如何獲取ImagesReader視圖上的ArrayList

Question

我想獲取Arraylist（這裏albumArrayList）的圖像來設置ImageSwitcher.But中的視圖，但無法獲取圖像。請幫我解決這個問題..謝謝。 。

public class ImageViewActivity extends Activity{ 

    public static Gallery iGllry; 
    public static ImageSwitcher imageSwitcher; 
    public static ImageLoader imageLoader; 

    public static ArrayList<AddAlbumDetailBean> album_photos1; 
    public static AddAlbumDetailBean album_photo1; 

    public static ArrayList<Integer> albumArrayList; 
    public static Integer albumarrayob; 

    public static ArrayList<Integer> albumArrayList2; 
    public static Integer albumarrayob2; 

    public static ArrayList<Bitmap> ablum_photosbit; 
    public static Bitmap albmphtbit; 


    public static ImageView imgvwfrgallery; 
    public static GridActivity gridActivity; 
    //public static int position = gridActivity.posi; 

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

    iGllry = (Gallery) findViewById(R.id.img_glry); 

    album_photos1 = GridActivity.albumPhotos; 
    int count1 = album_photos1.size(); 
    Log.i("array of images", ""+ count1); 
    albumArrayList= new ArrayList<Integer>(); 
    for(int i=0;i<album_photos1.size();i++){ 
     albumArrayList.add(albumarrayob); 
    } 
    int count = albumArrayList.size(); 
    Log.i("Array of images in integer array",""+count); 
    imgvwfrgallery= (ImageView)findViewById(R.id.imgvwfrgllry); 
    iGllry.setAdapter(new EfficientAdapter1(this)); 
    iGllry.setOnItemClickListener(new OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> parent, View v, int position,long id) { 
      // TODO Auto-generated method stub 
      Log.e("Enters in click event of gallery","GALLERY"); 
      imgvwfrgallery.setImageResource(albumArrayList.indexOf(album_photo1)); 
     Toast.makeText(getApplicationContext(), "Position "+(position+1), Toast.LENGTH_SHORT).show(); 
     } 
    }); 
} 

public class EfficientAdapter1 extends BaseAdapter{ 
    private Context mContext1; 
    private LayoutInflater mInflater1; 
    ImageLoader imageLoader; 
    int count; 

    public EfficientAdapter1(ImageViewActivity imageViewActivity) { 
     // TODO Auto-generated constructor stub 
     mInflater1 = LayoutInflater.from(imageViewActivity); 
     mContext1 = imageViewActivity; 
     imageLoader = new ImageLoader(mContext1); 
    } 
    @Override 
    public int getCount() { 
     // TODO Auto-generated method stub 
     Log.e("no. of photos in arraylist COUNT", ""+album_photos1.size()); 
     return album_photos1.size(); 
    } 
    @Override 
    public Object getItem(int position) { 
     // TODO Auto-generated method stub 
     return position; 
     //return 0; 
    } 
    @Override 
    public long getItemId(int position) { 
     // TODO Auto-generated method stub 
     return position; 
     //return 0; 
    } 
    @Override 
    public View getView(int position, View convertView1, ViewGroup parent) { 
     // TODO Auto-generated method stub 
     ImageView imageView = new ImageView(mContext1); 
     album_photo1 = album_photos1.get(position); 
     Log.i("album photos get view ", ""+album_photo1); 
     Log.i("Position in getview ", ""+position); 
     imageView.setTag(album_photo1.getUrl()); 
     imageLoader.DisplayImage(album_photo1.getUrl(),false,imageView); 
     imageView.setScaleType(ImageView.ScaleType.FIT_XY); 
     return imageView; 
     } 
}
