Android的：如何填充颜色只有图像的特定部分？ [英] Android: How to fill color to the specific part of the Image only?

问题描述

我有图片如下：

现在，我要填充的颜色到图像的特定部分。像如果我选择的颜色蓝色，如果我触及上限则盖应填充蓝色。同样的事情也应该是发生在其他部分一样的鼻子，嘴巴，眼睛等

Now, i want to fill the color to the Specific part of that image. as like If i select color blue and if i touch on Cap then the cap should be fill with the color Blue. Same thing should be also happen with the other part like nose, Mouth, Eyes etc

那么，它是如何可能使用Android的？

So, How it is possible using android ?

可以在任何budy帮我请。

Can any budy help me please.

我尝试用此时，floodFill算法在我的应用程序的执行情况。 看到这里

I have try with the implementation of the FloodFill algorithm in my app. See Here

但这样做，我得到异常等之后：

But after doing that i got exception like:
