Transformation,
Parcelable
java.lang.Object | |
↳ | android.service.autofill.CharSequenceTransformation |
Replaces a TextView
child of a CustomDescription
with the contents of one or
more regular expressions (regexs).
When it contains more than one field, the fields that match their regex are added to the overall transformation result.
For example, a transformation to mask a credit card number contained in just one field would be:
new CharSequenceTransformation .Builder(ccNumberId, Pattern.compile("^.*(\\d\\d\\d\\d)$"), "...$1") .build();
But a transformation that generates a Exp: MM / YYYY
credit expiration date from two
fields (month and year) would be:
new CharSequenceTransformation .Builder(ccExpMonthId, Pattern.compile("^(\\d\\d)$"), "Exp: $1") .addField(ccExpYearId, Pattern.compile("^(\\d\\d\\d\\d)$"), " / $1");

describeContents
public int describeContents ()
Describe the kinds of special objects contained in this Parcelable
instance's marshaled representation. For example, if the object will
include a file descriptor in the output of writeToParcel(android.os.Parcel, int)
,
the return value of this method must include the
CONTENTS_FILE_DESCRIPTOR
bit.
Returns | |
