我现在用的是清单文件用于创建广播接收器,用于 ACTION_HEADSET_PLUG
。
但我不能得到广播时,耳机连接/断开,
其中许可
我应该清单文件中使用,以便能够接收 ACTION_HEADSET_PLUG
广播意图是什么?
I am using the manifest file for creating broadcast receiver, for ACTION_HEADSET_PLUG
.
But I can't get the broadcast when headset is connect/disconnect,
Which permission
should I use inside the manifest file in order to be able to receive ACTION_HEADSET_PLUG
broadcast intent?
通过API 8,我得到了我的广播接收器叫,而无需创建一个服务或请求额外的权限。
With API 8, I got my broadcast receiver called without creating a service or requesting for extra permissions.
您可以在您的类似,我定义如下的主要活动定义一个内部类
You can define an inner class within your main activity similar to the one I've defined below:
public class HeadSetBroadCastReceiver extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
String action = intent.getAction();
Log.i("Broadcast Receiver", action);
if( (action.compareTo(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
}
}
}
}
于是,无论是动态或静态注册的广播接收器。我动态在我活动的onCreate()方法进行注册矿:
Then, register your broadcast receiver either dynamically or statically. I registered mine dynamically in my Activity's onCreate() method:
this.registerReceiver(headsetReceiver, new IntentFilter(Intent.ACTION_HEADSET_PLUG));
请确保您注销您的BroadcastReceiver与上下文的unregisterReceiver。以我为例,我在的onDestroy()方法,这样做。这应该做到这一点。
Make sure that you unregister your BroadcastReceiver with the Context's unregisterReceiver. In my case, I did this in the onDestroy() method. That should do it.
