Cancel and Dismiss Custom dialog

Last article demonstrate a basic custom dialog, it can be dismissed by buttons. How about cancelled by system BACK key and touching outside dialog? by calling setCancelable(boolean) and setCanceledOnTouchOutside(boolean) we can sets whether this dialog is cancelable with the BACK key, and whether this dialog is canceled when touched outside the window's bounds.

We also implement OnCancelListener and OnDismissListener to handle the cancel and dismiss events.

Modify the main activity in the last article "Custom dialog, with data passed in Bundle".
