You're in Packagesview and putting all your files in the wrong folder. Switch to Projectview (left hand, top side toggle). Under app, you should see a folder called src-> main-> java-> com.example.prateek. That's where all your class files should properly be to avoid autodeletion.
您正在Packages查看并将所有文件放在错误的文件夹中。切换到Project视图（左手，顶部切换）。在 下app，您应该会看到一个名为src-> main-> java->的文件夹com.example.prateek。这就是所有类文件都应该正确放置的地方，以避免自动删除。

This happens due to incorrect Source folder mappings done by some mistake.
发生这种情况是由于某些错误导致的源文件夹映射不正确。
In order to resolve the same, please go to
为了解决相同的问题，请转到
Project Structure -> Project Settings -> Modules.
Select the Module that has this issue and select the Sources Tab
On the Right Hand Side you will find Add Content Root pane. Please Check if the Source and Test Folders are mapping to the correct root and there is no other mapping present apart from the valid root mapping [For eg src for Source Folders and tst for Test Source Folders.]
Delete any unwanted mapping present in either of them. Apply and Re sync the project.
选择有此问题的模块，然后选择 Sources 选项卡
在右侧，您将找到“添加内容根”窗格。请检查源文件夹和测试文件夹是否映射到正确的根目录，并且除了有效的根映射之外没有其他映射 [例如，源文件夹的 src 和测试源文件夹的 tst。]
删除其中任何一个中存在的任何不需要的映射。应用并重新同步项目。
Issue should be solved now.
问题现在应该解决了。
