1.获得蓝牙适配器

mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();

2.蓝牙的打开和关闭

if (!mBluetoothAdapter.isEnabled()) {    new Thread(new Runnable() {        @Override        public void run() {            mBluetoothAdapter.enable();        }    }).start();}

if (mBluetoothAdapter.isEnabled())    mBluetoothAdapter.disable();

3.扫描蓝牙

if (mBluetoothAdapter.isDiscovering()) {    mBluetoothAdapter.cancelDiscovery();}mBluetoothAdapter.startDiscovery();Toast.makeText(getBaseContext(), "正在搜索设备......", Toast.LENGTH_SHORT).show();

4.蓝牙状态变化都会有广播

if (BluetoothAdapter.ACTION_STATE_CHANGED.equals(intent.getAction())) {//蓝牙状态改变    Log.i("ACTION_STATE_CHANGED", "----------");    setPairListView();} else if (BluetoothDevice.ACTION_BOND_STATE_CHANGED.equals(intent.getAction())) {//绑定不同设备状态改变    Log.i("BOND_STATE_CHANGED", "----------");    if (device.getBondState() == BluetoothDevice.BOND_BONDED) {        //如果绑定的设备跟点击的设备名称相同，表示配对成功，保存进蓝牙路径；        if (device.getName().equals(mDevice)) {            mFileStore.writeBluetooth(mDevice);        }        //更新mPairListView和mNewListView        for (String s : mNewDatas) {            if (s.equals(device.getName())) {                mNewDatas.remove(s);                setNewListView();                setPairListView();                return;            }        }    }    setPairListView();} else if (BluetoothDevice.ACTION_FOUND.equals(intent.getAction())) {//搜索到设备    Log.i("ACTION_FOUND", "----------");    newDevices.add(device);    if (device.getBondState() != BluetoothDevice.BOND_BONDED) {        if (mNewDatas.size() > 0) {            boolean exist = false;            Log.i("aaa", "onReceive: " + mNewDatas.toString());            for (String s : mNewDatas) {                if (s.equals(device.getName())) {                    exist = true;                }            }            if (!exist) {                mNewDatas.add(device.getName());            }        } else {            mNewDatas.add(device.getName());        }        setNewListView();    }} else if (BluetoothAdapter.ACTION_DISCOVERY_STARTED.equals(intent.getAction())) {//搜索状态改变    Log.i("DISCOVERY_STARTED", "----------");    mNewDatas.clear();    setNewListView();}

5.绑定配对蓝牙

mDevice = mNewDatas.get(position);if (mBluetoothAdapter.isDiscovering()) {    mBluetoothAdapter.cancelDiscovery();}Toast.makeText(getBaseContext(), "正在配对......", Toast.LENGTH_SHORT).show();for (BluetoothDevice device : newDevices) {    if (device.getName().equals(mNewDatas.get(position))) {        Log.i("mNewListView", "----------device.getName():" + device.getName());        try {            Method createBondMethod = BluetoothDevice.class.getMethod("createBond");            createBondMethod.invoke(device);        } catch (Exception  e) {            e.printStackTrace();        }        return;    }}

6.获得已绑定的蓝牙

pairedDevices = mBluetoothAdapter.getBondedDevices();

7.链接蓝牙（）绑定蓝牙之后就是以配对蓝牙以配对蓝牙就可以链接了。）

//链接蓝牙设备private void connectBluetooth(BluetoothDevice device) {    // 固定的UUID    final String SPP_UUID = "00001101-0000-1000-8000-00805F9B34FB";    UUID uuid = UUID.fromString(SPP_UUID);    try {        device.createRfcommSocketToServiceRecord(uuid).connect();    } catch (IOException e) {        e.printStackTrace();        runOnUiThread(new Runnable() {            @Override            public void run() {                Toast.makeText(BluetoothActivity.this, "连接失败！", Toast.LENGTH_SHORT).show();            }        });    }}

至于传统蓝牙的传输暂时没有做过，不过ble蓝牙的链接，传输数据是有做过的。晚点上传
