如何在Kotlin中将变量从内部类检索到函数

Question

我正在尝试从内部类Adapter检索testvar值到addtocart函数，但没有得到该值。我可以在Adapter类内检索值，但不能在类外检索值。         代码：

dominic@dom-Inspiron-7559:~/Desktop/Projects/stemletics/stemletics/mysite$ grunt watch
Running "watch" task
Waiting...
>> File "mysite/static/sass/_video.scss" changed.
Running "sass:dist" (sass) task

Done.

以为您希望在RecyclerView中放置一个按钮。

在这种情况下

内的setOnclicklistener

export class NavbarComponent implements OnInit {

    public loggedIn: boolean;
    public user: any;

    constructor(private _authService: AuthService, private _router: Router) { }

    ngOnInit() {
        this._authService.authStatus
            .subscribe(
                value => {
                    this.loggedIn = value

                }
            );
    }
