首先确保将这些权限添加到您的应用清单文件中：

<uses-permission android:name="android.permission.BLUETOOTH"></uses-permission>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"></uses-permission>

现在做：

BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();

 if (bluetoothAdapter == null) {
   // device doesn't support bluetooth
 }
 else {

   // bluetooth is off, ask user to on it.
   if(!bluetoothAdapter.isEnabled()) {
       Intent enableAdapter = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
       startActivityForResult(enableAdapter, 0);
   }

   // Do whatever you want to do with your bluetoothAdapter
   Set<BluetoothDevice> all_devices = bluetoothAdapter.getBondedDevices();
    if (all_devices.size() > 0) {
        for (BluetoothDevice currentDevice : all_devices) {
            log.i("Device Name " + currentDevice.getName());
        }
    }
}
