How can I fix problem or can I reset Android Studio settings?
回答1:
Just got the same problem as yours. And this is the solution:
Go to File > Settings > Editor > General > Appearance, then uncheck the Use block caret
回答2:
Try fn + ins. That worked for me.
回答3:
Press Fn + Del on your keyboard together. Explanation: Its because Delete key on keyboard has Insert function. So pressing Del along with Fn key will enable Insert mode within your editor from Overwrite mode as in your case.
回答4:
It's ins in the latest version of Android Studio.

Just restart Android Studio and voilà !
None of the other solutions worked for me (Windows 7, maybe with an inactive Lock Num key).
