在我的Android应用程序中,我使用Volley在自定义列表视图中加载图像。排空的磁盘缓存内存不足问题

当我刷新(删除所有项目,并负载TIEMS)的ListView很多次, 我的应用程序被杀害,此消息

如何解决呢?

这个问题差不多2年了,但我仍在寻找解决方案。 [这个问题](https://stackoverflow.com/questions/24095909/volley-out-of-memory-error-weird-allocation-attempt/24422376#comment54546831_24422376)是相似的,但答案不适合我。 OP你有没有想过? – yuval

你从

https://stackoverflow.com/a/21299261/3399432

试图

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

这改变了高速缓存大小

我是有加载图像非常相似的问题变成一个ListView。看来你必须自己处理从缓存中拉出来。

下面是我的实现,我有我的public View getView(int position, View convertView, ViewGroup parent)适配器方法:

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); 
}
