ProgressDialog的dismiss方法与cancel方法的区别

ProgressDialog，它有两个方法dialog.cancel() 和pdialog.dismiss();?都是取消关闭ProgressDialog，但它们有什么区别吗？

?

就是当使用cancel()的时候，则会同时调用你注册的DialogInterface.OnCancelListener()这个方法。以下是相关API的解释

?

public void cancel ()

Since: API Level 1

Cancel the dialog. This is essentially the same as calling dismiss(), but it will also call your DialogInterface.OnCancelListener (if registered).

public void dismiss ()

?

Since: API Level 1

?

Dismiss this dialog, removing it from the screen. This method can be

?

invoked safely from any thread. Note that you should not override this

?

method to do cleanup when the dialog is dismissed, instead implement

?

that in onStop().
