Android Facebook API供稿对话框？

Question

Ok so I have setup a new Facebook app and I have the API and all that jazz setup also and have made successful posts to Facebook using the API. Here is my issue.

How do I format the text the way I want too??

For example:

description += "First line \r\n";
description += "Second line \r\n";

I am using the Facebook Android SDK and using the Feed Dialog approach as listed here

Also, I am using the feed dialog like so:

String description += "First line \r\n";
description += "Second line \r\n";
Facebook facebook = new Facebook("MY_APP_ID");
SetAccessToken(mContext, facebook);
params.putString("link", "");
params.putString("picture", "");
params.putString("name", "");
facebook.dialog(mContext, "feed", params, new Facebook.DialogListener() {

public void onFacebookError(FacebookError e) {

}

public void onError(DialogError e) {

}

public void onComplete(Bundle values) {

}

public void onCancel() {

}
});

Whenever, I do that it pulls up my Facebook dialog and the lines are not separated by line feeds. I also tried to use HTML such as

<p>Line 1</p>
<p>Line 2</p>

My guess is that I need to use another method in order to actually post formatted text, other than the feed dialog. I know that other Facebook apps are posting to users feeds with properly formatted text. Just not sure why the SDK doesn't offer the same functionality.

Just to add this, the submission is actually in a URL format at the end anyway. I tried adding URL escape characters but that didn't seem to do anything for me.

String url = endpoint + "?" + Util.encodeUrl(parameters);

Then they pass that into a webview. So I am currently looking into this. Any advice is appreciated.

as far as I have researched...facebook doesn't allow it's domain image to be posted on wall through post. So, we can't use it. Now what I am doing is getting the imge through following code:

ImageView user_picture;
        user_picture = (ImageView) findViewById(R.id.user_picture);
        URL img_value = null;
        Bitmap mIcon1 = null;
        try {
            img_value = new URL("http://graph.facebook.com/XXXX/picture");
            try {
                mIcon1 = BitmapFactory.decodeStream(img_value
                        .openConnection().getInputStream());
            } catch (IOException e) {
                // TODO Auto-generated catch block 
                e.printStackTrace();
            }
        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        if(mIcon1!=null){
            user_picture.setImageBitmap(mIcon1);
        }

if you want it to convert to byte array

 ByteArrayOutputStream baos = new ByteArrayOutputStream();   
        mIcon1.compress(Bitmap.CompressFormat.PNG, 100, baos);    
        b = baos.toByteArray(); 

Sending this image to my server and then posting to wall.

Have you tried:

String message = "<p>Line 1</p><p>Line 2</p>";
params.putString("message", Html.fromHtml(message).toString());
