我為 Toothpick 和 Authenticator 創(chuàng)建了 Activity、ViewModel、Modules。@Singletonpublic class GetSmsViewModel {    @Inject Application app;    @Inject Authenticator authenticator;...}public class GetSmsActivity extends AppCompatActivity {    private Scope appScope;    @Inject GetSmsViewModel mGetSmsViewModel;...    @Override    protected void onCreate(Bundle savedInstanceState) {        appScope = Toothpick.openScope(getApplication());        appScope.installModules(new DIModule(getApplication()), new DataModule());        super.onCreate(savedInstanceState);        Toothpick.inject(this, appScope);   ...   }}public class DIModule extends Module {    public MagicDeliveryMainModule(Application application) {        bind(GetSmsViewModel.class).toInstance(new GetSmsViewModel());        bind(Application.class).toInstance(application);        bind(Authenticator.class).toInstance(new Authenticator());    }}在 Toothpick 的文檔中寫道：“如果 Toothpick 創(chuàng)建一個(gè)實(shí)例，它將始終注入其依賴項(xiàng)?！?, 但在 Toothpick.inject(this, appScope); 之后mGetSmsViewModel.app == null 和 mGetSmsViewModel.authenticator == null 。在 Toothpick.inject(mGetSmsViewModel, appScope); 之后 app 和 authenticationator 字段被注入。應(yīng)該是這樣嗎？
