ParcelableSpan
java.lang.Object | |||
↳ | android.text.style.CharacterStyle | ||
↳ | android.text.style.MetricAffectingSpan | ||
↳ | android.text.style.ScaleXSpan |
Scales horizontally the size of the text to which it's attached by a certain factor.
Values > 1.0 will stretch the text wider. Values < 1.0 will stretch the text narrower.
For example, a ScaleXSpan
that stretches the text size by 100% can be
constructed like this:
SpannableString string = new SpannableString("Text with ScaleX span");
string.setSpan(new ScaleXSpan(2f), 10, 16, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

ScaleXSpan
public ScaleXSpan (float proportion)
Creates a ScaleXSpan
based on a proportion. Values > 1.0 will stretch the text wider.
Values < 1.0 will stretch the text narrower.
Parameters | |
---|---|
proportion |
float : the horizontal scale factor.
Value is 0 or greater |
ScaleXSpan
public ScaleXSpan (Parcel src)
Creates a ScaleXSpan
from a parcel.
Parameters | |
---|---|
src |
Parcel : This value cannot be null . |
Public methods
describeContents
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(android.os.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.
Value is either 0 or CONTENTS_FILE_DESCRIPTOR |
getScaleX
public float getScaleX ()
Get the horizontal scale factor for the text.
Returns | |
---|---|
float |
the horizontal scale factor. |
getSpanTypeId
public int getSpanTypeId ()
Return a special type identifier for this span class.
Returns | |
---|---|
int |
toString
public String toString ()
Returns a string representation of the object.
Returns | |
---|---|
String |
a string representation of the object. |
updateDrawState
public void updateDrawState (TextPaint ds)
Parameters | |
---|---|
ds |
TextPaint |
updateMeasureState
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 cannot be null . |
writeToParcel
public void writeToParcel (Parcel dest, int flags)
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.PARCELABLE_WRITE_RETURN_VALUE .
Value is either 0 or a combination of Parcelable.PARCELABLE_WRITE_RETURN_VALUE , and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
