Bluetoothデバイスをリストとして取得する方法は？

ボンディングされたBluetoothデバイスを取得しようとしていますが、リストではなく長い文字列として取得できます。

これは私のコードです：

BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices();
ArrayList<String> listview = 
new ArrayList<String>(Arrays.asList(pairedDevices.toString()));
setListAdapter(new ArrayAdapter<String>(this, R.layout.list, listview));

私はこのようなものを得ています：[00:23:7F:1c, f0:09:f1:b4:b0]。そして、そのすべてが一列に並んでいます。すべてを1行でなくリストに含めるにはどうすればよいですか？

また、これらの番号ではなく、デバイスのわかりやすい名前を取得するにはどうすればよいですか？

ありがとう!!!

以下のようにコードを変更する必要があります。

BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices();

List<String> s = new ArrayList<String>();
for(BluetoothDevice bt : pairedDevices)
   s.add(bt.getName());

setListAdapter(new ArrayAdapter<String>(this, R.layout.list, s));
