Facebook android 登录

Question

在下面的代码中，我使用的是 facebook 提供的 chrome 自定义标签功能， facebook 登录屏幕在 chrome（如果设备具有 chrome 浏览器）或简单的 webview 以及在 facebook 应用程序（如果设备具有应用程序）中打开，但在授予一般权限后 graphapi 甚至不提供任何数据在异步调用之后我没有得到我在这方面做错了什么请尽可能提供帮助

额外信息：- 这是在片段内调用，Facebook 登录屏幕以所有三种方式打开，只是回调不起作用，直到现在我无法找到解决方案，只能得到未答复问题是，我们可以就此联系 Facebook 的任何方式。

gradle 依赖关系

    compile 'com.facebook.android:facebook-android-sdk:[4,5)'

Answer 1

终于找到解决办法了。好吧，当您在片段中执行此操作时，您必须

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    fragment.onActivityResult(requestCode,resultCode,data);
}

在 activity 中，因为这个 sdk 触发，在 activity 中，你必须从他们那里将它传递给你的片段（用你的 loginfragment 替换片段）
