如何连接 2 个 onActivityResult？

Question

我在添加 Facebook 身份验证时遇到问题，因为我也在使用 Google 身份验证，这就是我出错的原因

         public class SignUpActivity extends AppCompatActivity {
                callbackManager.onActivityResult(requestCode, resultCode, data);
                super.onActivityResult(requestCode, resultCode, data);
            //Google
            @Override
            public void onActivityResult(int requestCode, int resultCode, Intent data) {
                super.onActivityResult(requestCode, resultCode, data);

                // Result returned from launching the Intent from GoogleSignInApi.getSignInIntent(...);
                if (requestCode == RC_SIGN_IN) {
                    Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
                    try {
                        // Google Sign In was successful, authenticate with Firebase
                        GoogleSignInAccount account = task.getResult(ApiException.class);
                        firebaseAuthWithGoogle(account);
                    } catch (ApiException e) {
                        // Google Sign In failed, update UI appropriately
                        Log.w(TAG, "Google sign in failed", e);
                        // ...
                    }
                }
            }

            //and Facebook
            @Override
            protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            callbackManager.onActivityResult(requestCode, resultCode, data);
            super.onActivityResult(requestCode, resultCode, data);
    }

你怎么看我有两个 onActivityResult 方法。 有什么方法可以连接它们并消除错误吗？ 这就是我的错误

方法 onActivityResult(int,int,Intent) 已在类 SignUpActivity 中定义

它只是现有两种相同方法的交流。 谢谢。

onActivityResult是一个 Android 方法，它接收你从startActivityForResult开始的活动的结果，并返回你提供的 request_code int。

解决方案是在startActivityForResult使用不同的 REQUEST_CODES ，因此您可以在onActivityResult进行比较

喜欢：

private static final int FACEBOOK_REQUEST_CODE = 1;
private static final int GOOGLE_REQUEST_CODE = 0;

startActivityForResult(googleLoginIntent, GOOGLE_REQUEST_CODE)
startActivityForResult(facebookLoginIntent, FACEBOOK_REQUEST_CODE)

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == GOOGLE_REQUEST_CODE) {
        //do the code for google result
    } else if (requestCode == FACEBOOK_REQUEST_CODE) {
        // do the code for facebook result
    }
}
