5.10 LineWidthDialogFragment Class

Class LineWidthDialogFragment (Fig. 5.48) extends DialogFragment to create an AlertDialog for setting the line width. The class is similar to class ColorDialogFragment, so we discuss only the key differences here. The class’s only instance variable is an ImageView (line 21) in which we draw a line showing the current line-width setting.
