Android GridView从下往上加载图像问题

我正在使用GridView以异步方式显示图像并加载此图像。一切正常，只有问题是图像从下到上加载到GridView中，而不是从上到下。真的无法理解如何解决这个问题。请帮我解决这个问题。Android GridView从下往上加载图像问题

EDIT1： GridView的适配器代码：

public class ImageThumbAdapter extends BaseAdapter { 

     private Activity context; 
     private ArrayList<HashMap<String, String>> mImageList; 
     private ImageLoader mImageLoader; 
     private int mItemHeight = 0; 
     private int mNumColumns = 0; 
     private GridView.LayoutParams mImageViewLayoutParams; 

     public ImageThumbAdapter(Activity c, 
       ArrayList<HashMap<String, String>> imageList) { 
      context = c; 
      mImageList = imageList; 
      mImageLoader = new ImageLoader(context); 
      mImageViewLayoutParams = new GridView.LayoutParams(
        LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT); 
     } 

     public int getCount() { 
      return mImageList.size(); 
     } 

     public Object getItem(int position) { 
      return mImageList.get(position); 
     } 

     public long getItemId(int position) { 
      return position; 
     } 

     public void addImage(HashMap<String, String> image) { 
      mImageList.add(image); 
     } 

     public View getView(int position, View convertView, ViewGroup parent) { 


      // Now handle the main ImageView thumbnails 
      ImageView imageView; 

      if (convertView == null) { // if it's not recycled, instantiate and 
             // initialize 
       imageView = new ImageView(context); 
       imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); 
       imageView.setLayoutParams(mImageViewLayoutParams); 
      } 
      else { // Otherwise re-use the converted view 
       imageView = (ImageView) convertView; 
      } 

      if (imageView.getLayoutParams().height != mItemHeight) { 
       imageView.setLayoutParams(mImageViewLayoutParams); 
      } 

      String imageName = String.format(
        "gallery_", 
        mImageList.get(position).get(TAG_THUMB_URL)); 

      imageView.setTag(imageName); 
      mImageLoader.setDefualtStub(R.drawable.ic_thumbnail); 

      mImageLoader.DisplayImage(
        mImageList.get(position).get(TAG_THUMB_URL), context, 
        imageView, imageName, new ImageLoadingListener()); 

      return imageView; 
     } 

     .... 

    }

EDIT2：日志用于位置

你介意张贴代码？ – 2012-08-09 18:34:50

@javaMe nope。增加适配器代码。 – amsiddh 2012-08-09 18:50:24

你可以添加一个像Log.d（“ImageThumbAdapter”，“Loading image：”+ position）'的日志'然后共享日志输出吗？也许无论出于什么原因，getView方法都会首先在较低的位置被调用。 – mercutio 2012-08-09 19:47:19

我有同样的问题，直到我发现的stackFromBottom属性gridview。

在你的GridView的XML，放：

android:stackFromBottom="false"
