Question

I would like to use HTTP post and get methods to retrieve images for a gallery view.
How would i go about doing this?

Do a search here for how to use HttpGet – there are lots of examples. But once you have a valid response you will need to use BitmapFactory.decodeStream to get a bitmap (something like the example code below) which you can draw into the ImageView.

HttpResponse response = HttpClient.execute(request);
HttpEntity entity     = response.getEntity();
StatusLine statusLine = response.getStatusLine();
int statusCode        = statusLine.getStatusCode();

if (statusCode == HttpStatus.SC_OK)
{
    InputStream inputStream = entity.getContent();
    Bitmap rawBitmap = null;

    BitmapFactory.Options bitmapOpt = new BitmapFactory.Options();
    bitmapOpt.inDither          = true;
    bitmapOpt.inPurgeable       = true;
    bitmapOpt.inInputShareable  = true;
    bitmapOpt.inTempStorage     = null;
    rawBitmap = BitmapFactory.decodeStream(inputStream, null, bitmapOpt);
}
