Note that we want to make the full row clickable, so we are setting the click listener on the root element of collection_widget_list_item. Here we are filling the pending intents template defined in CollectionAppWidgetProvider class. Intent fillInIntent = new Intent ( ) įillInIntent.

Then fill this template every time a new RemoteViews object is created by the RemoteViewsFactory.Īdd this code in getViewAt method in MyWidgetRemoteViewsFactory class. And have the Firestore document be cast to a custom java class I made. The items are added automatically using Adapter. It shows the list in vertical form and it becomes scrollable automatically. It is the most basic but one of the most important UI components in Android. In ListView the list layout is created using ListView. widgetListView, clickPendingIntentTemplate ) įor each ListView item we are launching DetailsActivity which will simply display the task description sent as an extra.

Click events on ListView itemsĪdding click events on ListView items is not as simple as setting up the setOnItemClickListener on the ListView object.

Uno dei controlli grafici fondamentale e più utilizzato nella piattaforma Android è certamente la ListView. It shows the data in different views like GridView, ListView, Spinners, etc. The idea here is similar to how we add click events in our apps. It also retrieves data from data set & generates view objects based on that data. public class MyWidgetRemoteViewsFactory implements RemoteViewsService. Create a new Java class, name it MyWidgetRemoteViewsFactory, and set it to implement the class RemoteViewsService.RemoteViewsFactory. An adapter is used to connect the collection items(for example, ListView items or GridView items) with the data set. RemoteViewsFactory serves the purpose of an adapter in the widget’s context.
