在BlueStacks 5模拟器中，ConnectivityManager回调可能不会起作用，因此需要将其重写以确保其正常工作。以下是一个代码示例，说明如何重写ConnectivityCallback类以使用BlueStacks 5中的ConnectivityManager：

import android.content.Context; import android.net.ConnectivityManager; import android.net.Network; import android.net.NetworkCapabilities; import android.net.NetworkRequest; import android.os.Handler;

public class BlueStacksConnectivityCallback extends ConnectivityManager.NetworkCallback {

private Handler mHandler;
private Context mContext;

public BlueStacksConnectivityCallback(Context context, Handler handler) {
    mHandler = handler;
    mContext = context;
}

@Override
public void onAvailable(Network network) {
    super.onAvailable(network);

    // Get current network capabilities
    ConnectivityManager cm = (ConnectivityManager) mContext.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkCapabilities nc = cm.getNetworkCapabilities(network);

    // Check if network is connected and has Internet access
    if (nc.hasCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET)) {
        mHandler.post(new Runnable() {
            @Override
            public void run() {
                // Connectivity is available
                // Do your work here
            }
        });
    }
}

@Override
public void onLost(Network network) {
    super.onLost(network);

    mHandler.post(new Runnable() {
        @Override
        public void run() {
            // Connectivity is lost
            // Do your work here
        }
    });
}

}

使用此重写类时，可以将其作为参数传递给ConnectivityManager.registerNetworkCallback()方法。例如：

ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); NetworkRequest.Builder builder = new NetworkRequest.Builder(); builder.addCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET); NetworkRequest request = builder.build(); BlueStacksConnectivityCallback callback = new BlueStacksConnectivityCallback(this, mHandler); cm.registerNetworkCallback(request, callback);

这将确保您的ConnectivityManager回调在BlueStacks 5模拟器中正常工作。
