private BroadcastReceiver connectionListener = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            NetworkInfo networkInfo = ((ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE)).getActiveNetworkInfo();
            if ((networkInfo != null && networkInfo.getType() == ConnectivityManager.TYPE_WIFI) & (networkInfo.isConnected())){
                sendBroadcastMessage(getString(R.string.FORCED_NETWORK_CONNECTION_ESTABLISHED));
                Log.w(LOG, "wifi connection established");
            }
            else{
                sendBroadcastMessage(getString(R.string.FORCED_NETWORK_CONNECTION_LOST));
                Log.e(LOG, "no wifi connection");
            }
        }
    };

registerReceiver(connectionListener, new IntentFilter("android.net.conn.CONNECTIVITY_CHANGE"));

第3。取决于您需要添加权限：

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

互联网重新连接后，将http发送请求发送到服务器
