Android：指纹认证使用web登录

Question

我的应用程序有一个 webview 登录，并通过它结合了指纹识别。 我想在指纹认证成功后，我想继续我的指纹登录，就像我输入 email 和密码时的登录过程一样。

因此，这是 onEvent 方法，在该方法中，在指纹身份验证时，它将进入我希望 go onPageFinished 或 WebViewClient 方法的 if 条件：

onEvent 方法（指纹）：

private FingerprintAlertDialogFragment fingerprintAlertDialogFragment = new FingerprintAlertDialogFragment();
public EventListener<FingerprintAlertDialogFragmentEvent> onFingerprintAlertDialogFragmentEvent = new EventListener<FingerprintAlertDialogFragmentEvent>() {
    @Override
    public void onEvent(FingerprintAlertDialogFragmentEvent event) {
        if (event.getDialogType() == FingerprintAlertDialogFragment.DialogType.FINGERPRINT_RECOGNITION_LOGIN) {

            if (fingerprintAlertDialogFragment.isSuccessFingerPrintAuth()) {
                //how will I call the onpagefinished in this condition?
                return;
            }

            if (!fingerprintAlertDialogFragment.isSuccessFingerPrintAuth() && fingerprintAlertDialogFragment.hasFingerprintFailed()) {
                showGenericFingerPrintErrorMessage();
                return;
            }

            if (event.getClickedButtonType() == FingerprintAlertDialogFragmentEvent.ClickedButtonType.POSITIVE) {
                return;
            }

        }
    }
};

这是我的 WebViewClient 方法：

    private WebViewClient webViewClient = new WebViewClient() {
    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon) {
        VALogger.d(">>>", "started " + url);
        super.onPageStarted(view, url, favicon);
    }

    @SuppressWarnings("deprecation")
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        handleUrl(url);
        return super.shouldOverrideUrlLoading(view, url);
    }

    @RequiresApi(Build.VERSION_CODES.N)
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
        handleUrl(request.getUrl().toString());
        return super.shouldOverrideUrlLoading(view, request);
    }

    private void handleUrl(String url) {
        VALogger.d(">>>", "handleUrl: " + url);
        if (url.toUpperCase().startsWith(BuildConfig.LOGIN_REDIRECT_URI.toUpperCase())) {
            Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
            startActivity(intent);
            getActivity().finish();
            webView.setVisibility(View.GONE);
        }
    }

    @SuppressLint("NewApi")
    @Override
    public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) {
        super.onReceivedError(view, request, error);
        setGenericErrorMessage(view, "Generic Error: " + error.getDescription().toString());
    }

    @Override
    public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
        super.onReceivedError(view, errorCode, description, failingUrl);
        setGenericErrorMessage(view, "Unable to Connect to: " + failingUrl);
    }

    @Override
    public void onPageFinished(WebView view, String url) {
        super.onPageFinished(view, url);
        processLoginClick(); //fingerprint dialog will show
        //if (url.contains("oauth/redirect?code=")){
          //  handleUrl(url);
        //}
    }
};

webview 客户端方法中的 handleUrl 方法负责登录目的。 我将如何使用指纹认证？ 请帮我。 谢谢！
