CREATE TABLE DLION ( _id INTEGER PRIMARY KEY AUTOINCREMENT, content TEXT, questionId INTEGER, answerId INTEGER, [right] INTEGER); |
第二步： 把编辑文本内容并放到 res/raw/test.txt
用 Notepad++ 打开，把每一个将要放在表中单元格的内容放一行
去除行尾空格和空白行：按CTRL+H 选择正则表达式-- 查找目标：\s+$ 替换为空
去除行首空格：按CTRL+H 选择正则表达式-- 查找目标：^\s+ 替换为空
第三步： 打开数据库 详情参照：
第四步： 添加数据到表
