CharSequenceTransformation

class CharSequenceTransformation : Transformation, Parcelable
kotlin.Any
   ↳ 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");
