【问题描述】：

我正在尝试，但是当我调用共享功能（通过 SDK 或意图）时，我得到的只是没有文本的图像。 这是代码

  Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
  shareIntent.setType("image/*");
  shareIntent.putExtra(Intent.EXTRA_STREAM,   Uri.parse("file://" + mFilepath));
  shareIntent.putExtra(Intent.EXTRA_TEXT,"example");
  shareIntent.setPackage("com.facebook.katana");
  startActivity(shareIntent);

【参考方案1】：

Facebook 不允许预先填写消息。 详情请见this discussion。

【参考方案2】：

试试这个

// By this method we can post on facebook.
private void publishFeedDialog() 
     Session session = Session.getActiveSession();
     //if(session==null)
                           
            // try to restore from cache
            session = Session.openActiveSessionFromCache(dashBoard);
        
    Bundle params = new Bundle();
    params.putString("name", "MeetMeUp");
    params.putString("caption", "Discover events nearby, easily create events and invite your friends!");
    params.putString("description", "Finding, creating and sharing activities you’re passionate about are made easy with MeetMeUp. Whether you’re organizing a small gathering with friends, looking for a neighborhood football game or going to a local music concert, MeetMeUp makes it happen. ");
    params.putString("link", "https://play.google.com/store/apps/details?id=com.meetmeup.activity");
    params.putString("picture", "http://72.167.41.165/meetmeup/webservices/images/aaaaa-05.jpg");

    WebDialog feedDialog = (new WebDialog.FeedDialogBuilder(getActivity(),session, params)).setOnCompleteListener(
            new OnCompleteListener() 

                @Override
                public void onComplete(Bundle values, FacebookException error) 
                    if (error == null) 
                        // When the story is posted, echo the success
                        // and the post Id.
                        final String postId = values.getString("post_id");
                        if (postId != null) 
                            Toast.makeText(getActivity(), "Posted story, id: " + postId, Toast.LENGTH_SHORT).show();
                         else 
                            // User clicked the Cancel button
                            Toast.makeText(getActivity().getApplicationContext(), "Publish cancelled", Toast.LENGTH_SHORT).show();
                        
                     else if (error instanceof FacebookOperationCanceledException) 
                        // User clicked the "x" button
                        Toast.makeText(getActivity().getApplicationContext(), "Publish cancelled", Toast.LENGTH_SHORT).show();
                     else 
                        // Generic, ex: network error
                        Toast.makeText(getActivity().getApplicationContext(), "Error posting story", Toast.LENGTH_SHORT).show();
                    
                

            ).build();
    feedDialog.show();

【讨论】：

Shahid，请问我可以知道我必须为会话导入什么包吗？有 4 种不同的解决方案

哪一门课？能具体说明一下吗？

私人无效 publishFeedDialog() 会话会话 = Session.getActiveSession(); //if(session==null) // 尝试从缓存中恢复 session = Session.openActiveSessionFromCache(dashBoard);我找不到修复会话和仪表板的方法，它说我必须导入它们，但是这样做，我总是会出错

请用您的活动替换 dashBoard

做到了，但我总是遇到会话问题。是否打算作为 Facebook 会话？

【参考方案3】：

请检查下面的代码它可能对你有帮助。

Bundle parameters = new Bundle();
parameters.putString("message", category_item_name_desc.getText().toString());
parameters.putString("picture", categoryItemsModel.getImageUrl());
parameters.putString("caption", txtDescription_desc.getText().toString());
facebook.request("/me/feed", parameters, "POST");

【讨论】：

它很容易只发布图片
