You can try this solution: http://blog.sqisland.com/2014/11/android-stacked-fractions.html

Basically, you have to looking for a font that supports afrc. Now, you can play with your TextViews and TagHandlers until you get the result desired.

The solution does not seem simple, however if you want to try fraction in xml, go to this website.

http://unicode-search.net/unicode-namesearch.pl?term=fraction

This code worked for me to show 1⁄4.

The xml code is.

<TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="5dp"
            android:layout_marginRight="5dp"
            android:textAppearance="?android:attr/textAppearanceSmall"
            android:text="\u00BC"
            android:id="@+id/textView"
            android:textSize="25sp" />

The required line is android:text="\u00BC" to show 1⁄4 as fraction.

So if you want to show 1⁄2 or any other as fraction from the above mentioned website, just append the last two characters(in this case BD) to \u00.

So 1/2 becomes \u00BD

Use html format. However you must add a extra space on the top and bottom to keep it from being cut off.

 SpannableStringBuilder test = new SpannableStringBuilder();
 test.append("\n");
 test.append(Html.fromHtml("<sup>5</sup>/<sub>9</sub>"));
 test.append("\n");
