In Android development, we often need to pop up some dialog boxes on the Android interface, such as asking the user or letting the user choose. These features we call it the Android Dialog dialog, in the process of using Android, I summed up, the android dialog type is no more than 7 kinds, I would like to introduce the 7 Kinds of Android Dialog dialog box to use the method, I hope we can be of some help.

Builder.setpositivebutton ("Confirm", new Onclicklistener () {  @Override public  void OnClick ( Dialoginterface dialog, int which) {  Dialog.dismiss ();  Main.this.finish ();  }
});
Builder.setnegativebutton ("Cancel", new Onclicklistener () {  @Override public  void OnClick (　　 Dialoginterface dialog, int which) {  Dialog.dismiss ();  }
});
