Android -- BroadCastReceiver的簡單使用

標籤：

//首先建立一個繼承自BroadcastReceiver的廣播監聽類class StartActiviryReceiver extends BroadcastReceiver {        public final static String intentKey = "startTestActivity";        @Override        public void onReceive(Context context, Intent intent) {            Intent t = new Intent(MyActivity.this, TestActivity.class);            startActivity(t);        }    }

//注冊private StartActiviryReceiver startActiviryReceiver;@Override    protected void onResume() {        super.onResume();        //注冊監聽廣播        startActiviryReceiver = new StartActiviryReceiver();        registerReceiver(startActiviryReceiver, new IntentFilter(startActiviryReceiver.intentKey));    }

在完畢某件事之後，進行廣播通知

Intent intent = new Intent(StartActiviryReceiver.intentKey);sendBroadcast(intent);
