我用的是Fragment ， 发送写在一个类中，接收写在另外一个类的内部类中。代码动态实现注册。

代码：

 

myReceiver =  new zcd.netanything.MyCar.myReceiver();              IntentFilter filter = new IntentFilter();              //向过滤器中添加action              filter.addAction("zcd.netanything");              //注册广播               getActivity().registerReceiver(myReceiver, filter);                             //broadcast             Intent intent=new Intent();            intent.putExtra("wifiurl",wifiurl.getText().toString());            intent.putExtra("wificom",wificom.getText().toString());             intent.putExtra("wificamera",wificamera.getText().toString());            intent.setAction("zcd.netanything");            getActivity().sendBroadcast(intent);

内部类：

 

//内部类  广播接收       public static  class myReceiver extends BroadcastReceiver {           @Override          public void onReceive(Context context, Intent intent) {                     // TODO Auto-generated method stub                     wifiurl = intent.getStringExtra("wifiurl");                       wificom = intent.getStringExtra("wificom");                       wificamera = intent.getStringExtra("wificamera");                        Toast.makeText(context, "广播已经接收", Toast.LENGTH_SHORT).show();               }          }

 

这样就可以了。
