Android Volley给我一个outOfMemory异常

前端之家收集整理的这篇文章主要介绍了Android Volley给我一个outOfMemory异常前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我正在使用凌空从服务器的水平滑动视图中显示图像,但我的图像是相当大的,这是我得到一个例外的内存

下面是我的凌空课:

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;
}}

图像加载器代码

image.setImageUrl(imagePhoto.url,getVolley(getContext()).getImageLoader());

public Volley getVolley(Context ctx) {
    if(mVolley == null) {
        mVolley = new Volley(getContext());
    }
    return mVolley;
}

例外:

解决方法

我确实解决了这个问题,为LruCache的BitmapLruCache提供了适当的缓存
public class BitmapLruCache extends LruCache<String,Bitmap> implements ImageLoader.ImageCache {
public static int getDefaultLruCacheSize() {
    final int maxMemory = (int) (Runtime.getRuntime().maxMemory() / 1024);
    final int cacheSize = maxMemory / 8;

    return cacheSize;
}

public BitmapLruCache() {
    this(getDefaultLruCacheSize());
}

public BitmapLruCache(int sizeInKiloBytes) {
    super(sizeInKiloBytes);
}

@Override
protected int sizeOf(String key,Bitmap value) {
    return value.getRowBytes() * value.getHeight() / 1024;
}

@Override
public Bitmap getBitmap(String url) {
    return get(url);
}

@Override
public void putBitmap(String url,Bitmap bitmap) {
    put(url,bitmap);
}

}
