Question

我有一个数组。并且数组的每个单元格都有一些文本，并且可以包含换行符（\ n）。我需要从这个数组插入数据到sqlite数据库。我已经做了。但是当我使用来自db的数据时我会丢失换行符号，并且我在一行上获得数据。如何解决这个问题。将数据插入数据库：

public void insert(String key, String value) {
    String sql = "INSERT INTO words(key, value) VALUES(?,?)";
    Connection conn = this.connect();
    try {
        PreparedStatement pstmt = conn.prepareStatement(sql);
        pstmt.setString(1,key);
        pstmt.setString(2,value);
        pstmt.executeUpdate();
    } catch (SQLException e) {
        System.out.println(e.getMessage());
    }
}

public static void main(String[] args) throws IOException, InterruptedException{
Main app = new Main();
while(values.size() > 0) {
            System.out.println("db: " + ++c);
            app.insert(words.poll(), values.poll());
        }
    }

在我的Android应用程序上从db获取数据：

final Word word = mDBHelper.getWord(value, mDicType);
tvWordTranslate = (WebView)view.findViewById(R.id.tvWordTranslate);
String text = "<html><head>"
        + "<style type=\"text/css\">body{color: #27009b; background-color: #FFFFFF;}"
        + "</style></head>"
        + "<body>"
        + word.value+ "</body></html>";
        tvWordTranslate.loadDataWithBaseURL(null, text, "text/html", "utf-8", null);

// word.value可以包含换行符从db获取单词的函数：

public Word getWord(String key, int dicType) {
        String tableName = getTableName(dicType);
        String q = "SELECT * FROM  " + tableName + " WHERE upper([key]) = upper(?)";
        Cursor result = mDB.rawQuery(q, new String[]{key});
        Word word = new Word();
        while(result.moveToNext()) {
            word.key = result.getString(result.getColumnIndex(COL_KEY));
            word.value = result.getString(result.getColumnIndex(COL_VALUE));
        }
        return word;
    }

在sqlite数据库中插入换行符
