How to Create Subscript and Superscript Text in Android Without External Libraries?

Subscript and Superscript Strings in Android

Enhancing text presentation in Android often involves adding stylistic elements such as subscripts and superscripts. This guide explores how to effectively display strings with these attributes within Android applications, without resorting to external libraries.

Method:

To add subscripts or superscripts to strings in Android, utilize the Android.text.Html class. This class provides methods to escape HTML tags and support inline styling within strings.

Example:

To display a string with a subscript, use the ^tag:

((TextView)findViewById(R.id.text)).setText(Html.fromHtml("X<sup>2</sup>"));

Alternatively, you can utilize the ^and tags to encapsulate the superscript portion of your string:

((TextView)findViewById(R.id.text)).setText(Html.fromHtml("X<sup>2</sup>"));

Additional Notes:

• The Html.fromHtml() method expects the input string to be HTML formatted.
• It's important to escape special characters in your string, such as "<" and "&", to ensure proper rendering.
• This method works well with any TextView component within your Android application.
