AbsoluteSizeSpan

public class AbsoluteSizeSpan
extends MetricAffectingSpan implements ParcelableSpan

java.lang.Object
   ↳ android.text.style.CharacterStyle
     ↳ android.text.style.MetricAffectingSpan
       ↳ android.text.style.AbsoluteSizeSpan


A span that changes the size of the text it's attached to.

For example, the size of the text can be changed to 55dp like this:

SpannableString string = new SpannableString("Text with absolute size span");
string.setSpan(new AbsoluteSizeSpan(55, true), 10, 23, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
Text with text size updated.

Summary

Inherited constants

Public constructors

AbsoluteSizeSpan(int size)

Set the text size to size physical pixels.

AbsoluteSizeSpan(int size, boolean dip)

Set the text size to size physical pixels, or to size device-independent pixels if dip is true.

AbsoluteSizeSpan(Parcel src)

Creates an AbsoluteSizeSpan from a parcel.

Public methods

int describeContents()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.

boolean getDip()

Returns whether the size is in device-independent pixels or not, depending on the dip flag passed in AbsoluteSizeSpan(int, boolean)

int getSize()

Get the text size.

int getSpanTypeId()

Return a special type identifier for this span class.

void updateDrawState(TextPaint ds)
void updateMeasureState(TextPaint ds)

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

void writeToParcel(Parcel dest, int flags)

Flatten this object in to a Parcel.

Public constructors

AbsoluteSizeSpan

added in API level 1
public AbsoluteSizeSpan (int size)

Set the text size to size physical pixels.

Parameters
size int

AbsoluteSizeSpan

added in API level 5
public AbsoluteSizeSpan (int size, 
                boolean dip)

Set the text size to size physical pixels, or to size device-independent pixels if dip is true.

Parameters
size int

dip boolean

AbsoluteSizeSpan

added in API level 3
public AbsoluteSizeSpan (Parcel src)

Creates an AbsoluteSizeSpan from a parcel.

Parameters
src Parcel

This value must never be null.

Public methods

describeContents

added in API level 3
public int describeContents ()

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(Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
int a bitmask indicating the set of special object types marshaled by this Parcelable object instance.

getDip

added in API level 5
public boolean getDip ()

Returns whether the size is in device-independent pixels or not, depending on the dip flag passed in AbsoluteSizeSpan(int, boolean)

Returns
boolean true if the size is in device-independent pixels, false otherwise

getSize

added in API level 1
public int getSize ()

Get the text size. This is in physical pixels if getDip() returns false or in device-independent pixels if getDip() returns true.

Returns
int the text size, either in physical pixels or device-independent pixels.

getSpanTypeId

added in API level 3
public int getSpanTypeId ()

Return a special type identifier for this span class.

Returns
int

updateDrawState

added in API level 1
public void updateDrawState (TextPaint ds)

Parameters
ds TextPaint

This value must never be null.

updateMeasureState

added in API level 1
public void updateMeasureState (TextPaint ds)

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
ds TextPaint: the paint used for drawing the text

This value must never be null.

writeToParcel

added in API level 3
public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
dest Parcel: The Parcel in which the object should be written.

This value must never be null.

flags int: Additional flags about how the object should be written. May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE.
