Question

我想找到最近的蜂窝塔位置。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，但它不适用于我How to find user location using cell tower?

我认为我做错了什么。因为这个链接答案正在为其他人工作我做了链接中显示的相同代码我使用2,2谷歌API来创建项目但我无法获得手机信号塔的位置

Answer 1

我执行此操作的代码不等待意图，但在活动onCreate中提取对电话服务的引用，并在需要时显示只调用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，我也看到我们必须在TelephonyManager上调用listen并指定感兴趣的字段。就我而言：

@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：您是否已将ACCESS_COARSE_LOCATION权限添加到应用清单？如PhoneStateListener文档中所述，如果您没有信息权限，某些字段将为空。

查看此网站，它解释得非常简单：https://www.mylnikov.org/archives/1059

以下是一个例子：

model_dummy <- nls(y ~ (asym+ asym.L1 * is.L1 + asym.l2*is.L2) / 
(1 + exp( -slope * (x – (x0 + x0.L1 * is.L1 + x0.L2 * is.L2) ) ) ), 
start = c(…), data = my_data)

希望它对你有所帮助。

尝试使用代码 -

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;
    }
}
}
