我创建了一个应用程序,用户可以插入各种主题和他们的考试日。我的应用程序为存储在数据库中的每个主题提供时间跨度。当为每个主题分配的时间到达时,警报应该与通知一起播放。通知正常,但警报声没有播放。请帮助我。
我的警报管理员课程是:
public class AlarmManager extends BroadcastReceiver {
sampleDatabase appdb;
SQLiteDatabase sqldb;
Cursor cursor;
int today,prev;
Intent in;
@Override
public void onReceive(Context context, Intent intent)
{
NotificationManager manger = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.icon , "Yahrzeit" , System.currentTimeMillis());
in = new Intent(context,FirstAppActivity.class);
in.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, in, 0);
notification.setLatestEventInfo(context, "ALERT!!!!", "Time Over" , contentIntent);
notification.flags = Notification.FLAG_INSISTENT;
appdb = new sampleDatabase(context);
sqldb = appdb.getReadableDatabase();
cursor = sqldb.query(sampleDatabase.TABLE_SEC, null, null, null, null, null, null);
cursor.moveToFirst();
Calendar cal = Calendar.getInstance();
cal.set(Calendar.SECOND, 0);
today = (int)(cal.getTimeInMillis()/1000);
Log.e("Naga","Alarm");
Log.e("today",Integer.toString(today));
prev = 0;
cursor.moveToPrevious();
while(cursor.moveToNext())
{
int dbdate = cursor.getInt(cursor.getColumnIndex(sampleDatabase.ALARMSET));
int id = cursor.getInt(cursor.getColumnIndex(sampleDatabase.ROW_ID));
Log.e("dbdate",Integer.toString(dbdate));
if((dbdate<=today)&&(dbdate>prev))
{
manger.cancelAll();
manger.notify(1, notification);
sqldb.execSQL("DELETE from " + sampleDatabase.TABLE + " where " + sampleDatabase.ROW_ID + "=" + id);
sqldb.execSQL("DELETE from "+sampleDatabase.TABLE_SEC + " where " + sampleDatabase.ROW_ID + "=" + id);
}
prev = dbdate;
}
cursor.close();
sqldb.close();
}
用来调用此报警管理器的代码如下:
alarmintent = new Intent(getApplicationContext(),com.nagainfo.firstAp.AlarmManager.class);
sender = PendingIntent.getBroadcast(getApplicationContext() , 0 , alarmintent , PendingIntent.FLAG_CANCEL_CURRENT | Intent.FILL_IN_DATA);
am = (AlarmManager) getSystemService(ALARM_SERVICE);
am.cancel(sender);
alarmintent = new Intent(getApplicationContext(), com.nagainfo.firstAp.AlarmManager.class);
//alarmintent.putExtra("note","Hebrew");
sender = PendingIntent.getBroadcast(getApplicationContext() , 0 , alarmintent , PendingIntent.FLAG_CANCEL_CURRENT | Intent.FILL_IN_DATA);
am = (AlarmManager) getSystemService(ALARM_SERVICE);
am.setRepeating(AlarmManager.RTC_WAKEUP, alarmtime, 60000, sender);

您尚未指定使用声音。使用此:
notification.defaults=Notification.DEFAULT_SOUND|Notification.DEFAULT_VIBRATE;
如果您不希望振动将其移除。重点是你必须有点明智或他们。所以,如果你想要灯 -
notification.defaults=Notification.DEFAULT_SOUND|Notification.DEFAULT_VIBRATE|Notification.DEFAULT_LIGHTS;

如果有人使用NotificationCompat.Builder,您可以使用:
Uri sound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
notifyBuilder.setSound(sound);
