下面是一个简单的示例,演示如何使用Android Studio和Kotlin进行蓝牙连接的管理:
在app的build.gradle文件中,添加以下依赖项:
implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.4.3'
import android.bluetooth.BluetoothAdapter
import android.bluetooth.BluetoothDevice
import android.bluetooth.BluetoothSocket
import kotlinx.coroutines.Dispatchers
import kotlinx.coroutines.withContext
import java.io.IOException
import java.util.*
class BluetoothManager {
private val bluetoothAdapter: BluetoothAdapter? = BluetoothAdapter.getDefaultAdapter()
private var bluetoothSocket: BluetoothSocket? = null
suspend fun connectToDevice(device: BluetoothDevice): Boolean {
return withContext(Dispatchers.IO) {
try {
bluetoothSocket = device.createRfcommSocketToServiceRecord(UUID.randomUUID())
bluetoothSocket?.connect()
true
} catch (e: IOException) {
false
}
}
}
fun disconnect() {
bluetoothSocket?.close()
}
}
class MainActivity : AppCompatActivity() {
private val bluetoothManager = BluetoothManager()
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val device = // 获取要连接的蓝牙设备
CoroutineScope(Dispatchers.Main).launch {
val isConnected = bluetoothManager.connectToDevice(device)
if (isConnected) {
// 连接成功
} else {
// 连接失败
}
}
}
override fun onDestroy() {
super.onDestroy()
bluetoothManager.disconnect()
}
}
请注意,这只是一个简单的示例,实际项目中可能需要更多的错误处理和状态管理。此示例仅用于演示如何使用Android Studio和Kotlin进行蓝牙连接的管理。
