SubscriptSpan

public class SubscriptSpan
extends MetricAffectingSpan implements ParcelableSpan

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


The span that moves the position of the text baseline lower.

The span can be used like this:

SpannableString string = new SpannableString("☕- C8H10N4O2\n");
string.setSpan(new SubscriptSpan(), 4, 5, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
string.setSpan(new SubscriptSpan(), 6, 8, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
string.setSpan(new SubscriptSpan(), 9, 10, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
string.setSpan(new SubscriptSpan(), 11, 12, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
Text with SubscriptSpan.
Note: Since the span affects the position of the text, if the text is on the last line of a TextView, it may appear cut.

Creates a SubscriptSpan 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

getSpanTypeId

public int getSpanTypeId ()

Return a special type identifier for this span class.

Returns
int

public void updateDrawState (TextPaint textPaint)

Parameters
textPaint TextPaint: This value cannot be null.

updateMeasureState

public void updateMeasureState (TextPaint 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.

Parameters
textPaint TextPaint: This value cannot be null.

writeToParcel

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.

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
