        }
}

I'm a novice at JAVA, but i get this error message at line 29, on the "department" line.

Cannot switch on a value of type EditText. Only convertible int values or enum constants are permitted.

I'm not sure how to fix this. Any takers?

Learn some actual java, before writing code. You'll save yourself a lot of trouble. — JoxTraex, Apr 25 '12 at 07:40
You had posted the same question yesterday I believe! Try and learn something and find out the errors for yourself! Instead of just hoping for people spoon-feeding you! — Kazekage Gaara, Apr 25 '12 at 07:52
I put it into google, and got nothing. I'd learn more of it myself, but i have a project for it due in a week and the teacher never taught us the language. — user1338942, Apr 25 '12 at 14:28

In Java 6, switch takes only int or enum. If you want to take the text from the EditText, convert it to int, and use it on switch, then you can do something like this:

switch(Integer.parseInt(department.getText().toString())) // Be careful! This could throw an exception if the text doesn't contain a valid integer

It would make sense also to ensure that `android:inputType="number"` is set on the EditText field, see ["how to return an int from EditText"](http://stackoverflow.com/questions/4903515/how-do-i-return-an-int-from-edittext-android) – Dima Chubarov Apr 25 '12 at 07:45

department is not an int or enum value, so it cannot be switched on.

As the error suggests, you can't pass an entire object to your switch statement and expect it to work. You need something which by the end of the day will resolve to an integer value.

You could have some method in your EditText class which would return some integer, then, you could do something like switch(departement.getNumericalValue()) and use switch to work on that, but other than that, you can't work with what you currently have.

As of Java 7, you can switch of Strings, but not on standard Objects

http://docs.oracle.com/javase/tutorial/java/nutsandbolts/switch.html

However, you are using android and hence still java 6

Since you have to use 6, you'll need to convert the String to an integer

switch (Integer.parseInt(department.getText())){
    case 1:
         display = "food";
....

You can't use Java 7 features in Android http://stackoverflow.com/questions/7153989/java-7-language-features-with-android – zapl Apr 25 '12 at 07:51
Thanks Zapl, perhaps I should not have led with the whole 7 has strings sentence, i did say however Android uses 6. I've now changed the "however" to get a bit more emphasis. I assumed the poster was confused between 7 and 6 features which is why i mentioned it – Bruce Lowe Apr 25 '12 at 08:10

I was thinking that too & therefore +1 your answer – zapl Apr 25 '12 at 08:19

You should use getText to get the text value from your EditText field and convert it to numeric values..

Replace the switch statement on the department variable by a switch statement on

Integer.parseInt(department.getText().toString())
