DAGGER：尝试注入 Fragment 时无法解决错误 "this"？

Question

我在这一行收到 "cannot resolve method" 错误：

AndroidInjection.inject(this);

我正在尝试注入片段。这是整个class:

public class ShowWalletFragment extends BaseFragment {

    @Inject
    ShowWalletViewModelFactory showWalletViewModelFactory;
    ShowWalletViewModel showWalletViewModel;
    private Wallet wallet;
    private static final String TITLE_BALANCE = "Balance";

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        return super.onCreateView(inflater, container, savedInstanceState);
        //butterknife bind
    }

    @Override
    public void onActivityCreated(@Nullable Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        showWalletViewModel = ViewModelProviders.of(this, showWalletViewModelFactory).
                get(ShowWalletViewModel.class);
    }

    @Override
    public void onAttach(Context context) {
        AndroidInjection.inject(this);
        super.onAttach(context);
    }

}

为什么不能解析 "this"？有什么建议么？如果您需要我的应用程序的更多代码，请告诉我。
