这是我的单一通知代码:
myActivity.java
public class myActivity extends Activity {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mylayout);
cal = Calendar.getInstance();
// it is set to 10.30
cal.set(Calendar.HOUR, 10);
cal.set(Calendar.MINUTE, 30);
cal.set(Calendar.SECOND, 0);
long start = cal.getTimeInMillis();
if(cal.before(Calendar.getInstance())) {
start += AlarmManager.INTERVAL_FIFTEEN_MINUTES;
}
Intent mainIntent = new Intent(this, myReceiver.class);
pIntent = PendingIntent.getBroadcast(this, 0, mainIntent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager myAlarm = (AlarmManager)getSystemService(ALARM_SERVICE);
myAlarm.setRepeating(AlarmManager.RTC_WAKEUP, start, AlarmManager.INTERVAL_FIFTEEN_MINUTES, pIntent);
}
}
myReceiver.java
public class myReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context c, Intent i) {
Intent myService1 = new Intent(c, myAlarmService.class);
c.startService(myService1);
}
}
myAlarmService.java
public class myAlarmService extends Service {
@Override
public IBinder onBind(Intent arg0) {
return null;
}
@Override
public void onCreate() {
super.onCreate();
}
@SuppressWarnings("deprecation")
@Override
public void onStart(Intent intent, int startId) {
super.onStart(intent, startId);
displayNotification();
}
@Override
public void onDestroy() {
super.onDestroy();
}
public void displayNotification() {
Intent mainIntent = new Intent(this, myActivity.class);
PendingIntent pIntent = PendingIntent.getActivity(this, 0, mainIntent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationManager nm = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
Notification.Builder builder = new Notification.Builder(this);
builder.setContentIntent(pIntent)
.setAutoCancel(true)
.setSmallIcon(R.drawable.ic_noti)
.setTicker(getString(R.string.notifmsg))
.setContentTitle(getString(R.string.app_name))
.setContentText(getString(R.string.notifmsg));
nm.notify(0, builder.build());
}
}
的AndroidManifest.xml
<uses-permission android:name="android.permission.WAKE_LOCK" />
...
...
...
<service android:name=".myAlarmService" android:enabled="true" />
<receiver android:name=".myReceiver"/>
如果时间尚未过去,一切都会完美无缺。必须出现时会显示通知。
但是如果时间过去(我们假设它是10.31 AM),通知每次都会触发...当我关闭并重新打开应用程序时,当我点击通知时......它有一种非常奇怪的行为
我无法弄清楚它有什么问题。你能帮帮我(并解释为什么,如果你找到解决方案),提前谢谢:)

将显示通知放在if语句中,以便将当前时间与通知设置时间进行比较,如果当前时间在设置时间之前,则显示通知,否则不执行任何操作。
答案 1 :(得分:0)
int temp = calTemp.getTime().compareTo(calendar.getTime());
if(temp > 0){
}else{
alarmManager.set(AlarmManager.RTC, calendar.getTimeInMillis(),
pendingIntent1);
}
这里calTemp
给出了当前时间,calender
给出了我想要发出警报的时间。因此,根据上面的代码,如果时间已经过去,那么notification
将无法确定。

您好我有same problem and found a solution in this SO post,基本上我的想法是依赖AlarmManager,Receiver但避免使用服务。
由于您使用服务只是为了构建和显示通知,您可能会发现我的方法很有用。
让我知道。
