DAGGER：尝试注入 Fragment 时，错误无法解决“这个”问题？

Question

我在这一行收到“无法解析方法”错误：

AndroidInjection.inject(this);

我正在尝试注入一个片段。这是整个班级：

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);
    }

}

为什么它不能解决“这个”？有什么建议？如果您需要我的应用程序中的更多代码，请告诉我。

用这个

import dagger.android.support.AndroidSupportInjection

AndroidSupportInjection.inject(this)
