在我的应用程序中,我想将AlarmManager设置为特定时间:2016-11-15 13:00:00
。然后显示通知(或吐司)而不重复它然后关闭。但我的代码不起作用。
MainActivity :
Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(System.currentTimeMillis());
cal.clear();
cal.set(2016, 11, 15, 13, 00);
AlarmManager alarmMgr = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(this, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);
alarmMgr.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);
AlarmReceiver :
public class AlarmReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Utils.toast("dddddd", context);
Log.e("alarm!!!!!! ", " fire");
}
}
清单:
<uses-permission android:name="android.permission.WAKE_LOCK"/>
<receiver android:name=".Views.AlarmReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
<action android:name="android.intent.action.QUICKBOOT_POWERON"/>
</intent-filter>
</receiver>
此代码有什么问题,为什么alarm manager
没有显示toast
或Log
?
