1 需求
通过用户名和密码连接指定wifi热点，网上的代码乱七八糟，没几个可以用，我这边整理了下，测试了华为Android9.0和小米Android9.0和10.0和OPPO Android9.0 都没问题，直接回调结果就行。
2 问题
在Android10.0手机上
mWifiManager.addNetwork(wifiNewConfiguration);
返回-1
说明不能用这种方式了，
android Q或者更高的版本，这个方法始终返回-1，去看下官网：Android 10 的新方案如下连接：https://developer.android.google.cn/guide/topics/connectivity/wifi-bootstrap

// do failure processing here..

}
};
connectivityManager.requestNetwork(request, networkCallback);
}
}
connectWifiApByName函数只针对小于等于android 9.0，不能兼容android 10.0,所以connectWifiApByNameAndPwd这个函数支持所有版本类型
调用如下
WifiApUtil.connectWifiApByNameAndPwd(this, name, password, object : WifiApUtil.CallBack {
override fun connnectResult(connectResult: Boolean) {
Log.i(TAG, "connectResult is:" + connectResult)
}
});//
4 需要注意的地方
Andorid 10.0连接指定热点，需要先把wifi需要打开，不然没反应，没有回调，我们上面的代码在Android9.0以下连接指定热点之前，我们是通过下面的函数打开wifi
if (!mWifiManager.isWifiEnabled()) {
mWifiManager.setWifiEnabled(true);
}
在10.版本，isWifiEnabled()这个函数是生效的，但是setWifiEnabled(true)这个函数是失败的，没有效果，我们如果发现没有打开wifi，我们可以再连接之前进行引导用户打开，我们可以跳到设置面板提示用户启用和禁用 Wi-Fi
startActivity(Intent(Settings.Panel.ACTION_INTERNET_CONNECTIVITY))
