Passing ArrayList<Bitmap> into another class and convert to Bitmap[]
<p>I fetch the image URL from my PHP and MySQL database. Everything here is fine, because the <code>Log.d</code> shows the result with a valid image URL.</p>

<pre><code>if (success == 1) {
    JSONArray comments = json.getJSONArray("photos");
    for (int i = 0; i &lt; comments.length(); i++) {
        JSONObject m = comments.getJSONObject(i);
        final String filename = m.getString("filename");
        final String extension = m.getString("extension");
        String upload_at = m.getString("upload_at");
        String uid = m.getString("uid");

        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                Bitmap mThumbIds = fetchImage(filepath_min
                + filename + "." + extension);
        Log.d("Photo URL", filepath_min + filename + "." + extension);
                List&lt;Bitmap&gt; l = Arrays.asList(mThumbIds);
                photoList = new ArrayList&lt;Bitmap&gt;(l);
            }
        });
    }
}

// Instance of ImageAdapter Class
mHandler.postDelayed((new Runnable() {
    public void run() {
        imgGrid.setAdapter(new ImageAdapter(
        PhotoViewerActivity.this, photoList));
    }
}), 1000);

<p>Below this for fetch an image from the given URL and return as Bitmap.
Nothing problem here, just for reference want to show that the return is Bitmap.</p>

<pre><code>public Bitmap fetchImage(String urlstr) {
    try {
        URL url;
        url = new URL(urlstr);

        HttpURLConnection c = (HttpURLConnection) url.openConnection();
        c.setDoInput(true);
        c.connect();
        InputStream is = c.getInputStream();
        Bitmap img;
        img = BitmapFactory.decodeStream(is);
        return img;
        } catch (MalformedURLException e) {
        Log.d("RemoteImageHandler", "fetchImage passed invalid URL: "
        + urlstr);
        } catch (IOException e) {
        Log.d("RemoteImageHandler", "fetchImage IO exception: " + e);
    }
    return null;
}
</code></pre>

<p>This is my ImageAdapter for viewing image in GridView.</p>

<pre><code>public class ImageAdapter extends BaseAdapter {
    private Context mContext;
    List&lt;Bitmap&gt; list = new ArrayList&lt;Bitmap&gt; l;

    public ImageAdapter(Context c, ArrayList&lt;Bitmap&gt; l) {
        mContext = c;
        list = l;
    }

    public Bitmap[] mThumbIds = list.toArray(new Bitmap[list.size()]);

    @Override
    public int getCount() {
        return mThumbIds.length;
    }

    @Override
    public Object getItem(int position) {
        return mThumbIds[position];
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ImageView imageView = new ImageView(mContext);
        imageView.setImageBitmap(mThumbIds[position]);
        imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
        imageView.setLayoutParams(new GridView.LayoutParams(130, 130));
        return imageView;
    }

}
</code></pre>

<p>Here is my problem. None image shown on the activity.
When I try hardcoded URL with fetch array in Bitmap[] mThumbIds, its was success.</p>

<pre><code>Bitmap[] mThumbIds = { fetchImage("http://...jpg"),
                       fetchImage("http://...jpg") }
</code></pre>

<p>I don't know what's wrong. I've tried <code>Bitmap[] mThumbIds = list.toArray(new Bitmap[list.size()]);</code> to convert ArrayList to Array.
