安全广播LocalBroadcastManager

LocalBroadcastManager是安全的广播，只能在同一个应用中发送和接收。

废话不多说，直接撸码，我这个人就那么直接。

1、注册广播
 MyReceiver receiver = new MyReceiver(); IntentFilter filter = new IntentFilter();  filter.addAction(ConstUtils.ACTION_DO_ACTIVE);  LocalBroadcastManager.getInstance(this).registerReceiver(receiver,filter);

2、定义广播接收器
   private class  MyReceiver extends BroadcastReceiver{        @Override        public void onReceive(Context context, Intent intent) {        //TODO        }    }
3、发送广播
  Intent intent = new Intent();  sellIntent.putExtra("id", id);  sellIntent.setAction(ConstUtils.ACTION_DO_ACTIVE);  LocalBroadcastManager.getInstance(mContext).sendBroadcast(intent);
4、注销广播
LocalBroadcastManager.getInstance(this).unregisterReceiver(receiver);
