我在ListvIEw项目中使用vIEw pager.我想在视图寻呼机中显示图像,但延迟加载不能使用它.请给我任何解决方案.我尝试了很多延迟加载文件,但有些正在运行.有些人持有UI.

我现在使用的代码工作正常,但没有第一次显示图像.我必须向下滚动列表视图然后向上滚动然后才显示.我不知道有什么问题请给我解决一下我要做的事情？

我发布我的适配器代码： –

这是我的getvIEw代码：

解决方法:

首先……我不太确定这有多严重,因为你试图使用vIEw pager作为列表视图项.这并不是说它无法实现,而只是在这里有太多的层次.希望你会欣赏这段代码的工作和努力,我希望这将有助于解决你的问题.所以请享受代码.. 总结
