Fix the ArrayIndexOutOfBound issue.

bug:5619774

It was caused by the error of the radian computation for rotation of
the indicator wheel. Originally we assume the angle of the first and the last
indicator in the second-level settings should be the same as predefined
angles. In fact, there was some computational error during rotation.
