PhoneStateListener表现得很奇怪？

Question

发生的奇怪事情就是当我听到所有三个州时

1. LISTEN_CELL_INFO

2. LISTEN_CELL_LOCATION

3. LISTEN_SIGNAL_STRENGTHS

oncellInfoChanged()和onCellLocationChanged()仅在注册时被调用一次，我只会定期更新onSignalStrengthsChanged()。但是，如果我评论LISTEN_SIGNAL_STRENGTHS，其他两个开始正确获取更新。任何人都可以指出这个问题吗？

public class GSMCellInfoListener {

        TelephonyManager teleManager = null;
        Context mContext;
        GSMCellInfoProvider mGsmCellInfoProvider;

        public GSMCellInfoListener(Context ctx) {
            mContext = ctx;
            mGsmCellInfoProvider = new GSMCellInfoProvider();
        }

        public void addListener() {
            teleManager = (TelephonyManager) mContext
                    .getSystemService(Context.TELEPHONY_SERVICE);
            teleManager.listen(mGsmCellInfoProvider,
                    PhoneStateListener.LISTEN_CELL_INFO);
            teleManager.listen(mGsmCellInfoProvider,
                    PhoneStateListener.LISTEN_CELL_LOCATION);
            teleManager.listen(mGsmCellInfoProvider,
                    PhoneStateListener.LISTEN_SIGNAL_STRENGTHS);
        }

        public void removeListener() {
            teleManager
                    .listen(mGsmCellInfoProvider, PhoneStateListener.LISTEN_NONE);
        }

        public void deleteListener() {
            teleManager = null;
            mGsmCellInfoProvider = null;
        }

        class GSMCellInfoProvider extends PhoneStateListener {
            @Override
            public void onCellInfoChanged(List<CellInfo> cellInfo) {
                super.onCellInfoChanged(cellInfo);
            }

            @Override
            public void onSignalStrengthsChanged(SignalStrength signalStrength) {
                super.onSignalStrengthsChanged(signalStrength);
            }

            @Override
            public void onCellLocationChanged(CellLocation location) {
                super.onCellLocationChanged(location);
            }
        }
    }

您是否曾尝试仅使用一名听众同时注册所有3个活动？在内部，mGsmCellInfoProvider可能位于Map或Set中，因此不允许重复，导致后来的.listen（...）调用覆盖之前的。（/ p>

试试这个：

public void addListener() {
        teleManager = (TelephonyManager) mContext
                .getSystemService(Context.TELEPHONY_SERVICE);
        int listenMask = PhoneStateListener.LISTEN_CELL_INFO +
                         PhoneStateListener.LISTEN_CELL_LOCATION +
                         PhoneStateListener.LISTEN_SIGNAL_STRENGTHS;
        teleManager.listen(mGsmCellInfoProvider,listenMask);
    }
