问题
I created new XML file temp.xml, when I tried to add text view in it, no suggestions are shown to me. When I clicked on TextView, TextView gets added with no body. Then I copy paste some code from other file and tried to give size, color etc to TextView editor is not giving me any suggestions(check image link below) I don't know is there any problem with my layout editor or with Android Studio. (I already tried Invalidate cache / Restart solution, not worked )
If you guys faced this problem in past plz help me. Thank You in advance.

There are three suitable answers for this question .
File -> Invalidate Caches / Restart... -> Select Invalidate and Restart
Just navigate to your android studio installation directory, i.e
yourDrive:/.AndroidStudio3.3/systemand DELETE THE CACHE FOLDER ( first close android studio, if its running ).
Then start Android Studio again. Done.
P.S I am using android studio 3.3.
Open the Settings or Preferences dialog: On Windows or Linux, select File > Settings from the menu bar. Navigate to Build, Execution, Deployment > Instant Run. Unchecked the box next to Restart activity on code changes.
