如何将蓝牙设备列表？

我试图让我的保税蓝牙设备，但我可以得到它作为一个长字符串，而不是列表。如何将蓝牙设备列表？

这是我的代码：

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));

我得到这样的：[00:23:7F:1c, f0:09:f1:b4:b0]。它的一切都在一条线上。如何将其更改为列表中，而不是全部在一行中？

另外，如何获得设备的友好名称而不是这些数字？

谢谢！

难道就实现了在列表的项目点击时会自动连接到配对的设备？ –

你应该如下更改代码：

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));

是啊！谢谢！！！只需要补充说我改了名单 s = new ArrayList （）; ArrayList s = new ArrayList （）;它现在效果很好。 – roiberg

查看更新后的答案 – waqaslam

在更新后有相同的错误。做了我以前做过的同样的改变，现在它可以工作。这是我给我修复的错误：类型列表不是通用的;它不能用参数参数化 – roiberg

我尝试下面的代码，

它是否通过点击连接到配对设备？ –

找到附近的蓝牙设备名单：

查找相同的屏幕截图。

enter image description here

MainActivity.java：

public class MainActivity extends ActionBarActivity { 

    private ListView listView; 
    private ArrayList<String> mDeviceList = new ArrayList<String>(); 
    private BluetoothAdapter mBluetoothAdapter; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     listView = (ListView) findViewById(R.id.listView); 

     mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter(); 
     mBluetoothAdapter.startDiscovery(); 

     IntentFilter filter = new IntentFilter(BluetoothDevice.ACTION_FOUND); 
     registerReceiver(mReceiver, filter); 

    } 


    @Override 
    protected void onDestroy() { 
     unregisterReceiver(mReceiver); 
     super.onDestroy(); 
    } 

    private final BroadcastReceiver mReceiver = new BroadcastReceiver() { 
     public void onReceive(Context context, Intent intent) { 
      String action = intent.getAction(); 
      if (BluetoothDevice.ACTION_FOUND.equals(action)) { 
       BluetoothDevice device = intent 
         .getParcelableExtra(BluetoothDevice.EXTRA_DEVICE); 
       mDeviceList.add(device.getName() + "\n" + device.getAddress()); 
       Log.i("BT", device.getName() + "\n" + device.getAddress()); 
       listView.setAdapter(new ArrayAdapter<String>(context, 
         android.R.layout.simple_list_item_1, mDeviceList)); 
      } 
     } 
    };

activity_main.xml中：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context="com.example.bluetoothdemo.MainActivity" > 

    <ListView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:id="@+id/listView"/> 

</RelativeLayout>

清单文件：

<?xml version="1.0" encoding="utf-8"?>

非常棒的男人。 – DavidBalas

@DavidBalas，很高兴为您效劳。 –

它是否连接到点击的配对设备？ –

在这段代码中，你只需要在你点击按钮来调用它。

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); 
    }
