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()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
open Float	`getSizeChange()`
open Int	`getSpanTypeId()` Return a special type identifier for this span class.
open String	`toString()` Returns a string representation of the object.
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.

Public constructors

RelativeSizeSpan

Added in API level 3

RelativeSizeSpan(src: Parcel)

Creates a RelativeSizeSpan from a parcel.

Parameters
`src`	Parcel: This value cannot be `null`.

RelativeSizeSpan

Added in API level 1

RelativeSizeSpan(proportion: Float)

Creates a RelativeSizeSpan based on a proportion.

Parameters
`proportion`	Float: the proportion with which the text is scaled. Value is 0.0f or greater

Public methods

describeContents

Added in API level 3

open fun describeContents(): Int

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel,int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Return
`Int`	a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or `CONTENTS_FILE_DESCRIPTOR`

getSizeChange

Added in API level 1

open fun getSizeChange(): Float

Return
`Float`	the proportion with which the text size is changed.

getSpanTypeId

Added in API level 3

open fun getSpanTypeId(): Int

Return a special type identifier for this span class.

toString

Added in API level 1

open fun toString(): String

Returns a string representation of the object.

Return
`String`	a string representation of the object.

updateDrawState

Added in API level 1

open fun updateDrawState(ds: TextPaint): Unit

Parameters
`ds`	TextPaint: This value cannot be `null`.

updateMeasureState

Added in API level 1

open fun updateMeasureState(ds: TextPaint): Unit

Classes that extend MetricAffectingSpan implement this method to update the text formatting in a way that can change the width or height of characters.

Parameters
`textPaint`	the paint used for drawing the text. This value cannot be `null`.
`ds`	TextPaint: This value cannot be `null`.

writeToParcel

Added in API level 3

open fun writeToParcel(
    dest: Parcel, 
    flags: Int
): Unit

Flatten this object in to a Parcel.

Parameters
`dest`	Parcel: This value cannot be `null`.
`flags`	Int: Additional flags about how the object should be written. May be 0 or `PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of the following: `PARCELABLE_WRITE_RETURN_VALUE`
