kitkat中的文本呈现问题

Question

我正在开发Android阿拉伯语应用。我从sqlite DB获得了阿拉伯字符串。我的应用程序在android 4.2版本中显示正确的阿拉伯文字样式但是当我在android 4.4 kitkat中运行这个应用程序时，文本样式不合适。为什么Android 4.4中的文字样式会发生变化？

            urduTV.setLayoutParams(ulp);
            urduTV.setText(urdu);
            urduTV.setTypeface(urduFont);
            urduTV.setPadding(1, 2, 1, 2);
            urduTV.setTextColor(Color.BLACK);
            urduTV.setTextSize(35);
            tableRow.addView(urduTV);

            TableRow.LayoutParams alp = new TableRow.LayoutParams(230, TableRow.LayoutParams.WRAP_CONTENT);
            alp.setMargins(0, 3, 0, 4);
            arabicTV = new TextView(this);
            arabicTV.setLayoutParams(alp);
            arabicTV.setText(ayyat);
            arabicTV.setTypeface(arabicFont);
            arabicTV.setPadding(1, 2, 1, 2);
            arabicTV.setTextColor(Color.BLACK);
            arabicTV.setTextSize(35);
            tableRow.addView(arabicTV);


            tablelayout.addView(tableRow);
