在Android Studio 3中渲染Google Recaptcha

Question

我正在使用Android Studio 3

我正在关注这篇文章,以了解如何在Android Studio中使用Google Recaptcha.

使用以下方法安装包: implementation 'com.google.android.gms:play-services-safetynet:12.0.1'

API密钥也已注册.

我看到有onClick事件处理程序但它在哪里提到了渲染recaptcha？

当我写链接中提到的按钮单击代码时...我得到了一个复杂的错误:无法转换的类型无法将匿名的android.view.view.onclicklistener强制转换为java.util.concurrent.executor

代码在评论中提出

btn_Login.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(final View view) {
        SafetyNet.getClient(this).verifyWithRecaptcha("")
            .addOnSuccessListener((Executor) this,
                new OnSuccessListener<SafetyNetApi.RecaptchaTokenResponse>() {
                    @Override
                    public void onSuccess(SafetyNetApi.RecaptchaTokenResponse response) {
                        // Indicates communication with reCAPTCHA service was
                        // successful.
                        String userResponseToken = response.getTokenResult();
                        if (!userResponseToken.isEmpty()) {
                            // Validate the user response token using the
                            // reCAPTCHA siteverify API.
                        }
                    }
                })
            .addOnFailureListener((Executor) this, new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    if (e instanceof ApiException) {
                        // An error occurred when communicating with the
                        // reCAPTCHA service. Refer to the status code to
                        // handle the error appropriately.
                        ApiException apiException = (ApiException) e;
                        int statusCode = apiException.getStatusCode();

                    } else {
                    }
                }
            });
    }
});

我使用了下面的代码，现在一切正常。

确保在活动中实现Executor

btn_Login.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(final View view) {
        SafetyNet.getClient(Activity.this).verifyWithRecaptcha("")
            .addOnSuccessListener((Activity) MyActivity.this,
                new OnSuccessListener<SafetyNetApi.RecaptchaTokenResponse>() {
                    @Override
                    public void onSuccess(SafetyNetApi.RecaptchaTokenResponse response) {
                        // Indicates communication with reCAPTCHA service was
                        // successful.
                        String userResponseToken = response.getTokenResult();
                        if (!userResponseToken.isEmpty()) {
                            // Validate the user response token using the
                            // reCAPTCHA siteverify API.
                        }
                    }
                })
            .addOnFailureListener((Activity) MyActivity.this, new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    if (e instanceof ApiException) {
                        // An error occurred when communicating with the
                        // reCAPTCHA service. Refer to the status code to
                        // handle the error appropriately.
                        ApiException apiException = (ApiException) e;
                        int statusCode = apiException.getStatusCode();

                    } else {
                    }
                }
            });
    }
});
