安卓蓝牙-MAC地址

【中文标题】安卓蓝牙-MAC地址

【英文标题】：Android Bluetooth- MAC address

【问题描述】：

当我单击列表视图中的设备时，我试图获取蓝牙设备的 MAC 地址。我想在

中传入 MAC 地址

BluetoothDevice device = mBluetoothAdapter.getRemoteDevice(address);

当我在列表视图中选择一个设备时，有没有一种方法可以提取 MAC 地址。谢谢

 @Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) 
    if (mBluetoothAdapter.isDiscovering()) 
        mBluetoothAdapter.cancelDiscovery();
    
    if (listAdapter.getItem(i).contains("Paired")) 

        BluetoothDevice selectedDevice = devices.get(i);
        BluetoothDevice device = mBluetoothAdapter.getRemoteDevice(address);
        mBluetoothAdapter.cancelDiscovery();
        try 
            btSocket = device.createRfcommSocketToServiceRecord(MY_UUID);
            btSocket.connect();

         catch (IOException e) 
            try 
                btSocket.close();
             catch (IOException e2) 
            
        
    
    

【参考方案1】：

在 android 中，启动蓝牙设备扫描后，我们会获得远程蓝牙设备的地址，作为我们注册的 BroadcastReceiver 上的广播消息。下面的代码示例就是这样做的。

//receive remote device details including address
BroadcastReceiver mReceiver = new BroadcastReceiver() 
    public void onReceive(Context context, Intent intent) 
        Sring action = intent.getAction();

        // When discovery finds a device
        if (BluetoothDevice.ACTION_FOUND.equals(action)) 
            // Get the BluetoothDevice object from the Intent
            BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
            String deviceAddress =  device.getAddress());
        
    


//register receiver 
IntentFilter filter = new IntentFilter(BluetoothDevice.ACTION_FOUND);
registerReceiver(mReceiver, filter); 

//start bluetooth scan 
BluetoothAdapter mBtAdapter = BluetoothAdapter.getDefaultAdapter();
mBtAdapter.startDiscovery();

为了回答您的具体案例，我假设您正在使用BluetoothChat(1) Android 示例代码在扫描后从配对设备创建 ListView。如果是这种情况，您可以在 Android 代码示例中获取设备地址（2）

public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) 
    String info = ((TextView) view).getText().toString();
    String address = info.substring(info.length() - 17);
