你好我的工作产生过当耳机从手机中删除的事件的应用程序。 我创建了一个广播接收器与接收方法

Hi i am working on an application that generate an event when ever the headphone is removed from the mobile phone. I have created a broadcast receiver with receive method as

public void onReceive(Context context, Intent intent) { // TODO Auto-generated method stub String action = intent.getAction(); Log.i("Broadcast Receiver", "Hello"); if( (actionpareTo(Intent.ACTION_HEADSET_PLUG)) == 0) //if the action match a headset one { int headSetState = intent.getIntExtra("state", 0); //get the headset state property int hasMicrophone = intent.getIntExtra("microphone", 0);//get the headset microphone property if( (headSetState == 0) && (hasMicrophone == 0)) //headset was unplugged & has no microphone { //do whatever } } }

调用此方法如下：

Calling this method as follows

IntentFilter receiverFilter = new IntentFilter(Intent.ACTION_HEADSET_PLUG); HeadSetBroadCastReceiver receiver = new HeadSetBroadCastReceiver(); registerReceiver( receiver, receiverFilter );

另外我有登记本中表现为

also i have register this in manifest as

<receiver android:name=".HeadsetBroadCastReceiver"> <intent-filter> <action android:name="android.intent.action.ACTION_HEADSET_PLUG"/> </intent-filter> </receiver>

和许可

但是，这不列入工程任何人都可以指导我通过这个？

But this doesnot works can anyone guide me through this?

推荐答案

这里的问题是，这个braodcast具有标志 Intent.FLAG_RECEIVER_REGISTERED_ONLY设定。这意味着清单recivers不会赶上这一点。 Here是一个完整的explenation。

Problem here is that this braodcast has flag Intent.FLAG_RECEIVER_REGISTERED_ONLY set. This means that manifest recivers will not catch that. Here is a full explenation.
