Java 如何检查WiFi扫描限制是启用还是禁用？

我有一个开发场景，需要检查WiFi限制选项是启用还是禁用？
如果它是启用的，那么我希望以编程方式禁用它

private fun prepareForWiFiScan() {

 Toast.makeText(this, "Wifi scan preparation started", Toast.LENGTH_SHORT).show()
        circularProgressbar.visibility = View.VISIBLE
        wiFiManager = applicationContext.getSystemService(Context.WIFI_SERVICE) as WifiManager
        if (!wiFiManager.isWifiEnabled) {
            wiFiManager.isWifiEnabled = true
        }
        wiFiScanReceiver = object : BroadcastReceiver() {
            override fun onReceive(context: Context, intent: Intent) {
                Toast.makeText(this@MainActivity, "Wifi scan finished", Toast.LENGTH_SHORT).senter code herehow()
                val i'sSuccess: Boolean = when {
                    android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M -> intent.getBooleanExtra(
                            WifiManager.EXTRA_RESULTS_UPDATED,
                            false
                    )
                    else -> intent.getBooleanExtra(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION, false)
                }
                circularProgressbar.visibility = View.GONE
                when (isSuccess) {
                    true -> scanSuccess()
                    false -> scanFail()
                }
            }
        }
        registerReceiverAndStartScan()
    }

 private fun registerReceiverAndStartScan() {
        val intentFilter = IntentFilter()
        intentFilter.addAction(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION)
        registerReceiver(wiFiScanReceiver, intentFilter)
        val success = wiFiManager.startScan()
        if (!success) {
            scanFail()
        }
    }

您必须使用广播接收器来接收此信息。检查这里

在android 10之前，我们无法检查WiFi扫描节流阀是启用还是禁用。然而，在android R中，增加了一种新方法来检查WiFi扫描限制是启用还是禁用。 请参考以下链接。

实际上，您也可以使用

Settings.Global.getInt(this.getContentResolver(), "wifi_scan_throttle_enabled")

如果启用了wifi限制，则返回

1

，否则返回

0

，

如果您向我们提供您工作的代码片段，那就太好了。
