StyleSpan

public class StyleSpan extends MetricAffectingSpan implements android.text.ParcelableSpan
Describes a style in a span. Note that styles are cumulative -- if both bold and italic are set in separate spans, or if the base style is bold and a span calls for italic, you get bold italic. You can't turn off a style from the base style.

Fields Summary
private final int
mStyle
Constructors Summary
public StyleSpan(int style)

param
style An integer constant describing the style for this span. Examples include bold, italic, and normal. Values are constants defined in {@link android.graphics.Typeface}.

		mStyle = style;
public StyleSpan(android.os.Parcel src)

        mStyle = src.readInt();
