在Android Facebook SDK中使用共享对话框。如何知道用户是否实际分享或取消共享活动？ [英] Using share dialog in Android Facebook SDK. How to know is user actually shared or cancelled sharing activity?

问题描述

我已按照 https：//这里所述为Android应用添加了共享功能developers.facebook.com/docs/android/share-dialog/#setup

但是我注意到，如果用户被取消共享活动，则完全被调用

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!");
        }
    });
}

我还查看了Bundle返回的内容。即使我取消共享对话框，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

如何获取用户真正在Facebook上共享数据的结果？ （没有使用Facebook按钮进行单独登录，也许需要添加一些权限？）

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

您可以通过调用

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
}

其中数据是结果束。但是，如果用户已通过您的应用程序登录（即，您至少拥有basic_info权限），它将只返回非空值。如果用户从未登录过或授权您的应用程序，那么您唯一可以看到的是DID_COMPLETE，除非发生错误，否则它始终为真。这是设计的。

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.
