There are multiple ways you can enable or disable line numbers on your IntelliJ IDE regardless of what programming language IDE you are using (Android Studio, Java, or PyCharm for Python),
Let's see some examples to enable line numbers,
1. Using right click at gutter area:
- Move your cursor to the gutter area (left side of any file),
- Right click and select: Show line Numbers,
- The line numbers should be visible.

Note that the above solution is a temporary solution when you restart your IDE it will be gone.
2. Using Search Everywhere Option
- Press Shift Key Twice,
- Type: Show line Numbers,
- Turn ON the option.

3. Using System Preferences,
- Go to IDEA IntelliJ and Select Preferences (this is for macOS, on Windows it may vary),
- Go to Editor -> General -> Appearance,
- Select the checkbox: Show line Numbers

This is a permanent solution, even if you close the IDE and reopen it, you will be able to persist with the change.
