            final AlertDialog.Builder builder = new AlertDialog.Builder(this);

            builder.setMessage("this is message");
            builder.setTitle("this is title");

            //Setting message manually and performing action on button click
            builder.setMessage("Do you want to close this application ?");T
            //This will not allow to close dialogbox until user selects an option
            builder.setCancelable(false);
            builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int id) {
                            Toast.makeText(this, "positive button", Toast.LENGTH_SHORT).show();
                            //builder.finish();
                        }
                    });
             builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int id) {
                            //  Action for 'NO' Button
                            Toast.makeText(this, "negative button", Toast.LENGTH_SHORT).show();
                            dialog.cancel();
                        }
                    });

            //Creating dialog box
            AlertDialog alert = builder.create();
            //Setting the title manually
            //alert.setTitle("AlertDialogExample");
            alert.show();
