How to change default view in Odoo
No programming is necessary
Activate the developer mode
Depending on the version you can do it in the Settings(versions 10 and newer) or after clicking on the user in the top right corner.
Go to view you want to change
Some people may ask if they should make a backup of their instance? Changing the default view is a safe operation and it is unlikely to break the system. However, the good practice is to get

Again, the position might be slightly different but it is definitely there.
Adjust the Action settings
In the "Views" section you need to update the following:
- View mode with tree
- View Ref. - just change the last word for
Save & enjoy
You might need to refresh the page or even restart the server to see the effects.
Does not work?
I have got n email that my solution does not work for Calendar(Regards Johan:) ). Checked it out and indeed I forgot about one more thing.
Some actions(like the one for calendar) have additional View sequence. Follow the step "Adjust the Action Settings" and scroll down the window until you see the views(as on the image). Now you can drag and drop views to set their sequence.
I don't need to remind you that when you will be writing a module you need to set the sequence in there as well.

Suggested next steps
After updating Odoo all changes made from the front end(Actions, fields etc.) might be wiped out and replaced by default Odoo settings. That it is why it is recommended to create a module for the new features. If you have no time for programming you can buy the module for that for as little as 10 EUR here: https://apps.odoo.com/apps/modules/11.0/product_default_list_view/
