Android XML: Text Color does not change?

however my text color will not change it's color to black.

I don't know what the problem could be... do you have any idea?

  <TextView
    android:id="@android:id/empty"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"

    android:textColor="#000000"
    android:textColorHint="#000000"
    android:textSize="14sp"
    android:color="#000000" >
