Public constructors
Standard
public Standard (int first, int rest)
Constructor taking separate indents for the first and subsequent lines.
Parameters | |
---|---|
first |
int : the indent for the first line of the paragraph |
rest |
int : the indent for the remaining lines of the paragraph |
Standard
public Standard (int every)
Constructor taking an indent for all lines.
Parameters | |
---|---|
every |
int : the indent of each line |
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 |
drawLeadingMargin
public void drawLeadingMargin (Canvas c, Paint p, int x, int dir, int top, int baseline, int bottom, CharSequence text, int start, int end, boolean first, Layout layout)
Renders the leading margin. This is called before the margin has been
adjusted by the value returned by getLeadingMargin(boolean)
.
Parameters | |
---|---|
c |
Canvas : the canvas |
p |
Paint : the paint. The this should be left unchanged on exit. |
x |
int : the current position of the margin |
dir |
int : the base direction of the paragraph; if negative, the margin
is to the right of the text, otherwise it is to the left. |
top |
int : the top of the line |
baseline |
int : the baseline of the line |
bottom |
int : the bottom of the line |
text |
CharSequence : the text |
start |
int : the start of the line |
end |
int : the end of the line |
first |
boolean : true if this is the first line of its paragraph |
layout |
Layout : the layout containing this line |
getLeadingMargin
public int getLeadingMargin (boolean first)
Returns the amount by which to adjust the leading margin. Positive values move away from the leading edge of the paragraph, negative values move towards it.
Parameters | |
---|---|
first |
boolean : true if the request is for the first line of a paragraph,
false for subsequent lines |
Returns | |
---|---|
int |
the offset for the margin. |
getSpanTypeId
public int getSpanTypeId ()
Return a special type identifier for this span class.
Returns | |
---|---|
int |
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 |
