回答1:
Yes it already exist.
you have to change the project structure
Click on top left dropdown where Android Appears.
Select project from this dropdown and you will be able to see all drawbale folders.
回答2:
Its because you might not have any files inside your res/drawable-xxx folders
To access them, change your project navigation:
To do so, check the top left pane for some written as 1 Project click on that or alternatively press Alt+1 here, if you see the default selection will be Android with an android bot click on the two left-right arrow icons select Project Files and then navigate!

You do not need to explicitly create the drawable folders for different resolutions. Whenever you will add any image to the project's drawable folder, by clicking right on the drawable folder and pasting the image there, a dialog will open up, that will ask you to select from drawable-hdpi, drawable-mdpi, drawable-xhdpi, and drawable-xxhdpi. You can then select the suitable one from the drop down, and you will be able to see the distinctions within the drawable folder itself.
