android - Universal Image Loader UIL nostra 内存不足错误

Question

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

配置如下:

ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(getApplicationContext())
    .threadPoolSize(1)
    .build();
    ImageLoader.getInstance().init(config);

这里是我展示图片的地方:

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 fragment 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();
    }
}

最后这里是我得到的异常:

}

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。

如果您经常在使用 Universal Image Loader 的应用中遇到 OutOfMemoryError，请尝试下一步(全部或多个):

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

2. 在显示选项中使用 .bitmapConfig(Bitmap.Config.RGB_565)。 RGB_565 位图占用的内存比 ARGB_8888 少 2 倍。

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

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

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

示例:修改下面链接中的c.ode，坚持以上几点，避免OOM
