从活动到的BroadcastReceiver Android的传球数据显示空

问题描述

限时删除！！

我有它使用一个AlarmManager调用一个BroadcastReceiver在特定时间点的活动。这一切工作正常，只是当我尝试一些额外的字符串调用的BroadcastReceiver时，增加的意图，他们总是拿出另一端为空。

I've got an activity which uses an AlarmManager to call a BroadcastReceiver at a particular point in time. This all works fine, except when I try to add some extra strings to the intent when calling the BroadcastReceiver, they always come up as null on the other end.

活动code：

    Intent intent = new Intent(this, ScheduleReceiver.class);
    intent.putExtra("testString", "I'm a string");
    PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 999, intent, 0);

    AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
    alarmManager.set(AlarmManager.RTC, System.currentTimeMillis(), pendingIntent);

BroadcastReceiver的code

BroadcastReceiver code

 public void onReceive(Context context, Intent intent) {
      Log.v(TAG, "TestString: " + intent.getStringExtra("testString"));
 }

的TestString的内容总是空中的BroadcastReceiver，我究竟做错了什么？

The content of 'teststring' is always null in the BroadcastReceiver, what am I doing wrong?

推荐答案

试着用得到它：

intent.getExtras().get("testString");
