Android8.0系统的通知需要Channel创建,记录笔记:
//显示通知栏
private void showFloat(String message) {
if (UserInfoManager.getInstance().getMsgActive()) {
return;
}
NotificationManager mManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Notification notification;
Intent intent = new Intent(this, MessageActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel mChannel = new NotificationChannel("default", "name", NotificationManager.IMPORTANCE_HIGH);
mChannel.setShowBadge(true);
mChannel.enableLights(true);
//2.0 把通知渠道通过createNotificationChannel()
mManager.createNotificationChannel(mChannel);
//3.0 Notification这时候可以正常工作了
notification = new NotificationCompat.Builder(this, "default")
.setContentTitle("标题")//设置通知栏标题
.setContentText(message) //设置通知栏显示内容
.setWhen(System.currentTimeMillis())//通知产生的时间。
.setSmallIcon(R.mipmap.app_icon)//设置通知小ICON
.setDefaults(NotificationManager.IMPORTANCE_HIGH)
.setPriority(NotificationManager.IMPORTANCE_HIGH)
.setAutoCancel(true)
.setDefaults(Notification.DEFAULT_ALL)
//.setFullScreenIntent(pendingIntent, true)
.setContentIntent(pendingIntent)
.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.app_icon))//设置通知大ICON
.build();
} else {
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, "default")
.setContentTitle("标题")
.setContentText(message)
.setWhen(System.currentTimeMillis())//通知产生的时间。
.setSmallIcon(R.mipmap.app_icon)
.setDefaults(NotificationCompat.PRIORITY_HIGH)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setDefaults(NotificationCompat.DEFAULT_SOUND)
.setAutoCancel(true)
.setContentIntent(pendingIntent)
//.setFullScreenIntent(pendingIntent, true)
.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.app_icon));
notification = notificationBuilder.build();
}
mManager.notify(1, notification);
}
.setAutoCancel(true)表示点击通知栏就自动消失,
如果在退出App的时候需要取消掉通知,可以调用
if (mManager != null) { //取消通知 mManager.cancelAll(); }
下面是检查是否有通知权限,和进入设置的方法:
//是否有通知权限
public static boolean isOpenNotify(Context context) {
boolean isOpened = false;
try {
NotificationManagerCompat from = NotificationManagerCompat.from(context);
isOpened = from.areNotificationsEnabled();
} catch (Exception e) {
e.printStackTrace();
}
return isOpened;
}
//前往设置
public static void goToSetNotify(Context context) {
if(Build.VERSION.SDK_INT >=26) {
Intent intent = new Intent();
intent.setAction(Settings.ACTION_APP_NOTIFICATION_SETTINGS);
intent.putExtra(Settings.EXTRA_APP_PACKAGE,context.getPackageName());
context.startActivity(intent);
} else {
Intent intent = new Intent();
intent.setAction("android.settings.APP_NOTIFICATION_SETTINGS");
intent.putExtra("app_package",context.getApplicationContext().getPackageName());
intent.putExtra("app_uid",context.getApplicationInfo().uid);
context.startActivity(intent);
}
}
