屏蔽颜色的android [英] Masking color android

问题描述

我想在Android的图像透明的，所以我做了一些研究，但得出的结论，我真的did'nt得到它。所以我吸取了我的画布一对夫妇的位图，以及1种位图我想要的红色透明。我发现了一张code，但我并没有真正做任何事情。这是我的code：

 如果（PictureArray [A] == 0）{
                油漆删除=新的油漆（）;
                Remove.setARGB（255，255，0，0）;
                INT removeColor = Remove.getColor（）;
                Remove.setAlpha（0）;
                Remove.setXfermode（新AvoidXfermode（removeColor，0，AvoidXfermode.Mode.TARGET））;
                c.drawBitmap（石，X，c.getHeight（）/ 2，NULL）;
            }
 

解决方案

使用一个透明的PNG。无需overengineer它;）

I want to make an image transparent in android, so I did some research but came to the conclusion that I did'nt really get it. So I am drawing A couple of bitmaps on my canvas, and in 1 kind of bitmap I want to make the red transparent. i found A piece of code but I doesn't really do anything. this is my code:

if(PictureArray[a]==0){
                Paint Remove = new Paint();
                Remove.setARGB(255, 255, 0, 0);
                int removeColor=Remove.getColor();
                Remove.setAlpha(0);
                Remove.setXfermode(new AvoidXfermode(removeColor,0,AvoidXfermode.Mode.TARGET));
                c.drawBitmap(Stone, x, c.getHeight()/2, null);
            }

解决方案
