how to implement Handle,JniIdentityHashCode,PeerReference,JniPeerMembers,JniManagedPeerState on xama-CodePudding

Good day , how can I implement the functions below? on xamarin

  public IntPtr Handle => throw new NotImplementedException();

        public int JniIdentityHashCode => throw new NotImplementedException();

        public JniObjectReference PeerReference => throw new NotImplementedException();

        public JniPeerMembers JniPeerMembers => throw new NotImplementedException();

        public JniManagedPeerStates JniManagedPeerState => throw new NotImplementedException();

CodePudding user response：

Your C# object in the Android project should inherit from Java.Lang.Object.

public class YourCSharpObject : Java.Lang.Object
{
}

CodePudding user response：

In xamarin, if we implement interface, we need to inherit from class Java.Lang.Object as well as the interface itself,just as Trevor Balcom mentioned.

Suppose your interface is ITestClientListener,we can do like this:

public class TestClientListener : Java.Lang.Object, ITestClientListener
{
    public JniManagedPeerStates JniManagedPeerState()
    {
        throw new NotImplementedException();
    }

    IntPtr ITestClientListener.Handle()
    {
        throw new NotImplementedException();
    }

    int ITestClientListener.JniIdentityHashCode()
    {
        throw new NotImplementedException();
    }

    JniPeerMembers ITestClientListener.JniPeerMembers()
    {
        throw new NotImplementedException();
    }

    JniObjectReference ITestClientListener.PeerReference()
    {
        throw new NotImplementedException();
    }
}

And we can use it's instance like this:

//create a new object
TestClientListener listener = new TestClientListener();

// use it as you need

Note:

You need to add necessary codes in above methods in class TestClientListener .cs if it required.
