是的，我看过其他问题，但那里的答案对我没有帮助。
我的应用程序从 Web 加载的图像放置在GridView. 这是和的getView代码onScrollStateChanged：
@Override
public void onScrollStateChanged(AbsListView absListView, int scrollState) {
switch(scrollState) {
case SCROLL_STATE_FLING :
case SCROLL_STATE_TOUCH_SCROLL :
downloader.stopAll();
adapter.removeExecutor(productCategoriesExecutor);
break;
case SCROLL_STATE_IDLE :
loadProductsChunk();
break;
}
}
@Override
public View getView(int i, View view, ViewGroup viewGroup) {
ProductView productView = (ProductView)view;
if(productView == null) {
productView = new ProductView(context, downloader);
productView.setLayoutParams(new GridView.LayoutParams(columnWidth, rowHeight));
}
JSONObject product = getItem(i);
if(product != null) {
try {
Log.i("ololo", String.format("thm: %d ", i) + product.getString("thumbnail"));
productView.setNewPrice(product.getInt("price"));
productView.setOldPrice(product.getInt("oldPrice"));
productView.showThumbnail(product.getString("thumbnail"));
} catch (JSONException e) {
e.printStackTrace();
}
}
else {
productView.setNewPrice(0);
productView.setOldPrice(0);
productView.showThumbnail(null);
}
return productView;
}
还有GridView：
<GridView
android:id="@+id/productsGrid"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:verticalSpacing="@dimen/products_list_grid_spacing"
android:horizontalSpacing="@dimen/products_list_grid_spacing"
android:stretchMode="columnWidth"
android:scrollingCache="false"
android:alwaysDrawnWithCache="false"
/>
如您所见，ProductView接收链接然后加载（或从缓存中获取）图像。刷新是在哪里执行，也不是在触摸，现在滚动都不是活动的。
public void displayRemoteImage(RemoteImage remoteImage) {
if(this.remoteImage != null) {
Log.i("ololo", this.remoteImage.getUrl() + remoteImage.getUrl());
}
if(this.remoteImage == null || !this.remoteImage.getUrl().equals(remoteImage.getUrl())) {
this.remoteImage = remoteImage;
this.remoteImage.setDelegate(this);
}
}
但是，如果我滚动到任何地方并返回（使用其他图片），它们会闪烁！
好吧，这不是什么大问题。
让我们再加载一行
搞什么鬼？？
而且-是的-如果我滚动到任何地方并返回，就会有需要的图片（并且没有重新加载）。
好吧，也许我们是失败者并且搞砸了我们的下载？让我们简单地刷新图片：
哈哈。你们太无聊了，我回家了。

更新
这在 HTC Explorer (2.3.3) 和 HTC Nexus One (2.3.6) 上发生，但在三星 Galaxy Tab 10.1 (3.2) 上没有发生。
