Android +以编程方式通过蓝牙配对设备
我想发现范围内的bluetooth设备，列表和点击它们对。 我使用下面的代码，但它只是closures应用程序，当我点击设备名称，我想配对。
我想知道我的代码中的错误或任何其他方式来做我所需要的。

在我的第一个答案中，逻辑显示了那些想要只用逻辑的人。
我想我无法向@ chalukya3545说清楚，这就是为什么我要添加整个代码让他知道代码的确切stream程。

这是main.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <Button android:id="@+id/buttonOn" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="On"/> <Button android:id="@+id/buttonDesc" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Make Discoverable"/> <Button android:id="@+id/buttonSearch" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="Search"/> <Button android:id="@+id/buttonOff" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="Bluetooth Off"/> <ListView android:id="@+id/listViewPaired" android:layout_width="match_parent" android:layout_height="120dp"> </ListView> <ListView android:id="@+id/listViewDetected" android:layout_width="match_parent" android:layout_height="match_parent"> </ListView> </LinearLayout>
将此权限添加到您的AndroidManifest.xml文件中：
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" /> <uses-permission android:name="android.permission.BLUETOOTH" /> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
此代码的输出将如下所示。 
最好的方法是不要使用任何配对代码 。 而不是onClick转到其他function或其他您使用UUID创build套接字的类。
如果已经没有配对，Android会自动popup配对。
或者看看这个链接，以更好的理解
以下是相同的代码：
private OnItemClickListener mDeviceClickListener = new OnItemClickListener() { public void onItemClick(AdapterView<?> av, View v, int arg2, long arg3) { // Cancel discovery because it's costly and we're about to connect mBtAdapter.cancelDiscovery(); // Get the device MAC address, which is the last 17 chars in the View String info = ((TextView) v).getText().toString(); String address = info.substring(info.length() - 17); // Create the result Intent and include the MAC address Intent intent = new Intent(); intent.putExtra(EXTRA_DEVICE_ADDRESS, address); // Set result and finish this Activity setResult(Activity.RESULT_OK, intent); // **add this 2 line code** Intent myIntent = new Intent(view.getContext(), Connect.class); startActivityForResult(myIntent, 0); finish(); } };
Connect.java文件是：
public class Connect extends Activity { private static final String TAG = "zeoconnect"; private ByteBuffer localByteBuffer; private InputStream in; byte[] arrayOfByte = new byte[4096]; int bytes; public BluetoothDevice mDevice; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.connect); try { setup(); } catch (ZeoMessageException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (ZeoMessageParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } } private void setup() throws ZeoMessageException, ZeoMessageParseException { // TODO Auto-generated method stub getApplicationContext().registerReceiver(receiver, new IntentFilter(BluetoothDevice.ACTION_ACL_CONNECTED)); getApplicationContext().registerReceiver(receiver, new IntentFilter(BluetoothDevice.ACTION_ACL_DISCONNECTED)); BluetoothDevice zee = BluetoothAdapter.getDefaultAdapter(). getRemoteDevice("**:**:**:**:**:**");// add device mac adress try { sock = zee.createRfcommSocketToServiceRecord( UUID.fromString("*******************")); // use unique UUID } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } Log.d(TAG, "++++ Connecting"); try { sock.connect(); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } Log.d(TAG, "++++ Connected"); try { in = sock.getInputStream(); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } Log.d(TAG, "++++ Listening..."); while (true) { try { bytes = in.read(arrayOfByte); Log.d(TAG, "++++ Read "+ bytes +" bytes"); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } Log.d(TAG, "++++ Done: test()"); }} private static final LogBroadcastReceiver receiver = new LogBroadcastReceiver(); public static class LogBroadcastReceiver extends BroadcastReceiver { @Override public void onReceive(Context paramAnonymousContext, Intent paramAnonymousIntent) { Log.d("ZeoReceiver", paramAnonymousIntent.toString()); Bundle extras = paramAnonymousIntent.getExtras(); for (String k : extras.keySet()) { Log.d("ZeoReceiver", " Extra: "+ extras.get(k).toString()); } } }; private BluetoothSocket sock; @Override public void onDestroy() { getApplicationContext().unregisterReceiver(receiver); if (sock != null) { try { sock.close(); } catch (IOException e) { e.printStackTrace(); } } super.onDestroy(); } }
编辑：我刚刚解释了在这里配对的逻辑。 如果有人想用完整的代码去看看我的另一个答案。 我已经在这里回答了逻辑，但我无法正确解释，所以我在同一个线程中添加了另一个答案。
试试这个做配对：
如果你能够search设备，那么这将是你的下一个步骤
ArrayList<BluetoothDevice> arrayListBluetoothDevices = NEW ArrayList<BluetoothDevice>;
我假设你已经在arrayListBluetoothDevices添加了蓝牙设备列表：
BluetoothDevice bdDevice; bdDevice = arrayListBluetoothDevices.get(PASS_THE_POSITION_TO_GET_THE_BLUETOOTH_DEVICE); Boolean isBonded = false; try { isBonded = createBond(bdDevice); if(isBonded) { Log.i("Log","Paired"); } } catch (Exception e) { e.printStackTrace(); }
createBond()方法：
public boolean createBond(BluetoothDevice btDevice) throws Exception { Class class1 = Class.forName("android.bluetooth.BluetoothDevice"); Method createBondMethod = class1.getMethod("createBond"); Boolean returnValue = (Boolean) createBondMethod.invoke(btDevice); return returnValue.booleanValue(); }
将此行添加到ACTION_FOUND中的Receiver中
if (device.getBondState() != BluetoothDevice.BOND_BONDED) { mNewDevicesArrayAdapter.add(device.getName() + "\n" + device.getAddress()); arrayListBluetoothDevices.add(device); }
我们为什么需要思考？ 有一个API可以做到这一点：
https://developer.android.com/reference/android/bluetooth/BluetoothDevice.html#createBond（）;
