Transforming Color Integers to Hex Strings in Android

Converting color integers generated by android.graphics.Color to hex strings in #RRGGBB format can be a common requirement in Android development. To simplify this process, we'll explore a method that removes alpha values and ensures zero padding.

Approach

1. Create a Hex String: To obtain the hex string, we utilize the String.format method with a specific format string:

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

   • The # prefix identifies the hex value.
   • X controls the format of the hex string, specifying 6 hexadecimal digits (zero-padded if necessary).
   • (0xFFFFFF & intColor) masks out the alpha channel, ensuring you only get the RRGGBB components.

2. Example: Applying this approach to the example value of -16776961:

   int intColor = -16776961;
   String hexColor = String.format("#%06X", (0xFFFFFF & intColor));

   • The code will produce `"#0000FF," which matches the desired output.

By following these steps, you can easily convert color integers to hex strings in Android, ensuring the absence of alpha values and proper zero-padding for a uniform hexadecimal representation.
