java - 如何在 Android Studio 中更改已弃用的代码

Question

我有一个代码来检查用户是否已连接

val connected:Boolean
        val connectivityManager = getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
        connected = connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_VPN).state == NetworkInfo.State.CONNECTED

if(connected){
   
} else {
}

但每次我构建它时，它都会告诉我它已折旧。

如果有其他方法可以检查用户连接更改，请分享。

来自 Android 文档:

This method was deprecated in API level 23. This method does not support multiple connected networks of the same type. Use getAllNetworks() and getNetworkInfo(android.net.Network) instead.

在你的情况下你可能真的想要:

Network network = connectivityManager.getActiveNetwork();
NetworkCapabilities caps = connectivityManager.getNetworkCapabilities(network);
connected = caps.hasCapability(TRANSPORT_VPN) && network.isConnected();
