Question

我正在使用this tutorial来了解如何通过Android应用连接到Facebook。我特别感兴趣的是他展示如何在墙上发布内容/用户状态的部分。

该教程相当简单，但我的要求是我需要让应用程序附加用户发布的内容。

如何实现？

Answer 1

您可以这样做：

private void publishToFacebook(String message)
      {
            long songId = MusicUtils.getCurrentAudioId();
                long albumId = MusicUtils.getCurrentAlbumId();
            String albumartUrl = MusicUtils.getArtworkUrlFromExtrasCache(getApplicationContext(),albumId);
            Bitmap bm = MusicUtils.getArtworkFromExtrasCache(getApplicationContext(),albumId,false,false);
            if(bm == null)
            bm = MusicUtils.getDefaultArtwork(getApplicationContext());

                shareFacebookConnector = new ShareConnector(MediaPlaybackActivity.this, getApplicationContext());
            shareFacebookConnector.setCurrentAlbum(MusicUtils.getCurrentAlbumName());
            shareFacebookConnector.setCurrentArtist(MusicUtils.getCurrentArtistName());
            shareFacebookConnector.setCurrentTrack(MusicUtils.getCurrentTrackName());
        shareFacebookConnector.setCurrentCoverArt(bm);
        if(albumartUrl != null)
        {
        shareFacebookConnector.setCurrentCoverUrl(albumartUrl);
        }

        LayoutInflater inflater = this.getLayoutInflater();
        final View dialoglayout = inflater.inflate(R.layout.facebook_share, (ViewGroup) findViewById(R.id.facebook_share_root));
        final ImageView image = (ImageView) dialoglayout.findViewById(R.id.facebook_cover_view);
        input = (EditText) dialoglayout.findViewById(R.id.facebook_share_content);
        ContextThemeWrapper ctw = new ContextThemeWrapper(this, R.style.AlertDialogCustom);
        AlertDialog.Builder alert = new AlertDialog.Builder(ctw);   
        if(message != null)
        {
                shareFacebookConnector.publishToFacebook(alert, input, message);    
        }
        else
        {
        shareFacebookConnector.publishToFacebook(alert, input, null);  
        }
        alert.setView(dialoglayout);
        alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {  
            bAlertInProgress = false; 
            String messageToPost = input.getText().toString();
            shareFacebookConnector.postMessageToWall(messageToPost, false);         
        } 
    });
    alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {

        public void onClick(DialogInterface dialog, int whichButton) {
            bAlertInProgress = false;
            Toast.makeText(MediaPlaybackActivity.this, "Wall post cancelled !", Toast.LENGTH_SHORT).show();
            //finish();    

        }
    });
    bAlertInProgress = true;
    mShareKey = "********";
    alertDialog = alert.create();
    alertDialog.show();
}

您必须以session.openForPublish();打开会话，并且您需要权限“publish_action”
