我的应用程序能够触发一些通知。
我希望能够检测用户何时更改通知设置,例如何时全局禁用通知设置,何时禁用一个频道或何时切换“允许通知点” ...
我尝试了NotificationListenerService方法:
public class AppNotificationListenerService extends NotificationListenerService {
private static final String TAG = "AppNLS";
@Override
public void onCreate() {
super.onCreate();
Log.d(TAG, "onCreate: ");
}
@Override
public IBinder onBind(Intent intent) {
Log.d(TAG, "onBind: ");
return super.onBind(intent);
}
@Override
public boolean onUnbind(Intent intent) {
Log.d(TAG, "onUnbind: ");
return super.onUnbind(intent);
}
@Override
public void onNotificationPosted(StatusBarNotification sbn) {
super.onNotificationPosted(sbn);
Log.d(TAG, "onNotificationPosted: ");
}
@Override
public void onNotificationRemoved(StatusBarNotification sbn) {
super.onNotificationRemoved(sbn);
Log.d(TAG, "onNotificationRemoved: ");
}
@Override
public void onListenerConnected() {
super.onListenerConnected();
Log.d(TAG, "onListenerConnected: ");
}
@Override
public void onListenerDisconnected() {
super.onListenerDisconnected();
Log.d(TAG, "onListenerDisconnected: ");
}
@Override
public void onNotificationChannelModified(String pkg, UserHandle user, NotificationChannel channel, int modificationType) {
super.onNotificationChannelModified(pkg, user, channel, modificationType);
Log.d(TAG, "onNotificationChannelModified: ");
}
@Override
public void onListenerHintsChanged(int hints) {
super.onListenerHintsChanged(hints);
Log.d(TAG, "onListenerHintsChanged: ");
}
@Override
public void onNotificationPosted(StatusBarNotification sbn, RankingMap rankingMap) {
super.onNotificationPosted(sbn, rankingMap);
Log.d(TAG, "onNotificationPosted: ");
}
@Override
public void onNotificationRemoved(StatusBarNotification sbn, RankingMap rankingMap) {
super.onNotificationRemoved(sbn, rankingMap);
Log.d(TAG, "onNotificationRemoved: ");
}
@Override
public void onNotificationRemoved(StatusBarNotification sbn, RankingMap rankingMap, int reason) {
super.onNotificationRemoved(sbn, rankingMap, reason);
Log.d(TAG, "onNotificationRemoved: ");
}
@Override
public void onNotificationRankingUpdate(RankingMap rankingMap) {
super.onNotificationRankingUpdate(rankingMap);
Log.d(TAG, "onNotificationRankingUpdate: ");
}
@Override
public void onNotificationChannelGroupModified(String pkg, UserHandle user, NotificationChannelGroup group, int modificationType) {
super.onNotificationChannelGroupModified(pkg, user, group, modificationType);
Log.d(TAG, "onNotificationChannelGroupModified: ");
}
@Override
public void onInterruptionFilterChanged(int interruptionFilter) {
super.onInterruptionFilterChanged(interruptionFilter);
Log.d(TAG, "onInterruptionFilterChanged: ");
}
}
在清单中我添加了服务:
<service android:name=".services.AppNotificationListenerService"
android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE" >
<intent-filter>
<action android:name="android.service.notification.NotificationListenerService" />
</intent-filter>
</service>
已正确创建服务绑定,当从通知区域显示/删除通知时,我看到onNotificationPosted()
和onNotificationRemoved()
。
但是,当我全局启用/禁用该应用程序的通知时,不会调用任何方法。而且,当我启用/禁用频道通知时,唯一调用的方法是onNotificationRankingUpdate()
,但是在其他应用程序的频道也切换时会调用此方法。我只需要我的应用程序即可。
这是正确的方法还是我想实现的目标以另一种方式完成?
答案 0 :(得分:1)
如another SO answer中所述,API 28为ACTION_NOTIFICATION_CHANNEL_BLOCK_STATE_CHANGED
和ACTION_NOTIFICATION_CHANNEL_GROUP_BLOCK_STATE_CHANGED
添加了适合您的需求(see documentation)的系统广播。
