在 SQLite 数据库中实现 html 标签

Question

我在 SQLite 数据库中输入了一些用 html 标签包裹的文本，我想在手机中显示这些文本。例如：我在 SQLite 数据库中输入了10<sup>-7</sup>，我想在手机中渲染 10^-7。

这是来自 DB Browser for SQLite 的 SQLite 图像：

这是 DBHelper 的一部分：

public List<Quizplay> getQuestionGuj(int cate_id, int sub_cate_id, int noOfQuestion, int level) {

        List<Quizplay> quizplay = new ArrayList<Quizplay>();
        int total = noOfQuestion;
        String sql = "select *  FROM " + TBL_QUESTION + " where (" + CATE_ID + "=" + cate_id + " and "
                + SUB_CATE_ID + " =" + sub_cate_id + " and "
                + LEVEL + "=" + level + ") ORDER BY RANDOM() LIMIT " + total;
        SQLiteDatabase db = this.getReadableDatabase();
        //SQLiteDatabase db = SQLiteDatabase.openDatabase("/data/data/" + packageName + "/databases/" + DATABASE_NAME, null, 0);
        Cursor cursor = db.rawQuery(sql, null);

        if (cursor.moveToFirst()) {
            do {
                Quizplay question = new Quizplay();
                question.setId(cursor.getInt(cursor.getColumnIndex("id")));
                question.setQuestion(cursor.getString(cursor.getColumnIndex("question")));
                question.addOption(cursor.getString(cursor.getColumnIndex("option_a")));
                question.addOption(cursor.getString(cursor.getColumnIndex("option_b")));
                question.addOption(cursor.getString(cursor.getColumnIndex("option_c")));
                question.addOption(cursor.getString(cursor.getColumnIndex("option_d")));
                String rightAns = cursor.getString(cursor.getColumnIndex("right_answer"));
                if (rightAns.equalsIgnoreCase("A")) {
                    question.setTrueAns(cursor.getString(cursor.getColumnIndex("option_a")));
                } else if (rightAns.equalsIgnoreCase("B")) {
                    question.setTrueAns(cursor.getString(cursor.getColumnIndex("option_b")));
                } else if (rightAns.equalsIgnoreCase("C")) {
                    question.setTrueAns(cursor.getString(cursor.getColumnIndex("option_c")));
                } else {
                    question.setTrueAns(cursor.getString(cursor.getColumnIndex("option_d")));
                }
                if (question.getOptions().size() == 4) {
                    quizplay.add(question);
                }

            } while (cursor.moveToNext());
        }
        cursor.close();
        db.close();
        Collections.shuffle(quizplay);
        quizplay = quizplay.subList(0, noOfQuestion);
        return quizplay;
    }

好的！我明白你的意思，你想在你的测验应用程序中添加超级脚本和子脚本。 而不是使用乳胶，你应该在你的 sqlite db 文件中添加上标和下标字母， 你可以在网上找到很多发电机 https://lingojam.com/SuperscriptGenerator 这是我个人的最爱！ 生成并复制将字母粘贴到您的 sqlite 数据库中。
