Hi Rasum. There are a few ways to use colours in XML:

  • using one of the pre-defined colours from the Android system. For example: android:textColor="@android:color/white"
  • using the hex colour codes. For example android:textColor="#fff092b0"(although hardcoding values is not best practice, better use the next option)
  • using the colors.xml resource file, just as we use the strings.xml resource file instead of hardcoding strings. For example: android:textColor="@color/primaryColor"

I hope that helps you complete the challenge :)
