การสร้าง DialogBox ออกจากแอพ
1. ไปที่เมนู Code เลือก Override methods
2. ค้นหา onBasePressed()และเพิ่มคำสั่งดังตัวอย่าง

== Code Example ==
@Override
public void onBackPressed() {
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("Exit App");
alert.setMessage("Are you sure want to exit?");
alert.setCancelable(false);
alert.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
finish();
}
});
alert.setNegativeButton("No", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {

}
});
AlertDialog alertDialog = alert.create();
alertDialog.show();
}
