Question

我正在努力解决与我的设备（三星Galaxy S6）中的蓝牙配对相关的问题。我有list-view，我在其中填充我的BLE设备名称，如下图

当用户点击任何BLE时，它应与该BLE配对。我的代码工作如下：

用于呼叫广播接收器（哄骗BLE名称）

// Quick permission check
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
int permissionCheck = getActivity().checkSelfPermission("Manifest.permission.ACCESS_FINE_LOCATION");
permissionCheck += getActivity().checkSelfPermission("Manifest.permission.ACCESS_COARSE_LOCATION");
if (permissionCheck != 0) {

this.requestPermissions(new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION}, 1001); //Any number
}
}

getActivity().registerReceiver(FoundReceiver, new IntentFilter(BluetoothDevice.ACTION_FOUND));
IntentFilter filter = new IntentFilter(BluetoothAdapter.ACTION_DISCOVERY_FINISHED);
getActivity().registerReceiver(FoundReceiver, filter);

mBluetoothAdapter.startDiscovery();

为了填充BLE列表，下面的代码工作正常。

private final BroadcastReceiver FoundReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {

String action = intent.getAction();

// When discovery finds a new device
if (BluetoothDevice.ACTION_FOUND.equals(action)) {
    // Get the BluetoothDevice object from the Intent
    BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
    if (!bleName.contains(device)) {
        if(device.getName() != null){
            bleName.add(device.getName());
        }
        Toast.makeText(getActivity(), "name: " + device.getName() + " " + device.getAddress(), Toast.LENGTH_LONG).show();
        bedListADPT = new BleList(context, bleName);
        listView.setAdapter(bedListADPT);
        if(!dvcNameBle.containsKey(device.getName())) {
            dvcNameBle.put(device.getName(), device);
        }
        bedListADPT.notifyDataSetChanged();
    }

}
// When discovery cycle finished
if (BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(action)) {
    if (bleName == null || bleName.isEmpty()) {
        Toast.makeText(getActivity(), "No Devices", Toast.LENGTH_LONG).show();
    }
}
}
};

现在，当用户点击列表项时，它应该与该BLE名称配对。

点击列表项目的活动

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

@Override
public void onItemClick(AdapterView<?> arg0, View arg1,
                        int position, long arg3) {
    Toast.makeText(getActivity(),bedListADPT.getItem(position).toString(),Toast.LENGTH_LONG).show();

    IntentFilter filter = new IntentFilter("android.bluetooth.device.action.PAIRING_REQUEST");

   /**
     * Registering a new BTBroadcast receiver from the Main Activity context
     * with pairing request event
     */
    selectedDevice = bedListADPT.getItem(position).toString();
    getActivity().registerReceiver(new PairingRequest(dvcNameBle,selectedDevice), filter);
    Toast.makeText(getActivity(),""+dvcNameBle.size(),Toast.LENGTH_LONG).show();

}
});

下面的广播接收器与BLE配对

public  class PairingRequest extends BroadcastReceiver {
    private static HashMap<String, BluetoothDevice> mdvcNameBle = new HashMap<String, BluetoothDevice>();
    private static String mselectedDevice = "";
    public PairingRequest() {
        super();
    }

    public PairingRequest(HashMap<String, BluetoothDevice> dvcNameBle, String mselectedDevice){
        super();
        this.mdvcNameBle = dvcNameBle;
        this.mselectedDevice = mselectedDevice;
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals("android.bluetooth.device.action.PAIRING_REQUEST")) {
            try {
                BluetoothDevice device = mdvcNameBle.get(mselectedDevice);

                int pin=intent.getIntExtra("android.bluetooth.device.extra.PAIRING_KEY", 0);
                //the pin in case you need to accept for an specific pin
                Log.d("PIN", " " + intent.getIntExtra("android.bluetooth.device.extra.PAIRING_KEY",0));
                //maybe you look for a name or address
                Log.d("Bonded", device.getName());
                byte[] pinBytes;
                pinBytes = (""+pin).getBytes("UTF-8");
                device.setPin(pinBytes);
                //setPairing confirmation if neeeded
                device.setPairingConfirmation(true);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }
}

在清单文件中，我已经声明了广播接收器和应用程序所需的权限

<receiver android:name=".PairingRequest">
        <intent-filter>
            <action android:name="android.bluetooth.device.action.PAIRING_REQUEST" />
        </intent-filter>
</receiver>

<uses-permission android:name="android.permission.BLUETOOTH"  android:label="BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

当我打电话时

PairingRequest

任何帮助都会非常明显。请帮我解决这个问题。

我得到了答案

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();
}

如果上面的代码在API 23中不起作用，那么请快速检查Android权限。

    // Quick permission check
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        int permissionCheck = getActivity().checkSelfPermission("Manifest.permission.ACCESS_FINE_LOCATION");
        permissionCheck += getActivity().checkSelfPermission("Manifest.permission.ACCESS_COARSE_LOCATION");
        if (permissionCheck != 0) {

            this.requestPermissions(new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION}, 1001); //Any number
        }
    }
