我很努力调试我的Android应用程序中的列表视图奇怪的UI故障。 99%的时间一切看起来和像它应该的工作,但时不时地我的列表视图奇怪。当你重新启动应用程序时,listview再次看起来很正常。自定义列表视图奇怪的UI故障
有谁知道这是不是一个已知的android bug?
事实上,它只发生在随机(我试图找出一个模式和不能)我吓坏了。我还没有找到任何关于类似问题的在线信息。希望我刚刚搜索错误的搜索条件。
任何意见/帮助将不胜感激。
在此先感谢。

在xml中使用wrap_content – 2014-08-27 13:32:10
您可以评论每个视图的XML是什么?很难看到每张照片在视觉上代表什么。例如,您有3个TextView,但只能在图片中看到2个 – 2014-08-27 13:32:58
另外,您应该使用MATCH_PARENT,除非您需要支持API <8 – 2014-08-27 13:35:20
