Android 獲得網路連線狀態

網路連線狀態改變時接收通知

BroadcastReceiver mReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if(ConnectivityManager.CONNECTIVITY_ACTION.equals(action)) {
            boolean noConnectivity = intent.getBooleanExtra(ConnectivityManager.EXTRA_NO_CONNECTIVITY, false);
            NetworkInfo networkInfo = (NetworkInfo)intent.getParcelableExtra(ConnectivityManager.EXTRA_NETWORK_INFO);
            boolean mobileNetwork = (networkInfo.getType()==ConnectivityManager.TYPE_MOBILE);
        }
    }
}

IntentFilter filter = new IntentFilter();
filter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
context.registerReceiver(mReceiver, filter);
