android:cellid和lac不起作用

Question

我正在制作一个应用程序，其中我必须获得乳胶和细胞id。我正在使用

private PhoneStateIntentReceiver mPhoneStateReceiver;
ServiceState state = mPhoneStateReceiver.getServiceState();

 int cid = state.getCid();
 int lac = state.getLac();

它给出的错误是PhoneStateIntentReceiver不能解析为类型，而getcellid和getlac也给出错误，即ServiceState没有定义getcellid

任何帮助都将不胜感激。

Answer 1

使用它来获取cid和Lac

 final TelephonyManager telephony = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
if (telephony.getPhoneType() == TelephonyManager.PHONE_TYPE_GSM) {
    final GsmCellLocation location = (GsmCellLocation) telephony.getCellLocation();
    if (location != null) {
        msg.setText("LAC: " + location.getLac() + " CID: " + location.getCid());
    }
}
