Paint paint)
Draws the span into the canvas.
| Parameters |
|---|
canvas |
Canvas:
Canvas into which the span should be rendered. |
text |
CharSequence:
Current text. |

int:
Start character index for span. |
end |
int:
End character index for span. |
x |
float:
Edge of the replacement closest to the leading margin. |
top |
int:
Top of the line. |
y |
int:
Baseline. |

int:
Bottom of the line. |

getSize
int getSize (Paint paint,
CharSequence text,
int start,
int end,
Paint.FontMetricsInt fm)
Returns the width of the span. Extending classes can set the height of the span by updating
attributes of Paint.FontMetricsInt. If the span covers the whole
text, and the height is not set,
draw(Canvas, CharSequence, int, int, float, int, int, int, Paint) will not be
called for the span.
| Parameters |
|---|
paint |
Paint:
Paint instance. |
text |
CharSequence:
Current text. |
start |
int:
Start character index for span. |
end |
int:

Paint.FontMetricsInt:
Font metrics, can be null. |
| Returns |
|---|
int |
Width of the span.
