    }

回答1:

You cannot specify a user message to the feed dialog. The "name", "caption", and "description" fields only apply to the "link" that's being shared.

This is by design.

The code for Publishing your Feed using the new Facebook SDK 3.0 is as follows:

// Method for publishing a feed to Facebook
private void publishStory() {
    Session session = Session.getActiveSession();

    Bundle postParams = new Bundle();
    postParams.putString("name", "Facebook SDK 3.0 Test By Arshad");
    postParams.putString("caption", "Build great social apps and get more installs.");
    postParams.putString("description",
                    "The Facebook SDK for Android makes it easier and faster to develop Facebook integrated Android apps.");
    postParams.putString("link", "https://developers.facebook.com/android");
    postParams.putString("picture",
                    "https://raw.github.com/fbsamples/ios-3.x-howtos/master/Images/iossdk_logo.png");

    Request.Callback callback = new Request.Callback() {
        public void onCompleted(Response response) {
            Log.i(TAG, "onCompleted FacebookRequest Done");
            JSONObject graphResponse = response.getGraphObject()
                    .getInnerJSONObject();
            try {
                graphResponse.getString("id");
            } catch (JSONException e) {
                Log.i(TAG, "JSON error " + e.getMessage());
            }
            FacebookRequestError error = response.getError();
            if (error != null) {
                Log.i(TAG, "FacebookRequestError" + error.getErrorMessage());
                Toast.makeText(getActivity().getApplicationContext(),
                        error.getErrorMessage(), Toast.LENGTH_SHORT).show();
            } else {
                Log.i(TAG, "FacebookRequest Done");
                Toast.makeText(getActivity().getApplicationContext(),
                        "Story Published to Your Wall", Toast.LENGTH_LONG).show();
            }
        }
    };

    Request request = new Request(session, "me/feed", postParams,
            HttpMethod.POST, callback);

    RequestAsyncTask task = new RequestAsyncTask(request);
    task.execute();
}

To post message from activity use this

    Bundle postParams = new Bundle(); 
    postParams.putString("message", "your message");
    postParams.putString("name", "Facebook SDK 3.0 Test By Arshad");
    postParams.putString("caption", "Build great social apps and get more installs.");
    postParams.putString("description",
                    "The Facebook SDK for Android makes it easier and faster to develop Facebook integrated Android apps.");
    postParams.putString("link", "https://developers.facebook.com/android");
    postParams.putString("picture",
                    "https://raw.github.com/fbsamples/ios-3.x-howtos/master/Images/iossdk_logo.png");
