在我的Android应用中,我使用Volley在自定义列表视图中加载图片。
当我多次刷新(删除所有项目并加载tiems)listview时, 我的应用程序被此消息杀死
我该如何解决?

你试过吗
RequestQueue volleyQueue = Volley.newRequestQueue(this);
DiskBasedCache cache = new DiskBasedCache(getCacheDir(), 16 * 1024 * 1024);
volleyQueue = new RequestQueue(cache, new BasicNetwork(new HurlStack()));
volleyQueue.start();

这会更改缓存大小

我在将图像加载到ListView时遇到了类似的问题。看来你必须自己处理缓存。
以下是我在public View getView(int position, View convertView, ViewGroup parent)
适配器方法中的实现:
Bitmap cachedBitmap = imageCache.getBitmap(item.getPhotoUrl());
if (cachedBitmap != null)
{
holder.photo.setImageBitmap(cachedBitmap);
}
else {
ImageLoader imageLoader = new ImageLoader(Volley.newRequestQueue(this.context), imageCache);
imageLoader.get(item.getPhotoUrl(), new ImageLoader.ImageListener() {
@Override
public void onResponse(ImageLoader.ImageContainer response, boolean isImmediate) {
if (item.getPhotoUrl() != null && response.getBitmap() != null)
imageCache.putBitmap(item.getPhotoUrl(), response.getBitmap());
}
@Override
public void onErrorResponse(VolleyError error) {
error.printStackTrace();
}
});
//This is a custom imageview, you can create your own implementation for loading the image url to the imageview
holder.photo.setImageUrl(item.getPhotoUrl(), imageLoader);
}
