Remarks
Defines a custom description for the autofill save UI.
This is useful when the autofill service needs to show a detailed view of what would be saved; for example, when the screen contains a credit card, it could display a logo of the credit card bank, the last four digits of the credit card number, and its expiration number.
A custom description is made of 2 parts: <ul> <li>A RemoteViews presentation template containing children views. <li>Transformation Transformations to populate the children views. </ul>
For the credit card example mentioned above, the (simplified) template would be:
<LinearLayout>
<ImageView android:id="@+id/templateccLogo"/>
<TextView android:id="@+id/templateCcNumber"/>
<TextView android:id="@+id/templateExpDate"/>
</LinearLayout>
Which in code translates to:
CustomDescription.Builder buider = new Builder(new RemoteViews(pgkName, R.layout.cc_template);
Then the value of each of the 3 children would be changed at runtime based on the the value of the screen fields and the Transformation Transformations:
// Image child - different logo for each bank, based on credit card prefix
builder.addChild(R.id.templateccLogo,
new ImageTransformation.Builder(ccNumberId)
.addOption(Pattern.compile("^4815.*$"), R.drawable.ic_credit_card_logo1)
.addOption(Pattern.compile("^1623.*$"), R.drawable.ic_credit_card_logo2)
.addOption(Pattern.compile("^42.*$"), R.drawable.ic_credit_card_logo3)
.build();
// Masked credit card number (as .....LAST_4_DIGITS)
builder.addChild(R.id.templateCcNumber, new CharSequenceTransformation
.Builder(ccNumberId, Pattern.compile("^.*(\\d\\d\\d\\d)$"), "...$1")
.build();
// Expiration date as MM / YYYY:
builder.addChild(R.id.templateExpDate, new CharSequenceTransformation
.Builder(ccExpMonthId, Pattern.compile("^(\\d\\d)$"), "Exp: $1")
.addField(ccExpYearId, Pattern.compile("^(\\d\\d)$"), "/$1")
.build();
See ImageTransformation, CharSequenceTransformation for more info about these transformations.
