接上文:

1. 獲取藍芽介面卡:

// 得到本機藍芽裝置

mbluetoothadapter = bluetoothadapter.getdefaultadapter();

if (mbluetoothadapter != null) else

2. 新增監聽:

void registerbleutoothstatereceiver()
3. 獲取裝置:

已繫結:

// 獲得已配對的遠端藍芽裝置的集合

setdevices = mbluetoothadapter.getbondeddevices(); 

掃瞄:

/**

* 在開始掃瞄前, 注意檢測是否正在掃瞄.

* start discovery bluetooth devices

* @param force

*/void startdiscovery(boolean force)else

}mbluetoothadapter.startdiscovery();

}

掃瞄到裝置後, 會有廣播:

if(bluetoothdevice.action_found.equals(action))
獲取已連線裝置:

//可以理解為兩個**, 

private bluetoothheadset mbluetoothheadset=null;

private bluetootha2dp mbluetootha2dp=null;

private bluetoothprofile.servicelistener mheadsetprofileservicelistener = new bluetoothprofile.servicelistener()

@override

public void onserviceconnected(int arg0, bluetoothprofile profile)

}; private bluetoothprofile.servicelistener mprofileservicelistener = new bluetoothprofile.servicelistener()

//get profile after bluetooth was enabled

mbluetoothadapter.getprofileproxy(activitybluetooth.this, mprofileservicelistener, bluetoothprofile.a2dp);

mbluetoothadapter.getprofileproxy(activitybluetooth.this, mheadsetprofileservicelistener, bluetoothprofile.headset);

/** 記得在用完後, 去close 掉 **/

if(mbluetootha2dp != null)mbluetoothadapter.closeprofileproxy(bluetoothprofile.a2dp, mbluetootha2dp);

if(mbluetoothheadset != null)mbluetoothadapter.closeprofileproxy(bluetoothprofile.headset, mbluetoothheadset);

4. 配對裝置:

呼叫bluetoothdevice.createbond();

處理狀態廣播:

if(bluetoothdevice.action_bond_state_changed.equals(action))
5. 連線裝置:

boolean debugconnect = true;

/** connect bluetooth device **/

boolean connectdevice(bluetoothdevice device)

if(debugconnect)alog.d(tag, "try connect to " + device.getname());

boolean result = false;

try catch (illegalacces***ception e) catch (illegalargumentexception e) catch (invocationtargetexception e) catch (nosuchmethodexception e)

return result;

}

監聽連線狀態:

if(bluetoothadapter.action_connection_state_changed.equals(action))else if(state == bluetoothadapter.state_connecting)else

}

6. 取消配對:

boolean debugunpair = true;

/** unpair device **/

void unpairdevice()elseelse if(device.getbondstate() == bluetoothdevice.bond_bonded)

if(debugunpair)alog.d(tag, "unpair device " + device.getname() + (result ? " success" : " failed"));

} catch (exception e)

} }

// 取消正在配對  

private boolean cancelbondprocess(class bclass,

bluetoothdevice device) throws exception

private boolean removebond(class blass, bluetoothdevice device)

throws exception

7. 斷開連線:

boolean disconnectheadset(bluetoothdevice device)

} catch (nosuchmethodexception e) catch (illegalacces***ception e) catch (illegalargumentexception e) catch (invocationtargetexception e)

return false; }

boolean disconnecta2dp(bluetoothdevice device)

} catch (nosuchmethodexception e) catch (illegalacces***ception e) catch (illegalargumentexception e) catch (invocationtargetexception e)

return true;

}

ps: 在做其它操作前, 注意取消掃瞄:

if (mbluetoothadapter.isdiscovering())  ;

以上**僅適應藍芽音箱或藍芽耳機, 其它種類的裝置暫未相容測試.

另外, 小公尺三星等廠商對wifi/bt這一部分的**或平台相容性上做了不少事情.

以上**相容性上存在不少問題, 僅僅為了整理和記錄,
