android Broadcast广播消息代码实现

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。
