How to display images from web in gallery view in android

I displayed images to the gallery view with images in drawable folder. MyCode

public class GalleryView extends Activity {
Integer[] pics = {
  R.drawable.antartica1,
  R.drawable.antartica2,
  R.drawable.antartica3,
  R.drawable.antartica4,
  R.drawable.antartica5,
  R.drawable.antartica6,
  R.drawable.antartica7,
  R.drawable.antartica8,
  R.drawable.antartica9,
  R.drawable.antartica10
};
ImageView imageView;

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Gallery ga = (Gallery)findViewById(R.id.Gallery01);
    ga.setAdapter(new ImageAdapter(this));

    imageView = (ImageView)findViewById(R.id.ImageView01);
    ga.setOnItemClickListener(new OnItemClickListener() {



public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
 long arg3) {
Toast.makeText(getBaseContext(), 
  "You have selected picture " + (arg2+1) + " of Antartica", 
  Toast.LENGTH_SHORT).show();
imageView.setImageResource(pics[arg2]);

}

    });

}



}

But I have images in an arraylist like this

How to show these images in gallery view. Can anyone help me to do this?

Solution

you should download images and then display them with Gallery.
i recommend you to use UIL
