Android™ How to Program, Second Edition

Overridden DialogFragment Method onCreateDialog

Method onCreateDialog (Fig. 7.35) inflates the custom View (lines 32–34) defined by fragment_color.xml containing the GUI for selecting a color, then attaches that View to the AlertDialog by calling AlertDialog.Builder’s setView method (line 35). Lines 42–50 get references to the dialog’s SeekBars and colorView. Next, lines 53–56 register colorChangedListener (Fig. 7.38) as the listener for the SeekBars’ events.
