Android的简单的广播的例子

简单的广播的代码，备忘！

1、发送广播

Intent mIntent = new Intent("com.abc.abcd");sendBroadcast(mIntent);

2、注册广播

 IntentFilter filter = new IntentFilter("com.abc.abcd"); registerReceiver(broadcastReceiver, filter);

3、接收广播

 BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {        @Override        public void onReceive(Context context, Intent intent) {            //处理接收到广播之后的事件        }    };

4、退出后的注销

  @Override    public void onDestroy() {        super.onDestroy();        unregisterReceiver(broadcastReceiver);// 注销广播    }
