如何在android中获取手机信号塔的位置

Question

我想找到最近的手机信号塔位置。我试过了

private class ServiceStateHandler extends Handler {
    public void handleMessage(Message msg) {
        switch (msg.what) {
            case MY_NOTIFICATION_ID:
                ServiceState state = mPhoneStateReceiver.getServiceState();
                System.out.println(state.getCid());
                System.out.println(state.getLac());
                System.out.println(mPhoneStateReceiver.getSignalStrength());
                break;
        }
    }
}

我试过这个链接，但它不适合我How to find user location using cell tower?

我认为我做错了什么。因为此链接答案对其他人有用 我做了与链接中所示相同的代码 我正在使用 2,2 google api 创建项目 但我无法获得手机信号塔的位置

查看这个网站，它解释得很好，也很简单：https://www.mylnikov.org/archives/1059

这是一个例子：

.MCC: 268
. MNC: 06
.LAC: 8280
.CELL ID: 5616

API 链接：https://api.mylnikov.org/geolocation/cell?v=1.1&data=open&mcc=268&mnc=06&lac=8280&cellid=5616

希望对你有所帮助。

执行此操作的代码不会等待意图，而是在活动 onCreate 中获取对电话服务的引用，并且在显示时仅在需要时调用 getCellLocation()。

m_manager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);

GsmCellLocation loc = (GsmCellLocation)m_manager.getCellLocation();
if (loc != null)
{
    out.format("Location ");
    if (loc.getCid() == -1) {
        out.format("cid: unknown ");
    } else {
        out.format("cid: %08x ", loc.getCid());
    }
    if (loc.getLac() == -1) {
        out.format("lac: unknown\n");
    } else {
        out.format("lac: %08x\n", loc.getLac());
    }
}

在侦听 PhoneStateService 意图时，我还看到我们必须在 TelephonyManager 上调用 listen 并指定感兴趣的字段。在我的情况下是：

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    Log.d(TAG, "service start");
    m_manager.listen(m_listener, PhoneStateListener.LISTEN_SIGNAL_STRENGTHS | PhoneStateListener.LISTEN_SERVICE_STATE | PhoneStateListener.LISTEN_CALL_STATE);
    return super.onStartCommand(intent, flags, startId);
}

您可能需要将LISTEN_CELL_LOCATION 添加到列表中。

注意：您是否将 ACCESS_COARSE_LOCATION 权限添加到应用清单？如 PhoneStateListener 文档中所述，如果您没有获取信息的权限，某些字段将为空。

试试这个代码 -

mPhoneStateReceiver = new PhoneStateIntentReceiver(this, new ServiceStateHandler());
mPhoneStateReceiver.notifyServiceState(MY_NOTIFICATION_ID);
mPhoneStateReceiver.notifyPhoneCallState(MY_NOTIFICATION_ID);
mPhoneStateReceiver.notifySignalStrength(MY_NOTIFICATION_ID);
mPhoneStateReceiver.registerIntent();

private class ServiceStateHandler extends Handler {
public void handleMessage(Message msg) {
    switch (msg.what) {
        case MY_NOTIFICATION_ID:
            ServiceState state = mPhoneStateReceiver.getServiceState();
            System.out.println(state.getCid());
            System.out.println(state.getLac());
            System.out.println(mPhoneStateReceiver.getSignalStrength());
            break;
    }
}
}
