Converting Color Integer to Hex String in Android

When working with colors in Android, it's often necessary to convert between their integer representation and hex string format. Suppose you have an integer (-16776961) representing a color and need to convert it into a hex string in the format #RRGGBB.

Solution:

To convert the color integer into a hex string, follow these steps:

1. Create a mask to isolate RRGGBB:

   int mask = 0x00FFFFFF;

   Copy after login

2. Apply the mask to the color integer:

   int intColor = -16776961;
   int strippedColor = intColor & mask;

   Copy after login

3. Convert the stripped color to a hex string (zero-padded to 6 characters):

   String hexColor = String.format("#%06X", strippedColor);

   Copy after login

Example:

Applying these steps to the given integer (-16776961) will result in the hex string "#0000FF". This represents a pure blue color with no alpha component.
