Hi there,
I find the Notepad tutorial to be anything but simple for me. Could
someone tell me in the code below why you call super immediately in
method 1 and then last in method 2? I had thought that if you're
going to call super,you had to do it immediately (or is that only with
a constructor but not with a method)?
Also, if you return true in method 2, does that mean that super is
never called b/c you exit the switch statement immediately? If you do
exit, then you're not chaining up to the superclass' method, which I
thought you always want to do. I'm not even sure what the superclass'
onOptionsItemSelected() does anyway. Does everyone understand every
line of code or should I just stop trying to analyze what every
parameter means and just sort of follow a formula? I guess that I am
finding Android extremely hard to understand from the documentation.
METHOD 1
@Override
public boolean onCreateOptionsMenu(Menu menu) {
boolean result = super.onCreateOptionsMenu(menu);
menu.add(0, INSERT_ID, 0, R.string.menu_insert);
return result;
}
METHOD 2
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case INSERT_ID:
createNote();
return true;
}
return super.onOptionsItemSelected(item);
}
Thanks!
