the views of my interface are not shown in the android editorLayout help, thanks ] 1
How about the exclamation that you have above the editor on the right is due to an error render by the appcompat so what you should do is within the gradle: app module in dependencies change the following:
implementation 'com.android.support:appcompat-v7:27.0.0'
In that line you put the last number and put it back as it is after the sync and ready. Salu2
