Android:如何使用Facebook上的图片发布消息？

Question

在我的应用程序中,我使用此代码在Facebook上发布照片.

码:

 // For Facebook ===================================
            Button facebookButton = (Button) saveButtonDialog.findViewById(R.id.facebook);
            facebookButton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    saveButtonDialog.dismiss();

                    saveImageFunction(); // to save the Image

                    facebook.authorize(TWSBIDrawMainActivity.this, new String[]{ "user_photos,publish_checkins,publish_actions,publish_stream"},new DialogListener() {                     
                        @Override                     
                        public void onComplete(Bundle values) {   
                            postImageonWall(); 
                            Toast.makeText(getApplicationContext(), "Image Posted on Facebook.", Toast.LENGTH_SHORT).show();

                        }                      
                        @Override                     
                        public void onFacebookError(FacebookError error) {                     
                        }                      
                        @Override                     
                        public void onError(DialogError e) {                     
                        }                      
                        @Override                     
                        public void onCancel() {                     
                        }                 
                    }); 
                }
            });



 public void postImageonWall() {             
    byte[] data = null;               

    Bitmap bi = BitmapFactory.decodeFile(APP_FILE_PATH + "/"+filename+".jpg");
    //Bitmap bi = BitmapFactory.decodeResource(getResources(), R.drawable.icon);             
    ByteArrayOutputStream baos = new ByteArrayOutputStream();              
    bi.compress(Bitmap.CompressFormat.JPEG, 100, baos);              
    data = baos.toByteArray();                
    Bundle params = new Bundle();              
    params.putString(Facebook.TOKEN, facebook.getAccessToken());              
    params.putString("method", "photos.upload");              
    params.putByteArray("picture", data);               
    AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);              
    mAsyncRunner.request(null, params, "POST", new SampleUploadListener(), null);    

现在我可以使用此代码发布照片.但现在我想用这张照片发布消息.那我还有什么需要做的？

请帮我解决这个问题.谢谢.

只需要为Bunlde对象参数添加一个额外的参数.这是扫管笏我做的,

Bundle params = new Bundle();              
params.putString(Facebook.TOKEN, facebook.getAccessToken());              
params.putString("method", "photos.upload");              
params.putByteArray("picture", data);     

params.putString("caption",facebook_comment);

AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);              
mAsyncRunner.request(null, params, "POST", new SampleUploadListener(), null);

我想你错过了这一行.
