I want to zoom the image but I am not able to get, I am getting image url link in i.getStringExtra("image");....what should I do ?

1.)SingleItemView.java

      public class SingleItemView extends Activity {      ImageLoader imageLoader = AppController.getInstance().getImageLoader();      private static String TAG;      ImageView_Main itemImage;        @Override      protected void onCreate(Bundle savedInstanceState) {          super.onCreate(savedInstanceState);          // Get the view from singlelistview.xml          setContentView(R.layout.singlelistview);            try {              Intent i = getIntent();              String image = i.getStringExtra("image");                // Zoom the image              NetworkImageView itemImage = (NetworkImageView) findViewById(R.id.itemImage);              itemImage.setImageUrl(image, imageLoader);          } catch (Exception e) {              Log.i(TAG, e.getMessage());          }      }  }    

2.)singlelistview.xml
