android 添加文本内容到sqlite表中

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(注： ^ 代表行首 $ 代表行尾)

　　　　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

　　android sd卡读取数据库

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();

        }

    }
