I have an integer that was generated from an android.graphics.Color

The Integer has a value of -16776961

How do I convert this value into a hex string with the format #RRGGBB

Simply put: I would like to output #0000FF from -16776961

Note: I do not want the output to contain an alpha and i have also tried this example without any success

掩码确保你只能得到RRGGBB，并且％06X给你零填充十六进制（总是6个字符长）：

String hexColor = String.format("#%06X", (0xFFFFFF & intColor));

Try Integer.toHexString()

Source: In Java, how do I convert a byte array to a string of hex digits while keeping leading zeros?

I believe i have found the answer, This code converts the integer to a hex string an removes the alpha.

Integer intColor = -16895234;
String hexColor = "#" + Integer.toHexString(intColor).substring(2);

Note only use this code if you are sure that removing the alpha would not affect anything.
