我正在尝试在不同的特定时间实施重复的多个警报。 问题是在任何给定时间都没有调用警报接收器。
我在活动中的代码:
private void setAlarms() {
Intent myIntent=new Intent(this, AlarmReceiver.class);
myIntent.putExtra("MedName",medication_name);
myIntent.setAction("b5.project.medibro.receivers.AlarmReceiver");
AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
//am.set(AlarmManager.RTC_WAKEUP, time, pendingIntent);
ArrayList<PendingIntent> intentArray = new ArrayList<PendingIntent>();
int counter=0;
for(String timer: timers){
//timers is an array of Strings in the format hh:mm
try {
String[] comps=timer.split(":");
Calendar cal=Calendar.getInstance();
cal.set(Calendar.HOUR_OF_DAY, Integer.valueOf(comps[0]));
cal.set(Calendar.MINUTE, Integer.valueOf(comps[1]));
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);
Log.d(TAG,comps[0]+" "+comps[1]+ "Alarm Time: " + cal.getTime().toString());
PendingIntent pendingIntent = PendingIntent.getService(this, counter, myIntent,0);
am.setInexactRepeating(AlarmManager.RTC_WAKEUP,
cal.getTimeInMillis(),
AlarmManager.INTERVAL_DAY,
pendingIntent);
counter++;
} catch (ParseException e) {
e.printStackTrace();
Log.d(TAG,"Time Parsing error: "+e.getMessage());
}
}
}
这是我的闹钟接收器:
public class AlarmReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
if(intent.getAction().equals("b5.project.medibro.receivers.AlarmReceiver")) {
Toast.makeText(context, "I'm running", Toast.LENGTH_SHORT).show();
Log.d("Alarm Receiver", "Alarm is invoked. ");
NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
builder.setSmallIcon(R.drawable.messenger_bubble_large_blue);
builder.setContentTitle("Time to take your medicine");
String medName = intent.getStringExtra("MedName");
String text = "Medicine name: " + medName;
builder.setContentText(text);
Notification notification = builder.build();
NotificationManagerCompat.from(context).notify(0, notification);
Toast.makeText(context, "I'm running", Toast.LENGTH_SHORT).show();
}
}
}
清单声明:(在应用程序标记内)
<receiver android:name="b5.project.medibro.receivers.AlarmReceiver"
android:enabled="true">
<intent-filter>
<action android:name="b5.project.medibro.receivers.AlarmReceiver"/>
</intent-filter>
</receiver>
我觉得上面的代码应该至少执行一次广播接收器,但是没有任何东西出现在logcat中。 有人能告诉我我错过了什么吗?
答案 0 :(得分:0)
而不是getService尝试getBroadcast:
int c = ungetc(fgetc(f), f); // peek one byte
if (c == EOF) {
...
}
另请查看http://developer.android.com/reference/android/app/PendingIntent.html#getBroadcast(android.content.Context,int,android.content.Intent,int),并找出所需的标记,因为如果只有最后一个警报(在for循环中)我不会感到惊讶将会工作。
