在Android服务上连接蓝牙

我找到了用于管理服务连接的示例代码。但我不知道如何使用它。在Android服务上连接蓝牙

我只写在这里，我不明白的代码，看到所有的代码：

CODE

public int onStartCommand(Intent intent, int flags, int startId) { 
    Log.d("popopo", "Onstart Command"); 
    mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter(); 
    if (mBluetoothAdapter != null) { 
     device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE); 
     deviceName = device.getName(); 
     String macAddress = device.getAddress(); 
     if (macAddress != null && macAddress.length() > 0) { 
      connectToDevice(macAddress); 
     } else { 
      stopSelf(); 
      return 0; 
     } 
    } 
    String stopservice = intent.getStringExtra("stopservice"); 
    if (stopservice != null && stopservice.length() > 0) { 
     stop(); 
    } 
    return START_STICKY; 
}

我连接正确地将没有服务蓝牙，使用此代码获取设备：

if (BluetoothDevice.ACTION_FOUND.equals(action)) { 
    // Get the BluetoothDevice object from the Intent 
    BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE); 
    // Add the name and address to an array adapter to show in a ListView 
    mArrayAdapter.add(device.getName() + "\n" + device.getAddress()); 
}

我的问题是：当onStartCommand()要执行时如何通过我发现的蓝牙设备ID？

当我没有执行ACTION_FOUND时，它试图连接哪个蓝牙设备？

可能有点晚，但以防万一。如果我记得正确，有许多方法可以连接到设备，因为它的mac地址。

将设备的地址作为额外的创建意图传递。

在UI活动

Intent intent=new Intent(this,BluetoothService.class)); 
intent.putExtra("DEVICE_ADDRESS",device.getAddress()); 

startService(intent);

在蓝牙服务

public int onStartCommand(Intent intent, int flags, int startId) { 
    String address = intent.getExtras("DEVICE_ADDRESS"); 

    ###DO SOMETHING WITH ADDRESS HERE### 
}

创建您服务 'connectToDevice（字符串地址）' 的方法，并在任何地方你都叫它您的BroadcastReceiver。

在蓝牙服务

protected synchronized void connectToDevice(BluetoothDevice device){//Cancells any threads attempting to connect and starts a new connectThread (new connection) 

    if (mConnectThread != null) { 
     mConnectThread.cancel(); 
     mConnectThread = null; 
     Log.d(TAG,"Cancelled connectThread"); 
    } 


    if (mConnectedThread != null) { 
     mConnectedThread.cancel(); 
     mConnectedThread = null; 
     Log.d(TAG,"Cancelled connectedThread"); 

    } 

    mConnectThread = new ConnectThread(device); 
    mConnectThread.start(); 
    Log.d(TAG,"Starting connectThread"); 
}

广播接收机

if (BluetoothDevice.ACTION_FOUND.equals(action)) { 
    // Get the BluetoothDevice object from the Intent 
    BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE); 
    // Add the name and address to an array adapter to show in a ListView 
    mArrayAdapter.add(device.getName() + "\n" + device.getAddress()); 
    BluetoothService mBluetoothService = new BluetoothService(); 
    mBluetoothService.connectToDevice(device.getAddress()); 

}

你应该检查出由Android提供的BluetoothChat example。我认为这显示了你需要的很多东西。
