android - 你可以发布从Facebook的SDK的状态更新？

Question

我只想发布一个Facebook的状态更新与Android的Facebook的SDK。 这可能吗？ 如果是这样，我该怎么办？

我已经看到了Facebook对话框教程，但是用于共享链接。

FacebookDialog shareDialog = new FacebookDialog.ShareDialogBuilder(this) 
      .setApplicationName("..").setLink("...").setCaption(",,,").setDescription("...").setName("..") 
      .build(); 
    uiHelper.trackPendingDialogCall(shareDialog.present()); 

但我可以发布一个简单的文本到我的脸谱墙吗？

Answer 1

https://developers.facebook.com/docs/graph-api/reference/v2.1/user/feed

搜索 “发布”，并点击 “Android的SDK” 的示例代码。但是要记住的是，信息必须根据政策产生100％的用户：

https://developers.facebook.com/policy/

2.3确保在用户消息参数的所有内容都是由用户输入。不要预先填写。这包括帖子，消息，评论， 和标题。

我用“publish_actions”登录，然后调用postToWall（）方法做了这个帖子。它为我工作。我正在使用Facebook的SDK。

//facebook 
compile 'com.facebook.android:facebook-android-sdk:4.18.0' 

public void postToWall() { 
     try { 

      GraphRequest request = GraphRequest.newPostRequest(AccessToken.getCurrentAccessToken(), "me/feed", null, new GraphRequest.Callback() { 
       @Override 
       public void onCompleted(GraphResponse response) { 
        Log.d("StatusPost", "STATUS UPDATED SUCESSFULLY " + response.getRawResponse()); 
       } 
      }); 
      Bundle parameters = new Bundle(); 
      parameters.putString("message", "hellow everyone from newyork"); 
      request.setParameters(parameters); 
      request.executeAsync(); 
     } catch (Exception e) { 
      e.printStackTrace(); 
      GlobalApp.printLog("Exception_feed", e.getMessage() + ""); 
      //finish(); 
     } 
    }
