Android facebook 4.0.0共享对话框不共享内容

Question

几个小时我一直试图通过facebook 4.0.0 sdk在我的Android应用程序中共享内容。 我完全按照facebook分享文件但没有结果。 当我按分享按钮但没有内容时，共享对话框打开。 如果我单击确定它只是共享一个空字符串。 请告诉我一个解决这个问题的方法。

BTW当我从手机中删除Facebook原生应用程序时，我可以与facebook的webview分享。

CallbackManager callbackManager;
    ShareDialog shareDialog;
    private View rootView;
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        FacebookSdk.sdkInitialize(activity);
        callbackManager = CallbackManager.Factory.create();
        shareDialog = new ShareDialog(activity);
        rootView = inflater.inflate(R.layout.fragment_events, container, false);

        shareDialog.registerCallback(callbackManager, shareCallBack);

        lbtnShare        = (LinearLayout) rootView.findViewById(R.id.lbtn_shareOnFb); 
        lbtnShare.setOnClickListener(this);

        init(rootView);
        return rootView;
    }

            shareDialog.show(adShareContent);
        }
    }

@Override

        super.onActivityResult(requestCode, resultCode, data);
        callbackManager.onActivityResult(requestCode, resultCode, data);
    }

Answer 1

您需要使用您所在的片段（此）创建ShareDialog，而不是活动。 onActivityResult会在写入时返回给活动，因此它不会进入回调管理器。

我发布这个答案是因为Gabby希望在那里分享我的代码。

这是我的MainActivity.java;

public class MainActivity extends ActionBarActivity implements ActionBar.TabListener {

我有一个CustomShareActionProvider类，它帮助我检测用户点击事件。 如果用户点击Facebook上的共享按钮，则会打开ShareDialog。

这是我的CustomShareActionProvider.class：

    mOnShareListener = listener;
    setActivityChooserPolicyIfNeeded();

     *     any changes to the latter will be ignored.
     * </p>
     * <p>
     * <strong>Note:</strong> You should <strong>not</strong> handle the

你的代码在onError（）方法中是个例外吗？ 消息是“未找到应用程序名称”。 如果正确，你需要在清单中添加代码： <meta-data android:name="com.facebook.sdk.ApplicationName" android:value="@string/facebook_app_name" />

您需要在Facebook开发者网站上将string.xml中的app_name编辑为相同的应用程序名称。

我不确定这是不是你的问题，但我的分享对话在facebook上总是空的。 为了解决这个问题，我刚刚更改了.setContentUrl。 如果您将链接添加到Google Play或应用商店，则只会清空对话框，因此您应将其更改为任何其他链接。
