廣播代碼

    class myboad extends BroadcastReceiver {        @Override        public void onReceive(Context context, Intent intent) {            System.out.println("收到廣播。。。");            jieXi();        }    }

動態註冊廣播

private myboad b;private IntentFilter intentFilter;intentFilter = new IntentFilter();intentFilter.addAction("com.hnjd");if (isChecked) {                    System.out.println("狀態開啟");                    Intent intent = new Intent(MainActivity.this, lightService.class);                    startService(intent);                    registerReceiver(b, intentFilter);                } else {                    System.out.println("狀態關閉");                    unregisterReceiver(b);                    Intent intent = new Intent(MainActivity.this, lightService.class);                    stopService(intent);                }
