ProgressDialog的dismiss方法与cancel方法的区别

（转载）/article/2884965.html

上一篇博客AsyncTask的用法有一个ProgressDialog，它有两个方法dialog.cancel() 和pdialog.dismiss();

都是取消关闭ProgressDialog，有什么区别吗？

查询API文档，ProgressDialog继承于Dialog，而cancel和dismiss就是在Dialog类中。

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).

取消对话框，基本上和调用dismiss效果一样。但是cancel同事也会调用

DialogInterface.OnCancelListener注册的事件，如果注册了。

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()

.
