android - imageview 上显示的图像崩溃应用程序

Question

我使用 glide 显示来自 url 的图像。当我使用调试器时，url 包含图像。但问题是应用程序运行时它会关闭。在 imageview 的代码中有什么可做的吗？请帮我解决这个问题.如果我问错了，请原谅我。提前致谢。我的代码在下面提供。

    public class ProductImages extends AsyncTask<Void , Void, Void> {
        int status;StringBuilder sb;
        String strJson, postData;
        JSONArray jsonArray;

        boolean pass=false;
        ArrayList<String> imgurls=new ArrayList<>();

            super.onPreExecute();

        }

Glide 不需要在 中声明 GlideModule AndroidMinifest.xml。您只需要执行以下步骤：

1. YourGlideModule 扩展了 AppGlideModule，您可以覆盖 YourGlideModule 类中的函数 applyOptions。

2. 您应该在android studio -> build -> make project中制作项目，它将生成 GlideApp 类。

3. 使用 GlideApp 如

   GlideApp.with(this)
           .load(imagegUrl)
           .into(imageview)
