Java 如何将信标名称插入数据库？

我需要提取可扩展的设备名并将其放入sqlite中的一个表中。我使用了谷歌的示例代码，并对其进行了修改，以实现我的目标。除表中的设备名称外，所有部件都工作。我可以吐司的设备名称，这意味着该方法的工作，但我不知道我应该把插入命令：插入设备名称表

myDb.insertData("1",device.getName(),date);

这是我的扫描活动

package com.example.android.bluetoothlegatt;


public class DeviceScanActivity extends ListActivity {

    DatabaseHelper myDb;
    //String beaconName;
    String date = new SimpleDateFormat("ddMMyyHHmmss").format(new Date());

    @Override

        super.onCreate(savedInstanceState);
        getActionBar().setTitle(R.string.title_devices);
        mHandler = new Handler();
        myDb=new DatabaseHelper(this);

        myDb.insertData("1", getName() , date);

        if    (!getPackageManager().hasSystemFeature(PackageManager.FEATURE_BLUETOOTH_LE)) {
            Toast.makeText(this, R.string.ble_not_supported, Toast.LENGTH_SHORT).show();

插入命令是否可以像这样放置在

mLeScanCallback

中

...

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

            @Override
            public void onLeScan(final BluetoothDevice device, int rssi, byte[]   scanRecord) {

                // insert the device into the SQLite database
                String date = new SimpleDateFormat("ddMMyyHHmmss").format(new Date());
                myDb.insertData(device.getAddress(), device.getName() , date);

                // add device to list displayed on GUI
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        mLeDeviceListAdapter.addDevice(device);
                        mLeDeviceListAdapter.notifyDataSetChanged();
                    }
                });
            }
        };

上面的代码使用传入回调的

BluetoothDevice设备的mac地址作为插入命令的
MobileId
。
Hello@ebi nadian，我对您的问题有几个问题。正在插入数据库的名称是通过蓝牙连接到的设备的名称，还是本地设备的名称？应用程序能否连接到多个其他设备？“myTable”表应该跟踪什么？如果能提供上述问题的答案，将有助于我们更好地理解您的问题。特别是最后一个。嗨，埃里克，第一个mytable在应用程序数据库中，所有数据都应该在那里。该应用程序假设通过GATT数据包扫描所有BLE设备（信标）。GATT数据包中有很多信息，比如设备（信标）名称、MAC地址…，我只需要获取设备名称（BeaconName）+时间+一个常量值（例如数字5）并传递给sqlite。但我的问题是变量device.getName（）；不要传播到所有方法（它仅在自己的方法中可访问，尽管不是私有的）。它可以工作，谢谢，关于主键，根据场景，特定移动电话中的每个记录的MobileID列必须相同，唯一的变量数据是信标名称和时间，因为有几部手机在不同的区域收集数据，最后所有的数据都应该合并到一个数据库中。哦，我明白了，好的。我将编辑我的答案以修复它。我很高兴能帮上忙！！
