NumberSpan

public NumberSpan(int blockMargin,
 int color,
 String number)

Method Details

measure

public static void measure(@NonNull
 TextView textView,
 @NonNull
 Spanned markdown)

Process supplied `text` argument and supply TextView paint to all NumberSpans in order for them to measure number.

NB, this method must be called before setting text to a TextView (`TextView#setText` internally can trigger new Layout creation which will ask for leading margins right away)

Parameters:

textView - to which markdown will be applied

markdown - parsed markdown to process

getLeadingMargin

public int getLeadingMargin(@NonNull
 TextPaint paint,
 boolean first)

Description copied from interface: LeadingMarginSpan

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.

The leading margin is on the left for lines in a left-to-right paragraph, and on the right for lines in a right-to-left paragraph. The default implementation is to call LeadingMarginSpan.getLeadingMargin(boolean).

Added by Modern UI.

Specified by:

getLeadingMargin in interface LeadingMarginSpan

Parameters:

paint - the base paint (read-only)

first - true if the request is for the first line of a paragraph, false for subsequent lines

Returns:

the offset for the margin.

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

Specified by:

Parameters:

c - the canvas

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

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
