我试图获取Arraylist（这里是albumArrayList）的图像来设置ImageSwitcher中的视图。但是无法获取图像。请帮我解决这个问题。谢谢..
public class ImageViewActivity extends Activity{
public static Gallery iGllry;

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);

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();
}

imageView.setTag(album_photo1.getUrl());
imageLoader.DisplayImage(album_photo1.getUrl(),false,imageView);
imageView.setScaleType(ImageView.ScaleType.FIT_XY);
return imageView;
}
}
