From this discussion I found that it's impossible to get that information on Android. And also I used many task managers on Android and none of them didn't provide such data (they show only memory usage).

Update:

Looks like your question is duplicate to this one.

So all you need to do is to analyze file /proc/<pid>/stat to get CPU usage.

Update #2:

From source Android top.c I found how to get process usage in function print_procs:

proc->delta_time * 100 / total_delta_time
