以下是Android Studio连接蓝牙家电的基本步骤:
1. 添加蓝牙权限
在AndroidManifest.xml文件中添加以下权限:
```
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
```
2. 搜索蓝牙设备
使用BluetoothAdapter类搜索可用的蓝牙设备。以下是搜索蓝牙设备的示例代码:
```
BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
Set<BluetoothDevice> pairedDevices = bluetoothAdapter.getBondedDevices();
for (BluetoothDevice device : pairedDevices) {
String deviceName = device.getName();
String deviceMacAddress = device.getAddress();
}
```
3. 连接蓝牙设备
使用BluetoothSocket类连接蓝牙设备。以下是连接蓝牙设备的示例代码:
```
BluetoothDevice device = bluetoothAdapter.getRemoteDevice(deviceMacAddress);
BluetoothSocket socket = device.createRfcommSocketToServiceRecord(UUID.fromString("00001101-0000-1000-8000-00805F9B34FB"));
socket.connect();
```
4. 发送数据到家电
使用BluetoothSocket类将数据发送到家电。以下是发送数据到家电的示例代码:
```
OutputStream outputStream = socket.getOutputStream();
String message = "Hello, home appliance!";
outputStream.write(message.getBytes());
```
5. 接收来自家电的数据
使用BluetoothSocket类接收来自家电的数据。以下是接收来自家电的数据的示例代码:
```
InputStream inputStream = socket.getInputStream();
byte[] buffer = new byte[1024];
int bytes;
while ((bytes = inputStream.read(buffer)) > 0) {
String message = new String(buffer, 0, bytes);
}
```
以上是Android Studio连接蓝牙家电的基本步骤。实际应用中,可能需要根据不同的家电设备和通信协议进行相应的修改。
