如何在Kotlin中设置应用程序，直到授予权限并打开蓝牙

<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

private val REQUEST_ENABLE_BLUETOOTH = 1
private val REQUEST_LOCATION_PERMISSION = 2

private fun checkPermissions() {
    if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
        != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(this,
            arrayOf(Manifest.permission.ACCESS_FINE_LOCATION),
            REQUEST_LOCATION_PERMISSION)
    } else {
        enableBluetooth()
    }
}

override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<out String>, grantResults: IntArray) {
    when (requestCode) {
        REQUEST_LOCATION_PERMISSION -> {
            if (grantResults.isNotEmpty() && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                enableBluetooth()
            } else {
                // 权限被拒绝
            }
        }
    }
}

private fun enableBluetooth() {
    val bluetoothAdapter = BluetoothAdapter.getDefaultAdapter()
    if (bluetoothAdapter == null) {
        // 设备不支持蓝牙
    } else {
        if (!bluetoothAdapter.isEnabled) {
            val enableBluetoothIntent = Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE)
            startActivityForResult(enableBluetoothIntent, REQUEST_ENABLE_BLUETOOTH)
        } else {
            // 蓝牙已经打开
        }
    }
}

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    when (requestCode) {
        REQUEST_ENABLE_BLUETOOTH -> {
            if (resultCode == Activity.RESULT_OK) {
                // 蓝牙已经成功打开
            } else {
                // 用户取消了蓝牙打开请求
            }
        }
    }
