Question

我正在尝试每秒扫描一次接入点。这就是我在做什么。

      if (isScanning()) {               
            new Timer().schedule(new TimerTask() {
                @Override
                public void run()
                {   
                    results = manager.getScanResults();
                    manager.startScan();                                            
                }                   
            }, 0,1000); 
            adapter.notifyDataSetChanged();

我正在使用BaseAdapter显示结果。

public View getView(int position, View convertView, ViewGroup parent) {

    ScanResult result = results.get(position);

    if (convertView == null) {
        LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(R.layout.network_list_row, null);

    }
    // Get textview fields
    TextView txtSSID = (TextView) convertView.findViewById(R.id.txtSSID);
    TextView txtBSSID = (TextView) convertView.findViewById(R.id.txtBSSID);
    TextView txtCapabilities = (TextView) convertView
            .findViewById(R.id.txtCapabilities);
    TextView txtFrecuency = (TextView) convertView
            .findViewById(R.id.txtFrecuency);
    TextView txtLevel = (TextView) convertView.findViewById(R.id.txtLevel);

if (result.SSID.equalsIgnoreCase(ScanNetworks.manager
                .getConnectionInfo().getSSID()))
                {
            txtSSID.setText(convertView.getContext().getString(
                    R.string.ssid_msg, result.SSID));
            txtBSSID.setText(convertView.getContext().getString(
                    R.string.bssid_msg, result.BSSID));
            txtCapabilities.setText(convertView.getContext().getString(
                    R.string.capabilities_msg, result.capabilities));
            txtFrecuency.setText(convertView.getContext().getString(
                    R.string.frecuency_msg,
                    Integer.toString(result.frequency)));
            txtLevel.setText(convertView.getContext().getString(
                    R.string.signal_level_msg,
                    Integer.toString(result.level)));
            ;

当我显示扫描结果时，我看到很多重复项。我知道调用startScan（）的每一秒都有重叠。有没有办法可以消除显示屏中的重复项？另外，如何同步startScan（）和getScanresults（）调用？请指教。感谢

如何同步WifiManager.startscan（）和WifiManager.getScanResults？
