Question

我有一个名为scan的按钮，用于扫描可用的蓝牙设备并制作列表视图。当我按下该设备列表中的某些设备时，我正在调用ConnectThread（BluetoothDevice设备），但是如何使用下面的代码将点击的设备地址发送到此。这是能够获得名称但是如何获取地址

  ListView lv = getListView();

        // listening to single list item on click
        lv.setOnItemClickListener(new OnItemClickListener() {
          public void onItemClick(AdapterView<?> parent, View view,
              int position, long id) {

              mBluetoothAdapter.cancelDiscovery();
            // Toast.makeText(getApplicationContext(), "clicked device", 2).show();
              String address = mArrayAdapter.get(position);
              device = mBluetoothAdapter.getRemoteDevice(address);

              new ConnectThread(device);
          }
        });

ConnectThread代码：

 private class ConnectThread extends Thread {
    private final BluetoothSocket mmSocket;
    private final BluetoothDevice mmDevice;

    public ConnectThread(BluetoothDevice device) {
        // Use a temporary object that is later assigned to mmSocket,
        // because mmSocket is final
        BluetoothSocket tmp = null;
        mmDevice = device;
        Toast.makeText(getApplicationContext(), "device: " + device, 2).show();
        // Get a BluetoothSocket to connect with the given BluetoothDevice
        try {
            // MY_UUID is the app's UUID string, also used by the server code
            tmp = device.createRfcommSocketToServiceRecord(MY_UUID);
        } catch (IOException e) { }
        mmSocket = tmp;
    }
    public void run() {
        // Cancel discovery because it will slow down the connection
        mBluetoothAdapter.cancelDiscovery();

        try {
            // Connect the device through the socket. This will block
            // until it succeeds or throws an exception
            mmSocket.connect();
        } catch (IOException connectException) {
            // Unable to connect; close the socket and get out
            try {
                mmSocket.close();
            } catch (IOException closeException) { }
            return;
        }

        // Do work to manage the connection (in a separate thread)
       // manageConnectedSocket(mmSocket);
    }

    /** Will cancel an in-progress connection, and close the socket */
    public void cancel() {
        try {
            mmSocket.close();
        } catch (IOException e) { }
    }
}

我找到了这个问题的答案。当我在列表视图中单击项目时，在代码下方使用。

        ListView lv = getListView();

        // listening to single list item on click
        lv.setOnItemClickListener(new OnItemClickListener() {
          public void onItemClick(AdapterView<?> parent, View view,
              int position, long id) {

              mBluetoothAdapter.cancelDiscovery();

              String info = mArrayAdapter.get(position);
              String address = info.substring(info.length() - 17);
              device = mBluetoothAdapter.getRemoteDevice(address);
              new ConnectThread(device);

          }
        });

将设备地址发送到android-bluetooth中的ConnectThread（BluetoothDevice设备）
