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

If you want to set the superscript from string.xml file try this:

string resource:

<string name="test_string">X&lt;sup&gt;3&lt;/sup&gt;</string>

if you want the superscript to be smaller:

<string name="test_string">X&lt;sup&gt;&lt;small&gt;3&lt;/small&gt;&lt;/sup&gt;</string>

Code:

textView.setText(Html.fromHtml("Anything you want to put here"+getString(R.string.test_string)));

Answer 2

I found this article on how to use a Spannable or in a string resource file: <sup> or <sub> for superscript and subscript, respectively.

Answer 3

yourTextView.setText(Html.fromHtml("X<sup>2</sup>"));

This will be the result in you yourTextView =

X²

Answer 4

It bit late but following just work fine, use superscript as special character, I used spacial char here.

<string name="str">H₂</string>

Answer 5

In the code just put this "\u00B2" Like this:

textView.setText("X\u00B2");

Answer 6

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

(or) From String Resource File:

<string name="test_string">
  <![CDATA[ X<sup><small>2</small></sup> ]]>
</string>
