Question

How can I turn the static image

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="0.67"
        android:src="@drawable/static_image" />

into an ImageView whose source can be dynamically set to data that is not already in the res folder?

That is, my application has an icon on the screen but the actual image for the icon is downloaded from an outside server and can change dynamically. How do I update the ImageView with the desired image upon download? I want something functionally like:

Image selectedImage = //get from server

myImageView.setImage(selectedImage);

Ur question is not clear. If u just wanna have an image(that is in some url) set to an image view,

Bitmap bmp=getBitmapFromURL(ur url here);
imgview.setImageBitmap(bmp);

and write this function:

public static Bitmap getBitmapFromURL(String src) {  
        try {

            URL url = new URL(src);
            HttpURLConnection connection = (HttpURLConnection) url
                    .openConnection();
            connection.setDoInput(true);
            connection.connect();
            InputStream input = connection.getInputStream();
            Bitmap mybitmap = BitmapFactory.decodeStream(input);

            return mybitmap;

        } catch (Exception ex) {

            return null;
        }
