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：
第四步： 添加数据到表
public void addContent() {
try {
BufferedReader localBufferReader = new BufferedReader(
new InputStreamReader(getResources().openRawResource(
R.raw.test)));
db = openDatabase();
for (int i = length + 1;; i++) {
// 添加问题到数据库
String questionStr = localBufferReader.readLine();
if (questionStr == null) {
localBufferReader.close();
db.close();
break;
}
Log.v("insert", "insert questionContent " + questionStr
+ " success!");
db.execSQL("insert into DLION(questionId,content) values(" + i
+ ",'" + questionStr + "')");
// 添加答案1到数据库
String answerStr1 = localBufferReader.readLine();
if (answerStr1 == null) {
localBufferReader.close();
db.close();
break;
}
Log.v("insert", "insert answerContent1 " + answerStr1
+ " success!");
db.execSQL("insert into DLION(answerId,content) values(" + i
+ ",'" + answerStr1 + "')");
// 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("answerId", i);
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();
}
}
