我是新来的在Android Facebook的API，基本上，我想要做的是为我开发一个应用程序中创建自定义的墙后。 当你听一个Shazam的一首歌曲，你可以分享的结果与你的朋友喜欢。 我相信我一定要创建一个自定义的附件。这是我的code设置附件：

I'm new to Facebook API on Android, and basically, what I'm trying to do is creating custom wall post for an application I'm developing. Like when you listen a Shazam a song and you can share the result with your friends. I believe I've got to create a custom attachment. Here's my code for setting the attachment:

mPostButton.setOnClickListener(new OnClickListener() {

    public void onClick(View v) {
        Bundle myParams = new Bundle();
        String attachment="{\"name\":\"Gran Turismo 5\"," +
           "\"href\":\"http://www.unknown.com/?lang=fr\"," +
           "\"caption\":\"Sony Computer Entertainment\",\"description\":" +
           "\"Une vidéo proposée par Cedemo.\",\"media\":" +
           "[{\"type\":\"image\",\"src\":" +
           "\"https://m.xsw88.com/allimgs/daicuo/20230906/1264.png.jpg\"," +
           "\"href\":\"http://www.unknown.com/?lang=fr\"}],\"properties\":" +
           "{\"Autre lien\":{\"text\":\"Cedemo\",\"href\":\"http://www.unknown.com\"}}}";
        myParams.putString("attachment", URLEncoder.encode(attachment);
        mFacebook.dialog(Option.this, "stream.publish",myParams,
                new SampleDialogListener());

然后，后来就：

public class SampleDialogListener extends BaseDialogListener {

    public void onComplete(Bundle values) {
        final String postId = values.getString("post_id");
        if (postId != null) {
            Log.d("Facebook-Example", "Dialog Success! post_id=" + postId);
            mAsyncRunner.request(postId,values, new WallPostRequestListener());
        } else {
            Log.d("Facebook-Example", "No wall post made");
        }
    }
}

我不写的附件字符串，它只是一个试验，从本次论坛做了另一个问题所采取。无论如何，当我打电话myAsync.request，我的应用程序显示错误消息，我怎么打发依恋我的对话？ 希望我已经很清楚。

I didn't wrote the attachment String, It's just a test taken from another question made in this forum. Anyway, when I call myAsync.request, my app shows an error message, how am I supposed to pass the attachment to my dialog? Hope I've been clear enough.

推荐答案

您确定您需要设置自定义的参数？这听起来像你只是想直接上传Facebook的消息在墙上：您可以通过简单地交给在消息参数为一个字符串做到这一点 - 只有当您要附加的图像等，并注意需要所有的JSON在Facebook的页面，它说使用这个API调用将不会发布状态更新，其他人可以在他们的饲料看到，它只会出现在他们的自己的墙。如果你只是想发布一个链接的消息，你就应该能够使用您的mAsyncRunner（一旦你有你的有效的Facebook会话），使用这样的：

Are you sure you need to set custom parameters? It sounds like you can just want to post a Facebook message directly to the wall: you can do this by simply handing in the message parameter as a string -- you only need all that JSON if you want to attach an image etc. And note on facebook's page it says using this api call won't post a status update that others can see on their feed, it will just appear on their own wall. If you just want to post a message with a link you should just be able to use your mAsyncRunner (once you have your valid Facebook session) using this:

String message = "Post this to my wall";
Bundle parameters = new Bundle();        
parameters.putString("message", message);   
mAsyncRunner.request("me/feed", parameters, "POST", new WallPostRequestListener());

也可以帮助，如果您发布的错误/响应code你从Facebook获得。

Also may help if you posted the error/response code you're getting from Facebook.
