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

The HTML.fromHTML(String) was deprecated as of API 24. They say to use this one instead, which supports flags as a parameter. So to go off of the accepted answer:

TextView textView = ((TextView)findViewById(R.id.text));
textView.setText(Html.fromHtml("X2", Html.FROM_HTML_MODE_LEGACY));

And if you want code that considers pre-24 API's as well:

TextView textView = ((TextView)findViewById(R.id.text));
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N) {
  textView.setText(Html.fromHtml("X2", Html.FROM_HTML_MODE_LEGACY));
} else {
    textView.setText(Html.fromHtml("X2"));    
}
