如何获取接口内的方法的签名？

Question

I have a class named Fruits. Inside the class there is a interface named Sour. Inside the Interface I have a method GetItems();

public class Fruits
{
    ----------------
    ----------------
    public interface Sour
    {
        public int GetItems();
    }
}

How to get the signature of the GetItems() method?. I want to use this signature in JNI GetMethodID method.

Answer 1

Some class has to first implement that interface.

Once a class has imlpemented an interface then you should be able to get the methodID for the interface method, which is now a member of the class that implemented it.

Answer 2

You can't use JNI without a class implementing your Interface. Just use the signature of this implementing class.
