public TextAppearanceSpan(android.content.Context context, int appearance)
Uses the specified TextAppearance resource to determine the text appearance. The appearance should be, for example, android.R.style.TextAppearance_Small.

        this(context, appearance, -1);
    
public TextAppearanceSpan(android.content.Context context, int appearance, int colorList)
Uses the specified TextAppearance resource to determine the text appearance, and the specified text color resource to determine the color. The appearance should be, for example, android.R.style.TextAppearance_Small, and the colorList should be, for example, android.R.styleable.Theme_textColorPrimary.

public TextAppearanceSpan(String family, int style, int size, android.content.res.ColorStateList color, android.content.res.ColorStateList linkColor)
