以下是Android Studio中实现蓝牙连接的代码示例:
1. 导入蓝牙相关的包:
```java
import android.bluetooth.BluetoothAdapter;
import android.bluetooth.BluetoothDevice;
import android.bluetooth.BluetoothSocket;
```
2. 初始化蓝牙适配器:
```java
BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
```
3. 判断设备是否支持蓝牙:
```java
if (bluetoothAdapter == null) {
// 设备不支持蓝牙
// 进行相应的处理
}
```
4. 判断蓝牙是否打开,如果没有打开则请求打开蓝牙:
```java
if (!bluetoothAdapter.isEnabled()) {
Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);
}
```
5. 扫描蓝牙设备:
```java
bluetoothAdapter.startDiscovery();
```
6. 监听蓝牙设备的扫描结果:
```java
private final BroadcastReceiver mReceiver = new BroadcastReceiver() {
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (BluetoothDevice.ACTION_FOUND.equals(action)) {
BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
// 处理扫描到的蓝牙设备
}
}
};
```
7. 连接蓝牙设备:
```java
BluetoothDevice device = bluetoothAdapter.getRemoteDevice(deviceAddress);
BluetoothSocket socket = device.createRfcommSocketToServiceRecord(MY_UUID);
socket.connect();
```
请注意,以上代码仅为示例,实际使用时需要根据具体需求进行适当的修改和完善。
