android.text.Spanned

int

This 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

Spans of type SPAN\_EXCLUSIVE\_EXCLUSIVE do not expand

to include text inserted at either their starting or ending point.

int

Non-0-length spans of type SPAN\_EXCLUSIVE\_INCLUSIVE expand

to include text inserted at their ending point but not at their

starting point.

int

Non-0-length spans of type SPAN\_INCLUSIVE\_EXCLUSIVE expand

to include text inserted at their starting point but not at their

ending point.

int

Spans of type SPAN\_INCLUSIVE\_INCLUSIVE expand

to include text inserted at either their starting or ending point.

int

This flag will be set for intermediate span changes, meaning there

is guaranteed to be another change following it.

int

0-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\_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

Bitmask of bits that are relevent for controlling point/mark behavior

of spans.

int

0-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

The bits specified by the SPAN\_PRIORITY bitmap determine the order

of change notifications -- higher numbers go first.

int

The bits numbered just above SPAN\_PRIORITY\_SHIFT determine the order

of change notifications -- higher numbers go first.

int

The bits specified by the SPAN\_USER bitfield are available

for callers to use to store scalar data associated with their

span object.

int

The bits numbered SPAN\_USER\_SHIFT and above are available

for callers to use to store scalar data associated with their

span object.

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

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. As a special case, the cursor

position is preserved even when the entire range where it is

located is replaced.

Returns

a reference to this object.
