↳ | 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:
SpannableString string = new SpannableString("Text with relative size span");
string.setSpan(new RelativeSizeSpan(1.5f), 10, 24, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

Public methods
describeContents
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. |
getSizeChange
float getSizeChange ()
Returns | |
---|---|
float |
the proportion with which the text size is changed. |
getSpanTypeId
int getSpanTypeId ()
Return a special type identifier for this span class.
Returns | |

Parameters | |
---|---|
ds |
TextPaint This value must never be |
updateMeasureState
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 |
writeToParcel
void writeToParcel (Parcel dest, int flags)
Flatten this object in to a Parcel.
Parameters | |
