galleria con horizontalscrollview

ciao
se può essere di aiuto :

ho fatto un'applicazione che visualizza una galleria orizzontale con il layout horizontalscollview, visto che la gallery è sconsigliata ,

ecco il source (non sono riuscito a sistemare bene le dimensioni delle foto , perchè non sono molto esperto , però funziona e magari può essere utile lo stesso) :

Codice:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >  

<HorizontalScrollView     
    android:id="@+id/hsvgn"  
    android:layout_marginTop="60dp"
    android:layout_marginBottom="60dp"
    android:layout_width="wrap_content" 
    android:layout_height="fill_parent">
    
    <LinearLayout
    android:id="@+id/gn"  
    android:orientation="horizontal"
    android:layout_marginLeft="4dp"
    android:layout_marginRight="4dp"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"/>
    
</HorizontalScrollView>

</FrameLayout>

Codice:

public class GalleryActivityN<MotionEvent> extends Activity {

	String image1; 
	String image2; 
	String image3; 
	String image4; 

	GalleryAdapter2 myAdapter;	
	ArrayList<String> ul    = new ArrayList<String>();
	ArrayList<Drawable> urlDrawable    = new ArrayList<Drawable>();
	String site = "....";
	
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.gallerian);

		Intent intent = getIntent();

		image1 =  intent.getStringExtra("image1");
		image2 =  intent.getStringExtra("image2");
		image3 =  intent.getStringExtra("image3");
		image4 =  intent.getStringExtra("image4");
		
		ul.add(site + image1);
		if (!image2.equals(""))
     		ul.add(site + image2);
		if (!image3.equals(""))
     		ul.add(site + image3);
		if (!image4.equals(""))
     		ul.add(site + image4);

		TaskGallery ts = new TaskGallery(GalleryActivityN.this, ul);
		ts.execute("");

    }
    
	private class TaskGallery extends AsyncTask<String, Integer, String> {
		private ProgressDialog dialog;
		private Activity activity;
		private Context context;
		ArrayList<String> ul1    = new ArrayList<String>();
		int i1 = 0;
		
		private Drawable d; 

		public TaskGallery(GalleryActivityN activity, ArrayList<String> ul) {
			this.activity = activity;
			context = activity;
			this.dialog = new ProgressDialog(context);
			ul1 = ul ; 
		}

		protected void onPreExecute() {
			this.dialog.setMessage("Loading...");
			this.dialog.show();
		}

		@Override
		protected String doInBackground(String... arg0) {			

			for (int i=0; i<ul1.size(); i++) {     
				
				try {
					String indirizzo = ul1.get(i);
					InputStream is = new URL(indirizzo).openStream(); // Carico l'immagine 
					d = Drawable.createFromStream(is, "src");
					urlDrawable.add(d);
					i1 = i1 + 1;
				} 
				catch (MalformedURLException e) {
					
					e.printStackTrace();
					} 
				catch (IOException e)           {
					e.printStackTrace();
					}

		    } 
			
			return null;
		}

		protected void onPostExecute(String result) {

			LinearLayout hsv = (LinearLayout) findViewById(R.id.gn);

			for (int i=0; i<i1; i++) {     
				Drawable d = urlDrawable.get(i);
    		    ImageView imageView = new ImageView(GalleryActivityN.this);
                imageView.setImageDrawable(d);
                imageView.setPadding(10,10,10, 10);
                imageView.setScaleType(ImageView.ScaleType.FIT_CENTER);
                hsv.addView(imageView);
			}
	
			 //setContentView(hsv);
			
			if (this.dialog.isShowing()) {
				this.dialog.dismiss();
			}

		}

	}    
	
}

ciao e... auguri
