android - Facebook 请求不等待用户输入

Question

我正在编写一个可以根据用户行为在 Facebook 上发布的应用程序。发布的过程是点击 FB 按钮，接下来应该发生的事情是 Facebook 尝试登录，如果用户已经登录，使用 SSO，它会创建一个 Facebook 对话框并将其发布到用户提要上.

但是，没有与用户的互动，帖子按原样发布在 Facebook 上。

如何提示常规移动应用程序用户交互以在 Facebook 上发布？

登录Facebook的代码:

public static final String appid = "1234567890";
public static final String[] permissions = { "publish_stream" };
Facebook facebook;

facebook.authorize(MyClass.this, permissions,
                new DialogListener() {

        @Override
        public void onComplete(Bundle values) {
            // control comes here if the login was successful
            // Facebook.TOKEN is the key by which the value of
            // access token is stored in the Bundle called
            // 'values'
            Log.d("COMPLETE", "AUTH COMPLETE. VALUES: "
                                + values.size());
            Log.d("AUTH TOKEN",
                    "== " + values.getString(Facebook.TOKEN));
            updateStatus(values.getString(Facebook.TOKEN));
        }

        @Override
        public void onFacebookError(FacebookError e) {
            Log.d("FACEBOOK ERROR", "FB ERROR. MSG: " + e.getMessage()
                    + ", CAUSE: " + e.getCause());
        }

        @Override
        public void onError(DialogError e) {
            Log.e("ERROR", "AUTH ERROR. MSG: " + e.getMessage()
                    + ", CAUSE: " + e.getCause());
        }

        @Override
        public void onCancel() {
            Log.d("CANCELLED", "AUTH CANCELLED");
        }
});

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Log.d("onActivityResult", "onActivityResult");
    facebook.authorizeCallback(requestCode, resultCode, data);
}

publishStream() 的代码:

protected void updateStatus(String accessToken) {
    try {
        Bundle msg = new Bundle();
        msg.putString("description", this.title);
        msg.putString("link", this.link);
        msg.putString("message", description);
        msg.putString(Facebook.TOKEN, accessToken);
        String response = facebook.request("me/feed", msg, "POST");
        Log.d("UPDATE RESPONSE", "" + response);
        Toast.makeText(SinglePost.this, "Posted on Facebook", Toast.LENGTH_SHORT).show();
    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (MalformedURLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

您正在使用 facebook.request() 方法，它会在后台静默发布您的消息。要显示对话框，您将使用 facebook.dialog() 方法。您的代码将如下所示:

facebook.dialog(context, "stream.publish", parameters, new SomeDialogListener());

SomeDialogListener 是 DialogListener 的子类，将是您处理来自 facebook 的响应的回调实例(与登录对话框的情况相同).
