使用Android中的Facebook SDK共享对话框。如何知道是用户实际共享或取消共享活动？

问题描述

我添加了分享功能，如这里所描述的Andr​​oid应用程序，https://developers.facebook.com/docs/android/share-dialog/#setup

I have added sharing functionality to Android app as described here https://developers.facebook.com/docs/android/share-dialog/#setup

不过，我已经注意到，如果用户被取消分享活动的onComplete反正是名为

But I have noticed that if user is cancelled sharing activity onComplete is called anyway

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

    uiHelper.onActivityResult(requestCode, resultCode, data, new FacebookDialog.Callback() {
        @Override
        public void onError(FacebookDialog.PendingCall pendingCall, Exception error, Bundle data) {
            Log.e("Activity", String.format("Error: %s", error.toString()));
        }

        @Override
        public void onComplete(FacebookDialog.PendingCall pendingCall, Bundle data) {
            Log.e("Activity", "Success!");
        }
    });
}

我也期待在捆绑被返回。即使我删除共享对话框我得到

I have also looked in to Bundle which is returned. Even if I cancel share dialog i get

com.facebook.platform.extra.DID_COMPLETE=true

我怎样才能得到该用户在Facebook真的共享数据？ （未做单独的登录与Facebook按钮，也许需要一些权限被添加？）

How can I get result that user really shared data on facebook? (Without making separate login with facebook button. Maybe some permissions need to be added?)

推荐答案

请参阅https://developers.facebook.com/docs/android/share-dialog/#handling-responses

您可以告诉用户是否已经取消了通过调用

You can tell if the user has cancelled by calling

String gesture = FacebookDialog.getNativeDialogCompletionGesture(data);
if (gesture != null) {
  if ("post".equals(gesture)) {
    // the user hit Post
  } else if ("cancel".equals(gesture)) {
    // the user hit cancel
  } else {
    // unknown value
  }
} else {
  // either an error occurred, or your app has never been authorized
}

其中，数据的结果包。但是，如果用户通过您的应用程序登录，它只会返回一个非空值（即至少有basic_info权限）。如果用户从未登录过或授权您的应用程序，那么你将看到的唯一的事情就是DID_COMPLETE，它永远是真实的，除非发生了错误。这是由设计。

where data is the result bundle. However, it will only return a non-null value IF the user has logged in via your app (i.e. you have at least basic_info permissions). If the user has never logged in or authorized your app, then the only thing you'll see is the DID_COMPLETE, and it will always be true unless an error occurred. This is by design.
