Interactive Notifications List

Uses the Qt Android Notifications Listener QML API to make an interactive notifications list.

"Notifications List"

This example demonstrates how to use the Qt Android Notifications Listener QML API to show a list of active notifications in an Android or Android Automotive device, and interact with them.

When the app is started, a list of the active notifications on the device is shown in a ListView. When new notifications are posted or old ones removed, the list will be updated. There are also various ways of interacting with the notifications: you can dismiss ones that are clearable, and launch any actions provided with the notification.

Running the Example

To run the example from Qt Creator, open the Welcome mode and select the example from Examples. For more information, visit Building and Running an Example.

Enabling notification listener

When the app is started, if it hasn't been granted access to notifications the Android settings page for notification access will be opened. To use the app, grant it access to notifications.

Note: If you do not grant access to the app, it will not receive any notifications.

Note: Due to the underlying Android API used, the app cannot reliably check whether the app has been granted access if the used API level is below 27 (Android 8.1). In this case, it will always evaluate the access to be granted, and the setting page will not be opened. In this case, you can navigate to the correct settings page and grant access. It can be found under Settings -> Apps & Notifications -> Special app access -> Notification access.

Once access has been granted, the app will start receiving the notifications, and have access to pre-existing ones.

Using the Model

The notification model is based on a QAbstractListModel from C++ and it is extended to QML. The model can be used with ListView or GridView as needed.

In this example, a ListView is used. The model is attached to the view as follows:

    ListView {
        id: listView

        anchors.fill: parent

        model: AndroidNotificationListener.notificationsModel

Then, we set the list's delegate to use a custom delegate:

        delegate: NotificationDelegate {
            width: listView.width
            notificationId: model.notificationId
            key: model.key
            packageName: model.packageName
            title: model.title
            content: model.content
            clearable: model.clearable
            uriEncodedIcon: model.iconSmall
            actions: model.actions

Finally, when the ListView component is completed, we start the notification listener:

    Component.onCompleted: AndroidNotificationListener.start()

Using the API Calls

Inside the NotificationDelegate, we can interact with the posted notifications. When the delegate item is clicked, it will invoke the content intent of the notification, if one has been provided:

    onClicked: AndroidNotificationListener.launchContentIntent(root.key)

If any additional actions have been provided with the notification, a Button will be added for each one, and clicking on it will trigger the action:

                delegate: Button {
                    text: root.actions[index].title
                    icon.source: root.actions[index].icon
                    onClicked: root.actions[index].performAction()

And when the notification is swiped, it will be dismissed:

            function onCompleted() { AndroidNotificationListener.dismissNotification(root.key) }
