我不知道为什么但是当我使用NestedScrollView时,我的应用程序开始挂起,然后出现“应用程序没有响应”弹出窗口。我甚至没有在日志中收到任何错误。这是XML代码:

当我删除NestedScrollView时,该应用程序正常工作。我不知道我做错了什么?这是我在日志上得到的:

答案 0 :(得分:0)
此行为似乎与缺少的依赖项有关。您是否以compile 'com.android.support:recyclerview-v7:22.2.0'
为例或配置了其他依赖项(例如“in.mylo.pregnancy.baby.CustomSpinner”不可用)?
重要的一点我在你的日志中注意到,我看到很多内存消耗。可能是应用程序也在执行一些后台逻辑。我的建议是尝试在没有“in.mylo.pregnancy.baby.CustomSpinner”的情况下运行你的app,看看它是否会导致这个问题发生。
希望这有帮助。
