不能把它扔到谷歌reCAPTCHA中的执行者

Question

我有一个问题与谷歌验证码。我正在使用他们 https://developer.android.com/training/safetynet/recaptcha#java 的例子，但是当我尝试转换到.thisExecutor

我得到的错误是：。com.johny.Aktivity.Activity cannot be cast to java.util.concurrent.Executor

我尝试了 impating，但后来 Android Studio 迫使我包含和 recapcha 总是在那里结束，而不是在 or 中。Executorexecute(Runnable)onSuccess()onFailure()

Answer 1

实际上，我不确定为什么在android开发人员网站上显示的代码不起作用，但是您可以尝试下面的代码，其中我只是对成功和失败的侦听器使用了不同的方法。&nbsp;SafetyNet.getClient(this).verifyWithRecaptcha("YOUR_API_SITE_KEY")&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; .addOnSuccessListener(new OnSuccessListener<SafetyNetApi.RecaptchaTokenResponse>() {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; @Override&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; public void onSuccess(SafetyNetApi.RecaptchaTokenResponse recaptchaTokenResponse) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // Indicates communication with reCAPTCHA service was&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // successful.&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; String userResponseToken = recaptchaTokenResponse.getTokenResult();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if (!userResponseToken.isEmpty()) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // Validate the user response token using the&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // reCAPTCHA siteverify API.&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Log.e(TAG, "VALIDATION STEP NEEDED");&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; })&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; .addOnFailureListener(new OnFailureListener() {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; @Override&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; public void onFailure(@NonNull Exception e) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if (e instanceof ApiException) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // An error occurred when communicating with the&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // reCAPTCHA service.
