The model is responsible for querying the system for - * activities that can handle the given intent and order found activities - * based on historical data of previous choices. The historical data is stored - * in an application private file. If a client does not want to have persistent - * choice history the file can be omitted, thus the activities will be ordered - * based on historical usage for the current session. - * <p> - * </p> - * For each backing history file there is a singleton instance of this class. Thus, - * several clients that specify the same history file will share the same model. Note - * that if multiple clients are sharing the same model they should implement semantically - * equivalent functionality since setting the model intent will change the found - * activities and they may be inconsistent with the functionality of some of the clients. - * For example, choosing a share activity can be implemented by a single backing - * model and two different views for performing the selection. If however, one of the - * views is used for sharing but the other for importing, for example, then each - * view should be backed by a separate model. - * </p> - * <p> - * The way clients interact with this class is as follows: - * </p> - * <p> - * <pre> - * <code> - * // Get a model and set it to a couple of clients with semantically similar function. - * ActivityChooserModel dataModel = - * ActivityChooserModel.get(context, "task_specific_history_file_name.xml"); - * - * ActivityChooserModelClient modelClient1 = getActivityChooserModelClient1(); - * modelClient1.setActivityChooserModel(dataModel); - * - * ActivityChooserModelClient modelClient2 = getActivityChooserModelClient2(); - * modelClient2.setActivityChooserModel(dataModel); - * - * // Set an intent to choose a an activity for. - * dataModel.setIntent(intent); - * <pre> - * <code> - * </p> - * <p> - * <strong>Note:</strong> This class is thread safe. - * </p> - * - * @hide - */ -class ActivityChooserModel extends DataSetObservable { - - /** - * Client that utilizes an {@link ActivityChooserModel}. - */ - public interface ActivityChooserModelClient { - - /** - * Sets the {@link ActivityChooserModel}. - * - * @param dataModel The model. - */ - public void setActivityChooserModel(ActivityChooserModel dataModel); - } - - /** - * Defines a sorter that is responsible for sorting the activities - * based on the provided historical choices and an intent. - */ - public interface ActivitySorter { - - /** - * Sorts the <code>activities</code> in descending order of relevance - * based on previous history and an intent. - * - * @param intent The {@link Intent}. - * @param activities Activities to be sorted. - * @param historicalRecords Historical records. - */ - // This cannot be done by a simple comparator since an Activity weight - // is computed from history.
