mean...
            subBrand = subBrand.replace("]", "");

            databaseHandler.SaveSubBrand(new Cons_iReport (ReportCode, subBrand));
        }                       
    }
