我正在使用 UIL 加载远程图像并填充 FragmentStatePagerAdapter 中的片段。我已阅读自述文件和常见错误,但我无法解决此错误。

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:

}

我不知道如何解决它。加载的图像大小可变。它们可能从 500KB 到 1.5MB 不等。

从上面的链接

如果您经常OutOfMemoryError使用 Universal Image Loader 进入您的应用程序,那么请尝试下一个(全部或多个):

  1. 减少配置中的线程池大小 (.threadPoolSize(...))。建议使用 1 - 5。

  2. .bitmapConfig(Bitmap.Config.RGB_565)在显示选项中使用。中的位图RGB_565消耗的内存是 中的 2 倍ARGB_8888

  3. 在配置中使用.memoryCache(new WeakMemoryCache())或在显示选项中完全禁用内存中的缓存(不要调用 .cacheInMemory())。

  4. .imageScaleType(ImageScaleType.IN_SAMPLE_INT)在显示选项中使用。或者试试.imageScaleType(ImageScaleType.EXACTLY)

  5. 避免使用 RoundedBitmapDisplayer。它使用 ARGB_8888 配置创建新的位图对象,以便在工作期间显示。

示例:修改以下链接中的代码坚持以上几点以避免OOM

缓存图像并显示

解决了:

这不是 UIL 问题。问题出在页面适配器上。GC 没有正确处理片段中的位图,并且有一些间接引用保留了它们。释放位图明确地解决了这个问题。

编辑:

这不是一个适当的 UIL 问题。我正在使用 SupportFragment 库,这可能没有正确调整。对我来说,诀窍是手动释放不在屏幕上的每个位图,但应该以不同的方式看待问题。这个应用程序使用了大量的 WebView,在我看来是邪恶的,因为它们的内存消耗简直是愚蠢的!由于这些因素的结合,添加带有高分辨率图像的 UIL 会使我的应用程序运行 OOM。

这是一个有点经验的解决方案,但它确实有效。

我有以下配置disk cache。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();

要创建cache dir

File cacheDir = new File(this.getCacheDir(), "imgcachedir");
    if (!cacheDir.exists())
        cacheDir.mkdir();
