dialog box

OK Cancel dialog box

Create a Dialog Builder object, similar to Factory mode

        Alertdialog.builder Builder =  Builder ();

Set the title and body

        Builder ()
        Builder ()

Set OK and Cancel buttons

        Builder.setpositivebutton (,  Onclicklistener () {

            
              (Dialoginterface dialog,  which) {
                
                Toast.maketext (mainactivity.,,). Show ();
            }
        );

        Builder.setnegativebutton (,  Onclicklistener () {

            
              (Dialoginterface dialog,  which) {
                
                Toast.maketext (mainactivity.,,). Show ();
            }
        );

To create a dialog object using the Builder

        Alertdialog ad = Builder. ();
        Ad. ();

Radio dialog box

        Alertdialog.builder Builder =  Builder ();
        Builder.settitle ();

Define a single selection option

         string[] items =  string[]{
                ,, 
        };
        
        
        Builder.setsinglechoiceitems (items,-,  Onclicklistener () {

            
            
              (Dialoginterface dialog,  which) {
                Toast.maketext (mainactivity.,  + Items[which],). Show ();
                
                Dialog.dismiss ();
            }
        );

        Builder.show ();

Multi-selection dialog box

        Alertdialog.builder Builder =  Builder ();
        Builder.settitle ();

Define multiple selections because you can select more than one, so you need a Boolean array to record which options are selected

 string[] items = string[]{,,,
        
         };
        [] CheckedItems = []{,,,,};

            
            
              Builder.setmultichoiceitems (items, CheckedItems, Onmultichoiceclicklistener () { (Dialoginterface dialog, which, ischecked)
            {Checkeditems[which] = ischecked;

        }
        });
                Builder.setpositivebutton (, Onclicklistener () {(Dialoginterface dialog, which) {
                StringBuffer sb = StringBuffer (); (i =; i < items.length; i++)
                {sb.append (checkeditems[i]? Items[i] +:);
            } toast.maketext (mainactivity., sb.tostring (),). Show ();
        }
        }); Builder.show ();
