Android 棒棒糖坏了WiFi连接，退到移动网络，如何切换到WiFi？

汤姆， 我有类似的问题，你有，但不能解决它的方式，你和其他人建议。我的onAvailable回拨从未为未连接互联网的WiFi接通。这是我的密码 @塔吉塔皮（21） 公共静态无效连接到FifiNetworkSynchronousAPI21（最终接线配置接线配置）{ NetworkRequest.Builder=新建NetworkRequest.Builder（）

汤姆是谁？你忘了把链接附加到另一个问题上吗？

    builder.addTransportType(NetworkCapabilities.TRANSPORT_WIFI);
    builder.removeCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET);

    builder.setNetworkSpecifier(wifiConfig.SSID);
    NetworkRequest request = builder.build();

    ConnectivityManager cm = (ConnectivityManager)App.getApp().getSystemService(Context.CONNECTIVITY_SERVICE);
    cm.requestNetwork(request,new ConnectivityManager.NetworkCallback() {

        @Override

            // TODO Auto-generated method stub

            super.onAvailable(network);
        }
