我正在使用Volley从服务器上显示水平滑动视图中的图像,但我的图像相当大,这就是为什么我会遇到内存不足异常的原因。
以下是我的Volley类:
public class Volley{
private RequestQueue mRequestQueue;
private ImageLoader mImageLoader;
public Volley(Context ctx) {
Log.v("Volley", "Volley onCreate");
mRequestQueue = com.android.volley.toolbox.Volley.newRequestQueue(ctx);
final int maxMemory = (int) (Runtime.getRuntime().maxMemory() / 1024);
final int cacheSize = maxMemory / 8;
ImageLoader.ImageCache imageCache = new ImageLoader.ImageCache() {
LruCache<String, Bitmap> imageCache = new LruCache<String, Bitmap>(cacheSize);
@Override
public void putBitmap(String key, Bitmap value) {
imageCache.put(key, value);
}
@Override
public Bitmap getBitmap(String key) {
return imageCache.get(key);
}
};
mImageLoader = new ImageLoader(mRequestQueue, imageCache);
}
public void clear(Context ctx) {
mRequestQueue.cancelAll(ctx);
mImageLoader = null;
mRequestQueue = null;
}
public RequestQueue getRequestQueue() {
return mRequestQueue;
}
public ImageLoader getImageLoader() {
return mImageLoader;
}}
图片加载器代码:
image.setImageUrl(imagePhoto.url, getVolley(getContext()).getImageLoader());
public Volley getVolley(Context ctx) {
if(mVolley == null) {
mVolley = new Volley(getContext());
}
return mVolley;
}
异常:
