Kir*_*415 2 java android bluetooth
我正在创建一个应通过蓝牙连接到特定设备的应用程序。
我希望我的应用程序与此设备连接,无论它是否已配对。
现在我有这个
private void findDevice() {
Set<BluetoothDevice> pairedDevices = bluetoothAdapter.getBondedDevices();
if (pairedDevices.size() > 0) {
for (BluetoothDevice device : pairedDevices) {
if (device.getName().equals(DEVICE_NAME)) {
bluetoothDevice = device;
deviceFound = true;
break;
}
}
}
}

但此功能仅连接到配对设备。如果我的设备尚未配对,我想配对它。不知道该怎么做。
有人可以给我任何建议吗?
首先请求BLUETOOTH_ADMIN许可。
然后使您的设备可被发现:
private void makeDiscoverable() {
Intent discoverableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
discoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 300);
startActivity(discoverableIntent);
Log.i("Log", "Discoverable ");
}

然后创建一个BroadcastReceiver来监听来自系统的动作:
private BroadcastReceiver myReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
Message msg = Message.obtain();
String action = intent.getAction();
if(BluetoothDevice.ACTION_FOUND.equals(action)){
//Found, add to a device list
}
}
};

并通过注册此BoardcastReceiver开始搜索设备:
private void startSearching() {
Log.i("Log", "in the start searching method");
IntentFilter intentFilter = new IntentFilter(BluetoothDevice.ACTION_FOUND);
BluetoothDemo.this.registerReceiver(myReceiver, intentFilter);
bluetoothAdapter.startDiscovery();
}

设备从BroadcastReceiver进入列表后,从列表中选择您的设备,然后createBond()执行以下操作:
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();
}

然后使用上面的代码来管理绑定设备。
