Comment obtenir les appareils bluetooth comme une liste?

j'essaie d'obtenir mon cautionné les appareils bluetooth, mais je peux l'obtenir comme une longue chaîne, au lieu de la liste.

voici mon code:

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));

j'obtiens quelque chose comme ceci: [00:23:7F:1c, f0:09:f1:b4:b0]. Et le tout dans une seule ligne. Comment puis-je le changer en une liste et non pas sur une seule ligne?

en outre, Comment puis-je obtenir les noms amicaux des appareils et pas ces numéros?

Merci!!!

Vous devriez changer votre code comme suit:

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));

dans ce code vous avez juste besoin d'appeler cela dans votre clic de bouton.

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);
