Ok, I've been trying to optimize my photo gallery for days now (this is my first Android project). All photos are loaded via Web page. I've started using Universal Image Loader, but I'm still not content with results. Here's my class: public class Galerija extends Activity { ArrayList<RSSItem> lista = new ArrayList<RSSItem>(); ArrayList<String> lst_slika = new ArrayList<String>(); RSSItem tempItem = new RSSItem(); ImageAdapter adapter; ImageLoader imageLoader; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity

ListView scrolling using UniversalImageDownloader not smooth

江枫思渺然 提交于 2019-12-03 08:34:31
I am using a ListView containing images. These images are loaded from the Internet inside the adapter. Therefore I am using the UniversalImageDownloader . Unfortunately the scrolling of the ListView "lags" for a short time as soon as I scroll down where new content has to be downloaded. I acutally expected behaviour like the ListView scrolls perfectly smooth, but the loading of the Image can of course take some more time - which should not effect the smoothness of scrolling. Furthermore, as I scroll back up the lags occur as well. It seems as if the images are not cached properly. Maybe my

View Pager with Universal Image Loader Out of Memory Error

问题 I am not really sure if a ViewPager with Universal Image Loader can/should be used as an alternate for a gallery like interface since I have run into an Out of Memory error while loading images from SD Card and viewing them in full screen mode. No matter what the number, it works all fine with a GridView but while viewing the images in the View Pager, each bitmap keeps eating up a lot of memory and after 10 or so images, it gives the out of memory error. I have seen almost all the questions

Check if Image is in Cache - Universal Image Loader

老子叫甜甜 提交于 2019-12-03 05:44:06
I guess the title says it all. I tried: imageLoader.getMemoryCache().get(key); with the image uri as key, but it always return null although I enabled caching in the config. Use MemoryCacheUtils . MemoryCacheUtils.findCachedBitmapsForImageUri(imageUri, ImageLoader.getInstance().getMemoryCache()); Memory cache can contain several bitmaps (diffenrent sizes) for one image. So memory cache use special keys, not image urls. It should be MemoryCacheUtil s , so you should use MemoryCacheUtils.findCachedBitmapsForImageUri(imageUri, ImageLoader.getInstance().getMemoryCache()); For disk cache use below
