前言

　　此博客建设中，待后续完善。。。。

监听网络状态

        ConnectivityManager connectivity = (ConnectivityManager) getContext().getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkRequest.Builder builder = new NetworkRequest.Builder();
        NetworkRequest request = builder.addCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET)
                .addTransportType(NetworkCapabilities.TRANSPORT_WIFI)
                .addTransportType(NetworkCapabilities.TRANSPORT_CELLULAR)
                .build();
        connectivity.registerNetworkCallback(request, new ConnectivityManager.NetworkCallback(){
            @Override
            public void onAvailable(Network network) {
                super.onAvailable(network);
                
            }
        });
