Answer 1

如果您以前的状态是活动，则在onClick的取消按钮上，意图使用先前的活动，否则仅将onClick函数保留为空白将起到保持相同活动的作用。

Answer 2

place dialog.cancel in negative button code

.setNegativeButton("No", new DialogInterface.OnClickListener() {
               public void onClick(DialogInterface dialog, int id) {
                    dialog.cancel();
               }
           });

Answer 3

on click on cancel button you need to save the default settings.

create a method to set default setting and call that method onclick of cancel button

Sample Code

.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int whichButton) {
                       saveDefaultSettings(); //this method sets the default settings of tha app                                    
                }
            })
