First of all, Africa is a big place. So there are many examples of both resistance and collaboration. The Europeans employed Divide & Conquer tactics very pragmatically. They'd play out already existing rivalries, and place minority groups in power (since they rely more heavily on the Europeans to stay in power, they'd be more cooperative.)

Take German South West Africa for example; The Herero people signed a protection treaty with Germany, hoping for help against their pesky cattle stealing rivals. When after a couple years the Germans failed to provide help against these rivals they rebelled. Also land ownership didn't exist, and the Germans could just claim any land they wanted. For more on this there is a well sourced Wikipedia article.

If you want to take it for Africa as a whole i found a book partially readable on Google books by Muriel Evelyn Chamberlain, The scramble for Africa. I could also recommend Divide and rule : the partition of Africa, 1880-1914 by Henk Wesseling, I could'nt find that online for you though, so you'd have to be a real historian and go to a library to get it.
