问题描述
我有像这样的图像。我可以用旋转this code 。现在，我想知道，哪种颜色有所触动，独立车轮的位置。例如，无论以下职位的车轮是，我应该能够探测到什么颜色我都感动......红色，黄色，绿色，蓝色，粉红色或灰色。可能吗？我该怎么办呢？请帮助我，因为我不知道。是否有任何其他的可能性，而不是使用一个单一的照片吗？（解决方案，我想preFER避免...）
I have an image like this one. I can rotate it using this code. Now I would like to know, which color has been touched, independently of the wheel's position. For example, whatever of the following positions the wheel is in, I should be able to detect what color I have touched ...red, yellow, green,blue,pink or grey. Is it possible? How can I do it? Please help me, because I have no idea. Is there any other possibility instead of using a single picture?(solution I would prefer to avoid...)
或或或任何...
or or or whatever...
更新：我张贴一些的颜色，因为我想成为更加明确，我得到了一个解决方案，但我怎么能这样做，如果我有不同的图像而不是颜色。
UPDATE: I post some colors because I wanted to be more clear, and I got a solution for this, but how could I do if I have different images instead of a color.
推荐答案
德code的X＆放大器;触摸事件的y位置然后调用getPixel的位图：
Decode the x & y position of the touch event then call getPixel on the Bitmap:http://developer.android.com/reference/android/graphics/Bitmap.html
