Android ImageView实现反色显示的方法

假设你的按钮imageView用的是矢量图标，图案颜色是黑白的：
当你点选他之后，可以用以下方法让它黑白反色显示： void selectedColor(ImageView i,int backgroundColor,int iColor){//后两个参数一个是背景色的16进制int值，最后一个是图案的颜色16进制值 i.setBackgroundColor(0xFFFFFFff-backgroundColor+0xFF000000);//设置此按钮的背景色，这里采用了反色算法，需要注意的是头两个FF是透明度，如果要保持透明度不变的话就得在后面把它（0xFF000000）加回去。 i.setImageTintList(ColorStateList.valueOf(0xFFFFFFff-iColor+0xFF000000));//设置此按钮图案的颜色} 反色显示后的效果如下：
