Question

我有GridView的自定义适配器，我在其中显示来自服务器的数据，我成功显示数据但是当我滚动gridview多次时它给我错误java.lang.OutOfMemoryError我的logcat错误如下：

用于显示图像我正在使用通用图像加载器

ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(context)
    .build();
    ImageLoader.getInstance().init(config);  


DisplayImageOptions options = new DisplayImageOptions.Builder()
    .showImageOnLoading(R.drawable.ic_stub)
    .showImageForEmptyUri(R.drawable.ic_stub)
    .showImageOnFail(R.drawable.ic_stub)
    .resetViewBeforeLoading(false)
    .delayBeforeLoading(1000)
    .cacheInMemory(true)
    .cacheOnDisc(true)
    .considerExifParams(false)
    .imageScaleType(ImageScaleType.IN_SAMPLE_POWER_OF_2)
    .bitmapConfig(Bitmap.Config.RGB_565)
    .imageScaleType(ImageScaleType.EXACTLY)
    .displayer(new SimpleBitmapDisplayer())


    .handler(new Handler())
    .build();  

ImageLoader.getInstance().displayImage(image_url_string,
            image_coupon, options);

请帮我解决这个错误。谢谢。

Answer 1

在这里，我建议您在创建newinstance之前删除旧实例，因为每次创建newinstance并且之前的内存不会被旧实例释放，因此当您的设备内存在某些尝试后变低时。它会让你失去内存错误。所以只需清除以前的实例和记忆。

Answer 2
