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.
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));
Example: Applying this approach to the example value of -16776961:
int intColor = -16776961; String hexColor = String.format("#%06X", (0xFFFFFF & intColor));
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.
