Android WIFI扫描仪应用程序，用于更改间隔。

Question

当前，我正在开发基于Android 26级的WIFI扫描器应用。 现在，我根据Android官方晒黑材料（https://developer.android.com/guide/topics/connectivity/wifi-scan）使用按钮手动执行WIFI扫描任务。它可以成功工作。

但是，我想设置WIFI扫描仪间隔计时器。我在互联网上做了一些调查。有人说WIFI扫描仪间隔计时器基于硬件。您无法将其固定为一个值。因此，我只是假设，如果我的设备的WIFI间隔性能为10秒，则如何使用30秒的WIFI扫描计时器设置或编码它。

非常感谢。

公共类DroneScanningPage扩展了AppCompatActivity {

private WifiManager dronesignalManger;
private ListView scanninglistView;
private Button scanningButton;
private int size = 0 ;
private List<ScanResult> scaningresultsList;
private ArrayList<String> scanningarrayList =new ArrayList<>();
private ArrayAdapter scanningarrayAdapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_dronescanningpage);
    Intent intent = getIntent();
    scanningButton =findViewById(R.id.scanBtn);
    scanningButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            scanWifi();

        }
    });

    scanninglistView = findViewById(R.id.dronedetectorscanningList);
    dronesignalManger = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);

    if (!dronesignalManger.isWifiEnabled()) {
        Toast.makeText(this, "Please turn on the WiFi for Drone detection", Toast.LENGTH_LONG).show();
        dronesignalManger.setWifiEnabled(true);
    }

    scanningarrayAdapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, scanningarrayList);
    scanninglistView.setAdapter(scanningarrayAdapter);
    scanWifi();
}

private void scanWifi() {
    scanningarrayList.clear();
    registerReceiver(dronesignalReceiver, new IntentFilter(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION));
    dronesignalManger.startScan();
    Toast.makeText(this, "Scaning the drone...", Toast.LENGTH_SHORT).show();
}

BroadcastReceiver dronesignalReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        scaningresultsList = dronesignalManger.getScanResults();
        unregisterReceiver(this);

        for (ScanResult scanResult : scaningresultsList) {
            scanningarrayList.add(scanResult.SSID + " - " + scanResult.capabilities + " - " + scanResult.BSSID + " - " + scanResult.frequency + " - " + scanResult.level);
            scanningarrayAdapter.notifyDataSetChanged();
        }
    }
};
