Dear friends, I am developing a small app that should inform the drivers whether his current speed matches the preferred one in order to avoid stopping for the red light.
I have no probelms to calculate the relative speed of the vehicle and compare it with the preferred speed in order to determine and inform the driver whether his speed is appropriate for crossing the traffic light when it is green, or he needs to slow down or speed up. But, I would be very thankful if you can help me to display this graphically. My current idea is to draw a traffic light (in red and green) on the screen in .xml, using 11 equally sized bars. Hereby, I can show whether the speed fits perfectly (then bar 6 should be black), or there is no room for delay (then bar 4 should be black) So far, I have made the traffic light in .xml. My next step is to change the color of one of the bars dependent on how the relative speed matches the shifts in the traffic light. In theory it seems to be easy, but I would highly appreciate your help on how to do this in Android as I cannot see how I start changing the colours of the individual bar in the screen after initially defining the screen. There might be other and better ways to implement this than .xml I would appreciate your help; Best regards ckloch -- You received this message because you are subscribed to the Google Groups "Android Beginners" group.
