本文实例讲述了android编程实现添加文本内容到sqlite表中的方法。分享给大家供大家参考,具体如下:
第一步: 创建表

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:

// 添加问题到数据库

// 添加答案2到数据库
String answerStr2 = localBufferReader.readLine();
if (answerStr2 == null ) {
localBufferReader. close ();
db. close ();
break;
}
Log.v( "insert" , "insert answerContent2 " + answerStr2
+ " success!" );
ContentValues answerContent2 = new ContentValues();
answerContent2.put( "answerId" , i);
answerContent2.put( "content" , answerStr2);
db. insert ( "DLION" , "_id" , answerContent2);
// 添加答案3到数据库
String answerStr3 = localBufferReader.readLine();
if (answerStr3 == null ) {
localBufferReader. close ();
db. close ();
break;
}
Log.v( "insert" , "insert answerContent3 " + answerStr3
+ " success!" );
ContentValues answerContent3 = new ContentValues();

answerContent3.put( "content" , answerStr3);
db. insert ( "DLION" , "_id" , answerContent3);
// 添加答案4到数据库
String answerStr4 = localBufferReader.readLine();
if (answerStr4 == null ) {
localBufferReader. close ();
db. close ();
break;
}
Log.v( "insert" , "insert answerContent4 " + answerStr4
+ " success!" );
ContentValues answerContent4 = new ContentValues();
answerContent4.put( "answerId" , i);
answerContent4.put( "content" , answerStr4);
db. insert ( "DLION" , "_id" , answerContent4);
}
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
}
