Android Studio 中的所有活动和布局都已损坏 [英] All Activities and layouts got corrupted in Android Studio

问题描述

我从 3 个月开始就在做一个项目.今天，我的大部分活动和 xml 文件都已损坏.我曾尝试删除workspace.iml 文件，但它仍然相同.VCS 中的本地历史记录也是空的.有什么办法可以恢复我的代码或解决这个问题.注意如果我在记事本 app/scrc/main/activity.java 中打开这些文件，则这些文件与以前相同，但在 Android Studio 中显示不同

I am working on a projects since 3 months. Today most of my activities and xml files got corrupted. I have tried deleting workspace.iml file but it remains same.Local History in VCS is also empty. Is there any way to recover my code or solve this issue. Note These files are same as previous if I open then in Notepad app/scrc/main/activity.java, but showing different in Android studio

这是我的代码现在的样子

推荐答案

今天早上我也遇到了同样的问题.我认为这是由于迁移到 AndroidX 但那是错的.它可能由于不正确的索引和构建而发生，例如索引是强制停止的.或由于某些 IDE 问题.

I also had the same problem this morning. I thought this was due to migrating to AndroidX but It was wrong. It may occur due to improper indexing and building for e.g. the indexing is force stopped. or due to some IDE issues.

问题通过删除项目中的gradle和.idea文件夹解决并通过 D:\Users\ABCD.AndroidStudio3.2\system\caches 清除 Android Studio IDE 的缓存.问题已解决.

注意:-请每天进行项目备份.

Note:- Please take Project Backups Daily.
