Question

当我想显示左侧菜单时出现此异常。有人知道如何解决这个问题吗？

这是我要显示的代码

public static void displayRoundImage(ImageView view, String path, ImageLoadingListener listener) {
    ImageLoader loader = ImageLoader.getInstance();
    try {
        loader.displayImage(path, view, ROUND_DISPLAY_IMAGE_OPTIONS, listener);
    } catch (OutOfMemoryError e) {
        e.printStackTrace();
        loader.clearMemoryCache();
    }
}

这是调用方法的代码

private View prepareHeaderView(int layoutRes, String url, String email) {
    View headerView = getLayoutInflater().inflate(layoutRes, mDrawerList,
            false);
    ImageView iv = (ImageView) headerView.findViewById(R.id.image);
    TextView tv = (TextView) headerView.findViewById(R.id.email);

    ImageUtil.displayRoundImage(iv, url, null);
    tv.setText(email);

    return headerView;
}

实际上我不知道为什么会出现此错误。我试图初始化它，但我失败了。谁能帮帮我？

Answer 1

抱歉，伙计们，我通过将其添加到我的 onCreate 方法中解决了我的问题

ImageLoader.getInstance().init(ImageLoaderConfiguration.createDefault(this));

但是，谢谢大家的帮助。

Answer 2

嗨，请像这样在 onCreate() 中初始化 ImageLoader 配置... 在class

之外声明

private ImageLoader imageLoader = ImageLoader.getInstance();
private DisplayImageOptions options;

然后在onCreate()

里面

imageLoader.init(ImageLoaderConfiguration.createDefault(getBaseContext()));
    options = new DisplayImageOptions.Builder().showImageForEmptyUri(R.drawable.image_not_avbl).showImageOnFail(R.drawable.image_not_avbl)
            // HERE
            .bitmapConfig(Bitmap.Config.RGB_565).cacheOnDisc(true).delayBeforeLoading(0).cacheInMemory(true).resetViewBeforeLoading(false)
            .imageScaleType(ImageScaleType.IN_SAMPLE_POWER_OF_2).build();

快乐编码:-)
