Android模拟器没有检测到正确的屏幕大小?

I am creating an app which requires a different layout for screen sizes. I have been searching for a while and have already added the screen specifications into my manifest, and created a different layout folder for each screen size.

我正在创建一个应用程序，它需要不同的屏幕尺寸布局。我已经搜索了一段时间，并且已经将屏幕规范添加到清单中，并为每个屏幕大小创建了一个不同的布局文件夹。

When I run the emulator from android studio with a tablet emulator it runs the layout-xlarge files as needed. However in all other cases it runs just layout files.

当我使用平板电脑模拟器运行android studio的模拟器时，它会根据需要运行layout-xlarge文件。但是在所有其他情况下，它只运行布局文件。

This is a problem for me because I need the layout-large files to work also.

这对我来说是一个问题，因为我需要布图-大文件也工作。

I was wondering if this has to do with my code or if this is an emulator problem?

我想知道这是否与我的代码有关还是这是一个模拟器问题?

Check your emulated devices sizes, refer to the below:

检查您的仿真设备尺寸，请参阅下面:

xlarge screens are at least 960dp x 720dp

xlarge屏幕至少有960dp x 720dp。

large screens are at least 640dp x 480dp

大屏幕至少是640dp x 480dp

normal screens are at least 470dp x 320dp

正常屏幕至少是470dp x 320dp

small screens are at least 426dp x 320dp

小屏幕至少是426dp x 320dp

That will ensure it is using the right or wrong setting.

这将确保它使用了正确或错误的设置。

Try renaming the layout folder to layout-normal

尝试将布局文件夹重命名为layout-normal。
