| public static android.content.res.ColorStateList | addFirstIfMissing(android.content.res.ColorStateList colorStateList, int state, int color)If the color state list does not already have an entry matching the
specified state, prepends a state set and color pair to a color state
list.
This is a workaround used in TimePicker and DatePicker until we can
add support for theme attributes in ColorStateList.
final int[][] inputStates = colorStateList.getStates();
for (int i = 0; i < inputStates.length; i++) {

| private static android.content.res.ColorStateList | createFromXmlInner(Resources r, org.xmlpull.v1.XmlPullParser parser, android.util.AttributeSet attrs)Create from inside an XML document. Called on a parser positioned at a
tag in an XML document, tries to create a ColorStateList from that tag.
