Roughly the same as: I have no desire to do an activity this week.

These would all be roughly equivalent to "don't feel like": Have no desire, no aspiration, no motivation, no appetite for...

"No mind for" would be a bit vague. I think that would mean maybe: Not thinking about

The "activity" is usually referring to something earlier in the conversation.

"Doing something" is interchangeable with "doing anything", "doing an activity", etc.
