| * |
| * <p>Users typically make an explicit request to autofill a screen in two situations: |
| * <ul> |
| * <li>The app disabled autofill (using {@link View#setImportantForAutofill(int)}. |
| * <li>The service could not figure out how to autofill a screen (but the user knows the |
| * service has data for that app). |
| * </ul> |
| * |
| * <p>This flag is particularly useful for the second case. For example, the service could offer |
| * a complex UI where the user can map which screen views belong to each user data, or it could |
| * offer a simpler UI where the user picks the data for just the view used to trigger the |
| * request (that would be the view whose |
| * {@link android.app.assist.AssistStructure.ViewNode#isFocused()} method returns {@code true}). |
| * |
| * <p>An explicit autofill request is triggered when the |
| * {@link android.view.autofill.AutofillManager#requestAutofill(View)} or |
| * {@link android.view.autofill.AutofillManager#requestAutofill(View, int, android.graphics.Rect)} |
| * is called. For example, standard {@link android.widget.TextView} views that use |
| * an {@link android.widget.Editor} shows an {@code AUTOFILL} option in the overflow menu that |
| * triggers such request. |
