try{
ConnectivityManager connectivityManager =(ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
Method setMobileDataEnable = connectivityManager.getClass().getDeclaredMethod("setMobileDataEnabled",boolean.class);
setMobileDataEnable.invoke(connectivityManager,false);//这里true为打开网络,false为关闭网络
