/**
 * Flatten a CharSequence and whatever styles can be copied across processes
 * into the parcel./*from w  w w.  ja va2  s. c o  m*/

public static void writeToParcel(CharSequence cs, Parcel p, int parcelableFlags) {

        // before more generic types.  also notice that it uses
        // "if" instead of "else if" where there are interfaces
        // so one object can be several.
