如何在Android7和更高版本中使用PhoneStateListener获取网络类型的更新？

import android.telephony.PhoneStateListener;
import android.telephony.ServiceState;
import android.util.Log;

public class MyPhoneStateListener extends PhoneStateListener {
    @Override
    public void onServiceStateChanged(ServiceState serviceState) {
        super.onServiceStateChanged(serviceState);
        int networkType = serviceState.getDataNetworkType();
        Log.d("Network Type", "Network Type: " + networkType);
        // 在这里可以根据networkType进行相应的处理
    }
}

import android.content.Context;
import android.telephony.TelephonyManager;

public class MainActivity extends AppCompatActivity {
    private TelephonyManager telephonyManager;
    private MyPhoneStateListener phoneStateListener;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
        phoneStateListener = new MyPhoneStateListener();
        telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_SERVICE_STATE);
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_NONE);
    }
}
