  // Bluetoothアダプタが利用可能か調べる
  BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();

  //ペアディバイスの表示
  Set pairedDevices = mBluetoothAdapter.getBondedDevices();

  //ペアディバイスをListViewに表示
  //ListView を取得
        ListView listView = (ListView) findViewById(R.id.listView1);
        //ListView のアダプタ設定
  ArrayAdapter mArrayAdapter = new ArrayAdapter(this, android.R.layout.simple_list_item_1);
  
  if (pairedDevices.size() > 0) {
      // Loop through paired devices
      for (BluetoothDevice device : pairedDevices) {
          // Add the name and address to an array adapter to show in a ListView
          mArrayAdapter.add(device.getName() + "\n" + device.getAddress());

      }
