我剛開始學習Android開發。我正在編寫一個Android程序來掃描可用的藍牙設備並將它們列入日誌文件中。由於我是Android新手,因此無法找出以下代碼段中的錯誤。在android中發現可用的藍牙設備
button2.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
ListView lv1 = (ListView) findViewById(R.id.myListView1);
BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
final BroadcastReceiver mReceiver = new BroadcastReceiver()
{
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);
Log.v("BlueTooth Testing",device.getName() + "\n"
+ device.getAddress());
}
}
};
String aDiscoverable = BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE;
startActivityForResult(new Intent(aDiscoverable),DISCOVERY_REQUEST);
IntentFilter filter = new IntentFilter(BluetoothDevice.ACTION_FOUND);
registerReceiver(mReceiver, filter);
mBluetoothAdapter.startDiscovery();
}
});
當我嘗試調試模式,控制跳過了「BroadcastReceiver()
」。我在日誌中找不到任何條目。你能幫我弄清楚問題是什麼,以及如何列出可用的藍牙設備。

不知道爲什麼你標記basic4android這個問題。如果你想用Basic4android實現它,你應該看到這個[manual](http://www.basic4ppc.com/android/help/serial.html#bluetoothadmin)。 – Erel
對不起,我是Android新手,我以爲Basic4android是一個獲得有關基本android編程的答案的地方。我想用Java解決這個問題 – SyncMaster
