如何使用蓝牙查找范围内的设备？

我是 android 新手。我想开发一个应用程序，通过编程方式使用蓝牙来查找范围内的设备。如果有人有想法，请给我一些示例代码。

Find The Devices in the Range by using Bluetooth programmatically.

是的，你可以使用以下方法来做到这一点广播接收器 http://developer.android.com/reference/android/content/BroadcastReceiver.html，看看下面的代码，它会对你有帮助。

开始搜索

mBluetoothAdapter.startDiscovery(); 
mReceiver = new BroadcastReceiver() {
public void onReceive(Context context, Intent intent) {
    String action = intent.getAction();

找到设备

    if (BluetoothDevice.ACTION_FOUND.equals(action)) 
    {
        // Get the BluetoothDevice object from the Intent
        BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
        // Add the name and address to an array adapter to show in a ListView
       mArrayAdapter.add(device.getName() + "\n" + device.getAddress());
    }
  }
};

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