        | Editable | This is the interface for text whose content and markup
 can be changed (as opposed
 to immutable text like Strings). |  
        | PrecomputedText | A text which has the character metrics data. |  
        | SpannableString | This is the class for text whose content is immutable but to which
 markup objects can be attached and detached. |  
        | SpannableStringBuilder | This is the class for text whose content and markup can both be changed. |  | 
  
    
  This is the interface for text to which markup objects can be
 attached and detached.  Not all Spannable classes have mutable text;
 see Editable for that.

        | int | SPAN_COMPOSINGThis flag is set on spans that are being used to apply temporary
 styling information on the composing text of an input method, so that
 they can be found and removed when the composing text is being
 replaced.
          
    
 |  
        | int | SPAN_EXCLUSIVE_EXCLUSIVESpans of type SPAN_EXCLUSIVE_EXCLUSIVE do not expand
 to include text inserted at either their starting or ending point.
          
    
 |  
        | int | SPAN_EXCLUSIVE_INCLUSIVENon-0-length spans of type SPAN_EXCLUSIVE_INCLUSIVE expand
 to include text inserted at their ending point but not at their
 starting point.
          
    
 |  
        | int | SPAN_INCLUSIVE_EXCLUSIVENon-0-length spans of type SPAN_INCLUSIVE_EXCLUSIVE expand
 to include text inserted at their starting point but not at their
 ending point.
          
    
 |  
        | int | SPAN_INCLUSIVE_INCLUSIVESpans of type SPAN_INCLUSIVE_INCLUSIVE expand
 to include text inserted at either their starting or ending point.
          
    
 |  
        | int | SPAN_INTERMEDIATEThis flag will be set for intermediate span changes, meaning there
 is guaranteed to be another change following it.
          
    
 |  
        | int | SPAN_MARK_MARK0-length spans with type SPAN_MARK_MARK behave like text marks:
 they remain at their original offset when text is inserted
 at that offset.
          
    
 |  
        | int | SPAN_MARK_POINTSPAN_MARK_POINT is a synonym for SPAN_INCLUSIVE_INCLUSIVE. |  
        | int | SPAN_PARAGRAPHSPAN_PARAGRAPH behaves like SPAN_INCLUSIVE_EXCLUSIVE
 (SPAN_MARK_MARK), except that if either end of the span is
 at the end of the buffer, that end behaves like _POINT
 instead (so SPAN_INCLUSIVE_INCLUSIVE if it starts in the
 middle and ends at the end, or SPAN_EXCLUSIVE_INCLUSIVE
 if it both starts and ends at the end).
          
    
 |  
        | int | SPAN_POINT_MARKSPAN_POINT_MARK is a synonym for SPAN_EXCLUSIVE_EXCLUSIVE. |  
        | int | SPAN_POINT_MARK_MASKBitmask of bits that are relevent for controlling point/mark behavior
 of spans.
          
    
 |  
        | int | SPAN_POINT_POINT0-length spans with type SPAN_POINT_POINT behave like cursors:
 they are pushed forward by the length of the insertion when text
 is inserted at their offset.
          
    
 |  
        | int | SPAN_PRIORITYThe bits specified by the SPAN_PRIORITY bitmap determine the order
 of change notifications -- higher numbers go first.
          
    
 |  
        | int | SPAN_PRIORITY_SHIFTThe bits numbered just above SPAN_PRIORITY_SHIFT determine the order
 of change notifications -- higher numbers go first.
          
    
 |  
        | int | SPAN_USERThe bits specified by the SPAN_USER bitfield are available
 for callers to use to store scalar data associated with their
 span object.
          
    
 |  
        | int | SPAN_USER_SHIFTThe bits numbered SPAN_USER_SHIFT and above are available
 for callers to use to store scalar data associated with their
 span object.

Public methods
    removeSpan
    
public abstract void removeSpan (Object what)
    
    
    
  Remove the specified object from the range of text to which it
 was attached, if any.  It is OK to remove an object that was never
 attached in the first place.
    
 
    setSpan
    
public abstract void setSpan (Object what, 
                int start, 
                int end, 
                int flags)
    
    
    
  Attach the specified markup object to the range start…end
 of the text, or move the object to that range if it was already
 attached elsewhere.  See Spanned for an explanation of
 what the flags mean.  The object can be one that has meaning only
 within your application, or it can be one that the text system will
 use to affect text display or behavior.  Some noteworthy ones are
 the subclasses of CharacterStyle and
 ParagraphStyle, and
 TextWatcher and
 SpanWatcher.
