如何知道connect（）是否成功进行蓝牙连接

Question

有没有办法知道connect（）方法是否成功？

我在ConnectThread类中有代码：

public void run() {
    // Cancel discovery because it will slow down the connection
    mBluetoothAdapter.cancelDiscovery();

    try {
        // Connect the device through the socket. This will block
        // until it succeeds or throws an exception
        mmSocket.connect();
    } catch (IOException connectException) {
        // Unable to connect; close the socket and get out
        try {
            mmSocket.close();
        } catch (IOException closeException) { }
        return;
    }
}

并尝试将此主题连接为：

BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices();
if (pairedDevices.size() > 0) 
{
    // Loop through paired devices
    for (BluetoothDevice device : pairedDevices) 
    {
        if (device.getName().equals("HC-06"))
        {
            Thread initialThread = new ConnectThread(device);
            initialThread.run();
        }
    }
}

我想知道这种连接是否成功。任何帮助将不胜感激！

如果它没有成功，它将抛出异常。如果在connect（）调用之后到达语句，则成功。
