The {@link AutofillManager} class provides ways for apps and custom views to * integrate with the Autofill Framework lifecycle. * *
To learn about using Autofill in your app, read * the Autofill Framework guides. * *
The autofill lifecycle starts with the creation of an autofill context associated with an * activity context. The autofill context is created when one of the following methods is called for * the first time in an activity context, and the current user has an enabled autofill service: * *
Typically, the context is automatically created when the first view of the activity is * focused because {@code View.onFocusChanged()} indirectly calls * {@link #notifyViewEntered(View)}. App developers can call {@link #requestAutofill(View)} to * explicitly create it (for example, a custom view developer could offer a contextual menu action * in a text-field view to let users manually request autofill). * *
After the context is created, the Android System creates a {@link android.view.ViewStructure} * that represents the view hierarchy by calling * {@link View#dispatchProvideAutofillStructure(android.view.ViewStructure, int)} in the root views * of all application windows. By default, {@code dispatchProvideAutofillStructure()} results in * subsequent calls to {@link View#onProvideAutofillStructure(android.view.ViewStructure, int)} and * {@link View#onProvideAutofillVirtualStructure(android.view.ViewStructure, int)} for each view in * the hierarchy. * *
The resulting {@link android.view.ViewStructure} is then passed to the autofill service, which * parses it looking for views that can be autofilled. If the service finds such views, it returns * a data structure to the Android System containing the following optional info: * *
When the service returns datasets, the Android System displays an autofill dataset picker * UI associated with the view, when the view is focused on and is part of a dataset. * The application can be notified when the UI is shown by registering an * {@link AutofillCallback} through {@link #registerCallback(AutofillCallback)}. When the user * selects a dataset from the UI, all views present in the dataset are autofilled, through * calls to {@link View#autofill(AutofillValue)} or {@link View#autofill(SparseArray)}. * *
When the service returns ids of savable views, the Android System keeps track of changes * made to these views, so they can be used to determine if the autofill save UI is shown later. * *
The context is then finished when one of the following occurs: * *
Finally, after the autofill context is commited (i.e., not cancelled), the Android System * shows an autofill save UI if the value of savable views have changed. If the user selects the * option to Save, the current value of the views is then sent to the autofill service. * *
It is safe to call AutofillManager
methods from any thread.
