我在 android studio 中使用 Glide 进行图像显示，但如何将 Glide 实现到我的列表视图？

Question

我需要任何人的帮助..请尊重我的问题..

好的，我的问题是我想为我的列表视图使用 Glide，但我不知道该怎么做..

请构造我的 listviewadapter 以便 Glide 可以工作，给我任何其他可能的解决方案来实现我的目标..

我的目标是我只想使用 Glide 和 JSON 在列表视图或网格视图中显示图像和文本，JSON 结果来自我的 php 脚本..

这是我的代码..

Answer 1

只需使用：Glide.with(context) .load(resultp.get(CategoryFragment.products_image)) .into(products_image);

代替

imageLoader.DisplayImage(resultp.get(CategoryFragment.products_image), products_image);

在你的 ListViewAdapter.java
