我有这个问题:我将alarmManager设置为intent和pendingintent,如果满足某些条件,在intent中添加一些额外的东西。问题是我的接收器没有读取我的附加内容:
在 MainActivity 中设置 alarmManager:
AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent i = new Intent(MainActivity.this, AlarmReceiver.class);
PendingIntent pi = PendingIntent.getBroadcast(MainActivity.this , 0, i, PendingIntent.FLAG_ONE_SHOT);
// conditions
i.putExtra("type", 1);
i.putExtra("mealType", 2);
Log.d(TAG , "type: " + i.getExtras().getInt("type"));
Log.d(TAG , "mealtype: " + i.getExtras().getInt("mealType"));
calendar.set(calendar.HOUR_OF_DAY, 7);
am.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pi);
在logcat中我可以看到:
D/MAIN: type: 1
D/MAIN: mealtype: 2
但在我的接收器中:
public void onReceive(Context context, Intent intent) {
/**
* Receiver
*/
Log.d(TAG, "Allarme ricevuto dal receiver");
int type = intent.getExtras().getInt("type");
Log.d(TAG , "type: " + type);
Log.d(TAG , "mealtype: " + intent.getExtras().getInt("mealType"));
Log.d(TAG , "unExisted: " + intent.getExtras().getInt("unExisted"));
if(type == 0){
Intent service = new Intent(context, AlarmService.class);
service.putExtra("type", type);
context.startService(service);
}
if(type == 1){
int mealType = intent.getExtras().getInt("mealType");
Intent service1 = new Intent(context, AlarmService.class);
service1.putExtra("type", type);
service1.putExtra("mealType", mealType);
context.startService(service1);
}
}
我看到这个:
D/ALARM RECEIVER: Allarme ricevuto dal receiver
D/ALARM RECEIVER: type: 0
D/ALARM RECEIVER: mealtype: 0
D/ALARM RECEIVER: unExisted: 0
我将 all'key 视为 0,也将其视为 0“unExistest”,我从未在意图中插入此密钥。为什么?
