Is there a way to define a protocol class in Android?

Question

I am new to Android and have been working on iOS for the longest time. Just ask the basic question regarding the protocol class. Here is my protocol class in iOS:

#import "ServiceBaseProtocol.h" #import "ServiceTasksProtocol.h" @protocol AnswersServiceProtocol <ServiceBaseProtocol> - (NSUInteger)answersQueryIntentForTarget:(id<ServiceTaskCallbackProtocol>)target requestInput:(NSString*)requestInput; @end 

Is it possible to convert this to equivalent android code. How do I get along?

Answer 1

Protocols are called interfaces in Java. So your code snippet might look like this:

  public interface AnswersServiceProtocol extends ServiceBaseProtocol { public int answersQueryIntentForTargetAndRequestInput(ServiceTaskCallbackProtocol target, String requestInput); }
