Custom list adapter and ListView

For the UI purposes, it is good to have a custom list adapter that shows the name and address of the scanned Bluetooth device in the list. For this purpose, we created a custom adapter class BluetoothLeListAdapter extending the BaseAdapter.

public BluetoothLeListAdapter(Activity baseActivity) {     super();     mLeDevices = new ArrayList<BluetoothDevice>();     mInflator = (LayoutInflater) baseActivity.getSystemService(Context.LAYOUT_INFLATER_SERVICE); }

In the addDevice method, mLeDevices are updated with newly scanned devices. This task will be achieved by:

 public void addDevice(BluetoothDevice ...
