android bluetooth已知了bluetoothDevice的mac地址 怎么得到bluetoothDevice

android bluetooth得到了bluetoothDevicemac地址（不是搜索配对得到的） 接下来怎么生成bluetoothSocket （msocket=bluetoothDevice.creatRfcommSocketToServiceRecord(UUID 知道了bluetoothDevice的mac 怎么得到这个bluetoothDevice？)

Answer 1

使用BluetoothAdapter类提供的方法getRemoteDevice 创建BluetoothDevice实例。
提醒一句，BluetoothAdapter实例应使用 BluetoothAdapter.getDefaultAdapter ()静态方法获取。

以下摘译自android文档。

public BluetoothDevice getRemoteDevice (String address)

Since: API Level 5
Get a BluetoothDevice object for the given Bluetooth hardware address.
Valid Bluetooth hardware addresses must be upper case, in a format such as "00:11:22:33:AA:BB". The helper checkBluetoothAddress(String) is available to validate a Bluetooth address.
通过指定的硬件地址获取BluetoothDevice对象。有效的蓝牙硬件地址必须是形如"00:11:22:33:AA:BB"的大写字符串。可使用辅助方法checkBluetoothAddress(String)校验地址（格式）的有效性。

A BluetoothDevice will always be returned for a valid hardware address, even if this adapter has never seen that device.
如地址有效则一个对应的BluetoothDevice对象被返回，即使适配器并未发现该设备。

Parameters 参数
address valid Bluetooth MAC address 有效的蓝牙MAC地址

Throws
IllegalArgumentException if address is invalid
