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("\u2615- 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);

SubscriptSpan
public SubscriptSpan (Parcel src)
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 | |
toString
public String toString ()
Returns a string representation of the object.
| Returns | |
|---|---|
String | a string representation of the object. |

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. 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 |
