Implement html tags in SQLite database

问题

I have entered some text wrapped with html tags in SQLite database, and I want to display those text in phone. for example: I have entered 10<sup>-7</sup> in SQLite database, I want to render 10^-7 in phone.

This is the image of SQLite from DB Browser for SQLite:

This is part of the DBHelper:

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;
    }

Okay! I got your point, you want to add super and sub scripts in your quiz app. Rather than using latex, you should add superscript and subscript letters in your sqlite db file, you can find many generators online https://lingojam.com/SuperscriptGenerator this is my personal favorite! generate and copy paste the letter in your sqlite db.
