如何只显示信标的时间戳，rssi和mac-address

Question

private final ThreadLocal<ScanCallback> mScanCallback = new ThreadLocal<ScanCallback>() {

    @Override
    protected ScanCallback initialValue() {
        return new ScanCallback() {
            @Override
            public void onScanResult(int callbackType, ScanResult result) {
                ScanRecord btScanRecord = result.getScanRecord();
                //Log.i(TAG,"new johoksdfjkhdfsj");//Not Called
                if (btScanRecord != null) {
                }
                Connect();
                //Log.i(TAG,"new johoksdfjkhdfsj");//Not Called
            }

            @Override
            public void onBatchScanResults(List<ScanResult> results) {
                for (ScanResult sr : results) {
                    Log.i("ScanResult-Results", sr.toString());
                    //Log.i(TAG, sr.toString());//not called
                }
            }

            @Override
            public void onScanFailed(int errorCode) {
                Log.e("Scan Failed", "Error Code: " + errorCode);
            }
        };
    }
};

我只想要rssi，timestamp和mac-address，但我认为这段代码给了我一些其他字符串，如制造商详情，广告标志等。

试试这个BLE Scan听众：

 public BluetoothAdapter.LeScanCallback mLeScanCallback =
                new BluetoothAdapter.LeScanCallback() {

            @Override
            public void onLeScan(final BluetoothDevice device, final int rssi, byte[] scanRecord) {
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        // also get address using
                          // device.getAddress();
                           addDevice(device,rssi);  

                          String currentDateTimeString = DateFormat.getTimeInstance().format(new Date());
                         Log.e("In h:m:s"," "+currentDateTimeString);

                        Long tsLong = System.currentTimeMillis()/1000;
                        String ts = tsLong.toString();
                        Log.e("In miliseconds"," "+ts);
                    }
                });
            }
        };

我希望这项工作。
