How do I view downloaded images through the URL in a Listview?

Question

The code I have so far is as follows::

import java.io.BufferedInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.URL;
import java.net.URLConnection;
import java.util.Currency;
import java.util.List;

import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.media.Image;
import android.net.Uri;
import android.os.Environment;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;

public class NoticiasAdapter extends ArrayAdapter {
    private final Activity activity;
    private final List stocks;
  //  private final Image img;


public NoticiasAdapter(Activity activity, List objects) {
    super(activity, R.layout.noticia_list_item , objects);
    this.activity = activity;
    this.stocks = objects;
   // this.img = url;
}


public View getView(int position, View convertView, ViewGroup parent) {
    View rowView = convertView;
    StockQuoteView sqView = null;

    if(rowView == null)
    {
        // Get a new instance of the row layout view
        LayoutInflater inflater = activity.getLayoutInflater();
        rowView = inflater.inflate(R.layout.noticia_list_item, null);

        // Hold the view objects in an object,
        // so they don't need to be re-fetched
        sqView = new StockQuoteView();
         //sqView.quote = (TextView) rowView.findViewById(R.id.ticker_symbol);
        sqView.ticker = (TextView) rowView.findViewById(R.id.ticker_price);
        sqView.img  = (ImageView) rowView.findViewById(R.id.img);     
        // Cache the view objects in the tag,
        // so they can be re-accessed later
        rowView.setTag(sqView);
    } else {
        sqView = (StockQuoteView) rowView.getTag();
    }

    // Transfer the stock data from the data object
    // to the view objects

    Noticias currentStock = (Noticias) stocks.get(position);
    String imagem3 = currentStock.getImagem();
    sqView.ticker.setText(currentStock.getTitulo());
    sqView.img.setImageURI(currentStock.getBitmapFromURL(imagem3));
  // sqView.quote.setText(currentStock.getDescricao());

    return rowView;
}

protected static class StockQuoteView {
    protected TextView ticker;
    protected TextView quote;
    protected ImageView img;
}

}

XML code:

<TextView
    android:id="@+id/ticker_price"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:gravity="center_vertical"
    android:text="Example application"
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:textSize="20sp" />



<ImageView 
  android:layout_width="fill_parent" 
  android:layout_height="wrap_content" 
  android:id="@+id/img" />
