Update ImageSwither to pull from URL?

I am trying to update the ImageSwither app to pull its images from a URL. I am able to update the thumbnails since it is using an

ImageView

where I can call

setImageBitmap(bitmap)
Parsed in 0.029 seconds,  using GeSHi 1.0.8.4

, but I want those images to be displayed larger when selected.

Here is some updated code I tried but it doesn't work.

public void onItemSelected(AdapterView parent, View v, int position, long id) {
 
        //mSwitcher.setImageResource(mImageURLIds[position]);
 
        mSwitcher.setImageURI(ContentURI.create(mImageURLIds[position]));
 
    }
Parsed in 0.033 seconds,  using GeSHi 1.0.8.4

I also tried the code (similar to what was used in the weatherforecast) in the

onItemSelected

method, but I'm not sure how to tell the gallery to use that image.

Sorry if this doesn't make sense, but I just started using Android and am in learning mode right now.

Thanks!

Hello ryank,

what type and content is your mImageURLIds-Array :?:

The code from the WeatherForecast worked pretty well, you could do sth like this (code without syntax-errors, but not live tested):

                ImageSwitcher is = new ImageSwitcher(this); // or findViewbyId, whatever you have in your code...
 
                try {
                        URL aURL = new URL("http://www.anddev.org/favicon.ico");
 
                        URLConnection conn = aURL.openConnection();
                        conn.connect();
                        InputStream in = conn.getInputStream();
                        BufferedInputStream bis = new BufferedInputStream(in);
                        Bitmap bm = BitmapFactory.decodeStream(bis);
                        bis.close();
                        in.close();
                        BitmapDrawable bmd = new BitmapDrawable(bm);
                        is.setImageDrawable(bmd);
                } catch (Exception e) {
                        Log.e("DEBUGTAG", "Error",e);
                }

Thanks plusminus! I will try when I get home.

Was I on the right track as far as putting that code in the onItemSelected() method?

Thanks again, and I will let you know how it goes!
