¿Cómo obtener los dispositivos bluetooth como una lista?

Question

Estoy tratando de obtener mis dispositivos vinculados con bluetooth, pero puedo obtenerlo como una cadena larga en lugar de lista.

Este es mi código:

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)); 

Me estoy haciendo algo como esto: [00:23:7F:1c, f0:09:f1:b4:b0]. Y todo en una línea. ¿Cómo puedo cambiarlo para que esté en una lista y no todo en una línea?

Además, ¿cómo puedo obtener los nombres descriptivos de los dispositivos y no estos números?

Gracias !!!

Answer 1

Debe cambiar el código de la siguiente manera:

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));

He probado el código de abajo,

main.xml

    > 
<TextView 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello" 
    /> 
<TextView

En este código sólo tiene que llamar a esto en su clic de botón.

private void list_paired_Devices() { 
     Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices(); 
     ArrayList<String> devices = new ArrayList<>(); 
     for (BluetoothDevice bt : pairedDevices) { 
      devices.add(bt.getName() + "\n" + bt.getAddress()); 
     } 
     ArrayAdapter arrayAdapter = new ArrayAdapter(bluetooth.this, android.R.layout.simple_list_item_1, devices); 
     emp.setAdapter(arrayAdapter); 
    }
