警报没有重复

Question

这是我触发警报的代码

public void startAlarmp(){
    int hour=10;
    int minute=30;
    Intent alarmIntent2 = new Intent(getApplicationContext(), AlarmReceiver.class);
    pendingIntentp = PendingIntent.getBroadcast(getApplicationContext(), 234324243, alarmIntent2, 0);
    alertmanagerp = (AlarmManager)getSystemService(ALARM_SERVICE);
    alertmanagerp.setRepeating(AlarmManager.RTC_WAKEUP,c1.getTimeInMillis(),24*60*60*1000,pendingIntentp);
}

这是我的AlarmReceiver.java 代码

public class AlarmReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
    //my stuff
}

它只会第一次触发之后就不再重复

并在重复时出现以下错误

D/ActivityThread: setTargetHeapUtilization:0.25
D/ActivityThread: setTargetHeapIdealFree:8388608
D/ActivityThread: setTargetHeapConcurrentStart:2097152

Answer 1

您正在将挂起意图的标志设置为0。尝试将其更改为FLAG_UPDATE_CURRENT。

pendingIntentp = PendingIntent.getBroadcast(getApplicationContext(), 234324243, alarmIntent2, PendingIntent.FLAG_UPDATE_CURRENT);

编辑。试试这个：

public void startAlarmp(){
    int hour=10;
    int minute=30;
    Intent alarmIntent2 = new Intent(YourActivity.this, AlarmReceiver.class);
    pendingIntentp = PendingIntent.getBroadcast(YourActivity.this, 0, alarmIntent2, 0);
    alertmanagerp = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
    alertmanagerp.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 2*60*1000,pendingIntentp);
}
