安卓:得到的CellID和RSS用于基站和Neigboring细胞(Android: get Cel

2019-08-17 21:35发布

我试图得到以下数据:

  • 基站:的CellID和RSS(识别哪一个是基站)
  • 对于所有neigbouring站:的CellID和RSS

有各种各样的API,它看起来像我不得不使用不同的API telephonyManager和PhoneStateListener。 我是一个littlebit困惑,因为我认为这应该在一个界面中提供。 此外,我认为它应该是可能的查询,而不必听国家的变化来判断int当前基站的CellID,因为周围基站CAL也可以从telephonyManager调查。

你能告诉我怎样才能得到上述规定的数据?

Answer 1:

新斯库尔路:API 17更漂亮和更清洁,但还是太新。

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());
}

旧的API并没有提供一个非常令人满意的解决方案。 但这里的老斯库尔方式:

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());
        }

    };
}
  • 不要忘了所有必须的权限,这种解决方案的问题是,我没有得到任何相邻小区信息沉绵我的设置:

    使用许可权的android:NAME = “android.permission.ACCESS_COARSE_UPDATES”

(请注意,我用的是三星手机,这是一个已知的问题,三星手机不支持相邻小区的列表)
