我正在使用UIL加载远程图像并填充FragmentStatePagerAdapter中的Fragments。 我已阅读自述文件和常见错误,但我无法解决这个错误。
这是配置:
ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(getApplicationContext())
.threadPoolSize(1)
.build();
ImageLoader.getInstance().init(config);
这是我显示图像的地方:
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
ImageLoader imgLoader = ImageLoader.getInstance();
DisplayImageOptions options = new DisplayImageOptions.Builder()
.showStubImage(R.drawable.loading)
.cacheOnDisc()
.resetViewBeforeLoading()
.bitmapConfig(Bitmap.Config.RGB_565)
.imageScaleType(ImageScaleType.IN_SAMPLE_INT)
.build();
imgLoader.displayImage(this.contentImage, this.imgView, options);
return layout;
}
这是我在适配器中销毁我的片段的地方:
public void destroyItem(ViewGroup container, int position, Object object) {
if (position >= getCount()) {
container.removeAllViews();
FragmentManager manager = ((Fragment) object).getFragmentManager();
FragmentTransaction trans = manager.beginTransaction();
trans.remove((Fragment) object);
trans.commit();
}
}
最后这是我得到的例外:

我对如何解决它一无所知。 加载的图像大小可变。它们可能在500KB到1.5MB之间变化。
答案 0 :(得分:12)
https://github.com/nostra13/Android-Universal-Image-Loader
从上面的链接
如果您经常使用通用图片加载器在您的应用中获得OutOfMemoryError
,请尝试下一步(所有这些或几个):
减少配置中的线程池大小(.threadPoolSize(...))。建议使用1 - 5.
在显示选项中使用.bitmapConfig(Bitmap.Config.RGB_565)
。 RGB_565
中的位图消耗的内存比ARGB_8888
少2倍。
在配置中使用.memoryCache(new WeakMemoryCache())
或在显示选项中禁用内存中的缓存(不要调用.cacheInMemory())。
在显示选项中使用.imageScaleType(ImageScaleType.IN_SAMPLE_INT)
。或者尝试.imageScaleType(ImageScaleType.EXACTLY)
。
避免使用RoundedBitmapDisplayer。它使用ARGB_8888配置创建新的Bitmap对象,以便在工作期间显示。
示例:修改以下链接中的c.ode,坚持以上几点以避免OOM
答案 1 :(得分:4)
<强>解决:强>
这不是UIL问题。问题出在页面适配器上。 GC中没有正确处理碎片中的位图,并且有一些间接引用保留它们。明确地释放位图解决了这个问题。
编辑:
这不是一个正确的UIL问题。我正在使用SupportFragment库,这可能没有适当调整。我的诀窍是手动释放屏幕上没有的每个位图,但应该以不同的方式查看问题。这个应用程序使用了大量的WebViews,在我看来是邪恶的,因为他们的内存消耗简直是愚蠢的!使用高分辨率图像添加UIL会使我的应用程序由于这些因素的组合而成为OOM。
这是一个经验性的解决方案,但确实有效。
答案 2 :(得分:2)
我对disk cache
进行了以下配置。我从来没有遇到过OOM的问题。
ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(
YourActivity.this).threadPoolSize(5)
.threadPriority(Thread.MIN_PRIORITY + 3)
.denyCacheImageMultipleSizesInMemory()
// .memoryCache(new UsingFreqLimitedMemoryCache(2000000)) // You
// can pass your own memory cache implementation
.memoryCacheSize(1048576 * 10)
// 1MB=1048576 *declare 20 or more size if images are more than
// 200
.discCache(new UnlimitedDiscCache(cacheDir))
// You can pass your own disc cache implementation
// .defaultDisplayImageOptions(DisplayImageOptions.createSimple())
.build();
创建cache dir
,
File cacheDir = new File(this.getCacheDir(), "imgcachedir");
if (!cacheDir.exists())
cacheDir.mkdir();
