int : the indent for the first line of the paragraph |
rest |
int : the indent for the remaining lines of the paragraph |

---|---|
every |
int : the indent of each line |
LeadingMarginSpan.Standard (Parcel src)
Parameters | |
---|---|
src |
Parcel
|
int describeContents ()
描述此Parcelable实例的封送表示中包含的特殊对象的种类。 例如,如果对象在writeToParcel(Parcel, int)
的输出中包含writeToParcel(Parcel, int)
,则此方法的返回值必须包含CONTENTS_FILE_DESCRIPTOR
位。
Returns | |
---|---|
int |
a bitmask indicating the set of special object types marshaled by this Parcelable object instance. |

呈现领先优势。 这在保证金被getLeadingMargin(boolean)
返回的值调整之前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 |
int getLeadingMargin (boolean first)
返回调整前导余量的金额。 正值远离段落的前沿,负值趋向于它。
Parameters | |
---|---|
first |
boolean : true if the request is for the first line of a paragraph, false for subsequent lines |
Returns | |
---|---|
int |

Parameters | |
---|---|
dest |
Parcel : The Parcel in which the object should be written. |
flags |
int : Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE . |
