RelativeSizeSpan

---

Kotlin |Java

open class RelativeSizeSpan : MetricAffectingSpan, ParcelableSpan

kotlin.Any
↳	android.text.style.CharacterStyle
	↳	android.text.style.MetricAffectingSpan
		↳	android.text.style.RelativeSizeSpan

Uniformly scales the size of the text to which it's attached by a certain proportion.

For example, a RelativeSizeSpan that increases the text size by 50% can be constructed like this:

<code>SpannableString string = new SpannableString("Text with relative size span");
 string.setSpan(new RelativeSizeSpan(1.5f), 10, 24, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);</code>

Text increased by 50% with RelativeSizeSpan.

Summary

Public constructors
RelativeSizeSpan(src: Parcel) Creates a RelativeSizeSpan from a parcel.
RelativeSizeSpan(proportion: Float) Creates a RelativeSizeSpan based on a proportion.

Public methods
open Int	describeContents()
open Float	getSizeChange()
open Int	getSpanTypeId()
open String	toString()
open Unit	updateDrawState(ds: TextPaint)
open Unit	updateMeasureState(ds: TextPaint) Classes that extend MetricAffectingSpan implement this method to update the text formatting in a way that can change the width or height of characters.
open Unit	writeToParcel(dest: Parcel, flags: Int) Flatten this object in to a Parcel.

Inherited functions
From class MetricAffectingSpan MetricAffectingSpan! getUnderlying() Returns "this" for most MetricAffectingSpans, but for MetricAffectingSpans that were generated by wrap, returns the underlying MetricAffectingSpan.
From class CharacterStyle Unit updateDrawState(tp: TextPaint!) CharacterStyle! wrap(cs: CharacterStyle!) A given CharacterStyle can only applied to a single region of a given Spanned. If you need to attach the same CharacterStyle to multiple regions, you can use this method to wrap it with a new object that will have the same effect but be a distinct object so that it can also be attached without conflict.
