Subscript and Superscript a String in Android

Question

How can you print a string with a subscript or superscript? Can you do this without an external library? I want this to display in a TextView in Android.

Answer 1

In the strings.xml files, you can just use the HTML <sup>3</sup> tag. Work perfectly for me

EXAMPLE

<string name="turnoverRate">Turnover rate m<sup>3</sup>/m<sup>2</sup>/hour:</string>

Answer 2

They are called Unicode characters, and Android TextView supports them. Copy the super/sub-script you want from this Wiki: https://en.wikipedia.org/wiki/List_of_Unicode_characters#Superscripts_and_Subscripts

Answer 3

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

This will be the result in you yourTextView =

X²

Answer 5

Android String Resource Superscript and Subscript for letters

You don't really have to use html document if any of the letters you want is represented here

For "a" copy and paste this "ᵃ"

You can copy and paste any of these Superscripts and Subscripts directly into your Android String Resource.

Example:

    <string name="word_with_superscript" translatable="false">Trademark ᵀᴹ</string>

Result:Trademark ᵀᴹ

Answer 6

Based on Gerardo's answer here I created this extension on Int

fun Int.toSuperScript(): String {
    return when (this) {
        0 -> "\u2070"
        1 -> "\u00B9"
        2 -> "\u00B2"
        3 -> "\u00B3"
        4 -> "\u2074"
        5 -> "\u2075"
        6 -> "\u2076"
        7 -> "\u2077"
        8 -> "\u2078"
        9 -> "\u2079"
        else -> ""
}

}
