android开发中int型的颜色值转化为string

Question

int color = Color.成YELLOW;
如何把color转化为#20540形式？

Answer 1

private String getHexString(int color) {
String s = "#";
int colorStr = (color & 0xff000000) | (color & 0x00ff0000) | (color & 0x0000ff00) | (color & 0x000000ff);
s = s + Integer.toHexString(colorStr);
return s;
}
