Android 8.0实现发送通知
在Android8.0以后，针对Notification通知api做了修改，新增了通知渠道（NotificationCannel)。下面就把demo的详细代码记录下：
1.Application为NotificationManager添加通知频道
importandroid.app.Application;
importcom.xinrui.ndkapp.notification.NotificationChannels;
publicclassNdkApplicationextendsApplication{
@Override
publicvoidonCreate(){
super.onCreate();
NotificationChannels.createAllNotificationChannels(this);
}
}
2.NotificationChannels类
publicclassNotificationChannels{
publicfinalstaticStringCRITICAL="critical";
publicfinalstaticStringIMPORTANCE="importance";
publicfinalstaticStringDEFAULT="default";
publicfinalstaticStringLOW="low";
publicfinalstaticStringMEDIA="media";
publicstaticvoidcreateAllNotificationChannels(Contextcontext){
NotificationManagernm=(NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
if(nm==null){
return;
}
NotificationChannelmediaChannel=newNotificationChannel(
MEDIA,
context.getString(R.string.app_name),
NotificationManager.IMPORTANCE_DEFAULT);
mediaChannel.setSound(null,null);
mediaChannel.setVibrationPattern(null);
nm.createNotificationChannels(Arrays.asList(
newNotificationChannel(
CRITICAL,
context.getString(R.string.app_name),
NotificationManager.IMPORTANCE_HIGH),
newNotificationChannel(
IMPORTANCE,
context.getString(R.string.app_name),
NotificationManager.IMPORTANCE_DEFAULT),
newNotificationChannel(
DEFAULT,
context.getString(R.string.app_name),
NotificationManager.IMPORTANCE_LOW),
newNotificationChannel(
LOW,
context.getString(R.string.app_name),
NotificationManager.IMPORTANCE_MIN),
//customnotificationchannel
mediaChannel
));
}
}
3.发送通知
publicvoidsendSimpleNotification(Contextcontext,NotificationManagernm){
//创建点击通知时发送的广播
Intentintent=newIntent(context,NotificationMonitorService.class);
intent.setAction("android.service.notification.NotificationListenerService");
PendingIntentpi=PendingIntent.getService(context,0,intent,0);
//创建删除通知时发送的广播
IntentdeleteIntent=newIntent(context,NotificationMonitorService.class);
deleteIntent.setAction(Intent.ACTION_DELETE);
PendingIntentdeletePendingIntent=PendingIntent.getService(context,0,deleteIntent,0);
//创建通知
Notification.Buildernb=newNotification.Builder(context,NotificationChannels.DEFAULT)
//设置通知左侧的小图标
.setSmallIcon(R.drawable.ic_notification)
//设置通知标题
.setContentTitle("Simplenotification")
//设置通知内容
.setContentText("Demoforsimplenotification!")
//设置点击通知后自动删除通知
.setAutoCancel(true)
//设置显示通知时间
.setShowWhen(true)
//设置通知右侧的大图标
.setLargeIcon(BitmapFactory.decodeResource(context.getResources(),R.drawable.ic_notifiation_big))
//设置点击通知时的响应事件
.setContentIntent(pi)
//设置删除通知时的响应事件
.setDeleteIntent(deletePendingIntent);
//发送通知
nm.notify(Notificaitons.NOTIFICATION_SAMPLE,nb.build());
}
