Parameters:

paint - the paint used for measuring the text

getLeadingMargin

public int getLeadingMargin(boolean first)

Specified by:

getTrailingMargin in interface TrailingMarginSpan

Returns:

the offset for the margin.

drawLeadingMargin

public void drawLeadingMargin(Canvas c,
 TextPaint p,
 int x,
 int dir,
 int top,
 int baseline,
 int bottom,
 CharSequence text,
 int start,
 int end,
 boolean first,
 Layout layout)

Description copied from interface: LeadingMarginSpan

Renders the leading margin. This is called before the margin has been adjusted by the value returned by LeadingMarginSpan.getLeadingMargin(boolean).

Specified by:

drawLeadingMargin in interface LeadingMarginSpan

Parameters:

c - the canvas

p - the paint. This should be left unchanged on exit.

x - the current position of the margin

dir - the base direction of the paragraph; if negative, the margin is to the right of the text, otherwise it is to the left.

top - the top of the line

baseline - the baseline of the line

bottom - the bottom of the line

text - the text

start - the start of the line

end - the end of the line

first - true if this is the first line of its paragraph

layout - the layout containing this line

drawMargin

public void drawMargin(Canvas c,
 TextPaint p,
 int left,
 int right,
 int dir,
 int top,
 int baseline,
 int bottom,
 CharSequence text,
 int start,
 int end,
 boolean first,
 Layout layout)

Description copied from interface: LeadingMarginSpan

Called when drawing the margin.

The default implementation is to call LeadingMarginSpan.drawLeadingMargin(icyllis.modernui.graphics.Canvas, icyllis.modernui.text.TextPaint, int, int, int, int, int, java.lang.CharSequence, int, int, boolean, icyllis.modernui.text.Layout), where x is either left or right, depending on dir. This method allows to draw the trailing margin at the same time, not just the leading margin.

c - the canvas

p - the paint. This should be left unchanged on exit.

left - the current left position of the margin

top - the top of the line

baseline - the baseline of the line

bottom - the bottom of the line
