检索额外意图时出现问题

Question

我有以下一次性警报代码...

        public boolean onMenuItemClick(MenuItem item) {
            Intent intent = new Intent(CalendarViewActivity.this, OneShotAlarm.class);
            Bundle bun = new Bundle();
            bun.putString("data", "hello this is my message...");
            intent.putExtras(bun);
            PendingIntent sender = PendingIntent.getBroadcast(CalendarViewActivity.this,
                    0, intent, 0);

            // We want the alarm to go off 5 seconds from now. TODO
            Calendar calendar = Calendar.getInstance();
            calendar.setTimeInMillis(System.currentTimeMillis());
            calendar.add(Calendar.SECOND, 5);

            // Schedule the alarm!
            AlarmManager am = (AlarmManager)getSystemService(ALARM_SERVICE);
            am.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), sender);
            return false;
        }
    });
}



public class OneShotAlarm extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    // TODO
    Toast.makeText(context, "Alarm! " + intent.getExtras().getString("data"), Toast.LENGTH_SHORT).show();
}

}

警报正确响起，但由于某种原因未检索“数据”额外内容，并且被设置为空。

感谢您的帮助！

Answer 1

尝试：

Intent intent = new Intent(CalendarViewActivity.this, OneShotAlarm.class);
intent.putExtra("data", "hello this is my message...");
PendingIntent sender = PendingIntent.getBroadcast(CalendarViewActivity.this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

Answer 2

可能重复 getExtra from Intent launch from aendingIntent

如果没有的话如果没有帮助，请告诉我们更多有关您的文件的信息（您需要有一个设置闹钟的活动、启动服务的广播接收器以及告诉应用程序做什么的服务当闹钟响起时）

Answer 3

putExtra 函数的文档引用：

name 额外数据的名称，带有包前缀。

不会是这个原因吧？
