Question

我希望在未连接wifi的一段时间后关闭我的wifi。我遇到的问题是当我删除wifi连接时 onreceive接到电话，但说网络仍然连接。我不明白为什么它的连接没有状态只是改变？国家改变得如此之快以至于没有时间去抓住它吗？任何帮助将不胜感激。

这是我的接收器

class WifiDataReceiver extends BroadcastReceiver {
    public void onReceive(Context c, Intent intent) {
        Log.v("msg", "onReceive WifiDataReceiver");
        Log.v("msg", "mWifi : " + mWifi);
        cm = (ConnectivityManager) c.getSystemService(Context.CONNECTIVITY_SERVICE);
        mWifi = cm.getNetworkInfo(1).getState();
        if (mWifi != NetworkInfo.State.CONNECTED){
            try {
                Thread.sleep(disconnectionTimeout);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            wifiManager.setWifiEnabled(false);
            Log.v("msg", "Disconnect  WifiDataReceiver");

        } else {
            Log.v("msg", "connected");
        }
    }

我已在2台设备（GS3和Samsung Charge）上测试了您的代码。它工作正常。切换wifi设置后，状态发生了变化。我的代码在github上，here。以下是日志：

我认为这可能与您的手机或ROM有关。
