我在一个应用程序的工作inwhich我使用 AlarmManager 调度的事情。我的闹钟设置。但这个报警不会调用广播接收器写入捕捉事件。我寻觅了很多，但我没有发现任何东西，解决了问题。我张贴我的code，请看看，看看，如果我失去了一些东西。

I am working on an application inwhich I am using AlarmManager for scheduling things. My Alarm is set. But this Alarm does not invoke BroadcastReceiver written to catch the event. I have searched a great deal but I have not found anything that solves the issue. I am posting my code, please have a look and see if I am missing something.

AlarmManagerClass：

public class ScheduleMessageManager { Context context; PendingIntent sender; AlarmManager am; public ScheduleMessageManager(Context context) { this.context = context; } public void addAlram(int scheduledMessageID, long scheduledTime) { // Activate Broadcast Receiver to receive broadcasts activateBroadcastReceiver(); //Calendar cal = Calendar.getInstance(); Intent intent = new Intent(context, AlarmReceiver.class); // In reality, you would want to have a unique variable for the request // code intent.putExtra("scheduledMessageID", scheduledMessageID); sender = PendingIntent.getBroadcast(context, scheduledMessageID, intent, PendingIntent.FLAG_UPDATE_CURRENT); // Get the AlarmManager service am = (AlarmManager) context.getSystemService(context.ALARM_SERVICE); am.set(AlarmManager.RTC_WAKEUP, scheduledTime, sender); Log.e("In ScheduleMessageManage", "***** Alarm is set to the mmessage *****"); } public void cancelPeriodicSchedule(PendingIntent sender) { if (am != null) { if (sender != null) { am.cancel(sender); sender.cancel(); } } // Deactivate Broadcast Receiver to stop receiving broadcasts deactivateBroadcastreceiver(); } private void activateBroadcastReceiver() { PackageManager pm = context.getPackageManager(); ComponentName componentName = new ComponentName(context, AlarmReceiver.class); pm.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP); Toast.makeText(context, "activated", Toast.LENGTH_LONG).show(); } private void deactivateBroadcastreceiver() { // TODO Auto-generated method stub PackageManager pm = context.getPackageManager(); ComponentName componentName = new ComponentName(context, AlarmReceiver.class); pm.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP); Toast.makeText(context, "cancelled", Toast.LENGTH_LONG).show(); }

}

我的AlarmReceiver：

public class AlarmReceiver extends BroadcastReceiver { int pendingIntentID; // same as scheduledMessageID @Override public void onReceive(Context context, Intent intent) { Log.e("In On Receive", "Alarm has Initiated Broadcast Receiver...."); if (intent.hasExtra("scheduledMessageID")) { pendingIntentID = intent.getExtras().getInt("scheduledMessageID"); Intent sendMessageServiceIntent = new Intent(context, SendMessageService.class); sendMessageServiceIntent.putExtra("pendingIntentID", pendingIntentID); context.startService(sendMessageServiceIntent); } }

}

OnReceieve（）永远不会被调用。

在我的的Manifest.xml

<receiver android:name="myPackage.AlarmReceiver" android:enabled="true" > </receiver>

我无法找出请问问题出。请大家帮我出了。谢谢！

I am unable to figure out the does the problem lie. Please help me out of it. Thanks.!

推荐答案

在使用广播接收器的一种很好的教程中的 www.vogella/articles/AndroidBroadcastReceiver/article.html 。从本质上讲，你的接收机不声明它会收到什么样的事件。在清单文件中声明需要的是这样的：

A good tutorial on using Broadcast receivers is given in www.vogella/articles/AndroidBroadcastReceiver/article.html. In essence, your receiver doesn't declare what events it will receive. The declaration in the Manifest file needs something like:

<receiver android:name="myPackage.AlarmReceiver" android:enabled="true" > <intent-filter> <action android:name="yourpany.blah.mybroadcast" /> </intent-filter> </receiver>

当你创建的意图，它需要

And when you create the intent, it needs

Intent intent = new Intent(); intent.setAction("yourpany.blah.mybroadcast"); // All the other things you want to put in the intent
