Now in the left coloum of the editor you can see many folders (Manifest,java,res etc) .

 

 

from the folders, select “res” folder, in this folder is where the android main view layouts stored

 

in the res folder, you can see some other folders, select “Layout” folder  and double click on the “activity_main.xml” file, it will be opened in the editor
