Question

我愿意生成一个列表，其中列出了手机附近所有支持蓝牙功能的设备。我发现的代码没有配对的设备。有没有办法检索也配对的设备（如果它们落在附近）

发现附近所有设备的代码如下

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_bluetooth_connection);

    final TextView tv=(TextView)findViewById(R.id.textView1);
    BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();


    final BroadcastReceiver mReceiver = new BroadcastReceiver() 
    { 
        @Override
        public void onReceive(Context context, Intent intent) 
        {
            String 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);
            tv.append(device.getName() + "-"+ device.getAddress()+"\n"); 
            }
        }


    };
    String aDiscoverable = BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE;
    startActivityForResult(new Intent(aDiscoverable),DISCOVERY_REQUEST);
    IntentFilter filter = new IntentFilter(BluetoothDevice.ACTION_FOUND); 
    registerReceiver(mReceiver, filter); 
    mBluetoothAdapter.startDiscovery();
}

任何人都可以帮助我添加甚至发现配对设备的代码。

谢谢，

Answer 1

Set<BluetoothDevice> devices = adapter.getBondedDevices();
    for (BluetoothDevice device : devices) {
      tv.append(device);
    }

我没有测试过这个。它来自this tutorial。

检测包括已经配对的设备的区域中存在的所有蓝牙设备
