如何检查Wi-Fi p2p是否已连接？

在我的应用程序中，我需要检查 p2p 是否已连接。以前我使用以下代码对其进行归档，但 NetworkInfo 已弃用，所以我想以另一种方式实现它。

mWifiP2pManager.requestNetworkInfo(mChannel, new NetworkInfoListener() {
        @Override
        public void onNetworkInfoAvailable(NetworkInfo networkInfo) {
            mIsP2pConnected = networkInfo.isConnected();
        }
    });

我尝试使用以下代码来获取 p2p 的状态。但是当我通过 Wi-Fi Direct 连接其他设备时，我找不到此日志。但是，如果我将addCapability的参数设置为NetworkCapabilities.NET_CAPABILITY_INTERNET并打开wifi，我可以找到此日志。

        mCM = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkRequest networkRequest =
                new NetworkRequest.Builder().addCapability(NetworkCapabilities.NET_CAPABILITY_WIFI_P2P).build();
        mCallback = new ConnectivityManager.NetworkCallback() {
            @Override
            public void onAvailable(@NonNull Network network) {
                super.onAvailable(network);
                Log.d("MainActivity", "onAvailable: Detect network");

            }
        };
       mCM.registerNetworkCallback(networkRequest, mCallback);

In my app, I need to check if p2p is connected. Previously I use following code to archive it, but NetworkInfo is deprecated, so I want to implement it in another way.

mWifiP2pManager.requestNetworkInfo(mChannel, new NetworkInfoListener() {
        @Override
        public void onNetworkInfoAvailable(NetworkInfo networkInfo) {
            mIsP2pConnected = networkInfo.isConnected();
        }
    });

I tried to use following code to get the status of p2p. But when I connect other device via Wi-Fi Direct, I can't find this log.
However, if I set the parameter of addCapability is NetworkCapabilities.NET_CAPABILITY_INTERNET and turn on wifi, I can find this log.

        mCM = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkRequest networkRequest =
                new NetworkRequest.Builder().addCapability(NetworkCapabilities.NET_CAPABILITY_WIFI_P2P).build();
        mCallback = new ConnectivityManager.NetworkCallback() {
            @Override
            public void onAvailable(@NonNull Network network) {
                super.onAvailable(network);
                Log.d("MainActivity", "onAvailable: Detect network");

            }
        };
       mCM.registerNetworkCallback(networkRequest, mCallback);

尝试添加 WIFI 传输类型以及添加 WIFI_P2P 功能：

...
NetworkRequest.Builder builder = new NetworkRequest.Builder();
builder.addTransportType(NetworkCapabilities.TRANSPORT_WIFI);
builder.addCapability(NetworkCapabilities.NET_CAPABILITY_WIFI_P2P);
NetworkRequest networkRequest = builder.build();
...

Try to add WIFI transport type along with adding WIFI_P2P capability:

...
NetworkRequest.Builder builder = new NetworkRequest.Builder();
builder.addTransportType(NetworkCapabilities.TRANSPORT_WIFI);
builder.addCapability(NetworkCapabilities.NET_CAPABILITY_WIFI_P2P);
NetworkRequest networkRequest = builder.build();
...
