| android.text.Editable | 
This is the interface for text whose content and markup
 can be changed (as opposed
 to immutable text like Strings).  If you make a DynamicLayout
 of an Editable, the layout will be reflowed as the text is changed.

Public methods
append
public abstract Editable append (char text)
Convenience for append(String.valueOf(text)).
| Parameters | |
|---|---|
| text | char: The character to append | 
| Returns | |
|---|---|
| Editable | A reference to this Appendable | 
append
public abstract Editable append (CharSequence text, int start, int end)
Convenience for replace(length(), length(), text, start, end)
| Parameters | |
|---|---|
| text | CharSequence: The character sequence from which a subsequence will be
         appended.  Ifcsqisnull, then characters
         will be appended as ifcsqcontained the four
         characters"null". | 
| start | int: The index of the first character in the subsequence | 
| end | int: The index of the character following the last character in the
         subsequence | 
| Returns | |
|---|---|
| Editable | A reference to this Appendable | 
append
public abstract Editable append (CharSequence text)
Convenience for replace(length(), length(), text, 0, text.length())
| Parameters | |
|---|---|
| text | CharSequence: The character sequence to append.  Ifcsqisnull, then the four characters"null"are
         appended to this Appendable. | 
| Returns | |
|---|---|
| Editable | A reference to this Appendable | 
clear
public abstract void clear ()
Convenience for replace(0, length(), "", 0, 0).
 Note that this clears the text, not the spans;
 use clearSpans() if you need that.
clearSpans
public abstract void clearSpans ()
Removes all spans from the Editable, as if by calling
 Spannable.removeSpan(Object) on each of them.
delete
public abstract Editable delete (int st, int en)
Convenience for replace(st, en, "", 0, 0)
| Parameters | |
|---|---|
| st | int | 
| en | int | 
| Returns | |
|---|---|
| Editable | |
getFilters
public abstract InputFilter[] getFilters ()
Returns the array of input filters that are currently applied to changes to this Editable.
| Returns | |
|---|---|
| InputFilter[] | |
insert
public abstract Editable insert (int where, CharSequence text)
Convenience for replace(where, where, text, 0, text.length());
| Parameters | |
|---|---|
| where | int | 
| text | CharSequence | 
| Returns | |
|---|---|
| Editable | |
insert
public abstract Editable insert (int where, CharSequence text, int start, int end)
Convenience for replace(where, where, text, start, end)
| Parameters | |
|---|---|
| where | int | 
| text | CharSequence | 
| start | int | 
| end | int | 
| Returns | |
|---|---|
| Editable | |
replace
public abstract Editable replace (int st, int en, CharSequence source, int start, int end)
Replaces the specified range (st…en) of text in this
 Editable with a copy of the slice start…end from
 source.  The destination slice may be empty, in which case
 the operation is an insertion, or the source slice may be empty,
 in which case the operation is a deletion.
 
 Before the change is committed, each filter that was set with
 setFilters(InputFilter) is given the opportunity to modify the
 source text.
 
 If source
 is Spanned, the spans from it are preserved into the Editable.
 Existing spans within the Editable that entirely cover the replaced
 range are retained, but any that were strictly within the range
 that was replaced are removed. If the source contains a span
 with Spanned.SPAN_PARAGRAPH flag, and it does not satisfy the
 paragraph boundary constraint, it is not retained. As a special case, the
 cursor position is preserved even when the entire range where it is located
 is replaced.
| Parameters | |
|---|---|
| st | int | 
| en | int | 
| source | CharSequence | 
| start | int | 
| end | int | 
| Returns | |
|---|---|
| Editable | a reference to this object. |
