我希望每天12小时重复我的通知,但我的代码无效... 我在OnCreate的MainActivity中启动我的Alarm Manager,如下所示:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_ma);
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 12);
calendar.set(Calendar.MINUTE, 00);
calendar.set(Calendar.SECOND, 0);
Intent intent1 = new Intent(MainActivity.this, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0,intent1, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager am = (AlarmManager) MainActivity.this.getSystemService(MainActivity.this.ALARM_SERVICE);
am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
和我的AlarmReceiver类:
public class AlarmReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
long when = System.currentTimeMillis();
NotificationManager notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
Intent notificationIntent = new Intent(context, MainActivity.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder mNotifyBuilder = new NotificationCompat.Builder(
context).setSmallIcon(R.drawable.photo)
.setContentTitle("ça marche fdp")
.setContentText("Et ouai t'as bien réussi à afficher une notification bordel de cul").setSound(alarmSound)
.setAutoCancel(true).setWhen(when)
.setContentIntent(pendingIntent)
.setVibrate(new long[]{1000, 1000, 1000, 1000, 1000});
notificationManager.notify(0, mNotifyBuilder.build());
}
}
你知道问题出在哪里吗?请不要不喜欢我只想学习代码:(
答案 0 :(得分:1)
更新您的清单文件,以便为您的接收器提供以下参数:
<receiver
android:name="com.example.alarmmanagernotifcation.AlarmReceiver"
android:enabled="true"
android:process=":remote" />
然后我相信问题可能出在您选择的图标上:
.setSmallIcon(R.drawable.photo)
如果图像不兼容,那么你不会在应用程序外看到崩溃,如果手机已插入,它只会在Android监视器内部显示致命异常,因此它可以被忽视并且通知不会被解雇。
使用的drawable需要针对不同的手机密度具有不同的尺寸。要制作正确的drawable,请右键单击drawable
包,然后执行New - &gt;图像资产。从下拉菜单中选择通知图标,然后使用它生成图标的所有不同大小。
