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.

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 |

Returns | |

Returns the array of input filters that are currently applied to changes to this Editable.
Returns | |
---|---|
InputFilter[] |
insert

Convenience for replace(where, where, text, 0, text.length());
Parameters | |

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.
