Question

我正在尝试获取以下数据：

基站：CellID和RSS（识别哪一个是基站）
适用于所有neigbouring站：CellID和RSS

有各种API，看起来我必须使用不同的API telephonyManager和PhoneStateListener。我有点困惑，因为我认为这应该在一个界面中可用。此外，我认为应该可以轮询当前基站的CellID，而不必监听状态变化以确定int，因为也可以从telephonyManager轮询邻近单元站cal。

你能告诉我如何获得上面指定的数据吗？

新的skool-way：API 17更好更清洁，但仍然太新。

List<CellInfo> cellInfos = (List<CellInfo>) this.telephonyManager.getAllCellInfo();

for(CellInfo cellInfo : cellInfos)
{
    CellInfoGsm cellInfoGsm = (CellInfoGsm) cellInfo;

    CellIdentityGsm cellIdentity = cellInfoGsm.getCellIdentity();
    CellSignalStrengthGsm cellSignalStrengthGsm = cellInfoGsm.getCellSignalStrength();

    Log.d("cell", "registered: "+cellInfoGsm.isRegistered());
    Log.d("cell", cellIdentity.toString());         
    Log.d("cell", cellSignalStrengthGsm.toString());
}

旧API无法提供非常令人满意的解决方案。但这是一个古老的方式：

this.telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
this.phoneStateListener = setupPhoneStateListener();
this.telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_CELL_LOCATION);
this.telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_DATA_CONNECTION_STATE);
this.telephonyManager.listen(phoneStateListener, PhoneStateListener.LISTEN_SIGNAL_STRENGTHS);

// This part is used to listen for properties of the neighboring cells
List<NeighboringCellInfo> neighboringCellInfos = this.telephonyManager.getNeighboringCellInfo();
for(NeighboringCellInfo neighboringCellInfo : neighboringCellInfos)
{
    neighboringCellInfo.getCid();
    neighboringCellInfo.getLac();
    neighboringCellInfo.getPsc();
    neighboringCellInfo.getNetworkType();
    neighboringCellInfo.getRssi();

    Log.d("cellp",neighboringCellInfo.toString());
}

public PhoneStateListener setupPhoneStateListener()
{
    return new PhoneStateListener() {

        /** Callback invoked when device cell location changes. */
        @SuppressLint("NewApi")
        public void onCellLocationChanged(CellLocation location)
        {
            GsmCellLocation gsmCellLocation = (GsmCellLocation) location;
            gsmCellLocation.getCid();
            gsmCellLocation.getLac();
            gsmCellLocation.getPsc();

            Log.d("cellp", "registered: "+gsmCellLocation.toString());
        }

        /** invoked when data connection state changes (only way to get the network type) */
        public void onDataConnectionStateChanged(int state, int networkType)
        {
            Log.d("cellp", "registered: "+networkType);
        }

        /** Callback invoked when network signal strengths changes. */
        public void onSignalStrengthsChanged(SignalStrength signalStrength)
        {
            Log.d("cellp", "registered: "+signalStrength.getGsmSignalStrength());
        }

    };
}

不要忘记设置所有必要的权限这个解决方案的问题是，我没有得到任何相邻的单元格信息，尽管我设置了：

uses-permission android：name =“android.permission.ACCESS_COARSE_UPDATES”

（请注意，我使用的是三星手机，这是三星手机不支持相邻手机列表的已知问题）

Android：获取基站和邻居小区的Cell ID和RSS
