Question

我在android中通过蓝牙发送图像，想要获取正在发送图像的设备的MAC地址。

请在下面找到我的代码。

private void bluetoothadd(){
    BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
    if (mBluetoothAdapter == null) {
        // Device does not support Bluetooth

        Log.e("Bluetooth ","not found");
    }

    if (!mBluetoothAdapter.isEnabled()) {
        Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
        startActivity(enableBtIntent);

        Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices();
        // If there are paired devices
        if (pairedDevices.size() > 0) {
            // Loop through paired devices
            for (BluetoothDevice device : pairedDevices) {


                Log.e("Mac Addressess","are:  "+mBluetoothAdapter.getRemoteDevice(device.getAddress()));
            }
            }
        }

}

我正在获取所有配对设备的MAC地址。我只想要设备的MAC地址传输数据。

Answer 1

使用此：

BluetoothDevice device = mBluetoothAdapter.getRemoteDevice(address);

Answer 2

当触发意图以连接到远程设备并且设备成功建立时，设备地址将作为带有标记EXTRA_DEVICE_ADDRESS的额外数据返回。

您可以检查连接并建立连接

if (!mBluetoothAdapter.isEnabled()) {
            Intent enableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
            startActivityForResult(enableIntent, REQUEST_ENABLE_BT);

您可以查看on onActivityResult功能中的活动，找到这样的地址

public void onActivityResult(int requestCode, int resultCode, Intent data) {

        switch (requestCode) {
        case REQUEST_CONNECT_DEVICE:
            // When DeviceListActivity returns with a device to connect
            if (resultCode == Activity.RESULT_OK) {
                // Get the device MAC address
                 String add = data.getExtras()
                                     .getString(DeviceListActivity.EXTRA_DEVICE_ADDRESS);
                address= add.toString();

                 // Get the BluetoothDevice object
                BluetoothDevice device = mBluetoothAdapter.getRemoteDevice(address);

            }
            break; 
}
}

此技巧用于您可以在SDK的Examples文件夹中找到的蓝牙聊天示例应用程序

Answer 3

 private String connectedDeviceAdd = "";
 private BluetoothDevice connectedDevice;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    registerReceiver(this.mReceiver, new IntentFilter(BluetoothDevice.ACTION_ACL_CONNECTED));




 private final BroadcastReceiver mReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();

        if (BluetoothDevice.ACTION_ACL_CONNECTED.equals(action)) {
            // Get the BluetoothDevice object from the Intent
            BluetoothDevice device = intent
                    .getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);

            connectedDeviceAdd = device.getAddress();
            connectedDevice = BluetoothAdapter.getDefaultAdapter().getRemoteDevice(connectedDeviceAdd);

        } else if (BluetoothDevice.ACTION_ACL_DISCONNECTED.equals(action)) {
            Log.e(TAG, "Device Disconnected");

        }
    }
};



 @Override
    protected void onDestroy() {
        super.onDestroy();
        unregisterReceiver(this.mReceiver);
    }

Answer 4

所以，听起来你想要获得与你有连接的设备的bd_addr / mac？然后请注意，BluetoothSocket类有一个成员'getRemoteDevice'，它返回一个代表你所连接设备的BluetoothDevice实例，你可以在其上调用getAddress（）来获取MAC。

或者您可以注册ACTION_ACL_CONNECTED，其中包含“EXTRA_DEVICE”，可以引导您进入BluetoothDevice。

Answer 5

这项工作对我来说：

String macAddress = android.provider.Settings.Secure.getString(mContext.getContentResolver(), "bluetooth_address");

Answer 6

试试吧。

WifiManager manager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiInfo info = manager.getConnectionInfo();
String address = info.getMacAddress();
