android动态注册广播接收器

简单一段代码足以说明： 

if(value!="close"){IntentFilter filter = new IntentFilter();filter.addAction("android.intent.action.NEW_OUTGOING_CALL");//注明要注册接收哪种广播filter.setPriority(Integer.MAX_VALUE);//设置优先级context.registerReceiver(myReceiver, filter);//注册phoner();}else if(value=="close"){context.unregisterReceiver(myReceiver);//注销}
