Visualizzazione immagini in gallery

[Nokias]

Buongiorno a tutti , devo andare a visualizzare una serie di immagini in una gallery ed il codice che ho utilizzato è questo:

public class ViewImmaginiA exten<span class="forTooltip">ds</span> Activity {<br /> /** Called when the activity is first created. */<br /> @Override<br /> public void onCreate(Bundle icicle) {<br /> super.onCreate(icicle);<br /> setContentView(R.layout.immagini2);<br /> <br /> /* Find the gallery defined in the main.xml<br /> * Apply a new (custom) ImageAdapter to it. */<br /> ((Gallery) findViewById(R.id.gallery))<br /> .setAdapter(new ImageAdapter(this));<br /> }<br /> <br /> public class ImageAdapter extends BaseAdapter {<br /> /** The parent context */<br /> private Context myContext;<br /> <br /> /** URL-Strings to some rem<span class="forTooltip">ot</span>e images. */<br /> private String[] myRem<span class="forTooltip">ot</span>eImages = {<br /> //"/sdcard/Multimedia/Immagini/image_LARGE_2.unknown",<br /> "/sdcard/Multimedia/Immagini/image_LARGE_10.unknown",<br /> "/sdcard/Multimedia/Immagini/image_LARGE_11.unknown",<br /> "/sdcard/Multimedia/Immagini/image_LARGE_12.unknown",<br /> "/sdcard/Multimedia/Immagini/image_LARGE_13.unknown",<br /> "/sdcard/Multimedia/Immagini/image_LARGE_14.unknown",<br /> "/sdcard/Multimedia/Immagini/image_LARGE_15.unknown",<br /> };<br /> <br /> /** Simple Constructor saving the 'parent' context. */<br /> public ImageAdapter(Context c) { this.myContext = c; }<br /> <br /> /** Returns the amount of images we have defined. */<br /> public int getCount() { return this.myRemoteImages.length; }<br /> <br /> /* Use the array-Positions as unique IDs */<br /> public Object getItem(int position) { return position; }<br /> public long getItemId(int position) { return position; }<br /> <br /> /** Returns a new ImageView to<br /> * be displayed, depending on<br /> * the position passed. */<br /> public View getView(int position, View convertView, ViewGroup parent) {<br /> ImageView i = new ImageView(this.myContext);<br /> //ImageView jpgView = (ImageView)findViewById(R.id.jpgview);<br /> String myJpgPath;<br /> <br /> myJpgPath = myRemoteImages[position];<br /> //myJpgPath = "/sdcard/Multimedia/Immagini/image_LARGE_3.unknown";<br /> BitmapFactory.<span class="forTooltip">Op</span>tions options = new BitmapFactory.Options();<br /> options.inSampleSize = 2;<br /> Bitmap bm1 = BitmapFactory.decodeFile(myJpgPath, options);<br /> //jpgView.setImageBitmap(bm1); <br /> i.setImageBitmap(bm1);<br /> <br /> /* Image should be scaled as width/height are set. */<br /> i.setScaleType(ImageView.ScaleType.FIT_CENTER);<br /> /* Set the Width/Height of the ImageView. */<br /> i.setLayoutParams(new Gallery.LayoutParams(300, 250));<br /> return i;<br /> }<br /> <br /> /** Returns the size (0.0f to 1.0f) of the views<br /> * depending on the 'offset' to the center. */<br /> public float getScale(boolean focused, int offset) {<br /> /* Formula: 1 / (2 ^ offset) */<br /> return Math.max(0, 1.0f / (float)Math.pow(2, Math.abs(offset)));<br /> }<br /> }<br /> }<br /> <br />

55

                /* Image should be scaled as width/height are set. */

56

                i.setScaleType(ImageView.ScaleType.FIT_CENTER);

62

            /** Returns the size (0.0f to 1.0f) of the views

64

66

                return Math.max(0, 1.0f / (float)Math.pow(2, Math.abs(offset)));

68

        }

Ma il risultato è questo:



Mentre io pensavo di fare per ogni schermata un'immagine che faccio scorrere...così invece sembra che vengono sovrapposte.

Oppure una cosa del genere dite che sia adatta??



Grazie a tutti per le risposte!! ;-)
