如何使用MVP将服务层消息/错误传递给更高层？

public interface OnMessageListener {
    void onSuccess(String message);
    void onError(String errorMessage);
}

public class MyModel {
    private OnMessageListener onMessageListener;

    public void setOnMessageListener(OnMessageListener onMessageListener) {
        this.onMessageListener = onMessageListener;
    }

    public void doSomething() {
        // 处理业务逻辑
        if (success) {
            onMessageListener.onSuccess("操作成功");
        } else {
            onMessageListener.onError("操作失败");
        }
    }
}

public class MyPresenter {
    private MyModel myModel;
    private MyView myView;

    public MyPresenter(MyModel myModel, MyView myView) {
        this.myModel = myModel;
        this.myView = myView;
        myModel.setOnMessageListener(new OnMessageListener() {
            @Override
            public void onSuccess(String message) {
                myView.showMessage(message);
            }

            @Override
            public void onError(String errorMessage) {
                myView.showError(errorMessage);
            }
        });
    }

    public void doSomething() {
        myModel.doSomething();
    }
}

public class MyView {
    public void showMessage(String message) {
        // 显示成功消息
    }

    public void showError(String errorMessage) {
        // 显示错误消息
    }
}
