我已经向 Android 应用程序添加了共享功能，如此处所述https://developers.facebook.com/docs/android/share-dialog/#setup

但我注意到，如果用户被取消onComplete，无论如何都会调用共享活动

@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!");
        }
    });
}

我还查看了返回的 Bundle。即使我取消共享对话框，我也会得到

com.facebook.platform.extra.DID_COMPLETE=true

如何获得用户真正在 facebook 上共享数据的结果？（无需使用 facebook 按钮单独登录。也许需要添加一些权限？）

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

您可以通过调用来判断用户是否已取消

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 data 是结果包。但是，如果用户已通过您的应用程序登录（即您至少具有 basic_info 权限），它只会返回非空值。如果用户从未登录或授权您的应用程序，那么您将看到的唯一内容是 DID_COMPLETE，除非发生错误，否则它将始终为真。这是设计使然。

要获取分享结果，您的应用至少需要具有 basic_info 权限。

要解决这个问题，只需打开一个会话（这将自动请求 basic_info 权限）：

Session.openActiveSession(this /*your activity*/, 
                          true /*allows the UI login to show up if needed*/, 
                          new Session.StatusCallback() {
    @Override
    public void call(Session session, SessionState state, Exception exception) {
        Log.i("[Facebook]", "Session: " + state.toString());
        if (session.isOpened()) {
           /// now you are good to get the sharing results
        }
    }
});

@Override
public void onComplete(FacebookDialog.PendingCall pendingCall, Bundle data) {
    if (data.getString("com.facebook.platform.extra.COMPLETION_GESTURE").equals("cancel"))
        return;
}

data.getString("com.facebook.platform.extra.COMPLETION_GESTURE")当用户在 Facebook 上发帖时，的值为“post”。

实施FacebookCallback<Sharer.Result>以了解共享是否成功或取消或有错误。

您也可以在 Activity 和 Fragment 中使用下面的代码。在 Fragment 中使用时，请确保传入thisShareDialog 构造函数。如果你通过了getActivity()，那么onActivityResult方法将不会在 Fragment 中被触发。

private CallbackManager callbackManager;

private void shareYourContentOnFacebook() {

    callbackManager = CallbackManager.Factory.create();
    ShareDialog shareDialog = new ShareDialog(this);
    shareDialog.registerCallback(callbackManager, new FacebookCallback<Sharer.Result>() {
        @Override
        public void onSuccess(Sharer.Result result) {
            Log.d(this.getClass().getSimpleName(), "shared successfully");
            //add your code to handle successful sharing
        }

        @Override
        public void onCancel() {
            Log.d(this.getClass().getSimpleName(), "sharing cancelled");
            //add your code to handle cancelled sharing

        }

        @Override
        public void onError(FacebookException error) {
            Log.d(this.getClass().getSimpleName(), "sharing error");
            //add your code to handle sharing error

        }
    });

    if (ShareDialog.canShow(ShareLinkContent.class)) {

        ShareLinkContent shareLinkContent = new ShareLinkContent.Builder()
                .setContentTitle("Your content title")
                .setContentDescription("Your content description")
                .setContentUrl(Uri.parse(""http://your-content-url.com""))
                .build();

        shareDialog.show(shareLinkContent);

    }

}

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

使用此代码：-

/**
 * Facebook Dialog Callback 
 * 
 * Called up when come back from Share Dialog
 * 
 */
private class FacebookDialogCallBack implements FacebookDialog.Callback
{
    @Override
    public void onComplete(PendingCall pendingCall, Bundle data) 
    {
        //Show Toast Message
        showToastMessage(data);
    }

    @Override
    public void onError(PendingCall pendingCall, Exception error, Bundle data) 
    {
        //Show Toast Message
        showToastMessage(data);
    }
}
//Show Toast Message
private void showToastMessage(Bundle data)
{
    //Get Native Dialog Did Complete
    boolean didComplete = FacebookDialog.getNativeDialogDidComplete(data);

    if(didComplete)
    {
        //Get Native Dialog Completion Gesture
        String nativeDialogCompletionGesture = FacebookDialog.getNativeDialogCompletionGesture(data);

        if (nativeDialogCompletionGesture == null || FacebookDialog.COMPLETION_GESTURE_CANCEL.equals(nativeDialogCompletionGesture))
        {
            //Show Publish Cancel Toast
            UIUtil.showToast(R.string.toast_message_share_publish_cancelled);                                               
        }
        else
        {
            //Show Success Post Toast
            UIUtil.showToast(R.string.toast_message_share_success_post);
        }
    }
    else
    {
        //Show Publish Cancel Toast
        UIUtil.showToast(R.string.toast_message_share_publish_cancelled);
    }
}
