Question

我试图在我的应用中实施通知。

我使用带有一些Extras（模型对象）的意图的PendingIntent的AlarmManager但是，当我在BroadcastReceiver类中接收时，我的所有额外内容都消失了

这里是代码： MainActivity

private void saveNotification(Task t) {
    Intent intent = new Intent(this, MyAlarmBroadcastReceiver.class);
    intent.putExtra("title", t.getTitle()); //not null object
    intent.putExtra("text", t.getText()); //not null object
    // intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP); - I tried, but it didn't work
    PendingIntent pendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), 12345678, intent,PendingIntent.FLAG_UPDATE_CURRENT);
    AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
    alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (5 * 1000), pendingIntent);
    Toast.makeText(this, "seting the notification in 5 seconds", Toast.LENGTH_SHORT).show();
}

MyAlarmBroadcastReceiver：

public class MyAlarmBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Bundle bundle = intent.getExtras(); 
        String taskTitle = bundle.getString("title"); //null here
        String taskText = bundle.getString("text"); // also null here
        startNotification(context, taskTitle , taskText);
    }
}

我的猜测是onReceive方法中收到的意图可能不是saveNotification方法中发出的原始意图，但我没有想法如何获取原始意图。

提前致谢

PendingIntent with Extras返回null
